In cases of injury or overuse, the muscle loses its elasticity. Dr. Kase needed to develop a tape that would have the same elasticity as healthy human muscle. He knew from his practice that the tape would also need to stay on the skin where it was applied. He spent two years doing a lot of research relating to elasticity, adhesives and breathability. Finally, he came up with a tape that possessed the proper degree of elasticity, and that lifts the skin microscopically. From that beginning, Kinesio Tex Tape was invented. Its unique properties were based on a study of kinesiology.
