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.

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; andproviding 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. 2. The method of claim 1, wherein the prosthetic device comprises a powered prosthetic knee. 3. The method of claim 1, wherein the second sensitivity level is associated with an increase in an ability of the patient to trigger movement for the action in comparison to the first sensitivity level. 4. The method of claim 1, further comprising: collecting movement data from one or more sensors of the prosthetic device, the movement data including position and speed data for the prosthetic device;analyzing the movement data collected by the prosthetic device to determine if the patient is conditioned for a change of power level and sensitivity level of the prosthetic device; andselecting the second power level and the second sensitivity level based on the analysis of the movement data. 5. The method of claim 1, wherein the second power level provides a different amount of muscle assistance, when moving, compared to the first power level. 6. The method of claim 1, wherein the actively actuatable joint assembly comprises an ankle joint assembly. 7. The method of claim 1, wherein the prosthetic device comprises a foot assembly, a lower leg assembly, and an ankle joint assembly connecting the foot assembly and the lower leg assembly. 8. The method of claim 1, wherein the user interface comprises a graphical user interface. 9. The method of claim 1, wherein the user interface comprises a keypad. 10. The method of claim 1 further comprising selecting, after a length of time, the second sensitivity level, wherein the second sensitivity level requires a decreased amount of effort from the patient to trigger movement of the prosthetic device in comparison to the first sensitivity level. 11. The method of claim 1, wherein the action is a first action, and further comprising selecting the second sensitivity level for a second action of the prosthetic device, the second action different than the first action. 12. The method of claim 11, wherein the first sensitivity level is different from and set separately from the second sensitivity level. 13. The method of claim 1, wherein each of the plurality of sensitivity level settings is indicative of a range of measurements of patient movement detected by one or more sensors of the prosthetic device that are required for triggering movement of the prosthetic device. 14. The method of claim 13, wherein the measurements detected by the sensors include at least one of the following: angle, pressure, and acceleration measurements. 15. The method of claim 1, wherein each of the plurality of sensitivity level settings is indicative of a level of patient motion detected by one or more sensors of the prosthetic device that is required for triggering the automatic movement of the prosthetic device. 16. The method of claim 1, wherein the plurality of sensitivity level settings comprises a low sensitivity level setting and a high sensitivity level setting. 17. The method of claim 1, wherein the action comprises at least one of standing, sitting, and walking. 18. The method of claim 1, wherein the action comprises at least one of ascending ramps, descending ramps, ascending stairs, and descending stairs. 19. The method of claim 1, wherein the action is a first action, and further comprising assigning the first power level to the first action and assigning a third power level to a second action, wherein the first power level is different from the third power level and the first action is different from the second action. 20. The method of claim 1, further comprising selecting particular power levels for each of a plurality of actions. 21. A device attachable to a limb of a patient, the device comprising: an actively actuatable joint assembly; anda controller configured to: select, 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,select, 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,provide to the actively actuatable joint assembly 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,select, 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,trigger movement of the actively actuatable joint assembly for the action based at least in part on the second sensitivity level, andprovide to the actively actuatable joint assembly 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. 22.
