Sensors help predict when senior citizens are at risk of a fall

TechCrunch highlights research that aims to help care-givers and medical practitioners anticipate and prevent falls by senior citizens before they happen. 

Using motion-triggered cameras, the researchers measured the gait and stride of the inhabitants of a residential home in the US, and were able to predict falls several weeks in advance, where the walking speed of the older person began to slow and their stride length got shorter.
