a Apparatus setup for arm and leg cycling with cutaneous nerve stimulation. Hand and foot stimulations are indicated by lightning bolts. b Reflexes evoked by simultaneous SR + SP stimulation arm and leg cycling show nonlinear amplification (see arrow at left) which is absent during static contraction (see arrow at right). SR superficial radial nerve, SP superficial peroneal nerve, SR + SP simultaneous combined stimulation of SR and SP reflexes. Adapted from Nakajima et al. (2013a)
