Shell-shock and other neuropsychiatric problems

by Elmer Ernest Southard

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.

Paralysis: Hysterical? organic?

Case 429. (Gougerot and Charpentier, May, 1916.)

A man was wounded Oct. 11, 1914, on the back of the right hand. Two hours later, he was attended at the relief post. At this time, his hand was straight, with fingers extended. He said that he could not move his fingers, although there was no pain in them. Three hours after the wound, the hands swelled and the edema spread as far as the middle of the forearm. There was a long suppuration, complicated by lymphangitis. All of the fragments were removed October 26, 1914; healing was complete in three months. The swelling, however, persisted to June, 1915, and when the swelling disappeared, the hand began to show drop-wrist. The wound was sutured between the second and third metacarpals, and the X-ray showed that the bones had not been injured, nor had the nerves of the forearm muscles been touched. The situation was such that the case was catalogued “functional paralysis.”

October 5, 1915, the hand was still drooping, fingers extended, and middle finger and ring finger trembling. A slight stiffness of wrist and fingers did not interfere with movements. Extension of the wrist could be made very slightly above horizontal. Flexion was not quite complete, nor were adduction or abduction. Extension of the fingers could be performed normally, as well as that of the thumb, but flexion was not quite complete. There was a slight palmar retraction. Such were the movements that could be produced electrically. Voluntarily, flexion of the wrist was good, abduction and adduction incomplete; extension could not be executed to the horizontal position. There was a tendency to flexion of the ring finger. When the patient tried to flex the middle and index fingers, these fingers trembled but did not flex. Weak extension and abduction of the thumb but without opposition could be voluntarily performed; adduction good; flexion of the first phalanx, weak; of second phalanx, better. Slight muscular atrophy of the forearm, which was one centimeter less in circumference than the left. The hand was subject to a general atrophy; the skin reddish and moist. The X-ray showed a decalcification of all the bones of the hand and wrist; trophic disturbance of the small carpal bones although the trauma had affected only the second interosseous space. No joint lesions or periosteal thicknesses were found by X-ray. There was a slight hypesthesia of the palmar surface of the middle finger and of the index finger. The patient complained of sharp transient pains in hand and fingers.

In this case, therefore, a wound of the back of the hand produced an immediate inhibition of muscular action in the forearm, a rapid edema of the hand and arm, lasting for eight months and followed by reflex disorders.

There was a considerable diminution in faradic excitability of the flexor brevis of the thumb, the anterior cubital, the flexor brevis minimi digiti, and of the dorsal interossei, and slighter evidence of diminution of galvanic excitability in some of the muscles.
