Quantitative analysis of tremor in Minamata disease.
Applying the techniques of power spectrum and pulse correlation, we carried out a quantitative analysis of tremor in normal subjects, patients with methyl mercury poisoning (Minamata disease) and patients with other diseases. We found that tremor of methyl mercury poisoning was different from physiological tremor and the other pathological tremors in frequency and amplitude.
