简要总结
Objective this study is to analyze the effects of an intervention protocol with neuromuscular electrical stimulation in the vastus medialis obliquus and gluteus medius (GM) associated with exercises on electromyographic activity, muscle performance, self-reported functionality and pain of women with patellofemoral pain.
详细描述
This is a randomized, blinded trial in which 40 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 vastus medialis (VM) and gluteus medius (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 VM, 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; after 8 weeks of intervention; after 16 weeks from the start of the intervention (eight weeks after the end of the protocol). In this way, the investigators 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.

结局指标
主要结局
Knee function
时间窗: Change from baseline in knee function at 8 weeks.
Evaluation of knee function using the Anterior Knee Pain Scale, that is a questionnaire encompassing 13 items related to different levels of knee function, with scores ranging from zero (representing the highest possible deficit) to 100 (meaning that the subject does not present any deficit).
Knee pain
时间窗: Change from baseline in knee pain at 8 weeks.
Evaluation of pain level in the knee using the Numerical Pain Scale, graded from 0 to 10, where 0 indicates absence of pain and 10 indicates the worst pain imaginable.
次要结局
- Root Mean Square (RMS)(Change from baseline in RMS at 8 weeks.)
- Isokinetic performance(Change from baseline in total work at 8 weeks.)
- Time of muscle activation (Onset)(Change from baseline in onset of the electromyographic at 8 weeks.)
