OBJECTIVES: To examine the association between self-efficacy, social support, and
fear of movement with physical activity and function at baseline and after 12
weeks of physical therapy. DESIGN: Nonrandomized cohort study, repeated-measures
design. SETTING: Outpatient rehabilitation clinic within the general community.
PARTICIPANTS: Adults (N=49) undergoing outpatient physical therapy for total knee
replacement (TKR). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES:
Self-efficacy for exercise (SEE), fear of movement, leisure-time physical
activity (LTPA), 6-minute walk test (6MWT), and Knee Outcome Survey-Activities of
Daily Living Scale (KOS-ADLS) were assessed at baseline and 12 weeks. RESULTS:
Mean functional change scores significantly increased at 12 weeks for the 6MWT
(95% confidence interval [CI], 42.3-106.2), KOS-ADLS (95% CI, 12.7-23.3), and
LTPA (95% CI, 6.5-26.1).
Self-efficacy and fear of movement were not
significantly associated with function at baseline or 12 weeks. Participants with
lower SEE had 6 fewer metabolic equivalents per week of improvement in LTPA than
those with high self-efficacy (95% CI, -27.9 to 14.8), and those with high fear
of movement had 26.1m less improvement in the 6MWT than those with low fear of
movement (95% CI, -42.2 to 94.5). Most participants reported having no family or
peer support for exercise. CONCLUSIONS: Physical therapy for TKR improves
physical function and self-reported physical activity. High fear of movement and
low SEE may be associated with less improvement in physical activity and function over time.
