碩士 === 國立臺灣科技大學 === 電子工程系 === 101 === 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.
