MET & PNF Flashcards
What technique is used to increase elongation via stretch and contractions?
MET and PNF
What are the physiological responses?
- Post isometric relaxation
- Reciprocal inhibition
What are the types?
PNF :
1. Contract relax
2. Antagonist contract
3. Combined
MET :
1. Post isometric relaxation
2. Reciprocal inhibition
3. Rhythmical stabilization
4. Pulsed
What are the indications?
- Muscle hypertonicity
- Decrease in range of motion
- Muscle spasms/cramps
- Muscle rehabilitation
- Neurological rehabilitation
What refers to the muscle or muscle group you aim to work out during an exercise?
Target muscle
What is a muscle that opposes the action of another?
Ex. when the triceps oppose the contraction of the flexing biceps by relaxing, the triceps would be regarded as antagonist muscle?
Antagonist muscle
What contraction occurs when tension increases, muscle length remains the same?
Isometric contraction
What contraction occurs when tension remains the same, muscles shorten and is used in movement?
Isotonic contraction
What are the indications?
- Muscle hypertonicity
- Decrease in range of motion
- Muscle spasms/cramps
- Muscle rehabilitation
- Neurological rehabilitation
How to perform Contract-Relax?
- Lengthen muscle until 1st barrier and back off slightly
- Tense the muscle for 7-10 seconds
- Stop the contraction and lengthen again
- Repeat the steps until normal resting length is obtained
How to perform Antagonist Contract?
- Passive contraction (position of ease)
- Contraction of the antagonist
- Stop contraction and bring target muscle into lengthened position
- Repeat until normal resting length is obtained
How to perform combines?
- Lengthen target muscle
- Contract target and then antagonist, both 7-10 sec
- Repeat until normal resting length
What are the effects?
- Reduces muscle tone
- Reduces muscle spasm
- Increases ROM
- Increased neurological functioning
What are the contraindications?
- Locally painful conditions
- Local acute conditions affecting the tendon
- Hypotonic or atonic muscles
- Tissue fragility
- Pathologies of connective tissue and skin lesions
