Question 1

The close-packed position of the facet joints of the spine is in which of the following spinal positions?&#10;A) Flexion&#10;B) Extension&#10;C) Lateral bend&#10;D) Elevation

Accepted Answer

The close-packed position of the facet joints of the spine is in extension. This position provides the most stability and is the position in which the joints are the most congruent, meaning they fit together most tightly.

Question 2

The type of arthrokinematic motion characterized by linear movement of a joint surface parallel to the plane of the adjoining joint surface is which of the following?&#10;A) Roll&#10;B) Spin&#10;C) Glide&#10;D) Shear

Accepted Answer

The arthrokinematic motion characterized by linear movement of a joint surface parallel to the plane of the adjoining joint surface is called Glide. Roll is the rotational movement of one joint surface over another, Spin is the rotational movement of a single joint surface on one bone, and Shear is a sliding motion where the joint surfaces move in opposite directions parallel to the plane of the adjoining joint surface.

Question 3

The type of end feel that is defined by a lack of normal mechanical limitation of joint ROM is&#10;A) capsular.&#10;B) soft.&#10;C) empty.&#10;D) bony.

Accepted Answer

An empty end feel is defined as a lack of normal mechanical limitation of joint ROM, indicating that there is no true endpoint to the movement. This can occur in a joint that has very little or no tissue surrounding it, such as the radiocarpal joint. Capsular end feels occur when the joint capsule and ligaments surrounding the joint become taut or tense at the end of the available range of motion. Soft end feels can occur when the joint is blocked by tissue, such as in a muscle spasm or swelling. Bony end feels occur when the bones of the joint come into contact with each other, indicating that the available range of motion has been reached.

Question 4

The type of arthrokinematic motion characterized by rotation of one surface on a fixed adjacent surface is called&#10;A) roll.&#10;B) spin.&#10;C) glide.&#10;D) Any of the above

Accepted Answer

The type of arthrokinematic motion characterized by rotation of one surface on a fixed adjacent surface is called spin. The other two options, roll and glide, involve linear movement along the surface. Therefore, the correct choice is B, spin.

Question 5

Hip abduction is an example of which type of motion?&#10;A) Arthrokinematic&#10;B) Osteokinematic&#10;C) Angular&#10;D) Torque

Accepted Answer

Hip abduction involves movement of the femur away from the midline of the body, which is an example of osteokinematic motion. Arthrokinematic motion involves movement between joint surfaces and torque involves a force that causes rotation. Angular motion involves movement along an angle or curve.

Question 6

According to the convex-concave law,the convex femoral head during hip flexion moves in which direction in relation to the direction the femur moves?&#10;A) Same direction&#10;B) Opposite direction&#10;C) First the same direction,then the opposite direction at the end of the movement&#10;D) It depends on whether the person is standing or lying down.

Accepted Answer

According to the convex-concave law, the convex femoral head during hip flexion moves in the opposite direction in relation to the direction the femur moves. This is because the convex surface of the femoral head slides in the concave acetabulum while it moves during hip flexion.

Question 7

The type of abnormal end feel characterized by the presence of soft tissue edema is which of the following?&#10;A) Boggy end feel&#10;B) Springy block&#10;C) Empty end feel&#10;D) Soft tissue approximation

Accepted Answer

A boggy end feel is characterized by excessive soft tissue edema or swelling that gives a spongy or mushy resistance to passive motion. This type of end feel is commonly seen in joint inflammation or acute injury.

Question 8

The type of joint end feel characterized by a leatherlike limitation with some give is&#10;A) bony.&#10;B) soft tissue approximation.&#10;C) capsular.&#10;D) empty.

Accepted Answer

The leatherlike limitation with some give end feel is characteristic of a capsular end feel, which occurs when the joint capsule has reached its limit of motion and provides resistance. Bony end feel is hard and abrupt, soft tissue approximation end feel is squishy, and empty end feel occurs when there is no resistance due to the joint being unstable or the examiner not reaching the end range of motion.

Question 9

Motions occurring within the joint that are necessary for joint motion but are not under voluntary control are called&#10;A) osteokinematic movement.&#10;B) accessory movement.&#10;C) springy block.&#10;D) manipulation.

Accepted Answer

Accessory movements are small, non-voluntary movements that occur within the joint that are necessary for normal joint motion. These movements are not under conscious control, and are necessary for normal joint function. Osteokinematic movements, on the other hand, are voluntary movements that can be consciously controlled. Springy block and manipulation are not terms commonly used to describe joint movements.
