運動器に関する疫学調査―南会津スタディ第4報：腰部脊柱管狭窄と腰痛関連QOLとの関係（縦断研究）

Epidemiologic Study of Musculoskeletal Disorders. Minami-Aizu Study. Part 4 : One-Year-Follow-Up Study of Lumbar Spinal Canal Stenosis and Its Relation to Low-Back-Pain Related QOL

　地域住民における腰部脊柱管狭窄による症状の経時的推移とそれに伴う腰痛関連QOLの変化を検討した．腰部脊柱管狭窄の診断は，東北腰部脊柱管狭窄研究会で作成した腰部脊柱管狭窄診断用質問表を用いた．また，腰痛関連QOLは，Roland-Morris Disability Questionnaire日本語版(以下RDQ)を用いた．その結果，腰部脊柱管狭窄が軽快すると腰痛関連QOLは向上し，腰部脊柱管狭窄が出現すると腰痛関連QOLが低下することが明らかになった．この事実は，以前の横断研究において明らかになった“腰部脊柱管狭窄の存在は腰痛関連QOLを低下させる”を支持する結果であった．

　The presence of lumbar spinal canal stenosis (LSCS) was found to have a strong negative impact on low-back-pain (LBP)-related QOL in a cross-sectional study.　However, there have been no reports on the relation between the presence of LSCS and LBP-related QOL in a longitudinal study of a local population.　Based on the results of a 1-year follow-up study of LSCS and its relation to LBP-related QOL in the Minami-Aizu study, when LSCS improves, LBP-related QOL improves in parallel, and when LSCS happens, LBP-related QOL deteriorates in parallel.　These findings strongly corraborate the previous evidence that the presence of LSCS has a strong negative impact on LBP-related QOL.
