Immobilization of an extremity inevitably results in disuse muscle atrophy. The effectiveness of transcutaneous muscle stimulation by a portable device in preventing atrophy has been determined. Ten patients treated by open meniscectomy and given the usual isometric training were matched with ten patients in whom electrostimulation, consisting of a strong, tetanizing, five-second sustained muscular contraction about 400 times/day, was used for two weeks. Muscular strength and leg circumference were measured before surgery and four weeks after surgery. The electrically stimulated group had a significantly smaller loss of muscle volume and muscle strength, were able to walk earlier without crutches, had a greater range of knee motion, had much less postoperative knee swelling, and used significantly less pain medication. Transcutaneous electrical stimulation may prevent muscle atrophy due to immobilization, thereby shortening rehabilitation time.
肢体固定不可避免地会导致废用性肌肉萎缩。已确定一种便携式设备经皮肌肉刺激在预防萎缩方面的有效性。10例接受开放性半月板切除术并进行常规等长训练的患者与10例采用电刺激的患者进行匹配，电刺激包括每天约400次、每次持续5秒的强烈强直肌肉收缩，持续两周。在手术前和手术后四周测量肌肉力量和腿围。电刺激组的肌肉体积和肌肉力量损失明显较小，能够更早地不用拐杖行走，膝关节活动范围更大，术后膝关节肿胀明显减轻，且使用的止痛药物明显更少。经皮电刺激可能预防因固定导致的肌肉萎缩，从而缩短康复时间。
