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)). 2012 BC 8 http://hdl.handle.net/11104/0197126 BIOCHEMICALRESEARCHMETHODS|NEUROSCIENCES 2.400 0.386 7.5 0.0275 0.847 10653 337 86 1.208 34.12 2.27 Q2 33.76 31.256 Q3 Q3 2011 000291142600016 WOS 344 kB cav_un_epca*0257055 Journal of Neuroscience Methods 0165-0270 1872-678X Roč. 198 č. 1 2011 110 113 Elsevier
