Falls classification using tri-axial accelerometers during the five-times-sit-to-stand test

Highlights • Accelerometry may enhance the 5-times-sit-to-stand test (FTSS) as falls assessor. • 39 older adults (19 fallers) performed 4 FTSS trials, using accelerometers. • 46 statistically reliable accelerometer-derived FTSS features were identified. • Model developed to classify falls status usi...

Description
Summary:Highlights • Accelerometry may enhance the 5-times-sit-to-stand test (FTSS) as falls assessor. • 39 older adults (19 fallers) performed 4 FTSS trials, using accelerometers. • 46 statistically reliable accelerometer-derived FTSS features were identified. • Model developed to classify falls status using reliable features, 74.4% accuracy. • Superior cross-validated classification with accelerometry compared to FTSS time.
