目的 探讨单次胸椎冲击复位手法疗法对腰背肌筋膜炎患者致痛因子的影响。方法 将88例诊断为腰背肌筋膜炎的患者分为复位组、假复位组及空白对照组。在干预前、干预后15 min和干预后1 h取受试者全血及全清样本,全血样本用LPS制造炎性反应存放24 h后,通过ELISA分别测定TNF-α、IL-1β、COX-2的浓度,β-内啡肽和SP浓度则直接测定。结果 与初始水平比较,在研究期间内TNF-α、IL-1β、COX-2水平在假复位组和空白对照组中明显升高(P<0.001),P物质水平无明显变化(P>0.05),而在胸椎复位组随着研究时间推移,TNF-α、IL-1β、COX-2和P物质水平逐渐降低(P<0.05或P<0.001);组间比较,假复位组和空白对照组TNF-α、IL-1β、COX-2和P物质增高水平相比胸椎复位组有显著差异(P<0.05或P<0.001),而胸椎复位组TNF-α、IL-1β、COX-2和P物质水平在浓度LPS刺激相对假复位组和空白对照组显著性降低(P<0.001)。另外,β-内啡肽水平在假复位组和空白对照组中无显著差异 (P>0.05),而胸椎复位组随着研究时间推移则显著增高(P<0.001),组间比较有统计学差异 (P<0.001)。结论 单次胸椎冲击复位手法有助于炎性因子TNF-α、IL-1β、COX-2和神经递质P物质表达下调,并提高了β-内啡肽水平。
