High muscle strength is considered relevant for preventing musculoskeletal disorders and long-term sickness absence. However, prospective studies on the association between muscle strength and future musculoskeletal disorders and long-term sickness absence are few and show contrasting results.
To investigate the association between low muscle strength and future musculoskeletal disorders and long-term sickness absence.
Muscle strength in trunk flexion and extension, shoulder elevation and abduction as well as handgrip was recorded from a representative sample of Danish workers (n = 421) in 1995. Musculoskeletal disorders were reported 5 years later (in 2000). Information on long-term sickness absence was retrieved from a register of social transfer payments in the period 1996-2007.
Regression analyses adjusted for age, gender, smoking, body mass index and physical work demands showed that workers with low muscle strength (the lowest quartile) of trunk extension and flexion, shoulder elevation and abduction and handgrip did not have a significantly increased risk for future musculoskeletal disorders or long term sickness absence compared with stronger workers.
Low muscle strength does not seem to be a good predictor for musculoskeletal disorders and long-term sickness absence in the general working population.
高肌肉力量被认为与预防肌肉骨骼疾病和长期病假有关。然而，关于肌肉力量与未来肌肉骨骼疾病和长期病假之间关联的前瞻性研究很少，且结果相互矛盾。
调查低肌肉力量与未来肌肉骨骼疾病和长期病假之间的关联。
1995 年，从丹麦工人的代表性样本中记录了躯干屈伸、肩部抬高和外展以及手握力的肌肉力量。5 年后（2000 年）报告了肌肉骨骼疾病。1996-2007 年期间，从社会转移支付登记处检索了长期病假信息。
调整年龄、性别、吸烟、体重指数和体力工作需求的回归分析表明，与较强壮的工人相比，躯干伸展和弯曲、肩部抬高和外展以及手握力较弱的工人（最低四分位数）未来患肌肉骨骼疾病或长期病假的风险没有显著增加。
在一般工作人群中，低肌肉力量似乎不是肌肉骨骼疾病和长期病假的良好预测指标。
