Revalidation of Trigger Point Injection in Myofascial Pain Syndrome, Assessed by Pain Disability Score
Journal Title: INTERNATIONAL JOURNAL OF SCIENTIFIC STUDY - Year 2017, Vol 5, Issue 1
Abstract
Background: Myofascial pain syndrome (MFPS) is defined as the “sensory, motor, and autonomic symptoms caused by myofascial trigger points (MTrPs)” and is a recognized medical diagnosis among pain specialists. MFPS continues to be one of the most commonly missed diagnoses. It has been estimated that some 44 million Americans have myofascial pain problems. Local anesthetic is the most common drug effectively used for injection into trigger points. The tool for assessment is usually the pain score (either visual analog scale or numerical rating scale). However, the patients with MFPS suffer from pain, depression, and other psychosocial factors, which contribute to their disability. Materials and Methods: In this prospective, sequential study, 30 patients were selected for the study. The pain disability questionnaire was filled up on the first visit and was used as control. Patients were then given trigger point injections on 1st, 7th, and 30th day, and the questionnaire was again filled up at 1 month from the day of 3rd injection. All the data were analyzed by using student’s paired t-test, and P < 0.05 was considered significant. Result: Significant reduction in pain disability score was noted. On comparing both the groups, it was found statistically significant (P < 0.01). Conclusion: Trigger point injections with lignocaine 1% were shown to be an effective therapy for trigger point in MFPS, when assessed by the pain disability score. The improvement was not only in terms of intensity but also from the psychosocial aspect as well.
