Overview

This study employs a randomized controlled trial methodology to systematically evaluate the efficacy and safety of a modified acupotomy technique in the treatment of ankylosing spondylitis. Through ultrasound-guided localization, the operative sites are assessed to clarify the improvement effect of the modified acupotomy on disease activity in AS patients. The aim is to enhance the clinical outcomes of AS, provide evidence-based medical support for acupotomy treatment of AS, and improve the diagnosis and treatment standards for the condition.
