Segmental contribution to whole-body angular momentum during stepping in healthy young and old adults

Abstract Recent evidence suggests that during volitional stepping older adults control whole-body angular momentum (H) less effectively than younger adults, which may impose a greater challenge for balance control during this task in the elderly. This study investigated the influence of aging on the...
