Rehabilitation using a prosthetic device
First Claim
1. A method comprising:
- providing a prosthetic device that is attachable to a limb of a patient, wherein the prosthetic device comprises an actively actuatable joint assembly;
selecting, based on input received via an user interface for the prosthetic device, a first power level of a plurality of power levels of the prosthetic device for assisting movement of the patient;
selecting, based on input received via the user interface for the prosthetic device, a first sensitivity level for triggering movement of the actively actuatable joint assembly for an action from a plurality of sensitivity levels for triggering movement of the actively actuatable joint assembly for the action, wherein the plurality of sensitivity levels are associated with different triggering levels for patient motion for triggering the movement of the actively actuatable joint assembly for the action;
providing the selected first power level for assisting movement of the patient for the action and triggering movement of the actively actuatable joint assembly based at least in part on the selected first sensitivity level;
selecting, after a length of time, a second sensitivity level for triggering movement of the actively actuatable joint assembly for the action, wherein the second sensitivity level requires a narrower range of at least one of detected angle, pressure, and acceleration measurements of patient motion than the first sensitivity level to trigger movement of the actively actuatable assembly for the action;
triggering movement of the actively actuatable joint assembly for the action based at least in part on the second sensitivity level; and
providing a second power level for assisting movement of the patient for the action, wherein the second power level is different than the first power level.

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.
