AB  - BACKGROUND: Vestibular Rehabilitation Therapists (VRT) utilize outcome measures 
      to quantify gait and balance abilities in individuals with vestibular disorders 
      (IVD). The minimal clinically important difference (MCID) in gait and balance 
      outcome measures for IVD is unknown. OBJECTIVE: The purpose of this study is to 
      estimate the MCID of the Activities-specific Balance Confidence Scale (ABC), 
      Functional Gait Assessment (FGA), and Gait Speed (GS) using distribution and 
      anchor-based methods relative to the Dizziness Handicap Inventory (DHI) in IVD. 
      METHODS: Data were collected using a retrospective chart review from two 
      outpatient Vestibular Rehabilitation (VR) clinics. Data included demographic 
      characteristics, diagnosis, VR course, and pre and post outcome measures 
      including DHI, ABC, FGA, and GS. The DHI was used to classify subjects as 
      "responders" or "non-responders" in order to calculate MCID values. RESULTS: The 
      total number of subjects analyzed for each outcome measure was 222 for the ABC, 
      220 for FGA, and 237 for GS. Subjects made statistically significant improvements 
      in ABC, DHI, FGA, and GS (p < 0.001) from pre to post VR. The MCID calculated for 
      ABC, FGA, and GS using the anchor-based approach was 18.1%, 4 points, and 
      0.09 m/s respectively. The MCIDs calculated using distribution-based approach for 
      the ABC ranged between 7.5-23.5%, FGA ranged between 1.31-4.15 points, and GS 
      ranged between 0.07 m/s-0.22 m/s. CONCLUSIONS: The anchor-based calculations of 
      the MCID of 18.1%, 4 points, and 0.09 m/s for ABC, FGA, and GS respectively for 
      IVD should be used over distribution-based calculations. This is due to strength 
      of DHI as the anchor and statistical analysis. VRT and researches can use these 
      values to indicate meaningful changes in gait and balance function in IVD.
