Description

Perpendicular to the passive kinaesthesia Azimuth testing device of people's body axis under simulated weightlessness

Technical field

This utility model belongs to sports psychology's technical field, specifically, is that to be related to a kind of simulated weightlessness sagging Directly in the passive kinaesthesia Azimuth testing device of people's body axis.

Background technology

Kinaesthesia (kinesthetic sense) be also sensation of movement, is the position to parts of body and moving situation Sensation, that is, the sensation in muscle, tendon and joint, i.e. somesthetic sensibility.It reflects position, motion and the muscle of body parts Tensity, be a kind of important morphological of internal sense.

Kinaesthesia is voluntomotory important foundation, is motion to oneself body and the sensation of location status.When joint is stretched Bend or muscle relax contracting when, will stimulate these sensors, produce neural impulse, conduct along spinal cord, in corticocerebral Return before centre and produce kinaesthesia.

By kinaesthesia, can make one to perceive the motion conditions of locus, posture and the body parts of oneself body.People Kinaesthesia due to having high precision, just enable coordination, complete the motor skill of various complexity.

Exclusion vision under conditions of, by limbs touch motion can correctly the size of consciousness object, shape and Elasticity.The change of handss muscle tone in motion, teaches that the kind attribute of object.

In voluntary movement, due to signal constantly incoming brains such as the speed of muscular movement and intensity, form feedback information, Just enable the neuroregulation to muscular movement for the brain, so that voluntary movement is possibly realized.Without accurate kinesthetic feedback letter Breath, will result in movement disorder.The correct reflection to objective world for the people, is the various result felt mutually coordinated, be mutually authenticated. Kinaesthesia various sensations mutually coordinated in play an important role.Without the combination of kinaesthesia and other sensations, people knows Feel ability cannot normally be developed.

The susceptibility of child's kinaesthesia improves with the growth at age, and common people usually can not directly be aware of kinaesthesia information, But for outstanding athlete, they are very sensitive to the motion in body muscle, tendon and joint, to speed, action The appraisal of precision and stability has self fine impression.

Kinaesthesia whether sensitivity be select athletes, dancer, one of the essential condition of acrobat.

In prior art, there is the research with regard to kinaesthesia orientation discrimination device for the part.Analyze from structure, existing distinguish Device mainly includes 180 ° of semicircle measuring scales, is hinged with a rotation chi in the centre of measuring scale, rotation chi has for referring to Pointer to semi-circle ruler.

Before test, then semi-circle ruler is placed on desktop, the base of semi-circle ruler is parallel with table side, subjectss are seated at table side, Elbow is placed on the center of circle, middle finger is directed at 0 scale.Then the position making subjectss observe 0 ° -180 ° on semi-circle ruler, finally utilizes The eyes of subjectss are blinded by eyeshield.

During Passive Test, main examiner, using the elbow of subjectss as rotating shaft, holds the wrist of subjectss, in then turning to Refer to arbitrary number of degrees of indication, allow subjectss' report to feel to move how many degree, and the record report number of degrees, do not inform subjectss simultaneously Result accuracy.Finish 10 positions in the same manner, each position 2 times, 20 times altogether, and record.

When actively testing, the elbow making subjectss, as rotating shaft, then turns to main examiner and specifies reading.After the completion of rotation Report main examiner, main examiner records rotation error, does not inform the result accuracy of subjectss simultaneously.Finish in the same manner 10 positions, each position 2 times, 20 times altogether, and record.

Finally, according to：

Relative error=mean error/movement the number of degrees；

Calculate the mean error of 10 positions.In this, as the important reference selecting athletes.

But, above-mentioned device, there is certain defect.Including：

(1) it is limited to semi-circle ruler and rotation chi precision, in test process, can there is certain error.

(2) there is certain error in artificial reading.

(3) elbow of subjectss and rotation chi are not relatively fixed device, easily occur elbow to take off therefore in test process Situation from rotation chi.

(4) in test process, middle finger can occur a certain degree of skew, and impact final result judges.

(5) existing test device, only can test forearm precision in the horizontal plane, for non-horizontal surface, large arm And/or leg, all cannot test.

(6) existing test device, makes test position in rotation process, is affected by gravity all the time, there is certain mistake Difference.

Therefore, how to design a kind of kinaesthesia Azimuth testing device having compared with high accurancy and precision and higher credibility, to avoid Objective factor interferes to test result, is the problem of those skilled in the art's urgent need to resolve.
