目的 通过影像学及电生理方法探讨单侧症状腰椎间盘突出患者双侧多裂肌的病理生理变化.方法 选取出现单侧症状的腰椎间盘突出患者36例,按患侧(主诉疼痛侧)与对侧不同,将数据分为患侧组和对侧组.采用磁共振成像(MRI)测量患者双侧多裂肌的脂肪化面积及总平均信号强度值,利用肌电图(EMG)检查患者双侧多裂肌等长收缩时的波幅和运动单位时限值.测量完成后,对数据进行分析处理.结果 36例患者的双侧多裂肌均有不同程度的脂肪化,且患侧组多裂肌脂肪化横断面面积(CSA)百分比[(44.20±15.14)％]较对侧组[(37.31±13.85)％]高(p＜0.05),患侧组的平均信号强度(59.03±12.73)高于对侧组(54.67±12.20) (P ＜0.05);患者双侧多裂肌EMG的波幅及运动单位时限均增高、增宽,且患侧组波幅[(861.67±171.32)μV]及运动单位时限[(14.49±2.37) ms]的变化较对侧组显著(P＜0.05).结论 单侧症状腰椎间盘突出患者双侧多裂肌的影像学及电生理指标均会发生改变,且患侧较为明显.
目的 通過影像學及電生理方法探討單側癥狀腰椎間盤突齣患者雙側多裂肌的病理生理變化.方法 選取齣現單側癥狀的腰椎間盤突齣患者36例,按患側(主訴疼痛側)與對側不同,將數據分為患側組和對側組.採用磁共振成像(MRI)測量患者雙側多裂肌的脂肪化麵積及總平均信號彊度值,利用肌電圖(EMG)檢查患者雙側多裂肌等長收縮時的波幅和運動單位時限值.測量完成後,對數據進行分析處理.結果 36例患者的雙側多裂肌均有不同程度的脂肪化,且患側組多裂肌脂肪化橫斷麵麵積(CSA)百分比[(44.20±15.14)％]較對側組[(37.31±13.85)％]高(p＜0.05),患側組的平均信號彊度(59.03±12.73)高于對側組(54.67±12.20) (P ＜0.05);患者雙側多裂肌EMG的波幅及運動單位時限均增高、增寬,且患側組波幅[(861.67±171.32)μV]及運動單位時限[(14.49±2.37) ms]的變化較對側組顯著(P＜0.05).結論 單側癥狀腰椎間盤突齣患者雙側多裂肌的影像學及電生理指標均會髮生改變,且患側較為明顯.

Objective To investigate pathophysiological changes in the multifidus muscles of patients with lumbar disc herniation.Methods Thirty-six patients with unilateral symptoms caused by lumbar disc herniation were enrolled.They were divided into a symptomatic side group and a contralateral side group according to whether their symptomatic (algetic) or contralateral side would be studied.The percentage area of pimelosis and the mean gross signal intensity of each multifidus were measured with magnetic resonance imaging (MRI)_ The amplitude and duration of motor unit potentials of each multifidus were recorded using electromyography (EMG) when the patients were performing isometric contraction.Results The bilateral multifidus muscles of 36 patients displayed various degrees of pimelosis on magnetic resonance images.The percentage of pimelosis cross-sectional area in the symptomatic side group was significantly higher than in the contralateral side group.[(44.20 ± 15.14)％ versus(37.31 ± 13.85)％,P ＜ 0.05] The mean value of the gross signal intensity was also significantly higher.Both the amplitudes and duration of the motor unit potentials recroded from the multifidus had increased and widened,but significantly more in the symptomatic side group than in the contralateral side group.Conclusions Both the imaging and electrophysiological data showed more significant changes on the symptomatic side in patients with unilateral symptoms caused by lumbar disc herniation.
