GRFAngles: Calculate angles of orientation for ground reaction forces

In MorphoFun/kraken: Analyses for bone biomechanics

Calculate angles of orientation for ground reaction forces

Description

Calculates the net ground reaction force (GRF) and angles of the GRF orientation using information about the vertical, mediolaterl, and anteroposterior components of the GRF.

Usage

GRFAngles(myData, ...)

Arguments

myData

A data.frame of four columns of numeric data in the following order: Measure of time (e.g., seconds, percent of stance), vertical component of the GRF, mediolateral component of the GRF, and anteroposterior component of the GRF.

Details

These procedures follow the methodology used in Kawano and Blob (2013) and Kawano et al. 2016.
