Anteroposterior (A) and lateral (B) view of two 8-contact leads. The tips of the leads were placed at the bottom of the T7 vertebral body. This image represents the final placement of the leads. Differential target multiplexed stimulation consisted of a base signal (frequency, 50 Hz; pulse width 200 mus) and other 3 programs of prime signals (frequency, 300 Hz; pulse width 170 mus).
