Article: Inertia properties of body segments from MRI data

PURPOSE One of the variables in the equations of human motion is the moment of inertia of body segments. In addition to the moment of inertia, volume and center of gravity of segments must be determined. Collectively these are known as inertia properties.

Traditionally, investigators have estimated inertia properties from regression equations based on experimental data collected from a sample of elderly Caucasian male cadavers. There are many body types: females, children, members of other races, and the disabled, whose inertia properties are not well represented by these regression formulae.

The purpose of this project is to use data from magnetic resonance imaging (MRI) to determine the ...
