Description
Daisuke Sudo and four colleagues published a 2025 study on predicting falls in older adults with a smartphone. Older adults who have fallen before tend to step with more variable timing than those who have not. The team asked whether that variability, measured while seated, can flag future fallers.
Fifty-eight older adults in eleven senior housing facilities, all taking part in online exercise programs, performed seated stepping exercises at the start. A smartphone measured the coefficient of variation of their step timing, which expresses how irregular the rhythm is. Falls were then tracked for one year. Those who fell had somewhat higher variability at baseline. A phone-based test could make fall-risk screening cheap and repeatable.
