Simple GRF prediction model

Simple GRF prediction model#

Example of full body MoCap model using the Plug-in-Gait marker protocol but without force plates. The external forces are instead predicted using the GRF algorithms.

Motion capture data is often recorded without force plates. In traditional inverse dynamics, this would make it impossible to perform a dynamic analysis. However, AnyBody has the possibility to predict ground reaction forces (GRF), so you can make inverse dynamics models based on recorded motion without GRF force measurement (Fluit et al., 2014; Jung et al., 2014).

More information is available in the documentation for the GRF prediction.
