Physical therapists' use of therapeutic exercise for patients with clinical knee osteoarthritis in the United kingdom: in line with current recommendations?

ABSTRACT: Physical therapists have an important role in the management of clinical knee osteoarthritis (OA) through designing and supervising exercise programs. This study explored whether their current use of therapeutic exercise for patients with this condition is in line with recent recommendations.A cross-sectional survey was conducted with a random sample of chartered (licensed) physical therapists (N=2,000) practicing in the United Kingdom. This survey included a vignette describing a patient with clinical knee OA as well as clinical management questions relating to the respondents' use of therapeutic exercise.The questionnaire response rate was 58% (n=1,152), with 538 respondents stating they had treated a patient with clinical knee OA in the preceding 6 months. In line with recent recommendations, 99% of the physical therapists stated they would use therapeutic exercise for this patient population, although strengthening exercises were favored over aerobic exercises. Although nearly all physical therapists would monitor exercise adherence, only 12% would use an exercise diary. Seventy-six percent of physical therapists would provide up to 5 treatment sessions, and only 34% would offer physical therapy follow-up after discharge.The measure of physical therapists' current clinical practice was self-reported clinical behavior on the basis of a vignette. Although this is a valid measure of clinical behavior, in practice, physical therapists may use therapeutic exercise differently. There are disparities between physical therapists' current use of therapeutic exercise for clinical knee OA and recent recommendations. Identifying potential ways to overcome these disparities is an important step toward optimizing the outcome from therapeutic exercise for patients with clinical knee OA.

Project description:BACKGROUND:Practice guidelines emphasize the use of exercise and weight reduction as the first line of management for knee osteoarthritis (OA). However, less than half of the people with mild OA participate in moderate intensity physical activity. Given that physical activities have been shown to reduce pain, improve quality of life, and have the potential to reduce the progression of joint damage, many people with OA are missing the benefits of this inexpensive intervention. OBJECTIVE:The objectives of this study are (1) to develop a behavioral theory-informed Internet intervention called Osteoarthritis Physical Activity & Exercise Net (OPEN) for people with previously undiagnosed knee OA, and (2) to assess the efficacy of the OPEN website for improving physical activity participation through a proof-of-concept study. METHODS:OPEN was developed based on the theory of planned behavior. Efficacy of this online intervention is being assessed by an ongoing proof-of-concept, single-blind randomized controlled trial in British Columbia, Canada. We are currently recruiting participants and plan to recruit a total of 252 sedentary people with previously undiagnosed knee OA using a set of validated criteria. Half of the participants will be randomized to use OPEN and receive an OA education pamphlet. The other half only will receive the pamphlet. Participants will complete an online questionnaire at baseline, 3 months, and 6 months about their participation in physical activities, health-related quality of life, and motivational outcomes. In addition, we will perform an aerobic fitness test in a sub-sample of participants (n=20 per study arm). In the primary analysis, we will use logistic regression to compare the proportion of participants reporting being physically active at or above the recommended level in the 2 groups, adjusting for baseline measurement, age, and sex. RESULTS:This study evaluates a theory-informed behavioral intervention at a time when people affected with OA tend to be more motivated to adopt an active lifestyle (ie, at the early stage of OA). Our approach, which consisted of the identification of early knee OA followed immediately by an online intervention that directly targets physical inactivity, can be easily implemented across communities. CONCLUSIONS:Our online intervention directly targets physical inactivity at a time when the joint damage tends to be mild. If OPEN is found to be effective in changing long-term physical activity behaviors, it opens further opportunities to promote early diagnosis and to implement lifestyle interventions.

Project description:BackgroundTherapeutic exercise is a currently recommended nonpharmacological treatment for knee osteoarthritis (KOA). The optimal treatment dose (frequency or duration) has not been determined.ObjectiveTo examine dose-response relationships, minimal effective dose, and baseline factors associated with the timing of response from 2 exercise interventions in KOA.DesignSecondary analysis of a single-blind, randomized trial comparing 12-week Tai Chi and physical therapy exercise programs (Trial Registry #NCT01258985).SettingUrban tertiary care academic hospital PARTICIPANTS: A total of 182 participants with symptomatic KOA (mean age 61 years; BMI 32 kg/m2, 70% female; 55% white).MethodsWe defined dose as cumulative attendance-weeks of intervention, and treatment response as ≥20% and ≥50% improvement in pain and function. Using log-rank tests, we compared time-to-response between interventions, and used Cox regression to examine baseline factors associated with timing of response, including physical and psychosocial health, physical performance, outcome expectations, self-efficacy, and biomechanical factors.Main outcome measuresWeekly Western Ontario and McMasters Osteoarthritis Index (WOMAC) pain (0-500) and function (0-1700) scores.ResultsBoth interventions had an approximately linear dose-response effect resulting in a 9- to 11-point reduction in WOMAC pain and a 32- to 41-point improvement in function per attendance-week. There was no significant difference in overall time-to-response for pain and function between treatment groups. Median time-to-response for ≥20% improvement in pain and function was 2 attendance-weeks and for ≥50% improvement was 4-5 attendance-weeks. On multivariable models, outcome expectations were independently associated with incident function response (hazard ratio = 1.47, 95% confidence interval 1.004-2.14).ConclusionsBoth interventions have approximately linear dose-dependent effects on pain and function; their minimum effective doses range from 2-5 weeks; and patient perceived benefits of exercise influence the timing of response in KOA. These results may help clinicians to optimize patient-centered exercise treatments and better manage patient expectations.Level of evidenceII.
