Description

Human Balance Test Device

technical field

The disclosure relates to a balance test device capable of evaluating the dynamic balance ability and posture control ability of the upper limbs and lower limbs of a human body, especially for the Y balance test.

Background technique

There are many test methods to measure the balance ability of the human body, among which the Y-Balance Test is more popular. The Y balance test is a comprehensive functional test that evaluates the dynamic balance ability of the upper and lower limbs and the postural control ability of the human body. It includes two sub-tests, the dynamic balance of the upper limbs and the dynamic balance of the lower limbs. The limbs on the other side are stretched farthest in the prescribed three directions. It can quantify the joint flexibility and stability, core stability, strength, neuromuscular control, proprioception and other comprehensive abilities required by the human body when performing related actions. It is mainly used for preventive screening of sports injuries and rehabilitation of upper and lower limbs and return to competition assessment and other fields.

The Y balance test mainly compares and analyzes the difference between the reach distance of the left and right limbs in each direction and the comprehensive value of each sub-test to quickly evaluate the limited dynamic balance ability, functional symmetry and injury risk of the upper and lower limbs. The existing Y balance kit needs to measure the distance manually, there are certain errors, and the analysis and calculation of the measurement data is cumbersome, the measurement personnel cannot immediately make an evaluation conclusion, which often delays the time of the test and evaluation, and cannot be fast and convenient.

Detailed ways

FIG. 1 shows a human body balance test device according to an embodiment of the present disclosure, the human body balance test device includes a plurality of measuring arms 1 , a measuring platform 4 for supporting a human body, and a plurality of distance measuring sensors 8 . The measuring arm 1 includes a rail 2 and a slider 3 that can slide on the rail 2 . The track 2 can be a groove structure, a part of the slider 3 is placed in the groove, and the other part is exposed to facilitate the tester to push when stretching out. The track 2 is connected to the measuring platform 4 in a clamping manner, which is convenient for disassembly. The track 2 and the measuring platform 4 can also be connected by bolts, and the present disclosure does not limit the specific connection method of the two.

The distance measuring sensor 8 is used to measure the moving distance of the slider 3 . The distance measuring sensor 8 can be installed on the measuring platform 4, and the measuring signal 7 emitted by it is projected to the slider 3 through the groove. As an alternative, the ranging sensor 8 can also be installed at the end of the track 2 (the end away from the measuring platform 4), so that the interference of the limbs during the test can be avoided. The ranging sensor 8 can be an infrared distance sensor. It can also be a combination of an infrared distance sensor and a capacitive distance sensor or an ultrasonic distance sensor. The detection distance of the ranging sensor 8 is the fusion of the output values of the infrared distance sensor and the capacitive distance sensor or the ultrasonic distance sensor.

The terminal device 5 can be a smart phone, a handheld computer, a personal computer, and the like. The terminal device 5 sends a start test command to the controller, triggering the distance measuring sensor 8 in the corresponding direction to emit the measurement signal 7 . During the test, when the tester stretches the slider 3 at the farthest distance, the distance measuring sensor 8 transmits the measured signal to the controller in real time, and the controller records the data from the measurement signal 7 sent to the return received. The elapsed time is used to calculate the moving distance of the slider 3, and then the moving distance is sent to the terminal device 5 through the communication module, and the terminal device 5 performs data collection and analysis.
