Three-dimensional space body position sensation testing device and method

Abstract

The invention discloses a three-dimensional space body position sensation testing device. The testing device comprises a sliding rod, a sliding block, a displacement sensor, an operating rod, a potentiometer, an elastic bandage and a controller, wherein the sliding block is provided with a groove, the sliding rod is clamped in the groove, and the sliding block moves along the sliding rod; the displacement sensor is arranged on the sliding rod and used for detecting the displacement of the sliding block; the operating rod is coaxially connected with the sliding rod; the potentiometer is arranged on the operating rod and used for detecting a swing angle of the operating rod; the controller is connected with the potentiometer and the displacement sensor and determines space coordinates of thesliding block according to the displacement of the sliding block and the swing angle of the operating rod; and the elastic bandage is bound with the sliding block and used for fixing the human body testing position. According to the invention, the space coordinates of the sliding block are determined according to the displacement of the sliding block and the swing angle of the operating rod, andthus the space position coordinates of the human body position can be accurately determined.

Description

technical field [0001] The invention relates to the field of position sense testing, in particular to a three-dimensional body position sense testing device and method. Background technique [0002] The infrared motion capture system can obtain data such as the joint angle of the subject, but the operation is complicated and requires a long-term trained professional to operate. And because there is no special proprioceptive position sense test function, and there is no visual feedback on the test joint angle during positioning, it is difficult for the subjects to ensure the accuracy of positioning. The collected data also needs to be manually recorded and calculated and analyzed, which increases the error of human operation. [0003] At present, the position sense of the human body is mostly concentrated on a single plane or a single axis. Therefore, the obtained test results are only part of the information about the proprioceptive position sense of the upper limbs, and ca...

Problems solved by technology

[0003] At present, the position sense of the human body is mostly concentrated on a single plane or a single axis. Therefore, the obtained test results are only part of the information about the proprioceptive position sense of the upper limbs, and cannot fully detect the position sense of the human body, making the detection results inaccurate. precise
