Asymmetry in paraspinal muscle activities is observed in adolescent idiopathic scoliosis and may be of value for predicting curve progression. We have reported the effects of the surface electromyography biofeedback posture training program in improving the symmetry of paraspinal muscle activities and reducing the curve progression of early adolescents with mild scoliosis. This study further explored their subjective experience of the training program on posture correction and health-related quality of life.
Using purposive sampling, 13 early adolescents aged between 11 and 13 years with mild scoliosis participated in semi-structured in-depth interviews after completing 30 sessions of training. The data were recorded, transcribed, and coded using thematic analysis with NVivo 10. Significant statements and phrases were categorized into themes and subthemes.
As assessed by X-ray, five early adolescents showed at least a 5° Cobb angle reduction in spinal curvature, while eight showed no significant curve progression (a Cobb angle change under 5°). Several subthemes related to the benefits of the training program on the health-related quality of life were generated, namely (a) posture correction, (b) improvement in body appearance, (c) restoration of muscle relaxation, (d) reduction in bodily pain and fatigue, (e) enhancement of self-confidence/self-image, and (f) improvement in social functioning.
Given its positive effects, the sEMG biofeedback posture training program has the potential to be an alternative early intervention for early adolescents with mild scoliosis. Further empirical studies need to be carried out to substantiate its effectiveness and evaluate the sustainability of its benefits over time.
在青少年特发性脊柱侧弯中观察到椎旁肌活动不对称，这可能对预测侧弯进展有价值。我们已经报道了表面肌电图生物反馈姿势训练计划在改善椎旁肌活动对称性和减少轻度脊柱侧弯青少年早期侧弯进展方面的效果。本研究进一步探讨了他们对该训练计划在姿势矫正和健康相关生活质量方面的主观体验。
采用目的抽样法，13名年龄在11至13岁之间的轻度脊柱侧弯青少年在完成30次训练后参加了半结构化深度访谈。使用NVivo 10软件通过主题分析对数据进行记录、转录和编码。重要的陈述和短语被归类为主题和子主题。
经X射线评估，5名青少年早期脊柱侧弯患者脊柱曲率至少降低了5°Cobb角，而8名患者侧弯进展不明显（Cobb角变化小于5°）。产生了几个与训练计划对健康相关生活质量的益处相关的子主题，即（a）姿势矫正，（b）身体外观改善，（c）肌肉放松恢复，（d）身体疼痛和疲劳减轻，（e）自信心/自我形象增强，以及（f）社交功能改善。
鉴于其积极效果，表面肌电图生物反馈姿势训练计划有可能成为轻度脊柱侧弯青少年早期的一种替代早期干预措施。需要开展进一步的实证研究来证实其有效性，并评估其益处随时间的可持续性。
