Effect of Aging on the Trunk and Lower Limb Kinematics during Gait on a Compliant Surface in Healthy Individuals

Older adults have a smaller effective living space and reduced physical activity. Although walking ability in various spaces is necessary to maintain healthy life high level of activity, it unclear how older adapt compliant surfaces when walking. The purpose this study was determine the differences trunk lower limb kinematics while on versus surface, effect aging these kinematic changes. Twenty-two individuals (aged from 20–80 years) were asked walk along 7-m walkway at comfortable speed surface. Gait measured using three-dimensional camera-based motion analysis system. We found that knee hip flexion ankle plantarflexion angles early stance phase thoracic angle throughout gait cycle significantly increased surface change angle, cadence between correlated with age. Therefore, use higher navigate surfaces.
