Code to accompany the manuscript on continuous relative phase analysis of gait over irregular surfaces

Continuous relative phase analysis for gait on irregular surfaces

This repository contains code associated with the following manuscript:

P. Ippersiel, S.M. Robbins, P.C. Dixon. Lower-limb coordination and variability during gait: The effects of age and walking surface, Gait & Posture, 85, 2021, 251-257. https://doi.org/10.1016/j.gaitpost.2021.02.009.

Requirements

Code must be run in Matlab (The Mathworks, Inc. Natick, USA). All tests performed in Matlab 2020a under Mac OS 10.15.5.

Steps (How to run)

1. Dowload or clone the repository to your local computer
2. Open Matlab and use the set path tool to add the root folder Code and all subdirectories to the working path (Set Path --> Add with Subfolders)
3. type crp_irregular_surfaces_process.m in the command line

What happens

The function crp_irregular_surfaces_process.m will :

1. Copy the raw data in the folder Data\raw to Data\processed
2. Compute continuous relative phase metrics (MARP and DP) as described in the paper
3. Extract metrics to a spreadsheet located in Statistics\eventval.xls
