頚髄症における手術前後の他覚的・自覚的重症度と健康関連quality of lifeとの関係

Pre- and Post-operative Relationships between Objective and Subjective Severity and the Health-related Quality of Life of Cervical Myelopathy Patients

目的：手術を受けた頚髄症患者における健康関連QOLの特性を明らかにすること．

対象：頚髄症患者35人と健常者30人．

方法：他覚的重症度(JOAスコア：17点法)，自覚的重症度(SSFS)，健康関連QOL(SF-8)を術前と退院時に調査した．

結果：SF-8のほとんどの項目は退院時までに有意に改善したが，その半数以上は健常者と比較して有意に劣っていた．また，手術前後ともSSFSはJOAスコアと比較してSF-8との関連が強かった．

結語：健康関連QOLは他覚的重症度ではなく自覚的重症度の改善に基づいて改善する特性が示された．

　［Aim］ The aim of this study was to clarify the characteristics of health-related QOL in surgically treated cervical myelopathy patients.　［Subjects］ Thirty-five cervical myelopathy patients and 30 healthy subjects were enrolled in this study.　［Methods］ Objective severity (JOA score), subjective severity (SSFS), and health-related QOL (SF-8) were assessed before surgery and at the time of discharge from the hospital.　［Results］ Most of the items on the SF-8 showed significant improvement postoperatively, but the results for more than half of them were significantly poorer than in the healthy subjects.　Furthermore, the SSFS scores were more closely correlated with the SF-8 scores than with the JOA scores.　［Conclusion］ The results suggested that the health-related QOL of cervical myelopathy patients is affected more by subjective severity than by objective severity.
