(80 cards)
1
Q
What should you ask if someone presents with an injury?
A
“Has this ever happened before, how was it treated?”
2
Q
When does the evaluation of a musculoskeletal injury happen?
A
- The moment you first lay eyes on the patient
*observe them when they’re unaware
3

If a patient has full AROM is there a reason to do PROM
A
No
4

If there is restricted AROM is there a reason to test PROM
A
Yes
*is the motion due to pain or physical restriction
5

A
Compare bilaterally
6

10
Q
How to document ROM
A
- FROM/ROM intact
- Record if any movement or plane is limited
- Record degree of limitation
11
Q
What are the two types of ROM
A
AROM
*patient is moving limb
PROM
*provider is moving limb for patient
12
Q
What factors influence ROM
A
- Patients willingness to move
- Muscular strength
- Motor control
- Osteoligamentous stability (any torn ligaments)
- Available joint motion (contracture, bone spurs)
13
Q
How does instability occur
A
- Results from deficiency in a joint stabilizing structure
*joint can dislocate
*joint may move in an unnatural way
14
Q
What is laxity
A
looseness of a joint, but may not be serve enough to cause instability

A
0 = no muscular contraction detected
1 = barely detectable flicker or trace of contraction
2 = active movement of the body part with gravity eliminated
16
Q
What are grades 3-5 of strength
A
3 = active movement against gravity (cant move against pressure)
4 = active movement against gravity and some resistance
5 = “normal” active movement against full resistance without even dent fatigue
