The severity of tremor can be evaluated using clinical rating scales, accelerometry, or electrophysiology. Clinical scores are subjectively given, may be affected by intra- and interevaluator variations due to different experience, delays between consultations, and subtle changes in tremor severity. Existing medical devices are not routinely used: they are expensive, time-consuming, not easily accessible. We aimed at showing that a smartphone application using the accelerometers embedded in smartphones is effective for quantifying the tremor of patients presenting with essential tremor. &lt;b&gt;&lt;i&gt;Methods:&lt;\/i&gt;&lt;\/b&gt; We developed a free iPhone\/iPod application, Itremor, and evaluated different parameters on 8 patients receiving deep brain stimulation of the ventral intermediate nucleus of the thalamus: average and maximum accelerations, time above 1 &lt;i&gt;g&lt;\/i&gt; of acceleration, peak frequency, typical magnitude of tremor, for postural and action tremors, on and off stimulation. &lt;b&gt;&lt;i&gt;Results:&lt;\/i&gt;&lt;\/b&gt; We demonstrated good correlations between the parameters measured with Itremor and clinical score in all conditions. Itremor evaluation enabled higher discriminatory power and degree of reproducibility than clinical scores. &lt;b&gt;&lt;i&gt;Conclusion:&lt;\/i&gt;&lt;\/b&gt; Itremor can be used for routine objective evaluation of essential tremor, and may facilitate adjustment of the treatment.<\/jats:p>","DOI":"10.1159\/000369354","type":"journal-article","created":{"date-parts":[[2015,2,18]],"date-time":"2015-02-18T07:55:31Z","timestamp":1424246131000},"page":"94-101","source":"Crossref","is-referenced-by-count":22,"title":["Using the Accelerometers Integrated in Smartphones to Evaluate Essential Tremor"],"prefix":"10.1159","volume":"93","author":[{"given":"Suhan","family":"Senova","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Damien","family":"Querlioz","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Claire","family":"Thiriez","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pierre","family":"Jedynak","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"B\u00e9chir","family":"Jarraya","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"St\u00e9phane","family":"Palfi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2015,2,18]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1097\/00002826-200109000-00004"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.1109\/86.650297"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1109\/10.661163"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1016\/0013-4694(89)90179-X"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.1002\/1531-8257(200101)16:1<47::AID-MDS1012>3.0.CO;2-V"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.1002\/mds.870131314"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.1016\/S0987-7053(02)00296-4"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.1109\/TBME.2006.886670"},{"key":"ref9","doi-asserted-by":"publisher","DOI":"10.1016\/0165-0270(90)90140-B"},{"key":"ref10","doi-asserted-by":"publisher","DOI":"10.1002\/mds.10473"},{"key":"ref11","doi-asserted-by":"publisher","DOI":"10.1016\/S1353-8020(99)00052-8"},{"key":"ref12","doi-asserted-by":"publisher","DOI":"10.1002\/mds.870060411"},{"key":"ref13","doi-asserted-by":"publisher","DOI":"10.1159\/000110159"},{"key":"ref14","doi-asserted-by":"publisher","DOI":"10.1002\/mds.870090114"},{"key":"ref15","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0014669"},{"key":"ref16","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0024974"},{"key":"ref17","doi-asserted-by":"publisher","DOI":"10.1002\/mds.24923"},{"key":"ref18","doi-asserted-by":"publisher","DOI":"10.1093\/brain\/awl190"},{"key":"ref19","doi-asserted-by":"publisher","DOI":"10.1002\/9780470317082"},{"key":"ref20","doi-asserted-by":"publisher","DOI":"10.1148\/radiology.148.3.6878708"},{"key":"ref21","doi-asserted-by":"publisher","DOI":"10.1002\/mds.870110113"},{"key":"ref22","doi-asserted-by":"publisher","DOI":"10.1002\/1531-8257(199903)14:2<288::AID-MDS1014>3.0.CO;2-M"},{"key":"ref23","doi-asserted-by":"publisher","DOI":"10.1002\/mds.23201"},{"key":"ref24","doi-asserted-by":"publisher","DOI":"10.1002\/mds.22445"},{"key":"ref25","doi-asserted-by":"publisher","DOI":"10.1109\/IEMBS.2010.5627240"},{"key":"ref26","doi-asserted-by":"publisher","DOI":"10.1109\/IEMBS.2011.6091296"},{"key":"ref27","doi-asserted-by":"publisher","DOI":"10.1016\/j.parkreldis.2011.01.001"},{"key":"ref28","doi-asserted-by":"publisher","DOI":"10.3389\/fnhum.2012.00357"}],"container-title":["Stereotactic and Functional Neurosurgery"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/369354","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/369354","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,23]],"date-time":"2025-04-23T18:01:01Z","timestamp":1745431261000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000369354"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2015]]},"references-count":28,"journal-issue":{"issue":"2","published-online":{"date-parts":[[2015,3,1]]},"published-print":{"date-parts":[[2015,3,19]]}},"URL":"https:\/\/doi.org\/10.1159\/000369354","archive":["Portico"],"relation":{},"ISSN":["1011-6125","1423-0372"],"issn-type":[{"type":"print","value":"1011-6125"},{"type":"electronic","value":"1423-0372"}],"subject":[],"published":{"date-parts":[[2015]]}}}
