Poor posture, particularly forward head posture and rounded shoulders, has become increasingly prevalent among adolescents due to prolonged screen use and sedentary behaviors. This study aimed to investigate the effects of a 6-week digital health corrective posture exercise (DHCPE) program on head and shoulder posture in adolescents.
A total of 36 subjects were recruited and randomly allocated to 3 groups: the DHCPE group, the face-to-face exercise (FTFE) group, and a control group. The DHCPE and FTFE groups participated in the same corrective posture exercise programs. The DHCPE group conducted the digital health intervention remotely through a monitored screen, while the FTFE group engaged in corrective posture exercises on-site with therapists. Each intervention lasted 50 minutes and was conducted 3 times a week over a period of 6 weeks for both groups. The outcome measurements included protracted head and shoulder distances, trunk lean (the angle of shoulder inclination relative to the pelvis), trunk deviation, shoulder and pelvic height levels, and the absolute differences and inequality ratios between both sides. All assessments were conducted both preintervention and postintervention.
Both the DHCPE and FTFE groups demonstrated significant improvements in protracted head, left protracted shoulder, and trunk lean following the intervention. The interaction effect revealed that both the DHCPE and FTFE groups exhibited significant improvements in these measurements compared with the control group. Furthermore, no significant differences were found between the improvements observed in the DHCPE group and those in the FTFE group.
DHCPE and FTFE were effective in improving head and shoulder posture in adolescents. The improvements in the DHCPE group were comparable to those achieved in the FTFE group. DHCPE has the potential to serve as a viable alternative to FTFE for enhancing head and shoulder posture in this population.
由于长时间使用电子设备和久坐行为，不良姿势，尤其是头部前倾和圆肩，在青少年中越来越普遍。本研究旨在调查为期6周的数字健康矫正姿势锻炼（DHCPE）计划对青少年头部和肩部姿势的影响。
共招募36名受试者，随机分为3组：DHCPE组、面对面锻炼（FTFE）组和对照组。DHCPE组和FTFE组参加相同的矫正姿势锻炼计划。DHCPE组通过受监控的屏幕远程进行数字健康干预，而FTFE组与治疗师在现场进行矫正姿势锻炼。每组干预持续50分钟，每周进行3次，为期6周。结果测量包括头部和肩部前伸距离、躯干倾斜度（肩部相对于骨盆的倾斜角度）、躯干偏差、肩部和骨盆高度水平，以及两侧的绝对差异和不平等比率。所有评估均在干预前和干预后进行。
干预后，DHCPE组和FTFE组在头部前伸、左侧肩部前伸和躯干倾斜方面均有显著改善。交互作用表明，与对照组相比，DHCPE组和FTFE组在这些测量指标上均有显著改善。此外，DHCPE组和FTFE组观察到的改善之间没有显著差异。
DHCPE和FTFE在改善青少年头部和肩部姿势方面有效。DHCPE组的改善与FTFE组相当。DHCPE有可能成为FTFE的可行替代方案，用于改善该人群的头部和肩部姿势。
