摘要

目的本研究的目的是确定站立时慢性腰痛患者的疼痛、残疾和腰椎多裂肌活动之间的关系。方法本横断面研究包括对150例慢性腰痛患者的随机对照试验的基线分析。分别使用视觉模拟量表、Oswestry残疾指数问卷和表面肌电图评估站立、残疾和腰椎多裂肌活动时的疼痛强度。采用多元线性回归分析腰椎多裂肌活动、站立时疼痛和残疾之间的关系。结果左侧多裂棒（LM）活动与站立时疼痛强度呈显著正相关（r = 0.328, P < .001），右侧多裂棒（LM）活动与站立时疼痛强度无显著相关。功能障碍与右侧LM活动（r = 0.180, p < 0.05）和左侧LM活动（r = 0.351, p < 0.001）呈正相关。结论腰椎多裂肌活动的增加与站立时疼痛和残疾的增加有关。

Relationship of Lumbar Multifidus Activity, Disability, and Pain During Standing in People With Chronic Low Back Pain: Cross-Sectional Study From a Randomized Controlled Trial

Objective

The purpose of this study was to determine the relationship between pain, disability, and lumbar multifidus activity in people with chronic low back pain while standing.

Methods

This cross-sectional study included baseline analysis of a randomized controlled trial of 150 patients with chronic low back pain. Pain intensity during standing, disability, and lumbar multifidus activity was assessed using a visual analog scale, the Oswestry Disability Index questionnaire, and surface electromyography, respectively. Multiple linear regression was used to analyze the association between lumbar multifidus activity, pain during standing, and disability.

Results

Lumbar multifidus (LM) activity on the right side did not significantly correlate with pain intensity during standing, except for the left-side percent maximum voluntary contraction of the LM, which showed a significant positive correlation with pain intensity (r = 0.328, P < .001). There was a positive correlation of functional disability with right-side LM activity (r = 0.180, p < .05) and left-side LM activity (r = 0.351, p < .001).
