目的：分析腰椎间盘突出症患者首次核心稳定性训练前后即刻的表面肌电信号特征。方法收集诊断明确且符合纳入标准的腰椎间盘突出症患者30例，均在专业的治疗师指导下进行一次核心稳定性训练，应用Biering-Sorensen腰背肌等长收缩测试方法，于腰部两侧竖脊肌及多裂肌处记录核心稳定性训练前和训练后即刻的表面肌电信号，并提取平均肌电值（AEMG）、中位频率值（MF）进行统计学分析。结果训练前的痛侧竖脊肌MF值、多裂肌MF值、多裂肌AEMG值均小于非痛侧，差异均有统计学意义（t分别=3.44、6.06、4.02，P均＜0.05）；训练后的痛侧竖脊肌MF值、多裂肌MF值、多裂肌AEMG值仍小于非痛侧，差异均有统计学意义（t分别=2.24、6.27、4.12，P均＜0.05）；训练后痛侧竖脊肌与多裂肌AEMG值较训练前增大，但均差异无统计学意义（t分别=1.65、1.23，P均＞0.05）；训练后痛侧多裂肌MF值较训练前低，差异有统计学意义（t=3.91，P＜0.05）。结论核心稳定性训练可激活腰椎间盘突出症患者腰背部核心肌群，可针对性的应用于深层核心肌群多裂肌的强化训练。
目的：分析腰椎間盤突齣癥患者首次覈心穩定性訓練前後即刻的錶麵肌電信號特徵。方法收集診斷明確且符閤納入標準的腰椎間盤突齣癥患者30例，均在專業的治療師指導下進行一次覈心穩定性訓練，應用Biering-Sorensen腰揹肌等長收縮測試方法，于腰部兩側豎脊肌及多裂肌處記錄覈心穩定性訓練前和訓練後即刻的錶麵肌電信號，併提取平均肌電值（AEMG）、中位頻率值（MF）進行統計學分析。結果訓練前的痛側豎脊肌MF值、多裂肌MF值、多裂肌AEMG值均小于非痛側，差異均有統計學意義（t分彆=3.44、6.06、4.02，P均＜0.05）；訓練後的痛側豎脊肌MF值、多裂肌MF值、多裂肌AEMG值仍小于非痛側，差異均有統計學意義（t分彆=2.24、6.27、4.12，P均＜0.05）；訓練後痛側豎脊肌與多裂肌AEMG值較訓練前增大，但均差異無統計學意義（t分彆=1.65、1.23，P均＞0.05）；訓練後痛側多裂肌MF值較訓練前低，差異有統計學意義（t=3.91，P＜0.05）。結論覈心穩定性訓練可激活腰椎間盤突齣癥患者腰揹部覈心肌群，可針對性的應用于深層覈心肌群多裂肌的彊化訓練。

Objective To analyze the characteristics of surface electromyogram signal (SEMG) signals in patients with lumbar disc herniation before and after the core stability exercise. Methods Thirty cases diagnosed patients with lumbar disc herniation treated with the core stability exercise. The Biering-Sorensen back muscle extension test was taken and the SEMG from erector spinae and multifidus muscle were recorded immediately before and after exercise. The averaged elec-tromyogram(AEMG) and medium frequency(MF) value were extracted for analyses. Results Before training, the differ-ences of MF value of erector spinae and lumbar multifidus and AEMG values of lumbar multifidus between the unaffected side and the affected side were statistically significant as well as the condition that after the core stability exercise (t=3.44,6.06,4.02; 2.24,6.27,4.12,P<0.05). After the core stability exercise, AEMG value of erector spinae and multifidus in affected side were higher than before training with no significant differences(t=1.65,1.23,P>0.05) and the MF value in affected side was significantly lower than before training (t=3.91,P<0.05). Conclusion Core stability exercise can acti-vate the deep lumbar muscles. It suggested that core stability exercise was helpful in training the lumbar multifidus muscle.
