OBJECTIVE: To investigate the associations between these factors and clinical symptoms in LSS patients. METHODS: We recruited 154 patients with LSS scheduled for surgery. Patient-reported outcome measures and imaging evaluation including clinical symptoms, psychosocial factors, CS-related symptoms, and radiological classifications. Spearman\u2019s rank correlation coefficient and multiple regression analyses were employed. RESULTS: Spearman\u2019s correlation revealed CS-related symptoms positively correlated with low back pain (r= 0.25, p&lt; 0.01), leg pain (r= 0.26, p&lt; 0.01), and disability (r= 0.32, p&lt; 0.01). Pain catastrophizing positively correlated with leg pain (r= 0.23, p&lt; 0.01) and disability (r= 0.36, p&lt; 0.01). Regression analysis showed that pain catastrophizing was associated with disability (\u03b2= 0.24, 95%CI = 0.03\u20130.18), and CS-related symptoms with low back pain (\u03b2= 0.28, 95%CI = 0.01\u20130.09). Radiological classifications were not associated with clinical symptoms. CONCLUSION: Our findings suggest that psychosocial factors and CS-related symptoms, rather than radiological factors, seem to contribute to clinical symptoms in patients with LSS.<\/jats:p>","DOI":"10.3233\/bmr-230093","type":"journal-article","created":{"date-parts":[[2023,11,7]],"date-time":"2023-11-07T13:04:49Z","timestamp":1699362289000},"page":"369-377","source":"Crossref","is-referenced-by-count":6,"title":["Influence of radiological factors, psychosocial factors, and central sensitization-related symptoms on clinical symptoms in patients with lumbar spinal canal stenosis"],"prefix":"10.1177","volume":"37","author":[{"given":"Yuzo","family":"Ashida","sequence":"first","affiliation":[{"name":"Department of Rehabilitation, Sapporo Maruyama Orthopedic Hospital, Sapporo, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Takahiro","family":"Miki","sequence":"additional","affiliation":[{"name":"PREVENT Inc., Nagoya, Japan"},{"name":"Graduate School, Hokkaido University, Sapporo, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yu","family":"Kondo","sequence":"additional","affiliation":[{"name":"Department of Rehabilitation, Sapporo Maruyama Orthopedic Hospital, Sapporo, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tsuneo","family":"Takebayashi","sequence":"additional","affiliation":[{"name":"Department of Orthopedic, Sapporo Maruyama Orthopedic Hospital, Sapporo, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","reference":[{"key":"10.3233\/BMR-230093_ref1","doi-asserted-by":"crossref","unstructured":"Wu A-M, Zou F, Cao Y, Xia D-D, He W, Zhu B, et al.
