A) 2 to 3 degrees
B) 4 to 5 degrees
C) 6 to 7 degrees

Question 6

The passive movements and elevation of the body part are components of continuous passive motion that increase which factors?

B) Lymphatic and arteriole return
C) Venous and lymphatic return
D) Venous and arteriole return

Question 7

Throughout a range of motion,when is joint volume normally at its greatest?

A) Full extension
B) Full flexion
C) Midrange between flexion and extension
D) Volume does not change throughout a range of motion

Question 8

The application of continuous passive motion is thought to stimulate the circulation of synovial fluid,which enhances the uptake of nutrients by what tissue in the knee?

A) Meniscal cartilage and articular cartilage
B) Articular cartilage only
C) Meniscal cartilage only
D) Neither meniscal cartilage nor articular cartilage

Question 9

After surgery,continuous passive motion is typically used for ___hours a day.

A) 8 to 10
B) 2 to 4
C) 4 to 6
D) 6 to 8

Question 10

Which of the following are indications to treat with continuous passive motion? Select all that apply.

A) After joint arthroplasty
B) Joint contracture
C) Thrombophlebitis
D) After meniscectomy
E) Spastic paralysis

Question 11

Continuous passive motion can possibly provide pain reduction via the gate mechanism,which occurs from the stimulation of afferent nerves located in what tissues?

A) Muscle and joint
B) Skin and muscle
C) Joint and skin
D) Skin,joint,and muscle

Question 12

The pumping action created by continuous passive motion circulates synovial fluid and assists in the removal of what? Select all that apply.

A) Joint hemarthrosis
B) Periarticular edema
C) Blood from tissue surrounding the joint
D) Pitting edema
E) Lymphedema

Question 13

Which of the following is reduced during the realignment of collagen that occurs with the use of continuous passive motion? Select all that apply.

A) Functional shortening of collagen
B) Cross-linking of collagen
C) Capsular adhesions
D) Tensile strength of tendon
E) Tensile strength of allografts

Question 14

When compared to faster speeds,slower speeds of continuous passive motion are theorized to produce better tensile properties of healing tendons.

Question 15

Which form of continuous passive motion device allows for compensatory motion between the patient's extremity and the carriage of the device?

A) Free linkage design
B) Anatomic design
C) Nonanatomic design
D) Locked linkage design

Question 16

Which option below best represents the philosophy regarding the effects of continuous passive motion?

A) Motion that is never lost need never be regained.It is the regaining of movement that is painful.
B) Motion that is lost must be regained.It is the regaining of movement that is painful.
C) Motion that is lost must be regained.It is the loss of movement that is painful.
D) Motion that is never lost need never be regained.It is the loss of movement that is painful.

Question 17

What continuous passive motion design is most suitable for use with the knee?

A) Free linkage design
B) Anatomic design
C) Nonanatomic design
D) Locked linkage design

Question 18

While continuous passive motion can be used on many different joints,what joint is it predominantly used with?

A) Knee
B) Shoulder
C) Ankle
D) Elbow

Question 19

Continuous passive motion is more effective than static stretching when increasing range of motion due to soft tissue restriction.

Question 20

The decision to use continuous passive motion should be based on the specific pathology to be treated.
