Psychosocial stress is assumed to contribute to musculoskeletal disorders, particularly neck and shoulder pain. Experimental studies show that mental stress induces a significant increase in muscle tension in the trapezius muscle and several explanatory models have been proposed in order to understand the mechanisms linking low sustained muscle tension to musculoskeletal disorders. Recently, it has been demonstrated that the same motor units are activated by mental stress as by physical demands, which means that mental stress may keep low threshold motor units active also during breaks at work and off the job. In the modern society, lack of rest and recovery seems even more important for health than the magnitude of stress and physical demands during work.
心理社会压力被认为会导致肌肉骨骼疾病，尤其是颈部和肩部疼痛。实验研究表明，精神压力会导致斜方肌的肌肉张力显著增加，并且已经提出了几种解释模型，以了解将低持续肌肉张力与肌肉骨骼疾病联系起来的机制。最近，已经证明，与身体需求一样，精神压力也会激活相同的运动单位，这意味着精神压力可能会使低阈值运动单位在工作间隙和下班后也保持活跃。在现代社会，缺乏休息和恢复对健康的影响似乎比工作期间的压力和身体需求的大小更为重要。
