There is a lot of orthopedic training in the market, but the level is uneven. If you are not qualified as a doctor, have no basic knowledge of anatomy, rehabilitation and exercise physiology, and blindly participate in some short and fast training (you have seen someone being pulled by a side wrench), it is easy to have an accident.

I think teacher Yan's tendon-dredging course is good. She is an apprentice of Luo Youming, an old lady in Shuangqiao, Beijing, and a special clinical expert of Beijing University of Chinese Medicine. I have nothing to say professionally. The key is that the technology is safer, and the key is that online classes are not expensive, which is much more cost-effective than thousands of offline trainings.
