Myofascial Decompression “Cupping” has been used by a variety of cultures throughout time for a variety of conditions. In today’s physical therapy treatment, cupping is used to alleviate musculoskeletal pain. The cups create tension in the tissues under the cup causing capillary dilation (the bruises seen post treatment). This dilation is thought to create an immune system response by starting an inflammatory response and stimulate mechanoreceptors in the tissues. The cascade of cellular events is thought to improve tissue movement that correlates to an increase in range of motion and function to decrease pain. This technique is unique in itself as it provides the only form of decompression mobilization of myofascial tissue.
