PNF stretching Flashcards
1
Q
What does PNF stand for
A
Proprioceptive Neuromuscular Facilitation
2
Q
Muscle spindles
A
Provides information to CNS about how fast and how far a muscle is being stretched
3
Q
Golgi tendon organs
A
Activated when there is tension in a muscle (detect levels of tension)
4
Q
How to perform PNF (7 steps)
A
- Passive stretch
- Muscle spindle- leg is stretched to max
- Activated stretch reflex (contract)
- Isometric- 10sec hold
- Activating GTO- Release tension
- This overrides stretch reflex- Autogenic inhibition
- Passive stretch- Increases range of movement
5
Q
What is the CRAC technique
A
Contract
Relax
Antagonist
Contract
6
Q
Definition Autogenic Inhibition
A
Where there is a sudden relaxation of the muscle in response to high tension. The receptors involved in this process are Golgi tendon organs
7
Q
Definition of a Motor neurones
A
nerve cells that transmit the brains instructions as electrical impulse to the muscles
