2. Introduction
Home • Patient monitorization and follow up. Patient education
telemedicine • Home excercise
• Communication means with health care professionals
Systems
Drawbacks • Loss of motivation
• High rates of abandonment; patients give up
• Motivate patients to continue their physical rehabilitation
programs through:
Our objective • Socializing
• Serious Games
• Education and an atractive environment
