Digitizing the coordinates<br />

of each joint centre in<br />

Referencing anatomical<br />

landmarks to a<br />

anthropometric<br />

biomechanical model<br />

We obtain the position of<br />

each model part (segment)<br />

and of the total CM<br />

It is possible to differentiate velocities and<br />

accelerations, and to estimate forces<br />
