The Effect of Patellar Taping and Isometric Strength Training on Quadriceps Strength with Patellofemoral Pain Syndrome.

The Influence of Patellar Taping Combined with Isometric Strength Training on Pain, Muscle Strength, and Functional Performance in Individuals with Patellofemoral Pain Syndrome.

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 combined with 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)
