Contribution of motor performance tests to the early diagnosis of Parkinson’s disease
With the help of multivariate statistical methods, we analysed the results of a motor performance test series consisting of simple subtests. We were able to differentiate almost completely between parkinsonian patients (most of whom showed only slight or very slight clinical symptoms) and age-matched controls: we found only 2% false negative diagnoses and no false positives. Thus, impairment of fine motor skills is very frequent in the early stages of the disease and standardized motor performance tests can contribute to its detection. Since we established that a deterioration of the test results is highly age-correlated for these patients, we expect that follow-up testing will further contribute to improve selectivity.
