Objective[edit | edit source]

The Cumberland Ankle Instability Tool (CAIT) is a 9-item 30-point scale that numerically measures the presence and severity of functional ankle instability.[1]

Intended Population[edit | edit source]

CAIT is a valid and reliable tool used to assess the severity of functional ankle instability, measure treatment outcomes, and monitor progress among individuals with chronic ankle instability.[1]

Cross Cultural Adaptations[edit | edit source]

Originally designed by Hiller et al[1] in English, the CAIT has been translated and validated in other languages:

Method of Use[edit | edit source]

Scoring[edit | edit source]

The nine items of CAIT generate a total score of 30.

  • 0 indicates an extreme functional ankle instability
  • 30 points indicates a stable ankle


The original study established a cutoff score of ≤ 27 to identify those with chronic ankle instability, however, a recent study by suggest
