Electrophysiological methods and motor performance tests are shown to be helpful to the early diagnosis of Parkinson’s disease. The most sensitive out of five motor tests studied here is visuo-manual tracking. Tremor recordings allow to differentiate between physiological and pathological tremor. An enhancement of long-latency reflexes may precede the development of parkinsonian symptoms on the hitherto unaffected side in unilateral parkinsonism. The combination of motor function tests with tremor and long-latency reflex recordings is likely to be more sensitive than any single test.
