Abstract:
Objective To explore the difference of the tremor of Parkinson's disease(PD) in early stage and physiological tremor by tremor analysis.Methods 14 patients with PD(group PD) and 9 cases of physiological tremor(group physiological tremor) were studied.The surface electrode of the accelerometry(Acc) was pasted at the end of certer-metacarpal of back of hand.At the same time,surface electrodes of electromyography(EMG) were pasted on the forearm flexors and extensors.The tremor graphices and myoelectric activities were recorded in 30 s with and without 1000 g bearing respectively.Tremor frequency and related myoelectric activities were analysed.Results Acc record: The main manifestations were static tremor and tremor frequency was no significant difference when with and without loading in group PD.In group physiological tremor,the main manifestations were posture or active tremor.With loading,the tremor frequency was significant reduced(P
