In this article, we propose a novel computation framework to recognize gait patterns in patients with PD. The key idea of our approach is to distinguish gait patterns in PD patients from healthy individuals by accurately extracting gait features that capture all three aspects of movement functions, that is, stability, symmetry, and harmony. The proposed framework contains three steps: gait phase discrimination, feature extraction and selection, and pattern classification. In the first step, we put forward a sliding window--based method to discriminate four gait phases from plantar pressure data. Based on the gait phases, we extract and select gait features that characterize stability, symmetry, and harmony of movement functions. Finally, we recognize PD gait patterns by applying a hybrid classification model. We evaluate the framework using an open dataset that contains real plantar pressure data of 93 PD patients and 72 healthy individuals. Experimental results demonstrate that our framework significantly outperforms the four baseline approaches.<\/jats:p>","DOI":"10.1145\/2890511","type":"journal-article","created":{"date-parts":[[2016,8,26]],"date-time":"2016-08-26T12:25:39Z","timestamp":1472214339000},"page":"1-22","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":10,"title":["Recognizing Parkinsonian Gait Pattern by Exploiting Fine-Grained Movement Function Features"],"prefix":"10.1145","volume":"8","author":[{"given":"Tianben","family":"Wang","sequence":"first","affiliation":[{"name":"School of Computer Science, Northwestern Polytechnical University, Xi'an Shaanxi, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhu","family":"Wang","sequence":"additional","affiliation":[{"name":"School of Computer Science, Northwestern Polytechnical University, Xi'an Shaanxi, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Daqing","family":"Zhang","sequence":"additional","affiliation":[{"name":"Institut Mines-T\u00e9l\u00e9com\/T\u00e9l\u00e9com SudParis, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tao","family":"Gu","sequence":"additional","affiliation":[{"name":"RMIT University, Melbourne VIC, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hongbo","family":"Ni","sequence":"additional","affiliation":[{"name":"School of Computer Science, Northwestern Polytechnical University, Xi'an Shaanxi, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jiangbo","family":"Jia","sequence":"additional","affiliation":[{"name":"School of Computer Science, Northwestern Polytechnical University, Xi'an Shaanxi, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xingshe","family":"Zhou","sequence":"additional","affiliation":[{"name":"School of Computer Science, Northwestern Polytechnical University, Xi'an Shaanxi, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jing","family":"Lv","sequence":"additional","affiliation":[{"name":"Zhuhai Kingsoft Office Software Co., Ltd, Zhuhai Guangdong, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"320","published-online":{"date-parts":[[2016,8,23]]},"reference":[{"key":"e_1_2_1_1_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1460-9568.2006.05033.x"},{"key":"e_1_2_1_2_1","doi-asserted-by":"publisher","DOI":"10.1097\/00007632-198403000-00016"},{"key":"e_1_2_1_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0031-3203(96)00142-2"},{"key":"e_1_2_1_4_1","doi-asserted-by":"publisher","DOI":"10.7547\/0990512"},{"key":"e_1_2_1_5_1","doi-asserted-by":"publisher","DOI":"10.1186\/1743-0003-2-3"},{"volume-title":"International Conference on Biomedical Engineering 354--359","author":"Gandomkar Z.","key":"e_1_2_1_6_1"},{"key":"e_1_2_1_7_1","first-page":"3","article-title":"Parkinson's disease in India: An analysis of publications output during 2002--2011.
