Evaluation of Symptoms of Lumbar Spinal Stenosis in people w
The aims of this study were to evaluate: the proportion of people reporting symptoms associated with lumbar spinal stenosis (LSS) in primary care programs for knee or hip osteoarthritis (OA) or persistent low back pain (LBP) and; the prevalence of self-reported clinical LSS in these three cohorts, according to two sets of adapted criteria.

A cross-sectional analysis of baseline data from the Good Life with osteoArthritis was done. Self-report LSS symptom questions were administered to participants with knee OA, hip OA, and persistent LBP. The prevalence of 11 LSS symptoms and clinical LSS were calculated for each cohort.

Results:
--A total of 10,234 participants were included in the analysis.

--A similar proportion of participants in each cohort were female, with a 6- and 7-year older mean age in the knee and hip cohorts compared to the back cohort.

--A greater proportion of participants with LBP reported LSS symptoms (range 11-71%) than in the hip (11-50%) and knee (8-40%) cohorts. This pattern was observed for all but one symptom.

--The same pattern was observed for the prevalence of clinical LSS with less than 10% of people in each cohort satisfying the clinical criteria.

In particular, Self-reported LSS symptoms are commonly reported by people treated in primary care for knee or hip OA, although not as frequently as reported by those with LBP.
