When patient walked, the left arm swung helpless without sign of innervation or any tonus. Abduction of the shoulder could also not be performed, though a slight flexion of the forearm shortly began to be demonstrable. If the patient inclined his head to the right, extended his hand at the wrist, and flexed the fingers forcibly, he could then flex the forearm somewhat, and a slight tension of the biceps and supinator longus developed. Sometimes fibrillary tremors developed in deltoid and biceps.

Of course a transient peripheral palsy can be produced by pressure of the radial nerve without any change of electrical excitability, but such a change is not associated with atrophy.

Neuritis and poliomyelitis producing an Erb’s palsy without any effect upon the electrical reactions is an hypothesis not to be entertained.

Accordingly, the hypothesis of psychogenic or hysterical palsy may be set up. Yet an atonic atrophic palsy with loss of tendon reflexes (supinator) is inappropriate. According to Oppenheim, this case falls into the category of the arthrogenic atrophies. A simple muscular atrophy may follow disease of joints and bones. However, such cases have rarely shown a complete palsy, as in Oppenheim’s case.

In short, we return to the old doctrine of reflex paralysis, conceiving that a stimulus passing from the periphery influences the gray matter in its trophic functions.

How much effect had the psyche upon this condition? The patient had stuttered from childhood and had sustained a fracture of the skull at 9, following which his school work, especially mental arithmetic, had been poor. The lack of psychic inhibitions may play some part in the situation, but on the whole, the reflex hypothesis is preferred by Oppenheim, the nerve conceived to be dynamically affected, the muscles organically.

Paralysis: Hysterical? organic?

Case 428. (Gougerot and Charpentier, May, 1916.)

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.
