Percussion massage, often referred to as percussion therapy, is a technique where the head of a massage device delivers rapid and rhythmic strokes perpendicularly into the muscle tissue. This movement resembles tapping and penetrates deep into the muscles and fascia, which are the connective tissue coverings of muscles. The goal is to relieve muscle tension, improve blood circulation in the affected area, and promote regeneration. Users can typically adjust the speed and intensity of the strokes, thereby customizing the massage to their needs. The devices often feature various attachments for targeted massage of specific muscle groups.
