![(a) Muscles activation level in 51.1 deg to upright 0 deg extension point-to-point movement for right-hand side muscles, generated by controller for 1.0 s duration. RA, EO, IO, ES, and LD stand for rectus abdominis, external oblique, internal oblique, erector spinae, and latissimus dorsi, respectively. (b) Experimental RMS filtered EMG activity of right rectus abdominis and lumbar erector spinae muscles, in 51.1 deg to upright 0 deg extension point-to-point movement with the same duration.
