Case 291. (Roussy and Lhermitte, 1917.)

A sergeant in a regiment of cuirassiers was observed at Villejuif, January 25, 1915. He had lost power on the left side as a result of fatigue and emotion, November, 1914. He had a complete paralysis of the left arm and a paresis of the left leg. There was an anesthesia of hysterical type in the left arm, and also of the left leg as far as the middle of the thigh. He dragged his leg in walking (démarche en draguant: the toe is dragged along the ground, the trunk is bent forward, and at every step plunges somewhat toward the paralyzed side. The patient is able to walk, however, by means of a cane or crutches. This walk is characteristic of hysterical hemiplegia. According to Roussy and Lhermitte, the number of cases of hysterical hemiplegia (better, hemiparesis) is not large). The plantar reflexes on both sides were those of flexion. Upon treatment (not specified), at the end of six months he went back to service in the cavalry.

The point of note in this case is that this patient had had a precisely similar phenomenon on the same side, which lasted a month, at the age of sixteen years and a half. It is noteworthy that in this case there was no traumatism and only the factors of fatigue and emotion to serve as an occasion for the hemiplegia. In fact, hysterical hemiplegia is said very rarely to follow physical trauma to an extremity. There are, however, some cases in which hemiparesis follows a slight head wound, particularly if over the region controlling the paralyzed limbs.

During the six-months’ course of successful treatment, no atrophy of limbs appeared, and there was never any inequality of the reflexes.
