Description
Technical field
This utility model is related to sports psychology's technical field, specifically, be related under simulated weightlessness large arm with
The passive kinaesthesia Azimuth testing device of forearm forward swing.
Background technology
Kinaesthesia belongs to internal sense, and the feedback information of kinaesthesia almost participates in all of perception.First, kinaesthesia is felt in the mankind
During knowing extraneous things, there is important function；Secondly, kinaesthesia and the speech event of the mankind have substantial connection；Kinaesthesia is again often same
Other feel to be associated, as tactile and pressure sensation contact form the touch-pressure sensation distinguishing object soft or hard, the characteristic such as concavo-convex, smooth, can
To provide the signals such as body form, size, us are helped to recognize the world；Finally, kinaesthesia is various voluntomotory basis.As
Described in Xie Qienuofu, people is mainly the objective world that recognized and taken on a new look by muscular movement, and people is highly smart without reaching
True kinaesthesia is it is then not possible to realize any strictly accurately moving.
Kinaesthesia whether sensitivity be select athletes, dancer, one of the essential condition of acrobat.Particularly in dancing
In motion, the order of accuarcy of arm directly influences dancing posture accuracy of action and politeness.Therefore, distinguish frequently with kinaesthesia orientation
The individual variation of other the effects kinaesthesia susceptibility.Understand the difference of different tested human arm kinaesthesia orientation discriminations, orientation
Change the impact that kinaesthesia is distinguished.
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 make the position that subjectss observe 0 °～180 ° on semi-circle ruler, finally profit
With eyeshield, the eyes of subjectss are blinded.
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 observes 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.
