NPTE-PTA Therapeutic Exercise

Question 1

Which type of muscle contraction produces the greatest force?

Accepted Answer

Eccentric

Answer

Eccentric contractions produce the greatest force because cross-bridge cycling and passive elastic elements combine to resist lengthening.

Question 2

The SAID principle in rehabilitation stands for:

Accepted Answer

Specific Adaptation to Imposed Demands

Answer

The SAID principle states the body specifically adapts to the type of demands placed upon it during training.

Question 3

Which stretching technique uses alternating contraction and relaxation to increase ROM?

Accepted Answer

Contract-relax PNF stretching

Answer

Contract-relax PNF uses autogenic inhibition (contraction then relaxation of the target muscle) to allow greater ROM.

Question 4

Open kinetic chain (OKC) exercises for the knee are appropriate for:

Accepted Answer

Terminal knee extension strengthening of the quadriceps

Answer

OKC terminal knee extension isolates the quadriceps and is used for strengthening in specific ranges without graft stress.

Question 5

The overload principle states that for strength gains to occur:

Accepted Answer

The load must exceed what the tissue is accustomed to

Answer

The overload principle requires that the training stimulus exceed the body's current capacity to drive physiological adaptation.
