Results showed that the frequencies of tremor measured with TremAn and with accelerometry are closely related, at taining agreement with lesst han 0.1 Hz difference in 80% and less than 0.5 Hz in 94% of measured samples. The reproducibility of frequency measurements using TremAn was comparable to the accelerometry, with the TremAn/accelerometry ratio of measurement error standard deviations equal to 0.99(95% confidence interval(0.84,1.17)).
