从脊柱生物力学角度探讨应用颈椎调整手法的利与弊

Discussion on advantages and disadvantages of frequent cervical regulating manipulation from spinal biomechanics

颈椎调整手法的结构基础是外源性动力活动系统和内源性静力支持系统,在前者肌群放松时,颈椎调整手法的作用力可直达后者功能单位的力线上,并拔伸椎间盘力线,调整后关节突力线进而调整颈椎关节位置异常。而反复颈椎调整手法可经常牵拉脊柱各功能单位上的韧带、关节囊等软组织,从主观印象上看可使关节周围的软组织松弛从而使关节活动度增大,关节变松,但在客观上没有实验结果支持。笔者从脊柱生物力学角度看,颈椎调整手法的使用应根据是否有调整的指征来判断,没有指征时使用会降低脊柱自身的生物力学自我调整能力。

Cervical regulating manipulation is based on the extrinsic active system and intrinsic support system. Only when the former system is relaxed, can the motive force of regulating manipulation reach the latter system to extend the vertebral discs and regulate the posterior joints. Frequent cervical regulating manipulation can stretch soft tissue around the joint and enlarge activity of joint and make it soft from subjective views, but it isn＇t proved by experiment. From the aspect of spinal biomechanics, cervical regulating manipulation has advantages and disadvantages, so it should be used according to certain standard, or it will cut down the self-regulation activity of spinal biomechanics.
