AB  - OBJECTIVE: To establish the minimal detectable change (MDC) and minimal 
      clinically important difference (MCID) for the Cumberland Ankle Instability Tool 
      (CAIT) in a population with chronic ankle instability (CAI). DESIGN: Experimental 
      cohort. SETTING: Laboratory. PARTICIPANTS: A convenience sample of individuals 
      with CAI (N=50; 12 men; 38 women; episodes of giving way, 5.84+/-12.54mo). CAI 
      inclusion criteria included a history of an ankle sprain, recurrent episodes of 
      giving way, and a CAIT score </=25. INTERVENTIONS: Participants completed 
      demographic information, an injury history questionnaire, and the CAIT. 
      Participants then either participated in 4 weeks of wobble board balance 
      training, resistance tubing strength training, or no intervention. After 4 weeks, 
      participants recompleted the CAIT and recorded their global rating of change 
      (GRC). MAIN OUTCOME MEASURES: Dependent variables were pre- and postintervention 
      scores on the CAIT and postintervention GRC. The MDC with 95% confidence interval 
      was calculated. A receiver operating characteristic (ROC) curve identified the 
      optimal CAIT cut point (MCID) between improved and unimproved individuals on the 
      basis of their GRC. The area under the curve was used to identify a significant 
      ROC curve (alpha=.05). RESULTS: The average CAIT score preintervention was 16.8+/-5.6, 
      and postintervention, it was 20.0+/-5.2. Thirty-one participants (62%) rated 
      themselves as improved on the GRC scale, whereas 19 (38%) were not improved. The 
      ROC curve was significant (area under the curve, .797; P=.001), indicating that 
      the CAIT change score significantly predicted clinical status. The MDC was 3.08, 
      and the MCID was >/=3 points. CONCLUSIONS: The CAIT has an MDC and MCID of >/=3 
      points. When CAIT scores are used to assess patient change over time, these 
      scores should be used as a minimum threshold to indicate detectable and 
      clinically meaningful improvement.
