Embodiment Construction

[0021] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0022] According to an embodiment of the present invention, such as figure 1 Shown is the overall structure schematic diagram of this invention. patient put on figure 2 In the shown shoe, there is an insole (2) for placing a pressure sensor (4) inside the shoe, and the sensor is connected to the signal acquisition and transmission module (5). The signal acquisition and transmission module mainly includes a microcontroller C8051F410, a multi-channel signal selection switch ADG1608, an operational amplifier OPA340, a Bluetooth module HC06, a voltage converter REG1117 and peripheral resistors and capacitors. The main function of the microcontroller is to control the acquisition, encoding and transmission of the entire signal; the function of the multi-channel signal selection switch is to select the signals of the two channels to ensure that the...

Abstract

The invention provides a plantar pressure measurement based wearable real-time monitoring and feedback alarm device and method for scissors gaits. The device mainly comprises a sole provided with pressure sensors, a signal acquisition and transmission module and a portable data receiving and processing terminal. The sensors are fixed on the sole, the signal acquisition and transmission module and a power supply battery are placed at the position of a heel, and the device is wearable. The signal acquisition and transmission module sends acquired signals to the portable data processing terminal (a smart phone, a tablet personal computer and the like) in a wireless transmission mode. The data processing terminal processes the received plantar pressure signals in real time and displays the plantar pressure signals in a waveform mode. The detection method for the scissors gaits includes the steps of firstly, dividing gait periods according to signal features to find a time division point between two adjacent gait periods, which is the forefoot raising moment; secondly, calculating the dynamic pressure index (heel bearing ratio) in each gait period; and finally, comparing the dynamic pressure indexes with a set threshold, if the dynamic pressure indexes are smaller than the threshold, judging that the current gaits are scissors gaits, sending alarm signals such as sound and vibration to remind patients to correct the gaits. Meanwhile, the acquired plantar pressure data can be stored automatically and sent to doctors, parents and the like as evaluation evidences of recovery progress and references for formulation of the next recovery training.

Description

technical field [0001] The invention relates to a device and method for real-time monitoring, feedback and alarm of wearable pointed foot gait. More specifically, it relates to a wearable pointed foot gait real-time monitoring feedback alarm device and method based on plantar pressure measurement. Background technique [0002] Pointed feet are a very common abnormal gait in patients with spastic cerebral palsy. The main manifestations are that the toes are always on the ground during standing and walking, and the heel is not fully or even not on the ground. Pointed gait can lead to poor walking stability, prone to falls, and also affects the development of the heel to a certain extent. Long-term effective walking training is very important for the improvement of pointed foot gait. During the walking training process, the device monitors the gait in real time, and once an abnormal gait occurs, it sends out a sound feedback signal to remind the patient to correct the gait, t...
