Manual therapy has been recommended to reduce and prevent musculoskeletal problems related to thoracic hyperkyphosis. With recent rapid technological developments, manual techniques can now be implemented by mechanical devices; hence, mechanical massage can manipulate the back muscles and mobilize the spine.
Here, we aimed to 1) determine the effects of mechanical massage and manual therapy and 2) compare their effects on spinal posture, extension range of motion, trunk extensor electromyographic activity, and thoracic extension strength in individuals with thoracic hyperkyphosis.
Participants with thoracic hyperkyphosis were randomly assigned to the manual therapy ( = 16) or mechanical massage ( = 19) group. Each intervention was applied for 8 weeks. The participants' spinal posture, extension range of motion, trunk extensor electromyographic activity, and thoracic extension strength were measured before and after intervention.
Intergroup analyses revealed no significant differences in any variables. However, thoracic kyphosis angle, thoracic extension range of motion, longissimus thoracis electromyographic activity, iliocostalis lumborum pars lumborum activity, and thoracic extension strength differed significantly in intertime analyses. The results of paired -test analysis showed that thoracic kyphosis angle, thoracic extension range of motion, longissimus thoracis electromyographic activity, and thoracic extension strength were significantly different after intervention in both groups ( < 0.05).
Mechanical massage and manual therapy effectively improve thoracic kyphosis angle, thoracic extension range of motion, and thoracic extension strength. Therefore, mechanical massage is an alternative intervention to manual therapy for improving thoracic kyphosis angle, thoracic extension range of motion, and thoracic extension strength in participants with hyperkyphosis.

手法治疗已被推荐用于减少和预防与胸椎后凸相关的肌肉骨骼问题。随着近期技术的快速发展，现在可以通过机械设备实施手法技术；因此，机械按摩可以对背部肌肉进行操作并活动脊柱。
在此，我们旨在1）确定机械按摩和手法治疗的效果，以及2）比较它们对胸椎后凸个体的脊柱姿势、伸展活动范围、躯干伸肌肌电图活动和胸椎伸展力量的影响。
将患有胸椎后凸的参与者随机分配到手法治疗组（n = 16）或机械按摩组（n = 19）。每种干预措施应用8周。在干预前后测量参与者的脊柱姿势、伸展活动范围、躯干伸肌肌电图活动和胸椎伸展力量。
组间分析显示在任何变量上均无显著差异。然而，在组内时间分析中，胸椎后凸角度、胸椎伸展活动范围、胸最长肌肌电图活动、腰髂肋肌腰段活动和胸椎伸展力量有显著差异。配对t检验分析结果显示，两组干预后胸椎后凸角度、胸椎伸展活动范围、胸最长肌肌电图活动和胸椎伸展力量均有显著差异（P < 0.05）。
机械按摩和手法治疗均能有效改善胸椎后凸角度、胸椎伸展活动范围和胸椎伸展力量。因此，对于改善胸椎后凸个体的胸椎后凸角度、胸椎伸展活动范围和胸椎伸展力量，机械按摩是手法治疗的一种替代干预措施。本试验已在KCT0004527注册。
