Although physical exercise is recommended to maintain health and to counteract the deleterious effects of chronic diseases, home exercising is rarely performed autonomously by patients. Hence, there is urgency to introduce and validate rehabilitation protocols based on a combination of technological solutions and specific health requirements in order to guarantee continuity and quality of care to patients with chronic diseases [1]. The aim of this presentation is to describe the development and initial implementation of an integrated platform of telerehabilitation, based on information and communication technologies. The platform is the product of a Lombardy Region grant (Regione Lombardia, Programma Operativo Regionale 2014-2020, “Bando Call HUB Ricerca e Innovazione”) to Istituti Clinici Scientifici Maugeri IRCCS. Preliminary results have been obtained in five healthy subjects testing the feasibility of the integrated platform in a lab setting (Fig. 1). The platform includes an @home fully-integrated kit composed of: 1) wearable inertial devices, 2) digitally-controlled resistance band, 3) time-of-flight range camera 4) mini-PC with exergames. The @home kit is connected with: 4) cloud-based software systems for programming and monitoring exercises, 5) intelligent conversational agents (chatbot) and virtual coach on personal smartphones. The exergames are based on Otago- inspired exercises [2], including strength, balance, aerobic and cognition. The hardware of the exergames consist of a mini-PC, to be connected to a home TV set, eight inertial measurement units (IMUs, two for proximal and distal part of each limb), providing both accelerometer and gyroscope assessments, a 3D motion range camera, and an extensible band with programmable resistance, exerted by an electric motor. This arrangement allows to detect and record the movement patterns of the subjects. A Digital Support System (DSS) in cloud allows the remote definition and supervision of exercising programs on a deferred basis, thus reducing operator time. An assisted interaction with subjects is allowed through a chatbot and a smartphone app allowing not only to monitor completed activities and achieved progresses but also to receive reminders and advice for the upcoming planning activities. The game interface and an avatar of the subject, detected by a range camera, are shown on a TV screen. Operating together, IMUs and the range camera can not only track the movement, but also assess it (as speed and joint range of motion). The DSS operates in an asynchronous mode allowing the continuous remote supervision of the rehabilitation activities, with the possibility to modify the rehabilitation program and progressively adapting it to subject’s performance. The chatbot and the smartphone app allow continuous and assiduous first level contact with the subject. The prototype of the platform is innovative as it is based on algorithms both for evaluations and classification of the results data on a deferred basis at variance with the existing telerehabilitation devices. The platform provides also rehabilitation assistance and advice, likely reducing the need of repeated consultations with the physiotherapist. Finally, this intervention technology might take part in the creation of a standardized evaluation and rehabilitation prescription system, leading to better quality of healthcare assistance.
