Balance measured by the sway balance smart-device application does not discriminate between older persons with and without a fall history.

Background: Clinical functional assessments of balance often lack specificity and sensitivity in discriminating and predicting falls among community-dwelling older adults.

Aims: We determined the feasibility of using a smart-device application measuring balance to discriminate fall status among older adults. We also evaluated differences between smart-device balance measurements when secured with or without a harness.
