PNF stretching is a type of stretching that involves contracting and relaxing the muscles being stretched. This technique helps to improve flexibility and increase range of motion. PNF stretches are typically performed with a partner or trained professional, who assists in the stretching process.
In sports massage, PNF stretches can be used to help athletes improve their muscle flexibility and prevent injury. In  a therapeutic massage, PNF stretches can help relieve tension and improve mobility in  stubborn muscles during a  therapeutic massage . In children's massage, PNF stretches can help improve flexibility and range of motion in kids with muscle tone issues or motor deficits.
