Objective: A 12-week trial was conducted to examine the feasibility and preliminary effects of a biopsychosocial model-based self-management program (SMP) for knee pain on physical activity and sedentary behavior in patients with knee pain.
Methods: All forty-four patients with knee pain (age, 72.4 years; 93% female) received physical therapy and were divided into an intervention group willing to participate in SMP (n=24) and a control group not willing to participate (n=20). A SMP of nine 60-minute on pain, arthritis and lifestyle were provided over 12 weeks by physical therapists. Moderate-to-vigorous intensity physical activity (MVPA) and sedentary behavior (SB) time were assessed using a questionnaire at baseline and week 12.
Results: No adverse events occurred during the intervention. Seven of the 44 patients dropped out of the study, with a mean attendance rate of 78.8% in the SMP. The between-group difference in MVPA (METs・minute/weeks) change did not reach statistical significance, but the reduction in SB time (minutes/day) was significantly greater in the intervention group than in the control group (Mean difference: –190, 95%CI –262, –116. Cohen's d = 0.78).
Conclusion: Our study suggests that adding SMP to physical therapy was feasible and effective in reducing SB time in patients with knee pain.
