To assess the effect of injury to the ankle on postural sway in participants with a history of no injuries, one injury and two or more injuries. To compare the changes in passive range of motion of the ankle in participants with no injuries, one injury and two or more injuries. The results suggest that there are some changes in inversion range of motion and some deficits in proprioception once an ankle injury has occurred. This minor thesis was written by a post-graduate student as part of the requirements of the Master of Health Science (Osteopathy) program.
