Twenty patients with torticollis had electromyographic studies of their neck muscles performed before and after a series of local injections of botulinum toxin. The pattern of muscle activity changed after the injections, and this effect persisted even after head position had returned to baseline. Patients who did not experience any clinical benefit from the injections also demonstrated a change in the pattern of muscle activity. These results suggest that the underlying abnormality in torticollis usually involves a general motor program for head position, rather than the activity of individual neck muscles.
20名斜颈患者在接受一系列肉毒杆菌毒素局部注射前后进行了颈部肌肉的肌电图研究。注射后肌肉活动模式发生了变化，即使头部位置恢复到基线水平，这种效果仍然持续存在。那些注射后未获得任何临床益处的患者也表现出肌肉活动模式的改变。这些结果表明，斜颈的潜在异常通常涉及头部位置的一般运动程序，而不是个别颈部肌肉的活动。
