pnf patterns Flashcards
what is pnf
a learning approach used in neuromotor development to train, to improve motor function and facilitation of maximal muscular contraction
what does pnf stands for
proprioceptive neuromuscular facilitation
how does pnf works
through stimulation of sensory receptors by;
- stretch
- resistance
- traction
- approximation
- audiovisual commands
when to apply pnf
in orthopedic conditions
neurological conditions
to increase strength
flexibility
coordination and functional mobility
ICF
body function and structure
activities
participation
environmental factors
personal factors
what are the pnf approaches
+ve approach
highest functional level
mobilize potential by intense training.
consider the total human being.
use of motor control and meets learning principles.
types of sensory receptors by stimuli they respond to;
mechanoreceptors
thermoreceptors
nociceptors
chemoreceptors
sensory receptors by location
exteroceptors [superficial]
interoceptors [visceral]
proprioceptors [muscles, joints]
what does Golgi tendon organ do
protect muscle and tendon against damage by golgi tendon reflex.
what is autogenic inhibition
inhibitory interneurons activated to relax the homonymous muscle which was originally contracted
reciprocal inhibition
when afferent fibers fire stimulatory neurons and lead to relaxation of synergistic muscles and contraction of the antagonistic muscles
what is proprioception
a somatosensory feeling that gives information about the body movement and position
what structures are responsible for proprioception
cerebral cortex
cerebellum
medulla spinalis
peripheral receptors
what is a pattern
synergistic mass movement, components of functional normal motions
exteroceptive stimuli
manual contact
verbal commands
visual cues
