Regarding the question of whether electrothermal therapy is effective for tenosynovitis. First, it needs to be affirmed that electrothermal therapy is beneficial for patients with tenosynovitis. The primary purpose of electrothermal therapy is to promote local blood circulation and facilitate the absorption of inflammatory exudates, which can effectively alleviate the clinical symptoms of the patient's tenosynovitis, and the results are quite good. Therefore, patients with tenosynovitis can undergo electrothermal therapy. In addition, for patients with tenosynovitis, local injections, topical plasters that activate blood circulation and remove blood stasis, and daily local hot washing can also be performed. Hot washing with Sichuan pepper and salt in hot water is usually sufficient. For patients with severe tenosynovitis, it is necessary to actively pursue surgical treatment.
