Ab1579-HPR Comparison of Trigger Point Injection Application Methods in Myofascial Pain Syndrome in Patients With Fibromyalgia Syndrome

Background: Treatment of Fibromyalgia Syndrome (FMS) aims to inactivate the trigger point, relieve pain and eliminate aggravating factors. Recently, the use of ultrasound (US) has been recommended to minimize the complications that may be encountered in trigger point injection and to perform an effective injection. Objectives: This study was aimed to compare the efficacy of blinded and US-guided trigger point injection into the trapezius muscle in individuals with FMS. Methods: 75 patients with FMS were included in the study. After the patients were randomly divided into two groups, one group underwent US-guided trigger point injection. The second group was practiced blinded trigger point injection. Both groups were given the same home exercises (stretching and posture exercises related to the trapezius and pectoral muscles). Patients were re-evaluated at 1 month after treatment to assess the efficacy of the treatments. Fibromyalgia Impact Questionnaire (FEA), Visual Analog Scale (VAS), Beck Anxiety Inventory (BAI) and Neck Disability Index were used to evaluate function, pain, anxiety and disability of neck, respectively. Results: The study was completed with 60 patients. There was no statistically significant difference between the demographic variables of the two groups (p>0.05). When US-guided and blinded trigger point injections were compared, a significant difference was observed in neck disability (p=0.041). Significant differences were observed in both groups in all parameters evaluated in pre and post-treatment evaluations (p<0.05). Conclusion: USG-guided trigger point injection had positive effects on pain, function, anxiety and neck pain in FMS patients. USG-guided trigger point injection may be recommended in clinics to improve symptoms of the disease. REFERENCES: [1] Taheri N, Rezasoltani A, Okhovatian F, Karami M, Hosseini SM, Mohammadi HK.
