How can ischemic claudication be differentiated from pseudo claudication?

• A. Symptoms are relieved immediately with rest
• B. Symptoms worsen with standing
• C. Symptoms are relieved only with analgesics
• D. Symptoms persist at rest

Answer: (A)

Ischemic claudication arises when leg muscles demand more blood during walking than the narrowed arteries can supply. Stop exercising reduces oxygen demand, so the pain resolves quickly. This immediate relief with rest is the hallmark that differentiates vascular claudication from pseudo claudication, which stems from nonvascular causes such as spinal or musculoskeletal problems and does not consistently improve with rest alone (often needing posture changes or other factors to relieve symptoms).
