30612 - Laboratory of Biomechanics

Learning outcomes

After completing this course, the student will be able to design and perform experiments in the field of biomechanics as well as to interpret the results through the use of statistical and mathematical models. In particular he is able to: - use biomechanical equipments in the laboratory of Biomedical Engineering - design experiments based on gained knowledge - perform experiments with the assistance of the teacher - prepare data for the identification and validation of mathematical models of physical systems - to characterize the biomechanical behavior of biological tissues - study kinematics of the human body using stereo-photogrammetry - study the dynamics of the human body through the use of force platforms - use inertial devices with low invasiveness for the study of movement kinematics and dynamics.
