Abstract :
Isometric torques were generated about the knee joint by microstimulation of the cat lumbar L6 spinal cord. Stimulation via a single microelectrode in the ventral part of the L6 spinal cord produced large knee joint extension torques. The extension torques were influenced by stimulus intensity, frequency and pulsewidth. Certain stimulation parameters (100 μA intensity, 40 Hz frequency and 0.20 ms pulsewidth) appear optimal for mapping the lumbosacral spinal cord based on the knee joint torque responses that are produced
