Proprioceptive neuromuscular facilitation
PROPRIOCEPTIVE NEUROMUSCULAR FACILITATION
DEFINITION A motor learning approach used in neuromotor development training to improve motor function and facilitate maximal muscular contraction.
According to Kabat (1951) "The basis of the PNF philosophy is the idea that all human beings, including those with disabilities have untapped existing potential.
PNF BASIC PROCEDURES FOR FACILITATION
Patterns Of Motion
Normal Motor activity occurs in synergistic & functional patterns of movement. PNF technique are "spiral & diagonal" in character and combine motion in all 3 planes i.e. flexion/extension, abduction/adduction and rotation.
Extremities patterns are named according to the movement occurring at the proximal joint or by diagonal(antagonist patterns are make up the diagonal).
UPPER EXTREMITIES
D1 Flexion- Flexion,Adduction,External Rotation.
D1 Extension-Extension,Abduction,Internal rotation.(Antagonist pattern of D1 flexion).
D2 Flexion- Flexion, Abduction, External Rotation.
D2 Extension- Extension,Adduction,Internal Rotation.(Antagonist pattern of D2 flexion).
LOWER EXTREMITIES
(D1 Flexion of Lower Extremities is similar to Upper Extremities pattern).
D1 Flexion- Flexion,Adduction,External Rotation.
D1 Extension- Extension,Abduction,Internal Rotation.(Antagonist pattern of D1 flexion).
D2 Flexion- Flexion,Abduction,Internal Rotation.
D2 Extension- Extension,Adduction,External Rotation.(Antagonist pattern of D2 flexion).
HOW TO PERFORM UPPER EXTREMITIES PNF PATTERN
D1 Flexion
Starting Position
Patient Position- Extension/abduction/internal or medial rotation of the shoulder with pronation of the forearm,extension with ulnar deviation of the wrist,extension of the fingers,extension and abduction of the thumb.The therapist ensure that patient near to the side of plinth to enable the arm to be taken to extension. The patient's arm should be abducted around 20°-30° from the side of the body.Care must be taken that patient's finger are in fully extension before the movement begins.
Therapist Stance- Therapist stands at patient's upper arm level in Lunge position facing towards the patient's feet & with his weight on her front right foot & parallel with proposed line of movement.During the arm's movement of patient,therapist transfers his weight from the front foot to the back foot rotating so that he can watch the movement throughout the movement pattern.
Grip- Therapist grasp the patient's right palm approaching from palm approaching from radial side. He uses the lumbrical grip ensuring that extensor surface of patient's hand does not touch.Fingers of right hand placed on flexor aspect of patient's wrist approaching from ulnar side.
Commands- Therapist prepares patient for the movement by saying 'now' & then follows this with command like"grip my hand, pull up and across the face.
Movements- Flexion of fingers, particularly the little & ring fingers,adduction & flexion of thumb, flexion of wrist towards the radial side with supination of the forearm,flexion,adduction & lateral rotation of the shoulder joint,while scapular joint is in rotation,elevation & protraction.Movement is initiated by rotary component.Movement then occurs at distal joints followed in succession by more proximal joints until whole extremities is moving.
