In 2 patients with retrocollis, the positive effects obtained by stereotactic high frequency coagulation of the prestitial nucleus on the tonic activity of the neck muscle were studied electromyographically and clinically. Before the stereotactic therapy, electromyographic recordings at rest were recorded from the musculi splenii. During stimulation of the prestitial nucleus at frequencies of 8, 25 and 50 Hz, the EMG activity at rest diminished in frequency and amplitude and ultimately disappeared. Passage from the EMG recordings at rest to electrical silence took place, in one case, though a rhythmic activity of potentials grouped at 11/s. After coagulation of the prestitial nucleus, the involuntary contractions of neck muscles disappeared and electrical silence occurred. On reexamination 1 month later, the positive results were still present.
对2例患有颈部后屈的患者，通过立体定向高频凝固间质核来研究其对颈部肌肉强直活动的积极作用，并进行了肌电图和临床研究。在立体定向治疗前，从斜方肌记录静息时的肌电图。在以8、25和50Hz的频率刺激间质核时，静息时的肌电图活动在频率和幅度上均减弱，最终消失。在1例患者中，静息时的肌电图记录先出现频率为11次/秒的电位节律性活动，然后才过渡到电静息状态。在凝固间质核后，颈部肌肉的不自主收缩消失，出现电静息状态。1个月后复查，阳性结果仍然存在。
