6. Fuglevand Model (Rate Coding and Motor Unit Recruitment Model)

For force and sEMG simulation, we introduce the motor unit recruitment and rate coding (Fuglevand) model in this chapter. This model has already been utilized in numerous research to replicate the force-sEMG relationship in patients suffering from neuromuscular weakness. Their research aims to identify the variables that significantly alter the force-sEMG curve’s slope. To investigate such changes, the Fuglevand model offers flexibility in manipulating different elements. However, building this model is a difficult undertaking. As a result, we offer a comprehensive tutorial on building this model with the R programming language in this chapter. We also provide an R platform open-source code for the Fuglevand model. With the help of this code, force-sEMG connections in both healthy people and the affected population can be studied.
