1
New cards

How do you test strength

manual muscle testing and dynamometry

2
New cards

how do you test ROM

goniometry and muscle length tests

3
New cards

what is AROM

patient moves their limb using their own muscles

4
New cards

what is AAROM

patient has help to move their limbWh

5
New cards

what is PROM

patient does not participate AT ALL in moving their limb

6
New cards

what is RROM

patient performs AROM with resistance

7
New cards

Patient lifts leg into hip flexion (AROM, AAROM, PROM, RROM?)

AROM

8
New cards

The patient uses a dowel to perform shoulder flexion with both arms (AROM, AAROM, PROM, RROM?)

AAROM

9
New cards

The therapist moves the patient’s knee into flexion (AROM, AAROM, PROM, RROM?)

PROM

10
New cards

what is an end feel?

sensation transmitted to the therapist’s hand at the extreme end of the PROM that indicates the structures that limit the joint movement

11
New cards

what are the 5 types of end feels?

hard, firm, soft, boggy, emtpy

12
New cards

is a hard end feel normal or abnormal?

both

13
New cards

is a firm end feel normal or abnormal?

both

14
New cards

is a soft end feel normal or abnormal?

both

15
New cards

is a boggy end feel normal or abnormal?

abnormal

16
New cards

is a empty end feel normal or abnormal?

abnormal

17
New cards

resistance applied by PT, graded on scale of 0/5 - 5/5

manual muscle testing

18
New cards

device used to resist a patient’s motion, numerical value attained (ft-lbs or N)

dynamometry

19
New cards

device used to measure joint angles

goniometer

20
New cards

grading of muscle strength is based on 3 factors, what are the 3 factors?

evidence of contraction, gravity as resistance, amount of manual resistance applied

21
New cards

what is the make test?

resistance must not “break” the muscle contraction so that the patient cannot hold the posistion

22
New cards

what is the break test?

resistance gradually decreases the resistance as the limb segment is felt to fall towards the muscle’s outer range

23
New cards

What is a grade 5 MMT?

full available ROM against gravity and against maximal resistance

24
New cards

What is a grade 4 MMT?

full available ROM against gravity and against moderate resistance

25
New cards

What is a grade 4- MMT?

greater than one half the available ROM against gravity and against moderate resistance

26
New cards

What is a grade 3+ MMT?

(through range) less than one half the available ROM against gravity and against moderate resistance

(isometrically) the full available ROM against gravity and against minimal resistance

27
New cards

What is a grade 3 MMT?

the full available ROM against gravity

28
New cards

What is a grade 3- MMT?

greater than one half the available ROM against gravity

29
New cards

What is a grade 2+ MMT?

less than one half the available ROM against gravity

30
New cards

What is a grade 2 MMT?

the full available ROM gravity eliminated

31
New cards

What is a grade 2- MMT?

less than the full available ROM gravity eliminated

32
New cards

What is a grade 1 MMT?

none of the available ROM gravity eliminated and there is a palpable or observable flicker of a muscle contraction

33
New cards

What is a grade 0 MMT?

none of the available ROM gravity eliminated and there is no palpable or observable muscle contraction

34
New cards

When applying resistance, best practice is to…

never cross another joint
