推拿对颈椎病患者颈部肌群最大随意收缩力矩的影响

Influence of Massage on Maximal Voluntary Contraction Torque of Neck Muscles in Patients with Cervical Spondylosis

目的探讨颈椎病患者颈椎后伸和前屈肌群最大随意收缩力矩的特征和推拿对其的影响。方法设立颈椎病等长运动组(45例)、颈椎病等速运动组(52例)和正常对照组(48例),每组分青、中和老年3个亚组。所有颈椎病患者采用推拿治疗;分别在推拿治疗前、第1次和第10次推拿后,采用等速肌力测试仪测定等长和等速运动状态颈部后伸和前屈肌群最大随意收缩力矩的比值(F/E)。结果正常人等长运动F/E比值有增龄性升高的趋势(P>0.05),等速运动F/E基本一致(P>0.05);颈椎病患者等长和等速运动两组F/E值较正常人增高(P<0.05,P<0.01);推拿治疗对青中年颈椎病患者F/E值有明显改善作用(P<0.05)。结论颈椎病患者颈前屈和后伸肌群力学平衡紊乱,推拿可以改善颈椎病患者F/E值,以青中年患者最为显著。

Objective To explore the characteristics of maximal voluntary contraction torque of neck muscles in patients with cervical spondylosis and the intervention mechanism of massage. Methods The subjects were divided into three groups： isometric motion group （n=45）, isokinetic motion group （w=52） and normal group （48 healthy people）. Each group was randomly subdivided into young, middle-aged and senile groups. All patients were treated by massage. The cervical flexors and extentors peak torque （F/E） was determined before and after treatment. Results In healthy people, the F/E at isometric motion and isometric motion was similar in different age groups（P〉0.05）. While the F/E was higher in cervical spondylosis patients than in healthy people （P〈 0.05,P〈 0.01）. Massage could obviously improve F/E in young and middle-aged patients. Conclusion In cervical spondylosis patients, there is a mechanic imbalance between cervical flexors and extentors; and massage can improve F/E, especially in young and middle-aged patients.
