A crucial factor to ensure the effectiveness of game-based rehabilitation systems is to assess the correctness of the movements performed by the patient during the game-playing sessions. In this study, we propose a game-based rehabilitation system for upper-limb cerebral palsy that includes three game-based exercises and a computerized assessment method. The game-based exercises aim to engage the participant in shoulder flexion, shoulder horizontal abduction\/adduction, and shoulder adduction physical exercises that target the right arm. Human interaction with the game-based rehabilitation system is achieved using a Kinect sensor that tracks the skeleton joints of the participant. The computerized assessment method aims to assess the correctness of the right arm movements during each game-playing session by analyzing the tracking data acquired by the Kinect sensor. To evaluate the performance of the computerized assessment method, two groups of participants volunteered to participate in the game-based exercises. The first group included six cerebral palsy children and the second group included twenty typically developing subjects. For every participant, the computerized assessment method was employed to assess the correctness of the right arm movements in each game-playing session and these computer-based assessments were compared with matching gold standard evaluations provided by an experienced physiotherapist. The results reported in this study suggest the feasibility of employing the computerized assessment method to evaluate the correctness of the right arm movements during the game-playing sessions.<\/jats:p>","DOI":"10.3390\/s20082416","type":"journal-article","created":{"date-parts":[[2020,4,24]],"date-time":"2020-04-24T11:42:14Z","timestamp":1587728534000},"page":"2416","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":26,"title":["A Game-Based Rehabilitation System for Upper-Limb Cerebral Palsy: A Feasibility Study"],"prefix":"10.3390","volume":"20","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9399-5769","authenticated-orcid":false,"given":"Mohammad I.","family":"Daoud","sequence":"first","affiliation":[{"name":"Department of Computer Engineering, German Jordanian University, Amman 11180, Jordan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7806-1108","authenticated-orcid":false,"given":"Abdullah","family":"Alhusseini","sequence":"additional","affiliation":[{"name":"Department of Computer Engineering, German Jordanian University, Amman 11180, Jordan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3030-848X","authenticated-orcid":false,"given":"Mostafa Z.","family":"Ali","sequence":"additional","affiliation":[{"name":"Department of Computer Information Systems, Jordan University of Science and Technology, Irbid 22110, Jordan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1296-0231","authenticated-orcid":false,"given":"Rami","family":"Alazrai","sequence":"additional","affiliation":[{"name":"Department of Computer Engineering, German Jordanian University, Amman 11180, Jordan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2020,4,24]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"8","DOI":"10.1111\/j.1469-8749.2007.tb12610.x","article-title":"A report: The Definition and classification of cerebral palsy April 2006","volume":"49","author":"Rosenbaum","year":"2007","journal-title":"Dev.
