Comparison of a Non-linear Analysis of Balance During the mBESS to the Sway Balance Application

In order to determine equivalency of the Avert Sample Entropy algorithm's ability to be sensitive to different balance conditions, participants will complete the modified balance error scoring system (mBESS) while standing on a portable force platform. Human-rated errors during the mBESS conditions will be recorded, in addition to measuring balance using the Sway app. These will be compared for levels of agreement and direction of bias using Bland-Altman analyses.
