An FDA-cleared, bioregenerative medical device that reduces the pain associated with tendon, ligament, or muscle injuries and also accelerates the natural healing cascade. It provides ultrasonic waves that penetrate 5 cm into the tissue. This increases circulation, oxygen, and nutrient delivery, and helps to remove waste products, such as lactic acid, from the site of a musculoskeletal injury. Wearable and easy to apply, this device is used by a wide range of professional and collegiate athletes, as well as "weekend warriors" and recreational enthusiasts. It is available by prescription in the USA.
