Biomechanics of Motion and Behaviour of Trans-Tibial Amputee During Gait

摘要

In the literature, several studies on Trans-tibial amputee (TTA) gait focused on kinematics of lower limbs variables. Former studies confirm the essential role of shoulder movement in the human gait. In the horizontal plane, a counter-rotation of pelvis and scapulae girdles occurred characterizing certain gait pathologies'. The purpose of this study is to enhance the compensation strategies of TTA individuals during walking, by analysing the kinematics of pelvis and scapulae girdle's movements in the sagittal and the horizontal planes. Twenty healthy human subjects (HS) and nineteen TTA participated in this study. A three-dimensional gait analysis with an optoelectronic VICON device were used. In the sagittal plane, the shoulder's movements are significantly higher during TTA gait. Two counter-rotations of the scapulae and pelvis girdles intervene in the early and in the middle of gait cycle. The kinematic analysis of the scapulae and pelvis girdles during walking showed that TTA have a specific character of gait.
