The change in spinal configuration of the cervical, thoracic, and lumbar regions in relation to an amount of weight lifted was determined using videophotogrammetry. Fifteen healthy male subjects, 20-38 years of age, with no previous history of back pain participated in the study. The subjects lifted a crate containing 0, 10, and 20 kg weights using the straight-legs, bent-over-back method of lifting. The results showed that cervical and thoracic spinal segment configurations were not significantly influenced by the amount of weight lifted and that the mobility of the lumbar spinal segment was significantly decreased with increasing load (p = .03).
采用视频摄影测量法确定了颈椎、胸椎和腰椎区域的脊柱形态变化与所提举重量的关系。15名年龄在20至38岁之间、既往无背痛病史的健康男性受试者参与了该研究。受试者采用直腿弯腰的提举方法提起装有0、10和20千克重物的板条箱。结果表明，颈椎和胸椎节段的形态不受所提举重量的显著影响，而腰椎节段的活动度随着负荷增加而显著降低（p = 0.03）。
