Figure 4From: Implanted functional electrical stimulation: case report of a paraplegic patient with complete SCI after 9 yearsRecruitment curve of the left QU (solid line) and right QU (dot line) at 25 Hz, pulse width 502.4 μs. Normalized to the maximum torque obtained at the maximum intensity level (3.15 mA). Intensity varies through 8 steps 0.4, 0.8, 1.2, 1.6, 2, 2.4, 2.8, 3.15 mA with 0.5 s on 0.5 s off to limit fatigue.Back to article page
