Summary
Clinical and electrophysiological characteristics of tremor and long-latency reflexes in hand muscles have been investigated in patients with Parkinson’s disease (PD) at early stages of the disease with mostly hemiparkinsonian symptoms. The tremors in the early stage of PD are often untypical in two respects: firstly the resting tremor frequencies are often higher than in case of advanced disease which seems to be a specific characteristic of early PD; secondly the combination of resting and postural tremor is rather common in early PD. Enhancement of long-latency reflexes at the clinically unaffected side may be found suggesting that this can be an early electrophysiological sign of the disease.
