PT Science: Synergies, Stages of Motor Recovery & Atypical Mov't

Question 1

What is a synergy?

Answer 1

coordinated movements that occur when multiple muscle groups are activated simultaneously

Question 2

True or False: The flexion synergy dominates in the leg and the extension synergy dominates in the arm

Answer 2

False: the flexion synergy dominates in the arm and the extension synergy dominates in the leg

Question 3

Jen has a CMSA score of 5 in her arm, what does this score indicate?

Answer 3

score 5: Relative independence from basic synergy. Synergy patterns can be reversed even if the movement occurs in the stronger synergy first.

Question 4

Marc has a CMSA score of 3 in his R leg, what does this indicate?

Answer 4

Score 3: Synergistic movements (or components) can be elicited voluntarily.

Question 5

What are the stronger synergies that occur in the upper extremity?

Answer 5

Flexor synergies**
- elbow flexion

Extensor synergy
- shoulder adduction & internal rotation

Question 6

Why are shoulder abduction, ext rotation and elbow extension synergies weak?

Answer 6

because of how strong the elbow flexor, shoulder adduction & int rotation synergies are

Question 7

what are the stronger synergies that occur in the LE?

Answer 7

Extensor synergies**
- knee extension

Flexor synergies
- hip flexion

Question 8

Which stage should you start at for the leg, arm, hand & foot?

Answer 8

Stage 4 for leg
Stage 3 for arm, hand, & foot

Question 9

How can the pt progress to the next stage?

Answer 9

being able to perform 2/3 tasks - if this is not achievable, test at lower stage

Question 10

how many attempts does the pt receive for each task?

Answer 10

2

Question 11

True or False: stages of motor recovery are passed through consecutively and progress may start and stop at any stage

Answer 11

True

Question 12

Name the Stages of Motor Recovery

Answer 12

1. Flaccid paralysis is present
2. No voluntary movement but movement can be facilitated or occurs as an associated reaction. (Please note: may also have minimal voluntary movement in stage 2).
3. Synergistic movements (or components) can be elicited voluntarily.
4. Simple movements are possible outside of synergy. Synergy patterns can be reversed if movement occurs in the weaker synergy first.
5. Relative independence from basic synergy. Synergy patterns can be reversed even if the movement occurs in the stronger synergy first.
6. Coordination and movement are near normal.
7. Normal
