PNF1

When one muscle groups activity overflows to another muscle group, this is called:

• synergism

• irradiation

• approximation

• dissociation

Answer explanation

Irradiation-one body part’s activity produces overflow into another, more intensity causes more overflow

Trunk flexor overflows into dorsiflexors and hip flexors

trunk extension produces overflow into the hip and knee extensors.

upper extremity extension and adduction produces overflow into the trunk flexors.

hip flexion, adduction, and external rotation produces overflow into the dorsiflexors

Strong muscles can essentially assist weaker ones

 

Which of the following techniques causes co-contraction?

• approximation

• irradiation

• traction

• quick ice
