The Quell is a device from Boston, Massachusetts-based Neuromatrix that claims to have brought relief for chronic pain to 81% of their users. The device involves the main unit bing put into a belt that has space for electrical contacts. These are used with a gel-based pad on the other side and wrapped around one's leg to deliver mild electrical pulses that trigger release of natural pain blockers from the brain. It costs US$249 and is currently on sale only in Canada and the US. The device also includes an optional app for advanced sleep tracking functions.
