One PNF technique that Black says can trigger the reflex is commonly called “hold-relax.” This involves:
- Putting a muscle in a stretched position (also called a passive stretch) and holding for a few seconds.
- Contracting the muscle without moving (also called isometric), such as pushing gently against the stretch without actually moving. ...
- Relaxing the stretch, and then stretching again while exhaling. ...
How does hold-relax PNF stretch work?
The activity in the quadricep causes reciprocal inhibition of the hamstrings allowing for a greater stretch. The hold-relax PNF stretching technique is used to facilitate the relaxation of muscles to gain range of motion. This method uses an isometric contraction rather than an isotonic one.
What is holdhold relax PNF?
Hold Relax (HR): It is one of PNF Techniques usually performed at a position of comfort and below a level that causes pain. Strong isometric contraction of the restricting muscles (antagonists) is resisted, followed by voluntary relaxation, and passive movement into the newly gained range of the agonist pattern.
How do you activate the PNF reflex?
Hold-relax One PNF technique that Black says can trigger the reflex is commonly called “hold-relax.” This involves: Putting a muscle in a stretched position (also called a passive stretch) and holding for a few seconds. Contracting the muscle without moving (also called isometric), such as pushing gently against the stretch without actually moving.

How do you perform PNF?
PERFORMING A PNF STRETCH To begin, the muscle group to be stretched is positioned so that the muscles are stretched and under tension. Next, the individual then contracts the stretched muscle group for 5 – 6 seconds while a partner, or immovable object, applies sufficient resistance to inhibit movement.
What is PNF training used for?
Proprioceptive neuromuscular facilitation (PNF) is a stretching technique that can improve your range of motion. Many therapists use PNF to help people regain their range of motion after injury or surgery. However, it can also be used by athletes and dancers to improve their flexibility.
What does PNF mean in physical therapy?
Proprioceptive Neuromuscular Facilitation (PNF) is a more advanced form of flexibility training. PNF involves both stretching and contracting (activation) of the muscle group being targeted in order to achieve maximum static flexibility.

PNF stretching can improve your range of motion, or ROM. It can also boost your muscle flexibility and strength. Increase ROM. By stretching or lengthening the muscle spindles and Golgi tendon organs (GTO) through PNF, you can increase your ROM.
How to do PNF?
When doing PNF exercises, you typically: 1 Stretch a muscle group. 2 Contract this muscle group against resistance while it’s still in the stretched position. 3 Stretch the muscle group again.
Why do people use PNF?
Many therapists use PNF to help people regain their range of motion after injury or surgery. However, it can also be used by athletes and dancers to improve their flexibility.

So this was the detailed and studies based article about PNF (Proprioceptive Neuromuscular Facilitation). Flexibility and range of motion are key for athletes and sportspersons. Also for bodybuilders and gym freaks, doing stretching exercises is very important to maintain flexibility.
Why is stretching important?
Stretching is an important aspect of physical exercise. It improves flexibility and helps in preventing injuries during sports and exercises. There are various types of stretching techniques: dynamic stretching, static stretching, ballistic, and PNF stretching.
How to perform PNF stretching?
isometric contraction. However, there are proper ways to do that. Hence, to perform PNF stretches, it is better to have a partner or therapist. Here are the techniques of PNF stretching. 1. Hold-Relax.
How long should you hold a stretch?
Stretch and hold: Putting a muscle in a stretched position and hold that stretch for some time (about 10 seconds). This can be called a passive stretch.

Who developed the PNF technique?
Developed in the 1940s, PNF Techniques are the result of work by Kabat, Knott and Voss. They combined their analysis of functional movement with theories from motor development, motor control, motor learning and neurophysiology.
What is CR in PNF?
Contract Relax (CR): It is one of PNF Techniques usually performed at a point of limited ROM in the agonist pattern. Strong, small range isotonic contraction of the restricting muscles (antagonists) with emphasis on the rotators is followed by an isometric hold. The contraction is held for 5-8 seconds and is then followed by voluntary relaxation and movement into the new range of the agonist pattern. Movement can be passive but active contraction is preffered.
When did PNF start?
During the 1960s, the physical therapy departments of several universities began offering courses in PNF and by the late 1970s PNF stretching techniques began to be used by athletes and other healthy people for more flexibility and range of motion. Terms about muscle contraction are commonly used when discussing PNF.
Who invented the PNF?
PNF History. In the early to mid 1900s physiologist Charles Sherrington popularized a model for how the neuromuscular system operates. Irradiation is when maximal contraction of a muscle recruits the help of additional muscle flexibility. Based on that, Herman Kabat, a neurophysiologist, began in 1946 to look for natural patterns ...
What reflex causes a muscle to contract when its tendon is pulled with too much force?
He knew of the myostatic stretch reflex which causes a muscle to contract when lengthened too quickly, and of the inverse stretch reflex, which causes a muscle to relax when its tendon is pulled with too much force. He believed combinations of movement would be better than the traditional moving of one joint at a time.
What is PNF in rehab?
The pioneers’ group effort in rehab led to the practice of PNF, which focused attention on resistance, stretch reflex, and manual contacts to improve muscle function in activities of daily living. At its core, PNF is just as useful today as it was when Kabat and Knott developed it.
What is the most effective PNF stretching technique?
Hold-relax- agonist-contract. Using hold-relax with agonist contraction should be the most effective PNF stretching technique as it’s a combination of autogenic inhibition and reciprocal inhibition. Hold-relax-agonist-contract has three distinct phases. The first two are the same as regular hold-relax stretching.

Proprioceptive neuromuscular facilitation, or PNF, is thought to be a powerful tool when it comes to the treating problems in the joints and muscles. It’s a type of passive stretching among several types of stretching
Why is it important to use PNF?
When employing PNF stretching techniques it is important for both the “stretcher” and the “stretchee” to understand that maximum force and contraction are not necessary to create a response in your body. You can (and should!) use PNF safely and effectively with low level contractions.
How does contract relax work?
To perform contract-relax stretching, the partner takes the joint involved in the stretch through its full range of motion. Resistance is applied in the direction of a concentric, or shortening, contraction. Basically, you’re moving through the range generated by normal action of the muscle being stretched.
What planes of motion are used in PNF?
Although true PNF always involves very specific hand placements that direct the movements, the techniques have been extrapolated to basic planes of motion over the past several decades, such as the sagittal and frontal planes.
How many studies have met inclusion criteria but only one of them measured hamstring length using the clinically accepted technique?

What is hold relax?
The hold-relax method of PNF stretching is facilitated by the golgi tendon organ to allow a reflexive relaxation of the muscle. It can be done individually or with assistance from a trainer or physical therapist.
What is a PNF pattern?
PNF patterns of movements were developed because all normal coordinated human movements occur in spiral or diagonal motions. Muscular contractions are strongest and most coordinated during these diagonal patterns of movement. These diagonal patterns involve rotation of the extremities and require core stability. Muscular contraction is also enhanced through irradiation and there is optimal facilitation of the stretch reflex in a synergistic muscle group during movements within these patterns of movement. (2)
How to use PNF?
The hold-relax PNF stretching technique is used to facilitate the relaxation of muscles to gain range of motion. This method uses an isometric contraction rather than an isotonic one. To achieve this the limb is place in painfree range and an isometric contraction is sustained. The limb is then moved into the new range. The hold-relax method of PNF stretching is facilitated by the golgi tendon organ to allow a reflexive relaxation of the muscle. It can be done individually or with assistance from a trainer or physical therapist. The danger of the hold relax PNF stretching technique is that with this inhibition of muscle activity, it may predispose an athlete to injury if done prior to an athletic event.
What is contract relaxation?
The golgi tendon organs lie in the tendon of a muscle that mediate the stimulation of inhibitory interneurons in the spinal cord that cause relaxation of that muscle's motor neuron.
What is resistance applied to?
resistance - resistance applied to a muscle contraction will facilitate a smooth motor response through optimal muscle contraction and relearning. The type and degree of resistance varies to achieve the appropriate motor response.
What is the role of the Spindle in PNF?
Neuromuscular Mechanisms. PNF Stretching: The Role of the Stretch Reflex. The muscle spindle is a long thin nerve receptor found within the muscle. Information from this receptor transmits information to the spinal cord regarding muscle length and the speed of lengthening.
