Eficácia do fortalecimento da musculatura do quadril na intensidade da dor, força muscular e função de indivíduos com síndrome da dor patelofemoral: uma revisão sistemática

Abstract

Background: Patellofemoral pain syndrome (PFPS) is a clinical condition characterized by retro or peripatellar pain in activities involving weight-bearing. Conservative treatments are recommended to reduce the pain intensity and physical limitations associated with the PFPS and its objective is the improvement of dynamic lower limb alignment by changing muscles properties. The objectives of this systematic review are (1) summarize the literature related to the hip muscle strengthening efficacy on pain intensity, muscle strength and patients function with PFPS, (2) assess the methodological quality of the selected studies. Methodology: A search for randomized clinical trials (RCT) was conducted in Google Scholar, MEDLINE / PubMed, PEDro, LILACS and SciELO databases. The reports should include volunteers with PFPS and investigate at least one of the following outcomes: pain, muscle strength and function. The studies should allow differentiating the effects of intervention for hip muscles strengthening compared to no intervention or other intervention. The methodological quality of studies was assessed by one rater using the Portuguese version (Brazil) of the Physiotherapy Evidence Database Scale (PEDro). Results: Seven RCT were included in this review. The articles showed positive results when reporting pain reduction in the group that underwent the hip muscles strengthening. The articles reported controversial results regarding muscle strength, which may have been influenced by the way the force was trained and then assessed. It was observed the improvement of the function in five studies included in this review. Conclusion: The hip muscle strengthening is important in the treatment of SPF, as it is effective in reducing pain intensity, increasing the hip muscles strength and improving the function of the patients. However, it is worth noting that the intervention should be always guided by the assessment findings and consider the patients specific dysfunctions.
