Teaching methods

During the lectures the general issues related to the design and development of systems for the sensory-motor rehabilitation will be discussed. The course includes laboratory practicals and visits to medical centers. Numerical analysis will help designing and simulating experiments in a realistic way. These will be later performed in the laboratory of Biomedical Engineering. Short theses will allow groups of students to investigate aspects of the course through the analysis of clinical cases.

Assessment methods

The assessment will take place: 

1) in the classroom during exercise solving;

2) in the laboratory during practicals;

3) short theses (optional); 

4) final examination, written and oral.

Teaching tools
