Participants (n=113) who agreed to be tested by the diagnostic support tool for LSS underwent three risk tests for locomotive syndrome: a stand-up test, a two-step test, and a 25-question Geriatric Locomotive Function Scale (GLFS-25), as well as measurements of the strength of their grip, back extensor, hip flexor, and knee extensor muscles.Results: Twenty-three participants were diagnosed with LSS by the questionnaire. Results of the stand-up test in the LSS group were significantly worse than those in the no-LSS group (P=0.003). The results of the two-step test and the total score on the GLFS-25 in the LSS group were significantly worse than those in the no-LSS group (P=0.002 and P<0.0001, respectively). The stages of locomotive syndrome assessed by the stand-up test, two-step test, and the GLFS-25 were significantly worse in the LSS group than in the no-LSS group (P=0.0004, P=0.0007, and P<0.0001, respectively). Hip flexor and knee extensor strength, but not grip and back extensor strength, in the LSS group were significantly lower than that in the no-LSS group.Conclusions: LSS diagnosed using the self-reported support tool worsened the stage of locomotive syndrome in older people. Furthermore, participants with LSS had significant lower extremity weakness.Keywords: lumbar spinal stenosis, locomotive syndrome, locomotive syndrome risk test, grip strength, back extensor strength, lower extremity muscle strength
