It has been well known that complex tasks such as walking and arm reaching can be
achieved by the coordination of the trunk and pelvis. However, understanding of
the effect of aging on the coordination of the trunk and pelvis during axial
trunk rotation is still lacking.
The present study examined relative phase of the
trunk and pelvis during axial trunk rotation, and compared it between young and
older groups. 22 healthy young (age: 23.9+/-4.6, gender: 11 male and 11 female)
and 22 healthy elderly (age: 68.4+/-4.9, gender: 11 male and 11 female)
individuals participated in the experiment and performed axial trunk rotation.
Relative phase between the trunk and pelvis was calculated based on the angular
displacements of the two segments. The results demonstrated age-related changes
in coordination pattern of the trunk and pelvis during axial trunk rotation.
