Description for medicine or protocol of treatment in detail:

Test group: Lie on your back, with a soft pillow placed under your knees to fully expose the identified tendon nodes. The musculoskeletal mode was selected by ultrasound. The median line was opened, and the body surface positioning points of the fascia nodes were placed on the median line. The ultrasound image was observed. Under ultrasound, the lesion points through the fascia often had abnormalities such as enhanced echo of the perimytoma, thickened perimytoma, thickened synovium, bursae effusion, and changes in the echo signals of ligaments and tendons. The acupuncture points were selected at the palpated hard lumps and cords, combined with the positions of abnormal acoustic image signal changes under ultrasound. The acupuncture path was designed under dynamic ultrasound observation and the skin needle entry points were determined. The determined needle entry points should not only avoid damaging important blood vessels and nerves along the puncture path with the puncture needle, but also facilitate ultrasound-guided operations. Acupuncture needles with a diameter of 0.40mm x 75mm are used. First, hold the diseased muscle cord with the left hand, and insert the needle vertically at a distance of 2cm from the target muscle with the right hand. After inserting the needle, adjust the direction of the needle to make it pass diagonally through the diseased muscle bundle. After the needle is punctured, the needle is retracted under the skin, and the direction of the needle is slightly adjusted to penetrate the diseased muscle bundle again. Repeat this process 2 to 3 times before removing the needle. The indication of the softening effect of the muscle bundle after the needle is observed, and no needle is retained. After needling, perform a physical examination by palpation again. If the muscle bundles become soft, stop the needling; if not, proceed with another needling. Acupuncture reaction: During the acupuncture process, the patient may experience obvious soreness, numbness, distension and pain. Local muscles may also have twitching reactions, and the number of muscle beats should be recorded. Instruct the patient to avoid contamination of the treatment area within 8 hours to prevent infection. Depending on the total number of tendon nodes to be treated, 4 to 8 points should be treated each time (if 8 or more treatment points can be found, treatment is sufficient), twice a week, each time lasting about 20 minutes, for two consecutive weeks, all completed by the same group of treating physicians.
Control group: No acupuncture treatment was received during the study period, and the same acupuncture treatment was given after the study ended.
