Abstract

The purpose of this study was to determine the validity and reliability of a custom-built fall risk smartphone application (Steady™) compared to validated fall risk tests in older adults in a real-world setting. Fifteen participants completed Steady™, which includes entering demographics, rating perceived balance, and completing 5 balance tasks. Following completion, Steady™ computes a single, overall fall risk score. Participants then completed standard, clinical tests assessing their mobility and overall fall risk. Ten participants repeated testing procedures within one week. Spearman's correlations and Interclass Coefficients (ICC) were performed between Steady™ scores and clinical tests. There were moderate and significant correlations between Steady™ scores and the mobility tasks (p's = 0.009 - < 0.001). There was a good and significant ICC for Steady™ scores between testing sessions (ICC = 0.90; p = 0.001). Steady™ may offer a valid and reliable solution to provide self-administered fall risk screening for older adults in home settings.
