Age-related changes in cervical range of motion and its relationship with cervical spondylosis in school students aged 12–18 in Nanyang City

Abstract

Objective To investigate the age-related changes in cervical range of motion (CROM) and its relationship with cervical spondylosis in school students aged 12–18 in Nanyang City, to provide reference for prevention, early diagnosis and treatment evaluation of cervical spondylosis.

Methods Stratified sampling was adopted in 13 counties and districts of Nanyang City and 890 students aged 12–18 were assessed for CROM using the Coda Motion Analyzer. SPSS 19.0 was used to data analyze.

Results A decreasing trend was observed in CROM among boys and girls aged 12–18 years in Nanyang. For boys aged 15 and 18 years old, higher anterior flexion ( t=2.02, 2.70), posterior extension ( t=2.01, 2.81), left flexion ( t=3.51, 2.99), right flexion ( t=5.07, 2.66), sinistral ( t=2.28, 2.92) and dextral ( t=2.91, 3.60) were found compared with younger age groups ( P<0.05). Similar findings were found in girls aged 15-and 18-years old [anterior flexion ( t=2.38, 2.20), posterior extension ( t=2.09, 2.02), left flexion ( t=2.33, 2.55), right flexion ( t=7.34, 4.60), sinistral ( t=3.73, 2.35) and dextral ( t=2.31, 3.99, P<0.05). Except for the right flexion, the CROM of boys in was higher than that of girls at the same age group. The prevalence of cervical spondylosis showed an increasing trend (boys: χ ² _trend=13.93, girls: χ ² _trend=12.87, P<0.05). Except for 14-year-old group, the prevalence of cervical spondylosis in girls was higher than that in boys, with significant differences observed in 15-and 17-year-old groups (χ ²=10.35, 9.64, P<0.05).

Conclusion With the increase of age, the CROM of male and female students shows a downward trend in general. The prevalence of cervical spondylosis increases with the decrease of CROM. CROM measurement is conducive to the prevention, early diagnosis and treatment of juvenile cervical spondylosis.

【摘要】 目的 了解南阳市 12~18 岁在校学生颈椎活动度(cervical range of motion, CROM) 的年龄变化特点及与颈椎病 的关系, 为青少年颈椎病的预防、早期诊断及治疗效果的评估提供参考。 方法 在南阳市采用分层随机整群抽样方法, 使 用 Coda Motion 运动分析仪检测 890 名12~18 岁学生的 CROM, 用 SPSS 19.0 对数据进行处理。 结果 南阳市 12~18 岁男 女生 CROM 总体呈下降趋势。15 和 18 岁组男生颈椎前屈、后伸、左侧屈、右侧屈、左旋和右旋活动度与前一年龄组相比差 异均有统计学意义 ( t _前屈 值分别为 2.02, 2.70; t _后伸 值分别 2.01, 2.81; t _左侧屈 值分别为 3.51, 2.99; t _右侧屈 值分别为 5.07, 2.66; t _左旋 值分别为 2.28, 2.92; t _右旋 值分别为 2.91, 3.60, P 值均<0.05); 15 和 18 岁组女生与前一年龄组相比差异均有统计学意义 ( t _前屈值分别为 2.38, 2.20; t _后伸值分别 2.09, 2.02; t _左侧屈值分别为 2.33, 2.55; t _右侧屈值分别为 7.34, 4.60; t _左旋值分别为 3.73, 2.35; t _右旋值分别为 2.31, 3.99, P 均<0.05); 除右侧屈外, 同年龄组男生 CROM 均大于女生。颈椎病检出率总体呈增髙趋 势(男生: χ ² _趋势=13.93, 女生: χ ² _趋势=12.87, P 值均<0.05)。除 14 岁外, 其他年龄段女生颈椎病检出率均髙于男性, 15 和 17 岁 年龄组性别差异具有统计学意义 (χ ² 值分别为 10.35, 9.64, P 值均<0.05)。 结论 随年龄增长, 男女生的 CROM 整体呈下 降趋势, 且 CROM 越小, 颈椎病发生率越髙。CROM 的测量有利于青少年颈椎病的预防、早期诊断及治疗效果。
