Question 1

Why do we measure ROM?

Answer 1

Passive Motion
Active Motion
Active Assistive
Muscle length
Show Progress
Provide rationale to DC or continue treatment

Question 2

What does passive ROM tell you about

Answer 2

Provides information about integrity of the joint surfaces and the extensibility of the joint capsule, ligaments, muscles, fascia and skin“Relax your arm as I move it through the available motion.”

Question 3

What does active ROM tell you about?

Answer 3

Provides information about muscle strength and possibly information about tissue extensibility“Lift your arm as high as you can. Only use the muscles in that area. Do not try to assist with your other arm.”

Question 4

Can adipose tissue affect end feel?

Answer 4

yes

Question 5

What is a muscle length test?

Answer 5

An assessment of the greatest extensibility of a muscle-tendon unit.

Question 6

For positioning the pt. for goniometric measurements, what should be considered?

Answer 6

For goniometric measurements, the patient should be in a position that reduces muscle tension of the antagonist.

Question 7

What is validity?

Answer 7

The degree to which an instrument measures what it claims to measure.

Question 8

What is reliability?

Answer 8

The amount of consistency between successive measurements of the same variable

Question 9

How do you improve reliability?

Answer 9

take multiple measurements or have same person measure
