title: Lowered or increased cutaneous sensitivity during movement depends on stimulus intensity.
abstract: The effect of active and passive finger movement on cutaneous sensitivity to nonpainful electric stimulation was studied in 7 healthy human subjects. Active and passive finger movement produced a suppression of threshold stimuli, whereas the amplitude discrimination of suprathreshold stimuli was enhanced during passive but not active movement.
