碩士 === 義守大學 === 電機工程學系 === 104 === Human leg is composed of femur (thigh bone), knee joint, tibia (shin bone), ankle joint and foot, etc. As one of the most vulnerable body joints, knee joint needs seamless rehabilitation after surgery therapy. People are highly concern about the curative effects while the rehabilitation plan is in progress. In this thesis, a low-cost auxiliary device which can record the knee joint movement and evaluate the situation for postoperative rehabilitation is developed. This auxiliary device is the integration of an embedded system (ARM Cortex-A9 and Xilinx Zynq-7010), a three-axis gyroscope (STMicroelectronics L3G4200D) and a three-axis accelerometer (Analog Devices ADXL345) and with an USB (Universal Serial Bus) interface for further communication or application. In order to verify the effectiveness of the auxiliary device, eight rehabilitation scenarios and three assessment categories have been identified and illustrated. The detailed depictions of knee joint movement for all three assessment categories at each rehabilitation scenario are also provided.
