AB  - BACKGROUND: The Gait Assessment and Intervention Tool (GAIT) provides a valid and 
      reliable gait quality measure for adults with stroke, however a minimal 
      clinically important difference (MCID) is yet to be determined. RESEARCH 
      QUESTION: What is the GAIT MCID in community dwelling adults with a stroke 
      diagnosis? METHODS: The GAIT scores for a consecutive series of 63 adults with 
      stroke, referred for video gait assessment within an outpatient rehabilitation 
      program, were retrospectively identified from a gait laboratory database. 
      Patients were classified by Functional Ambulation Category (FAC) and had walking 
      speed measured, which classified them into one of three walking speed-based 
      ambulatory levels (I.e. household, limited community or community ambulator). 
      Linear regression models were fitted to assess the association between GAIT score 
      and FAC level and GAIT score and ambulatory level. MCIDs were determined based on 
      estimates calculated in the two models RESULTS: The FAC of patients ranged from 3 
      to 5. GAIT score was negatively correlated with FAC level and ambulatory level 
      (rho = -0.73, p < 0.001 and rho =-0.69, p < 0.001, respectively). Pairwise 
      comparisons from the models showed absolute mean differences between estimated 
      GAIT scores of 10.84 (95% confidence interval 7.59-14.09) for changes from FAC 
      level 3-4 and 12.13 (8.90-15.36) for household to limited community ambulator, 
      and 5.90 (3.44-8.37) for changes from FAC level 4-5 and 4.39 (2.01-6.76) for 
      limited community to community ambulator. The proposed MCID for FAC level 3 or 
      household ambulators is 11.48, and for FAC level 4 and 5 or limited 
      community/community ambulators is 5.19. SIGNIFICANCE: The proposed MCIDs 
      represent real changes in gait quality measured by the GAIT for adults with 
      stroke who exhibit lower or higher functional mobility levels. The MCIDs will 
      assist clinicians and researchers using the tool to determine if meaningful 
      change in gait quality has taken place for adults with stroke undergoing 
      rehabilitation.
