目的：前十字韧带重建后，限制负重和制动会导致大腿和小腿肌肉萎缩和无力。目的：探讨电刺激对前交叉韧带重建术后早期康复患者肌萎缩的预防作用。方法：将20例急性前交叉韧带损伤患者随机分为两组。对照组(CON组)只进行常规康复训练。在此基础上，电肌肉刺激组(EMS组)在术后第2天至术后4周接受20 Hz指数脉冲波形的EMS训练。结果：EMS组术后4周股外侧肌和小腿肌层厚度显著增加，而CON组显著减少。术后4周EMS组伸膝力量下降幅度明显小于CON组，术后3个月EMS组伸膝力量恢复较快。结论：早期康复阶段实施EMS能有效地维持和增加术后肢体肌肉厚度和肌力。(C)2011爱思唯尔有限公司。保留所有权利。
Objective:Following anterior cruciate ligament (ACL) reconstruction, restricted weight bearing and immobilization results in thigh and calf muscle atrophy and weakness. The purpose of this study was to assess the effect of electrical muscle stimulation (EMS) on prevention of muscle atrophy in patients during the early rehabilitation stage after ACL reconstruction.Methods:Twenty patients with acute ACL tears were divided into two groups randomly. The control group (CON group) participated in only the usual rehabilitation program. In addition to this protocol, the electrical muscle stimulation group (EMS group) received EMS training using the wave form of 20 Hz exponential pulse from the 2nd post-operative day to 4 weeks after the surgery.Results:Muscle thickness of vastus lateralis and calf increased significantly 4 weeks after surgery in the EMS group, while it decreased significantly in the CON group. The decline of knee extension strength was significantly less in the EMS group than in the CON group at 4 weeks after the surgery, and the EMS group showed greater recovery of knee extension strength at 3 months after surgery.Conclusions:EMS implemented during the early rehabilitation stage is effective in maintaining and increasing muscle thickness and strength in the operated limb.
