Uncoordinated muscular response to microsecond electrical pulses is a manifestation of simultaneous multiple spinal reflexes

Two sets of experiments were performed to show the possibility of inducing temporary muscular incapacitation. In the first set of experiments, individual major nerves (femoral, saphenous and ulnar) were surgically dissected and isolated with electrically insulating sheets. In the second set of experiments, similar electrical pulses were used to stimulate the chest area through electrodes inserted under the skin. Results show that a spastic muscular activity requires a stimulation of both sensory and motor nerves, simultaneously, with electrical stimuli of certain characteristics.
