ABSTRACT
There are several pathologies related to the patellofemoral joint, in which the patellofemoral syndrome is one of the most common and challenging to treat. The patellofemoral syndrome results from a malalignment of the knee extensor mechanism. The purpose of our study was to describe and compare EMG responses of the vastus medialis and vastus lateralis muscles while walking up and down stairs and other clinical and functional responses in PFS subjects before and after a physical therapy intervention. Eleven subjects were studied and divided in two groups: six subjects with clinically diagnosed patellofemoral syndrome and five healthy control subjects. Subjects were evaluated by a functional and biomechanical evaluation protocol: postural evaluation, pain and knee function evaluation, and electromyographic activity of vastus medialis and lateralis muscles while walking up and down a staircase. Results showed higher efficiency of the vastus medialis muscle in carrying out eccentric exercises and increased muscle activity in both the vastus medialis and vastus lateralis muscles while climbing stairs after physical therapy treatment. We were able to identify an improvement in postural alignment of lower limb muscles and knee functionality among patellofemoral syndrome group subjects after treatment.

A síndrome femoropatelar (SFP), patologia de difícil tratamento, decorre de um desiquilíbrio das forças que incidem sobre a patela durante seu movimento normal; frequentemente não se obtém alívio total da dor. Este estudo visou avaliar o efeito de tratamento fisioterapêutico em seis sujeitos com SFP.
Patellofemoral syndrome (PFS), a challenging pathology to treat wherein full pain relief is rarely obtained - results from force imbalance exerted on the patella during its normal movement. This study assessed the effect of a physical therapy treatment on six...
