AB  - PURPOSE: Minimum clinically important difference (MCID) represents the smallest 
      change in an outcome measure recognized as clinically meaningful to a patient and 
      is one of the most important psychometric parameters for assessing the 
      postoperative results of spinal surgery. The purpose of the present study was to 
      elucidate MCIDs for four common outcome measures used for degenerative cervical 
      myelopathy in the context of patients undergoing laminoplasty. METHODS: We 
      retrospectively reviewed a consecutive series of cervical laminoplasties in a 
      single academic institution. Pre- and postoperative Japanese Orthopaedic 
      Association Cervical Myelopathy Evaluation Questionnaire (JOACMEQ), Short Form-36 
      (SF-36), Neck Disability Index (NDI), and EuroQOL (EQ-5D) scores were obtained. 
      Patients were also asked to answer the anchor question regarding satisfaction 
      with treatment, and the anchor-based method was used to determine cut-off values 
      for MCIDs. RESULTS: A total of 101 patients were included in the analysis. All 
      outcome scores showed significant improvement postoperatively, with the exception 
      of JOACMEQ bladder function score and SF-36 mental component summary score. Most 
      patients (66%) were at least "somewhat satisfied" with treatment results. 
      Receiver operating characteristic curve analyses revealed MCIDs of 2.5 for 
      JOACEMQ cervical spine function, 13.0 for upper extremity function, 9.35 for 
      lower extremity function, 9.5 for QOL, 3.9 for SF-36 physical component summary 
      score, 4.2 for NDI, and 0.0485 for EQ-5D. CONCLUSION: The MCIDs of four outcome 
      measures were determined for patients undergoing cervical laminoplasty. These
