Lessons

• Kinematic Tutorial
• Inverse Dynamics Tutorial
• Muscle Forces Tutorial
• XSENS Tutorial

The examples are based on a walking motions (normal and altered with an ankle brace) published in a conference recorded with optoelectronic system. The second example is a tennis service motion from XSENS Analyze suite based on inertial sensors.

1. Kinematic Tutorial

The first objective of the tutorial is to compare kinematic results from anthropometric calibration and geometrical calibration. At the end of the tutorial, key concepts should be understood: rotation sequences, inverse kinematics, reconstruction error, convergence of geometrical calibration.

The second objective of the tutorial is to compare the kinematic of normal walking gait with altered gait.

2. Inverse Dynamics

The objective of the second lesson is to compare the torques of normal walking gait with altered gait. At the end of the tutorial, key concepts should be understood: inverse dynamics, newton-euler algorithm, torques

3. Muscle forces

The objective of the second lesson is to compare the muscle forces of normal walking gait with altered gait. At the end of the tutorial, key concepts should be understood: cost functions, muscle mechanics

4. XSENS Tutorial

The objective of the last tutorial is to evaluate ground reaction forces of a tennis service motion recorded with XSENS inertial sensors using the force prediction algorithm. At the end of the tutorial, key concepts should be understood: contact points, contribution to dynamic equilibrium.
