Study Notes
Characteristics of Chronic Ankle Instability (CAI)
- CAI is characterized by chronic episodes of ankle instability or giving way, with repeated pain over the anterior lateral ankle following even minor ankle sprains.
- It is often associated with decreased proprioceptive awareness, supinated foot type, and previous episodes of ankle sprains.
Risk Factors for CAI
- Decreased proprioceptive awareness
- Supinated foot type
- Previous episode of ankle sprain
- Participation in rigorous sports that involve end-range of motion, twisting, and pivoting
Observations in CAI
- Patho-mechanical impairments
- Sensory-perceptual impairments
- Motor-behavioral impairments
- Patients rarely have repeated swelling and discoloration like they did on their initial LAS event
Examination of CAI
- No specific test for CAI
- Anterior Drawer test, Reverse Anterior Drawer Test, and Talar tilt test are still used to determine the level of instability
- Patient perception matters - if they feel their ankle is unstable, they most likely have CAI
Management of CAI
- Bracing may be needed to functionally allow the patient to participate in sports with CAI
- Initially, bracing is not as critical as in acute LAS, but may be necessary for functional maintenance
