Kinesio taping involves applying a specific elastic tape to the skin over muscles and joints to support and potentially reduce pain and inflammation. The tape's elasticity allows for a full range of motion while providing support, and it's often used to aid in muscle function, reduce muscle spasms, and improve circulation. 

The tape is applied with a specific technique, often involving an anchor point, a stretch, and another anchor point. The theory is that the tape lifts the skin, creating space that allows for improved blood and lymphatic flow, which can help reduce pain and swelling. It's also believed to enhance proprioception (the body's awareness of its position in space) and potentially support weak muscles. 

Kinesio tape is commonly used for various musculoskeletal conditions, including back sprains, neck pain, shoulder injuries, and conditions like tendonitis. It's also used in sports to help with injury prevention and recovery.
