Back 13

chair can act as stabilization

Front 14

Scapula elevation: position

Back 14

Pt: seated, arms resting at sides
OT: behind

Front 17

2 ways to evaluate muscle strength

Back 17

1. test of individual muscles
2. test strength of groups of muscles - used in MMT

Front 18

Muscle strength necessary to perform all ordinary ADL

Back 18

Good to normal

Front 19

Muscle strength that may be able to perform all ADLs but requires resting periods

Back 19

Fair plus

Front 20

Muscle grade that is able to move parts against gravity and perform light tasks that present little or no resistance

Back 20

Fair

Front 21

For every day of hospitalization, how many days are needed to recondition

Back 21

Front 22

With muscle strength below ____, ambulation is not possible

Back 22

F

Front 23

What is a patient with poor muscle strength able to do?

Back 23

perform some ADLs with mechanical assistance, and maintain ROM independently

Front 24

Patients with these muscle grades are completely dependent and can perform ADLs only with the aid of externally powered devices

Back 24

Trace and Zero

Front 25

MMT measures

Back 25

the maximum contraction of a muscle or muscle group

Front 26

3 criteria used to measure strength

Back 26

1. Evidence of muscle contraction
2. amount of ROM
3. amount of resistance against which the muscle can contract, including gravity as a form of resistance

Front 27

3 things MMT cannot measure

Back 27

1. Muscle endurance
2. Muscle coordination
3. Motor performance capabilities

Front 28

At the beginning of MMT what is the very first thing the examiner should do?

Back 28

Perform a visual check, assessing contour, symmetry and noting hypertrophy or atrophy

Front 29

Three things necessary for interrater reliability

Back 29

1. correct positioning
2. Careful stabilization
3. Correction palpation and observation

Front 30

Reproducability between examiners shows ___?

Back 30

test reliability

Front 31

5 Factors affecting the outcome of MMT

Back 31

1. Patient not interested
2. Positioning
3. Fatigue
4. Differences between therapists interpretation
5. Cognitive level of patient

Front 32

Break test

Back 32

patient asked to hold as tester provides external force to push or break them out of hold

Front 33

MMT sequence (6)

Back 33

1. Position
2. PROM
3. AROM/Palpate/Observations
4. Stabilize proximal to joint being moved
5. Provide resistance
6. Assign muscle grade
