Abstract

A wearable rehabilitation device features a wearable support sized and shaped for worn fitting thereof over a body part of a patient, one or more vibratory stimulators on the wearable support that are positioned and operable to stimulate muscle tendon tissue of said body part of the patient, and one or more accelerometers on the wearable support configured to generate output signals responsive to vibration of said one or more vibratory stimulators. A controller compares output signals from the accelerometer against a targeted vibrational frequency, and adjusts operating conditions of the stimulator based on detected disagreement to achieve the targeted frequency for optimal therapeutic effect.

First claim

1 . A wearable rehabilitation device comprising:
a wearable support sized and shaped for worn fitting thereof over a body part of a patient; and supported on said wearable support:
one or more vibratory stimulators operable to stimulate muscle tendon tissue of said body part of the patient; and
one or more accelerometers configured to generate output signals responsive to vibration of said one or more vibratory stimulators.

2 . The device of claim 1 wherein said one or more vibratory stimulators comprises two vibratory stimulators positioned to respectively overlie two different muscle tendons of said body part.

3 . The device of claim 2 wherein said one or more accelerometers comprises two accelerometers, each of which is configured to generate a respective output signal responsive to vibration of a respective one of said two vibratory stimulators.

4 . The device of claim 2 wherein said two vibratory stimulators are positioned on said wearable support at positions selected to respectively overlie flexor and extensor muscle tendons of said body part.

5 . The device of claim 1 comprising a controller that is configured to receive user input signifying a targeted vibrational frequency of said one or more vibratory stimulators, to receive said output signals from the one or more accelerometers and derive therefrom a measured vibrational frequency of said one or more vibratory stimulators, and is configured to compare said measured vibrational frequency against said targeted vibrational frequency.

6 . The device of claim 5 wherein said controller is configured to control operation of said vibrational stimulators, and to vary one or more operating conditions thereof based on detected disagreement between said measured vibrational frequency and said user input.

7 . The device of claim 5 wherein said controller is configured to vary an operating voltage applied to said vibrational stimulators based on said detected disagreement.

8 . The device of claim 6 wherein said controller is configured to output a confirmation signal upon detected agreement between said measured vibrational frequency and said user input.

9 . A wearable rehabilitation device comprising:
a wearable support sized and shaped for worn fitting thereof over a body part of a patient; and supported on said wearable support:
a first vibratory stimulator positioned on said wearable support at a first location thereon that is arranged to overlie a first muscle tendon of said body part of the patient when said wearable support is donned in a worn position thereon; and
a first vibratory stimulator positioned on said wearable support at a second location thereon that is arranged to overlie a second muscle tendon of said body part of the patient when said wearable support is donned in the worn position thereon.

10 . The device of claim 9 wherein said first and second vibratory stimulators are positioned on said wearable support body at positions selected to respectively overlie flexor and tensor muscle tendons of said body part.

11 . The device of claim 1 wherein said wearable support comprises a wristband.

12 . The device of claim 1 wherein each vibratory stimulator is relocatable among different positions on said wearable support.

13 . The device of claim 1 wherein said wearable support is adjustable in size.
