• Description:
  Age-related differences in lumbar contribution to the trunk motion in the sagittal plane were investigated. Sixty individuals between 20-70 years old in five gender-balanced age groups performed forward bending and backward return with slow and fast paces. Individuals older than 50 years old, irrespective of the gender or pace, had smaller lumbar contribution than those younger than this age. The lumbar contribution to trunk motion was also smaller in the female participants than in the male participants, and under fast pace than under the slow pace. Age-related differences in lumbar contributions suggest the synergy between the active and passive lower back tissues is different between those above and under 50 years old; differences that are likely to affect the lower back mechanics. Therefore, detailed modeling should be conducted in future to find the age-related differences in the lower back mechanics for tasks involving large trunk motion. [Description provided by NIOSH]
