简要总结
Patellofemoral pain (PFP) is the most common running-related overuse injury, with prevalence up to 17% among runners. Increased patellofemoral joint stress (PFJS) is a major biomechanical contributor to PFP. Traditional strengthening exercises improve function but do not alter running biomechanics. Gait retraining, particularly cadence modification, has been proposed as a promising approach to reduce PFJS and alleviate symptoms. However, evidence from randomized controlled trials remains limited. This study investigates whether wearable device-assisted gait retraining reduces pain, improves function, and modifies running biomechanics in female runners with PFP compared to education alone.

结局指标
主要结局
Visual Analogue Scale for Pain
时间窗: Baseline, Week 6, Week 18
The Visual Analogue Scale (VAS) is a validated, widely used instrument for assessing subjective pain intensity. It consists of a 10-centimeter horizontal line, with one end (0) representing "no pain" and the other end (10) representing "worst imaginable pain."

- Peak Knee Flexion Angle During Running(Baseline, Week 6)
- Ground Reaction Force During Running(Baseline, Week 6)
