PNF: Proprioceptive Neuromuscular Facilitation Test – Questions & Answers (100% Correct)

PNF: Proprioceptive Neuromuscular Facilitation Test – Questions & Answers (100% Correct) PNF: Proprioceptive Neuromuscular Facilitation Test – Questions & Answers (100% Correct) PNF: Diagonal patterns and facilitation techniques - ANSWER - - the stronger muscles in the diagonal pattern facilitate the weaker ones - the brain knows nothing of the individual muscle actions - only movements ---------------------------------------------------------------- - when facilitating, incorporate all 3 planes of movement - start in lengthening range and end in shortened range PNF - ANSWER - - uses controlled sensory input - stronger muscles in diagonal patterns influence weaker ones - brain registers movement (not individual muscles) - PNF works with whole movement patterns to engage and improve motor output - a balance of antagonists are required - if an individual does not have this balance start with techniques that enhance the agonist movement PNF theory - ANSWER - - brain registers total movement - movements are spiral and diagonal - facilitation techniques are superimposed on these movement patterns - based on combination of cardinal planes of movement: flexion/extension, abduction/adduction, internal/external rotation What is PNF? (quote) - ANSWER - "A method of promoting or hastening the response of the neuromuscular mechanism through stimulation of the proprioceptors." - sensory stimulation is provided through manual contacts PNF techniques are employed through patterns of movement using: - ANSWER - -sensory stimulation - visual cues - verbal commands History of PNF: Kabat - ANSWER - - founder of PNF approach - neurophysiologist and physician - began work with poliomyelitis and MS - expanded to many disorders including orthopedic conditions - arthritis, peripheral nerve injuries, painful shoulders he found that when groups of muscles were stretched, they produce movement in diagonal patterns. This is the same for functional skills and in atheletes History of PNF: theoretical background (Sherrington) - ANSWER - 1) Irradiation - facilitation of voluntary motion by another (when one m. fires, the other mm. fire) 2) successive induction - stronger antagonists facilitates a weaker agonist (ex: trying to move triceps, the biceps can be used) 3) reciprocal innervation
