The Comparison of Hip and Knee Focused Exercises Versus Hip and Knee Focused Exercises With the Use of Blood Flow Restriction Training in Adults With Patellofemoral Pain

Hip and Knee strengthening exercises are implemented in Patellofemoral Pain (PFP) rehabilitation but exercising in high loads to achieve muscle changes in strength may lead to increased patellofemoral joint stress. Low load training with Blood Flow Restriction (BFR) may allow for exercise strength benefits to proximal and distal muscles with reduced joint stress and by promoting hypoalgesia. The purpose of this study is to compare hip and knee focused exercises with and without BFR training in adults with PFP. The main outcome of this study is function ability which will be measured with the Kujala Anterior Knee pain Scale translated in the Greek language at four weeks post intervention and at two months follow up. Our null hypothesis is that there will be no difference between groups for primary and secondary outcomes measured at four weeks and two months post intervention.
