Q

What is the problem with using MMT in pts with CNS lesions?

A

MMT tests ability of individual muscles to actively produce force. Pts with CNS lesions may not be able to produce isolated movements, may still have primitive reflexes

Q

How is active movement initiated?

A

Voluntary movement to command
Spontaneous movement
Reflexive movement

Q

What is plasticity?

A

“Natural recovery” refering to recovery that occurs as a result of physillogical healing properties in the body.

Q

When are limb synergies highly predictable?

A

Only after Cortical CVA’s. Also very characteristic of the stage of recovery

17
Q

What is the Flexion synergy seen in the UE after cortical CVA?

A 
Scapula
-retraction, elevation
Shoulder
-abduction, ER
Elbow
-Flexion
Forearm
-supination
Wrist/finger
-Flexion
18
Q

What is the extension synergy seen in the UE after cortical CVA?

A 
Scapula
-protraction
Shoulder
-horizontal adduction, IR
Elbow
-extension
Forearm
-pronation
Wrist/finger
-Flexion
19
Q

What is the Flexion synergy seen in the LE after cortical CVA?

A 
Hip
-flexion, abduction, ER
Knee
-Flexion
Ankle
-DF, inversion
Toes
-Flexion
20
Q

What is the extension synergy seen in the LE after cortical CVA?

A 
Hip
-extension, adduction, IR
Knee
-Extension
Ankle
-PF, inversion
Toes
-Extension
21
Q

How do you grade Motor control?

A

Pt performs movement without facilitation by therapist/ Estimate the AROM that can be performed (% or fraction) at each joint without any synergistic movements

22
Q

What do you make sure you include when documenting motor control?

A

The % or AROM as well as description: which joint, which direction and the testing position

23
Q

What do you need to consider when grading/documenting trunk/head motor control?

A

Can the pt isolate trunk and head from limbs?

Can they isolate pelvic movements from limb and trunk?

24
Q

What is a good way at assessing motor control?

A

Functional tasks IE: HIp extension in supine-pt can bridge 1/2 range 5 times but B knees move into extension

25
Q

Fugl-Meyer

A

see ppt

26
Q

Stage 1 of the Brunnstrom Stages of Motor Recovery

A

flacidity, no movement present (reflex or voluntary

27
Q

Stage 2 of the Brunnstrom Stages of Motor Recovery

A

Weak associated reactions appear or minimal voluntary movement responses are present in limb synergies. Spasticity begins to develop

28
Q

Stage 3 of the Brunnstrom Stages of Motor Recovery

A

All movements are in synergy although synergies may not be through full ROM. Spasticity peaks

29
Q

Stage 4 of the Brunnstrom Stages of Motor Recovery

A

Some movement combinations out of synergy are possible and mastered with difficulty. Spasticity is decreasing

30
Q

Stage 5 of the Brunnstrom Stages of Motor Recovery

A

Synergies lose their dominance; more difficult movement combinations can be mastered. Spasticity further decreases

31
Q

Stage 6 of the Brunnstrom Stages of Motor Recovery

A

No synergies; full isolated joint movements are possible but decreased coordination present. Spasticity present only during active rapid movements.

32
Q

Stage 7 of the Brunnstrom Stages of Motor Recovery

A

Normal movements performed; normal muscle tone
