Abstract

Methods, devices and systems for recovering motor control of an area in the body of a patient affected by a neurological disorder. A device vibrotactilely stimulates a substitute site for the affected area thereby recovering the motor control of the affected area. The stimulation provided by the device is volitionally controlled by the patient.

Claims

1. A method for recovering motor control of an area in the body of a patient affected by a neurological disorder, the method comprising vibrotactile stimulating a substitute site for said area thereby recovering the motor control of said affected area, wherein said stimulating of said substitute site is volitionally controlled by said patient, wherein said affected area is the area of the body responsible for swallowing, wherein said area responsible for swallowing is the oropharyngeal area and said substitute site is the area of the throat over the larynx, wherein said patient volitionally controls said stimulating by activating a vibrotactile stimulator attached on the throat over the larynx of said patient, wherein said recovered motor control is volitional swallowing, wherein vibrotactile stimulating the substitute site includes rotating a vibrator motor.

2. The method of claim 1, wherein said neurological disorder is related to a condition selected from the group consisting of brain trauma, stroke, Parkinson'"'"'s Disease, cerebral palsy, a tumor, birth defect, multiple sclerosis, ALS, supranuclear palsy and brain hemorrhage.

3. The method of claim 1, wherein vibrotactile stimulating the substitute site includes stimulating at a frequency between about 50 Hz and about 2,000 Hz.

4. The method of claim 1, wherein vibrotactile stimulating the substitute site includes stimulating at a frequency between about 20 Hz and about 1,000 Hz.

5. The method of claim 1, wherein the vibrotactile stimulator is configured to produce vibration useful for treatment of dysphagia.

6. The method of claim 1, wherein vibrotactile stimulating the substitute site includes rotating one vibrator motor.

7. The method of claim 1, wherein vibrotactile stimulating the substitute site includes rotating a plurality of vibrator motors.

8. The method of claim 1, wherein activating the vibrotactile stimulator includes pushing a button.

9. The method of claim 8, wherein activating the vibrotactile stimulator includes pushing the button coupled to a utensil.

10. The method of claim 1, wherein vibrotactile stimulating the substitute site includes stimulating at a frequency between about 30 Hz and about 60 Hz.

11. The method of claim 1, wherein vibrotactile stimulating the substitute site includes stimulating at a frequency between about 30 Hz and about 50 Hz.

12. The method of claim 1, wherein vibrotactile stimulating the substitute site is for a duration between about 2 seconds and about 6 seconds.

13. A method for recovering motor control of an area in the body of a patient affected by a neurological disorder, the method comprising vibrotactile stimulating a substitute site for said area thereby recovering the motor control of said affected area, wherein said stimulating of said substitute site is volitionally controlled by said patient, wherein said affected area is the area of the body responsible for swallowing, wherein said area responsible for swallowing is the oropharyngeal area and said substitute site is the area of the throat over the larynx, wherein said patient volitionally controls said stimulating by activating a vibrotactile stimulator attached on the throat over the larynx of said patient immediately before a volitional attempt to swallow, wherein said recovered motor control is volitional swallowing, wherein vibrotactile stimulating the substitute site includes rotating a vibrator motor.

14. The method of claim 13, wherein activating the vibrotactile stimulator is between 1 second and 10 seconds before the volitional attempt to swallow.

15. The method of claim 13, wherein activating the vibrotactile stimulator is between 0.1 seconds and 1 second before the volitional attempt to swallow.

16. The method of claim 13, wherein activating the vibrotactile stimulator is between 0.2 seconds and 0.5 seconds before the volitional attempt to swallow.

17. The method of claim 13, wherein activating the vibrotactile stimulator is between 0.2 seconds and 0.4 seconds before the volitional attempt to swallow.

18. The method of claim 13, wherein said neurological disorder is related to a condition selected from the group consisting of brain trauma, stroke, Parkinson'"'"'s Disease, cerebral palsy, a tumor, birth defect, multiple sclerosis, ALS, supranuclear palsy and brain hemorrhage.

19. The method of claim 13, wherein vibrotactile stimulating the substitute site includes stimulating at a frequency between about 50 Hz and about 2,000 Hz.

20. The method of claim 13, wherein vibrotactile stimulating the substitute site includes stimulating at a frequency between about 20 Hz and about 1,000 Hz.

21. The method of claim 13, wherein vibrotactile stimulating the substitute site includes stimulating at a frequency between about 30 Hz and about 60 Hz.

24. The method of claim 13, wherein vibrotactile stimulating the substitute site includes rotating one vibrator motor.

25. The method of claim 13, wherein vibrotactile stimulating the substitute site includes rotating a plurality of vibrator motors.

26. The method of claim 13, wherein activating the vibrotactile stimulator includes pushing a button.

27. The method of claim 13, wherein vibrotactile stimulating the substitute site is for a duration between about 2 seconds and about 6 seconds.

28. A method for recovering motor control of an area in the body of a patient affected by a neurological disorder, the method comprising vibrotactile stimulating a substitute site for said area thereby recovering the motor control of said affected area, wherein said stimulating of said substitute site is volitionally controlled by said patient, wherein said affected area is the area of the body responsible for swallowing, wherein said area responsible for swallowing is the oropharyngeal area and said substitute site is the mucosa in the upper airway, wherein said patient volitionally controls said stimulating by activating a vibrotactile stimulator attached on the throat over the larynx of said patient, wherein said recovered motor control is volitional swallowing, wherein vibrotactile stimulating the substitute site includes rotating a vibrator motor.

29. The method of claim 28, wherein said neurological disorder is related to a condition selected from the group consisting of brain trauma, stroke, Parkinson'"'"'s Disease, cerebral palsy, a tumor, birth defect, multiple sclerosis, ALS, supranuclear palsy and brain hemorrhage.

30. The method of claim 28, wherein vibrotactile stimulating the substitute site includes stimulating at a frequency between about 50 Hz and about 2,000 Hz.
