Proprioceptive Neuromuscular Facilitation
(PNF) is an advanced form of flexibility training
that involves both the stretching and contraction of the muscle
group being targeted. PNF stretching was originally developed
as a form of rehabilitation, and to that effect it is very
effective. It is also excellent for targeting specific muscle
groups, as well as increasing flexibility and range of movement.
It also improves muscular strength.
Contract –Relax PNF:
It involves the therapist asking the patient to fire the tight
muscle isometrically against the therapist's hand for roughly
6 to 10 seconds. Then, the patient relaxes and the therapist
lengthens the tight muscle and applies a stretch at the newly
found end range. This technique utilizes the golgi-tendon
organ, which relaxes a muscle after a sustained contraction
has been applied to it for longer than 6 seconds.
