About the Conventional Gait Model 2.3
One of the main applications of ProCalc is to build and apply biomechanical models. If this is your primary aim, it is important to know which particular biomechanical model you wish to use, as this will govern the types of calculations defined within ProCalc.
In this tutorial, we have selected the Python Conventional Gait Model (CGM) version 2.3, also known as CGM2.3 or pyCGM2.3. This version of CGM has been developed by Fabien Leboeuf at Salford University, UK.

The marker set for CGM2.3 looks like this (for clarity, only the left side is shown):
The marker set is similar to earlier versions of CGM, but uses medial markers at the knee and ankle to determine the frontal planes of the femur and tibia.
Extra tracking markers are used on the anterior aspect of the thighs and shanks.
