This document describes AXARM, a tele-rehabilitation tool that allows specialized professionals to conduct remote rehabilitation sessions with patients in their homes using broadband internet. It has the following key features: - It addresses issues with geographical dispersion of patients, lack of adapted transportation, and patients' handicaps in the province of Girona. - It uses a hybrid peer-to-peer architecture with secure Jabber communications to allow audio/video sessions between patients' homes and rehabilitation centers. - The application is modular, multi-platform, and customizable to suit different patients' needs and hardware configurations. It aims to offer accessible and continuous remote treatment.
