Abstract: (39 Views)
Introduction: Piriformis syndrome is a neuromuscular condition characterized by compression or irritation of the sciatic nerve by the piriformis muscle or adjacent structures. Various conservative treatment modalities have been proposed, including extracorporeal shockwave therapy (ESWT) and image-guided corticosteroid injections. This systematic review aimed to compare the effectiveness of ESWT and guided corticosteroid injections in improving pain and functional outcomes in patients with piriformis syndrome.
Methods: A systematic review was conducted by searching English- and Persian-language studies published up to 2025 in PubMed/MEDLINE, Web of Science, Scopus, SID, Magiran, Noormags, and Google Scholar. Studies evaluating the effectiveness of ESWT and guided corticosteroid injections in patients with piriformis syndrome were screened according to predefined inclusion and exclusion criteria. Eleven eligible studies involving a total of 576 participants were included in the review. The review protocol was registered in PROSPERO (CRD420251242461).
Results: The findings demonstrated that both ESWT and guided corticosteroid injections were effective in reducing pain intensity and improving functional outcomes and quality of life in patients with piriformis syndrome. Across the included studies, the two treatment modalities showed comparable clinical effectiveness, with no substantial differences in short-term outcomes. Improvements were generally maintained for up to three months following treatment.
Conclusion: Current evidence supports the clinical equivalence of ESWT and guided corticosteroid injections for the management of piriformis syndrome. Both interventions effectively reduce pain and improve quality of life. However, ESWT offers the advantages of being noninvasive and having a favorable safety profile, making it an attractive first-line treatment option, particularly for patients with contraindications to corticosteroid injections or concerns regarding invasive procedures.
