In two subjects with paramyotonia congenita the isometric torque generated by the abductor digiti minimi and the surface EMG recorded over ADM decreased during prolonged or repetitive contractions, whether these were voluntarily or electrically induced. Isometric twitch times did not alter significantly during this muscle fatigue. Cooling greatly accelerated the fatiguing process. It is suggested that this local muscle weakness is due to a progressive decrease in excitability of the muscle cell membrane.
在两名患有先天性副肌强直的受试者中，小指展肌产生的等长扭矩以及在小指展肌上记录的表面肌电图在长时间或重复收缩期间均下降，无论这些收缩是自愿诱发还是电诱发的。在这种肌肉疲劳过程中等长抽搐时间没有明显改变。冷却极大地加速了疲劳过程。提示这种局部肌肉无力是由于肌细胞膜兴奋性的逐渐降低所致。
