Eight patients undergoing reconstruction of the anterior cruciate ligament were randomly allocated into two groups. The control group received a standard plaster cast and isometric muscle training. The stimulated group received a standard plaster cast, isometric training, and percutaneous electrical stimulation during the recovery period. The patients were examined clinically and with repeated muscle biopsies before surgery, 1 week after surgery, and 5 weeks after surgery at the time of removal of the cast. The electrically stimulated group had better muscle function from a clinical point of view and their succinate dehydrogenase activities were significantly higher than those in the control group. Electrical stimulation thus could prevent the fall in oxidative enzyme activity which was noted in the control group. The results suggest that percutaneous electrical stimulation may be a way of preventing muscle atrophy after major knee ligament surgery in athletes.
八名接受前交叉韧带重建手术的患者被随机分为两组。对照组接受标准石膏固定和等长肌肉训练。刺激组在恢复期接受标准石膏固定、等长训练和经皮电刺激。在手术前、手术后1周以及拆除石膏时的手术后5周，对患者进行临床检查并重复进行肌肉活检。从临床角度来看，电刺激组的肌肉功能更好，其琥珀酸脱氢酶活性显著高于对照组。因此，电刺激可以防止对照组中出现的氧化酶活性下降。结果表明，经皮电刺激可能是预防运动员膝关节主要韧带手术后肌肉萎缩的一种方法。
