Single fibre EMG recording from extensor digitorum communis muscle is described in patients with psychotic illness. The fibre density, or average number of single muscle fibre action potentials belonging to the same motor unit within the uptake area of the electrode, was higher in the patient group than in normal controls. Increased jitter was occasionally seen. Motor and sensory nerve conduction velocity values were within the normal range. The results indicate that psychosis is associated with denervation and reinnervation by collateral sprouting.
描述了对患有精神疾病患者的指总伸肌进行单纤维肌电图记录的情况。纤维密度，即电极摄取区域内属于同一运动单位的单根肌纤维动作电位的平均数量，在患者组中高于正常对照组。偶尔可见抖动增加。运动和感觉神经传导速度值在正常范围内。结果表明，精神病与失神经支配和侧支发芽再支配有关。
