On physical exam, bilateral lower extremity motor function is 5/5, sensation is intact to light touch globally, patellar and Achilles reflexes are symmetric and 2+ bilaterally, and there is no clonus. He has palpable and symmetric posterior tibial and pedal pulses bilaterally. When asked to walk back and forth in the hallway, he has to stop after 100 feet due to thigh cramping and notes relief when leaning forward against the reception desk.
