【摘要】 目的:探讨手法影响颈部体表变形参数、及推拿治疗颈椎病的生物力学机制。方法:运用生物力学传感器技术,测试受试对象在不同屈伸角度的颈部体表变形参数。结果:(1)颈部体表位移参数随头颈前屈角度增大而明显增大,相对于-10°(后伸)+10°(前屈)时位移变量均数差为0.018mm,+30°(前屈)时达到1.952mm(P<0.05),该变量随年龄增长而减小。(2)颈伸肌柔性系数随着年龄的增加呈现出减低的趋势,随前屈角度增加柔性系数增大。结论:颈部体表位移参数变化是颈椎病的一个特征性表现,推拿治疗颈椎病应对该参数进行有针对性的处理,其力学性能的改善是推拿治疗颈椎病疗效基础之一。更多还原

【Abstract】 Objective:The purpose of this study is to investigate the body-surface-displacement of cervical extension muscles and to reveal the pathological mechanism of cervical spondylopathy(CS).Methods:The CS patients were tested the body-surface-displacement parameter of cervical spine in different head-neck flexion and extension degree with biomechanical transducer technique.Results:(1)The body-surface-displacement of cervical spine increasedobviously with the increasing of flexion degree. Collated to 10° extension, the difference of mean displacement is 0.018mm during 10° flexion and 1.952mm during 30° flexion(P<0.05). And its change trend is reduced with age advanced.(2)The flexibility coefficient of cervical extension muscles is decreased as the age advanced, but increased with the flexion degree augmented.Conclusion:The body-surface-displacement of cervical spine is the characteristic representation of CS.In clinic work, healthcare providers should regulate the parameter in cureing CS.A improvement in mechanical characteristics of cervical extension muscles is one of the significant foundation for good effect in treating CS with Tuina therapy.更多还原
