Proprioceptive neuromuscular facilitation (PNF)

Proprioceptive neuromuscular facilitation (PNF) is a physical therapy technique designed to improve neuromuscular function, flexibility, and range of motion[1][4][5][6]. It works by stimulating proprioceptors—sensory receptors in muscles and joints that provide information about body position and movement[1][7]. The approach typically combines stretching and muscle contraction (isometric or isotonic), often with assistance from a partner, to enhance strength and functional movement patterns[3][6]. PNF was developed in the mid-20th century for rehabilitation, particularly addressing movement deficits due to neurologic or musculoskeletal conditions[4][7]. It is not a receptor, transporter, or molecular target, but rather a physiotherapeutic concept that leverages neurophysiological principles like autogenic inhibition, reciprocal inhibition, stress relaxation, and irradiation to promote motor learning and functional recovery[3][5][7][8].
