Functional performance deficits associated with ligamentous instability at the ankle

Objectives To examine whether ankle anterior drawer ligament laxity is associated with deficits in performance testing among otherwise healthy sportspeople. Design Cross-sectional cohort study. Methods Eighty-six volunteers from among sports participants at a military academy consented to the use of their pre-participation musculoskeletal screening information for the lower limb, and to an additional test of ankle proprioception. The lower limb screening included tests of ankle ligament laxity, dorsiflexion range of movement, single leg hop-for-distance, hexagon agility hopping test, and hop-and-hold landing stability test.
