THE SIGNIFICANCE OF USING MODIFIED WEBSTER SCALE IN EVALUATING THE EFFECT OF SURGICAL TREATMENT ON PARKINSON DISEASE / 解放军医学杂志

ABSTRACT

With Modified Webster Scale, 42 patients suffered from Parkinson disease were examined before and after operation. The symptoms were divided into 10 groups. 1～10 points was taken as slight disability, 11～20 as medium, and 21～30 as severe. Improvement less than 25% was taken as no effect, 26%～50% as effective, 51%～75% as significantly effective, and over 75% as very significantly effective. The score was (19 90?5 27) preoperatively and (10 57?6 10) postoperatively. The mean improvement was (8 95?3 37). Very significantly effective result was obtained in 4 cases (9 5%), significantly effective sesult was obtained in 17 cases (40 5%), and effective result was obtained in 16 cases (38 1%). The total effective rate was 88 1%. One target coagulation was performed in 34 cases, the mean improvement was in (8 59?3 53). Two target coagulation on one side was performed in 8 patients, the mean improvement was in (10 00?4 14). No significant difference was found between these two groups statistically. It is suggested, for patients with Parkinson disease in whom drug treatment is not efficacious or because of increased side effect, Modified Webster Scale is useful to evaluate the effect of surgical treatment. This scale is very easy to use especially for neurosurgeons.
