PNF Flashcards
what is the proprioceptive part of PNF?
having to do with any of the sensory receptors that give info concerning mover and position of the body
what is the neuromuscular part of PNF?
involving the CNS, nerves, and muscles
what is the facilitation part of PNF?
making movt easier
normalizing movt
strengthening/augmenting movt
who developed PNF first?
Dr. Herman Kabat and PT Maggie Knott
who later added the task emphasis to PNF?
Dorothy Voss
t/f: movts in PNF are patterns set up to be similar to normal movt
true
t/f: PNF movts are usually in a cardinal plane
false
PNF is directed at improving what?
functional performance and coordinated patterns of movt
PNF patterns emphasize move in ______ and _____ rather than straight planes
rotation, diagonals
t/f: neuro PNF emphasizes proximal trunk, functional activities, and “developmental” postures
true
what developmental postures are used in PNF?
rolling, prone on elbows, quadruped, kneeling, half kneeling, modified plantigrade, standing and gait
PNF patterns resemble what patterns?
patterns used in normal functional activities
describe the PNF patterns generally:
spiral and diagonal, combining motions in all 3 planes (flex/ext, add/abd, transverse rotation)
PNF techniques incorporate what motor learning principles?
practice, repetition, visual guidance, and verbal cues
what is the point of visual guidance in PNF?
it enhances pt awareness of where there limbs are in space
t/f: facilitation techniques are proprioceptive and used to facilitate movement when it’s absent or severely disordered
true
what are the hallmarks of PNF?
moving in diagonal planes
spindle activation
sensory input
max/graded resistance
timing
verbal cues
visual cues
what provides spindle activation in PNF?
quick and prolonged stretch
what provides sensory input in PNF?
lumbrical grip
what are the indications for PNF?
relaxation
initiation of movt
education/learning a motion
increased stability
applied throughout the ROM
facilitation-inhibition
superimposed on contraction
change rate of motion
increased strength
increased ROM
increased coordination and control
what disorders/injuries/diseases may result in instability?
SCI, down syndrome, CP, R CVA (lateropulsion), cerebellar injury, shoulder injury
what ataxia would result from injury to the central/spinal cerebellum?
trunk ataxia
what ataxia would result from injury to the outer lobes of the cerebellum?
limb ataxia
what ataxia would result from injury to the floculonodular lobe of the cerebellum?
visual ataxia
