Ultrasound-guided Botulinum Toxin Injection for Intractable Abdominal Spasms in Spinal Cord Injury: A Case Report

A 43-year-old patient with C4 tetraplegia experienced severe, treatment-resistant spasms of the rectus abdominis muscle that failed high-dose oral baclofen therapy. Ultrasound-guided botulinum toxin injection into the affected abdominal muscle resulted in significant reduction in spasm frequency and severity, with improved comfort and quality of life, suggesting this targeted approach may be a safe alternative for focal abdominal spasticity in selected spinal cord injury patients.
