sam Sport – Clinical Evidence

Clinical Trial demonstrates that patients with tendinosis of the elbow or Achilles, treated daily with sam® Sport for four hours per day, experienced a 70% reduction in pain after six weeks of treatment. Grip strength also increased by 17% in patients with elbow tendinosis, demonstratingrecovery of the injured tendon.

Patients treated with sam® Sport on a daily basis recover faster after a tendon injury.

National Sports Medicine Experts Discuss sam® Sport as a Non-Surgical Soft-Tissue Treatment for Athletes

Accelerated Muscle Recovery 1

Athletes treated with a single, multi-hour sam® Sport therapeutic session experienced a 20% reduction in lactate accumulation in the blood, following strenuous exercise, when compared to the control group. When the strength and function of the treated muscles were then tested, greater muscle performance was observed, as measured by Average Power and Peak Torque. These effects may result from the ability of sam® Sport to stimulate local circulation to active muscles.

Osteoarthritis—Pain Relief and Function 1,2

Pain Relief Grows with Regular Therapy and Joint Function Improves
Osteoarthritis 1,2,3

Ultrasound therapy, according to the Cochrane Review, is clinically effective and covered under most insurance plans for Osteoarthritis pain management. In multiple clinical trials, sam® Sport daily wearable multi-hour ultrasound therapy has been proven clinically effective on reducing pain and improving function of patients suffering from moderate to sever Osteoarthritis. When applied  during normal daily activity, patients experience 39% to 51% pain reduction in the treated joint.

In one randomized placebo controlled clinical trail on knee Osteoarthritis, treatment of patients with moderate- to severe pain with sam® Sport (four hours per day, daily for six weeks) resulted in a 39% reduction in pain levels, compared to only a 17% decrease in pain in the control group (p<0.05).

Trapezius Muscle Spasm—Pain Relief 1

Patients Report Pain Reduction
Immediately Within Treatment Sessions
Trapezius Muscle Spasm 1

“My sore back was killing my golf game. After using the sam® Sport for about a week, my club head speed returned, my distance off the tee greatly improved, and I am hitting more greens and overall playing a great deal better. I was comfortable using the device the moment I opened the box, and I am now able to play on consecutive days without the debilitating pain I use to have.”

Kellen Winslow Sr.
Pro Football Hall of Fame (San Diego Chargers)
Patients with acute pain caused by trapezius muscle spasms experienced immediate pain relief from a single, one-hour sam® Sport treatment session. They reported a 15% improvement in the severity of pain they were experiencing, approximately twice the effect observed in the control group.

How sam® Sport Works 1

How Sam Sport WorksThe Biological Effects on Soft-Tissue:

sam® Sport is clinically proven multi-hour therapy to activate the following mechanisms of action in tissue to facilitate soft-tissue recovery:

  • Increase blood flow and oxygenated hemoglobin
  • Stimulate angiogenesis and new blood vessel development
  • Increase collagen lay-down in connective tissue
  • Increase nutrient transfer to injured tissues to aid in recovery

How Deep and Broad the Therapeutic Effect Covers:

sam® Sport provides continuous ultrasonic-waves that penetrate up to 5-cm into the tissue and approximately the diameter of a Baseball: 3MHz and 0.65 Watts/Applicator (Energy Density 0.132 Watts/cm2 per Applicator).
