The appropriate dosage (frequency of application) of SMT needed to achieve optimal pain relief for patients with MTrPs has not been established. Haas et al. performed a pilot randomized controlled trial to examine the dose response relationship between SMT and cervicogenic headaches. The results showed there is a dose-response relationship, increasing the dose of SMT leads to a decreased frequency and intensity of headaches. Additionally, Haas and colleagues conducted a pilot study to make a preliminary identification of the number of chiropractic manipulations required to decrease chronic low back pain and disability. The results showed a positive dose-response relationship between SMT and low back pain. Dose-response for MTrPs has yet to be established in the current literature. This preliminary work will determine the proper dose-response for cSMT in the treatment of MTrPs in one single visit.
