Delivering sustained acoustic medicine for effective, safe, drug-free pain relief and recovery, sam Professional uses ZetrOZ’s proprietary miniaturization technology to provide controlled-release, long duration ultrasound treatment, for up to four hours daily. No other medical technology is available to provide daily multi-hour therapeutic intervention to assist with conservative care and help injured patients get back to work sooner without surgical intervention. sam Professional works by providing continuous mechanical energy directly into tissue. Battery-powered, rechargeable, and comfortable to wear, the deep-penetrating ultrasonic energy reduces inflammatory pain and accelerates recovery of overuse injuries to tendons, ligaments and muscles, relieves chronic muscle spasms, and increases local circulation. Used successfully by a wide range of professional dancers, famous athletes, individuals who work in labor-intensive jobs, and others looking to more effectively manage chronic pain, sam Professional is available by prescription in the US. It is also cleared for sale in Europe, Canada, and Asia.
