Patients commonly develop shoulder disability and reduction in quality of life (QOL) following neck dissection surgery. There is a lack of studies investigating the impact of preventative rehabilitation to prevent shoulder disability in this population. An exploratory trial was undertaken to investigate this gap in the head and neck cancer literature. Thirty-two subjects were randomly assigned to either one of two groups: early physiotherapy for a period of 3 months following surgery and current routine inpatient care and advice. Blinded measurement of shoulder function and QOL were recorded pre-operatively and at 1 year following surgery. No difference was found using between-group analysis (Mann-Whitney U-Test) for any outcome measures observed. Descriptive data analysis suggests that subjects receiving early physiotherapy had a perception of increased physical well-being when compared with subjects receiving routine care. There may be some clinical significance that subjects receiving a course of physiotherapy did appear to rate their physical well-being higher than those subjects not undergoing rehabilitation. Further research to investigate the preventative effects of physiotherapy on this population should consider the use of head and neck cancer-specific outcome measurement of both shoulder disability and QOL.
                © 2010 Blackwell Publishing Ltd. The usefulness of video-assisted arthroscopic microdiscectomy for the treatment of a herniated lumbar disc has been studied previously. In the current prospective, randomized study, the results of this procedure were compared with those of conventional open laminotomy and discectomy.
                Sixty patients who had objective evidence of a single intracanalicular herniation of a lumbar disc caudad to the first lumbar vertebra were randomized into two groups consisting of thirty patients each; Group 1 was managed with open laminotomy and discectomy, and Group 2 was managed with video-assisted arthroscopic microdiscectomy. None of the patients had had a previous operation on the low back, and all had failed to respond to nonoperative measures. Analysis of the outcomes of both procedures was based on the patient's self-evaluation before and after the operation, the preoperative and postoperative clinical findings, and the patient's ability to return to a functional status. The patients were followed for nineteen to forty-two months postoperatively.
                On the basis of the patient's preoperative and postoperative self-evaluation, the findings on physical examination, and the patient's ability to return to work or to normal activity, twenty-eight patients (93 percent) in Group 1 and twenty-nine patients (97 percent) in Group 2 were considered to have had a satisfactory outcome. The mean duration of postoperative disability before the patients were able to return to work was considerably longer in Group 1 than in Group 2 (forty-nine compared with twenty-seven days). The patients in Group 1 used narcotics for a longer duration postoperatively. No neurovascular complications or infections were encountered in either group.
                Although the rate of satisfactory outcomes was approximately the same in both groups, the patients who had had an arthroscopic microdiscectomy had a shorter duration of postoperative disability and used narcotics for a shorter period. These findings suggest that arthroscopic microdiscectomy may be useful for the operative treatment of specific symptoms, including radiculopathy, that are caused by lumbar disc herniation, provided that patients are properly selected--that is, they must have a herniated disc at a single level as confirmed on imaging studies, have failed to respond to nonoperative management, have no evidence of spinal stenosis, and have a herniation not exceeding one-half of the anteroposterior diameter of the spinal canal. Moreover, the surgeon must be familiar with this technique and must have received training in its use. There is an increasing drive to make nursing care evidence-based. High quality evidence from systematic reviews relevant to postoperative pain relief exists, yet pain after surgery remains poorly controlled for many patients. This study aimed to assess whether implementing evidence-based pain management improved postoperative pain outcomes. Pain on a 0-10 scale was the primary outcome and analgesic consumption a secondary outcome. A baseline audit was undertaken on four surgical wards to establish whether there was a need for the study. A randomized-controlled trial was then designed to assess the effects of implementing an evidence-based approach to postoperative pain management. The four wards were randomized to receive the intervention or act as a control. Outcomes were assessed 3 months after the intervention on both intervention and control wards. The intervention (implementation of an oral analgesic algorithm derived from systematic reviews) was then implemented on the control wards and outcomes reassessed after 3 months on the control wards. The intervention was designed using an evidence-based approach to effective implementation. Four interactive sessions covered: (1) detailed feedback of baseline data and discussion (utilizing audit and feedback), (2) why systematic reviews, analgesic league tables and choice of drugs to develop an analgesic algorithm (see Figure 1), (3) principles of evidence based health care (EBHC), including critical appraisal and (4) facilitation and change workshop. The findings revealed no significant differences in pain level or drug use between the intervention and control wards. However, the control wards also changed during the control period. Possible explanations for this are discussed. When looking at changes compared with baseline, both intervention and control wards increased their use of algorithm drugs and reduced use of non-algorithm drugs during the study. No effects were found on pain in the intervention wards. Pain ratings at rest since surgery, on movement since surgery and worst pain on movement were significantly reduced compared with baseline in the control wards. Although there are many pressures to utilize a randomized-controlled trial study design in the culture of evidence-based health care, there will be times, especially when implementing complex changes in practice that other types of design should be considered. The purpose of this study was to determine the clinical efficacy of manual therapy interventions for relieving the signs and symptoms of carpal tunnel syndrome (CTS) by comparing 2 forms of manual therapy techniques: Graston Instrument-assisted soft tissue mobilization (GISTM) and STM administered with the clinician hands.
                The study was a prospective comparative research design in the setting of a research laboratory. Volunteers were recruited with symptoms suggestive of CTS based upon a phone interview and confirmed by electrodiagnostic study findings, symptom characteristics, and physical examination findings during an initial screening visit. Eligible patients with CTS were randomly allocated to receive either GISTM or STM. Interventions were, on average, twice a week for 4 weeks and once a week for 2 additional weeks. Outcome measures included (1) sensory and motor nerve conduction evaluations of the median nerve; (2) subjective pain evaluations of the hand using visual analog scales and Katz hand diagrams; (3) self-reported ratings of symptom severity and functional status; and (4) clinical assessments of sensory and motor functions of the hand via physical examination procedures. Parametric and nonparametric statistics compared treated CTS hand and control hand and between the treatment interventions, across time (baseline, immediate post, and at 3 months' follow-up).
                After both manual therapy interventions, there were improvements to nerve conduction latencies, wrist strength, and wrist motion. The improvements detected by our subjective evaluations of the signs and symptoms of CTS and patient satisfaction with the treatment outcomes provided additional evidence for the clinical efficacy of these 2 manual therapies for CTS. The improvements were maintained at 3 months for both treatment interventions. Data from the control hand did not change across measurement time points.
                Although the clinical improvements were not different between the 2 manual therapy techniques, which were compared prospectively, the data substantiated the clinical efficacy of conservative treatment options for mild to moderate CTS. To assess the clinical effectiveness of surgical stabilisation (spinal fusion) compared with intensive rehabilitation for patients with chronic low back pain.
                Multicentre randomised controlled trial.
                15 secondary care orthopaedic and rehabilitation centres across the United Kingdom.
                349 participants aged 18-55 with chronic low back pain of at least one year's duration who were considered candidates for spinal fusion.
                Lumbar spine fusion or an intensive rehabilitation programme based on principles of cognitive behaviour therapy.
                The primary outcomes were the Oswestry disability index and the shuttle walking test measured at baseline and two years after randomisation. The SF-36 instrument was used as a secondary outcome measure.
                176 participants were assigned to surgery and 173 to rehabilitation. 284 (81%) provided follow-up data at 24 months. The mean Oswestry disability index changed favourably from 46.5 (SD 14.6) to 34.0 (SD 21.1) in the surgery group and from 44.8 (SD14.8) to 36.1 (SD 20.6) in the rehabilitation group. The estimated mean difference between the groups was -4.1 (95% confidence interval -8.1 to -0.1, P = 0.045) in favour of surgery. No significant differences between the treatment groups were observed in the shuttle walking test or any of the other outcome measures.
                Both groups reported reductions in disability during two years of follow-up, possibly unrelated to the interventions. The statistical difference between treatment groups in one of the two primary outcome measures was marginal and only just reached the predefined minimal clinical difference, and the potential risk and additional cost of surgery also need to be considered. No clear evidence emerged that primary spinal fusion surgery was any more beneficial than intensive rehabilitation. This study investigated the relative effects of vestibular rehabilitation (VR) and social reinforcement (SR) on recovery following ablative vestibular surgery. Twenty-four subjects were randomly assigned to three treatment groups of either VR with SR, VR without SR, or general range of motion (ROM) exercises with SR. Outcome measures included equilibrium scores in dynamic posturography, asymmetry index in rotation testing, motion sensitivity quotient (MSQ), and dizziness handicap inventory (DHI). A multiple comparison of the overall outcome measures showed no significant differences in group performance over an 8-week period. When individual outcome measures were compared, MSQ and DHI results at the end of the 8-week treatment period revealed less motion sensitivity and dizziness handicap in groups who received VR, with or without SR, as compared with the group who received ROM exercises. These results suggest that after a vestibular injury most patients can effectively utilize central compensation mechanisms to recover from such an injury, regardless of the type of therapeutic intervention used. On the other hand, the reduction in motion sensitivity and dizziness handicap for patients who received VR could indicate a more rapid and complete recovery for these patients. This investigation is continuing as a long-term follow-up study to determine whether there are any long-term benefits in participating in a VR program. Preoperative anxiety and physical unfitness have been shown to have adverse effects on recovery from cardiac surgery. This study involving cardiac surgery patients was primarily aimed at assessing the feasibility of delivering physical conditioning and stress reduction programs within the public hospital setting. Secondary aims were to evaluate the effect of these programs on quality of life (QOL), rates of postoperative atrial fibrillation (AF) and length of stay (LOS) in hospital.
                Elective patients scheduled for coronary artery bypass graft and/or valve surgery at a public hospital in Melbourne, Australia were enrolled. Patients were randomized to receive either holistic therapy (HT) or usual care (UC). HT consisted of a series of light physical exercise sessions together with a mental stress reduction program administered in an outpatient setting for the first two weeks after placement on the waiting list for surgery. A self-administered SF-36 questionnaire was used to measure QOL and hospital records to collect data on LOS and rate of postoperative AF.
                The study population comprised 117 patients of whom 60 received HT and 57 received UC. Both programs were able to be delivered within the hospital setting but ongoing therapy beyond the two week duration of the program was not carried out due to long waiting periods and insufficient resources. HT, as delivered in this study, compared to UC did not result in significant changes in QOL, LOS or AF incidence.
                Preoperative holistic therapy can be delivered in the hospital setting, although two weeks is insufficient to provide benefits beyond usual care on QOL, LOS or postoperative AF. Further research is now required to determine whether a similar program of longer duration, or targeted to high risk patients can provide measurable benefits.
                This trial was conducted as part of a larger study and according to the principles contained in the CONSORT statement 2001. The purpose of this randomized trial was to assess the clinical evolution after carpal tunnel release in subjects with long-term carpal tunnel syndrome. The evaluation criteria were symptom occurrence, motor performance, and delay in returning to work. A total of 100 subjects were assessed four times (prior to surgery, and 12 days, 1 month, and 3 months after surgery) using the Boston carpal tunnel questionnaire, the nine-hole peg test (NHPT), and the Jebsen-Taylor test (JTT). Subjects were randomized to a rehabilitation program or to a progressive home exercise program. No difference in symptom occurrence between the two groups was detected after 1 and 3 months. One month after surgery, only patients in the first group showed motor dexterity improvement according to NHPT and JTT scores. At the 3-month follow-up, the two groups did not differ but the group undergoing rehabilitation showed a shorter return-to-work interval. A rehabilitation approach after hand surgery is clinically relevant to accelerate recovery but neither modifies functional recovery nor reduces symptom occurrence.
                Copyright 2000 John Wiley & Sons, Inc. A prospective randomized controlled trial of exercise therapy in patients who underwent microdiscectomy for prolapsed lumbar intervertebral disc. Results of a pilot study are presented.
                To determine the effects of a postoperative exercise program on pain, disability, psychological status, and spinal function.
                Microdiscectomy is often used successfully to treat prolapsed lumbar intervertebral disc. However, some patients do not have a good outcome and many continue to have low back pain. The reasons for this are unclear but impairment of back muscle function due to months of inactivity before surgery may be a contributing factor. A postoperative exercise program may improve outcome in such patients.
                Twenty patients who underwent lumbar microdiscectomy were randomized into EXERCISE and CONTROL groups. After surgery, all patients received normal postoperative care that included advice from a physiotherapist about exercise and a return to normal activities. Six weeks after surgery, patients in the EXERCISE group undertook a 4-week exercise program that concentrated on improving strength and endurance of the back and abdominal muscles and mobility of the spine and hips. Assessments of spinal function were performed in all patients during the week before surgery and at 6, 10, 26, and 52 weeks after. The assessment included measures of posture, hip and lumbar mobility, back muscle endurance capacity and electromyographic measures of back muscle fatigue. On each occasion, patients completed questionnaires inquiring about pain, disability and psychological status.
                Surgery improved pain, disability, back muscle endurance capacity and hip and lumbar mobility in both groups of patients. After the exercise program, the EXERCISE group showed further improvements in these measures and also in electromyographic measures of back muscle fatigability. All these improvements were maintained 12 months after surgery. The only further improvement showed by the CONTROL group between 6 and 52 weeks was an increase in back muscle endurance capacity.
                A 4-week postoperative exercise program can improve pain, disability, and spinal function inpatients who undergo microdiscectomy. [Key words: electromyogram median frequency, exercise therapy, intervertebral disc prolapse, microdiscectomy, randomized controlled trial, spinal function. This study evaluated the effectiveness of a new rehabilitation service, compared with existing services, for carers of people with traumatic brain injury (TBI). Subjects were 96 adult carers of people consecutively admitted to two local hospitals. They were assigned to one of three groups: Early new service (pre-discharge); Late new service (post-discharge); or a Control condition (existing services only). Individual randomization was not possible and randomization by hospital site was rejected because of demographic and clinical differences between sites. Group assignment was determined by a pre-specified timetable which alternated between hospitals. Two outcomes were compared at 6 months post-injury: carers' emotional distress and how well-informed they felt about TBI and available resources. Analyses adjusting for potential confounding factors confirmed a clinically plausible superior outcome for both intervention groups compared to the control group. However, these differences did not obtain statistical significance (p > or = 0.01). Several reasons for these findings are discussed, including the novelty of the new service and methodological issues such as statistical power. Longer term follow-up studies are required as psychological sequelae and, therefore, the need for intervention is known to increase with time and may not be most apparent during the first 6 months. Deterioration in exercise tolerance and impairment in quality of life (QoL) are common consequences of lobectomy. This study evaluates additional exercise and strength training after lung resection on QoL, exercise tolerance and muscle strength. Fifty-three (28 male) patients attending thoracotomy for lung cancer, mean age, range 64 (32-82) years; mean pack years (SD) 31.9 (26.8); BMI 25.6 (4.2); FEV1 2.0 (0.7) l were randomised to control (usual care) or intervention (twice daily training plus usual care). After discharge the intervention group received monthly home visits and weekly telephone calls, the control group received monthly telephone calls up to 12 weeks. Assessment pre-operatively, 5 day and 12 weeks post-operatively consisted of quadriceps strength using magnetic stimulation, 6 Minute Walking Distance (6MWD) and QoL-EORTC-QLQ-LC13. QoL was unchanged over 12 weeks; 6MWD showed significant deterioration at 5 days post-operatively compared with pre-operatively, mean difference (SD)-131.6 (101.8) m and -128.0 (90.7) m in active and control groups respectively (p=0.89 between groups) which returned to pre-operative levels by 12 weeks in both groups. Quadriceps strength over the 5 day in-patient period showed a decrease of -8.3 (11.3) kg in the control group compared to increase of 4.0 (21.2) kg in the intervention group (p=0.04 between groups). Strength training after thoracotomy successfully prevented the fall in quadriceps strength seen in controls, however, there was no effect on 6MWD or QoL. 6MWD returned to pre-operative levels by 12 weeks regardless of additional support offered.

                A double-blind, randomized, parallel group design was used. The intervention group were offered comprehensive, multidisciplinary inpatient rehabilitation at the Haslev MS Hospital for an average of 35.5 days, while the control group received no treatment related to the study. All patients were examined in their homes twice with a 10-week interval. The rehabilitation of the intervention group started 2-3 weeks after the first examination and ended 2-3 weeks before the second examination. Impairment was assessed by the Multiple Sclerosis Impairment Scale and the Expanded Disability Status Scale. Disability was assessed by means of Guy's Neurological Disability Scale. Two specific scales were used to assess upper limb function and ambulation: The Nine-Hole Peg Test and timed 10-metre walking. Patients' own perception of bodily pain, bladder symptoms, spasticity, fatigue, impaired walking and transfers were recorded using visual analogue scales. Finally, quality of life was assessed using the Life Appreciation and Satisfaction Questionnaire and the Functional Assessment in Multiple Sclerosis.
                Two hundred and thirty-three patients were screened and of those 38 were included for treatment and 52 as controls.
                We found no statistically significant differences between the two groups in any of the outcome measures.
                Although the study was underpowered, the negative outcome exposes the difficulties in quantitative analyses of the efficacy of multidisciplinary rehabilitation, which is liable to confounding factors such as variation in the indication for treatment, in the placebo effect, and in the reliability and responsiveness of the outcome measures. Prospective, randomized controlled trial.
                To examine the effects of a 4-week rehabilitation program for chronic ankle instability (CAI) on postural control and lower extremity function.
                CAI is associated with residual symptoms, performance deficits, and reinjury. Managing CAI is challenging and more evidence is needed to guide effective treatment.
                Subjects with unilateral CAI were randomly assigned to the rehabilitation (CAI-rehab, n=16) or control (CAI-control, n=13) group. Subjects without CAI were assigned to a healthy group (n=19). Baseline testing included the (1) center of pressure velocity (COPV), (2) star excursion balance test (SEBT), and (3) Foot and Ankle Disability index (FADI) and FADI-Sports Subscale (FADI-Sport). The CAI-rehab group completed 4 weeks of rehabilitation that addressed range of motion, strength, neuromuscular control, and functional tasks. After 4 weeks, all subjects were retested. Nonparametric analyses for group differences and between-group comparisons were performed.
                Subjects with CAI demonstrated deficits in postural control and SEBT reach tasks of the involved limb compared to the uninvolved limb and reported functional deficits of the involved limb compared to healthy subjects. Following rehabilitation, the CAI-rehab group had greater SEBT reach improvements on the involved limb than the other groups and greater improvements in FADi and FADI-Sport scores.
                These results demonstrate postural control and functional limitations exist in individuals with CAl. In addition, rehabilitation appears to improve these functional limitations. Finally, there is evidence to suggest the SEBT may be a good functional measure to monitor change after rehabilitation for CAI. Evaluation of multidisciplinary community based outreach rehabilitation after severe traumatic brain injury (TBI).
                A randomised controlled trial compared outreach treatment (mean of two sessions a week for 27.3 (SD 19.1) weeks) in community settings such as participants' homes, day centres, or workplaces, with provision of written information detailing alternative resources. Follow up for an average of 24.8 months after initial allocation was by a blinded independent assessor. Participants were aged 16-65, had sustained severe TBI between 3 months and 20 years previously, and had no other neurological conditions. Of 110 initially allocated, 48 outreach and 46 information participants were successfully followed up. Primary outcome measures (Barthel index (BI) and the brain injury community rehabilitation outcome-39 (BICRO-39)) focused on levels of activity and participation. Secondary measures were the functional independence measure and the functional assessment measure (FIM+FAM) and, in a subgroup of 46 participants, the hospital anxiety and depression scale. Analyses were non-parametric.
                outreach participants were significantly more likely to show gains on the BI and the BICRO-39 total score and self organisation and psychological wellbeing subscales. There were likewise strong trends (p<0.10) for BICRO personal care and mobility, and on the FIM+FAM for personal care and cognitive functions. Differential improvements were not seen for indices of socializing, productive employment, anxiety, or depression. Median changes on individual subscales were small, reflecting the diversity of the clinical population; however, 40% of outreach but only 20% of information participants made a clinically significant improvement of 2+ points on at least one BICRO-39 scale. Time since injury was unrelated to the magnitude of gains.
                This is the first RCT of multidisciplinary community rehabilitation after severe TBI, and suggests that even years after injury it can yield benefits which outlive the active treatment period. To assess the efficacy, as well as the long term duration, of a new procedure for the rehabilitation of visuospatial neglect in patients with right hemisphere stroke.
                Patients with right unilateral hemispheric damage identified with neglect were assigned to a treatment (T+) or a control (T-) group. The treatment consisted in abolishing all visual inputs from the right hemispace for one week by means of specially devised hemiblinding goggles. Patients' visuospatial abilities were tested and compared between groups immediately after the week of treatment. Both groups were further assessed one week after treatment suspension for evaluation of long term beneficial effects.
                Following the treatment, a substantial amelioration of visuospatial neglect symptoms was selectively observed in the T+ group. In contrast, untreated patients showed only weak signs of recovery. Most important, the amelioration obtained in the T+ group of patients was not ephemeral, being significantly maintained after a further period of one week, even after suspension of the treatment.
                The protracted efficacy of the proposed "hemiblinding technique" may have important implications for the recovery of visuospatial neglect and may be a very promising tool for investigating both the cognitive and the neural basis of neglect rehabilitation. In publicly funded health care systems, a waiting period for such services as coronary artery bypass graft surgery (CABG) is common. The possibility of using the waiting period to improve patient outcomes should be investigated.
                To examine the effect of a multidimensional preoperative intervention on presurgery and postsurgery outcomes in low-risk patients awaiting elective CABG.
                Randomized, controlled trial.
                A regional cardiovascular surgery center in a tertiary care hospital, southwestern Ontario, Canada.
                249 patients on a waiting list for elective CABG whose surgeries were scheduled for a minimum of 10 weeks from the time of study recruitment.
                During the waiting period, the treatment group received exercise training twice per week, education and reinforcement, and monthly nurse-initiated telephone calls. After surgery, participation in a cardiac rehabilitation program was offered to all patients.
                Postoperative length of stay was the primary outcome. Secondary outcomes were exercise performance, general health-related quality of life, social support, anxiety, and utilization of health care services.
                Length of stay differed significantly between groups. Patients who received the preoperative intervention spent 1 less day [95% CI, 0.0 to 1.0 day] in the hospital overall (P = 0.002) and less time in the intensive care unit (median, 2.1 hours [CI, -1.2 to 16 hours]; P = 0.001). During the waiting period, patients in the intervention group had a better quality of life than controls. Improved quality of life continued up to 6 months after surgery. Mortality rates did not differ.
                The waiting period for elective procedures, such as CABG, may be used to enhance in-hospital and early-phase recovery, improving patients' functional abilities and quality of life while reducing their hospital stay. The purpose of this trial was to determine the effectiveness of advanced practice nursing support on cardiac surgery patients' during the first 5 weeks following hospital discharge. Patients ( N = 200) were randomly allocated to two groups: (a) an intervention group who received telephone calls from an advanced practice nurse (APN) familiar with their clinical condition and care needs, twice during the first week following discharge then weekly thereafter for 4 weeks, and (b) a usual care group. Measures of health-related quality of life (HRQL), symptom distress, satisfaction with recovery care, and unexpected health care contacts were obtained at 5 weeks following discharge. There were no significant group differences in HRQL, unexpected contacts with the health care system, or symptom distress. The provision of APN support via telephone followup after cardiac surgery is feasible. However, further randomized trials of single and multicomponent APN interventions are needed to prove effectiveness.
There is limited and, in general, low quality evidence for the benefit of the reviewed interventions. People who have had CTS surgery should be informed about the limited evidence of the effectiveness of postoperative rehabilitation interventions. Until the results of more high quality trials that assess the effectiveness and safety of various rehabilitation treatments have been reported, the decision to provide rehabilitation following CTS surgery should be based on the clinician's expertise, the patient's preferences and the context of the rehabilitation environment. It is important for researchers to identify patients who respond to a certain treatment and those who do not, and to undertake high quality studies that evaluate the severity of iatrogenic symptoms from the surgery, measure function and return-to-work rates, and control for confounding variables.
