Fig. 1From: Sustained acoustic medicine for the treatment of musculoskeletal injuries: a systematic review and meta-analysisA Ultrasound increases cellular proliferation, tissue regeneration, and vascularity. These mechanisms are active daily over 4Â h to upregulate healing, reduce inflammation and pain. B Ultrasound increases capillary permeability, increase nutrient exchange, oxygenation, and matrix relaxation at the site of injury, C ultrasound increases the vasodilation (vessels diameter), oxygenation, blood flow, and extends collagen fibers matrixBack to article page
