Modeling with CGM2
- Gisela Roberts
- Ben Stanley
The Conventional Gait Model 2 (CGM2) was developed by Dr Fabien Leboeuf (University of Salford), and partly funded by Vicon. It is an open-sourced biomechanical model originally developed in Python 2, and now developed in Python 3. The design of the CGM2 model enhances the Conventional Gait Model whilst maintaining its strengths.
You can use Conventional Gait Model 2 (CGM2) VSTs and biomechanical models from within Nexus so that you can execute CGM2 models on your data.

pyCGM2 is compatible with versions of Nexus from 2.7 and later. It fits straight into Nexus pipelines with the usual gait plug-ins such as the Woltring Filter, Gait Cycle event detection, and Plug-in Gait.
- Nexus 2.9 and later: CGM2 is automatically installed and you can use it without any further setup or installation.
- Nexus 2.7 or 2.8: Download the CGM2 installer and its documentation from:
https://www.vicon.com/downloads/models-and-scripts/cgm2
The following topics contain information about setting up and using CGM2 with Nexus:

Note that if you want to use CGM2 with Python 3, you must use pyCGM2 with Nexus 2.12 or later (see https://pycgm2.netlify.app/code/python-setup/).
