ObjectiveTo test the effect of human tremor detector in clinic based on the principle of photoelectrical transformation.MethodsFifty-five subjects including normal youth and elderly persons, patients with Parkinson's disease (PD), hyperthyroidism and cerebellor ataxia were tested with human tremor detector. The displacement, frequency spectrograph, velocity and acceleration of both hands in four kinds of postures and action were involved.ResultsThe physiological tremor and pathological tremor in different kinds of patients were significantly different (P<0.05). Especially in PD, both quantitive and qualitative data had a significant difference.ConclusionHuman tremor detector can provide the evidence for early diagnosis of PD.
