Reduced postural stability is a major contributor to poor balance increasing risk of fall especially among older adults. Monitoring of postural stability on a regular basis may lead to early detection of declining balance and providing an opportunity for timely intervention. Ultra-Wide Band Impulse Radar (UWB-IR) technology has been proposed for security, rescue and vital sign monitoring. The advantage of UWB radar is that it is non-invasive and can be applied for home monitoring. This paper presents the application of UWB radar to measure spontaneous body sway during quiet standing. Three frequency domain based measurement parameters for spontaneous sway are presented. A trial was conducted using four volunteers to demonstrate the ability of the UWB radar to detect body sway.
