PNF principles

Question 1

After discharge

Answer 1

Any somatosensory stimulation has a continuation of the stimulus after the cessation of the stimulus

Question 2

Temporal summation

Answer 2

Repeated stimuli occurring within a short amount of time combine to cause excitations

Question 3

Spatial summation

Answer 3

Weak stimuli applied to different areas of the body simultaneously reinforces the facilitatory effect to cause excitation

Question 4

Irradiation

Answer 4

Overflow from stronger muscle groups to weaker muscle groups increases the strength of the response

Question 5

Successive induction

Answer 5

Contraction of an agonist muscle causes reciprocal inhibition of the antagonist. Once the agonist relaxes, the inhibition ceases and there is increased excitation of the antagonist (now the agonist).

Question 6

Reciprocal innervation

Answer 6

Contraction of muscles leads to simultaneous relaxation of their antagonists

Question 7

Autogenic inhibition

Answer 7

By isometrically contracting a muscle, a reflex reaction occurs in the same muscle that the Golgi tendon organ is stimulated and the resistance to stretch is lowered, therefore increasing ROM
