Proprioceptive Neuromuscular Facilitation (PNF) - PPT QUIZ!! Flashcards
What are the 4 Levels of Motor Control?
- Mobility
- Stability
- Controlled Mobility
- Skill
What is the ability to initiate movement through a functional range of motion?
mobility
What is the ability to maintain a posture or posture through contraction and tonic holding around a joint.
Stability
What is the ability to move within a weight bearing position or rotate around a long axis?
Controlled mobility
What is the ability to consistently perform functional tasks and manipulate the environment with normal postural reflex mechanims and balance reactions?
Skill
what is the developmental sequence?
pattern of movement developed from birth which can be used to relearn movements in rehab
What is muscle activation of an involved extremity due to intense action of an univolved muscle or group of muscles?
Overflow
How should verbal commands be given with PNF?
short and concise
When should resistance be given with PNF?
if goal is stability provide resistance
if goal is mobility then give less resistance
The goal of PNF is to progress patients through what stages?
Stages of Motor Control
- Mobility
- Stability
- Controlled Mobility
- Skill
what is an isotonic concentric contraction performed against resistance followed by alternating concentric and eccentric contractions with resistance?
Goal?
Agonist Reversals
Controlled mobility, skill
What is Alternating Isometrics? Goal?
Isometric contraction performed alternating form muscles on one side of joint to the other side without rest
Stability
What is Contract Relax? Goal?
As extremity reaches point of limitation, patient performs max contraction of ANTAGONISTIC muscle group for 8-10 seconds, then relax, DOING THIS ISOTONICALLY. Repeat
Mobility
What is Hold-Relax? Goal?
ISOMETRIC contraction for all muscle groups at the limiting point in ROm. Relaxation occurs and the extremity moves through new ROM
Mobility - often used for pain
What is Hold-Relax Active Movement? Goal?
Isometric performed once extremity is placed into shortened range within pattern. Upon relaxation the extremity is immediatley moved into a lengthened position of pattern with quick stretch. Pt returns to shortened position with isotonic contraciton
Mobility, used to improve initiation of muscle groups tested at 1/5 or less
What is Joint Distraction? Goal?
Manual traction provided slowly
Mobility
Normal Timing? Goal?
Performed in distal to proximal sequence. Proximal components are restricted until distal components are activated and initiate movement
Skill - trying to produce coordinated movements
Repeated Contractions? Goal?
Therapist provides quick stretch followed by isometric or isotonic contractions
Mobility - initiate a movement pattenr
Resisted Progression? Goal?
Resistance applied to the pelvis hips or extremity during gait cycle
Skill - enhance coordination, strength, or endurance
Rhythmic Stabilization? Goal?
isometric contractions of all muscles around a joint against progressive resistance
Mobility, stability
Rhythmical Rotation? Goal?
passive technique by slowly rotating an extremity around the longitudinal axis
mobility - decrease hypertonia
Slow Reversal? Goal?
slow and resisted concentric contractions of agonists and antagonists around a joint without rest between reversals
Stability, controlled mobility, skill
Slow Reversal Hold? Goal?
using slow reversals (slow and resisted concentric contractions of agonists and antagonists around a joint without rest between reversals) with the addition of isometric contraction at the end of each movement to gain stability
Stability, controlled mobility, skill
Timing for Emphasis? Goal?
Isotonic and isometric contractions to produce overflow to weak muscles
Skill
