To investigate the longitudinal relation between physical capacity (isokinetic lifting strength, static endurance of the back, neck, and shoulder muscles, and mobility of the spine) and low back, neck, and shoulder pain.
In this prospective cohort study, 1789 Dutch workers participated. At baseline, isokinetic lifting strength, static endurance of the back, neck, and shoulder muscles, and mobility of the spine were measured in the pain free workers, as well as potential confounders, including physical workload. Low back, neck, and shoulder pain were self-reported annually at baseline and three times during follow up.
After adjustment for confounders, Poisson generalised estimation equations showed an increased risk of low back pain among workers in the lowest sex specific tertile of performance in the static back endurance tests compared to workers in the reference category (RR = 1.42; 95% CI 1.19 to 1.71), but this was not found for isokinetic trunk lifting strength or mobility of the spine. An increased risk of neck pain was shown for workers with low performance in tests of isokinetic neck/shoulder lifting strength (RR = 1.31; 95% CI 1.03 to 1.67) and static neck endurance (RR = 1.22; 95% CI 1.00 to 1.49). Among workers in the lowest tertiles of isokinetic neck/shoulder lifting strength or endurance of the shoulder muscles, no increased risk of shoulder pain was found.
The findings of this study suggest that low back or neck endurance were independent predictors of low back or neck pain, respectively, and that low lifting neck/shoulder strength was an independent predictor of neck pain. No association was found between lifting trunk strength, or mobility of the spine and the risk of low back pain, nor between lifting neck/shoulder strength or endurance of the shoulder muscles and the risk of shoulder pain.
研究身体能力（等速举重力量、背部、颈部和肩部肌肉的静态耐力以及脊柱活动度）与腰背痛、颈痛和肩痛之间的纵向关系。
在这项前瞻性队列研究中，1789名荷兰工人参与其中。在基线时，对无疼痛的工人测量其等速举重力量、背部、颈部和肩部肌肉的静态耐力以及脊柱活动度，以及潜在混杂因素，包括体力工作量。在基线时以及随访期间三次，由工人自我报告腰背痛、颈痛和肩痛情况。
在对混杂因素进行调整后，泊松广义估计方程显示，与参考组的工人相比，在静态背部耐力测试中处于最低性别特异性三分位数表现的工人患腰背痛的风险增加（相对危险度 = 1.42；95%可信区间1.19至1.71），但在等速躯干举重力量或脊柱活动度方面未发现这种情况。在等速颈部/肩部举重力量测试表现不佳的工人（相对危险度 = 1.31；95%可信区间1.03至1.67）和静态颈部耐力测试表现不佳的工人（相对危险度 = 1.22；95%可信区间1.00至1.49）中，显示患颈痛的风险增加。在等速颈部/肩部举重力量或肩部肌肉耐力处于最低三分位数的工人中，未发现患肩痛的风险增加。
本研究结果表明，背部或颈部耐力分别是腰背痛或颈痛的独立预测因素，而颈部/肩部举重力量低是颈痛的独立预测因素。未发现躯干举重力量、脊柱活动度与腰背痛风险之间存在关联，也未发现颈部/肩部举重力量或肩部肌肉耐力与肩痛风险之间存在关联。
