Insertion of electrodes and setting of gait rhythm stimulation. Each rat was anesthetized and secured to a platform (a). Needle electrodes (down arrow) were percutaneously inserted into the tibialis anterior (TA) muscle and gastrocnemius (Gc) of both limbs (b). With the rat awake and the trunk secured, gait rhythm was stimulated using stimulation electrodes and filmed using four charge-coupled device cameras (a)
