During the next few days he complained of violent pains in his left knee-joint and in the ankle-joint, but he remained in good spirits and full of confidence. Accordingly, in five days the plaster was removed and the contracture in the knee-joint was found to be completely absent; the knee was easily movable. The ankle-joint was but slightly movable. He could accomplish slight active flexion of the knee-joint while lying in bed, and the toe-joint had already, before the narcosis, been both actively and passively mobile. After a few days, exercises in walking were begun. The patient had a little difficulty with his left knee-joint in walking, walking in fact as if with knock-knee. The foot was not well raised from the ground on account of the persistent stiffness of the ankle-joint. Walking, however, improved daily. He walked for three hours, resting at intervals. A sensory examination showed that the upper limit of the analgesia had come down five centimeters from its former level, now occupying the left foot and leg up to the junction of the lower with the middle third. There was now a zone of anesthesia interposed between the normal skin of the upper thigh and the anesthetic-and-analgesic skin of the lower thigh and leg. Upon the posterior aspect of the leg, the analgesia and anesthesia had disappeared to a point at about the middle of the upper thigh. About five weeks after the narcotic experiment, the extended left leg could be actively raised while lying in bed, up to the full extent, with slight tremors. The patient described himself as fatigued by the active movements of this leg. The ankle-joint remained less effective. There was still a trace of resistance to passive movements. Although the passive movements of the toes were normal, active movements of these were weak and hard to execute. There was still a trace of difficulty at the knee in walking and the gait was awkward, trepidant, precipitate. He could get about without a cane, however. If unobserved, his posture was more certain and free. If he exerted himself hard, severe parietal headache on the right side would develop. It was then proposed to the patient that another narcosis would rid him of the stiffness in his ankle-joint. He feared narcosis and was told that regular and energetic voluntary movements would also rid him of the stiffness. These will exercises consisted in his directing his whole attention to his left ankle-joint until he felt it. Then he was given the command: “Let go the joint”--whereupon he would take his attention away from the ankle-joint at once. In this way, he was told, his will would make the ankle-joint mobile. Meantime he was given twice daily a gram of bromophenacetine for his parietal headache. The result was a rapid recovery. There were still a few traces of difficulty at date of report. The zone of sensory loss had retreated to the ankle, with a cuff-like zone of hypalgesia above the definite zone of analgesia and anesthesia.
