Changes in segmental angles according to posture in two age groups. (A) Relatively larger changes in the first, second, and third segmental angles were observed when the posture of younger subjects changed from standing to supine. In contrast, relatively smaller changes were observed in the fourth and fifth segmental angles. Relatively larger changes were observed in the fourth and fifth segmental angles when sitting posture changed from 30° to 60°. (B) Insignificant changes in the first, second, and third segmental angles were detected in the older subjects. In contrast, various changes were observed in the fourth and fifth segmental angles according to postural changes.
