[Purpose] The purpose of this study was to investigate the effect of aging on respiratory synergy, through the comparison of an elderly group and a young group, to help further understanding of postural control in the elderly. [Subjects and Methods] Ten community-dwelling elderly subjects and ten young subjects performed standing under two different respiratory conditions: quiet breathing and apnea. Center of foot pressure displacement and joint angular movements of the head, trunk, pelvis, hips, knees and ankles were measured. [Results] The results of this study showed that the elderly group had a respiratory synergy different from that of the young group. The elderly group in quiet stance used significantly more hip and pelvis movements when compensating for respiratory disturbance than standing with apnea, while the young group used significantly more whole body segments. There were no differences in angular displacements in the quiet stance between the elderly and the young groups. [Conclusion] The elderly group demonstrated a respiratory synergy pattern different from that of the young group. The findings indicate that aging changes the respiratory synergy pattern and this change is not due to decreased functioning of the ankle joint alone.
