Abstract: Body weight supported treadmill training (BWSTT) is a therapy used to help individuals with a spinal cord injury (SCI) regain the ability to walk. During BWSTT, patients are supported by a harness over a treadmill while therapists provide manual assistance to move the patient's legs through a normal gait pattern. In order for BWSTT to be effective, it is believed that the therapy must replicate the forces and motions of normal gait. While this therapy is successful, not all patients respond in the same way and gait abnormalities exist following therapy. We collected kinematic and kinetic gait data from one individual with a SCI who has completed BWSTT. We tested the subject in the training environment at three speeds (selfselected (SS), 50% SS, and 150% SS) and at five levels of body weight support (BWS) (0%, 10%, 30%, 50%, and 70%). We analyzed lower extremity joint kinematics and kinetics, ground reaction forces, and the ankle-foot roll-over shape and compared with health subjects. The SCI subject lacked plantarflexion throughout most of the gait cycle, and his kinematics differed from healthy subjects during initial ground contact. The joint kinetics were variable between gait cycles, especially during midstance. The patient did not have an ankle-foot roll-over shape for the majority of the conditions. Since it is unknown how a person walks after regaining the ability to walk with BWSTT, this research is a step towards understanding and improving the outcomes from BWSTT.
