If you watched any of the 2012 London Olympics then there is no doubt you saw athletes covered in a variety of different colored tape. It was easiest to see on the beach volleyball athletes but it was on athletes in most every event.
It is called Kinesio tape and has many functional uses none of which are enhanced by the myriad of colors that it is available in. Our therapists have taken the Kinesio Taping course and are now using it to aid in the decrease of swelling, bruising and pain. It is also able to facilitate or inhibit muscle function depending on the mode of application.
