Abstract

A system and method for skeletal muscle stimulation is provided for increasing muscle mass by stimulating a muscle in an optimal condition through a stimulus signal from an electrical stimulation device disposed at a stimulation position.

First claim

What is claimed is:

1. An apparatus for muscle stimulation, the apparatus comprising:
an electrical stimulation device, comprising an electrode in contact with a muscle, and configured to
wirelessly receive position information from a terminal device,
use the electrode to measure an electromyogram (EMG) signal at a stimulation position; and
determine whether the EMG signal is within a tolerance or outside of the tolerance,
wherein, in response to the EMG signal being determined to be outside the tolerance, in response to a distribution of the EMG signal being greater than or equal to a reference distribution value for a muscle in a contracted state, the electrical stimulation device is configured to output information to the terminal device to adjust the position at which the electrode is in contact with the muscle, and
wherein, in response to the EMG signal being determined to be within the tolerance, in response to a distribution of the EMG signal being less than the reference distribution value for the muscle in the contracted state, the electrical stimulation device is configured to communicate with the terminal device to receive a pattern from the terminal device with respect to the stimulation position, and output a stimulus signal to the stimulation position, based on the pattern.

2. The apparatus of claim 1 , wherein the electrical stimulation device is further configured to output the stimulus signal, in response to the EMG signal.

3. The apparatus of claim 1 , wherein the electrical stimulation device is wireless.

4. The apparatus of claim 1 , wherein the electrical stimulation device comprises:
a power supply configured to generate the stimulus signal; and
a differential amplifier configured to measure the EMG signal.

5. The apparatus of claim 1 , wherein in response to the electrical stimulation device outputting information to the terminal device to adjust the position at which the electrode is in contact with the muscle, the terminal device outputs guide information to a user, that enables the user to attach the electrode to the stimulation position.

6. The apparatus of claim 5 , wherein the guide information comprises an image or an illustration.

7. The apparatus of claim 5 , wherein the guide information corresponds to a muscle that is identified in response to the input from the user.

8. The apparatus of claim 7 , wherein the terminal device is configured to provide a pattern of applying the stimulus signal for contracting or relaxing the muscle.
