Musculoskeletal disorders (MSDs) can be prevented by avoiding trauma caused by poor posture, compression, force, and repetition. Neutral postures are recommended to avoid MSDs.
This study introduces Mouse With Your Arm™ (MWYA) methodology which promotes sitting back in a chair, using the chair's armrest for forearm support at relaxed elbow height, matching surface and armrest height, and keeping the mouse on the surface edge. This position allows optimal task chair use, facilitates movement and neutral postures, avoids compression and contact stress, and is effective in mitigating MSDs.
MWYA was applied and measured in the field for more 23 years providing over 3,500 individualized assessments to integrate a participant's unique characteristics, reported health concerns, tasks, tools, and environment to achieve and sustain whole-body neutral and comfortable working postures.
Previous research has consistently recommended use of forearm support by a desk, apparatus, or wrist rest, and resulted in non-neutral, static postures and measured health consequences. By using armrests for support, MWYA avoids the potential of MSDs as can be caused by these previously endorsed postures.
By applying the five MWYA principles, computer users comprehend neutral posture and put forth the effort essential to creating healthy human computer relationships.
肌肉骨骼疾病（MSDs）可通过避免因不良姿势、压迫、用力和重复动作所导致的创伤来预防。建议采用中立姿势以避免肌肉骨骼疾病。
本研究介绍了“手臂支撑鼠标法”（MWYA），该方法提倡坐在椅子上向后靠，将椅子扶手用于在放松的肘部高度支撑前臂，使桌面与扶手高度相匹配，并将鼠标置于桌面边缘。此姿势能实现任务椅的最佳使用，便于活动并保持中立姿势，避免压迫和接触压力，且能有效减轻肌肉骨骼疾病。
“手臂支撑鼠标法”已在实际场景中应用和测量了23年以上，提供了超过3500次个性化评估，以整合参与者的独特特征、报告的健康问题、任务、工具和环境，从而实现并维持全身中立且舒适的工作姿势。
先前的研究一直建议使用桌子、器具或腕托来支撑前臂，这导致了非中立的静态姿势以及可测量的健康后果。通过使用扶手进行支撑，“手臂支撑鼠标法”避免了这些先前认可的姿势可能导致的肌肉骨骼疾病风险。
通过应用“手臂支撑鼠标法”的五项原则，计算机用户理解了中立姿势，并付出努力来建立健康的人机关系。
