The relevance of side-locked unilateral pain (with no side shift) in diagnosing and differentiating primary long-lasting cephalgias such as tension headache and migraine is not clear. In the present study we have retrospectively examined the frequency of side-locked unilaterality in 1169 primary headache outpatients, whose pain duration was more than four hours. The cases were migraine (66%), tension-type headache (21%) and non-classifiable headache and atypical facial pain (not well defined headaches) (13%). The occurrence of side-locked unilateral pain was more frequent in migraine (17%) than tension headache (4%). However side-locked pain was found to be more frequent in patients with not-well-defined head pain (28%). Of the 1169 patients, 181 (15%) had side-locked unilateral pain: 70% of the 181 had migraine, 25% were not-well-defined head pain cases and 5% were tension-type headache cases. The high percentage of migraine cases in the side-locked unilateral group reflects the high proportion of migraine patients in the studied population.
侧锁性单侧疼痛（无侧移）在诊断和鉴别原发性持续性头痛（如紧张性头痛和偏头痛）中的相关性尚不清楚。在本研究中，我们回顾性检查了1169例疼痛持续时间超过4小时的原发性头痛门诊患者中侧锁性单侧性的频率。这些病例包括偏头痛（66%）、紧张型头痛（21%）以及不可分类的头痛和非典型面部疼痛（未明确界定的头痛）（13%）。侧锁性单侧疼痛在偏头痛患者中（17%）比紧张性头痛患者中（4%）更常见。然而，侧锁性疼痛在未明确界定的头痛患者中（28%）更为常见。在1169例患者中，181例（15%）有侧锁性单侧疼痛：181例中的70%患有偏头痛，25%为未明确界定的头痛病例，5%为紧张型头痛病例。侧锁性单侧组中偏头痛病例的高比例反映了研究人群中偏头痛患者的高比例。
