Figure 4.
Effects of FES on seated stability and active pulling. Both mean and peak resistance to anteriorly directed forces applied isokinetically at 10°/sec (a) increased with FES and allowed larger moments to be resisted prior to loss of balance and forward hip and trunk flexion. Stiffening the hip and trunk with stimulation allowed significantly larger maximal moments to be generated voluntarily by the subject during underhanded pulling motions at all speeds tested (b)
