Frequency and amplitude were insufficient to separate between these conditions, except for the trivial distinction between normal and pathologic tremors that is already defined on the basis of amplitude. We found that waveform analysis revealed highly significant differences between normal and pathologic tremors, and, more importantly, among different forms of pathologic tremors. We found in our group of 25 patients with PT and 15 with ET a reasonable distinction with the third momentum and the time reversal invariance. A nearly complete distinction between these two conditions on the basis of the asymmetric decay of the autocorrelation function. We conclude that time series analysis can probably be developed into a powerful tool for the objective analysis of tremors.<\/jats:p>","DOI":"10.1063\/1.166084","type":"journal-article","created":{"date-parts":[[2002,7,26]],"date-time":"2002-07-26T12:36:59Z","timestamp":1027687019000},"page":"48-51","update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":54,"title":["Tremor classification and tremor time series analysis"],"prefix":"10.1063","volume":"5","author":[{"given":"G\u00fcnther","family":"Deuschl","sequence":"first","affiliation":[{"name":"Department of Neurology, University of Freiburg\/Breisgau, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michael","family":"Lauk","sequence":"additional","affiliation":[{"name":"Department of Neurology, University of Freiburg\/Breisgau, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jens","family":"Timmer","sequence":"additional","affiliation":[{"name":"Department of Physics, University of Freiburg\/Breisgau, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"317","reference":[{"key":"2024020122252534200_r1"},{"key":"2024020122252534200_r2","first-page":"419","article-title":"Exploring the functional significance of physiological tremor: A biospectroscopic approach","volume":"49","year":"1983","journal-title":"Exp.
