Integrated Multimodal Therapy for Postural Orthostatic Tachycardia Syndrome in a Patient with Spinal Cord Injury: A Clinical Case Report

Background Postural Orthostatic Tachycardia Syndrome (POTS) involves excessive heart rate increase upon standing, exacerbated by autonomic dysfunction. Spinal cord injury (SCI) disrupts autonomic regulation, complicating POTS management. This case report explores a multimodal intervention for a 54-year-old male with C5-level SCI and worsening POTS symptoms.  Case Presentation The patient, 18 months post-traumatic SCI, presented with severe dizziness, palpitations, and fatigue exacerbated by upright postures. Vital signs showed increased heart rate on standing with stable blood pressure. Diagnostic tests confirmed POTS with autonomic dysfunction, ruling out orthostatic hypotension and cardiac arrhythmias.  Management A multidisciplinary approach included pharmacological management (fludrocortisone, baclofen, clonazepam, Metoprolol), diet and fluid adjustments (increased water intake, small frequent meals), and physical therapy. Physical interventions comprised tilt table training, muscle contractions, negative pressure breathing, and psychosocial support (progressive muscle relaxation, mindfulness, sleep management).  Results Post-intervention, the tilt table test showed no significant heart rate increase. The Orthostatic Intolerance Questionnaire scores improved from 37 to 12, indicating enhanced orthostatic tolerance. PROMIS scores showed better general health and reduced pain, while anxiety and depression scores improved from abnormal to near-normal levels. These outcomes reflect significant advancements in managing POTS and overall well-being.  Conclusion The multimodal intervention effectively managed POTS in the context of SCI, highlighting the importance of a tailored, integrative approach. This case underscores the need for further research to refine multimodal strategies for complex autonomic disorders.
