Spinal Manipulative Therapy (SMT) benefits LBP patients, but its mechanism is not well documented. One hypothesis indicates that SMT restores interspinal movements. Ultrasound measurement (UM) of spinous process separation (SPS) assesses the intersegmental movements.
We used the test-retest reliability of UM between the L3, L4, L5, and S1 spinous processes on fifteen asymptomatic volunteers while lying prone on a chiropractic table. The participants then walked around for over 5 minutes, and ultrasound images were reperformed prone. UM identified the tips of the spinous processes and distances between L3-L4, L4-L5, and L5-S1. Reliability was assessed using intra-class correlation coefficient (ICC).
ICC values of SPS measurements were 0.982 for L3-L4, 0.992 for L4-L5, and 0.997 for L5-S1. Rootmean square difference between the two measures were 0.35mm for L5-S1, 0.36mm for L4-L5, and 0.57mm for L3-L4.
This study found UM to be reliable in measuring interspinous distance.
脊柱推拿疗法(SMT)对腰痛患者有益,但其机制尚无充分文献记载。一种假说认为,SMT可恢复椎间运动。棘突间距(SPS)的超声测量(UM)可评估节段间运动。
我们对15名无症状志愿者趴在整脊床上时L3、L4、L5和S1棘突之间的UM进行了重测信度研究。参与者随后走动5分钟以上,然后再次趴在床上进行超声成像。UM确定了棘突尖端以及L3-L4、L4-L5和L5-S1之间的距离。使用组内相关系数(ICC)评估信度。
L3-L4的SPS测量ICC值为0.982,L4-L5为0.992,L5-S1为0.997。两次测量之间的均方根差异L5-S1为0.35mm,L4-L5为0.36mm,L3-L4为0.57mm。
本研究发现UM在测量棘突间距离方面具有可靠性。
