Bilateral Erector Spinae Plane Block for Myofascial Pain Syndrome

Study Overview
=================
Brief Summary
-----------------
The investigators aimed to evaluate the effectiveness of bilateral erector spina plane block application in myofascial pain syndrome.

Detailed Description
-----------------
The investigators aimed to evaluate the effectiveness of bilateral erector spina plane block application in myofascial pain syndrome by comparing trigger point injection. Group 1 only one time erector spinae plane block and group 2 once a week total three times trigger point injection. Before the application, one week after application and one month after first application the investigators aimed to compare pressure pain threshold with algometer, visual analog scale score, short form-36 score, neck disability index score, beck depression scale score for the two groups. Each group has 30 participants, total 60 participants included this study. The investigators planned to show that bilateral erector spinae plane block can be used as an effective and safe method in the treatment of myofascial pain syndrome, since it is easier to apply than other invasive procedures used in the treatment and has a very low complication profile.

-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Comparison of the effectiveness of the two interventions (trigger point injection versus Erector spinae plane block) assessed by Visual analog scale (VAS): | The classic interventional treatment of myofascial back pain is trigger point injection. In addition, erector spina plan block has been applied in recent years as an interventional procedure that provides analgesia in the same region and is thought to have a long duration of action. Visual analog scale (VAS): Using a ruler, the score is determined by measuring the distance (mm) on the 10-cm line between the no pain anchor and the patient's mark, providing a range of scores from 0-100. A higher score indicates greater pain intensity. | Baseline |
