本研究的目的是测量手动颈椎牵引（MCD）过程中下颈椎椎间盘内压（IDP）的变化。在前方做切口，将压力传感器插入下颈椎间盘的每个核中。四名经验丰富的脊椎治疗医生（DC）对9例俯卧位标本进行MCD手术，在C5或C6椎体上接触，头片位于不同位置。使用描述性统计分析IDP变化、牵引力和手动施加的后向力。MCD手术期间，在所有下颈椎节段C4-C5、C5-C6和C6-C7观察到IDP降低。平均IDP下降高达168.7 KPa。平均牵引力高达119.2 N。手动牵引期间施加的后向力高达82.6 N。对于所有4个DC，IDP降低的临床医师内可靠性较高。虽然两个DC在施加牵引力方面具有较高的临床医师内可靠性，但其他两个DC仅表现出中等可靠性。在运动屈曲和牵引时，IDP降低最大。中性牵引、固定屈曲牵引和全身牵引时，患者的旋前度逐渐降低。
The objective of this study was to measure intradiscal pressure (IDP) changes in the lower cervical spine during a manual cervical distraction (MCD) procedure. Incisions were made anteriorly, and pressure transducers were inserted into each nucleus at lower cervical discs. Four skilled doctors of chiropractic (DCs) performed MCD procedure on nine specimens in prone position with contacts at C5 or at C6 vertebrae with the headpiece in different positions. IDP changes, traction forces, and manually applied posterior-to-anterior forces were analyzed using descriptive statistics. IDP decreases were observed during MCD procedure at all lower cervical levels C4-C5, C5-C6, and C6-C7. The mean IDP decreases were as high as 168.7 KPa. Mean traction forces were as high as 119.2 N. Posterior-to-anterior forces applied during manual traction were as high as 82.6 N. Intraclinician reliability for IDP decrease was high for all four DCs. While two DCs had high intraclinician reliability for applied traction force, the other two DCs demonstrated only moderate reliability. IDP decreases were greatest during moving flexion and traction. They were progressevely less pronouced with neutral traction, fixed flexion and traction, and generalized traction.
