Predictors of objectively measured walking capacity in people with degenerative lumbar spinal stenosis

摘要: BACKGROUND: Identifying factors associated with walking capacity in people lumbar spinal stenosis (LSS) may provide a better understanding of neurogenic claudication and inform future rehabilitation research. OBJECTIVE: To examine objectively measured sample LSS self-reported limitations. METHODS: Participants included 49 individuals (65.8 years ± 10) who were at least 45 age clinically diagnosed confirmed on MRI or CT imaging. All participants completed Self-Paced Walking Test visual analog pain scales body diagrams before immediately after walking. Questionnaires the Physical Function Symptom Severity Scales Swiss Spinal Stenosis Questionnaire, Oswestry Disability Index (ODI) Health Utilities Index. Univariate linear relationships examined, followed by development multivariate regression model distance (m) as dependent variable. A post-hoc analysis was also conducted including post-test symptom variables. RESULTS: Variables retained from univariate analyses leg pain, pre-test severity, ODI, balance problems, quality life. When these variables considered for final model, only ODI problems (R 2 = 0.33). Other than balance, none entered into model. Post-hoc found presence severity to be most highly distance. In an explanatory considering two post-walking factors, added 0.42). CONCLUSIONS: Factors self-reported, pain-related function (ODI), following
