Abstract

A device ( 103 ) for applying an electrical stimulation to one or more muscles of the mouth of the user, the device ( 103 ) includes one or more electrodes ( 132, 133 ) for applying electrical stimulation to one or more muscles of the mouth of a user and a sensor ( 140 a, 140 b, 141 a, 141 b ) for determining the muscle tone of the tongue of the user. Also disclosed are methods and systems for determining a stimulation plan.

Claims (33)

1. An apparatus for applying an electrical stimulation to the mouth of an awake user to train the muscles of the mouth, the apparatus comprising:

a device comprising one or more electrodes for applying electrical stimulation to train one or more muscles of the mouth of the user during an awake state, the electrical stimulation configured to increase muscle tone of the one or more muscles of the mouth during sleep;

a pressure sensor for determining the awake muscle tone of the tongue of the user;

a controller configured to provide output of the user while the user is operating the apparatus and alter the electrical stimulation based on an input from the user; and

a switch operable to switch the device from a stimulation mode to a test mode and vice versa, wherein in the test mode the controller is configured to guide the user to apply tongue pressure to the pressure sensor using a user interface, further wherein the controller determines muscle tone in the user based on the applied tongue pressure.

2. The apparatus according to claim 1 , wherein the device comprises a mouthpiece for locating in a user's mouth.

3. The apparatus according to claim 1 , wherein the device comprises a pair of arms connected together at a connecting portion and extending away from one another.

4. The apparatus according to claim 3 , wherein the sensor is located on the arms.

5. The apparatus according to claim 1 , wherein the device comprises flanges for overlying at least a portion of the dorsal or sublingual surface of the user's tongue.

6. The apparatus according to claim 5 , wherein the sensor is located on the flanges.

7. The apparatus according to claim 1 , wherein the switch is configured to be controlled by the awake user.

8. The apparatus according to claim 1 , wherein the sensor is selected from one or more of a pressure sensor, a microphone, an optical transmission sensor, an impedance sensor or an optical reflectance sensor.

9. The apparatus according to claim 1 , wherein the sensor comprises an electrical signal sensor.

10. The apparatus according to claim 1 , further comprising memory to hold data relating to one or both of the electrical stimulation which has been applied to said one or more muscles and/or data relating to the output of the sensor.

11. The apparatus according to claim 1 , further comprising a processor to process data relating to one or both of the electrical stimulation which has been applied to said one or more muscles and/or data relating to the output of the sensor.

12. The apparatus according to claim 11 , wherein the processor is operable to control the controller based on data processed by the processor.

13. The apparatus according to claim 1 , wherein the sensor is operable to provide data when in the test mode and not operable to provide data when in the stimulation mode.

14. A method of providing a stimulation plan to train one or more muscles of the mouth in an awake user, the method comprising;

locating a mouthpiece having one or more electrodes in the mouth of the awake user;

guiding the awake user to apply tongue pressure to a pressure sensor, wherein the user is guided by a user interface when the mouthpiece is in a test mode;

determining the muscle tone of the tongue of the mouth of the awake user based on the pressure applied by the tongue to the pressure sensor;

generating a stimulation plan to stimulate the one or more muscles of the mouth of the user during an awake state, the stimulation plan generated based on the determined muscle tone; and

switching the mouthpiece from the test mode to a stimulation mode to activate the stimulation plan in the awake user during the awake state, the stimulation plan configured to increase resting muscle tone of the one or more muscles of the mouth.

15. The method according to claim 14 , further comprising providing user-related data, wherein the user-related data is one or more of age, weight, height, body mass index (BMI).

16. A method of altering a stimulation plan to train one or more muscles of the mouth in an awake user, the method comprising;

providing a stimulation plan for electrically stimulating one or more muscles of a tongue of the user while the user is in an awake state;

locating a mouthpiece in the mouth of the awake user;

guiding the awake user, with a user interface, to apply tongue pressure to a pressure sensor when the mouthpiece is in a test mode;

determining the muscle tone of one or more muscles of the tongue of the awake user based on the pressure applied by the tongue to the pressure sensor;

adjusting the stimulation plan according to the determined muscle tone of the awake user; and

switching the mouthpiece from the test mode to a stimulation mode to activate the stimulation plan for the awake user while the user is in the awake state.

17. The method according to claim 16 , wherein adjusting the stimulation plan comprises comparing the determined muscle tone to a desired or expected muscle tone and adjusting the stimulation plan accordingly.

18. The method according to claim 16 , wherein switching the mouthpiece from the test mode to a stimulation mode comprises switching by the awake user while the user is in the awake state.
