摘要
目的:研制一种在仰卧位颈椎牵引下进行棘突后向前关节松动术的多功能颈椎康复治疗仪,并探索不同牵引力对关节松动的影响。方法:治疗仪设计采用机电一体化结构,由机架、颈椎关节松动装置、牵引装置、微电脑控制台和驱动器等组成。5年内无颈椎病病史的健康志愿者30例,给予治疗仪仰卧中立位持续牵引下关节松动,牵引力分别为0、3、5和7kg时,治疗仪针对C5棘突行后向前关节松动,作用力幅度为10～30N,频率为1Hz,记录实时作用力并测量机械手指在颈椎上的最大位移。结果:实时记录的最大和最小平均作用力分别为(27.52±0.58)N和(4.57±0.52)N,组内相关系数(ICC)均>0.99。不同牵引力时机械手指针对C5棘突关节松动的平均最大位移差异无统计学意义。结论:本文研制的新型多功能颈椎康复治疗仪实现了在仰卧位颈椎牵引下进行安全稳定的中央后向前关节松动,为颈椎病治疗提供了新的工具。
Objective：To develop a new device combining central posteroanterior spinal mobilization with cervical traction, and to estimate the effect of traction forces on spinal mobilization. Methods：The device was designed as me- chanical and electrical integration structure,including traction and mobilization systems. Thirty asymptomatic volun- teers lied on the device with the indentor focused on the 5th cervical spinous process. Central mobilizations（10--30 N, 1Hz） were applied with different traction forces （0,3,5,7kg）. Realtime mobilization forces and displacements were recorded during treatment. Results：Mean realtime peak and minimum forees（SEM）were（27.52-4-0.58）N and （4. ,57 J： 0.52）N respectively. Intraclass correlation coefficients（ICC） of forces were more than 0.99. The mean maxi- mum displacements of indentor had no significant difference in various traction forces. Conclusion： The new device can provide consistent and safe central posteroanterior spinal mobilization in combination with traction.
