AB  - OBJECTIVE: To determine the Physical Component Summary (PCS) score's minimal 
      clinically important difference (MCID) on the Short Form 36 (SF-36) for people 
      with stroke. METHODS: We conducted secondary analysis of data from a large 
      randomized controlled trial (N = 400) in the post-hospital discharge phase of 
      stroke rehabilitation with outcome measurement 6 and 12 months following stroke. 
      Three methods were used for estimating the MCID: two anchor and one distribution. 
      Method 1 compared SF-36 PCS scores at 12 months for responses to the SF-36's 
      Perceived Health Change (PHC) question. Method 2 compared the change in PCS score 
      between 6 and 12 months for responses to the PHC question. Method 3 used Cohen's 
      method to estimate the MCID from the PCS score distribution. RESULTS: Method 1: 
      the mean PCS score increased by 3.0 units (95% confidence interval [CI] 2.2-3.9) 
      for each unit change in the PHC question. Method 2: the mean change in PCS score 
      increased by 2.1 units (95% CI 1.4-2.8) for each unit change in the PHC question. 
      Method 3: the MCID was estimated to be 1.8 units. CONCLUSIONS: Our estimate of 
      the MCID for the PCS in patients with stroke was 1.8 to 3.0 units.
