Objectives : The purpose of this study was conducted to find correct facilitation and clinical facilitation with proprioceptive neuromuscular facilitation (PNF). Methods : This is a literature study with books, articles, seminar note and books for PNF international course. Results : Treatment approach was changed from managements of reflex to facilitation. The facilitation will make passive or active motion. But it can not match with normal functional activities, lack of the active movement, and facilitation of musculoskeletal can interaction with environment. Conclusions : Facilitation of the Functional activities in the main therapy goal. Any necessary information, such as visual and acoustical information must be integrated. Spatial summation and temporal summation integrated also. Integrated information for the facilitation will be increased activity of alpha-motorneurons, activity of interneurons, and muscle fiber structural changes from slow twitch fibers to fast twitch fibers. Suggested facilitate goal-oriented of movements at a functional level and reduce stiffness at structural level.
