Electrical neuromuscular stimulator for measuring muscle responses to electrical stimulation pulses
First Claim
1. An electrical neuromuscular stimulator for measuring muscle reactions generated by electrical stimulation pulses, comprisinga stimulator case, two electric cables each having at least one conductor wire, an electrical pulse generator arranged in said case of the stimulator for stimulating muscles, at least one pair of stimulation electrode structures adapted to be placed on an user'"'"'s skin on motor points of muscles to be stimulated, each electrode being connected to a first end of a respective one of said two electric cables, the other end of which is connected to the case to receive the electric pulses from the generator, and at least one measuring sensor sensitive to the muscle reactions caused by the electric stimulation pulses and arranged for transmitting electric measuring signals representative of said muscle reactions to an electronic means, for processing said measuring signals, said electronic means being housed in said case, wherein the sensor is mechanically connected to one of the electrodes or to the first end of one of the cables, and wherein at least one conductor wire per electric cable connects the respective electrode independently of the sensor.

Abstract
The electrical stimulator includes an electrical pulse generator arranged in a case, stimulation electrodes (7) to be placed on a user'"'"'s skin on the motor points of the muscles to be stimulated, each electrode (7) being connected to an electric cable (5) connector, the other end of the cable being connected in a removable manner to a signal input and/or output socket of the case for receiving the electric pulses, at least one sensor (11) for measuring the muscle reactions caused by the electric pulses, and electronic means in the case for receiving the measurements from the sensor. The sensor (11) is intrinsically linked to one of the electrodes (7) or to the connector (6). At least one conductor wire (15) of the cable connects the electrode (7) independently of the sensor (11).
The stimulator finds application in particular in the field of sports for the passive exercising of muscles stimulated by electric pulses, or in the re-education of atrophied muscles. In this case, the sensor (11) is used to provide data as to the reactivity of the stimulated muscles and their fatigue level. This data is seen on a display of the stimulator and is used to adjust the stimulation parameters manually or automatically.
