Questions 2

Question 1

How is passive insufficiency different from joint ROM?

Answer 1

Passive insufficiency has to do with muscle length whereas joint ROM has to do with joint structures (ligaments, articular cartilage, joint shape).

Question 2

If a muscle that crosses 2 or more joints cannot passively elongate enough to all full simultaneous motion in all joints that if crosses, that is called?

Answer 2

Passive insufficiency

Question 3

Horizontal plane is?

Answer 3

vertical axis

Question 4

Sagittal plane is?

Answer 4

Medial-lateral axis

Question 5

Frontal plane is?

Answer 5

Anterior-posterior axis

Question 6

What does a minus sign before the first number mean when recording ROM measurements?

Answer 6

The client cannot get to anatomic position (fully extend or abduct)

Question 7

What is the sum of flexion active range of motion at the metacarophalangeal, proximal interphalangeal and distal interphalangeal joints, minus any active extension lack (short of zero) at these three joints?

Answer 7

Total active motion

Question 8

The finger metacarpophalangeal joint is measured in one movement, from hyper-extension to flexion. According to recording ROM, index finger metacarpophalangeal AROM of +25/25 indicates what?

Answer 8

Hyperextension and lack of full flexion

Question 9

A plane joint is an example of?

Answer 9

diathrosis

Question 10

What are mandatory characteristics of a synovial joint?

Answer 10

• Sensory nerves in joint capsule
• Joint cavity filled with synovial fluid
• Blood vessels in the joint capsule
• Capsular ligaments
• Articular cartilage covering the ends of the bones

Question 11

You ask a client who is seated in front of you with their arm at their side to flex their elbow against gravity. Form a fully extended position, they can only flex it 30 degrees or so. You know that the patient has full PROM at that elbow. In order to determine their muscle strength grade, your next step would be to?

Answer 11

Put the patients arm in a gravity-minimized position and ask them to flex their elbow in that position.

Question 12

T/F - Manual muscle testing has poor validity but good inter-rater reliability?

Answer 12

False

Question 13

Which of the following joints typically has 1 degree of freedom?

Answer 13

Pivot joint

Question 14

You ask your patient to extend their wrist, and they demonstrate full AROM against gravity; furthermore, they are able to take slight resistance before “breaking”. What is the muscle grade?

Answer 14

3+/5

Question 15

A firm end feel indicates what?

Answer 15

Connective tissue around the joint tightening

Question 16

• Heteropic ossification
• Unhealed fracture in a bone adjacent to the joint

Are examples of?

Answer 16

Contraindications to measuring ROM

Question 17

According to the biomechanical frame of reference. What is the first deficit that is addressed?

Answer 17

Structural stability

Question 18

The interphalangeal joints of the fingers are?

Answer 18

hinge joint

Question 19

T/F - A hard end feel is always pathologic?

Answer 19

False

Question 20

Which of the following is not a precaution for manual muscle testing?

Answer 20

Osteoporosis

Question 21

You ask your patient who is seated in front of you to flex their shoulder. They are able to complete this motion through a full ROM, but cannot take any additional resistance. Their muscle grade is?

Answer 21

3/5
