| Outline of Final Research Achievements |
Lumbar spinal stenosis (LSS) is the one of the locomotive disorders. Little has been reported the relationship between the natural history of LSS in the community. The purpose of this study was to assess the change of prevalence for symptomatic LSS and the dural sac cross-sectional area (DCSA) of lumbar spine with symptomatic LSS in the 10-year follow-up. Overall, 67.8% of the LSS improved their symptoms over 10 years, while 10.0% of the non-LSS subjects switched to LSS. The low back pain related QOL and LSS symptoms were correlated over the 10-year period. All subscales of the health-related QOL were not related to LSS symptoms positive or negative. The amount of change in DCSA each disc level did not change among four groups for 10 years. There results suggested that a diagnosis based solely on stenosis of DCSA by MRI was insufficient the onset of LSS symptoms 10 years later.
