碩士 === 國立臺北科技大學 === 機電整合研究所 === 102 === PD patients often have motionless tremor, freezing of gait, gait instability problems and so on, which are prone to affect the function of daily life. When freezing of gait occurs on PD patients, how to immediately help patients to remind themselves to walk again is the research project of this thesis, and the main goal is to develop a kneepad style laser reminding device for PD patients to assist walking. In markets there has been some products designed for walking stick combined with visual reminding, but most PD patients do not need to use walking sticks as walking helper and additionally that pace distance of the visual reminding products is fixed, as a result in this research we consider the convenience, portability and adaptability and then do research to design the laser device which can combine with kneepads. We utilize visual reminding and adjustable pace distance to develop and design the device and this device can effectively give reminding immediately and give assistance when PD patients are in need. This device utilize switch of sole, single chip, and accelerator to control communication and adjudgement. When PD patients are in need, through the conveyance of switch of sole to single chip of kneepad laser device followed by shooting laser beam in front of the feet of PD patients to remind them cross over this laser beam and allow PD patients to walk forward smoothly, it can also through the stepper motor to control the light head of laser and adjust the pace distance in demand. Additionally, this research utilize accelerators combined with switches of sole to calculate pace distance and detect the FOG, and immediately convey the walking distance and frequency to computer by blue-tooth to see and adjudge that pace situation.
