步態分析是復健計畫的基礎，對於中風病患而言，下肢的活動影響行動的能力，對社會功能的參與有重大的影響。此兩年期計畫，建立慣性感測器應用於中風病患下肢運動學之步態資料分析、與臨床主觀量表間的關聯性。研究分為兩部分— (1)下肢步態參數分析、及穿戴裝置IMU數據篩選演算法，其中開發及驗證(i)感測數據前處理及篩選機制演算法、及(ii)特徵參數提取及關節動作演算法 等；(2)復健工程臨床實務，其中包含(i)無線慣性感測系統(四個慣性感測器)建置、(ii)主觀量表及收案數據客觀特徵關聯性分析、(iii)中風患者下肢步態特徵和平衡行走及日常生活能力客觀評估 等。此計畫發想，肇因於申請人家母於106年底栓塞型中風，在六個月復健期間隔月來回於汐止國泰醫院(韓紹禮主治醫師為本計畫共同主持人)及羅東博愛醫院間，對於提昇中風患者行走及生活能力客觀評估可靠性、以及後續居家復健而有遠距復健導致穿戴裝置訊號有效性課題，而引發此一研究規劃。 ;The gate analysis plays the basis of rehabilitation plan. For the stroke patients with hemiparetic or hemiplegia, their lower-limb movement ability decides how well they can join the social activities. This two-year research project aims to investigate the parameter extraction of gate analysis for lower-limb kinesiology through using inertial measurement units (IMUs); further, the correlation between the developed techniques and the clinical subjective assessment is to be investigated. Two issues are explore; first, both (i) the meaningful data screening of IMUs, and (ii) kinesiology parameter computation of lower-limb movement are coded and justified; second, the rehabilitation engineering practice is considered including (i) the construction of wireless four-IMUs measurement module, (ii) the correlation analysis between subjective assessment and objective extracted parameters of gait analysis, and (iii) the objective evaluation to the patients’ daily activity from their lower-limb gait parameters. This research project was initiated by the thrombotic stroke of PI’s mother in December, 2016. During the period of the six-month rehabilitation treatment between Sijhih Cathay General Hospital (Dr. Han as the Co-PI of this project) and Lotung Poh-Ai Hospital. The issues on enhancing the reliability of objectively assessing stroke patients’ walking ability and daily-life capability, and on acquiring meaningful data of wearable instrument from remote in-house rehab treatment both ignite the ideas of this study.
