By definition, bursitis is the inflammation of small, fluid-filled sacs which are found in places where muscles or their corresponding tendons slide across bones. Healthy bursae create a smooth, almost frictionless, gliding surface that makes normal movement painless. Subacromial Bursitis is most commonly caused by repetitive movement and / or excessive pressure or mechanical stress. Different types of it are Prepatellar bursitis, Infrapatellar bursitis Trochantaric bursitis Olecranon bursitis, and Subacromial bursitis. If you have been diagnosed with Subacromial bursitis, but do not have significant visible swelling strong Tissue Remodeling Treatments —- I.I.R.E.C-B.C.T. (Instrument Induced Remodeling of the Elastic Collagen Based Connective Tissue) are recommended.
