Abstract

This study tested the feasibility of a method to synchronize and evaluate eye, head, and trunk movement patterns during target tracking tasks performed by 10 subjects. A projected central target was randomly repositioned at 40° and 70° of rotation to the left and right. Subjects were instructed to change gaze as quickly as possible. Head and trunk motion was measured using a motion analysis system, and eye-movement was measured using an eye-tracker; all data were synchronized. For healthy subjects, the eye moved faster than the head, there was no trunk movement, and the head moved more than the eye to reach further displaced targets. The method tested was feasible and it could be used to evaluate eye, head, and trunk movement patterns of subjects with injuries such as whiplash and concussions. (131 words) Practitioner Summary Studies of eye, head and trunk movement using synchronized methods are needed. We tested the feasibility of a method to synchronize and evaluate eye, head, and trunk movement patterns. The method tested was feasible and it could be used to evaluate movement patterns of subjects with injuries such as whiplash.
