Gait120 EMG and Kinematic Data Processing Code

This repository contains MATLAB scripts developed for processing and visualizing electromyography (EMG) signals and kinematic data from the Gait120 Dataset. The scripts facilitate EMG data preprocessing, maximum voluntary contraction (MVC) calculations, and kinematic visualization.

Included Files and Descriptions

1. calculateMVC.m

Calculates maximum voluntary contraction (MVC) values from processed EMG signals across multiple tasks and trials.

2. dataVisualizer.m

Visualizes joint angle and EMG signal data from the Gait120 dataset.

Utilizes kinematicsVisualizer and EMGSignalVisualizer functions for visualization.

Includes the function varycolor originally created by Daniel Helmick (2008), provided under a BSD-style license (see function definition within the file for details).

3. emgProcessedDataConstruction.m

Processes raw EMG signals, performing filtering, rectification, MVC normalization, and interpolation.

Generates processed EMG data suitable for further analysis.

4. signalProcess.m

Applies bandpass filtering, rectification, outlier removal, and RMS envelope extraction to raw EMG signals.
