Kinesio tape is used by athletes to treat sore or injured muscles while keeping them moving to reduce pain and speed healing. It was developed in 1979 by Dr. Kenzo Kase and works by gently lifting the skin over an injured muscle to improve blood flow and fluid movement. When applied correctly, kinesio tape supports muscle contraction and reduces pain, protects from overexertion, improves circulation to reduce inflammation, and facilitates the body's natural pain relief mechanisms. However, it must be applied correctly by a certified practitioner, as improper use could do more harm than good.
