Abstract

A hand tremor treatment device that includes a ventral pad including a ventral vibration-inducing device and a ventral compression-inducing device, a dorsal pad including a dorsal vibration-inducing device and a dorsal compression-inducing device, a lateral strap, a medial strap, and a controller. The device is configured to be worn on the wrist and is configured to detect a hand tremor onset and in response induce compression via at least one selected from the ventral compression-inducing device and the dorsal compression-inducing device and to induce vibration via at least one selected from the ventral vibration-inducing device and the dorsal vibration-inducing device.

First claim

1 . A hand tremor treatment device, comprising
a ventral pad configured to be positioned on a ventral surface of a wrist of a subject and including a ventral vibration-inducing device and a ventral compression-inducing device; a dorsal pad configured to be positioned on a dorsal surface of a wrist of the subject and including a dorsal vibration-inducing device and a dorsal compression-inducing device; a lateral strap connecting the ventral pad and the dorsal pad and configured to pass over a lateral surface of a wrist of the subject; a medial strap connecting the ventral pad and the dorsal pad and configured to pass over a medial surface of a wrist of the subject; and a controller configured to detect a hand tremor onset and in response to detecting the hand tremor onset induce compression via at least one selected from the ventral compression-inducing device and the dorsal compression-inducing device and to induce vibration via at least one selected from the ventral vibration-inducing device and the dorsal vibration-inducing device.

2 . The hand tremor treatment device of claim 1 , wherein the lateral strap and the medial strap are flexible.

3 . The hand tremor treatment device of claim 1 , wherein at least one selected from the group consisting of the lateral strap and the medial strap is adjustable to securely conform to a wrist of a subject.

4 . The hand tremor treatment device of claim 1 , wherein ventral compression-inducing device and the dorsal compression-inducing device each include an inflatable airbag.

5 . The hand tremor treatment device of claim 4 , wherein the inflatable airbag includes a pump.

6 . The hand tremor treatment device of claim 5 , wherein the pump is configured to inflate and deflate the airbag in response to an airbag signal from the controller.

7 . The hand tremor treatment device of claim 1 , wherein the ventral vibration-inducing device and the dorsal vibration-inducing device are each selected from the group consisting of a rotary vibration motor and a piezoelectric linear vibration motor.

8 . The hand tremor treatment device of claim 1 , wherein the hand tremor treatment device comprises at least one vibration-inducing device configured to produce vibration in a first frequency range and at least one vibration-inducing device configured to produce vibration in a second frequency range.

9 . The hand tremor treatment device of claim 8 , wherein the first frequency range is 0.1 Hz to 1 kHz.

10 . The hand tremor treatment device of claim 8 , wherein the second frequency range is 10 kHz to 2.5 MHz.

11 . The hand tremor treatment device of claim 1 , further comprising an accelerometer, wherein the controller is configured to detect hand tremor onset using the accelerometer.

12 . The hand tremor treatment device of claim 1 , further comprising an angular velocity sensor, wherein the controller is configured to detect hand tremor onset using the angular velocity sensor.

13 . The hand tremor treatment device of claim 1 , wherein the ventral pad further comprises a user input device.

14 . A hand tremor treatment system, comprising
a first hand tremor treatment device, comprising
a first ventral pad configured to be positioned on a ventral surface of a wrist of a subject and including a first ventral compression-inducing device and a first ventral vibration-inducing device;

a first lateral strap connecting the first ventral pad and the first dorsal pad and configured to pass over a lateral surface of a wrist of the subject;
a first medial strap connecting the first ventral pad and the first dorsal pad and configured to pass over a medial surface of a wrist of the subject;
a first wireless communication device; and
a controller, and
a second hand tremor treatment device, comprising
a second ventral pad configured to be positioned on a ventral surface of a wrist of a subject and including a ventral compression-inducing device and a second ventral vibration-inducing device;
a second dorsal pad configured to be positioned on a dorsal surface of a wrist of the subject and including a dorsal compression-inducing device and a second dorsal vibration-inducing device;
