Problems solved by technology
[0012] The purpose of the present invention is to provide a gait detection system based on plantar pressure, which aims to solve the problem that the existing multi-methods of gait detection based on image processing have low precision and cannot detect three-dimensionally. Although the detection by an electric signal sensor has high precision , but there is no question about the corresponding relationship between the plantar pressure and the change of the ankle joint angle

The invention discloses a gait detection system based on sole pressure. The gait detection system comprises an ankle angle detection system, a sole pressure detection system and a gait detection system. The ankle angle detection system comprises a motion sensor, a data acquisition system and an upper computer. The data acquisition system acquires and transmits data of the motion sensor to the upper computer. The sole pressure detection system comprises a dynamometer insole, an AD acquisition module and an upper computer. The dynamometer insole is provided with a thin film pressure sensor. The gait detection system comprises a communication module, a data acquisition module, a Kalman filter module, a space attitude judgment module and a data display module. According to the system, the spatial posture of the ankle is judged in real time through judgment on the sole pressure change situation, the gait situation of a person to be tested is further analyzed, and the requirements of a novel auxiliary ankle rehabilitative robot system subjectively controlled by a patient can be further met.
Description
technical field [0001] The invention belongs to the field of sensor detection, in particular to a gait detection system based on plantar pressure. Background technique [0002] In the rehabilitation process of hemiplegic patients, early rehabilitation training of the ankle joint is very important, because it affects whether the patient can return to normal gait in the future. A person's central nervous system is damaged after a stroke, which causes the neurons around the damaged central area to die and form a penumbra. In the recovery process of stroke patients in the first two months, the penumbra plays a vital role in the recovery of the nervous system, which means that whether early stroke patients can recover depends largely on the penumbra. recover. Many scholars have been using positron emission tomography to study it. According to the content of neurodevelopmental technology, people can use some specific methods to induce hemiplegic patients to gradually feel the s...
