步態分析是復健計畫的基礎，對於中風病患而言，下肢活動影響行動的能力，直接影響對社會功能的參與。本計畫旨在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；原規劃兩年期研究，目前提出第二年。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，包括開發及驗證(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前年(105年)底栓塞型中風，在之後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 a 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. Currently this proposal summarizes a preliminary result and draws the tasks performed in the second year. In the study two issues will be explored; first, both (i) the meaningful data screening of IMUs, and (ii) kinesiology parameters 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 of 2016. During the subsequent 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.
