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.

--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.
