Myofascial cupping gained popularity after Michael Phelps used this treatment during the 2016 Olympics. The technique uses negative pressure to create a suction, which results in increased blood flow to the area to potentially assist with healing of the tissue and can have an inhibitory effect on the nervous system which can decrease pain perception. Although research of this technique is not substantial at this time, available research indicates that cupping may be beneficial in treatment of low back pain, neck pain, carpal tunnel syndrome, and knee osteoarthritis.
