Chronic Ankle Instability (CAI)

What is Chronic Ankle Instability?

Chronic Ankle Instability (CAI) refers to the recurring sensation of your ankle giving way, often following an ankle sprain. This condition can disrupt your daily life, leading to repeated injuries, discomfort, and decreased physical activity. Without proper management, CAI can increase the risk of osteoarthritis in the ankle joint.

Why Does CAI Occur?

Chronic Ankle Instability typically develops after an ankle sprain that hasn’t healed correctly. Repeated sprains can weaken the ligaments around the ankle, reducing the joint’s stability. Over time, this can create a cycle of instability, making the ankle more prone to further injuries.

How Does CAI Affect You?

CAI manifests through symptoms like persistent ankle pain, swelling, and a tendency for the ankle to give way. These symptoms can severely limit your ability to participate in physical activities and even interfere with simple tasks like walking on uneven ground.

What are the Solutions for CAI?

A physiotherapist plays a crucial role in managing CAI by addressing both the symptoms and the underlying causes. Here’s how:

• Targeted Strengthening Exercises: Strengthening the muscles around the ankle joint can help stabilise the ankle, reducing the likelihood of future sprains.
• Balance and Proprioception Training: Enhancing your body’s ability to sense movement and position (proprioception) is vital for preventing further injuries. Balance exercises are a key part of this process.
• Manual Therapy: Techniques like joint mobilisation and manipulation can improve ankle function, reduce pain, and increase the range of motion.
• Education and Prevention: Your physiotherapist will guide you on activity modification, appropriate footwear, and the use of ankle taping to prevent further injuries.
• Customised Rehabilitation Programs: Each case of CAI is unique. A personalised rehabilitation plan tailored to your needs ensures a more effective recovery and a return to your desired activity level.
• Pain Management: Techniques like ice, heat, ultrasound, and electrical stimulation are used to manage pain and swelling, aiding in your recovery.

6. What exercises help with CAI?
   Exercises that strengthen the muscles around the ankle and improve balance are most effective. Your sports physiotherapist will customise your exercises specific to your ankle instability.
7. Is surgery needed for CAI?
   Surgery is occasionally required, especially in severely unstable ankles such as recurrent ankle sprains, high ankles sprains and syndesmosis injuries. Physiotherapy is usually sufficient to manage the condition. But, when your rehabilitation fails to provide your ankle with enough dynamic control, you may require an ankle reconstruction.

8. How long does it take to recover from CAI?
   Recovery time varies, but with consistent physiotherapy, many people see improvements within a few months.
9. What should I avoid if I have CAI?
   Avoid activities that place excessive strain on your ankle, like running on uneven surfaces, until your ankle is stable.
10. Can CAI lead to arthritis?
    Yes, untreated CAI can increase the risk of developing osteoarthritis in the ankle joint.

Latest Research

Recent studies emphasise the importance of early intervention in treating ankle sprains to prevent the progression to CAI. Research suggests that customised physiotherapy programs significantly improve outcomes for those with CAI, reducing the risk of further injury and improving quality of life (Hertel and Corbett, 2019),(Guo et al, 2024)

What to Do?

If you’re experiencing symptoms of Chronic Ankle Instability, consulting a physiotherapist is your first step toward recovery. They can assess your condition, create a tailored rehabilitation plan, and guide you on how to prevent future injuries.
