sam® Studies

SAM is a long-duration ultrasound treatment that biophysically activates cellular and transport kinetic activity to amplify the bodies healing response over a period of 4-8 weeks. Since the device is wearable and home-use; the patient can receive a multi-hour healing enhancement daily, which is the primary reason SAM has proven so clinically effective (duration and regularity of treatment). The medical device operates at an ultrasonic frequency/intensity/output that has been closely optimized to therapeutically maximize dose-response to the musculoskeletal system. Recommended use of the treatment is 4 hrs per day 5-7 days per week to achieve the clinical outcomes/results below:

    • Measurable Outcomes/Results (Technology Assessment): The benefits of SAM over other non-portable ultrasound devices is the capability of delivering daily ultrasound at home or in the office for up to 4 hours at a time. Traditional ultrasound is applied for 5–15 mins delivering between 2,000–5,000 Joules. The 4 hour sam® treatment can produce nearly 4 times as much (18,000 joules) as traditional ultrasound. The portable SAM device can be used at home at any time of the day and during any activity; however, traditional ultrasound requires application by a therapist in the clinical facility.

    • Measurable Outcomes/Results (Technology Assessment): Therapeutic ultrasound is an established technique for biomodulation used by physical therapists. Typically, it is used to deliver energy locally for the purpose of altering tissue plasticity and increasing local circulation. Ultrasound miniaturization in SAM allows for portable, wearable, self-applied ultrasound devices that sidestep these limitations. Additionally, research has shown that the timescale of acoustic stimulation matters, and directly affects the quality of result. This paper describes a novel, long duration approach to therapeutic ultrasound and reviews the current data available for a variety of musculoskeletal conditions.
