In- ing for stepping that incorporates partial body deed, the mechanics of walking can be mod- weight support. Several weeks after a complete lower thoracic spinal cord transection without deafferenta- tion, adult cats and other mammals have been trained on a treadmill so that their paralyzed hindlimbs fully support their weight, rhythmically step, and adjust their walking speed to that of the treadmill belt in a manner that is similar to normal locomotion. Changes in excitability are related to an increase in the GABA-synthesizing enzyme, GAD67, in the cord after spinal transection and glycine-mediated inhibition. After the nerve to the lateral gastrocnemius and soleus was cut, the lumbar locomotor circuits compensated for the induced gait deficit, a yield at the ankle during stance that produced a more forward placement of the foot and shortened the stance phase, by 8 days postneurectomy. Sensory feedback from cutaneous and proprioceptor inputs during stepping has a powerful affect on locomotor rhythm and muscle activation. The step phase transitions from stance to swing are triggered by afferent feedback related to extension at the hip and the unloading of leg extensor muscles. As this input wanes near the end of stance, it releases the flexor burst generating system and enables the initiation of the swing phase. Noxious input from one trodes at vertebral levels T-11 through L-1 and hip appeared to initiate the rhythmical locomo- measured surface EMG activity in five muscles tor activity.
