CLAIMS

1. Apparatus for neuromuscular stimulation, comprising:

(a) a module for receiving EMG signals from skin adjacent a muscle whose contraction is to be stimulated; and

(b) a module for supplying a succession of stimulation (STIM) pulses; and

(c) a controller configured to cause the EMG-receiving module to be operable during quiescent periods between successive pulses and to modulate the amplitude of stimulation pulses in the succession depending on a voluntary component of the received EMG signals.

2. The apparatus of claim 1, wherein the module for receiving EMG signals outputs to the controller the value of the voluntary EMG signals above a predetermined threshold.

3. The apparatus of claim 1 or 2, wherein the module for receiving EMG signals is operative between each pair of successive pulses.

4. The apparatus of claim 3, wherein the module for receiving EMG signals is operative substantially continuously between each pair of successive pulses.

5. The apparatus of claim 3 or 4, wherein the controller is configured to average the detected voluntary EMG signals to smooth amplitude modulation, whereby a user can achieve smooth muscle contraction.

6. The apparatus of any preceding claim, wherein the STIM pulses are symmetrical bipolar square-wave pulses and have phase duration which is short compared to the inter-pulse interval.

7. The apparatus of any preceding claim, wherein the controller is configured so that the STIM pulses do not exceed a maximum amplitude even on prolonged high values of the voluntary EMG signal.

8. The apparatus of any preceding claim, including circuits configured to reduce DC voltage at the electrodes during the inter-pulse interval and avoid swamping of the composite EMG signal.

9. A method for producing neuromuscular stimulation pulses, comprising:

(a) receiving EMG signals from skin adjacent a muscle whose contraction is to be stimulated;

(b) supplying a succession of stimulation (STIM) pulses;

(c) operating the EMG-receiving module during quiescent periods between successive pulses; and

(d) modulating the amplitude of stimulation pulses in the succession depending on the detected voluntary component of the received EMG signals.

10. The method of claim 9, wherein the EMG signals are received and the stimulation pulses are supplied via skin electrodes.

11. The method of claim 9, wherein the same electrodes receive the EMG signals and supply the stimulation pulses.

12. The method of claim 9, wherein one pair of electrodes receives the EMG signals and another pair of electrodes supplies the stimulation pulses.

13. A method for supplying neuromuscular stimulation pulses to a subject, comprising:

(a) receiving EMG signals from the subject adjacent a muscle whose contraction is to be stimulated;

(b) supplying a succession of stimulation (STIM) pulses to the muscle to be stimulated;

(c) operating the EMG-receiving module during quiescent periods between successive pulses; and

(d) modulating the amplitude of stimulation pulses supplied to the subject in the succession depending on the detected voluntary component of the EMG signals.

14. The method of claim 13, wherein the EMG signals and the STEVI pulses are received and supplied through the same pair of electrodes.

15. The method of claim 13, wherein the EMG signals are received through a first pair of electrodes and the STEVI pulses are supplied through a second pair of electrodes.

16. The method of any of claims 13-15 wherein the EMG signals are received and the STEVI pulses are supplied through skin electrodes.

17. The method of any preceding claim, wherein the subject is a stroke or paresis patient.

18. The method of any of claims 13-16, wherein the subject is a patient suffering from cerebral palsy, incontinence or muscle atrophy.

19. The method of any of claims 13-16, operable in sports clinical mode for muscle growth and endurance.

20. The method of any of claims 13-19, wherein modulation is in real time during supply of stimulation pulses whereby the subject is given a sensation of natural muscle control and/or the possibility for greater precision of neuromuscular control.
