Construction and testing of a Cerebellar Involvement Scale

1 June 1990

Abstract

In today's medical settings, cerebellar patients are treated by a wide variety of health professionals, and physical therapists are increasingly assuming a major role in the rehabilitation of these patients. Not only does disagreement about the deficits one may expect to observe in patients with well defined and localized cerebellar lesions exist, but no standard assessment tool is available, and each patient is usually evaluated with a wide variety of methods. This study constructed and investigated a cerebellar assessment tool, the Cerebellar Involvement Scale, and compared the scores obtained from it with estimates of involvement made by each of the subjects' primary physician. This study also investigated two characteristics described within the professional literature having to do with the type of functional deficits one may expect to find in patients with localized cerebellar lesions. The first characteristic was whether or not lateral neocerebellar lesions would produce hypotonicity, dysmetria, and dysdiadochokinesia, and midline lesions will result in balance/postural control problems and gait disturbances. The second characteristic was whether or not unilateral neocerebellar lesions result in ipsilateral functional deficits. The data generated were difficult to extrapolate to generalized conclusions due to the low number of subjects (n=3) involved, therefore descriptive statistical techniques were used to display the information.
