SCENAR is an advanced form of electrotherapy and may be effective in treating acute and chronic pain. SCENAR therapy functions on two physiological principles: that the body has its own healing capabilities and that it is continually employing processes of self-regulation to maintain health. SCENAR® is a hand-held, therapeutic pain relief device (FDA 510(k)), that is used to reduce acute and chronic pain, improve blood circulation, perform muscle stimulation, and provide functional restoration and systemic improvement. SCENAR® therapy is effective in reducing pain and sustaining pain relief, reducing swelling and inflammation, and reducing muscular spasm and as a result giving improved function, flexibility, and accelerated healing time.
