The author reports the results of electromyographic investigations of the muscles of the nape and temporal muscles in 132 patients with headaches of different aetiology (migraine, cervical migraine, vasomotor headache, symptomatic headaches) and in 51 controls who had never had headaches. In the healthy subjects no bioelectric activity was observed when the patients relaxed completely. On the other hand, in most patients with headaches continuous bioelectric activity was observed at rest in these muscles indicating their involuntary contraction. This phenomenon is called by the author "cephalalgic" spasm of head and neck muscles, which is rather characteristic of various headaches.
作者报告了对132例不同病因（偏头痛、颈性偏头痛、血管舒缩性头痛、症状性头痛）的头痛患者以及51例从未患过头痛的对照者的项部肌肉和颞肌进行肌电图检查的结果。在健康受试者完全放松时未观察到生物电活动。另一方面，在大多数头痛患者中，这些肌肉在静息时观察到持续的生物电活动，表明它们在不自主收缩。作者将这种现象称为头颈部肌肉的“头痛性”痉挛，这在各种头痛中相当典型。
