Proprioceptive neuromuscular facilitation is a common practice implemented to enhance the range of motion throughout the neurological and musculoskeletal aspect of the body, though little research has been performed to evaluate theories behind it. The aim of this manuscript is to evaluate possible mechanisms, proposed theories, physiological effects and techniques that fall within its scope. The manuscript incorporates various maneuvers implemented within this technique that aim to imitate the effects of facilitation in order to increase the response of neuromuscular mechanism, various types...
