METHODS: A soft-decision wavelet-based decomposition technique is applied with 8 decomposition stages to estimate the power spectral density of accelerometer and surface EMG signals (sEMG) sampled at 800 Hz. A discrimination factor between physiological tremor (PH) and pathological tremor, namely, essential tremor (ET) and the tremor caused by Parkinson\u2019s disease (PD), is obtained by summing the power entropy in band 6 (B6: 7.8125\u20139.375 Hz) and band 11 (B11: 15.625\u201317.1875 Hz). RESULTS: A discrimination accuracy of 93.87% is obtained between the PH group and the ET &amp; PD group using a voting between three results obtained from the accelerometer signal and two sEMG signals. CONCLUSION: Biomedical signal processing techniques based on high resolution wavelet spectral analysis of accelerometer and sEMG signals are implemented to efficiently perform classification between physiological tremor and pathological tremor.<\/jats:p>","DOI":"10.3233\/thc-191947","type":"journal-article","created":{"date-parts":[[2020,4,7]],"date-time":"2020-04-07T13:55:56Z","timestamp":1586267756000},"page":"461-476","source":"Crossref","is-referenced-by-count":17,"title":["Discrimination of physiological tremor from pathological tremor using accelerometer and surface EMG signals"],"prefix":"10.1177","volume":"28","author":[{"given":"A.","family":"Hossen","sequence":"first","affiliation":[{"name":"Department of Electrical and Computer Engineering, Sultan Qaboos University, Al-Khoud, 123 Muscat, Oman"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"G.","family":"Deuschl","sequence":"additional","affiliation":[{"name":"Department of Neurology, University of Kiel, D-24105 Kiel, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"S.","family":"Groppa","sequence":"additional","affiliation":[{"name":"Department of Neurology, Movement Disorders and Neurostimulation, Biomedical Statistics and Multimodal Signal Processing, University Medical Center of Johannes Gutenberg-University Mainz, 55131-Mainz, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"U.","family":"Heute","sequence":"additional","affiliation":[{"name":"Institute for Circuit and System Theory, Faculty of Engineering, University of Kiel, D-24143 Kiel, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M.","family":"Muthuraman","sequence":"additional","affiliation":[{"name":"Department of Neurology, Movement Disorders and Neurostimulation, Biomedical Statistics and Multimodal Signal Processing, University Medical Center of Johannes Gutenberg-University Mainz, 55131-Mainz, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","reference":[{"key":"10.3233\/THC-191947_ref1","doi-asserted-by":"crossref","first-page":"1545","DOI":"10.1093\/brain\/123.8.1545","article-title":"Physiological and pathological tremors and rhythmic central motor control","volume":"123","author":"McAuley","year":"2000","journal-title":"Brain"},{"issue":"1","key":"10.3233\/THC-191947_ref3","doi-asserted-by":"crossref","first-page":"48","DOI":"10.1063\/1.166084","article-title":"Tremor classification and tremor time series analysis","volume":"5","author":"Deuschl","year":"1995","journal-title":"CHAOS"},{"key":"10.3233\/THC-191947_ref4","doi-asserted-by":"crossref","first-page":"371","DOI":"10.1016\/j.mcna.2008.09.002","article-title":"Movement disorders","volume":"93","author":"Harris","year":"2009","journal-title":"Med Clin North America"},{"key":"10.3233\/THC-191947_ref5","doi-asserted-by":"crossref","first-page":"2","DOI":"10.1002\/mds.870131303","article-title":"Consensus statement of the movement disorder society on tremor, Ad Hoc Scientific Committee","volume":"13","author":"Deuschl","year":"1998","journal-title":"Mov Disorder"},{"key":"10.3233\/THC-191947_ref6","first-page":"499","article-title":"Parkinson\u2019s disease is over diagnosed clinically at baseline in diagnostically uncertain cases: A 3-year European multicenter study with repeat [(123)] FP-CIT SPECT","volume":"24","author":"Marshall","year":"2008","journal-title":"Mov Disord"},{"key":"10.3233\/THC-191947_ref7","doi-asserted-by":"crossref","first-page":"469","DOI":"10.1007\/s00702-007-0851-0","article-title":"[(123)I]-FP-CIT SPECT and old faction test in patients with combined postural and rest tremor","volume":"115","author":"Djaldetti","year":"2008","journal-title":"J.
