Despite the resolution of pathology at admission, many hospitalized patients are discharged in a worse functional state, particularly in terms of walking capabilities, due to hospitalization inactivity. Early interventions to maintain the functional state through exercise such as passive mobilization, executed during hospitalization, have been proven to be effective in preventing physical and cognitive decline. Unfortunately, many patients can be excluded from such treatments due to the high number of people hospitalized and the limited availability of healthcare personnel. This paper presents a framework that allows the patient to autonomously perform the exercises without the assistance of qualified personnel. Such a framework exploits the advantages of an Augmented Reality (AR) device in which the patient can visualize real-time instructions on the exercises and directions on their execution. The monitoring of the patient’s movements during exercise is accomplished by means of dedicated wearable sensors fixed to the patient’s limb. The system was tested in preliminary experiments on healthy people.
