The aims of this study were to assess lumbar multifidus fatigue (LM) and transversus abdominis activation (TrA) in individuals with lumbar disc herniation associated with low back pain.
Sixty individuals were divided into the lumbar herniation (LHG, n = 30) and control groups (CG, n = 30). Fatigue of the LM was assessed using surface electromyography during the Sorensen effort test, and activation of the TrA with a pressure biofeedback unit. Pain intensity was determined using a visual analog scale and the McGill pain questionnaire. The Oswestry disability questionnaire and the Borg scale for self-evaluating exertion were used to assess functional disability.
Fatigue was significantly more intense and the TrA activation was insufficient (p < 0.01) in individuals with disc herniation relative to the control group. The LHG had mild functional disability and moderate pain. There were differences in the initial exertion self-evaluation between groups, which were not observed in the final exertion evaluation.
Individuals with lumbar disc herniation associated with low back pain have increased fatigue of the LM and decreased activation of the TrA, when compared to the control group.
本研究旨在评估伴有下腰痛的腰椎间盘突出症患者的腰多裂肌疲劳（LM）和腹横肌激活（TrA）情况。
60名个体被分为腰椎间盘突出症组（LHG，n = 30）和对照组（CG，n = 30）。在索伦森用力试验期间，使用表面肌电图评估腰多裂肌的疲劳情况，并使用压力生物反馈装置评估腹横肌的激活情况。使用视觉模拟量表和麦吉尔疼痛问卷确定疼痛强度。使用奥斯威斯利功能障碍问卷和博格自我评估运动量表评估功能障碍。
与对照组相比，椎间盘突出症患者的疲劳明显更严重，腹横肌激活不足（p < 0.01）。腰椎间盘突出症组有轻度功能障碍和中度疼痛。两组之间在初始运动自我评估方面存在差异，但在最终运动评估中未观察到。
与对照组相比，伴有下腰痛的腰椎间盘突出症患者腰多裂肌疲劳增加，腹横肌激活减少。
