• Present background material on measuring and estimating body segment parameters
• Outline computational methods for quantifying total body and segmental inertial characteristics for planar (2D) and spatial (3D) motion analyses

Carefully read up to Three-Dimensional (Spacial) Computational Methods

METHODS FOR MEASURING AND ESTIMATING BODY SEGMENT PARAMETERS

• Cadaver studies
• Mathematical modeling
• Scanning and imaging techniques
• Kinematic studies

Segment mass = mass% (total mass)

Segment center of mass = proximal + length% (distal - proximal)

• x_cm = x_proximal + length% (x_distal - x_proximal)
• y_cm = y_proximal + length% (y_distal - y_proximal)
