This study aimed to explore the correlation between balance function and core muscle activation in patients with adolescent idiopathic scoliosis (AIS), compared to healthy individuals.
A total of 24 AIS patients and 25 healthy controls were recruited. The limits of stability (LOS) test were conducted to assess balance function, while surface electromyography was used to measure the activity of core muscles, including the internal oblique, external oblique, and multifidus. Diaphragm thickness was measured using ultrasound during different postural tasks. Center of pressure (COP) displacement and trunk inclination distance were also recorded during the LOS test.
AIS patients showed significantly greater activation of superficial core muscles, such as the internal and external oblique muscles, compared to the control group (p < 0.05). Diaphragm activation was lower in AIS patients during balance tasks (p < 0.01). Although no significant difference was observed in COP displacement between the groups, trunk inclination was significantly greater in the AIS group during certain tasks (p < 0.05).
These findings suggest distinct postural control patterns in AIS patients, highlighting the importance of targeted interventions to improve balance and core muscle function in this population.
本研究旨在探讨青少年特发性脊柱侧凸（AIS）患者与健康个体相比，平衡功能与核心肌肉激活之间的相关性。
共招募了24名AIS患者和25名健康对照者。进行稳定性极限（LOS）测试以评估平衡功能，同时使用表面肌电图测量核心肌肉的活动，包括腹内斜肌、腹外斜肌和多裂肌。在不同姿势任务期间使用超声测量膈肌厚度。在LOS测试期间还记录了压力中心（COP）位移和躯干倾斜距离。
与对照组相比，AIS患者的浅层核心肌肉，如腹内斜肌和腹外斜肌，激活明显更强（p < 0.05）。在平衡任务期间，AIS患者的膈肌激活较低（p < 0.01）。尽管两组之间在COP位移方面未观察到显著差异，但在某些任务期间，AIS组的躯干倾斜明显更大（p < 0.05）。
这些发现表明AIS患者存在独特的姿势控制模式，突出了针对性干预对改善该人群平衡和核心肌肉功能的重要性。
