Athletes are used to pushing limits. Yet, from our work at ProSport Physiotherapy under the guidance of Dave O’Sullivan, who has treated elite rugby, football, and Olympic athletes, the same pattern keeps emerging: an ankle is sprained, a “standard” rehab is completed, the athlete feels fine, and then weeks or months later, the injury returns. Chronic ankle instability is far more common than most realize, and our experience shows it almost never happens by accident.
Load Mismanagement: The Hidden Culprit
Even when pain and swelling settle, the ankle is not automatically ready for high-speed cutting, landing, or sprinting. Many athletes return to training too soon, or load the joint unevenly to protect it subconsciously. The tissue may feel fine under light stress, but real sport demands reveal deficits. Each premature session compounds the problem, gradually reinforcing instability.
Poor Lateral Stability and Foot Pressure Patterns
True ankle strength depends on both the supporting muscles and how the foot distributes load, not just the ligaments. Weak peroneals, underactive glutes, or subtle pronation shifts can leave the joint vulnerable. In our experience, athletes whose ankles appear “fine” in isolation often show compromised foot pressure and lateral support under dynamic movement. That is why simple calf raises or basic balance drills are rarely sufficient.
Coordination and Movement Strategies
The nervous system also plays a critical role. As noted in The Resilient Athlete Book, by Dave O’Sullivan:
“When physical stress or injury occurs, your kingdom doesn’t shut down. Instead, it creates ingenious backup plans, different ways of moving to protect the affected area while keeping you functional.”
The brain develops adaptive strategies to protect the joint: subtle weight shifts, hesitations, or altered timing. If these patterns are not addressed, they become maladaptive. The ankle may appear stable, but the athlete is constantly compensating, placing stress elsewhere in the kinetic chain.
Why Basic Rehab Often Fails
Standard rehab often focuses only on pain-free movement and basic strength. In athletes, that is rarely enough. True recovery requires rebuilding lateral stability, correcting foot pressure imbalances, retraining coordination, and progressively loading the joint under sport-specific conditions. Without this approach, recurrent sprains are almost inevitable.
The ProSport Approach
With professional athletes, we combine detailed assessment with sport-specific drills. We evaluate how the ankle responds under real conditions, integrate peroneal bracing, progressive lateral loading, and coordination drills. Every session is designed around the athlete’s performance goals, ensuring that the ankle is not just “healed” but fully prepared for high-demand movement.
The aim is not simply to “recover”, it is to restore confidence, power, and unrestricted performance. This is the difference between an ankle that tolerates jogging and one that can handle pivoting, jumping, or sprinting under fatigue.
Next Steps
If an ankle keeps giving out despite rehab, it is not bad luck, it is a sign the system has not been fully rebuilt. Begin by identifying the weak links and follow a structured program that challenges stability, coordination, and load tolerance.
