Aims: Synthetize EMG findings in order to better understand the role of gluteal muscle activity in the aetiology, presentation and management of PFPS
Methods: SR 2 independent assessors, Downs and Black Quality Index25 and the PFPS diagnosis checklist. 10 studies included.
Results: Current research evaluating the association of gluteal muscle activity with PFPS is limited by an absence of prospective research. Moderate-to-strong evidence indicates that GMed muscle activity is delayed and of shorter duration during stair ascent and descent in individuals with PFPS. Additionally, limited evidence indicates that GMed muscle activity is delayed and of shorter duration during running, and GMax muscle activity is increased during stair descent.
Limitations: Quality too used, no blinding of assessors, low quality of included studies.
In practice: Assessing, targeting interventions toward hip muscles may have an impact on PFPS? However, the effects and effectiveness of such interventions is yet unknown.
