Firefly | Sports Recovery device for DOMS


Firefly in the USA

The firefly™ device receives FDA 510(k) clearance to market in the USA for faster muscle recovery and improved muscle performance after intense exercise. 

Today we announce the recent FDA clearance for USA commercialization of our sports recovery device, firefly™, indicated for increased lower limb blood circulation to decrease muscle soreness after intense exercise and improve muscle performance.

The size of a wrist-watch and worn at the knee, the battery powered firefly™ device delivers painless electrical impulses to the common peroneal nerve to activate the muscle pumps of the lower leg that return blood towards the heart. The mechanism of action emulates the blood flow rate normally achieved by walking - up to 60% - without having to move or exert energy. An alternative or supplement to active recovery, such as light jogging or swimming, the firefly™ device increases blood circulation without re-imposing cardiovascular strain. 

A clinically proven medical device, firefly™ is used by elite athletes and professional teams in the UK, Canada, Australia and New Zealand. Sarah Thomas, former GB International hockey player and winner of an Olympic bronze medal in the London 2012 Games, and now Director of International Sport at Firstkind, said: “Having experienced the benefits of using firefly™ as part of my recovery protocol in the build up to and during the London 2012 Games, and introducing the device to other elite athletes and professional sports teams in the UK since joining Firstkind, I am now looking forward to building a strong network in elite sport across the USA”. Sarah adds, "incorporating this innovative device into recovery strategies in order to help an athlete recover back to baseline quicker can be a key determinant for success.”

Since receiving FDA clearance we are in discussion with professional teams in North America and will be making further announcements soon. To find out more and register your interest visit our new US website
