1. Which of the following statements is TRUE?
a. Kinetics describes position, velocity, and acceleration of a moving object.
b. Biomechanics is the application of dynamics to the living body.
c. Arthrokinematics is the study of movements occurring between articular surfaces.
d. Kinesiology addresses force interaction during motion.
2. The radiocarpal joint of the wrist allows hand flexion/extension around a transverse
axis and abduction/adduction around a sagittal axis. The hand, therefore, can move
in two planes, and the joint is said to possess _____ degrees of freedom of
motion.[1-9]
a. 1
b. 2
c.3
d. 4
3. Which of the following movements does NOT move around a vertical axis when an
individual stands erect with the palm facing forward?
a. supination of the forearm
b. radial deviation of the wrist
c. abduction of the foot
d. rotation between the atlas (C1) and axis (C2)
4. As the hinged joint is compared with the pivot joint, which of the following statements
is TRUE?
a. Both of them provide one degree of freedom motion.
b. Both of them are biaxial joints.
c. Their distal ends are all concave and their proximal ends are all convex.
d. Their articular surfaces are covered with fibrocartilage.
5. Concerning with a convex on concave joint, which of the following statements is NOT
TRUE?
a. It indicates the articular surface of the proximal segment is convex where that of the
distal segment is concave.
b. The glenohumeral joint is one of the examples of the convex on concave joint.
c. The articular surface moves in the direction opposite to that of the moving bone.
d. It can provide both open and closed kinematic chain motions.

6. Which of the following statements about arthrokinematic movement is NOT TRUE ?
[1-24,26]
a. Arthrokinematic movement describes the movement occurring between two joint
surfaces.
b. Arthrokinemaic movement can be regarded as the path traced by movement of the
joint mechanical axis of the moving segment on the joint surface of the stationary
segment.
c. Arthrokinematic movement is classified as 4 categories: angular, circumduction,
rotation, and sliding.
d. Joint movement occurring in the absence of normal arthrokinematic movement may
cause impingement or dislocation.
7. When a person, holding on a high bar (高單槓) with the palms facing the face,
gradually pulls himself up, the motion occurs at the elbow is _____ and the muscle
works _____.
a. elbow flexion, concentrically
b. elbow extension, concentrically
c. elbow extension, eccentrically
d. elbow extension, eccentrically
8. Same motion as question 7, which of the following statements is NOT TRUE?
a. It is an open kinematic chain motion because the motion is against gravity.
b. It is an open kinematic chain motion because the distal segment of the motion chain
moves in space.
c. It is a closed kinematic chain motion because the motion is gravity-assisted.
d. It is a closed kinematic chain motion because the distal segment of the motion chain
is fixed while the proximal segment moves.
9. Follow question 7, then he lowers his body down, the motion occurs at the elbow is
_____ and the muscle works _____.
a. elbow flexion, concentrically
b. elbow extension, concentrically
c. elbow extension, eccentrically
d. elbow extension, eccentrically
10. Follow question 7, then he hangs still (吊在單槓上不動), the muscle involved works
as _____ contraction.
a. isotonic
c. isokinetic
b. isometric
d. isotopic
