Ankle sprain are frequently encountered of the injuries that arise during rugby union.
To examine the association of potential risk factors obtained from a preseason medical screening with subsequent ankle sprain in collegiate rugby union players. The prospective cohort study examined the association of ankle sprain with possible contributing factors recognized in a preseason medical screening. The study involved 78 elite rugby union players from one university rugby club. Basic demographics, history of injury and current physical findings were assessed and ankle sprain sustained during four playing seasons were recorded. Risk factors for ankle sprain were determined suing a logistic regression model
with significance level set at p = 0.05. Eleven players sustained injuries to the ankle sprain the two seasons. Ankle dorsiflexion range of motion (OR, 0.50; 95%CI, 0.30 - 0.82, p = 0.00) was associated with the ankle sprain. Ankle dorsiflexion range of motion is important risk factors among collegiate rugby union players.
