title: Minimal clinically important difference of the lower-extremity fugl-meyer assessment in chronic-stroke.
abstract: The Minimal Clinically Important Difference (MCID), the smallest difference in the treatment outcome, augments both clinical and research practice. The MCID of the Fugl-Meyer assessment: Lower extremity (FMA-LE), an important motor measure in stroke, is not known.
  
  
  
  To estimate MCID score of FMA-LE using an anchor-based approach in chronic poststroke hemiparetic (>6 months) stroke subjects.
  
  
  
  
  
  
  
  A prospective, observational study.
  
  
  
  Occupational therapy department of a rehabilitation institute.
  
  
  
  Sixty-five poststroke hemiparetic subjects (Mean age = 44.22 years, 42 men, Mean poststroke duration = 16.42 months).
  
  
  
  The conventional motor therapy based on neurophysiological approaches was provided for the affected lower extremity (30 sessions, 45 min each, 3/week).
  
  
  
  FMA-LE, Functional ambulation classification (FAC), and global rating of patient-perceived changes (GRPPC).
  
  
  
  The estimated MCID of FMA-LE was found to be a score of 6 using both FAC (sensitivity 90, specificity 94) and GRPPC (sensitivity 87, specificity 91).
  
  
  
  In chronic poststroke hemiparetic subjects, the computed MCID of FMA-LE is a score of 6. The subjects who achieve a change in a score of 6 on FMA-LE would perceive a meaningful recovery of lower-extremity function than those who do not. The reference value may be utilized in stroke rehabilitation.
