The effects of an exercise program for older adults with osteoarthritis of the hip. Primary care-based physical activity programs: effectiveness in sedentary older patients with osteoarthritis symptoms. Physical activity for osteoarthritis management: a randomized controlled clinical trial evaluating hydrotherapy or Tai Chi classes. The effects of a health educational and exercise program for older adults with osteoarthritis for the hip or knee.
. Evaluation of an 8-week exercise program with strength training and lifestyle advice for older adults with osteoarthritis (OA) of the hip. Outcome measures were pain, hip function, disability, quality of life (QOL), and body mass index (BMI).
                Inclusion criteria for this randomized controlled trial were: age >or=55 years, clinical diagnosis of OA according to American College of Rheumatology criteria, and living independently. Interview and physical data were collected at baseline, post-test, and followup (3 mo) by trained interviewers and physical therapists with validated instruments: Harris Hip Score, Sickness Impact Profile, Groningen Activity Restriction Scale, functional tests (walking, timed Up & Go, ascending and descending stairs, and toe reaching), and visual analog scales (pain and QOL). Data were analyzed on an intention-to-treat basis. Effect sizes were calculated.
                There were 109 participants (55 experimental, 54 controls). The 15 participants who dropped out were characterized by less tolerance to pain and younger age. The program had a positive effect on pain (moderate effect at post-test and small effect at followup), hip function (small effect at post-test), self-reported disability (small effect at followup), and the timed Up & Go test (small effect at followup). It did not affect QOL, other measures of observed disability, or BMI.
                The exercise program had positive effects on pain and hip function, which are important mediators of disability. This study fulfilled a need for older adults with hip OA and provides evidence of the benefit of exercise in the management of hip OA. This study examined, in a group of older patients, (a) the effectiveness of an invitation to participate in a program providing individualized physical activity advice in a primary care setting and (b) the changes in self-reported physical activity and symptoms in patients with osteoarthritis (OA).
                Healthy, sedentary community-dwelling men and women aged 60 years or more were invited to participate. Following random allocation, the intervention group received individualized physical activity advice at baseline and at 3, 6, and 12 months followup.
                Of the 299 people who satisfied the study's inclusion criteria, a subgroup of 69 people reported pain and stiffness of the hip or knee at baseline. These patients reported increases in frequency and time of walking and vigorous exercise (all P < 0.001), with no change to OA symptom scores (pain and stiffness), and a small decline in physical functioning was reported at 12 months followup in the control group only (P = 0.027). At the 12-month followup more intervention participants than control participants (P = 0.013) reported a greater intention to exercise.
                An offer of primary care-based physical activity advice, with an emphasis on the benefits for general health (rather than "treatment" for OA), will attract individuals with OA symptoms. Although the present study was unable to demonstrate intervention-control group differences for the majority of outcomes, intention to exercise did appear to be positively influenced. To determine whether Tai Chi or hydrotherapy classes for individuals with chronic symptomatic hip or knee osteoarthritis (OA) result in measurable clinical benefits.
                A randomized controlled trial was conducted among 152 older persons with chronic symptomatic hip or knee OA. Participants were randomly allocated for 12 weeks to hydrotherapy classes (n = 55), Tai Chi classes (n = 56), or a waiting list control group (n = 41). Outcomes were assessed 12 and 24 weeks after randomization and included pain and physical function (Western Ontario and McMaster Universities Osteoarthritis Index), general health status (Medical Outcomes Study Short Form 12 Health Survey [SF-12], version 2), psychological well-being, and physical performance (Up and Go test, 50-foot walk time, timed stair climb).
                At 12 weeks, compared with controls, participants allocated to hydrotherapy classes demonstrated mean improvements (95% confidence interval) of 6.5 (0.4, 12.7) and 10.5 (3.6, 14.5) for pain and physical function scores (range 0-100), respectively, whereas participants allocated to Tai Chi classes demonstrated improvements of 5.2 (-0.8, 11.1) and 9.7 (2.8, 16.7), respectively. Both class allocations achieved significant improvements in the SF-12 physical component summary score, but only allocation to hydrotherapy achieved significant improvements in the physical performance measures. All significant improvements were sustained at 24 weeks. In this almost exclusively white sample, class attendance was higher for hydrotherapy, with 81% attending at least half of the available 24 classes, compared with 61% for Tai Chi.
                Access to either hydrotherapy or Tai Chi classes can provide large and sustained improvements in physical function for many older, sedentary individuals with chronic hip or knee OA. Evaluation of a self-management program for patients with osteoarthritis (OA) of the hip or knee. The program, which consisted of 6 weekly sessions of 2 hours, included health education by a peer and physical exercises taught by a physical therapist.
                Randomized controlled trial. Inclusion criteria were diagnosis of OA of the hip or knee according to ACR clinical and radiographic criteria and age 55 to 75 years. Exclusion criteria: on waiting list for joint replacement. There were pretest, posttest, and followup (6 months) assessments. The experimental group consisted of 56 patients, the control group 49. Outcome variables were pain, quality of life, activity restrictions, knowledge about OA, self-efficacy, body mass index (BMI), and mobility measures. Attention was also paid to effects on health care utilization and lifestyle behavior.
                Significant MANOVA group x time effects (p < 0.05, one-sided) were found for pain, quality of life, strength of the left M. quadriceps, knowledge, self-efficacy, BMI, physically active lifestyle, and visits to the physical therapist. Most effects were moderate at posttest assessment and smaller at followup. No effects were found for range of motion and functional tasks.
                The program was reasonably effective, but more attention should be paid to proactive followup interventions and to the selection of participants.
The limited number and small sample size of the included RCTs restricts the confidence that can be attributed to these results. Adequately powered RCTs evaluating exercise programs specifically designed for people with symptomatic hip OA need to be conducted.
