Around 700 rugby players in Dunedin are getting hi-tech mouthguards as part of a world-first study into concussion, funded by World Rugby with assistance from NZ Rugby. The mouthguards - which cost $300 each - collect and wirelessly transmit data about load, location, direction, motion every time there is a collision between players. Over the last few years a lot of research has gone into concussion at the professional level, but not at lower levels. This is one of the first studies to dive into community clubs, and will help develop concussion prevention programmes.
New Zealand Rugby research scientist Danielle Salmon joins the show to discuss the study.
