Primary Outcome Measures

Name	Time	Method
Composite primary outcome - Oculomotor: saccades, anti-saccades, fixations, smooth pursuits, pupillary dynamics, optokinetic reflex, multisensory integration and egocentric localisation using the Tobii eye tracker - a computerised measure of eye movements. All oculomotor outcomes are recorded by the Tobii eye tracker in XML document format.[immediately before and immediately after the intervention]

Secondary Outcome Measures

Name	Time	Method
Cervical spine flexion-relaxation ratio - measured using surface electromyography of the muscles of the posterior cervical spine. Two electrodes are placed in the lower and upper cervical spine and the participant is asked the flex their head forward fully then return their head to a neutral position. Surface electromyography recordings are taken of muscle activity in this procedure and stored electronically. The recordings will be taken by the research assistant.[Directly pre intervention only]
