FUNDAMENTALS OF 3D KINEMATIC ANALYSIS

This webpage is intended to provide the biomechanics student with a graded introduction to three dimensional rigid body kinematics.

A review of linear algebra is first presented with simple examples relating a physical process to the corresponding mathematics.

A calibration procedure is described which identifies the global coordinates of an anatomical landmark. The axes of two rigid bodies are used to define a joint coordinate system for description of relative segment rotation.

Finally, sample data files are available to the user who can develop an understanding of the calculations and interpret the movement being studied.

The terminology and nomenclature recommended by the International Society of Biomechanics are used throughout this website.

You may go directly to a specific topic, or follow the tutorial progressively.
