Recreating Fall Risk Appraisal (FRA) matrix using R to support fall prevention programs

Objective: This study aimed to optimize Fall Risk Appraisal (FRA) graphing
for use in intervention programs tailored toward reducing the fall risk of
older adults by using computing graphic functions in the R language.
Materials and Methods: We utilized RStudio, a free development environment
for the R language, as well as the functions within the “ggplot2” and
“grid” packages, to develop a code that would recreate the FRA Matrix for
use in data visualization and analysis, as well as feedback for older
adults. Results: The developed code successfully recreates the FRA Matrix
in R and allows researchers and clinicians to graph participant data onto
the matrix itself. Conclusions: The code presented in this study recreates
the FRA Matrix instrument in the R language and gives researchers the
ability to instantaneously add, remove, or change different aspects of the
instrument to improve its readability for researchers and older adults.
