Contribution of Erector Spina Plane Block to Analgesia for Myofascial Pain Syndrome

Contribution of Erector Spina Plane Block to Analgesia Combined With Ultrasound Guided Trapezius Muscle Injection for Myofascial Pain Syndrome

Myofascial pain syndrome is a common chronic disease characterized by pain and tenderness in one or more muscle groups. It is characterized by myofascial trigger points that are felt as a band or a nodule harder than normal consistency located in the muscle. Myofascial trigger points are developes as a result of muscle injury ; this can be acute trauma caused by sport injury, accident, or chronic muscle overuse by repetitive occupational activities, emotional stress or poor posture. Trigger point injection is the application of low dose local anesthetic drug into the trigger point.Its main purpose is to weaken the trigger point caused by muscle spasm.However, it may reduce pain partially or have a short duration of action, so it may need to be repeated several times at regular intervals.Trigger point injection can reach trigger points in superficial muscles With the erector spina plane block technique, more effective and long-term pain treatment can be achieved by reaching deeper trigger points. With this hypothesis, we aimed to investigate the contribution of the erector spina plane block to trigger point injection in the treatment of myofascial pain.

Patients with myofasial pain syndrome will randomized into two group. TMI group will receive ultrasound guided trapezius muscle injection two times with one week interval. ESPB group in the 1th week will receive ultrasound guided trapezius muscle injection and in the 2nd week ultrasound guided erector spina plane block will receive. Pain severity of the patients will evaluate by visual analog scale. Datas will obtaine before (week 0) and after (week 1,2,3,4) the injections.

One physician who will be blind will examinade all patients for eligibility and will valuate the outcome measures although the physician who will performe all injections will not be blind.
