Objective: Comparing the anterior postural alignment of the body segments between standing and supine position and the degree of asymmetry in healthy young adults.
Population and Methods: The research was conducted at the Faculty of Medicine in Tel Aviv University. Thirty-four healthy participants were evaluated in standing and supine positions using photogrammetric method. Seven postural variables were analyzed using the software SAPO. Paired T-test was used to compare the two positions.
Results: The results demonstrated that in the supine position, the degree of asymmetry for the head (P < .02) increased. However, the upper trunk showed an increased degree of symmetry (P < .02) in supine position compared to the standing position.
Conclusions: Our results indicate that the supine position improves trunk symmetrical alignment. Our results support recent studies on scoliotic patients. These results might have clinical implications for treating asymmetric patients. To better understand the effect of gravity and body position on asymmetrical postural alignment, more studies are needed.
