Prosthetic and orthotic systems usable for rehabilitation

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.
