The purpose of this study was to determine the effect of current design recommendations (additional rest allowances) for static work on the development of temporary musculo-skeletal pains. The subjects were healthy, relatively fit young adults (16 men). Static work at 25% MVC was performed both in a commonly-used working posture and in a nontypical posture (overhead work). The ratios of work-to-rest corresponded to the ergonomical recommendations. Estimates of pain-perceptions concerning the neck, shoulders and back/trunk were recorded during the muscular exercise. The results show that under certain conditions (commonly-used working posture) the additional rest allowances render possible an exercise without musculoskeletal pains. During overhead work the development of temporary pain-perceptions is not inhibited by additional rest allowances. A revision of the current design recommendations for overhead work is suggested.
本研究的目的是确定当前针对静态工作的设计建议（额外的休息津贴）对临时性肌肉骨骼疼痛发展的影响。受试者为健康、相对健壮的年轻成年人（16名男性）。在常用工作姿势和非典型姿势（头顶作业）下均进行了25%最大自主收缩（MVC）的静态工作。工作与休息的比例符合人体工程学建议。在肌肉运动过程中记录了关于颈部、肩部和背部/躯干的疼痛感知估计值。结果表明，在某些条件下（常用工作姿势），额外的休息津贴使得在无肌肉骨骼疼痛的情况下进行锻炼成为可能。在头顶作业期间，额外的休息津贴并不能抑制临时性疼痛感知的发展。建议对当前头顶作业的设计建议进行修订。
