Description
Technical field
This utility model relates to sports psychology's technical field, specifically, relates to for large arm and forearm side-sway
Actively kinaesthesia Azimuth testing device.
Background technology
Kinaesthesia belongs to internal sense, and the feedback information of kinaesthesia almost participates in all of perception.First, kinaesthesia is felt the mankind
During knowing extraneous things, there is important function；Secondly, kinaesthesia has substantial connection with the speech event of the mankind；Kinaesthesia is the most same again
Other feel to be associated, and distinguish object soft or hard, the touch-pressure sensation of the characteristic such as concavo-convex, smooth as sense of touch and pressure sensation contact to be formed, can
To provide the signal such as body form, size, us are helped to recognize the world；Finally, kinaesthesia is various voluntomotory bases.As
Described in Xie Qienuofu, people is mainly the objective world that recognized by muscular movement and taken on a new look, and people is without reaching highly essence
True kinaesthesia, it is then not possible to realize any strict accurate motion.
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
The impact that kinaesthesia is distinguished by change.
In prior art, there is the part research about kinaesthesia orientation discrimination device.Analyze from structure, existing distinguish
Device mainly includes 180 ° of semicircle dip sticks, is hinged with a rotation chi in the centre of dip stick, rotates and has for referring on chi
To the pointer of semi-circle ruler.
Before test, being then placed on desktop by semi-circle ruler, the base of semi-circle ruler is parallel with table limit, and subjects is seated at a limit,
Being placed on the center of circle by elbow, middle finger is directed at 0 scale.Then subjects is made to observe 0 °～the position of 180 ° on semi-circle ruler, finally profit
With eyeshield, the eyes of subjects are blinded.
During Passive Test, main examiner, using the elbow of subjects as rotating shaft, holds the wrist of subjects, in then turning to
Refer to arbitrary number of degrees of indication, allow subjects report and feel to move how many degree, and the record report number of degrees, do not inform subjects simultaneously
Result accuracy.Finish 10 positions, 2 times, each position, 20 times altogether, and record in the same manner.
When actively testing, make the elbow of subjects as rotating shaft, then turn to main examiner and specify reading.After rotation completes
Report main examiner, main examiner observes rotation error, does not inform the result accuracy of subjects simultaneously.Finish in the same manner
10 positions, 2 times, each position, 20 times altogether, and record.
Finally, according to:
Relative error=mean error/movement number of degrees；

(2) there is certain error in artificial reading.
(3) elbow of subjects is not relatively fixed device with rotating chi, therefore easily occurs elbow to take off in test process
From the situation rotating chi.
(4) in test process, middle finger can occur a certain degree of skew, affects final result and judges.
(5) existing test device, is only capable of test forearm precision in the horizontal plane, for non-horizontal surface, large arm
And/or leg, all cannot test.
Therefore, how to design a kind of kinaesthesia Azimuth testing device with relatively high accurancy and precision and higher credibility, avoid
Test result is interfered by objective factor, is those skilled in the art's problems of needing solution badly.
