One feature of VR systems that is essential for use in clinical evaluation and to warrant presence is the lack of behavioral distortion from real-world execution. Herein, we present a technical description of our VR and its validation to evaluate rhythmic motor patterns when experimental subjects perform a finger tapping test. Execution of the test was performed at different rates in the VR system, and compared to the gold-standard real-world testing. The VR system proved to be as valid and reliable as real-world testing to characterize arrythmokinetic profiles present in Parkinsonian and elderly subjects (compared to young subjects), at the different rates of execution. VR served as a complementary tool in a research setting to isolate subjects from unnaturalistic environments during clinical evaluation, such as labrooms or brain scans, since it did not bias behavior from real-world evaluation in a basic clinical test.<\/jats:p>","DOI":"10.1162\/pres_a_00159","type":"journal-article","created":{"date-parts":[[2014,4,30]],"date-time":"2014-04-30T14:24:41Z","timestamp":1398867881000},"page":"291-307","source":"Crossref","is-referenced-by-count":0,"title":["Low-Cost Virtual Reality System in Evaluation of Rhythmic Motor Patterns in Elderly and Parkinson's Disease Patients"],"prefix":"10.1162","volume":"22","author":[{"given":"Gabriel","family":"Sanmart\u00edn","sequence":"first","affiliation":[{"name":"Computer Graphics and Data Engineering Group (COGRADE), CITIUS, University of Santiago de Compostela"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Juli\u00e1n","family":"Flores","sequence":"additional","affiliation":[{"name":"Computer Graphics and Data Engineering Group (COGRADE), CITIUS, University of Santiago de Compostela"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ver\u00f3nica","family":"Robles-Garc\u00eda","sequence":"additional","affiliation":[{"name":"NEUROcom Neuroscience and Motor Control Group Dept. of Medicine\u2014INEF\u2014INIBIC Universidade da Coru\u00f1a Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pablo","family":"Arias","sequence":"additional","affiliation":[{"name":"NEUROcom Neuroscience and Motor Control Group Dept. of Medicine\u2014INEF\u2014INIBIC Universidade da Coru\u00f1a Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Javier","family":"Cudeiro","sequence":"additional","affiliation":[{"name":"NEUROcom Neuroscience and Motor Control Group Dept. of Medicine\u2014INEF\u2014INIBIC Universidade da Coru\u00f1a Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"281","reference":[{"key":"p_3","doi-asserted-by":"publisher","DOI":"10.1007\/s00221-007-1263-y"},{"key":"p_4","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0009675"},{"key":"p_5","doi-asserted-by":"publisher","DOI":"10.1016\/j.clinph.2012.04.001"},{"key":"p_6","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0030021"},{"key":"p_7","doi-asserted-by":"publisher","DOI":"10.1007\/s00221-005-0272-y"},{"key":"p_8","volume":"10","author":"Biocca F.","year":"1997","journal-title":"Journal of Computer-Mediated Communication, 3(2). doi"},{"key":"p_9","doi-asserted-by":"publisher","DOI":"10.1016\/j.parkreldis.2012.03.004"},{"key":"p_10","doi-asserted-by":"publisher","DOI":"10.1002\/1531-8257(200001)15:1<36::AID-MDS1008>3.0.CO;2-M"},{"key":"p_11","doi-asserted-by":"publisher","DOI":"10.1212\/WNL.45.2.386"},{"issue":"48","key":"p_12","first-page":"1","volume":"7","author":"Cameirao M.","year":"2010","journal-title":"Journal of NeuroEngineering and Rehabilitation"},{"key":"p_14","doi-asserted-by":"publisher","DOI":"10.1002\/1531-8257(199901)14:1<63::AID-MDS1012>3.0.CO;2-V"},{"key":"p_15","doi-asserted-by":"publisher","DOI":"10.1093\/brain\/118.4.935"},{"key":"p_16","doi-asserted-by":"publisher","DOI":"10.1016\/j.neulet.2011.05.010"},{"key":"p_17","doi-asserted-by":"publisher","DOI":"10.1002\/ana.410410614"},{"key":"p_18","doi-asserted-by":"publisher","DOI":"10.1109\/VR.1999.756955"},{"key":"p_19","doi-asserted-by":"publisher","DOI":"10.1682\/JRRD.2009.10.0165"},{"key":"p_20","doi-asserted-by":"publisher","DOI":"10.1016\/0022-3956(75)90026-6"},{"key":"p_21","doi-asserted-by":"publisher","DOI":"10.1002\/mds.870130310"},{"key":"p_22","doi-asserted-by":"publisher","DOI":"10.1007\/s00221-002-1354-8"},{"key":"p_23","doi-asserted-by":"publisher","DOI":"10.1016\/j.cogbrainres.2004.05.008"},{"key":"p_24","first-page":"624","author":"Holden M.
