Over time, golf is not a sport that is kind to the body. Aches and pains in the knees, wrists, back and other areas are commonplace with few remedies other than medications. Enter Oska, a wearable pain-relief device designed to reduce muscle stiffness, inflammation, ease chronic pain and increase mobility. The device, which is just slightly larger than an iPhone and can easily fit in your pocket, uses pulsed electromagnetic fields (PEMF) delivered through a unique method called sequential protocol programming -- four frequencies specifically related to muscle ease, bone repair, capillary dilation and pain reduction. By helping to release the body’s natural endorphins, Oska helps reduce pain, promoting increased range of motion.
