Evaluation of Efficacy of Chotosan for the Treatment of Patients with Headache by Multiple Regression Analysis / 日本東洋医学雑誌

ABSTRACT

We evaluated the efficacy of chotosan for headache patients via multiple regression analysis. The subjects were 46 patients with headache (31 migraine, 14 tension-type, and1combination headache), consisting of 1 3males and 33 females, mean age 48 years (range 19-77 years), who were treated with chotosan according to their Sho (symptoms) for more than1month. The relationships between the improvement of headache and 38 factors, including age, sex, height, body weight, hypertension and other symptoms noted upon first medical examination, were examined through multi-dimensional cross-sectional analysis. Morning headache, dizziness, insomnia, body weight, tinnitus and vasodilatation of sublingual veins were significant factors. Morning headache is traditionally an indication for the use of chotosan, and our results support its efficacy for this purpose. Three factors, i.e. morning headache, vasodilatation of sublingual veins and stiff shoulder, were the best subset of explanatory variables. Stiff shoulder is a key symptom for the application of chotosan, while stiffness in the back is a key symptom for the application of yokukansan.
