Abstract

Disclosed are adjustable powered rehabilitation devices and methods for using the same to rehabilitate and/or train a user. The rehabilitation devices preferably have a plurality of selectable power settings that correspond to one or more rehabilitation-oriented actions or functions of the rehabilitation devices. For example, the power of the rehabilitation device may be selected based on a need, ability, muscle-power and/or physiological characteristics of the user. For instance, a rehabilitation device may be operated at a relatively low power setting to allow a patient to use his or her own muscle power when moving with the rehabilitation device. The rehabilitation device may also include an adjustable sensitivity level that corresponds to a user difficulty in triggering a particular rehabilitation-oriented action. The powered rehabilitation device may also temporarily be used to train a user in interacting with a passive or more conventional prosthetic device.

Claims

1. A training device for use with a limb of a patient, the training device comprising:

an actively actuatable joint;

an interface module configured to receive a selection of at least one of a plurality of power settings for determining power applied by the actively actuatable joint and a user selection of at least one of a plurality of sensitivity level settings to user motion for triggering automatic movement associated with one or more motions of the actively actuatable joint, wherein respective sensitivity level settings are associated with particular triggering levels of user motion; and

a control module configured to output at least one control signal based at least on the at least one power setting selection and the at least one sensitivity level setting user selection, the at least one control signal being indicative of a power of the actively actuatable joint for at least partially replacing muscle function of the patient during a first category of motion of the training device, wherein the control module is configured to output the at least one control signal based at least on a comparison of a sensed user motion, detected by a sensing module, to the triggering level associated with the at least one sensitivity level setting user selection.

2. The training device of claim 1, wherein the power of the actively actuatable joint corresponds to a propulsion of the actively actuatable joint.

3. The training device of claim 1, wherein the actively actuatable joint is a knee joint.

4. The training device of claim 3, wherein the actively actuatable joint comprises an orthotic joint.

5. The training device of claim 1, wherein the interface module is configured to connect to a network.

6. The training device of claim 1, wherein the control module is further configured to output the at least one control signal based on physiological parameters of the user.

7. The training device of claim 1, wherein the interface module is further configured to receive a selection of one of a plurality of second power settings, wherein the plurality of second power settings corresponds to a second power of the actively actuatable joint during a second category of motion of the training device, the second category of motion being different than the first category of motion.

8. The training device of claim 1, wherein each of the plurality of sensitivity level settings is indicative of a predetermined range of sensed measurements required for triggering the first category of automatic motion of the training device.

9. The training device of claim 8, wherein the sensed measurements comprise at least one of sensed angle, pressure, and acceleration measurements.

10. The training device of claim 1, wherein the plurality of sensitivity level settings comprises at least one of a high, a medium and a low setting.

11. The training device of claim 1, wherein said comparison of a sensed user motion, detected by a sensing module, to the triggering level comprises determining that the sensed user motion attains the triggering level.

12. The training device of claim 1, wherein said comparison of a sensed user motion, detected by a sensing module, to the triggering level comprises determining that the sensed user motion corresponds to a range of triggering measurements associated with the triggering level.

13. A training device having propulsive capabilities, the training device comprising:

an actively actuatable knee joint;

a user interface module configured to receive a user selection of at least one of a plurality of sensitivity level settings to user motion for triggering automatic movement of the actively actuatable joint, wherein respective sensitivity level settings are associated with particular triggering levels of user motion;

and an adjustable-power module configured to output one or more control signals for controlling an amount of power to be applied during a movement of the actively actuatable knee joint, wherein the adjustable-power module is configured to output the one or more control signals based at least on a comparison of a sensed user motion, detected by a sensing module, to the triggering level associated with the at least one sensitivity level setting user selection.

14. The training device of claim 13, wherein the adjustable-power module is further configured to output the one or more control signals based on at least one received physiological characteristic of a user.

15. The training device of claim 13, wherein the plurality of sensitivity level settings comprises a low sensitivity level setting and a high sensitivity level setting.

16. The training device of claim 15, wherein a user selection of the low sensitivity level setting requires a narrower range of at least one of sensed angle, pressure, and acceleration measurements of user motion than a user selection of the high sensitivity level setting to trigger the automatic movement of the actively actuatable knee joint.

17. The training device of claim 13, wherein the automatic movement corresponds to a category of motion selected from the group consisting of ascending stairs, descending stairs, ascending a ramp and descending the ramp.

18. The training device of claim 13, wherein the user interface module comprises a keypad.

19. The training device of claim 13, wherein the user interface module comprises a graphical user interface.
