Comparação entre exercícios de fortalecimento muscular em cadeia cinética aberta e cadeia cinética fechada em indivíduos com síndrome patelofemoral

Abstract

The patellofemoral pain syndrome (PFPS) is a condition that affects young adults (15-35 years), mostly female and have a multifactorial etiology. It is characterized by diffuse pain or previous retropatellar source insidious and consists of 25% of orthopedic diagnoses. This literature review aims to determine and compare the exercises performed in open kinetic chain (OKC) and closed (CKC) in the treatment of patellofemoral pain syndrome (PFPS). The databases were searched LILACS, MEDLINE, SciELO and PeDro, using the descriptors open kinetic chain, closed kinetic chain, exercise, patellofemoral syndrome, patellofemoral dysfunction, isolated and / or associated. The outcome measures were pain, muscle strength, flexibility and functional performance. Eight articles met the inclusion criteria. The results showed that OKC and CKC exercises provide pain relief, improved functional capacity, greater muscle activation of the knee extensors and flexors. Different positions of the trunk, the angle of knee flexion, rotation of the hip or tibia and incremental load are variables that must be observed when prescribing exercise.
