FAI: ankle instability. Proprioceptive issues

We have been saying this over and over, sorry for the repeated nature of this concept. But ankle sprains should not be taken lightly. This study showed:
"Conclusions: Individuals with unilateral FAI had increased error ipsilaterally (injured limb) for inversion movement detection (kinesthesia) and evertor force sense and increased error contralaterally (uninjured limb) for evertor force sense."

No only do they have loss of kinesthesia on the injured side, but this presents along with a reduced evertor force sense as well as contralateral processing deficits. The Brain is paying close attention to the first things that hits the ground, and noting how stable/unstable it is.
Ankle sprains cannot be taken lightly, even the mild ones. Plus, do not forget about the corruption of the frontal plane at the hip that often occurs after these events.
