Impact Monitoring: how it works
The X2 Biosensor is a skin adherent device placed on the occipital bone of a player prior to participation.
The accelerometers in the device measure linear and rotational forces which can be broadcast using low frequency wireless technology to the sideline during play and also be downloaded after a game for further analysis.
The bio senses allows forces to be measured and visually demonstrated using a proprietary injury management software program on a computer.
This data can also be viewed in the integrated concussion assessment for the individual player to assist in the overall diagnosis of concussion.
During the time the biosensor is worn, impact data is recorded in six directions and a timeline of impact can be output for analysis for an individual player.
Absolute thresholds for damage had yet been established for impact forces, so it is impossible to say at this stage that a given force will result in a concussive episode.
Individuals vary greatly in their susceptibility to sustain damage as a result of an impact, and a large number of factors can influence whether or not they ultimately suffer a concussion.
A combination of data integrating impact force and epidemiological studies will help provide an assessment of the probability that concussion is likely to occur in a given individual based on population studies.
The illustrations here are from a rugby union player in a single game.
The blue arrows represent the direction of force up to 40G, the orange arrows from 40 to 70 G and the red arrows reflect forces in excess of 70 G.
These impact forces were measured in a single player in the under 11 age group.
