摘要:

[目的]探讨正常人和颈椎病患者颈部肌肉最大力矩角度(APT)的特征及推拿干预机制。[方法]采用等速肌力测仪评估等速运动状态颈椎病颈部肌肉APT特性,分颈椎病组(40例)和正常对照组(39例),每组按性别、年龄相匹配分青、中和老年3个亚组。推拿治疗10次,分别在推拿治疗前、第1次推拿后即刻及第10次以后进行评估。[结果]正常人APT值比较恒定,随年龄改变不明显,90°/s角速度前屈和后伸APT多位于距离中立位偏后10°～25°,25°～40°;180°/s角速度前屈和后伸APT多分别位于距离中立位偏后15°～20°,20°～30°;颈椎病患者后伸APT值与正常人有显著差异,其值多位于中立位前后10°左右<推拿可以改善最大力矩角度,尤其是后伸APT值。[结论]正常人可以作为评估颈椎病颈部肌肉功能的有效参数;推拿可以通过改善以整体恢复颈部肌肉的力学平衡。

Abstract:

[Objective] Toexplore the characteristic of the largest momental angle of cervical muscles in health persons and patients with disease ofvertebrae cervicales and the intervention mechanism of massage. [Methods] The characteristic of the largest momental angle(APT) in the patients with disease of vertebrae cervicales was evaluated by myosthenometer at movement with constant speed. Forty patients with verte-brae cervicales in treatment group and thirty-nine health persons in control group were enrolled in this study. Each group was randomly divided intosub-group of young, middle-aged and senium. The characteristic of APT was determined before and after treatment, and after the first massage. [Results] The APT value of health person was permanent and hadn't obvious change with aging. The variation angle of 90°per second anteflexion and post-extend was 10～25 degree and 25～40 degree. The variation angle of 180° per second anteflexion and behind extend was 15～20 degree and 20～30 degree. The post-extend angle ofpatients with disease ofvertebrae cervicales had more obvious difference than that of health persons. The post-extend angle in this patients was 10 degree usually. The massage may improve post-extend of the largest momental angle, especially the APT value at post-extend. [Conclusion] The APT of health persons is an effective parameter to evaluate the characteristic of cervical muscles in patients with disease of vertebrae cervicales. Massage mayrecover the mechanics balance ofcervical muscles byimprovingthe largest momental angle.
