Nine children suffering from progressive muscular dystrophy (7 Duchenne and 2 Becker) were included in a program of low-frequency electrical stimulation (LFES) of the right tibialis anterior (TA) muscle. Muscle strength and muscle fatigue were estimated by measuring torques in the ankle during attempts of maximal voluntary contraction (MVC) in the direction of dorsal flexion of the foot and during electrically evoked contractions (EEC). No important increase in the strength of the stimulated muscles was noticed in 4 boys whose muscles were stimulated for 3 months. The muscles of 5 boys who were subjected to electrical stimulation for 9 months showed an improvement; 6 measurements made during the stimulation program revealed that changes of torques in the ankle of the right stimulated extremity were significantly different (P less than 0.001) from the changes of torques in the ankle of the left nonstimulated extremity.
9名患有进行性肌营养不良症的儿童（7名杜兴氏型和2名贝克氏型）被纳入一项对右侧胫前肌进行低频电刺激（LFES）的项目。通过在足背屈方向进行最大自主收缩（MVC）尝试期间以及电诱发收缩（EEC）期间测量踝关节扭矩来评估肌肉力量和肌肉疲劳。4名接受3个月肌肉刺激的男孩未发现受刺激肌肉力量有显著增加。5名接受9个月电刺激的男孩的肌肉显示出改善；在刺激项目期间进行的6次测量表明，右侧受刺激肢体踝关节扭矩的变化与左侧未受刺激肢体踝关节扭矩的变化有显著差异（P小于0.001）。
