U.S., April 24 -- ClinicalTrials.gov registry received information related to the study (NCT07547605) titled 'PRP vs PRP+Betamethasone vs Betamethasone Injection for Upper Trapezius Myofascial Pain: A 3-Arm RCT' on April 16.
Brief Summary: Myofascial pain syndrome (MPS) is a common musculoskeletal condition caused by active trigger points (TrPs) - hypersensitive, painful nodules within taut bands of skeletal muscle. The upper trapezius muscle is among the most frequently affected sites. Trigger point injection (TPI) is a widely used minimally invasive treatment for MPS refractory to conservative care. However, the optimal injectate remains debated. Corticosteroids (e.g., betamethasone) provide rapid anti-inflammatory relief but their long-...
