Current evaluation tools in DCP are subjective and time-consuming. Sensors could yield objective information on pathological patterns in DCP, but their reliability has not yet been evaluated. The objectives of this study were to evaluate (i) reliability and (ii) discriminative ability of sensor parameters. Methods\u2014Inertial measurement units were placed on the arm, forearm, and hand of individuals with and without DCP while performing reach-forward, reach-and-grasp-vertical, and reach-sideways tasks. Intra-class correlation coefficients (ICC) were calculated for reliability, and Mann\u2013Whitney U-tests for between-group differences. Results\u2014Twenty-two extremities of individuals with DCP (mean age 16.7 y) and twenty individuals without DCP (mean age 17.2 y) were evaluated. ICC values for all sensor parameters except jerk and sample entropy ranged from 0.50 to 0.98 during reach forwards\/sideways and from 0.40 to 0.95 during reach-and-grasp vertical. Jerk and maximal acceleration\/angular velocity were significantly higher for the DCP group in comparison with peers. Conclusions\u2014This study was the first to assess the reliability of sensor parameters in individuals with DCP, reporting high between- and within-session reliability for the majority of the sensor parameters. These findings suggest that pathological movements of individuals with DCP can be reliably captured using a selection of sensor parameters.<\/jats:p>","DOI":"10.3390\/s23031574","type":"journal-article","created":{"date-parts":[[2023,2,1]],"date-time":"2023-02-01T02:06:44Z","timestamp":1675217204000},"page":"1574","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Reliability and Discriminative Validity of Wearable Sensors for the Quantification of Upper Limb Movement Disorders in Individuals with Dyskinetic Cerebral Palsy"],"prefix":"10.3390","volume":"23","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8695-0095","authenticated-orcid":false,"given":"Inti","family":"Vanmechelen","sequence":"first","affiliation":[{"name":"Research Group for Neurorehabilitation (eNRGy), Department of Rehabilitation Sciences, KU Leuven, 8200 Bruges, Belgium"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5232-0434","authenticated-orcid":false,"given":"Saranda","family":"Bekteshi","sequence":"additional","affiliation":[{"name":"Research Group for Neurorehabilitation (eNRGy), Department of Rehabilitation Sciences, KU Leuven, 8200 Bruges, Belgium"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9307-4102","authenticated-orcid":false,"given":"Helga","family":"Haberfehlner","sequence":"additional","affiliation":[{"name":"Research Group for Neurorehabilitation (eNRGy), Department of Rehabilitation Sciences, KU Leuven, 8200 Bruges, Belgium"},{"name":"Department of Rehabilitation Medicine, Amsterdam Movement Sciences, Amsterdam UMC, 1081 HZ Amsterdam, The Netherlands"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hilde","family":"Feys","sequence":"additional","affiliation":[{"name":"Research Group for Neurorehabilitation (eNRGy), Department of Rehabilitation Sciences, KU Leuven, 3000 Leuven, Belgium"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kaat","family":"Desloovere","sequence":"additional","affiliation":[{"name":"Research Group for Neurorehabilitation (eNRGy), Department of Rehabilitation Sciences, KU Leuven, 3212 Pellenberg, Belgium"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5548-9163","authenticated-orcid":false,"given":"Jean-Marie","family":"Aerts","sequence":"additional","affiliation":[{"name":"Department of Biosystems, Measure, Model & Manage Bioresponses (M3-BIORES), Division of Animal and Human Health Engineering, KU Leuven, 3000 Leuven, Belgium"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Elegast","family":"Monbaliu","sequence":"additional","affiliation":[{"name":"Research Group for Neurorehabilitation (eNRGy), Department of Rehabilitation Sciences, KU Leuven, 8200 Bruges, Belgium"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,2,1]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"741","DOI":"10.1016\/S1474-4422(17)30252-1","article-title":"Clinical presentation and management of dyskinetic cerebral palsy","volume":"16","author":"Monbaliu","year":"2017","journal-title":"Lancet Neurol."},{"key":"ref_2","first-page":"8","article-title":"A report: The definition and classification of cerebral palsy April 2006","volume":"109","author":"Rosenbaum","year":"2007","journal-title":"Dev.
