Abstract A method for customising an instrumented mouthguard device for a subject, which is performable on an instrumented mouthguard formed via the following steps: performing a 3D scan of the subject's mouthguard fitting region; based on the 3D scan of the subject's mouthguard fitting region, forming a mouthguard body from resilient plastics material; mounting a plurality of motion sensor components to the formed mouthguard body, and performing additional construction steps thereby to form an instrumented mouthguard; the method including: attaching the instrumented mouthguard to a moving unit which is configured to move the instrumented mouthguard in a predefined manner; capturing data from the one or more motion sensor components during the movement of the mouthguard in the predefined manner; processing the captured data thereby to identify relative orientation and position of the plurality of motion sensing components; performing a 3D scan of subject's head; based on the 3D scan of the subject's head, estimating relative locations of the subject's jaw and brain; based on (A) the estimated relative locations of the subject's jaw and brain; and (B) the relative orientation and position of the plurality of motion sensing components, defining transforms for data received from the motion sensing components which approximate accelerations for a defined point on the user's head.
