简要总结
The purpose of this study is to investigate the effects of a Functional Stabilization training program (FST) and a comprehensive corrective exercise program in PF pain and DKV.
详细描述
PF pain impairs performance and quality of life and can predispose individuals to early PF osteoarthritis and Dynamic knee valgus has been identified as a modifiable risk factor for PF pain and serious knee injury .
Current rehabilitation strategies show mixed results. Solo hip strengthening programs may not correct Dynamic knee valgus. While both Functional Stabilization training (FST) and comprehensive corrective programs (CCEP) show potential benefits, direct comparisons are lacking. The FST suggested superior outcomes with functional training, but it did not specifically target DKV. Conversely, the CCEP demonstrated kinematic improvements, but included asymptomatic participants and lacked patient reported outcomes.
By directly comparing Functional Stabilization training (FST) with the CCEP, this study aims to provide clinicians with evidence based guidance on the most effective exercise strategy for improving lower limb kinematics and reducing pain. The findings could inform best practice guidelines and enhance outcomes.

研究组 & 干预措施
Standard Care (SC)
Standard care exercise program for patellofemoral pain. Participants receive 24 supervised sessions (3 sessions/week for 8 weeks), ~45-60 minutes/session." (If you want 1 extra line: "Exercises follow a conventional PFP program based on Baldon et al.")
干预措施: Standard Care Exercise Program (SC) (Behavioral)
Functional Stabilization Training (FST)
Functional stabilization/neuromuscular training to optimize movement patterns and dynamic alignment. 24 supervised sessions (3/week for 8 weeks), ~45-60 minutes/session. Includes warm-up/cool-down (~15 min) and ~45 min exercises. Intensity/progression increases every 2 weeks; exercises progress from ~2 sets (10-20 reps) with ~5-sec isometric holds to ~3 sets of ~12 reps with ~10-sec holds and added external load (weights/elastic resistance)
干预措施: Functional Stabilization Training (FST) (Behavioral)
Comprehensive Corrective Exercise Program (CCEP)
Comprehensive corrective exercise program targeting strength, flexibility, neuromuscular control, and alignment across the kinetic chain for dynamic knee valgus. 24 supervised sessions (3/week for 8 weeks), ~45-60 minutes/session. Three phases: weeks 1-2 sensorimotor/non-weight-bearing alignment + feedback + isometrics; weeks 3-6 progressive weight-bearing with increased load/complexity and emphasis on co-contraction/reciprocal activation; weeks 7-8 functional tasks to maintain gains and challenge multi-planar control. Visual/verbal/tactile feedback provided; progression only with correct technique

结局指标
主要结局
Peak Knee Abduction (Valgus) Angle (3D motion analysis)
时间窗: Baseline and 8 weeks
Change in peak knee abduction (valgus) angle of the stance limb measured using a 3D motion capture system (Vicon) during functional tasks (single-leg squat and drop/vertical jump landing). Lower values indicate reduced dynamic knee valgus.
Hip and Pelvis Kinematics (3D motion analysis)
时间窗: Baseline and 8 weeks
Change in peak hip adduction, peak hip internal rotation, contralateral pelvic drop, and trunk lateral lean during the functional tasks measured by 3D motion capture.
次要结局
- Kujala Patellofemoral Scale (KPS)(Baseline and 8 weeks)
