Figure 4.
Feasible posture maps for best 8-channel configurations. Gray area: feasible postures using select muscles. Black boundary: feasible postures available using complete muscle set with spinal cord injury parameters. Small figures represent directions of posture movement. “+” = nominal posture, “%” = percentage of feasible postures within black boundary, AM = adductor magnus, EO = external oblique, ES = erector spinae, G = gluteus maximus, H = hamstrings, IO = internal oblique, IP = iliopsoas, PM = psoas major, RA = rectus abdominis.
