Figure 3From: Stance controlled knee flexion improves stimulation driven walking after spinal cord injuryAverage (± 1 std. dev.) sagittal plane trunk orientation and upper extremity (UE) vertical force across experimental conditions: VIKM-HNP (solid line) and FNS-only (dashed line). Trunk orientation of 0° is vertical, positive is forward tilt. UE force was normalized by user body weight. Vertical black line indicates transition from stance to swing phase.Back to article page
