Occupational Therapist Test Biomechanics and Kinesiology 1

Question 1

Which plane of motion divides the body into anterior and posterior halves?

Accepted Answer

Frontal (coronal) plane

Answer

The frontal (coronal) plane divides the body into anterior and posterior halves; abduction and adduction movements occur in this plane.

Question 2

Which type of joint allows the greatest range of motion across multiple planes of movement?

Accepted Answer

Ball-and-socket joint

Answer

Ball-and-socket joints, such as the hip and glenohumeral joint, permit multiplanar movement including flexion, extension, abduction, adduction, and rotation.

Question 3

Which type of muscle contraction occurs when the muscle generates force while simultaneously lengthening?

Accepted Answer

Eccentric contraction

Answer

Eccentric contraction involves muscle force production while the muscle lengthens, as seen when lowering a weight under control.

Question 4

The 'power grip' in hand function is best described as:

Accepted Answer

Palmar prehension using all digits and the palm to hold an object

Answer

Power grip involves wrapping the fingers and palm around an object with the thumb providing counter-pressure, maximizing grip force for cylindrical or spherical objects.

Question 5

Normal shoulder flexion range of motion in a healthy adult is approximately:

Accepted Answer

180 degrees

Answer

Normal shoulder flexion is 0–180 degrees, representing the full arc from anatomical position to full overhead elevation.
