Clinical Trial Summary

To see if there is there any difference in the treatment outcomes/results such as changes in pain intensity in patients with myofascial pain who have been treated with trigger point injections or twin block?

Description:

Most treatment approaches for chronic myofascial pain are not evidence-based. Studies are usually controversial. Most are short-term, non-randomized. An essential limitation has been the lack of standardization of diagnosis. Some studies do not differentiate between joint pain and muscle pain, which can significantly affect the outcome of the treatment provided.

Diagnostic Criteria for Temporomandibular Disorders (DC/TMD) was recently published and validated. Their protocol allows standardization of the assessment and diagnosis of patients with temporomandibular disorder, including myofascial pain.

To the investigator's knowledge, no previous prospective, randomized study has been conducted demonstrating the treatment outcomes of either trigger point injections or twin block in patients with chronic myofascial pain.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Pain relief: numerical pain scale	The pain relief received from each injection will be measured using the numerical pain scale. This scale is between 0-10 with 0 meaning no pain and 10 is the most pain.Higher values represent worse pain.	6 months
