To analyze the effects of neuromuscular electrical stimulation of the femoral quadriceps associated or not with whey protein supplementation on the electromyographic activity and body mass distribution in volunteers undergoing anterior cruciate ligament reconstruction.
24 volunteers were randomly divided into three groups: basal control, whey protein in association with neuromuscular electrical stimulation, and neuromuscular electrical stimulation alone.
In the postoperative evaluation, during the mini squat, the basal group showed a decrease in the electromyographic activity of the vastus medialis (p = 0.005, eyes open; p = 0.003, eyes closed), vastus lateralis (p = 0.005, eyes open; p = 0.020; eyes closed) and rectus femoris (p = 0.075, eyes open; p = 0.074, eyes closed) and of body mass distribution in the injured limb (p < 0.001, eyes open; p < 0.001, eyes closed), and in the healthy limb (p < 0.001, eyes open; p < 0.001, eyes closed).
The early use of neuromuscular electrical stimulation of the quadriceps femoris maintained the electromyographic activity of the vastus medialis and vastus lateralis muscles and prevented asymmetries in body mass distribution 15 days after anterior cruciate ligament reconstruction.
分析股四头肌神经肌肉电刺激联合或不联合补充乳清蛋白对前交叉韧带重建志愿者肌电图活动和体重分布的影响。
24名志愿者被随机分为三组：基础对照组、乳清蛋白联合神经肌肉电刺激组和单纯神经肌肉电刺激组。
在术后评估中，进行迷你深蹲时，基础组股内侧肌（睁眼时p = 0.005；闭眼时p = 0.003）、股外侧肌（睁眼时p = 0.005；闭眼时p = 0.020）和股直肌（睁眼时p = 0.075；闭眼时p = 0.074）的肌电图活动以及患侧肢体（睁眼时p < 0.001；闭眼时p < 0.001）和健侧肢体（睁眼时p < 0.001；闭眼时p < 0.001）的体重分布均有所下降。
股四头肌神经肌肉电刺激的早期应用可维持股内侧肌和股外侧肌的肌电图活动，并在前交叉韧带重建15天后防止体重分布不对称。
