Current advances in the treatment of myofascial pain syndrome with trigger point injections: A review

Myofascial pain syndrome (MPS) caused by trigger points in muscles is a common cause of local or generalized pain, which is clinically common, has a high incidence, and has no specific cure. The most popular and widely used clinical method mainly targets the trigger point for treatment, i.e. trigger point injection (TPI) therapy. The injectable drugs mainly include glucose, saline, local anesthetics, botulinum toxin type A, platelet-rich plasma, platelet-poor plasma, steroid preparations, etc. This method is low cost and less invasive, and early clinical applications have shown good efficacy. In this paper, we have reviewed clinical research progress in treating MPS with TPI therapy.
