AIMS AND CONTENT LEARNING OUTCOMES The course covers the technologies, the analytical methods, the modeling approaches used for the analysis and quantification of human movement and its neural correlates. Specific topics include three-dimensional analysis of movements, muscle and body mechanics, physiology and physiological signals in motor control, computational motor control. AIMS AND LEARNING OUTCOMES By the end of the course the students will be able to record and analyse human movements (kinematics, kinetics, muscle activity) and to describe the underlying control, using the appropriate devices and analytical and modeling tools. PREREQUISITES There are no formal prerequisites, but students are expected to know mechanics, geometry, calculus and signal analysis. TEACHING METHODS The course combines lectures, guided experimental sessions, and analysis of movement data. SYLLABUS/CONTENT Part I: movement A. Human movement (wk 1).
