Wearable inertial measurement unit systems

Wearable inertial measurement unit systems are associated with real-world fall-detection performance in humans (Laboratory accuracy often >95%; real-world sensitivity 55%–80%).

“laboratory-simulated-fall accuracy figures (often >95%) do not transfer to real-world, unscripted settings, where sensitivity for actual falls in older cohorts has been reported as low as 55%—80%”
