Evidence is growing that computer users are at increased risk of developing musculoskeletal disorders, particularly those involving the upper extremity, with significant financial cost and lost productivity.
The purpose of this study was to determine the short-term effects of wearing a dynamic elastic garment (Posture Shirt[Formula: see text]; AlignMed, USA) on musculoskeletal wellness and health in the computer workplace.
Ninety-six computer users were evaluated. The Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire was completed. A functional assessment of posture, lung function, and grip strength was performed after wearing the Posture Shirt[Formula: see text] for 4 weeks. A training log was kept to track usage of the garment, as well as weekly sensations of fatigue, productivity, and energy level.
After 4 weeks, there was statistically significant improvement in forward shoulder and head posture, thoracic kyphosis, and grip strength. Improvements in spirometry measures did not meet statistical significance. Postural fatigue and muscular fatigue decreased by 21% and 29%, respectively, and energy level and productivity increased by 20% and 13%, respectively.
This prospective study demonstrated positive short-term impact of the Posture Shirt[Formula: see text] on both subjective and objective measures of posture, lung function, grip strength, fatigue, and productivity.
越来越多的证据表明,计算机用户患肌肉骨骼疾病的风险增加,尤其是那些涉及上肢的疾病,会带来巨大的经济成本和生产力损失。
本研究的目的是确定穿着动态弹性服装(姿势衬衫[公式:见正文];AlignMed,美国)对计算机工作场所中肌肉骨骼健康和健康状况的短期影响。
对96名计算机用户进行了评估。完成了手臂、肩膀和手部功能障碍(DASH)问卷。在穿着姿势衬衫[公式:见正文]4周后,进行了姿势、肺功能和握力的功能评估。记录训练日志以跟踪服装的使用情况,以及每周的疲劳感、生产力和能量水平。
4周后,前肩和头部姿势、胸椎后凸和握力有统计学上的显著改善。肺活量测定指标的改善未达到统计学意义。姿势疲劳和肌肉疲劳分别下降了21%和29%,能量水平和生产力分别提高了20%和13%。
这项前瞻性研究表明,姿势衬衫[公式:见正文]对姿势、肺功能、握力、疲劳和生产力的主观和客观指标都有积极的短期影响。
