Abstract

A method of prompting a patient includes informing a patient a relationship between a result of an activity being performed by the patient and a first target result to be achieved by the activity. A method of prompting a patient includes informing a patient a relationship between a time and a target result to be achieved by an activity. A method of prompting a patient includes informing a patient a relationship between a position of a portion of the patient and a first target position for the portion.
