First of all, it should be positively affirmed that electrothermal therapy has a very good effect on patients with osteoarthritis, and it is very effective. Electrothermal therapy can promote local blood circulation and thereby facilitate the absorption of local inflammatory exudates, which can effectively alleviate the pain symptoms caused by osteoarthritis. Additionally, for osteoarthritis patients, besides electrothermal therapy, they can also take oral non-steroidal anti-inflammatory and analgesic drugs and drugs that nourish cartilage for treatment. Moreover, it is necessary to reduce the amount of exercise, minimize local irritation as much as possible, and persist in applying local heat compresses or hot washing daily. During hot washing, Sichuan peppercorn and salt could be added to the hot water for the treatment.
