Description
Wenqi Ran and co-authors study ankle muscle timing in people with weak ankles in a 2026 paper. Some people sprain the same ankle again and again, a state called chronic ankle instability. Side ankle muscles should fire early to guard the joint when the foot tips inward. The team tested whether that early firing is enough to stop a sudden tip.
Forty walkers stepped on a trapdoor that tipped the foot without warning. Those with weak ankles fired the side muscles more before the tip than the control group. Yet their ankles still rolled inward more after the tip, and one muscle fired less later. The early guard thus seems too weak to hold the joint steady.
