ABSTRACT
Patellofemoral Pain (PFP) is one of the most frequent musculoskeletal dysfunctions in the knee, which mainly affects the female population and whose treatment is controversial. Objective: To analyze the effects of neuromuscular electrical stimulation in the vastus medialis obliquus (VMO) and gluteus medius (GM) associated with an eight-week intervention protocol on electromyographic activity (EMG), muscle performance, self-reported functionality and pain of women with DFP. Methods: This is a randomized, blinded trial in which 60 women, aged 18-30 years, will be randomized into 2 groups: Stimulation and Exercise Group (SEG) - will perform an exercise protocol associated with stimulation in the VMO and GM muscles. Exercises Group (ExG) - will perform the same protocol of exercises of the previous group, however, without association with neuromuscular electrical stimulation. The intervention will occur twice a week for eight weeks. All volunteers will be submitted to the evaluation of the electromyographic activity of the VMO, the GM and the vastus lateralis, the dynamometric parameters, the intensity of the pain and the functionality, in four moments: 72h hours before the beginning of the intervention; after 4 weeks of intervention (4 weeks Evaluation); after 8 weeks of intervention (8 weeks Evaluation); after 16 weeks from the start of the intervention (eight weeks after the end of the protocol- Residual Evaluation). In this way, we will investigate the applicability of the proposed trial with the use of neuromuscular electrical stimulation and identify the effects of this resource in the treatment of PFP.
