Collaborative sensorimotor intelligence: the scrum as a model.

Aim: Using M-Rex, a rugby scrum simulator, we developed tools to describe scrummaging forces and to prevent accident.

Methods: We tested three groups of frontliners at national level. The simulator was passive or responded to the player(s) to simulate the reaction of opposite players.

Inconsistent anticipatory postural adjustments (APAs) in rugby players: a source of injuries?

Background: We are developing since 2010 with Thales and the (FFR) M-Rex, a new kind of rugby scrum simulator. The study questioned whether it could improve safety and protect players from injury by using it as a tool for training/coaching the packs.

Aim: To explore the anticipatory postural adjustments (APAs) during the engagement of the ruck, because these predictive neck and back muscles contractions protect the spinal cord at the time of impacts, which is crucial to prevent injuries.

Impact of the national prevention policy and scrum law changes on the incidence of rugby-related catastrophic cervical spine injuries in French Rugby Union.

Background And Aims: Catastrophic cervical spine injuries are rare in rugby union but require close monitoring. The aim of this study was to analyse the incidence of severe cervical spine injuries and determine the impact of a national prevention programme and new scrum rules implemented by the French Rugby Union.

Methods: A prospective study was performed between 2006 and 2013 including all players affiliated to the French Rugby Union.
