title: Numerical evaluation of symptoms in cervical myelopathy by quantification theory III (Hayashi).
abstract: The authors applied Hayashi's quantification theory III, a mathematical approach for quantification of qualitative data to evaluate cervical myelopathy in 81 patients who had been surgically treated. More of these patients recovered from sensory disturbances than from motor disturbance. The size of the spinal canal was correlated with the severity of the preoperative symptoms of the myelopathy, but not with the surgical results. The surgical results were correlated with the duration of the disease but not with the age of the patient. The most predictable surgical result obtained by the use of multiple regression analysis was that of the leg motor symptom.
