Abstract

A body balance detecting instrument which is based on the gesture tracing technology and evaluates the balance and the stability of a testee by measuring the pressured applied by the testee on a platform comprises a force measuring platform and a miniature computer and is characterized in that the force measuring platform is connected with the miniature computer through a data wire. The force measuring platform mainly comprises four balance plates and also comprises a handrail for safety consideration, a platform for adjusting the horizontal state and a data wire interface for performing data transmission and reception. A gesture tracing measuring sensor is arranged below the feet of the testee so as to measure the pressure suffered by the platform. The four balance plates evaluate and measure the fluctuation and change of the suffered pressure and obtain the comprehensive body balance index. Different parts of the feet of the testee generate different pressures due to movement of the body so that the balanced capability of the testee can be evaluated.

Description

The body balance detector

Technical field

This utility model relates to electrical category, refers to a kind ofly based on the posturography technology especially, estimates measured's the balance and the instrument or the system of stability by measuring the pressure that the measured is applied on the platform.

Background technology

The raising of life expected value and the development of current medical science and technology, making more old people, more independently life more positive than in the past, prevention fracture becomes most important publilc health concern topic.The measurement index of falling is designed to assess the individual risk of falling, this problem is relevant with balancing a survey, risk can cause serious The Long-term Effect to health with the fracture that may cause because fall, and it highly depends on the individual balance that whether can effectively draw oneself up.

In the daily life of every day, people stand with walking process in usually adopt swing, rather than motionless self balance that keeps of standing erectly.Healthy people's swing generally is a fore-and-aft direction, yet, there is multiple health problem can cause improper swing and demonstrates equilibrated improper property.If a people has the words of equilibrium problem sideshake will occur, such people has the higher risk of falling.Balance and balanced capacity rely on three main sensory systems (vestibule, vision, somesthetic sensibility), by the central nervous system balancing response are regulated and control simultaneously.In recent years, computerized posturogaphy has obtained significant progress, and computerized posturography technology is compared with simple motion test, can more accurate, more objective, more effective assessment equilibrium function.The central principle of all these systems all is to measure the posture swing, by the Move Mode reflection of Center of Pressure point, by the sensor senses on the measuring table.This Move Mode can perhaps be converted into computerized score value by the form that is rendered as fluctuation of visualization.Allow the measured take various state (open eyes, close one's eyes or the like) or the testee is caused the posture pressurized by traction, promotion, inclination measurement platform, the testee handles the independent reaction of being taked to these can be evaluated, thereby the extraneous information about testee's equilibrium problem is provided.

The index parameters of falling is the calculation of parameter that is obtained by individual balance test and coming, and it comprehensively represents and has disclosed individual because the risk of falling that the balanced capacity disorder causes.Each parameter of measuring has disclosed the ability or the obstacle of testee specific region.Therefore, a large amount of problems, can both be differentiated out by the result of balance test to the orthopaedics problem from neurologic problems, and each problem all can present unique resulting schema, the result of display abnormality on specific parameter on the posture conclusive table.

The utility model content

This utility model is a kind of based on the posturography technology, be applied to the body balance detector that pressure on the platform is estimated measured's balance and stability by measuring the measured vola, comprise a force plate/platform, with a microcomputer that the total balance of the body evaluating software is installed, it is characterized in that force plate/platform is connected with microcomputer by data wire.Force plate/platform is main form (as shown in Figure 1, 2) by four balance plates, four balance plates carry the ball of foot and the heel of two feet respectively, also be included as the set handrail of security consideration and can regulate the platform of level and the data line interface that can carry out data transmit-receive, the posturography measuring transducer is placed on the measured underfooting, suffered pressure on the measuring table.The fluctuation of four balance plates evaluation and test pressures changes, and signal is passed to microcomputer, is judged and is assessed pressure on each force-detecting position relation between changing by airborne software, and draw the human body comprehensive equilibrium index.In the whole testing time, the different parts of testee's foot is because the swing of health produces various different pressures, under various different situations, can assess testee's balanced capacity, comprise out/sleep eyeball, adjust measuring table, make head be in the various situations of diverse location.

This utility model provides abundant biofeedback training program, by training, has the individuality of equilibrium function obstacle can improve they self ability of posture control ability, thereby improves balance and stability.Simultaneously, the biofeedback training pattern provides the function of training athlete in the different directions motor capacity, helps the athlete to improve their training achievement.

Software and hardware by specialized designs be used to measure and assess be applied to four on the force-detecting position pressure oscillation and the mutual relation between each force-detecting position measurement result.Measuring method is to allow measured front and back sole stand in respectively on four force-detecting positions, measures the testee then and is applied to four pressure on the force-detecting position.The measured adopts each posture respectively to stand about 30 seconds, and the whole measuring process time of standing is less than 5 minutes.These postures, comprise open eyes, close one's eyes, head rotation, increase callosity stand etc., and the essential information of each system of equilibrium function can be provided.All metrical informations can be stored, called, printing test information table, the vertical information contrast of case and teledata are shared.

The specific embodiment

As depicted in figs. 1 and 2, four blocks of balance plates are in twos in conjunction with constituting two balancers, each balancer uses for a foot, and measuring station stands in the pressure under the patient's ball of foot and heel on the balancer, a microcomputer, by specific software collection and analytical information, produce the balance assessment result.The balance evaluating system is measured balance and posture swing under various postures, every kind of posture all reflects the influence of swing to balance.The balance evaluating system is with four pressure flats, measure the pressure at testee's heel and ball of foot position respectively, this method makes us carry out interaction analysis between each position of foot, and resulting information is very valuable to the effect of balance aspect for distinguishing various diseases.Coefficient of stability is interrelated with factors such as " transfer modes of center of gravity " with " wobble area ", " amplitude of fluctuation ", " swing speed " of posturography device measuring.
