Figure 3From: The effect of age on sagittal plane profile of the lumbar spine according to standing, supine, and various sitting positionsChanges in lumbar lordosis according to posture in the two age groups. Lumbar lordosis decreased as posture changed from standing to supine, and as sitting angle increased (from 30° to 90°) in the young and older groups. In the young group, lumbar lordotic angles were relatively greater when posture changed from standing to supine and from sitting at 30° to sitting at 60°.Back to article page
