PNF Flashcards
(60 cards)
What does PNF stand for?
proprioceptive neuromuscular facilitation
What is purpose of PNF?
these motions move in a spiral diagonal pattern of facilitation to provide for an optimal contraction
moving from lengthened to shorten position
Why does this movement pattern make sense?
because a single muscle is not solely responsible for one movement so this mimics sport of function
What are other important components of PNF?
sensory, motor and psychological
reinforces what patient can do and promotes it
What is additional benefit of PNF diagonal patterns?
enhances proper sequencing of muscle contraction distal to proximal
this promotes neuromuscular control and coordination
What are the treatment goals for PNF?
mobility, stability, controlled mobility, skill development, coordinated muscle performance (NM control)
Where should body position of PT be during PNF?
the pt should be at a diagonal, in line with the direction of the motion
face head or feet of pt
What is important to remember about communication?
hand placement, engaging a pts vision and verbal instructions are all important
What is position of hand during manual contact?
lumbrical grip
Where should you place hand on pts body?
on muscle that needs facilitation
ex: for elbow flexion hand on biceps
always on skin except for pelvis
Why is resistance important during PNF?
used to recruit motor units and strengthen the response
What is the optimal resistance?
apply just enough to have smooth controlled, pain free movement throughout the ROM, don’t hold breath
What is timing for emphasis?
PT changes normal time of sequence to emphasize a place in the range
ex: greater resistance can be placed at end ranges
What else is timing for emphasis good for?
maximum resistance can provide overflow or irradiation
goal is to increase response and stimulate action at a specific motion within a pattern
What are two other ways to provide sensory feedback?
- traction
- approximation
both are directed at joint receptors, which assist joint position
What is traction?>
seperation of two joint surfaces
assists to promote movement used as a stretch stimulus
What is approximation?
compression of joint surfaces, promotes stability and postural reflexes
directed at GTO
When would these two things be contraindicated?
if pt is having acute symptoms like pain, edema etc.
What are PNF patterns named after?
named according to their finished position of shoulder or hip
Why is the scapula so important?
because you need full control and motion but also need to generate force from it
How are scapula PNF exercises initially performed?
sidelying, edge of plinth, be sure pt has full ROM prior to initiating strength techniques
What are two types of scap D1 patterns?
anterior elevation and posterior depression
Where should PT stand for D1 scap?
stand at patients hips facing head
What muscle are involved in anterior elevation of scap?
upper trap, SA, levator scap
think of reaching into cabinet
