Physical activities such as walking and climbing stairs are pervasive in human daily life. Individuals with scoliosis frequently encounter dysfunction in their muscle recruitment. Multiple studies have corroborated the presence of muscle dysfunction in individuals diagnosed with scoliosis. However, there is currently a noteworthy research gap regarding the exploration of changes in muscle characteristics and disparities from those observed in individuals without scoliosis during everyday activities, specifically stair climbing.
This study aims to examine the unique patterns of muscle activity during daily life in individuals with scoliosis and distinguish the specific differences between scoliosis patients and the healthy controls. The findings of this study are significantly important for the future accurate assessment of scoliosis and the development of rehabilitation treatment plans.
Case-control study.
Twenty eight idiopathic scoliosis patients and twenty eight controls.
Root Mean Square(RMS), Maximum Voluntary Isometric Contraction(MVIC)%, RMS ratio(RMS convex / RMS concave).
The surface electromyography (sEMG) device used in this study was the Delsys Trigno, with a sampling frequency of 1500 Hz. It recorded the activation level, peak contraction, and average activation level of the erector spinae (at T6, T10, and L3 levels), gluteus maximus, gluteus medius, external oblique, and rectus abdominis muscles during three different types of locomotion for both the 28 individuals with idiopathic scoliosis and the 28 control participants.
The movement patterns of the idiopathic scoliosis patients significantly differ from those of the normal population during level walking and ascending or descending stairs. In level walking, there is an asymmetry in the activation levels of the T6 and L3 erector spinae muscles, with lower activation on the convex side compared to the concave side. Similarly, during stair ascent, the activation of the T6 and T10 erector spinae muscles is asymmetric, with higher activation on the convex side than the concave side. Moreover, during stair descent, the activation of the T6 erector spinae muscle is asymmetric, with higher activation on the convex side than the concave side.
During level walking and stair activities, idiopathic scoliosis patients exhibit pronounced abnormal movement patterns that significantly differ from those of the control group. Under different activity conditions such as level walking, ascending and descending stairs, idiopathic scoliosis patients demonstrate abnormal muscle activation in different segments of the spine. It is crucial for clinicians to prioritize the symmetry of muscle activation in the spinal region of idiopathic scoliosis patients and consider incorporating symmetry training for these muscles.
行走和爬楼梯等身体活动在人类日常生活中普遍存在。患有脊柱侧凸的个体经常会出现肌肉募集功能障碍。多项研究证实，脊柱侧凸患者存在肌肉功能障碍。然而，目前有一个值得注意的研究空白，即探索在日常活动（特别是爬楼梯）中，脊柱侧凸患者与无脊柱侧凸个体之间肌肉特征的变化和差异。
本研究旨在研究脊柱侧凸患者日常生活中的肌肉活动的独特模式，并区分脊柱侧凸患者与健康对照组之间的具体差异。本研究的结果对未来准确评估脊柱侧凸和制定康复治疗计划具有重要意义。
病例对照研究。
28 例特发性脊柱侧凸患者和 28 例对照。
均方根值（RMS）、最大随意等长收缩百分比（MVIC%）、均方根比（凸侧 RMS/凹侧 RMS）。
本研究使用的表面肌电图（sEMG）设备是 Delsys Trigno，采样频率为 1500 Hz。它记录了 28 例特发性脊柱侧凸患者和 28 例对照参与者在三种不同类型的运动（平地行走、上下楼梯）中 T6、T10 和 L3 水平的竖脊肌、臀大肌、臀中肌、腹外斜肌和腹直肌的激活水平、峰值收缩和平均激活水平。
特发性脊柱侧凸患者的运动模式在平地行走和上下楼梯时与正常人群明显不同。在平地行走时，T6 和 L3 竖脊肌的激活水平存在不对称，凸侧的激活水平低于凹侧。同样，在上楼梯时，T6 和 T10 竖脊肌的激活也是不对称的，凸侧的激活水平高于凹侧。此外，在下楼梯时，T6 竖脊肌的激活也是不对称的，凸侧的激活水平高于凹侧。
在平地行走和楼梯活动中，特发性脊柱侧凸患者表现出明显的异常运动模式，与对照组明显不同。在平地行走、上下楼梯等不同活动条件下，特发性脊柱侧凸患者的脊柱不同节段存在肌肉激活异常。对于临床医生来说，优先考虑特发性脊柱侧凸患者脊柱区域肌肉激活的对称性，并考虑对这些肌肉进行对称性训练至关重要。
