[Purpose] Postural assessment and correction is a common approach in patient management to decrease symptoms and improve function for patients. The purpose of this study was to determine the effects of high-power posing on muscle strength and pain threshold. [Subjects and Methods] Thirty-one subjects, 16 females and 15 males, mean age 28.9 (SD 10.8) years old, were recruited through a convenience sampling on the university campus. The research design was a randomized controlled trial. In the experimental group, the subjects were instructed to stand in a high-power posture. In the control group, the subjects were instructed to stand in a low-power posture. Grip strength and pain threshold measurements were conducted before and after the postural intervention. [Results] The grip strength changed by -3.4 (-3.7, 0.3) % and 1.7 (-3.6, 5.3) % for the experimental and control groups, respectively. The pain threshold changed by 0.6 (-9.9, 10.4) % and 15.1 (-9.3, 24.4) % for the experimental and control groups, respectively. However, both changes were not significant as all the 95% CIs included 0. [Conclusions] The data did not show significant benefits of high-power posing in increasing grip strength and pain threshold compared to low-power posing.
[目的] 姿势评估与矫正作为患者管理中的常用方法，旨在减轻患者症状并改善其功能。本研究旨在确定高能量姿势对肌肉力量和疼痛阈值的影响。[对象与方法] 通过在大学校园进行便利抽样，招募了31名受试者，其中女性16名，男性15名，平均年龄28.9（标准差10.8）岁。研究设计为随机对照试验。在实验组中，受试者被指导以高能量姿势站立。在对照组中，受试者被指导以低能量姿势站立。在姿势干预前后进行握力和疼痛阈值测量。[结果] 实验组和对照组的握力变化分别为-3.4（-3.7，0.3）%和1.7（-3.6，5.3）%。实验组和对照组的疼痛阈值变化分别为0.6（-9.9，10.4）%和15.1（-9.3，24.4）%。然而，由于所有95%置信区间均包含0，这两个变化均无统计学意义。[结论] 与低能量姿势相比，数据未显示高能量姿势在增加握力和疼痛阈值方面具有显著益处。
