Method for measuring planta pressure for rehabilitation therapy

Abstract

The invention relates to a method for measuring planta pressure for rehabilitation therapy. The method is characterized in that thin film piezoresistive type pressure sensors are adopted to be placed on planta pressure points in left and right sock linings, each sock lining is of a three layer structure, and the top layer and the bottom layer are fiber layers; the thin film piezoresistive type pressure sensors are tightly adhered to and fixed on the bottom layers closely, are fixedly connected with the fibers at the top layers through soft salient points, and transmits the acquired resistance signals corresponding to the pressure to two signal processing transmitters which are corresponding to the pressure sensors of the left and right sock linings, the resistance signals are subjected to resistance-voltage conversion and wave filtration and then are output to two corresponding micro processors so as to be subjected to AD (analog-to-digital) conversion respectively; data acquired from two feet are merged into a data packet and is transmitted to a receiver; the receiver transmits the data of the left and right feet to a PC (personal computer) through a USB (universal serial bus); and the PC reads the data through the triggering of a timing device, and unpacks the data packet, and signal processing and three dimensional display are carried out through software.

Description

technical field [0001] The present invention relates to a rehabilitation diagnosis and treatment instrument, in particular to a plantar pressure measurement method for rehabilitation treatment, which is mainly applicable to the disease assessment in the early stage of rehabilitation treatment for patients with weakened or lost walking ability, and provides a basis for formulating rehabilitation training plans, Evaluation of the effect during or after rehabilitation training and early detection of diabetes. Background technique [0002] Due to changes in the living environment and people's eating habits, the incidence of cardiovascular and cerebrovascular diseases such as stroke (commonly known as apoplexy) is very high. Although the mortality rate of apoplexy has decreased with the improvement of current medical technology, those who survive Among the patients, about 70% still have different degrees of limb motor dysfunction such as hemiplegia, and 30% of them can only be ac...

Problems solved by technology

[0003] The traditional gait measuring instrument adopts the arrangement of rigid sensor arrays on the soles of the feet, which requires thousands of pressure sensors, resulting in a large amount of data, resulting in low sampling rate, high price, narrow use area, poor flexibility, and poor comfort; The signal transmission mode between the measuring instrument and the PC display, one is the transmission mode of the physical cable, and the other is to save the data of the patient during the test in the memory. After the test is completed, the PC reads it from the memory again. Take the patient's gait data

The former uses physical cables to restrain the freedom of the patient and seriously interferes with the individual being tested, so the measured data is also inaccurate. Although the latter solves the problem of interference to the patient, it cannot observe the patient's gait in real time. The display can only simply display the waveform curve of the regular gait, which is not conducive to rehabilitation doctors and diagnostic doctors to understand and analyze the patient's state in detail
