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.
