Two weeks of wearing a knee brace compared to minimal intervention on kinesiophobia at 2 and 6-weeks in people with patellofemoral pain: A randomized controlled trial Academic Article uri icon

abstract

  • OBJECTIVE:To investigate the effect of a knee brace compared with minimal intervention on self-reported kinesiophobia and function, objective function, and physical activity level in people with patellofemoral pain (PFP). DESIGN:Single-blind randomized controlled trial (1:1), parallel. PARTICIPANTS:Individuals with PFP (N=50). MAIN OUTCOME MEASURES:Primary: kinesiophobia (Tampa Scale for Kinesiophobia). Secondary: self-reported function (Anterior Knee Pain Scale), physical activity level (International Physical Activity Questionnaire), and objective function (forward step-down test). Outcomes were assessed at baseline (T0), at the end of the intervention (2wk) (T1), and at 6 weeks after baseline (T2). INTERVENTION:Participants were randomly assigned to 1 of 2 interventions groups: (1) use of knee brace for 2 weeks during daily living, sports, or painful tasks (brace group) and (2) educational leaflet with information about PFP (leaflet group). RESULTS:The knee brace reduced kinesiophobia in people with PFP compared with minimal intervention with moderate effect size at T1=mean difference (95% CI) -5.56 (-9.18 to -1.93) and T2=-5.24 (-8.58 to -1.89). There was no significant difference in self-reported and objective function and physical activity level. CONCLUSIONS:The knee brace improved kinesiophobia immediately after intervention (at 2wk) and at 6-week follow-up in people with PFP compared with minimal intervention. A knee brace may be considered within clinically reasoned paradigms to facilitate exercise therapy interventions for people with PFP.
