Stabilization vs Corrective Exercise in PFP

Functional Stabilization Training VS Comprehensive Corrective Exercises on Lower Limb Kinematics in Patellofemoral Pain and Dynamic Knee Valgus

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.

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.
