Osteopathic Manual Therapy vs Ganglion Impar Block for Chronic Coccydynia: A Randomized Controlled Trial

Chronic coccydynia is a condition characterized by persistent pain in the coccyx region that can significantly impair sitting tolerance, daily activities, and quality of life. Various conservative and interventional treatment options have been described, including manual therapy techniques and ganglion impar block. However, the comparative effectiveness of these approaches remains unclear. The aim of this randomized controlled study is to compare the effects of osteopathic manual therapy and ganglion impar block on pain intensity and functional disability in patients with chronic coccydynia. Participants will be randomly assigned to one of the two treatment groups. Pain severity will be assessed using the Numeric Rating Scale (NRS), and functional status will be evaluated with the Oswestry Disability Index (ODI) at baseline, week 3, and month 3. The results of this study are expected to provide evidence regarding the relative effectiveness of these two commonly used treatment methods and to guide clinicians in selecting appropriate management strategies for patients with chronic coccydynia.
