Chronic coccydynia can significantly impair daily activities, functionality, and reduce quality of life. Participants in this prospective, observational study will be evaluated during their routine visits to the pain management clinic. Evaluation of the participants will be performed using validated self-report questionnaires, including the Toronto Alexithymia Scale (TAS-20) for alexithymia, the Hospital Anxiety and Depression Scale (HADS) for mood symptoms, the Childhood Trauma Questionnaire (CTQ-33) for early life adverse experiences, the Visual Analog Scale (VAS) for pain intensity, and the 12-Item Short Form Health Survey (SF-12) for quality of life. The primary objective of the study is to determine how alexithymia relates to pain severity, duration, emotional symptoms, childhood trauma history, and overall quality of life in this specific population. The results of this pilot study may help strengthen the biopsychosocial approach in the evaluation of chronic coccydynia and optimize future multidisciplinary treatment strategies.",[24,25],"Chronic Coccydynia","Alexithymia",[27,25,28,29,30],"Chronic coccydynia","Childhood Trauma","Chronic Pain","Quality of Life","RECRUITING","2026-08-10",{"date":34,"type":35},"2026-08-12","ACTUAL",{"date":37,"type":35},"2026-03-20",{"date":39,"type":20},"2027-03",{"name":41,"class":42},"Marmara University","OTHER",1,{"id":45,"slug":46,"hasResults":11,"nctId":47,"briefTitle":48,"officialTitle":48,"acronym":4,"eligibilityCriteria":49,"healthyVolunteers":11,"sex":16,"minAge":17,"maxAge":50,"enrollmentInfo":51,"targetDuration":4,"studyType":53,"phases":54,"briefSummary":56,"conditions":57,"keywords":58,"overallStatus":31,"whyStopped":4,"lastUpdateSubmitDate":62,"lastUpdatePostDateStruct":63,"startDateStruct":65,"completionDateStruct":67,"leadSponsor":69,"locationsCount":43},"100632123","comparison-of-single--and-double-level-radiofrequency-ablation-for-chronic-coccydynia-100632123","NCT07509593","Comparison of Single- and Double-Level Radiofrequency Ablation for Chronic Coccydynia","Inclusion Criteria:\n\n* Patients with coccygeal pain lasting longer than 2 months\n* Patients who experienced significant pain relief (≥50% reduction) after a ganglion impar block performed within the last 6 months, but whose pain has subsequently recurred\n* Patients who provide informed consent to participate in the study\n\nExclusion Criteria:\n\n* Acute coccydynia (pain duration less than 2 months)\n* Patients who did not achieve significant benefit (\\\u003C50% pain reduction) from prior ganglion impar block\n* Patients with severe neurological or psychiatric disorders that impair communication or ability to follow instructions","75 Years",{"count":52,"type":20},50,"INTERVENTIONAL",[55],"NA","This study aims to compare two commonly used radiofrequency ablation (RFA) techniques for the treatment of chronic tailbone (coccyx) pain, also known as coccydynia. Chronic coccydynia can significantly impair daily activities and reduce quality of life, particularly in patients who do not respond adequately to conservative treatments. Participants in this study will be randomly assigned to receive either a single-level or double-level radiofrequency ablation (RFA) procedure targeting the coccygeal nerve pathways. These procedures are minimally invasive and are routinely performed in pain management practice. The primary objective of the study is to determine which technique provides superior pain relief and functional improvement. Patients will be followed for up to two months after the procedure, and pain intensity and quality of life will be evaluated using validated outcome measures.
