During the course of physical activity & exercise the muscles tendons and ligaments of the body may over-extend or over-contract outside of their normal range. When this happens recovery slows and the tissue becomes inflamed swollen or stiff. As a result the space between the skin and muscle compresses restricting lymph and blood flow and causing pain or discomfort.KAPTRON kinesio tape microscopically lifts skin away from the muscle alleviating pain and decompressing the space â improving blood flow & lymphatic drainage to speed up recovery time.
