Brief Summary

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.

Conditions

Ankylosing Spondylitis

Outcome Measures

Primary Outcomes (1)

• Bath Ankylosing Spondylitis Disease Activity Index

  Based on the patient's symptoms over the past week, an assessment is conducted through six questions. The first five questions are scored using a Visual Analog Scale (VAS, 0-10 points). The calculation formula is generally expressed as: BASDAl = 0.2x(A+B+C+D+(E+ F)/2) Where: A represents the degree of fatigue/tiredness; B represents the degree of pain in the neck, back, or hips; C represents the degree of pain/swelling in other joints; D represents the level of discomfort from bodily tenderness or pressure pain; E represents the severity of morning stiffness; F represents the duration of morning stiffness (converted to a 0-10 score). BASDAI 24 indicates high disease activity, while a score \<4 suggests lower disease activity.

Study Arms (2)

Treatment Group

EXPERIMENTAL

All subjects were enrolled at week 0 and, after completing baseline assessments, received acupotomy treatment once per week for a total of four sessions over the initial three-week period. The core intervention for the treatment group (acupotomy group) involved ultrasound-guided precise release: first, the target vertebra with the most significant lesions was identified through palpation and ultrasound imaging, after which the acupotomy was accurately guided in real-time via ultrasound to the interspinous points (located at the interspinous ligaments) and paraspinal points (located at the intertransverse ligaments) of the target vertebra and adjacent vertebrae for release.

Procedure: Acupotomy

Control Group

SHAM COMPARATOR

The control group (sham acupotomy group) strictly replicated all preliminary procedures of the treatment group, including exploration, ultrasound localization, and local anesthesia. However, the acupotomy needle only pierced the epidermis without performing any release operations in the deeper tissues, thereby maintaining blinding and assessing the specific effect of the acupotomy therapy.
