IMPORTANT TERMS

Flexibility

Stretching

PNF

flexibility
FLEXIBILITY

Ability to move a single joint or a series of joints through a complete, unrestricted and pain-free ROM

Essential to prevent injuries and maintain function

stretching
STRETCHING

Any therapeutic maneuver to lengthen shortened soft tissues

Agonist: Muscle opposite to the tight muscle

Antagonist: Tight muscle

mechanism
MECHANISM

Sustained stretch => sarcomeres added in series

Quick stretch => stretch reflex

pnf stretching1
PNF STRETCHING

Help in relaxing only the muscles and not other connective tissue…ligaments, capsules etc.

Only possible if the muscle to be stretched is normally innervated and under voluntary control

Sarcomere give will occur more easily when the muscle is relaxed

techniques
TECHNIQUES

Antagonist

Contract Relax

Hold Relax

Agonist

Agonist Contraction

Hold Relax with Agonist Contraction

procedure
PROCEDURE

Contract Relax

Take limb passively or resist movement of the limb to the limit of ROM

Change grip to resist active movement of tight muscle

Active contraction of tight muscle in a short range

Patient relaxes and limb taken further into the limited range

slide9
2. Hold Relax

Take the limb to the limit of ROM

Change grip to resist tight muscle

Resisted isometric contraction of tight muscle

Patient relaxes and limb taken further into the range

slide10
3. Agonist Contraction

Take the limb to end range

Resisted isometric contraction of muscle opposite to the tight muscle

Patient relaxes and limb taken further into the range

slide11
4. Hold Relax with Agonist Contraction

Also called Slow Reversal Hold Relax

Prestretch isometric contraction of tight muscle and its relaxation

Followed by concentric contraction of the opposite muscle

Uses both reciprocal and autogenic inhibition

mechanism of pnf stretching
MECHANISM OF PNF STRETCHING

Stretching of muscle => muscle spindle stretched => Reflex contraction of muscle

Longer stretch => GTO stimulated => relaxation of muscle

Autogenic Inhibition: Prestretch contraction => relaxation by stimulation of GTO

Reciprocal Inhibition: Contraction of agonist => relaxation of antagonist
