Diagnosis of Lumbar Spinal Stenosis
Clinical evaluation Sometimes MRI, electrodiagnostic studies, or both Spinal stenosis is suspected based on characteristic symptoms of pain that is increased by exertion (neurogenic claudication) and relieved with sitting and/or with back flexion. Muscle strength is usually maintained, but focal weakness, sensory loss, and diminished deep tendon reflexes may be present. Calf symptoms may simulate those of intermittent vascular claudication. Vascular claudication can be differentiated by relief with rest (not position change), skin atrophy, and abnormalities in pulses, capillary refill, and vascular tests. Diagnostic tests for lumbar spinal stenosis, when needed, are Diagnosis , including MRI or CT and electrodiagnostic studies.
