本論文使用智慧型手機和其內建的陀螺儀開發一套復健動作監控系統。主要功能如下：(1)判斷病患復健動作狀況（如正確與錯誤動作、動作次數）；(2)語音提示及螢幕顯示相關資訊達到即時回饋；(3)隨時隨地能透過網路連線上傳復健資訊置資料庫，或更新處方箋；(4)治療師使用資料庫監控病患狀況並設定參數達到遠端更新處方功能。
關於手機陀螺儀在量測動作角度之準確度方面，馬達驗證部分在三種轉速下（20.8°/s、60.9°/s與112.1°/s），三個軸向的平均誤差分別為0.1°±0.2°、0.4°±0.1°與0.3°±0.1°，皆在1°以內；人體動作驗證與光學立體攝影系統作比較，髖關節屈曲、膝關節伸直及走路主要平面誤差在6°以內。另外，本系統能夠即時判斷復健動作正確與否，可協助病患確保動作正確性，避免錯誤動作造成二次傷害。

In this thesis, we developed a remote rehabilitation movement monitoring system based on the smartphone and its built-in gyroscope. The main functions of this system are as follows, (1) to assess patient’s movement status (such as correct or wrong movement and number of movements). (2) Voice guidance and information display on the screen for real-time feedback. (3) To upload and download data from database via wireless network. (4) The therapist can assess the status of patient via database and update the parameter of prescription.
The accuracy of the angle measurement of smartphone and the built-in gyroscope was verified in the experiments of motor movement. The mean error were 0.1°±0.2°, 0.4°±0.1° and 0.3°±0.1° at the angular velocity 20.8°/s, 60.9°/s and 112.1°/s separately. In human motion experiment, the mean errors are less than 6° at hip flexion, knee extension and walking by comparing with a 3D stereophotographic system. In addition, this system can assess rehabilitation movement in real time to help patients to ensure correct movement and avoid damage again.
