Recent decades brought technological advances able to improve the life quality of people with disabilities. However, benefits in the rehabilitation of motor disabled people are still scarce. Therapeutic processes are lengthy and demanding to therapists and patients. Our goal is to assist therapists in rehabilitation procedures providing a tool for accurate monitoring and evolution analysis enriched with their own knowledge. We analysed therapy sessions with tetraplegics to better understand the rehabilitation process and highlight the major requirements for a technology-enhanced tool. Results suggest that virtual movement analysis and comparison increases the awareness of a patient’s condition and progress during therapy.
