calc_activation_transformations: Calculate nonlinear transformations of activations signals

In ime-luebeck/semgsim: Simulating surface electromyographic (sEMG) and force signals

Calculate nonlinear transformations of activations signals

Description

Calculate a nonlinear input transformation for each muscle that makes the muscle generated the desired relative output force.

Usage

calc_activation_transformations(MUs, MUs_rate_functions)

Arguments

MUs	A data.frame of MUs belonging to (potentially) multiple muscles.
MUs_rate_functions	A data frame containing a column $rate.function that gives the firing rate as a function of muscle activation for each MU.

Details

Depending on the firing rate, MU pool, and twitch force model, a nonlinear transformation of the muscle activation input is calculated, such that the generated relative output muscle force matches the input activation signal in the mean over time.

Value

A list of functions that gives the muscle input as a function of the desired relative output force for each muscle.
