ScienceDaily (May 20, 2009) — Whether on the trail, at the gym, or even on the front-porch steps, what happens inside your ankle in the milliseconds following a single misstep could sentence you to a lifetime of ankle trouble.

And it’s not just the ligaments left with lasting damage, finds Brigham Young University researcher Ty Hopkins and collaborators from the University of Michigan. Their new study points to a leg muscle whose speed and quality of protective response is permanently compromised after a sprain.

“The lateral muscles of the leg are key to ankle injury,” said Hopkins, a co-author on the study in the current issue of The American Journal of Sports Medicine. “They are key because they resist the movement that is involved in injury itself and position the foot during movement.”
