In adults undergoing rehabilitation after stroke, does 30 minutes of daily stretch of the wrist and finger flexors for four weeks prevent or reverse contracture, decrease pain, or improve upper-limb activity? Are any gains maintained one week and five weeks after the cessation of stretching?
                Randomised controlled trial with concealed randomisation, assessor blinding, and intention-to-treat analysis.
                40 adults undergoing rehabilitation after stroke or stroke-like brain injury, who were unable to actively extend the affected wrist.
                Both groups received routine upper-limb retraining five days a week. In addition, the experimental group received 30 minutes daily stretch of the wrist and finger flexors five days a week for four weeks.
                The primary outcome was contracture, measured as torque-controlled passive wrist extension with the fingers extended. Secondary outcomes were pain at rest measured on a 10-cm visual analogue scale, and upper-limb activity measured using the Motor Assessment Scale. Outcomes were collected at baseline, post-intervention, and one and five weeks after cessation of intervention. Results: The mean effect on passive range of wrist extension was 3.8 [corrected] degrees (95% CI -2.5 to 10.1) [corrected] after 4 weeks of daily stretch, 4.1 degrees (95% CI -4.0 to 12.3) after a week of no stretch, and 3.5 degrees (95% CI -4.6 to 11.7) after a further four weeks.
                These data suggest that four weeks of regular stretching has little or no effect on wrist contracture after stroke. However the estimate of the size of this effect is not sufficiently precise to rule out the possibility of a marginally worthwhile effect. The stretch had no significant effect on upper-limb pain, and did not result in significantly improved upper-limb activity. To evaluate the feasibility and effects of daily stretch positioning for prevention of contractures in stroke patients without arm function.
                Randomized controlled pilot study.
                Stroke rehabilitation ward, U.K.
                Twenty-five subjects drawn from an initial pool of 126 presenting with loss of arm function, all within four weeks of stroke.
                In addition to usual care, subjects in the experimental group (n=13) were prescribed two 30-min stretches for wrist and finger flexors and two 30-min stretches targeting shoulder adductors and internal rotators, per day for up to 12 weeks post stroke. Stretches were carried out by therapists and nursing staff.
                Passive range of wrist extension and shoulder external rotation to standard force or to pain at four, eight and twelve weeks after stroke.
                Compliance was variable. Frequency of positioning was fair from four to eight weeks post stroke but declined after that. Mean (SD) frequency of stretch positions completed between four and eight weeks was 36.5 (13.0) for the wrist, 31.2 (14.1) for the shoulder, out of 56 prescribed. There were no significant effects of treatment. By eight weeks post stroke the mean range of wrist extension and shoulder external rotation lost on the affected side in both groups was approximately 30 degrees.
                The stretch treatment was not well tolerated over many weeks. Statistical power was low due to the large degree of variability of range of motion and small sample size. The regime tested cannot be recommended as a workable treatment to prevent contractures. What is the effectiveness of 12 weeks of nightly stretch in reducing thumb web-space contracture in people with neurological conditions?
                Assessor-blinded, randomised controlled trial.
                Forty-four (one dropout)community-dwelling patients with a neurological condition (14 stroke, 7 traumatic brain injury, 23 spinal cord injury) who had uni or bilateral thumb web-space contractures (60 thumbs).
                The experimental thumbs were splinted into a stretched,abducted position each night for 12 weeks. The control thumbs were not splinted.
                Thumb web-space was measured as the carpometacarpal angle during the application of a 0.9 Nm abduction torque before and after intervention.
                The mean increase in thumb web-space after 12 weeks was 1 deg (95% CI, -1 to 2).
                Intensive stretch administered regularly over three months does not reduce thumb web-space contractures in neurological conditions. To compare the efficacy of short- and long-duration passive stretches with a control treatment for the management of plantarflexion contracture after cast immobilization for ankle fracture.
                Assessor-blinded, randomized controlled trial.
                Hospital physical therapy outpatient departments.
                Adults with plantarflexion contracture (N=150) after cast immobilization for ankle fracture. All subjects were weight bearing or partial weight bearing.
                Exercise only, exercise plus short-duration passive stretch, and exercise plus long-duration passive stretch. All subjects had a 4-week course of exercises. In addition, subjects in the short-duration stretch plus exercise group completed 6 minutes of stretching per day, and subjects in the long-duration stretch plus exercise group completed 30 minutes of stretching per day.
                Lower Extremity Functional Scale and passive dorsiflexion range of motion with the knee bent and straight at baseline, and at 4 weeks and 3 months postintervention.
                One hundred thirty-nine (93%) subjects completed the 4-week assessment and 134 (89%) subjects completed the 3-month assessment. There were no statistically significant or clinically important between-group differences for the primary outcomes.
                The addition of passive stretching confers no benefit over exercise alone for the treatment of plantarflexion contracture after cast immobilization for ankle fracture. Few randomized controlled studies have examined the effects of exercise in patients with ankylosing spondylitis (AS). This study investigated the effects of a 12-week, multimodal exercise program in patients with AS.
                A convenience sample of 30 patients with AS (18 male, 12 female), with a mean age of 34.9 years (SD=6.28), participated in the study. Twenty-six subjects were classified as having stage I AS and 4 subjects were classified as having stage II AS according to the modified New York Criteria.
                This study was a randomized controlled trial. Subjects were assigned to either a group that received an exercise program or to a control group. The exercise program consisted of 50 minutes of multimodal exercise, including aerobic, stretching, and pulmonary exercises, 3 times a week for 3 months. Subjects in both groups received medical treatment for AS, but the exercise group received the exercise program in addition to the medical treatment. All subjects received a physical examination at baseline and at 12 weeks. The examinations were conducted under the supervision of a physician who specialized in physical medicine and rehabilitation and included the assessment of spinal mobility using 2 methods: clinical measurements (chin-to-chest distance, Modified Schober Flexion Test, occiput-to-wall distance, finger-to-floor distance, and chest expansion) and inclinometer measurements (gross hip flexion, gross lumbar flexion, and gross thoracic flexion). In addition, vital capacity was measured by a physiologist, and physical work capacity was evaluated by a doctorally prepared exercise instructor.
                The measurements of the exercise group for chest expansion, chin-to-chest distance, Modified Schober Flexion Test, and occiput-to-wall distance were significantly better than those of the control group after the 3-month exercise period. The spinal movements of the exercise group improved significantly at the end of exercise program, but those of the control group showed no significant change. In addition, the results showed that the posttraining value of gross thoracic flexion of the exercise group was significantly higher than that of the control group. Physical work capacity and vital capacity values improved in the exercise group but decreased in the control group.
                In this study, a multimodal exercise program including aerobic, stretching, and pulmonary exercises provided in conjunction with routine medical management yielded greater improvements in spinal mobility, work capacity, and chest expansion. The aim of this assessor-blind randomised controlled trial was to determine the effect of four weeks of 30 minute stretches each weekday on extensibility of the hamstring muscles in people with recent spinal cord injuries. A consecutive sample of 16 spinal cord-injured patients with no or minimal voluntary motor power in the lower limbs and insufficient hamstring muscle extensibility to enable optimal long sitting were recruited. Subjects' legs were randomly allocated to experimental and control conditions. The hamstring muscles of the experimental leg of each subject were stretched with a 30 Nm torque at the hip for 30 minutes each weekday for four weeks. The hamstring muscles of the contralateral leg were not stretched during this period. Extensibility of the hamstring muscles (hip flexion range of motion with knee extended, measured with a 48 Nm torque at the hip) of both legs was measured by a blinded assessor at the commencement of the study and one day after the completion of the four-week stretch period. Changes in hamstring muscle extensibility from initial to final measurements were calculated. The effect of stretching was expressed as the mean difference in these changes between stretched and non-stretched legs. The mean effect of stretching was 1 degree (95% CI -2 to 5 degrees). Four weeks of 30 minute stretches each weekday does not affect the extensibility of the hamstring muscle in people with spinal cord injuries. Surgery and radiotherapy commonly cause adverse musculoskeletal problems, particularly loss of strength and range of motion, in the upper quadrant of breast cancer patients. Few well-designed studies have investigated whether these impairments can be prevented. Stretching is an effective technique for increasing range of motion, hence the aim of this study was to investigate whether a stretching program reduced acute musculoskeletal impairments in patients undergoing radiotherapy for breast cancer. Sixty-four women were recruited prior to commencement of radiotherapy following breast cancer surgery. Participants were randomised to either a control or stretch group. Participants in both groups were reviewed by the physical therapist on a weekly basis for approximately 6 weeks, and were given general information about skin care and lymphedema. The control group received no advice about exercise. The stretch group received instruction on low-load, prolonged pectoral stretches, which were to be performed daily and were checked at weekly visits. Shoulder range of motion, strength, arm circumference, and quality of life measurements were taken prior to, and at completion of radiotherapy, and at 7 months after radiotherapy. There was no difference in any outcome between groups. Breast symptoms increased for both groups during radiotherapy, without loss of strength or range of movement. The incidence of lymphedema during the study was low for both groups and did not differ between groups. The pectoral stretching program did not influence the outcomes measured because the symptoms reported by patients were not a consequence of contracture. The purpose of this study was to do a pilot test of the effectiveness of prolonged stretch (use of splint) in reducing knee flexion contractures more than a traditional program of passive range of motion (PROM) in a group of nursing home residents.
                The subjects were 28 nursing home residents with 10 degrees or more of knee flexion contracture bilaterally. Eighteen subjects completed the study.
                Data were collected prior to the initiation of the intervention and at monthly intervals during the 6 months of treatment. Repeated measurements were made of hip, knee, and ankle range of motion (ROM); the torque required to maintain passive impairment. knee extension; knee pain; several indicators of function; and cognitive impairment. Both legs of each subject received PROM and manual stretching twice a week; in addition, one leg was given a prolonged stretch (use of a splint) five times a week.
                There were no differences in knee ROM between the side that received prolonged stretching and the side that received only PROM and manual stretching at the beginning of the study. No differences in ROM or torque measurements existed between the side that received prolonged stretching and the side that received only PROM and manual stretching at any interval, nor in ROM or torque over time for either side. Because of the low statistical power of the study, the results should be viewed with caution.
                Physical therapists need to question whether prolonged stretch for nursing home residents with knee flexion contractures greater than 10 degrees is of any greater benefit than PROM and manual stretching. Investigations of other treatment protocols and treatment doses are needed, including work in the area of prevention of knee flexion contractures. For the pilot group of nursing home residents studied, gains in knee extension did not occur with the use of prolonged stretch for 3 hours a day, 5 days per week. [Steffen TM, Mollinger LA. Low-load, prolonged stretch in the treatment of knee flexion contractures in nursing home residents. To determine the efficacy of positioning the affected shoulder in flexion and external rotation to prevent contracture shortly after stroke.
                Prospective, parallel-group, randomized controlled trial.
                Four metropolitan mixed rehabilitation units.
                A volunteer sample of 36 subjects (minus 5 dropouts), whose mean age was 68 years and had had their first stroke within the past 20 days.
                The experimental group received two 30-minute sessions a day, 5 days a week, for 4 weeks, during which the affected upper limb was placed in maximum comfortable external rotation and 90 degrees of flexion. Both the experimental and control groups received up to 10 minutes of shoulder exercises and standard upper-limb care.
                Contracture was measured as the maximum passive shoulder external rotation and flexion of the affected side as compared with the intact side. Measures were taken at 2 and 6 weeks after stroke by an assessor blinded to group allocation.
                The 30-minute program of positioning the shoulder in maximum external rotation significantly reduced the development of contractures in the experimental group, compared with the control group ( P =.03). The 30-minute program of positioning the shoulder in 90 degrees of flexion did not prevent contractures in the experimental group as compared with the control group ( P =.88).
                At least 30 minutes a day of positioning the affected shoulder in external rotation should be started as soon as possible for stroke patients who have little activity in the upper arm. To determine the effects of stretching before and after physical activity on risks of injury and soreness in a community population.
                Internet-based pragmatic randomised trial conducted between January 2008 and January 2009.
                International.
                A total of 2377 adults who regularly participated in physical activity.
                Participants in the stretch group were asked to perform 30 s static stretches of seven lower limb and trunk muscle groups before and after physical activity for 12 weeks. Participants in the control group were asked not to stretch.
                Participants provided weekly on-line reports of outcomes over 12 weeks. Primary outcomes were any injury to the lower limb or back, and bothersome soreness of the legs, buttocks or back. Injury to muscles, ligaments and tendons was a secondary outcome.
                Stretching did not produce clinically important or statistically significant reductions in all-injury risk (HR=0.97, 95% CI 0.84 to 1.13), but did reduce the risk of experiencing bothersome soreness (mean risk of bothersome soreness in a week was 24.6% in the stretch group and 32.3% in the control group; OR=0.69, 95% CI 0.59 to 0.82). Stretching reduced the risk of injuries to muscles, ligaments and tendons (incidence rate of 0.66 injuries per person-year in the stretch group and 0.88 injuries per person-year in the control group; HR=0.75, 95% CI 0.59 to 0.96).
                Stretching before and after physical activity does not appreciably reduce all-injury risk but probably reduces the risk of some injuries, and does reduce the risk of bothersome soreness.
                anzctr.org.au 12608000044325. Although contractures in patients in long-term care institutions are an important issue, there have been only a few studies that have evaluated interventions for contractures. The purpose of this study was to determine the effectiveness of a bed positioning program (BPP) for the treatment of patients with knee flexion contractures.
                Sixteen patients with a high level of cognitive and functional impairment (mean age=82 years, SD=6.48, range=71-93) in a chronic care hospital participated in the study.
                The BPP consisted of stretching a patient's knee into extension and then securing and maintaining the position for a period of 40 minutes, 4 times per week. Participants were randomly assigned to 2 groups (n=8 in each group). One group received a BPP for 8 weeks, followed by 8 weeks of no intervention. The other group received the intervention in the reverse order. Once a week, participants were assessed for range of knee extension, knee pain, and skin integrity.
                Twelve participants completed the study. There was no improvement in participants' range of knee extension during the intervention period. Overall, there was no difference in mean range of knee extension between the intervention period and the no-intervention period.
                The results of this study do not support the use of a BPP for treating patients with knee flexion contractures. A controlled study of 39 consecutively-admitted patients with ankylosing spondylitis was conducted to assess the effects of daily passive stretching of the hip joints during a 3-week in-patient physiotherapy course. Measurements were performed by an independent assessor on admission, at discharge and six months after discharge. Results showed that passive stretching resulted in a significant increase in the range of all movements of the hip joints except flexion during the physiotherapy course. Follow-up at 6 months in seven patients suggested that this increase in range of movement could be maintained by patients who had been performing the stretching exercises regularly. We suggest that the inclusion of passive stretching of the hip joint in the treatment of patients with ankylosing spondylitis will increase the range of movement and thus improve function and influence posture. We investigated the effects of home-based daily exercise on joint mobility, functional capacity, pain, and depression in patients with ankylosing spondylitis (AS). The patients were randomly assigned to a wait-list control group or to an exercise-therapy group. The exercise-therapy group performed a 20-min exercise program once per day for 8 consecutive weeks. After 8 weeks, compared with the control group, the exercise group showed improvements in joint mobility (cervical flexion, extension, shoulder flexion, abduction, hip abduction, and knee flexion), finger-floor distance, and functional capacity. Pain and depression scores were significantly lower after the exercise program in the exercise group than in the control group. These findings indicate that exercise therapy increases joint mobility and functional capacity, and decreases pain and depression in patients with AS. Home-based exercise, which is easily accessible to patients, might be an effective intervention for AS. To assess the adherence to and effects of a 12-month combined strength and stretching home exercise regimen versus stretching alone, on patient outcome after lumbar disk surgery.
                Randomized controlled trial.
                Departments of physical medicine and rehabilitation and orthopedics at a Finnish hospital.
                Patients (N=126) were randomized into either a combined strength training and stretching group (STG, n=65) or a control group (CG, n=61).
                The STG was instructed to perform strength training and both the STG and CG were instructed in the same stretching and stabilization exercises for 12 months.
                Pain on the visual analog scale (VAS), the Oswestry and the Million disability indexes, isometric and dynamic trunk muscle strength, mobility in the lumbar spine, and straight-leg raising were measured.
                The trial was completed by 71% and 77% of the patients from the STG and the CG, respectively. The mean strength training frequency decreased from 1.5 to 0.6 times a week in the STG during the intervention. The mean stretching frequency decreased from 3.7 to 1.6 times a week in both groups. Median back and leg pain varied between 17 and 23 mm (VAS), and the Million and Oswestry indices varied between 14 and 23 points 2 months postoperatively. No statistically significant changes took place in these outcome measures during the 12-month follow-up in both groups. The changes in isometric trunk extension favored the STG ( P =.016) during the first 2 months. However, during the whole 12-month training period, both dynamic and isometric back extension and flexion strength, as well as mobility of the spine and repetitive squat-test results, improved significantly in both groups, and no differences were found in any of the physical function parameters between the STG and CG.
                At the 12-month follow-up, no statistically significant changes were found in the physical function, pain, or disability measures between the groups. In the STG, training adherence with regard to training frequency and intensity remained too low to lead to specific training-induced adaptations in the neuromuscular system. Progressive loading, supervision of training, and psychosocial support is needed in long-term rehabilitation programs to maintain patient motivation. To determine the effect of 4 weeks of 30 minutes of daily stretching on ankle mobility in patients with recent spinal cord injuries (SCIs).
                Assessor-blinded randomized controlled trial.
                Two spinal injury units in Sydney, Australia.
                Consecutive sample of 14 recently injured patients with paraplegia and quadriplegia.
                Treated ankles were stretched continuously into dorsiflexion with a torque of 7.5 N x m for 30 minutes each weekday for 4 weeks. Contralateral ankles received no stretches.
                Passive torque-angle curves for both ankles were obtained at study commencement, then at weeks 2, 4, and 5 (ie, during, at the end of, and 1 week after the stretching program). Torque-angle measurements were obtained with the knee extended and flexed. Mean values for parameters (baseline angle, angle at 10 N x m, slope) describing the characteristics of the torque-angle curves were derived for each knee position. Changes from pretest to each subsequent test were calculated, as well as 95% confidence intervals (CIs) for differences in these changes between stretched and controlled ankles.
                The stretching intervention did not significantly change any of the 3 parameters describing the torque-angle curves of the ankle in either knee position. At the beginning of the study, the mean (+/-SD) angles obtained with the application of a standardized torque with the knee extended for the control and stretch ankles were 105 degrees (+/- 10.4 degrees) and 106 degrees (+/- 9.8 degrees), respectively. After 4 weeks, these values were 106 degrees (+/- 10.6 degrees) and 107 degrees (+/- 10.6 degrees) (mean difference in change of angle = 0 degrees; 95% CI, -3.3 degrees to 3.3 degrees).
                Thirty minutes of daily stretching for 4 weeks does not significantly change ankle mobility in recently injured patients with SCIs. The purpose of this clinical trial was to evaluate the impact of a 4-month comprehensive protocol of strengthening and flexibility exercises developed by our research group versus conventional exercises for patients with Ankylosing Spondylitis (AS) on functional and mobility outcomes.
                Randomized controlled trial. Forty-five patients diagnosed with AS according to the modified criteria of New York were allocated to control or experimental groups using a random numbers table. The control group was treated with a conventional protocol of physical therapy in AS, whereas the experimental group was treated with the protocol suggested by our research group. The conventional intervention consisted of 20 exercises: motion and flexibility exercises of the cervical, thoracic, and lumbar spine; stretching of the shortened muscles; and chest expansion exercises. The experimental protocol is based on the postural affectation of the AS and the treatment of the shortened muscle chains in these patients according to the Global Posture Reeducation (GPR) method. This intervention employs specific strengthening and flexibility exercises in which the shortened muscle chains are stretched and strengthened. The study lasted 4 mos. During this period, patients received a weekly group session managed by an experienced physiotherapist. Each session lasted an hour, and there were 15 total sessions. Changes in activity, mobility, and functional capacity were evaluated by an assessor blinded to the intervention, using the following previously validated scores from the Bath group: BASMI (tragus to wall distance, modified Schober test, cervical rotation, lumbar side flexion, and intermalleolar distance), BASDAI (The Bath Ankylosing Spondylitis Disease Activity Index), and BASFI (The Bath Ankylosing Spondylitis Functional Index).
                Both groups showed an improvement (prepost scores) in all the outcome measures, mobility measures of the BASMI index, as well as in BASFI and BASDAI indexes. In the control group, the improvement in tragus to wall distance (P=0.009) and in lumbar side flexion (P=0.02) was statistically significant. Although the rest of the outcomes also improved, they did not reach a significant level (P>0.05). In the experimental group, the improvement in all the clinical measures of the BASMI index (P<0.01) and in the BASFI index (P=0.003) was statistically significant. The intergroup comparison between the improvement (prepost scores) in both groups showed that the experimental group obtained a greater improvement than the control group in all the clinical measures of the BASMI index, except in tragus to wall distance, as well as in the BASFI index.
                The experimental protocol developed by our research group, based on the GPR method and specific strengthening and flexibility exercises of the muscle chains, offers promising results in the management of patients suffering from AS. Further trials on this topic are required. This study expanded previous NIOSH-IRS research examining the effects of rest breaks and stretching exercises on symptoms and performance in data-entry workers.
                All workers spent 4 weeks with conventional breaks (two 15 min breaks per day) and 4 weeks with supplementary breaks (two 15 min breaks plus four 5 min breaks per day). One-half were assigned at random to a group instructed to perform brief stretching exercises during breaks. The remainder comprised the "no stretching" (control) group.
                51 workers (stretch group n = 21; no stretch group n = 30) completed the study symptom questionnaires. Discomfort and eyestrain were significantly lower with supplementary breaks, and supplementary breaks attenuated accumulation of discomfort and eyestrain during work sessions. Data-entry speed was significantly faster with supplementary breaks so that work output was maintained, despite replacing 20 min of work time with break time. In the stretch group, workers reported stretching during only 25% of conventional breaks and 39% of supplementary breaks, and no significant effects of stretching on discomfort or performance were observed.
                These results provide further converging evidence that supplementary breaks reliably minimize discomfort and eyestrain without impairing productivity. Low compliance in performing stretches prevented valid assessment of stretching effects. Further research on stretching exercises and exercise compliance is warranted. This study was designed to determine whether an 8-week isokinetic muscle-strength-training program improved the functional health status of patients with osteoarthritis of the knee joint. Twenty volunteers with osteoarthritis of the knee joint were randomly assigned to either an experimental (n=10) or control (n=10) group. The experimental group completed six sets of five maximal contractions three times per week for 8 weeks on a Cybex II dynamometer at 90 degrees per second. Both groups were pre- and posttest for extension and flexion strength of the right and left legs, the 50-foot walk time, range of motion at the knee joint, the Osteoarthritis Screening Index (OASI), and the Arthritis Impact Measurement Scale (AIMS). There was a significant decrease in pain and stiffness, and a significant increase in mobility. There was also a significant decline in arthritis activity in the experimental group as measured by the OASI and AIMS. The experimental group significantly increased in all strength measures, while the control group increased in only right leg flexion and left leg extension across the training period. For years, stretching has been an integral part of fitness, practice, and rehabilitation programs to decrease muscle stiffness and relieve pain associated with it. The increased joint range of motion (ROM), indicating the degree of muscle flexibility, has a benefit of stretching proven for healthy tissues.
                The objective of our study was the assessment of the effects of stretching in the rehabilitation of hamstring injuries.
                We followed up 80 Greek athletes, of average age 20.5 yr, with "second-degree" strain of the hamstring muscles. The athletes were divided into two groups, A and B. For both groups, we estimated the time required for the rehabilitation of the decreased knee ROM and the total time before the athletes could return to a full training program.
                Group B, which carried out a more intensive stretching program, was found to have a statistically significant shorter time of regaining normal ROM (5.57 +/- 0.71 d) and rehabilitation period (13.27 +/- 0.71 d) in comparison with group A (7.32 +/- 0.525 d and 15.05 +/- 0.81 d, respectively).
                Our results suggest that stretching is of great importance in treating muscle strain injuries in that it improves the effectiveness of the rest rehabilitation program. The effectiveness of an exercise intervention for people in early and midstage Parkinson's disease (stages 2 and 3 of Hoehn and Yahr) in improving spinal flexibility and physical performance in a sample of community-dwelling older people is described.
                Fifty-one men and women, aged 55-84 years, identified through advertisement, local support groups, and local neurologists were enrolled into a randomized, controlled trial. Subjects were assigned randomly to an intervention or a usual care arm (i.e., no specific exercise). Of the original 51 participants, 46 completed the randomized, controlled trial. Participants in the exercise arm (n = 23) received individual instruction three times per week for 10 weeks. Participants in the usual care arm (n = 23) were "wait listed" for intervention.
                Changes over 10 weeks in spinal flexibility (i.e., functional axial rotation) and physical performance (i.e., functional reach, timed supine to stand) were the primary outcome measures.
                MANOVA conducted for the three primary outcome variables demonstrated significant differences (P < or = .05) between the two groups. Further analysis using ANOVA demonstrated significant differences between groups in functional axial rotation and functional reach for the intervention compared with the control group. There was no significant difference in supine to sit time.
                Study results demonstrate that improvements in axial mobility and physical performance can be achieved with a 10-week exercise program for people in the early and midstages of PD. A randomized clinical trial.
                To evaluate long-term clinical and economical effects of a light mobilization program on the duration of sick leave for patients with subacute low back pain.
                Twelve-month follow-up results from a previous study showed that early intervention with examination at a spine clinic, giving the patients information, reassurance, and encouragement to engage in physical activity as normal as possible had significant effect in reducing sick leave. At 12-month follow-up, 68.4% in the intervention group were off sick leave, as compared with 56.4% in the control group. Patients in this study were followed-up for a period of 3 years to investigate possible long-term effects.
                Four hundred fifty-seven patients placed on a sick list for 8 to 12 weeks for low back pain were randomized into two groups: an intervention group (n = 237) and a control group (n = 220). The intervention group was examined at a spine clinic and given information and advice to stay active. The control group was not examined at the clinic but was treated within the primary health care.
                Over the 3 years of observation, the intervention group had significantly fewer days of sickness compensation (average 125.7 d/person) than the control group (169.6 d/person). This difference is mainly caused by a more rapid return to work during the first year. There was no significant difference for the second or third year. In particular, there is no increased risk for reoccurrence of illness from early return to work. At 6-month follow-up, patients in the intervention group were less likely to use bed rest and more likely to use stretching and walking to cope with their back pain compared with the control group. This effect diminished. At 12-month follow-up, the only significant difference between the groups was in the use of stretching. Economic returns of the intervention were calculated in terms of increases in the net present value of production for the society because of the reduction in number of days on sick leave. Net benefits accumulated over 3 years of treating the 237 patients in the intervention group amount to approximately 2,822 dollars per person.
                For patients with subacute low back pain, a brief and simple early intervention with examination, information, reassurance, and encouragement to engage in physical activity as normal as possible had economic gains for the society. The effect occurred during the first year after intervention. There were no significant long-term effects of the intervention. The initial gain obtained during the first year does not lead to any increased costs or increased risks for reoccurrence of illness over the next 2 years. Restricted physical activity as a consequence of chronic disease or injury is a predictor of functional decline. The aim of this study was to test the hypothesis that a 6- month multidimensional training program would have sustained beneficial effects upon the physiological, functional and psychological condition of old women with a recent history of falls.
                Participants were 65 home-dwelling women (70-90 years) identified from hospital records as having had an accidental fall. After assessment of muscle strength, balance performance, walking speed, balance confidence, and physical activity level, the participants were randomly assigned to a control group (n=33) or a training group (n=32), who performed a multidimensional training program including moderate resistance exercise and balance exercise twice weekly for 6 months. Measurements were repeated after 6 and 12 months.
                Six months of multidimensional training resulted in significant improvements and between-group differences in isometric knee extension strength (p<0.05), trunk extension/ flexion strength (p<0.001), habitual/maximal walking speed (p<0.001) and balance performance (p<0.001). At follow-up, 6 months after intervention, these improvements were preserved in the training group and there was also a significant between- group difference with regard to balance confidence. No between-group differences were found concerning number of falls or physical activity level during the one-year study period.
                A multi-dimensional training program produced significant improvements in physiological and functional risk factors for falls and disability in women aged 70-90 years with a recent history of falls. The present study sought to investigate the effects of preexercise stretching on delayed onset muscle soreness (DOMS), i.e. soreness, tenderness and loss of muscle force, that usually occurs after strenuous or unaccustomed eccentric exercise. Ten female volunteers performed 10 sets of 10 maximal isokinetic eccentric contractions for knee flexion with both legs after a 5-min ergometer cycling warm-up. Prior to the exercise for one leg, randomly chosen, 4 x 20 s of static stretching for the hamstring muscle group was implemented. Rated soreness, tenderness on algometer pressure and loss of maximal eccentric contractile force was evaluated preexercise and 24, 48 and 96 h postexercise. The exercise bout produced severe DOMS, with parameters peaking and troughing at 48 h postexercise. However, no significant differences were found, regarding any of the parameters, when comparing stretched and nonstretched legs. The present study thus suggests that preexercise static stretching has no preventive effect on the muscular soreness, tenderness and force loss that follows heavy eccentric exercise. Ultrasound increases soft tissue extensibility and may be an effective adjunct in the treatment of knee contractures secondary to connective tissue shortening. A randomized clinical trial was conducted to determine the effectiveness of ultrasound in relieving stiffness and pain in patients (age mean = 67.5 years, SD = 13.0) who had osteoarthritis (OA) and a chronic knee contracture. Subjects received 12 treatments of exercise preceded by either ultrasound (n = 34) or sham ultrasound (n = 35) and a blinded evaluation at baseline, after treatment, and 2 months after treatment. MANCOVA controlling for baseline scores showed that there were no significant differences in knee active range of motion (ROM) (goniometry) or pain (visual analogue scale) between experimental and control groups. Possible explanations for the no difference finding involve dosage issues, muscle shortening, transiency of effects, and the effects of exercise. Paired t-tests revealed that both groups significantly improved (p less than 0.05) in active ROM, pain, and gait velocity, and maintained improvement for at least 2 months. Although ultrasound may not contribute to the management of patients with chronic knee stiffness and OA, benefits of the exercise program and increased activity secondary to program participation probably influenced the overall improvement. Adequate and intensive rehabilitation is an important requirement for successful total knee arthroplasty. Although research suggests that Continuous Passive Motion (CPM) should be implemented in the first rehabilitation phase after surgery, there is substantial debate about the duration of each session and the total period of CPM application. A Cochrane review on this topic concluded that short-term use of CPM leads to greater short-term range of motion. It also suggested, however, that future research should concentrate on the treatment period during which CPM should be administered.
                In a randomised controlled trial we investigated the effectiveness of prolonged CPM use in the home situation as an adjunct to standardised PT. Efficacy was assessed in terms of faster improvements in range of motion (RoM) and functional recovery, measured at the end of the active treatment period, 17 days after surgery. Sixty patients with knee osteoarthritis undergoing TKA and experiencing early postoperative flexion impairment were randomised over two treatment groups. The experimental group received CPM + PT for 17 consecutive days after surgery, whereas the usual care group received the same treatment during the in-hospital phase (i.e. about four days), followed by PT alone (usual care) in the first two weeks after hospital discharge. From 18 days to three months after surgery, both groups received standardised PT. The primary focus of rehabilitation was functional recovery (e.g. ambulation) and regaining RoM in the knee.
                Prolonged use of CPM slightly improved short-term RoM in patients with limited RoM at the time of discharge after total knee arthroplasty when added to a semi-standard PT programme. Assessment at 6 weeks and three months after surgery found no long-term effects of this intervention Neither did we detect functional benefits of the improved RoM at any of the outcome assessments.
                Although results indicate that prolonged CPM use might have a small short-term effect on RoM, routine use of prolonged CPM in patients with limited RoM at hospital discharge should be reconsidered, since neither long-term effects nor transfer to better functional performance was detected.
                ISRCTN85759656. This study investigated the effect of muscle stretching during warm-up on the risk of exercise-related injury.
                1538 male army recruits were randomly allocated to stretch or control groups. During the ensuing 12 wk of training, both groups performed active warm-up exercises before physical training sessions. In addition, the stretch group performed one 20-s static stretch under supervision for each of six major leg muscle groups during every warm-up. The control group did not stretch.
                333 lower-limb injuries were recorded during the training period, including 214 soft-tissue injuries. There were 158 injuries in the stretch group and 175 in the control group. There was no significant effect of preexercise stretching on all-injuries risk (hazard ratio [HR] = 0.95, 95% CI 0.77-1.18), soft-tissue injury risk (HR = 0.83, 95% CI 0.63-1.09), or bone injury risk (HR = 1.22, 95% CI 0.86-1.76). Fitness (20-m progressive shuttle run test score), age, and enlistment date all significantly predicted injury risk (P < 0.01 for each), but height, weight, and body mass index did not.
                A typical muscle stretching protocol performed during preexercise warm-ups does not produce clinically meaningful reductions in risk of exercise-related injury in army recruits. Fitness may be an important, modifiable risk factor. Splints are commonly applied to the wrist and hand to prevent and treat contracture after stroke. However, there have been few randomized trials of this intervention. We sought to determine whether wearing a hand splint, which positions the wrist in either a neutral or an extended position, reduces wrist contracture in adults with hemiplegia after stroke.
                Sixty-three adults who had experienced a stroke within the preceding 8 weeks participated. They were randomized to either a control group (routine therapy) or 1 of 2 intervention groups (routine therapy plus splint in either a neutral or an extended wrist position). Splints were worn overnight for, on average, between 9 and 12 hours, for 4 weeks. The primary outcome, measured by a blinded assessor, was extensibility of the wrist and long finger flexor muscles (angle of wrist extension at a standardized torque).
                Neither splint appreciably increased extensibility of the wrist and long finger flexor muscles. After 4 weeks, the effect of neutral wrist splinting was to increase wrist extensibility by a mean of 1.4 degrees (95% CI, -5.4 degrees to 8.2 degrees), and splinting the wrist in extension reduced wrist extensibility by a mean of 1.3 degrees (95% CI, -4.9 degrees to 2.4 degrees) compared with the control condition.
                Splinting the wrist in either the neutral or extended wrist position for 4 weeks did not reduce wrist contracture after stroke. These findings suggest that the practice of routine wrist splinting soon after stroke should be discontinued. Bed rest is a traditional treatment for back pain, yet only in recent years has the therapeutic benefit of this been questioned.
                The aim of this pilot study was to ascertain whether or not 48 hours' bed rest had an effect on the outcome of acute low back pain.
                The study was conducted as a randomized controlled trial to compare a prescription of 48 hours' strict bed rest with controls; the control subjects were encouraged to remain mobile and to have no daytime rest. Nine general practitioners from practices in the West Midlands recruited patients in the age range 16-60 years who presented with low back pain of less than seven days' duration, with or without pain radiation. The outcome measures assessed were: change in straight leg raise and lumbar flexion after seven days, Oswestry and Roland-Morris disability scores after seven days and 28 days, and time taken from work.
                Forty two patients were recruited: 20 were allocated to bed rest and 22 as controls. Compared with the bed rest group the control group had statistically better Roland-Morris scores at day seven (P < 0.05) but not at day 28. At day seven, there were no statistically significant differences between groups in straight leg raise or lumbar flexion measurements although the control group had a better mean lumbar flexion than the bed rest group. The improvement in disability scores at day seven compared with day one was similar for the two groups but more of the control group had fully recovered (defined as scores of one or zero on the Roland-Morris disability scale and five or less on the Oswestry disability scale) by day seven. Remaining mobile did not appear to cause any adverse effects. The number of days lost from work in both groups was equal. A large number of self-remedies and physical therapies were recorded by subjects from both groups.
                The results of this pilot study did not indicate whether bed rest or remaining mobile was superior for the treatment of acute low back pain; however, the study sample was small. Subjects in the control group possibly fared better as they appeared to have better lumbar flexion at day seven. It appears that 48 hours' bed rest cannot be recommended for the treatment of acute low back pain on the basis of this small study. Large-scale definitive trials are required to detect clinically significant differences. To evaluate the effectiveness of a programme of static positional stretches and positioning of the stroke-affected shoulder for maintaining shoulder external rotation and decreasing hemiplegic shoulder pain.
                Randomized controlled trial with pretest and posttest design.
                Inpatient rehabilitation unit.
                Thirty-two participants (17 treatment, 15 comparison) with a first time stroke who were admitted for rehabilitation. Interventions: Treatment participants completed a programme of static positional stretches of the stroke-affected shoulder twice daily and positioned the stroke-affected upper limb in an armrest support at all other times when seated.
                The main outcome measures were pain-free range of motion into external rotation, pain in the stroke-affected shoulder at rest and with movement, motor recovery and functional independence.
                All participants demonstrated a significant loss of external rotation (P = 0.005) with no significant group differences. All participants demonstrated a significant improvement in motor recovery (P < 0.01) and functional independence (P < 0.01) with no significant group differences. There were no significant effects for pain. The comparison group recorded a decrease in mean pain reported with movement from admission to discharge, and the treatment group recorded an increase.
                Participation in the management programme did not result in improved outcomes. The results of this study do not support the application of the programme of static positional stretches to maintain range of motion in the shoulder. The effect of increasing pain for the treatment group requires further investigation. Prospective randomized comparison of 2 rehabilitation programs.
                The objectives of this study were to compare the effectiveness of 2 rehabilitation programs for acute hamstring strain by evaluating time needed to return to sports and reinjury rate during the first 2 weeks and the first year after return to sport. A third objective was to investigate the relationship between functional testing performance and time to return to sports and reinjury rates after return to sport.
                Hamstring muscle strains are common in sports and often result in chronic pain, recurrent hamstring strains, and reduced sports performance. Current rehabilitation programs are primarily developed anecdotally and lack support from prospective, randomized research.
                Twenty-four athletes with an acute hamstring strain were randomly assigned to 1 of 2 rehabilitation groups. Eleven athletes were assigned to a protocol consisting of static stretching, isolated progressive hamstring resistance exercise, and icing (STST group). Thirteen athletes were assigned to a program consisting of progressive agility and trunk stabilization exercises and icing (PATS group). The number of days for full return to sports, injury recurrence within the first 2 weeks, injury recurrence within the first year of returning to sports, and lower-extremity functional evaluations were collected for all subjects and compared between groups.
                The average (+/- SD) time required to return to sports for athletes in the STST group was 37.4 +/- 27.6 days, while the average time for athletes in the PATS group was 22.2 +/- 8.3 days. This difference was not statistically significant (P = .2455). In the first 2 weeks after return to sports, reinjury rate was significantly greater (P = .00343, Fisher's exact test) in the STST group, where 6 of 11 athletes (54.5%) suffered a recurrent hamstring strain after completing the stretching and strengthening program, as compared to none of the 13 athletes (0%) in the PATS group. After 1 year of return to sports, reinjury rate was significantly greater (P = .0059, Fisher's exact test) in the STST group. Seven of 10 athletes (70%) who completed the hamstring stretching and strengthening program, as compared to only 1 of the 13 athletes (7.7%) who completed the progressive agility and trunk stabilization program, suffered a recurrent hamstring strain during that 1-year period.
                A rehabilitation program consisting of progressive agility and trunk stabilization exercises is more effective than a program emphasizing isolated hamstring stretching and strengthening in promoting return to sports and preventing injury recurrence in athletes suffering an acute hamstring strain. Future randomized clinical trials should investigate the potential for progressive agility and trunk stabilization programs in the prevention of hamstring strain injury during sports. A prospective randomized study was undertaken of 50 consecutive patients undergoing surgery for idiopathic carpal tunnel syndrome to determine the value of splintage of the wrist following open carpal tunnel release. Patients were randomized to either be splinted for 2 weeks following surgery or to begin range-of-motion exercises on the first post-operative day. Subjects were evaluated at 2 weeks, 1 month, 3 months, and 6 months after surgery by motor and sensory testing, physical examination, and a questionnaire. Variables assessed included date of return to activities of daily living, dates of return to work at light duty and at full duty, pain level, grip strength, key pinch strength, and occurrence of complications. Patients who were splinted had significant delays in return to activities of daily living, return to work at light and full duty, and in recovery of grip and key pinch strength. Patients with splinted wrists experienced increased pain and scar tenderness in the first month after surgery; otherwise there was no difference between the groups in the incidence of complications. We conclude that splinting the wrist following open release of the flexor retinaculum is largely detrimental, although it may have a role in preventing the rare but significant complications of bowstringing of the tendons or entrapment of the median nerve in scar tissue. We recommend a home physiotherapy programme in which the wrist and fingers are exercised separately to avoid simultaneous finger and wrist flexion, which is the position most prone to cause bowstringing. This study was designed to evaluate, by means of a randomized controlled trial, the effects of a physical activity program incorporating aerobic, strength, and stretching exercises in individuals with osteoarthritis of the knee. We randomly assigned 137 volunteers ages >/=50 to an experimental group or a control group. The experimental group participated in three 1-hour sessions of supervised exercises per week over a 3-month period. The control participants were instructed to continue their usual daily activities, and they attended 1-hour education sessions twice a month. The effectiveness of the program was evaluated using repeated measurements of parameters related to self-reported health status, physical capacity, and joint tenderness.After 3 months, significantly greater improvements were observed in the experimental group than the control group in terms of: arthritis pain (p = 0.02), ability to walk and bend (p = 0.03), aerobic capacity (p < 0.0001), hamstring and low back flexibility (p = 0.003), quadriceps and hamstring strength (p <0.01), and the perception of changes relating to osteoarthritis of the knee and general condition (p < 0.0001). However, no significant differences were observed between the groups in isokinetic strength of the quadriceps (all p's >== 0.05), joint tenderness (p = 0.18), and health perception (p = 0.7). The overall results suggest that this program is effective for older persons with osteoarthritis of the knee and that it could contribute to maintaining their independence and improving their quality of life. This study investigated effects of ankle dorsiflexion range and pre-exercise calf muscle stretching on relative risk of selected injuries in 1093 male Army recruits undertaking 12 weeks of intensive training. Prior to training, ankle dorsiflexion range was measured and recruits were allocated to stretch and control groups using a quasi-random procedure. The stretch group stretched calf muscles under supervision prior to all intense exercise. The control group stretched upper limb muscles instead. Forty-eight injuries were recorded. Survival analysis indicated that ankle dorsiflexion range was a strong predictor of injury (p = 0.03). Definitive evidence of an effect of stretching on injury risk was not found (p = 0.76), but the sample size may have been insufficient to detect such an effect. Ankle plantar-flexion contractures are a common problem following traumatic head injury. Although serial casting is used to correct and prevent ankle plantar-flexion contractures, treatment efficacy has not been evaluated using an experimental design. The aim of this research was to establish the effect of a regimen of casting combined with stretching on passive ankle dorsiflexion motion.
                Nine people who had sustained traumatic closed head injuries and had limited dorsiflexion motion participated in the study.
                A crossover design was used in the study. Subjects were assigned to both experimental and control groups. Torque-controlled measurements of passive ankle dorsiflexion motion were obtained for all subjects before and after 1 week of casting combined with stretching, as well as before and after a 1-week control period. The order of the experimental and control conditions was randomized.
                Passive ankle dorsiflexion increased by a mean of 13.5 degrees (SD = 9.3) during the experimental condition, as compared with a mean decrease of 1.9 degrees (SD = 10.2) during the control condition. The difference between the experimental and control conditions was statistically significant.
                These findings suggest that casting combined with stretching is an effective method of correcting ankle plantar-flexion contractures in patients with traumatic head injuries.
Stretch does not have clinically important effects on joint mobility in people with, or at risk of, contractures if performed for less than seven months. The effects of stretch performed for periods longer than seven months have not been investigated.
