Description
Technical field
This utility model belongs to sports psychology's technical field, specifically, relates to a kind of simulated weightlessness sagging
Straight in the active 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, the namely sensation in muscle, tendon and joint, i.e. somesthetic sensibility.Its reflection position of body parts, motion and muscle
Tensity, be a kind of important morphological of internal sense.
Kinaesthesia is voluntomotory important foundation, is the motion to oneself health and the sensation of location status.When joint is stretched
Bend or muscle relax contracting time, will stimulate these sensors, produce neural impulse, along spinal cord conduction, in corticocerebral
Return before centre and produce kinaesthesia.
By kinaesthesia, people can be made to perceive the motion conditions of the locus of oneself health, posture and body parts.People
Kinaesthesia owing to having high precision, coordination could be realized, complete the motor skill of various complexity.
Getting rid of under conditions of vision, by limbs touch motion can correctly the size of consciousness object, shape and
Elastic.Hands is the change of muscle tone when motion, teaches that the kind attribute of object.
In voluntary movement, due to continuous incoming brains of signal such as the speed of muscular movement and intensity, form feedback information,
The brain neuroregulation to muscular movement could be realized, make voluntary movement be possibly realized.Believe without accurate kinesthetic feedback
Breath, will result in movement disorder.The people's correct reflection to objective world, is the various results felt mutually coordinated, be mutually authenticated.
Kinaesthesia various sensations mutually coordinated in play an important role.Without kinaesthesia and the combination of other sensations, people knows
Feel ability cannot be developed normally.
The susceptibility of child's kinaesthesia improves with the growth at age, and common people usually can not directly aware kinaesthesia information,
But for outstanding athlete, they are the most sensitive to the motion in body muscle, tendon and joint, to speed, action
The appraisal of precision and stability has fine oneself's impression.
Kinaesthesia whether sensitivity be select athletes, dancer, one of the essential condition of acrobat.
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 make subjects observe the position of 0 °-180 ° on semi-circle ruler, finally utilize
The eyes of subjects are blinded by eyeshield.
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；
Calculate the mean error of 10 positions.In this, as the important reference selected athletes.
But, above-mentioned device, there is certain defect.Including:
(1) it is limited to semi-circle ruler and rotates chi precision, test process can exist certain error.
(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.
(6) existing test device, order 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 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.
