Paralysis: Hysterical? organic?
A soldier, 20, was wounded May 15, 1915, by a large number of shell fragments, 15 of which struck the right leg, two producing serious injuries,—the one, a penetrating wound of the popliteal space followed by stiffness of the knee, later cured by extraction of the fragments; the other, causing a deep wound at the internal malleolus. The fragment was extracted June 3, but osteomyelitis persisted and a fistulous contraction was developed in January, 1916. There was a slight equinism.
By contrast with these deep bony lesions of the right leg, on the left side a fragment had struck the dorsum of the left foot at about its middle point, along the extensors of the fourth and fifth toes. The fragment was removed toward the end of June, 1915. The wound closed in a fortnight, leaving a loose 20 mm. scar. The man complained of pains, which he called electrical, in the third and fourth toes, if one bore down on this scar, a symptom suggesting that the dorsal nerves had been injured. Immediately after the wound both legs had been paralyzed, according to the soldier. He had been able only to drag himself along on his shoulders. This indeterminate paralysis lasted three days. It may have been hystero-traumatic, or it may have been a sort of diffuse inhibition. Just after the injury, the left foot was in contracture, which gave place a month later to paralysis. Only the great toe was still able to move a little. In December, 1915, the patient still could extend and flex the toes on the left side very badly, though he could execute movements easily on the right side. There was no stiffness of joints; there were no tendon reflex disorders. There were no trophic vasomotor or secretory disturbances.
The diagnosis of hysterical paresis seemed warranted, but electrical examination showed that the troubles were organic. There was an increase in the faradic and galvanic excitability of the external popliteal nerve. The response was more sudden than normal, and there was an increase in faradic and galvanic excitability in the tibialis anticus. There was a decrease of faradic and galvanic excitability in the extensor communis of the toes and in the external peroneus.
Thus, this patient after being wounded in both feet May 15, 1915, paralyzed in both feet for a period of three days, undergoing a contracture of the left foot for a month, giving place to paralysis of foot and toes, with slow improvement from the end of July, 1915, was still in this latter state in March, 1916; though without trophic disorder, he showed faradic and galvanic over-excitability of the external popliteal nerve and of the tibialis anticus, pari passu with diminished electrical excitability for other muscles.
