• Identifying and quantifying chronic ankle instability (CAI).
• Evaluating functional deficits following lateral ankle sprains.
• Monitoring response to neuromuscular rehabilitation (proprioceptive training).

The CAIT has high test-retest reliability and is sensitive to the sensation of "giving way" which is the hallmark of chronic instability.

• Minimum Clinically Important Difference (MCID): ~3 points.
• The tool evaluates both physical and subjective components of stability.
• Useful for differentiating between "mechanical" and "functional" instability.

• Score ≤ 27: Implement a 6-12 week neuromuscular training program (balance, agility, plyometrics).
• Score ≤ 20: Consider mechanical evaluation for structural ligamentous laxity (Anterior Drawer, Talar Tilt tests).
• Post-Rehab: Aim for a 3-5 point increase to signify meaningful improvement.
