Amputee Gait Analysis using fgdiR

In fgdiR: Functional Gait Deviation Index

knitr::opts_chunk$set(
  collapse = TRUE,
  comment = "#>"
)
require(magrittr)
library(fgdiR)

Overview

The fgdiR package computes the Functional Gait Deviation Index (FGDI) for quantifying gait pathology using multivariate functional principal components.

Example Usage

Load Amputee Data

data(A_Data)
data(A_data_info)

Compute FGDI

ID <- c(rep("Case", 18), rep("Control", 42))
fgdi_out <- FGDI(A_Data, ID, PVE_I = 0.99)

Visualize One Joint Comparison

plot_gait_comparison(1, "Pelvis Tilt", fgdi_out, A_Data, ID, combined=FALSE)
