Whether you are an athlete, athletic trainer or physical therapist, the PowerPlay offers benefits by combining cold and compression therapy for joint relief and muscle recovery. Technologically advanced, the PowerPlay offers alternating, intermittent, pneumatic compression applied at regular intervals to reduce swelling or improve circulation and muscle recovery. Cold therapy has been shown to be effective in decreasing pain, muscle spasms and swelling. PowerPlay takes these benefits further by adding active compression. This goes beyond mitigating pain and swelling by mimicking the body's natural muscle contractions, "pumping" edema out of the injured area, stimulating tissue healing, increasing blood flow and delivery of oxygen to the site and optimizing lymphatic drainage. PowerPlay's form-fitting, gel-filled, re-freezable joint wraps are better than ice. The non-toxic gel is malleable direct from the freezer, bringing instant pain relief with no risk of tissue damage due to overexposure to cold.
