Effectiveness of Gait Retraining in Female Runners With Patellofemoral Pain

The intervention is a wearable device-assisted gait retraining program designed specifically for female runners with patellofemoral pain (PFP). Unlike conventional physiotherapy or exercise-based interventions, this program integrates real-time biofeedback through a commercially available smartwatch and its mobile application. Participants are instructed to increase their step rate by 10% above their preferred cadence. The smartwatch provides auditory metronome cues and real-time cadence feedback to ensure accurate step-rate modification.

PFP education, load management strategies, symptom-based training modifications, and strengthening exercises.
