Fall from horse under shell fire: Crural monoplegia, hysterical. Reminiscence? Autosuggestion?
Case 286. (Forsyth, December, 1915.)
A patient of Forsyth had been exercising a high-spirited horse. Artillery fire close by made the horse leap sidewise, and the rider fell, his back striking the ground. He seemed to be curiously shaken out of proportion to the gravity of the fall. In a day or so, he lost the use of one leg.
He recalled a rather similar incident: He had taken a hand in a local uprising in a distant quarter of the world. While he was escaping up a mountain track, a rifle-shot from the enemy brought down his horse, which rolled over and threw him violently against a boulder, where the small of the back met the force of the impact. He felt intense pain and lost consciousness. Upon recovery he found he was paralyzed. At the end of several days, in a hiding-place in the rocks, he found himself still unable to move his legs. The friend who had carried him to the hiding-place refused to leave him. He thought of suicide, but then discovered that he could move: at first, the big toes, then the ankles, then the knees, and finally the hips. He was finally able to get into the saddle.
Moreover, years before, he had heard that a man who broke his back was paralyzed in the legs.
Re autosuggestion, Babinski remarks that suggestion may work in hystero-organic cases not precisely as in hysterical cases. Autosuggestion may here replace or accompany the ordinary heterosuggestion. Some temporary disturbance—a slight pain, a trivial injury, or a mere bruise—may start up a complex process of autosuggestion in which it may be difficult to unravel the part played by the patient’s own reflexes, his previous experience and beliefs (in this case, the reminiscences of a similar accident), the solicitude of his friends, and the medical examination itself. Babinski believes that hysterical paraplegia or monoplegia never appears automatically under the influence of emotion; never appears after the manner of sweating, diarrhea, or blushing.
