Comparing Efficiencies of Local Anesthetic Injection and Photobiomodulation in the Treatment of Fibromyalgia Syndrome

Abstract

Aim. This study aimed to evaluate the efficiencies of local anesthetic injection and photobiomodulation methods in the treatment of fibromyalgia syndrome.Patients and Method. A total of 40 patients between 20 to 60 years-of-age and diagnosed with fibromyalgia syndrome according to the diagnostic criteria of the American College of Rheumatology were included in the study. Patient were randomized into two study arms, of which the first group received prilocaine injection to the tender points on the shoulder girdle, and the second group of patients received photobiomodulation by low-dose laser application. Also, both study groups received an education program that included postural and stretching exercises. The number of tender points, morning stiffness, sleep quality, muscle spasms, and disability parameters were compared using likert scale, pain levels were compared using visual analog scale (VAS), general status was compared using Fibromyalgia Impact Questionnaire (FIQ), and psychological status were compared using Beck Depression Inventory (BDI). Results: Both methods showed statistically significant improvements. Additionally, regarding the improvement levels, local anesthetic injection decreased the number of trigger points, and improved muscle spasm and disability levels more. On the other hand, low-dose laser therapy improved the morning stiffness, sleep quality, and Beck depression scale scores more. Conclusion: According to our results, both methods were efficient for the treatment of fibromyalgia syndrome. Individual patient assessment, and selecting the method that most fits the patient needs is crucial for successful outcomes.
