The purpose of this paper is to predict the prognosis in cervical spondylotic myelopathy (CSM). Multivariate analysis to evaluate the weight of various factors which influence the postoperative results of CSM. The subjects were 251 patients with CSM. We performed the method of discriminant analysis of quantification theory type 1 and multiple regression analysis using 10 parameters.
Following results were obtained.
1. The factors which influence the postoperative results were, in order of weight, the duration of symptoms, function of the lower limb movement, sensory of the body, the anteroposterior diameter of cervical canal, bladder disfunction, function of the upper limb movement and age.
2. Multiple correlation coefficients were 0.78 on the methods of discriminant analysis of quantification theory type 1, 0.73 on multiple regression analysis.
On the base of this results, most cases with CSM will be able to predict the prognosis.
