Two new chronic paroxysmal hemicrania patients are described. In both, attacks can be precipitated mechanically by applying firm manual pressure to certain sensitive points on the neck, i.e. in the C2 area, in the transverse processes of the C4-C5 vertebrae, or beneath the posterior part of the skull on the symptomatic side. The most sensitive area seems to be the transverse process of C4-C5. Susceptibility to this type of attack is dependent on the flow of spontaneous attacks; attacks are easily precipitated in a phase with multiple spontaneous attacks, but are not readily precipitated otherwise. Under indomethacin protection, local tenderness is clearly diminished and attacks cannot be precipitated.
本文描述了两名新的慢性阵发性偏侧头痛患者。在这两名患者中，通过对颈部某些敏感点施加有力的手动压力，即C2区域、C4 - C5椎体横突或症状侧颅骨后部下方，可以机械性地诱发发作。最敏感的区域似乎是C4 - C5横突。对这种类型发作的易感性取决于自发发作的频率；在有多次自发发作的阶段很容易诱发发作，否则不容易诱发。在吲哚美辛的保护下，局部压痛明显减轻，且无法诱发发作。
