It appears that this patient had been wounded in September, 1914, and that the paralysis had developed five months later. Before the development of this paralysis, there had been simply a meiopragic state.
Without perforating the hand, the bullet had remained in the wound, being excised therefrom three months after the trauma.
In January, 1916,—that is, some sixteen months after the injury and eleven months after the recovery of the paralysis,—the vasomotor disorder and the hypothermia, and the faradic, voltaic and mechanical over-excitability of the hand and forearm muscles, were in evidence. Hypotonia was marked, permitting an overflexion of the hand upon the forearm. If the patient moved his forearm, the affected hand would hang and oscillate inertly; likewise in walking, seeming to obey only the laws of physics.
In May, 1916, the patient was invalided and found to be still in possession of the above-mentioned signs. Similar phenomena have been found in the main figée acrocontracture, and main d’accoucheur, and belong, in the opinion of Babinski, to a group which is neither hysterical nor organic in the ordinary sense of the terms. Vasomotor and thermic phenomena are in the foreground of the picture, and are, in fact, practically constant, though they vary somewhat in degree. They react abnormally to the temperature of the surrounding medium; there is undoubtedly a local perturbation of the vasomotor and heat-regulating mechanism. There is also certain evidence of vascular spasm. The vasomotor and thermic disorders run parallel with the mechanical over-excitability of the muscles and the slowness of the response.
Chloroform to demonstrate asymmetry of reflexes.
Case 423. (Babinski and Froment, 1917.)
A soldier, 26, sustained, September 22, 1914, a bullet injury of the right calf. There was no fracture, as X-ray showed, but healing was slow, taking no less than three months. The right knee-jerk was a little stronger and a little sharper than the left, but the difference was controversial; and the difference between the two Achilles reflexes was still more doubtful.
Chloroformed October 10, 1915: As the patient was going to sleep, even before the phase of excitation and motor agitation had passed, the two knee-jerks and left Achilles jerk had disappeared. They grew rapidly less marked before disappearing, and none of the tendon reflexes presented any phase of exaggeration while the patient was going under. At this point anesthesia was arrested. The right Achilles reflex, which had not disappeared, was sharply defined. It was even stronger than in the normal state and polykinetic. During the whole phase of awaking from the chloroform, the right Achilles reflex remained strong and polykinetic, without, however, any ankle clonus. Thus, the difference between the two Achilles reflexes became indisputable; also the right knee-jerk reappeared before the left, and became stronger without any patellar clonus. At this time, the difference between the two knee-jerks was sharp and beyond cavil. This status, in which the knee-jerk and Achilles reflexes were asymmetrical, lasted about ten minutes after anesthesia ceased and lasted a little longer for the knee-jerks than for the Achilles jerks.
