Motor end plate jitter was studied by single fibre EMG in the orbicularis oculi muscle of eight patients with facioscapulohumeral dystrophy activated by extramuscular nerve stimulation. The jitter was found to be slightly larger in comparison with the normal controls, although still within the normal limits in each patient. The findings are considered to indicate absence of any significant neuromuscular transmission disturbance, inflammatory or regenerative process, or reinnervation in progress. There was no evidence of muscle fibre conduction abnormality even in very weak muscle.
通过对8例面肩肱型肌营养不良患者眼轮匝肌进行肌外神经刺激激活后，采用单纤维肌电图研究运动终板颤抖。与正常对照组相比，发现颤抖略大，尽管每位患者仍在正常范围内。这些发现被认为表明不存在任何明显的神经肌肉传递障碍、炎症或再生过程，或正在进行的再支配。即使在非常弱的肌肉中，也没有肌肉纤维传导异常的证据。
