Ankle Sprain

We apply the Ottawa Ankle Rules at the first visit to determine this quickly. An X-ray is indicated if you have bone tenderness directly over the posterior edge of either malleolus (the bony bumps on either side of the ankle), or over the base of the fifth metatarsal (the bump on the outside of your foot), or if you cannot bear weight for 4 steps. If none of those criteria are met, the probability of a fracture is very low and imaging isn't necessary. The Rules have a near-100% sensitivity for detecting clinically significant fractures.

Yes — this is the most important point about ankle sprains. Pain resolves well before the ligament, proprioceptive (balance) system, and peroneal muscles have fully recovered. Between 20 and 50% of people who "recover" from ankle sprains go on to develop chronic instability — repeated rolling, a sense of giving way, and long-term vulnerability — because they stopped at pain resolution rather than completing the full rehabilitation sequence. The balance training and strength work done after pain resolves are what dramatically cut re-injury risk.

The talocrural joint (where the ankle bone meets the leg bones) has a specific accessory motion called posterior talar glide that is commonly restricted after an ankle sprain. This restriction limits full dorsiflexion (the ability to bring your foot up) even when pain is gone, and reduced dorsiflexion changes how you land and load the entire lower leg with every step. Restoring this joint motion with specific mobilization technique is one of the most evidence-supported manual therapy interventions for ankle sprain and is often the reason one well-targeted adjustment changes function noticeably.

Functional taping or a lace-up ankle brace during sport is well-supported for reducing re-sprain risk in the first 6 to 12 months after a significant ankle sprain. Research shows bracing reduces recurrence rates by roughly 40 to 50% compared to no support. This doesn't mean permanent reliance — once proprioception and peroneal strength are fully restored, many athletes discontinue external support without increased risk. Think of it as insurance while the neuromuscular system catches up to the healed ligament.

Almost certainly, if you've had more than two significant sprains and still feel your ankle gives way on uneven ground. Chronic ankle instability (CAI) is a well-defined condition resulting from incomplete neuromuscular recovery after sprain — the ligament may have healed, but the mechanoreceptors in the damaged tissue that feed your brain position information are disrupted. Proprioceptive training on unstable surfaces, combined with peroneal strengthening, can substantially restore stability even years after the original injury.
