Most manual therapy utilized in physical therapy is very compressive, in nature, such as Soft Tissue Mobilization, Myofascial Release, and Joint Mobilization.
Myofascial Decompression (MFD) or ‘cupping,’ has been around for thousands of years. It works in the decompression of adhesions; reducing inhibition of fluids and nutrient exchange. During MFD, the negative pressure created by the suction draws the skin and fascial layers away from the midline of the body. This decompression alters blood flow and metabolic exchange within the tissues. It is effective in decreasing stiffness and pain, improving tissue health, and increasing mobility.
Almost everyone, athletes included, is left with circular marks from the negative pressure of the cups. See the chart below for a description of what each color or pattern represents.
