EMG signal processing pipeline

EMG Signal Processing Pipeline

pyemgpipeline is an electromyography (EMG) signal processing pipeline package.

This package implements internationally accepted EMG processing conventions and provides a high-level interface for ensuring user adherence to those conventions, in terms of (1) processing parameter values, (2) processing steps, and (3) processing step order.

The processing steps included in the package are DC offset removal, bandpass filtering, full wave rectification, linear envelope, end frame cutting, amplitude normalization, and segmentation.

Scope

This package defines the processing pipeline for both surface EMG and intramuscular EMG but not for high density EMG. The EMG recording requires that the minimum sample rate be at least twice the highest cutoff frequency of the bandpass filter based on the Nyquist theorem.

Overview

In pyemgpipeline, class DataProcessingManager in module wrappers is designed as the main wrapper for high-level, guided processing, and users are encouraged to use it to adhere to accepted EMG processing conventions. The other classes, methods, and functions are considered as lower level processing options.

The package is organized in modules processors, wrappers, and plots.

Module processors includes the base class BaseProcessor of all signal processors and seven classes for different processing steps: DCOffsetRemover, BandpassFilter, FullWaveRectifier, LinearEnvelope, EndFrameCutter, AmplitudeNormalizer, and Segmenter.

Module wrappers includes three wrapper classes to facilitate the signal processing by integrating data and individual processors. Class EMGMeasurement works for data of a single trial, class EMGMeasurementCollection works for data of multiple trials, and class DataProcessingManager is the high-level, guided processing wrapper with EMG processing conventions.

Module plots includes the function plot_emg to plot EMG signals on matplotlib figures and the class EMGPlotParams to manage the plot-related parameters.
