From: Stance controlled knee flexion improves stimulation driven walking after spinal cord injury
Average (± 1 std. dev.) vertical and horizontal ground reaction forces (GRFs) and external knee moment across experimental conditions: VIKM-HNP (solid line) and FNS-only (dashed line). GRFs (given as percentage body weight) and external knee moment (Nm/kg) are normalized by body weight and body weight plus weight of the VIKM orthosis for FNS-only and VIKM-HNP conditions, respectively. Positive values of external moment are extension, negative are flexion.
