E-edition: #RugbyMedicine

Dear Reader, Welcome to this special BJSM e-Edition on #RugbyMedicine. The sport of rugby union has come a long way in its quest to enhance player welfare and safety, and we hope this e-Edition provides an insight into the sport’s journey, as well as some of its more modern initiatives and advances. The e-Edition has been split into two main sections that correspond to areas within the field that have seen major advances, with then a sprinkling of other #RugbyMedicine gold-dust on top. We are hugely grateful to many people for collaborating on this project, especially those who have helped contribute new & exciting material. A huge thanks goes to Drs Martin Raftery, Eanna Falvey & Ross Tucker, Dominic Rumbles and Sir Bill Beaumont for their help in determining the scope & content, as well as Drs Simon Kemp & Keith Stokes for their support of the project. A huge thanks also to the likes of (soon to be Dr) Gautam Menon, Ania Tarazi and Jimmy Walsh for creating some of the brilliant animations/podcasts that feature so heavily. Your feedback is most welcome, please do get in touch with us via the usual social media channels if you have any queries, but in the meantime, we hope you enjoy this resource (as well as #RWC2019!) Sincerely, Dr Steffan Griffin | @SteffanGriffin BJSM Senior Associate Editor & Editorial Fellow (on behalf of the BJSM Editorial team)

As Chief Medical Officer for World Rugby I would like to welcome everyone to this rugby medicine, e-edition of the British Journal of Sports Medicine. This e-edition has been produced to coincide with our Rugby World Cup that is being held in Japan from September 19 to November 2 in 2019. Our Rugby World Cup, played every four years, is our game’s most elite competition bringing together the 20 top nations from around the world. Player welfare, as you will hear from Sir Bill Beaumont, Chairman of World Rugby, is the sport’s number 1 priority. Contributions to this e-edition come not only from World Rugby but also recognise research and welfare programs developed and introduced by some of our larger national Unions.

I would like to thank the BJSM for coordinating this new and exciting method of scientific journalism and in particular would like to recognise the enthusiasm and tireless efforts of Dr Steffan Griffin who initiated and coordinated this exciting project. Dr Martin Raftery Chief Medical Officer, World Rugby

The game of rugby has evolved significantly over the last few decades, and it only take a quick search of historical matches on YouTube to see this first-hand. As mentioned in the podcast, a lot of these laws have been informed by collaborative research studies from around the globe. Below are some seminal papers that informed these initiatives, and an animation of the study that led to some of the recent law changes. Risk factors for head injury events in professional rugby union: a video analysis of 464 head injury events to inform proposed injury prevention strategies Ross Tucker, Martin Raftery et al. Tackling concussion in professional rugby union: a case–control study of tackle-based risk factors and recommendations for primary prevention Matthew J Cross, Ross Tucker et al.

We have seen a huge paradigm shift in the way people view concussions over the last few years, but how have things evolved at a practical level? In this video, we hear from Associate Professor Jon Patricios about his experiences of working pitchside in rugby, and what the current state of play is.

Dr Martin Raftery and Dr Ross Tucker join the BJSM to discuss World Rugby’s injury prevention journey, and most recent player welfare initiatives. We also hear from World Rugby chairman Sir Bill Beaumont on how rugby has evolved in this regard.

One of the intervention we will see rolled out this year is the Load Passport, so what exactly does this look like?

We hear a lot about load these days, but what exactly does this encompass, and how should we go about collecting this data? This podcast with Dr Stephen West PhD delves into the pitfalls of current data collection methods, and provides some golden practical tips about how to best collect load data. Below are some accompanying papers too.

You’ve heard of the FIFA11+ and a few other injury prevention programmes of the same ilk, but what about Activate? Activate relates to the evidence-based injury prevention programme in rugby, designed & implemented by the long-standing collaboration between the University of Bath, and the Rugby Football Union, and now adopted by World Rugby. Below you will find not only the original research papers, but some additional resources that provide some additional insight into the project.
