PNF Exercises

Question 1

What is facilitative stretching?

Answer 1

Proprioceptive Neuromuscular Facilitation (PNF) is the combination of muscle contraction and stretching.

Question 2

How do you perform Contract-Relax/Hold-Relax (CR) and HR) ?

Answer 2

• Take segment to feeling of stretch, hold for 10 -30 seconds
• Have patient perform a submaximal isometric contraction for 5-10 seconds
• Have patient relax muscles
• Take segment into newly gained range, up to stretch, no pain
• Repeat/Hold
• Last stretch is held for 30 seconds

Question 3

What is the difference between CR and HR?

Answer 3

HR- The target muscle is contracted isometrically

CR- The axial rotators of the limb are allowed to contract concentrically. All other mm groups are to be contracted isometrically.

Question 4

How do you perform Agonist Contract (AC)?

Answer 4

• Patient concentrically contracts the (agonist) the muscle opposite the range-limiting muscle.
• Hold the end range position for 10 seconds
• All motion is controlled by the client and is deliberate and slow.
• Rest (Return to neutral) to avoid mm cramping
• Repeat

The only type that can be used for spasm

Question 5

How do you perform Contract-Relax-Contract (CRC)?

Answer 5

• Therapist moves segment into position of tissue resistance, hold for 10-30 seconds
• Have patient perform an 5-10 second isometric contraction of the target mm
• Relax target muscle
• Immediately concentric contract the muscle that opposes the action of the - Target / performs the range you are trying to increase (10 seconds)
• Repeat
• Hold last stretch for 30 seconds

Question 6

What are the precautions to CR?

Answer 6

The patient does not need to perform a maximal isometric contraction. It should be sub-maximal to avoid Valsalva Maneuver and a spike of blood pressure.

Question 7

What are the precautions to AC?

Answer 7

Avoid full range, ballistic movements when performing concentric contractions of agonists.

Rest after each repetition to avoid cramping of agonist.
