Short-term Effect of Patellar Taping and Electromyographic Biofeedback Strength Training on Quadriceps Strength

Study Overview
=================
Brief Summary
-----------------
Patellofemoral pain syndrome is one of the most common young adult female complaints, caused by changes in the patellofemoral joint's physical and biomechanical properties. This study compared the Short-term effects of patellar taping and electromyographic-biofeedback (EMG-BF) guided maximum voluntary isometric contraction of quadriceps muscle strengthening at 900 or 600 knee angles on quadriceps strength and functional performance in a female patient with patello-femoral pain syndrome (PFPS)

Official Title
-----------------
Short-term Effect of Patellar Taping and Electromyographic Biofeedback Strength Training on Quadriceps Strength and Functional Performance in Female With Patellofemoral Pain Syndrome

Conditions
-----------------
Patello Femoral Syndrome

Intervention / Treatment
-----------------
