A 60-year-old man with wasting and weakness of the right hand following ulnar nerve entrapment at the elbow was referred for electrotherapy. An ulnar nerve transposition had been performed 2 years previously. This had produced some improvement in nerve conduction without significantly improving hand muscle function. The right first dorsal interosseous muscle (FDI) was stimulated for 4 hours per day over a 6-week period with a stimulus pattern replicating the discharge of a single motor unit from a healthy, fatigued FDI (patterned neuromuscular stimulation or PNMS). The response was assessed using a single case design. Significant improvements in the strength and fatigue resistance of the FDI were observed, associated with improvements in general hand function. PNMS may be useful in restoring hand function in patients with muscle atrophy following entrapment neuropathy.
一名60岁男性，因肘部尺神经卡压后右手出现萎缩和无力而接受电疗转诊。两年前已进行了尺神经移位术。这使神经传导有了一些改善，但手部肌肉功能并未显著改善。在6周的时间里，每天对右侧第一背侧骨间肌（FDI）进行4小时的刺激，刺激模式模拟健康、疲劳的FDI单个运动单位的放电（模式化神经肌肉刺激或PNMS）。使用单病例设计评估反应。观察到FDI的力量和抗疲劳能力有显著改善，同时手部总体功能也有所改善。PNMS可能有助于恢复嵌压性神经病后肌肉萎缩患者的手部功能。
