Abstract

Objective: To investigate whether high-energy extracorporeal shock wave therapy (ESWT) combined with conventional oral medicine as a potential novel therapeutic approach for the treatment of ankylosing spondylitis (AS)combined with sacroiliac joint bone marrow edema. Materials & Methods: 40 patients were divided into two groups and were treated with or without ESWT in combination with conventional oral medicine. A visual analog scale (VAS) score of spinal pain, as well as indicators of spinal mobility, Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) and Bath Ankylosing Spondylitis Functional Index (BASFI) scores, inflammatory index (C-reactive protein, blood cell sedimentation rate), and other indicators were compared between the two groups. The Spondyloarthritis Research Consortium of Canada (SPARCC) scoring system was used to evaluate pain and structural damage in the sacroiliac joint. Results: (1) After one month of treatment (T1), VAS, BASDAI, BASFI, and SPARCC scores were lower in both groups than at the start of treatment (T0) (P < 0.05), with greater decreases observed in the treatment group (P < 0.05). (2) Also, at T1, indicators of spinal mobility for the two groups were improved (P < 0.05). (3) ESR and C-reactive protein levels for the two groups decreased significantly at T1 versus T0 (P < 0.05). Conclusion: ESWT combined with oral medication can significantly relieve pain and improve clinical functional symptoms for patients with AS. It can also reduce sacroiliac joint bone marrow edema and control the inflammatory reaction in the sacroiliac joint, which represents a novel, effective, reliable, and safe clinical treatment therapeutic method.
