Abstract

An automated adaptive muscle stimulation system and method are disclosed. The stimulation system includes at least one electrode assembly adapted to deliver a muscle stimulation signal to the tissue of a user, a sensor system adapted to detect a muscle response, and an electrical stimulation device operably coupled to the at least on electrode assembly and the sensor system, the electrical stimulation device including a control system operable to automatically diagnose at least one characteristic of a muscle from the detected muscle response and adjust at least one parameter of the muscle stimulation signal in response thereto to deliver an adjusted muscle stimulation signal. A dual mode muscle stimulation system adapted to accept first and second data sets and provide first and second levels of treatment data is also disclosed.

Claims

1. A stimulation system for automatically supplementing a voluntary muscle contraction with a muscle contraction caused by electrical stimulation, the system comprising:

an electrode assembly including at least one electrode configured to deliver electrical stimulation signals to a muscle of a user;

a speaker;

a sensor configured to detect contractions of the muscle; and

a control system operably connected to the electrode assembly, the speaker and the sensor, the control system to implement a preprogrammed electrostimulation program comprising a resting phase and a voluntary contraction phrase, the control system configured to;

during the resting phase, send an electrical test pulse through the at least one electrode to the muscle, the electrical test pulse configured to cause a muscle twitch;

detect, with the sensor, a first signal indicative of the muscle twitch caused by the electrical test pulse during the resting phase;

provide an auditory signal to the speaker to produce a sound signal to indicate a start of a voluntary contraction phase;

during the voluntary contraction phase, detect, with the sensor, a voluntary contraction of the muscle by detecting a second signal different from the first signal, the second signal indicative of a voluntary muscle contraction; and

responsive to detecting the voluntary contraction of the muscle, send an electrical stimulation signal through the at least one electrode to the muscle, the electrical stimulation signal configured to cause the muscle to contract such that the voluntary contraction and the electrical stimulation occur simultaneously during the voluntary contraction phase.

2. The system of claim 1, wherein the control system is configured to send the electrical test pulse in a resting phase between voluntary contractions of the muscle.

3. The system of claim 1, wherein the sensor is an accelerometer.

4. The system of claim 3, wherein the accelerometer is operable to detect an onset, a modification, or a disappearance of the muscle contraction.

5. The system of claim 1, wherein the sensor comprises a plurality of accelerometers.

6. The system of claim 1, wherein the sensor is a tension strain gauge.

7. The system of claim 1, wherein the control system is configured to enter a pause mode if no voluntary contraction is detected during a predetermined period.

8. The system of claim 1, wherein the control system is adapted to store at least one preprogrammed electrostimulation program.

9. The system of claim 8, wherein the preprogrammed electrostimulation program is selected from a program group consisting of a muscle fitness electrostimulation program, a muscle aesthetic electrostimulation program, a sport training electrostimulation program, a pain management electrostimulation program, a muscle rehabilitation electrostimulation program, and a vascular electrostimulation program.

10. A method for automatically supplementing a voluntary muscle contraction with a muscle contraction caused by electrical stimulation, the method comprising:

delivering, during a resting phase, an electrical test pulse to the muscle through the electrode, the electrical test pulse configured to cause a muscle twitch;

detecting a first signal indicative of the muscle twitch with a sensor;

providing an auditory signal to a speaker to produce a sound signal that indicates a start of a voluntary contraction phase;

monitoring, during a voluntary contraction phrase, a muscle of a user for a voluntary muscle contraction;

detecting the voluntary muscle contraction of the muscle by detecting a second signal different from the first signal, the second signal indicative of the voluntary muscle contraction; and

responsive to detecting the voluntary contraction of the muscle,

sending an electrical stimulation signal through an electrode to the muscle, the electrical stimulation signal configured to cause the muscle to contract such that the voluntary contraction and the electrical stimulation occur simultaneously.

11. The method of claim 10, further comprising applying at least one electrode to the user, the at least one electrode configured to deliver the electrical stimulation signal to the muscle.

12. The method of claim 10, further comprising applying at least one sensor to the user, the at least one sensor configured to detect a contraction of the muscle.

13. The method of claim 12, wherein the at least one sensor comprises an accelerometer.

14. The method of claim 10, further comprising delivering a preprogrammed electrostimulation program to the muscle.

15. The method of claim 14, wherein the preprogramed electrostimulation program is selected from a program group consisting of a muscle fitness electrostimulation program, a muscle aesthetic electrostimulation program, a sport training electrostimulation program, a pain management electrostimulation program, a muscle rehabilitation electrostimulation program, and a vascular electrostimulation program.

16. A stimulation system comprising:

a speaker;

a means for delivering an electrical stimulation signal to a muscle of a user;

a means for detecting contractions of the muscle; and

a control means operably connected to the means for delivering and the means for detecting, the control means configured to;

during a resting phase, send an electrical test pulse to the muscle through the means for delivering, the electrical test pulse configured to cause a muscle twitch;

detect, with the means for detecting, a first signal indicative of the muscle twitch caused by the electrical test pulse during the resting phase;

provide an auditory signal to the speaker to produce a sound signal to indicate a start of a voluntary contraction phase;

detect, with the means for detecting, a voluntary contraction of the muscle by detecting a second signal different from the first signal, the second signal indicative of a voluntary muscle contraction; and

responsive to detecting the voluntary contraction of the muscle, send an electrical stimulation signal through the means for delivering contractions to the muscle, the electrical stimulation signal configured to cause the muscle to contract such that the voluntary contraction and the electrical stimulation occur simultaneously.
