An open source implementation of the Conventional Gait Model in Python

摘要

The Conventional Gait Model CGM [1,2] has been a standard in clinical gait analysis since the 1990s. Well-known by its commercialisation as Plug-in Gait (PiG, Vicon, Oxford, UK), it is simple and widely understood facilitating discussion between biomechanists and clinicians. Most commercial manufacturers now provide some version of the model. Despite its common use there has been little development of the model since the 1990s perhaps because open source versions have not been available. None of these replicates fully the range of options that are used by different users. The first aim of this paper is thus to present an open source version of the CGM which fully replicates those options.
