Lower extremity eccentric motor control is is critically important for locomotor function but is impaired after spinal cord injury (SCI). Even after treadmill training, preliminary evidence indicates that eccentric deficits persist among individuals with SCI. This proposal aims to characterize eccentric motor control of the muscles about the hip during locomotion and evaluate the efficacy of downhill gait training at slow speeds as an intervention to improve eccentric function of the hip joint during walking.
