摘要: | 隨著臺灣將邁入超高齡社會,年長者能維持自主獨立生活的能力是很重要的議題,而日常生活中最基本且重要的動作為坐到站(Sit-to-Stand, STS),並可將其視為判斷自主活動能力獨立性之重要指標,現今已知STS透過訓練能提升其能力,且於居家進行自我檢測具有臨床意義。本實驗室為了提升年長者起身活動的能力,長期致力於開發坐到站起身輔助裝置,本研究承接過往實驗室之研究基礎,所開發之系統以體積小 (16 cm×13 cm×1.5 cm)、重量輕 (313 g)與低功耗 (靜態電流為2.74 mA)作為設計考量,完成一套穿戴式多通道肌電訊號量測裝置,同時量測並量化STS主要所使用肌肉(脛前肌、內側股四頭肌、豎脊肌)之肌力,用於評估主要肌群發力是否適當,可透過日常監測方式長期進行肌力追蹤,亦可評估左右腳肌力是否不對稱,藉此制定個人化訓練或是合適的復健療程,以降低肌肉老化速度。本研究之系統設計可分為硬體電路與軟硬體整合之使用者介面兩部分,前者包括多工器與解多工器的使用、放大器與高低通濾波器的放大倍率及頻帶設計、類比開關與積分器的控制與設置,以及各類元件之選擇考量於本文皆有詳細闡述;而後者包含系統控制以及利用MATLAB設計一簡單好上手之使用者介面,為了能更降低使用的學習難度,亦可透過文字、圖像與聲音等方式做動作指令之提醒,藉此提供使用者完善、便利且視覺化的使用體驗,期望未來能與物聯網與手機端連動,同步搭配其他生理訊息,令使用者能更深入了解身體健康資訊。 As Taiwan transitions into a super aged society, maintaining the ability of the elderly to lead independent lives is an important issue. One of the most fundamental and essential movements is the Sit-to-Stand (STS) action, which can be considered a crucial indicator for assessing independence in daily life. Currently, it is known that STS training can enhance one’s STS capability, and self-testing of STS performance at home has clinical significance. Our laboratory has long been dedicated to enhancing the mobility of the elderly by developing a STS assistance device for a long time. Building upon previous researches, this study introduces a wearable multi-channel electromyography (EMG) measurement device, designed with compact size (16 cm×13 cm×1.5 cm), lightweight (313 g), and low power consumption (quiescent current is 2.74 mA). It measures quantitatively the strength of the key muscles (tibialis anterior, quadriceps vastus medialis, erector spinae) primarily used in the STS task, aiming to assess the appropriateness of force exerted by the major muscle groups. This information aids in formulating personalized training or suitable rehabilitation programs, reducing the pace of muscle atrophy for elderly. In this study, the system design includes hardware circuits and a user interface for its operation. The former involves the use of multiplexers and demultiplexers, amplifiers, high and low-pass filters, analog switches, and integrators, with detailed design considerations. The user interface includes system control and a user-friendly interface designed with the MATLAB environment. To enhance user accessibility, action prompts are provided through text, images, and sound, offering a comprehensive, convenient, and visual user experience. In the future, we plan to connect the system with the Internet of Things (IoT) and mobile applications, synchronizing with other physiological signals to provide users with a deeper understanding of their health condition. |
