Adolescent idiopathic scoliosis (AIS) patients have lower physical activities when compared with healthy controls, and are associated with lower bone mineral density (BMD), muscle strength and poorer quality of life (QoL). We aimed to assess the feasibility and effects of 6-month home-based digitally supported E-Fit comprised of high-intensity interval exercises for AIS patients. 40 AIS girls aged 11-14 were randomly assigned to E-Fit or control group. E-Fit group participated in an online 6-month home-based exercise program. At baseline, 6-months and 12-months follow-up, BMD using dual-energy X-ray absorptiometry, muscle functions, physical activity using Modified Baecke Questionnaire (MBQ), and QoL using Scoliosis Research Society-22 (SRS-22r) and feedback questionnaire were investigated. 14 in E-Fit and 16 in control group completed the study. Both groups had similar baseline characteristics. At 6-months, E-Fit group showed better improvement and significant interaction effect in left femoral neck bone mineral content (p=0.021) and isometric curl up test (p=0.04). Left arm lean mass showed better improvement between 6-months and 12-months follow-up (p=0.046) and whole-body areal BMD had significant interaction effect at 12-months follow-up (p=0.077). Improvement on self-image, work and sports participation were noted in E-Fit group across time. 70% of E-Fit participants were positive towards domestic application via online platform. E-Fit showed some benefits on bone health, muscle functions, physical activity and QoL measures. Current study indicated some potential physical and psychological benefits of E-Fit for AIS girls. E-Fit was feasible to conduct online at home and might have value of promoting exercise habits among relatively inactive AIS girls.
青少年特发性脊柱侧凸（AIS）患者的身体活动水平低于健康对照组，且与较低的骨密度（BMD）、肌肉力量和较差的生活质量（QoL）有关。我们旨在评估包含高强度间歇训练的 6 个月家庭数字化支持的 E-Fit 对 AIS 患者的可行性和效果。40 名 11-14 岁的 AIS 女孩被随机分配到 E-Fit 组或对照组。E-Fit 组参加了为期 6 个月的在线家庭锻炼计划。在基线、6 个月和 12 个月随访时，使用双能 X 射线吸收法测量 BMD，使用改良 Baecke 问卷（MBQ）测量肌肉功能，使用脊柱侧凸研究协会 22 项问卷（SRS-22r）和反馈问卷测量 QoL。E-Fit 组有 14 人完成了研究，对照组有 16 人完成了研究。两组基线特征相似。在 6 个月时，E-Fit 组的左股骨颈骨矿物质含量（p=0.021）和等长卷曲测试（p=0.04）的改善更好，且具有显著的交互作用。左手臂瘦体重在 6 个月和 12 个月随访时的改善更好（p=0.046），全身面积 BMD 在 12 个月随访时具有显著的交互作用（p=0.077）。E-Fit 组在自我形象、工作和运动参与方面的改善在整个时间过程中都有所体现。70%的 E-Fit 参与者对在线平台上的家庭应用持积极态度。E-Fit 对骨骼健康、肌肉功能、身体活动和 QoL 测量有一定的益处。本研究表明，E-Fit 对 AIS 女孩具有一定的身心益处。E-Fit 在家中在线进行是可行的，可能具有促进相对不活跃的 AIS 女孩养成运动习惯的价值。
