Lecture 4 LO

Question 1

Be able to describe how to use the goniometer

-What is a goniometer?

Answer 1

-A device used for angle measurement

Question 2

Be able to describe how to use the goniometer

-Placement?

Answer 2

• Place goniometer over the fulcrum of the joint, with the stationary arm over the “body” and the moveable arm over the moving part
  
  • Generally the body is the proximal portion of the joint
  • Joint’s fulcrum is the point at which the joint moves
  • Stationary arm follows the reference line and serves as your baseline or 0 degrees

Question 3

Be able to describe how to use the goniometer

Answer 3

• The patient or examiner moves the joint to its end ROM following with the moveable arm of the goniometer
• Zero starting position = Extended anatomic position when doing measurments
• Important that stationary portion doesn’t move and that goniometer is parallel with bone
• Look at goniometer prior to removing to ensure accurate reading

Question 4

Discuss the relationship between neuromusculoskeletal dysfunction and decreased ROM
-Causes of loss of AROM?

Answer 4

• Loss of AROM has many causes

- Diminshed ROM is abnormal

Question 5

Discuss the relationship between neuromusculoskeletal dysfunction and decreased ROM
-Causes of loss of PROM?

Answer 5

• Loss of PROM is most commonly associated with SD

- Diminshed ROM is abnormal

Question 6

Discuss the relationship between neuromusculoskeletal dysfunction and ROM
-Increased ROM?

Answer 6

Increased ROM is abnormal if it is compensating for an adjacent area that is hypomobile

Question 7

Describe and demonstrate the concept of “linkage” as it pertains to the examination for joint ROM

• Relationship of joint mechanics with surrounding structures?
  
  • Examples?

Answer 7

• By linking multiple structures together you will get an increased ROM
• Examples-Shoulder-spine
  - Spine-hip/pelvis

Question 8

Describe and demonstrate the concept of “linkage” as it pertains to the examination for joint ROM

• Relationship of joint mechanics with surrounding structures
  
  • Very important to?

Answer 8

• Very important to isolate the joint you wish to examine to get an accurate measurement and evaluation of a particular joint
• Normal vs result of compensation

Question 9

Know the degrees of expected normal ROM of major joints

Answer 9
