neurogenic claudication
Lower extremity pain and weakness that occurs with walking due to spinal stenosis.
Full Definition
A symptom complex characterized by lower extremity pain, cramping, numbness, or weakness that develops with walking or standing and improves with sitting or flexion. Unlike vascular claudication, neurogenic claudication is relieved by spinal flexion (shopping cart sign) and may be asymmetric. The condition results from dynamic compression of neural elements during extension activities in patients with spinal stenosis. Diagnosis is confirmed through clinical presentation and imaging findings of canal narrowing.
Usage
Usage note: Distinguish from vascular claudication in documentation. Often associated with 'shopping cart sign' phenomenon.
