PNF Flashcards
Example of some receptors are?
Sight Touch Muscles Tendons - Golgi Ligaments
Where does all sensory info end up in the brain?
Parietal lobe in somatosensory cortex
Sensory information stimulates motor activity in what two ways…
Short term - causes a response
Long term - becomes automatic from practice
What does rehabilitation of movement require?
Specific to movement wanting to be restored
Awareness of changing environment
Sensory feedback
What are the types of sensory feedback?
Knowledge of results Knowledge of performance Motivation Reinforcement Information
Proprioception
Neuromuscular
Facilitation
What does each part involve?
P - using sensory info for knowledge on position and movement t
N - using nerves and muscles
F - making movement an easy process
What principles are PNF reliant on?
All humans have existing potential
Treatment is positive
The goal is to achieve the highest level of function
Movement occurs in patterns and diagonals
Why is PNF used in diagonals and rotation?
Because muscles lay in diagonals and spirals
Because functional movement is performed in diagonals
What is the flexor PNF pattern?
Flexion
Abduction
LR
What things do you change about PNF to make is specific?
Patterns
Procedures
Techniques:
- strength- slow reversals or repeated contraction
- lengthening - hold and relax or contract and relax
What are slow reversals?
Active motion changing from one direction to another without relaxing
What are repeated contractions?
Repeating a pattern several times with maximum resistance
What is contract and relax?
Resisted isotonic contraction of muscles without pause - once ROM has been achieved you immediately do the opposite way
What is hold and relax?
Resisting isometric contraction followed by relaxation
What is proprioception? And what does it require?
Stimuli produced and perceived in the body relating to position and movement
Requires sensory input from intero and exteroceptors
