[0043] When in use, first, the legs and ankles of the patient are detected. At this time, the patient lies flat on the lying bed 30, and the patient's sole contacts the second sole support plate 108. The medical staff fixes the patient's sole on the second sole support plate 108 through the first strap 107. After the patient's soles are fixed, the medical staff operates the needle electromyogram device to make the patient's sole perform the pressing-down and hooking-up actions. When the patient's sole performs the pressing-down and hooking-up actions, it will drive the second sole support plate 108 and the first sole support plate 106 to swing up and down. At this time, through the first tension detector 109 on the support vertical plate 101, the tension detection of the patient's sole pressing-down and hooking-up actions will be completed, and through the first display 60, it is convenient for the medical staff to record data. After the tension detection of the patient's sole pressing-down and hooking-up actions is completed, then, the medical staff operates the second handle 112 and the limit insertion plate, so that the first insertion post 115 can be inserted and fixed with the two first card holes 117 on the limit insertion plate 116, which is convenient for the left end face of the limit insertion plate 116 to slide inside the second protective cover 114. After the left end faces of all the limit insertion plates 116 slide inside the second protective cover 114, the medical staff operates the needle electromyogram device to make the patient's sole perform the centering swing and the outward swing. When the patient's sole performs the centering swing and the outward swing, it will drive the second sole support plate 108 to swing, so that the arc slider 123 on the second sole support plate 108 slides inside the arc groove 120. At this time, the two second tension detectors 119 inside the arc groove 120 will detect the tension during the swing and display the data through the first display 60;

[0044] Second, when detecting the tension at the patient's knee joint, the medical staff operates the needle electromyogram device, so that the patient's knee joint will show a pressing-down phenomenon. At this time, the arc pressing post 201 in the knee joint auxiliary tension detection mechanism 20 will be pressed down, so that the third tension detector 204 can detect the pressing-down force, thereby completing the tension detection work at the patient's knee joint;

[0045] Third, when detecting the patient's arm, wrist and fingers, the patient places one arm on the hand pulling force detection component of the hand auxiliary pulling force detection mechanism 50; when detecting the fingers, the patient places the palm down and the back of the hand up, and binds the third strap 511 to the patient's fingers. The medical staff operates the needle electromyogram device to make the patient's fingers curl up, pulling the third strap 511 and the corresponding second pull rope 521 of the third strap 511, thereby pulling the first sliding plate 516, so that the fifth pulling force detector 518 can detect the pulling force for pulling the first sliding plate 516, and display the detection data through the second display 503; when detecting the wrist, the patient places the palm up and the back of the hand down, and binds the second strap 510 to the patient's palm. The medical staff operates the needle electromyogram device to make the patient's palm bend upward, pulling the second strap 510 and the corresponding second pull rope 521 of the second strap 510, so that the first sliding plate 516 is pulled again, facilitating the fifth pulling force detector 518 to detect the pulling force for pulling the first sliding plate 516 again, and the second display 503 will also display the detection data again. After completing the detection of one hand, the medical staff adjusts the position of the hand pulling force detection component to the other hand of the patient, and completes the detection of the patient's fingers and wrist through the above steps; after completing the detection of the patient's fingers and wrist, the medical staff adjusts the position of the hand pulling force detection component to the top of the patient's head, and by loosening and tightening the fastening bolt 505 on the mouth-shaped sleeve column 513, it is convenient for the column 506 to slide up and down inside the mouth-shaped sleeve column 513 to complete the height adjustment work of the hand pulling force detection component. After completing the height adjustment work, the patient holds the two pulling force grips 508 with both hands. At this time, the medical staff operates the needle electromyogram device to make the patient's arm move and pull the two pulling force grips 508 outward. At this time, the second sliding plate 519 will be pulled outward through the first pull rope 514, so that the fourth pulling force detector 515 can detect the pulling force pulled outward, and display the detection data through the second display 503. After completing the pulling force detection in one direction, the medical staff operates the third handle 501 and rotates the swing seat 502, and the second plug post 522 will be inserted into the multiple second card holes 523 on the swing seat 502 to complete the plugging work, thereby completing the angle adjustment work of the swing seat 502, facilitating the patient to complete the pulling force detection work of arm stretching at multiple angles.
