Shell explosion: Hysterical and organic symptoms.
Case 378. (Hurst, 1917.)
A champion heavy-weight boxer, 29, was unconscious for two days after being knocked over by the explosion of a shell in December, 1914. He found at first that he could not move the right arm or left leg; and after power had returned to the limbs, he had forcible involuntary movements in the left leg whenever he tried to stand. Examined, April 1, 1915, he answered questions slowly and with slow words; the right arm was weak. When the left hand was clenched, an associated movement took place in the right hand, but not vice versa. There was, however, no diminution in the girth of the muscles. The man was unable to localize light tactile stimuli accurately. Movements of the left leg were somewhat weak, the left knee-jerk was slightly brisker than the right; ankle clonus could be obtained on the left side and Babinski second sign (paralyzed leg rising higher than the normal leg in combined flexion of thigh and pelvis). When the man tried to walk, the left leg moved rapidly from side to side round the point of contact of the toes. When the right leg moved forward, the left dragged behind in irregular movement.
Every effort to cure the patient by means of suggestion during hospital care for a month entirely failed. Although the man was easily hypnotizable, he could not be made to move his leg under the deepest hypnosis. The first whiff of ether hypnotized him, so that the method of etherization could not be used in the endeavor to control the leg movements. Over a year later, July, 1916, the patient had greatly improved mentally but was otherwise in precisely the condition that is above described.
