Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The patellofemoral pain syndrome (PFPS) is defined as a painful complaint in the anterior aspect of the knee, although peripatellar pain and / or retropatellar are also common. In general, conservative treatment is the initial option of choice for patients with PFPS, however, the lack of a specific causal factor makes it difficult to choose the best treatment so early. This way, the purpose of this study is investigate the effects of the quadriceps femoris strengthening versus hamstring stretching in patients with pattellofemoral pain.
