Clinician-reported measures included the Japanese Orthopaedic Association (JOA) score, a thoracic-adapted JOA subtotal (JOAt), and the modified JOA (mJOA). Patient-reported outcomes included the Japanese Orthopaedic Association Cervical Myelopathy Evaluation Questionnaire (JOACMEQ) and EuroQOL 5-dimension (EQ-5D). Assessments were performed preoperatively and at 3\u20136 months postoperatively. Internal responsiveness was evaluated using Wilcoxon\u2019s r, test\u2013retest reliability using ICC(1,1), and construct validity using Spearman\u2019s correlation with EQ-5D.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Fifty-one patients were included (mean age 65.6 years; 59% male). Significant postoperative improvement was observed across major clinician-reported and patient-reported outcomes. Large internal responsiveness was demonstrated for JOA (r=0.64), JOAt (0.63), mJOA (0.68), and JOACMEQ lower-extremity function (LF) (0.59). Test\u2013retest reliability was high for JOA, JOAt, mJOA, JOACMEQ-LF, and EQ-5D (ICC range 0.78\u20130.85). JOACMEQ-LF showed the strongest construct validity with EQ-5D at both baseline (\u03c1=0.62) and follow-up (\u03c1=0.72).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>JOAt, mJOA, and JOACMEQ lower-extremity function demonstrated robust psychometric performance in thoracic myelopathy.
