During the last few years, many studies have been carried out to assess spasticity using wearable IMU (inertial measurements unit) sensors. This review aims to provide an updated framework of the current research on IMUs wearable sensors in people living with spasticity in recent studies published between 2017 and 2021. A total of 322 articles were screened, then finally 10 articles were selected. Results show the lack of homogenization of study procedures and missing apparatus information in some studies. Still, most studies performed adequately on measures of reporting and found that IMUs wearable data was successful in their respective purposes and goals. As IMUs estimate translational and rotational body motions, we believe there is a strong potential for these applications to estimate velocity-dependent exaggeration of stretch reflexes and spasticity-related characteristics in spasticity. This review also proposes new directions of research that should be challenged by larger study groups and could be of interest to both researchers as well as clinicians. The use of IMUs to evaluate spasticity is a promising avenue to provide an objective measurement as compared to non-instrumented traditional assessments.<\/jats:p>","DOI":"10.3390\/s22051791","type":"journal-article","created":{"date-parts":[[2022,2,24]],"date-time":"2022-02-24T21:11:07Z","timestamp":1645737067000},"page":"1791","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":27,"title":["Recent State of Wearable IMU Sensors Use in People Living with Spasticity: A Systematic Review"],"prefix":"10.3390","volume":"22","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9736-8300","authenticated-orcid":false,"given":"Yehuda","family":"Weizman","sequence":"first","affiliation":[{"name":"Department of Health and Medical Sciences, School of Health Sciences, Hawthorn Campus, Swinburne University of Technology, Melbourne 3122, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2281-6399","authenticated-orcid":false,"given":"Oren","family":"Tirosh","sequence":"additional","affiliation":[{"name":"Department of Health and Medical Sciences, School of Health Sciences, Hawthorn Campus, Swinburne University of Technology, Melbourne 3122, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Franz Konstantin","family":"Fuss","sequence":"additional","affiliation":[{"name":"Chair of Biomechanics, Faculty of Engineering Science, University of Bayreuth, D-95440 Bayreuth, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Adin Ming","family":"Tan","sequence":"additional","affiliation":[{"name":"Department of Health and Medical Sciences, School of Health Sciences, Hawthorn Campus, Swinburne University of Technology, Melbourne 3122, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2292-0946","authenticated-orcid":false,"given":"Erich","family":"Rutz","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics, The Royal Children\u2019s Hospital, Melbourne 3052, Australia"},{"name":"Murdoch Children\u2019s Research Institute, MCRI, Parkville, Melbourne 3052, Australia"},{"name":"Department of Paediatrics, The University of Melbourne, Melbourne 3052, Australia"},{"name":"Medical Faculty, University of Basel, 4001 Basel, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,2,24]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"725","DOI":"10.1016\/S1474-4422(07)70193-X","article-title":"Spastic movement disorder: Impaired reflex function and altered muscle mechanics","volume":"6","author":"Dietz","year":"2007","journal-title":"Lancet Neurol."},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"708","DOI":"10.1038\/sj.sc.3101928","article-title":"Spasticity-assessment: A review","volume":"44","author":"Nielsen","year":"2006","journal-title":"Spinal Cord."},{"key":"ref_3","doi-asserted-by":"crossref","first-page":"66","DOI":"10.1177\/0888439002250449","article-title":"Spasticity in multiple sclerosis","volume":"17","author":"Barnes","year":"2003","journal-title":"Neurorehabilit.
