A testing device for multi-joint isokinetic training of upper limbs

Abstract

The invention provides a multi-joint isokinetic training and testing device for upper limbs. On the test training seat, an upper limb testing and training mechanical arm is installed, including seven-section connecting rods connected in sequence by six independently controlled motors, including connecting the seat The first link of the chair and the handle at the end, when in use, the tester's arm penetrates the inner ring of the turntable bearing, and holds the handle forward. During training or testing work, the control center calculates various driving parameters based on the screw theory, combined with the feedback information of the position sensor and the torque sensor, and outputs the output to drive the rotation of six motors at six joints to achieve The isokinetic movement of the handle at the end of the multi-joints controls each connecting rod to drive the tester's arm for constant-kinetic training and testing. The multi-joint isokinetic training and testing device for the upper limbs disclosed by the invention greatly simplifies the structure of the isokinetic training and testing device, and improves the control efficiency.

Description

technical field [0001] The invention relates to the fields of medical rehabilitation and sports fitness, in particular to an upper limb multi-joint isokinetic training test device. Background technique [0002] The human or animal body relies on muscle contraction to generate force, which drives the bones connected at both ends of the muscle to rotate around the joints between the bones. Muscle contractions can generally be divided into two basic movements: isotonic contraction, in which muscle output tension remains constant while muscle length changes; and isometric contraction, in which muscle length remains constant and muscle output tension changes . Of course, most muscle contractions are a combination of both. [0003] Medical rehabilitation and sports fitness are mainly about making muscles move. At present, a new test training concept of isokinetic movement is proposed: during the joint movement, the resistance applied to the end of the bone changes, so that the ...

Problems solved by technology

[0007] However, most of the isokinetic testing and training instruments on the market today are blocked by foreign technology. They are large in size, heavy in quality, and expensive in price. Moreover, the products can only be tested and trained for different single joints, and the testing efficiency is low and the effect is not good.
