The Essence of Clinical Practice Guidelines for Lumbar Spinal Stenosis, 2021: 2. Diagnosis and Evaluation.

Abstract

•In the middle-aged and elderly, if pain and numbness are experienced from the buttocks to the lower limbs and the symptoms are exacerbated when walking and standing but alleviated when in the sitting and flexed positions, lumbar spinal stenosis (LSS) is very likely. Intermittent claudication is a characteristic symptom of LSS, but it is important to differentiate it from vascular intermittent claudication. •The “Diagnostic Support Tool for Lumbar Spinal Stenosis” is a convenient and useful tool for screening patients.
