悬吊运动疗法治疗颈椎病生物力学机制的临床研究

Clinical study on biomechanical mechanism of suspension exercise therapy( SET) for treating cervical spondylosis

目的揭示悬吊运动疗法治疗颈椎病的生物力学机制。方法 2015年8月~2016年12月,采用简单随机方法,将72例颈椎病患者随机分为实验组(SET疗法组)与对照组(牵引组),实验组36例(男9例,女27例),年龄(45.19±10.09)岁,病程(24.94±18.07)月;对照组36例(男11例,女25例),年龄(44.08±8.88)岁,病程(22.17±14.96)月。应用BiodexⅢSystem等速测试系统测试颈部肌群力学性能,治疗前和疗程结束后各测试1次。结果治疗前,两组峰力矩(peak torque,PT)、平均功率(average power,AP)、屈肌峰力矩/伸肌峰力矩比值(flexor/extensor peak torque ratio,F/E)比较没有统计学差异;治疗后,PT、AP、F/E比较,实验组优于对照组(P<0.05)。实验组治疗前后PT、AP、F/E比较有统计学差异(P<0.05)。治疗前,两组疼痛评分(VAS)比较没有统计学差异;治疗后,实验组VAS优于对照组(P<0.05);实验组治疗前后VAS比较有统计学差异(P<0.05)。结论 SET可以改善颈椎病患者颈部肌群收缩力量和做功效率,以及颈部肌群屈、伸肌群的协调能力,从而有利于恢复颈椎病患者颈部的生物力学性能。

Objective To reveal the biomechanical mechanism of suspension exercise therapy（ SET） for treating cervical spondylosis. Methods From August 2015 to December 2016,72 patients with cervical spondylosis were divided into experimental group（ SET treatment group） and control group（ traction treatment group） based on simple random sampling methods. For experimental group： 9 males and 27 females,the average age（ 45. 19 ±10. 09） years old,the average disease course（ 24. 94 ± 18. 07） months. For control group： 11 males and 25 females,the average age（ 44. 08 ± 8. 88） years old,the average disease course（ 22. 17 ± 14. 96） months. The mechanical properties of neck muscles before treatment and at the end of disease course were tested by BiodexⅢ Isokinetic Testing System. Results Before treatment,there were no signficant differences in the peak torque（ PT）,average power（ AP）,peak torque of flexor/extensor peak torque ratio（ F/E） for both groups; after treatment,PT,AP,F/E in experimental group was improved compared with those in control group（ P〈0. 05）.Significant differences in PT,AP,F/E were found for experimental group before and after SET treatment（ P〈0. 05）. There were no significant differences in visual analogue scale（ VAS） of neck pain for both groups before treatment（ P〈0. 05）,while the VAS of experimental group was better than that of control group（ P〈0. 05）. Significant differences in the VAS were found for experimental group before and after SET treatment（ P〈0. 05）. Conclusions SET can improve the contraction forces and work efficiency of neck muscles for patients with cervical spondylosis,as well as the coordination ability of flexors and extensors muscles,which will contribute to restoring biomechanical properties of the patients with cervical spodylosis.
