RecruitmentCurveFitting 1.2.7

A package for fitting sigmoid and bell-shaped functions to EMG recruitment-curve measurements

This package provides classes Sigmoid and HillCurve for fitting, plotting and interpolating EMG recruitment curves. These might be suitable for the M-wave and H-reflex components, respectively, of the EMG responses to electrical peripheral nerve stimulation. Feed in a sequence of stimulation intensities and corresponding sequence of response magnitudes. These can be used from the command-line, outside of python.

The package also provides a higher-level class RecruitmentCurve which takes in EMG waveforms, together with information on the start and end times of the response components of interest, and performs either or both of the above fits, optionally rendering the results on an interactive plot.

To get started:

python -m pip install RecruitmentCurveFitting
python -m RecruitmentCurveFitting --unpack-examples
python -m RecruitmentCurveFitting example-data1.txt example-data2.txt --plot
python -m RecruitmentCurveFitting --help
python -m RecruitmentCurveFitting --help-module
