Fall risk evaluation method, fall risk evaluation device, and non-transitory computer-readable recording medium in which fall risk evaluation program is recorded

This invention describes a method and device to evaluate a person's risk of falling by analyzing their walking. It works by measuring how much their waist moves up and down during specific parts of their stride, particularly the average vertical displacement of the waist during the first 60% of a leg's stance phase. It can also consider knee and ankle joint angles.

Why it matters: Since 2020, advancements in wearable sensor accuracy and AI-driven computer vision for pose estimation have made it significantly easier to acquire and process the detailed walking data required for this analysis using common devices.
