Cervical-flexibility examination is routinely performed in neck-pain patients. However, diagnosis of cervical-flexibility impairment requires physiological reference values, which vary widely among the population. Although there is a general understanding that the cervical range of motion (RoM) alters with age and sex, the consolidated details of these variations remain lacking. A systematic review and meta-analysis was performed to evaluate the difference of cervical RoM in different age and sex populations. The quality-assessment tool for quantitative studies was applied to assess methodological quality. We identified 4,034 abstracts through a database search and 3 publications through a manual search. Thirty-four cross-sectional studies were selected for the systematic review and measuring technologies were identified. The difference in age descriptions was substantial and a strong discrepancy existed between the mobility measured by radiological and non-radiological devices. Therefore, only 11 non-radiological studies with similar age descriptions were selected for meta-analysis. Cervical RoMs varied considerably among the populations and generally decreased with age. However, this diminishment started earlier and ended later in males, and was not continuous across age in both sexes. Females normally displayed a greater RoM than males, except in lateral bending. In young subjects, the difference between males and females was not significant. For subjects in their 50s, males displayed a non-significantly greater RoM than females. The variability of cervical RoMs can be explained by different devices as well as age and sex. However, the age-dependent reduction is not continuous and differs between males and females. These findings lay the foundation for a better understanding of the incidence of age- and sex-dependent cervical disorders, and may have important implications for the long-term success of different clinical interventions.
颈椎灵活性检查在颈部疼痛患者中常规进行。然而，颈椎灵活性受损的诊断需要生理参考值，而这些值在人群中差异很大。尽管人们普遍认为颈椎活动范围（RoM）会随年龄和性别而变化，但这些变化的详细综合情况仍然缺乏。本研究进行了一项系统评价和荟萃分析，以评估不同年龄和性别人群颈椎RoM的差异。采用定量研究的质量评估工具来评估方法学质量。通过数据库检索我们识别出4034篇摘要，通过手工检索识别出3篇出版物。选择了34项横断面研究进行系统评价，并确定了测量技术。年龄描述的差异很大，放射学和非放射学设备测量的活动度之间存在很大差异。因此，仅选择了11项年龄描述相似的非放射学研究进行荟萃分析。颈椎RoM在不同人群中差异很大，并且一般随年龄增长而降低。然而，这种降低在男性中开始得更早、结束得更晚，并且在两性中随年龄变化并非连续。女性通常比男性表现出更大的RoM，但侧弯情况除外。在年轻受试者中，男性和女性之间的差异不显著。对于50多岁的受试者，男性的RoM略高于女性，但差异不显著。颈椎RoM的变异性可以通过不同的设备以及年龄和性别来解释。然而，年龄依赖性降低并非连续，且男女之间存在差异。这些发现为更好地理解年龄和性别依赖性颈椎疾病的发病率奠定了基础，并且可能对不同临床干预措施的长期成功具有重要意义。
