As the pa speaks with harry, he notices that harry's tongue is moving strangely; it keeps writhing and twitching. during the physical examination, harry gags on the tongue depressor (when it is only touching his lips! ) and he has difficulty swallowing. he also shows an abnormal babinski reflex: his toes fan out when the bottom of his foot is stroked. while the remainder of his reflexes is normal, harry shows pronounced muscle weakness and abnormal spasticity— mostly in his legs, but also in his arms, though to a lesser degree.
