“The ZetrOZ sam ultrasound device is a very useful and efficacious modality.  The sam® unit is a long duration wearable ultrasound that we have found to be very effective for the treatment of various musculoskeletal lesions.  This unit will change the delivery of ultrasound.”

sam® Sport is an FDA-cleared bio-regenerative medical device to reduce the pain associated with tendon, ligament or muscle injuries and also accelerate the natural healing cascade. It uses ZetrOZ’s proprietary miniaturization technology to provide ultrasonic waves that penetrate five centimeters into the tissue to increase circulation, oxygen and nutrient delivery, and remove waste products, such as lactic acid, from the site of a musculoskeletal injury.  sam® Sport can deliver Sustained Acoustic Medicine with one or two applicators.

Wearable and easy-to-apply, sam® Sport 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 US and cleared for over-the-counter sale in Europe, Canada, and Asia.
