Spinal Stenosis / Neurogenic Claudication

Question 1

Spinal Stenosis / Neurogenic Claudication Overview

Answer 1

• Arterial Insufficiency to tissues
• Most evident when activity occurs because of increased vascular demand on tissues

Question 2

Spinal Stenosis / Neurogenic Claudication Types

Answer 2

• Neurogenic = associated with spinal stenosis, symptoms manifested in back or sciatic nerve distribution, sometimes called pseudo claudication or cauda equina syndrome
• Vascular = common result of arteriosclerosis, arterial embolism, or thrombo-angitis

Question 3

Bicycle Test of Van Gelderen

Answer 3

• Patient seated on exercise bike and asked to peddle against resistance
• Patient started pedaling while leaning backward (if pain to butt and post thigh and tingling in affected LE then this part is +)
• Patient then asked to lean forward while continuing to pedal (if pain subsides over short period of time then test is +)
• If patient sits upright again, pain returns
• This test determines whether patient has neurogenic intermittent claudication
