gait-profile-score 1.0.2

Calculates Gait Profile Score

Welcome to Gait Profile Score Calculator’s documentation!

gpscalc is a package that can be used to calculate the gait profile score as stated in Baker et al. 2009. The package requires the gait trials kinematic data to be stored in a json file using specific variable names. (Baker, R. et al., 2009. The Gait Profile Score and Movement Analysis Profile. Gait and Posture, 30(1), pp. 265-269.) Kinematic gait data has to be in a specific format for the calculation, the specifics of the format required can be seen using the functions below to create example JSON files.

How to use the GPS Calculator

Package Installation

::

pip install gait-profile-score

Create example data in correct format

::

from gpscalculator import exampleInputData

exampleData = exampleInputData()

# Kinematic variable labels required
labels = exampleData.kinematicVariables()
print(labels)

# Example of a kinematic dataset
dataset = exampleData.kinematics()
print(dataset)

# Save an example of the kinematics JSON file required
exampleData.kinematicsJSON("chosen/directory")

Processing the reference group data

::

from gpscalculator import referenceGroup

# List of paths to the reference group kinematics JSON files
referencePaths = [...]

referenceData = refernceGroup()
referenceData.processGroupData(referencePaths)

# The average of the reference kinematic variables over the gait cycle
referenceKinematics = referenceData.avgKinematics

# The average GPS scores of the reference group relative to the average kinematics
referenceGPS = referenceData.avgRefGPS

Calculation of GPS for a single subject

::

from gpscalculator import calculateGPS

# The kinematic data for the selected subject
subjectKinematics = {kinematic data}

# GPS scores for the subject relative to the reference group average kinematics
subjectGPS = calculateGPS(referenceKinematics, subjectKinematics).gps

Plotting the GPS diagram

::

from gpscalculator import plotGPS

plot = plotGPS(referenceGPS, subjectGPS, saveplot="test_gps_plot.png")

Processessing the GPS scores for a subject group

::

from gpscalculator import batchGPS

# List of paths to the subject group kinematics JSON files
subjectPaths = [...]

subjectGroup = batchGPS()
subjectGroup.loadReferenceGroup(referencePaths)
subjectGroup.processSubjectGroup(subjectPaths)

# Print the dataframe containing the subject group GPS data
print(subjectGroup.batchData)
