Abstract—Falls among the elderly population are a major cause of morbidity and injury—particularly among the over 65 years age group . Validated clinical tests and associated models , built upon assessment of functional ability , have been devised to estimate an individual ' s risk of falling in the near future . Those identified as at - risk of falling may be targeted for interventative treatment . The migration of these clinical models estimating falls risk to a sur - rogate technique , for use in the unsupervised environment , might broaden the reach of falls - risk screening beyond the clinical arena . This study details an approach that characterizes the movements of 68 elderly subjects performing a directed routine of unsupervised physical tasks . The movement characterization is achieved through the use of a triaxial accelerometer . A number of fall - related fea - tures , extracted from the accelerometry signals , combined with a linear least squares model , maps to a clinically validated measure of falls risk with a correlation of ρ = 0 . 81 (p < 0 . 001) .
