To observe the effect of 12-week core stability training on Cobb angle and the ratios of AEMG (averaged EMG) and IEMG (integral EMG) of paravertebral electromyography in thoracic and lumbar segments in adolescent idiopathic scoliosis (AIS) patients and offer a practical-based evidence for the rehabilitation treatment for AIS patients.
31 AIS female middle school students were randomly divided into an exercise group ( = 16, 12 weeks of core stability training, 3 times/week) and AIS group ( = 15). In addition, 15 female secondary school students without scoliosis were included as the normal group (the AIS group and normal group did not perform any regular physical exercise throughout the trial period and only receive regular evaluation and guidance). Before and after the experiment, the digital diagnostic equipment of Philips was used to examine the Cobb angle and Noraxon was used to measure the surface EMG signals of the back thoracic and lumbar paravertebral muscles.
Compared with that before training, after 12 weeks of core stability training, the Cobb angle in the exercise group significantly decreased, and the ratio of AEMG (convex/concave) and IEMG (convex/concave) of paravertebral muscles in the thoracolumbar segment significantly decreased ( < 0.01, respectively); there was no significant difference in the above indicators in the AIS group before and after the experiment ( > 0.05, respectively). After 12 weeks of core stability training, compared with the AIS group, the Cobb angle decreased significantly ( < 0.01), and the ratio of AEMG (convex/concave) and IEMG (convex/concave) of paravertebral muscles in thoracolumbar segment decreased significantly ( < 0.01, < 0.05). Compared with the normal group, the ratio of AEMG and IEMG of paravertebral muscles in thoracolumbar segment significantly increased ( < 0.01) in the AIS group ( < 0.01, respectively).
The core stability training can significantly reduce the Cobb angle of AIS and correct the bad posture of scoliosis patients, which may be related to the balance of the electromyographic activities (convex concave side) of paravertebral muscles in AIS patients.
观察 12 周核心稳定性训练对青少年特发性脊柱侧凸（AIS）患者 Cobb 角及胸腰椎段椎旁肌表面肌电图（AEMG）和 IEMG（积分肌电图）比值的影响，为 AIS 患者康复治疗提供实践依据。
31 例 AIS 女性中学生随机分为运动组（n=16，进行 12 周核心稳定性训练，每周 3 次）和 AIS 组（n=15）。此外，纳入 15 例无脊柱侧凸的女性中学生作为正常组（AIS 组和正常组在整个试验期间均不进行任何常规体育锻炼，仅接受常规评估和指导）。使用飞利浦数字诊断设备检测 Cobb 角，使用诺澳森肌电仪测量胸腰椎段椎旁肌的表面肌电信号。
与训练前相比，运动组训练 12 周后 Cobb 角明显减小，胸腰椎段椎旁肌 AEMG（凸侧/凹侧）和 IEMG（凸侧/凹侧）比值明显减小（均 P＜0.01）；AIS 组训练前后上述指标差异均无统计学意义（均 P＞0.05）。运动组训练 12 周后 Cobb 角明显小于 AIS 组（P＜0.01），胸腰椎段椎旁肌 AEMG（凸侧/凹侧）和 IEMG（凸侧/凹侧）比值明显减小（均 P＜0.01，P＜0.05）。与正常组相比，AIS 组胸腰椎段椎旁肌 AEMG 和 IEMG 比值明显升高（均 P＜0.01）（均 P＜0.01，分别）。
核心稳定性训练能明显降低 AIS 的 Cobb 角，纠正脊柱侧凸患者的不良姿势，可能与改善 AIS 患者椎旁肌肌电活动（凸凹侧）平衡有关。
