The reflexes were as follows: While thetendon and periosteal reflexes were absentin the arm and hand, they were active inthe lower extremities but not pathologicallyincreased. There was neither foot nor patellarclonus; on tapping the tibia there were nocontractions of the quadriceps. The plantarreflexes were normal; the reflexes of theabdominal walls were produced only bystroking the skin over the lower part of theabdomen. There were

There was neither foot nor patellarclonus; on tapping the tibia there were nocontractions of the quadriceps. The plantarreflexes were normal; the reflexes of theabdominal walls were produced only bystroking the skin over the lower part of theabdomen. There were no disturbances of coordina-tion, tremor, or other motor irritative phe-nomena. The gait was unchanged. Thebladder, the rectum, and the genital appa-ratus acted normally. In addition, a careful testing of sensa-tion in the trunk and extremities showedthat the anterior line of thermo-anesthesia extended to the seventh rib in the mammillary line, while sensibility to heat increased to the navel, that is, hot water was felt as Fig. 175.—Syringomyelia(A man, aged 25). SYRINGOMYELIA 585 Severe irritative pain from firm pinching was not felt above the eighth rib, but wasevoked lower down. Still lower down sharpness and dulness could not be distinguished. There was complete analgesia in the hack from the middle of the neck down to theeleventh rib on the right, and to the tenth rib on the left side. Examination of the other organs of the body elicited no recognizable the exception of the finger-joints which were stiff, the joints as well as the bones,tendons, and ligaments were normal. This patient was of medium size, of strong bony frame, the muscles and fatty tissueshowing a moderate degree of nutrition. The skin and mucous membranes were pale. There were no cicatrices upon the penis; a few cubital and axillary glands weresomewhat larger than normal. The history showed that the parents of the patient died early, of unknown diseases,and that two of his brothers
