• Description:
  The prevalence of low back pain (LBP) increases with aging. Given the projected increase in the number of older individuals at workplace, management of occupational LBP will require an understanding of the reason(s) behind such increase in risk of LBP with aging. A recent study by Tafazzol et al. has shown that a reduction of lumbar contribution to a given angle of trunk flexion, as reflected in a reduction of lumbopelvic ratio (LPR), was associated with an increase in spinal loads. The objective of this study was to quantify age-related changes in LPR under fast and slow trunk flexion motions. On the basis of the suggested relationship between the LPR and spinal loads, it was hypothesized that, for a given task, the LPR of older versus younger individuals and faster versus slower motion paces will be smaller.
