The kinematics of the body center mass (bCoM) may provide crucial information supporting rehabilitation process people with transfemoral amputation. use magneto-inertial measurement units (MIMUs) is promising as it allow in-the-field bCoM motion monitoring. Indeed, acceleration might be obtained by fusing estimated accelerations segments’ centers (sCoM), formers being computed from measured seg...

Introduction In any discussion of the development of tech­ nology as applied to the rehabilitation of the above-the-knee amputee , we must first acknow­ ledge the many contr ibut ions of European pioneers in this field. In Europe the needs resulting from World War I resulted in greatly accelerated research and development in the field of prosthetics technology during the next three decades. Thi...

This study describes the injuries, complications, functional limitations, and rehabilitative needs of amputees managed at Walter Reed Army Medical Center during the Persian Gulf conflict (1991). Fourteen amputees were treated sustaining 21 amputations with 18 lower-limb and 3 upper-limb amputations. In six casualties there were multiple amputations. Battle injuries were the cause in 79%. Nerve ...

We seek to improve balance recovery in amputee gait by taking advantage of the advent of active leg prostheses. Toward this goal, we use inspiration from biology to identify reflex-like control strategies that stabilize gait, refine these strategies in simulations of amputee locomotion, and evaluate the resulting controllers in experiments with human subjects wearing custom prototypes of active...

1 Chief, Orthopaedic Service, Veterans Administration Center, Wilshire and Sawtelle Blvds., Los Angeles, Calif. 90073. The geriatric amputee not infrequently suffers from debilitating diseases other than the one which caused his amputation. These affect his prognosis for life, for retention of his other leg, his ability to use a prosthesis, the performance of activities of daily living, his par...

Transfemoral prostheses have traditionally sought to emulate symmetry in their designs. Using a symmetric prosthesis for a physically asymmetric unilateral transfemoral amputee typically causes asymmetric gait patterns. This research study investigates the effects of prostheses with lower knee heights than the intact knee and a pilot study of the combined effects of adding distal mass with lowe...
