Abstract
The invention discloses a three-dimensional gait analyzing device which comprises a data recording module, a main control computer and a data collecting module. The three-dimensional gait analyzing device is used for evaluating, planning and treating the individual walking ability. Gait analysis is the base of treatment, and collection of gestures of a patient, kinematics, biology, nerve reestablishment and remodeling and the like are combined so that a reasonable treatment scheme can be easily given, and use of corresponding treatment equipment can be facilitated.
Description
Technical field
The invention belongs to the gait analysis device of limbs, be a kind of three-dimensional gait analysis device further, belong 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.
A kind of three-dimensional gait analysis device of the present invention, 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.

A kind of three-dimensional gait analysis device, is characterized in that: comprise data recordin module, main control computer, data acquisition module;
Described data acquisition module, for gathering acceleration signal, angle signal;
Described data acquisition module is transmitted Signal transmissions to data recordin module by data;
Described main control computer obtains the signal of data recordin module by data transmission;
Described data acquisition module gathers the three-dimensional space data of X, Y, Z of foot respectively;
Further, data acquisition module measures acceleration a and the angle θ of X, Y, Z;
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;
