An example method for assisting a patient to conduct a physical therapy session can include: presenting information about the physical therapy session on a display, the information including one or more actions to be performed by the patient； capturing one or more images of the patient as the patient performs the one or more actions； detecting, by a computing device, a safety risk related to one or more medical devices associated with the patient during the physical therapy session； and providing feedback regarding the safety risk. Other methods can include: detecting, by a computing device, using the one or more images, a level of effort from the patient during the physical therapy session； and modifying a future physical therapy session for the patient based upon the level of effort； or allowing the patient to compete with other patients during the physical therapy session based upon the level of effort.
