Description
Technical field
This utility model gait analysis device belongs to field of medical device.
Background technology
Walking is prevailing motion mode, and the gait of the mankind is one-period and reliable circulation, and it has basic pattern, can be assessed the function of musculoskeletal system by gait, and gait can provide a lot of information in a short period of time; And so many information makes observer all grasp.Therefore, the necessity of gait message file is facilitated the development of gait analysis meter.
Gait analysis is used to the assessment of ability of walking to individuality, plan, treatment.Wherein gait analysis is the basis for the treatment of, collects and kinesiology, biology, nerve reconstructive such as to reinvent at the combination to the attitude of patient, is beneficial to provide rational therapeutic scheme and corresponding therapeutic equipment uses.
The method of current existing Measurement and analysis gait has following several:
1. footprinting: be make to detect by an unaided eye, does some simple time and space records.Sprinkling pulverized limestone on the ground, allowing person to be measured in the Distance geometry time of recording person to be measured walking sprinkled with walking in the ground of pulverized limestone simultaneously.To walk rear observation and measuring sprinkled with the ground footprint of pulverized limestone, thus drawn the result of gait analysis.There is a lot of significantly defect in this method, such as: time is long; Need at substantial manpower; Analyze based on subjectivity, accuracy is lower; The data obtained are less; Clinical report hand filling, wastes time and energy and easily makes mistakes.
2. video method: human walking procedure is absorbed by video equipment (CCD photographic head), then frame by frame pointwise carry out dot-matrix analysis, its advantage is that equipment is simple, experimenter's gait is more natural, but because its analyzing and positioning mainly relies on manually, higher to operation requirements, application condition is large, and can only two dimensional surface analysis be carried out, the degree of accuracy of three-dimensional spatial analysis can not be guaranteed.
3. form: the Infrared being accepted skin-marker transmitting or reflection by infrared camera, and send out according to corresponding model analysis, carry out three-dimensional reconstruction, thus draw the 3 D motion trace that partes corporis humani divides.Its advantage is technology maturation, and data result is accurate, simple and quick; Shortcoming has requirement to the position of pasting reflective spot, pastes directly will definitely not affect measurement result; Foreign body can not be had in measuring process to keep off between reflective spot and photographic head, comprise tested personnel self, so tested personnel side can not be accompanied or be assisted personnel in.Otherwise affect data acquisition; Higher to environmental requirement, need to be equipped with the larger room of what a area, after photographic head installs angle, can not arbitrarily change; Expensive, operating process is responsible for, and majority uses at laboratory, seldom sees at Clinical practice, and the phase that limits to a certain extent promotes.
4. ultrasonic type: the principle of ultrasonic type is similar to form, the ultrasonic emitting probe carried by body surface sends ultrasound wave, and the ultrasound wave receiving transducer through surrounding accepts, and arranges according to certain model, carry out three-dimensional reconstruction, draw the 3 D motion trace of human body.Its advantage is equipment price relative moderate, and operation is also relatively simple, and data are also more accurate; But ultrasound wave easily reflects, must eliminate the interference of surrounding objects, require higher to surrounding, simultaneously because gauge point volume is comparatively large, the gauge point quantity that body once carries has certain restriction, is only suitable for carrying out human body Segmental analysis.
This utility model gait analysis device, for defect, can realize the output digitized of measurement result, solve the error that artificial subjective reason causes, measure precisely, the reference data of measurement result and Healthy People is compared, further, gait is proposed to the treatment training of the situation that meets.
Utility model content
For solving the problem, this utility model provides gait analysis device.
Gait analysis device, comprises sensor, data logger, nylon tape, and sensor transfers to data logger by data.
Wherein, described sensor and data logger are fixed on foot and waist respectively by nylon tape.

The acceleration in sensor record foot X, Y, Z tri-directions and speed wherein X are gait fore-and-aft direction, and Y is gait left and right directions, and Z is gait above-below direction.
Further, by acceleration a, can obtain speed V and displacement S, concrete conversion is as follows:
Speed VX==t*(an+an+1)/2;
Speed VY==t*(an+an+1)/2;
Speed VZ==t*(an+an+1)/2;
Displacement SX=t*(vn+vn+1)/2;
Displacement SY=t*(vn+vn+1)/2;
Displacement SZ=t*(vn+vn+1)/2;
Wherein t is the time, and n is timeslice, and n is next timeslice, and to record data break be 10ms.
Described sensor most preferably is inertial sensor, is made up of three axis accelerometer and three-axis gyroscope two parts, and three axis accelerometer is used for acceleration measurement, and three-axis gyroscope is used for taking measurement of an angle.
This utility model gait analysis device, its innovative point has:
1) measure precisely, there is not the error that subjective reason causes;
2) have by measurement result export realize digitizing function;
3) reference data of measurement result and Healthy People can be compared, further, gait be proposed to the treatment training of the situation that meets;
4) device is simple and convenient carries and can come into family armarium.
Below in conjunction with accompanying drawing and specific embodiment, the utility model is described in further detail.
