What this trial studies
This research examines the connection between limited ankle dorsiflexion and its impact on single limb squats in individuals suffering from patellofemoral pain. Participants will be randomly assigned to either an experimental group, which will receive interventions aimed at increasing dorsiflexion, or a minimal intervention group that will engage in light activities. The study will involve measuring dorsiflexion range of motion, hip abductor strength, and performance on the Lateral Step Down test using motion capture technology. The goal is to understand how improving ankle mobility may influence knee pain and function during specific movements.
Who should consider this trial
Good fit: Ideal candidates are females aged 18-59 with a history of active patellofemoral pain for at least 6 months and limited ankle dorsiflexion.
Not a fit: Patients with a history of musculoskeletal surgery, current knee effusion, or significant resting pain may not benefit from this study.
Why it matters
Potential benefit: If successful, this study could lead to improved treatment strategies for individuals with patellofemoral pain by enhancing their functional movement capabilities.
How similar studies have performed: While the specific approach may be novel, similar studies have indicated that addressing ankle mobility can positively affect knee function and pain.
