Kinesiology tape
 
Kinesiology tape is a thin, flexible tape that was developed to aid muscle movement and enhance athletic performance. It is often used to relieve pain, reduce swelling and inflammation and provide support to joints and muscles. 
The elasticity, or stretchiness, of kinesiology tape allows for movement. This makes it different from the more rigid rehabilitation tape or support adhesives that have no stretch to them. Those are used to keep muscles and joints from moving and provide support after a sports-related injury, and for people who have conditions that make it difficult to activate muscles or control muscle contraction.
