quiz 3

Question 1

what is the opposite of adaptive shortening

Answer 1

stretch weakness or positional weakness resulting from muscles remaining in an elongated position

Question 2

how long to hold a muscle test?

what type of contraction is used in a mm test?

Answer 2

5 seconds

resisted isometric

Question 3

how many degrees of hip flexion is anticipated w a straight leg raise

Answer 3

80 degrees of hamstrings

Question 4

muscle grading chart:

normal = ?

Answer 4

100% patient can maintain position against applied position

Question 5

muscle grading chart:

good = ?

Answer 5

75%

pt can maintain position against gravity & against applied examiner resistance

Question 6

muscle grading chart:

fair = ?

Answer 6

50% movement against gravity but not against resistance

Question 7

muscle grading chart:

poor - ?

Answer 7

25%

mvment possible but not against gravity

Question 8

muscle grading chart:

trace = ?

Answer 8

5% evidence of slight contractility

Question 9

muscle grading chart:

zero = ?

Answer 9

0% no palpable or perceivable evidence of contractility

Question 10

what mm groups are being tested during the scratch test in the upper arm

Answer 10

GH internal rotators

pec major
teres major
anterior deltoid
subscapularis
lat dorsi

Question 11

what mm are being tested during scratch test in the lower arm

Answer 11

GH external rotators

infraspinatus
posterior deltoid
teres minor

Question 12

what is passive insufficiency

Answer 12

shortness of a two joint muscle

when not allowing normal elongation over both joints simultaneously

Question 13

what is active insufficiency

Answer 13

inability of a multi joint muscle to generate effective force when placed in a fully shortened position

Question 14

what mm’s attach to coracoid process

Answer 14

pec minor
coracobrachialis
short head biceps brachii

Question 15

what are some cheats you see during a hip flexor length test

Answer 15

posterior thigh is lifted off table
knee extends
leg abducts
leg externally or internally rotated

Question 16

what to be aware of when doing a mm test

Answer 16

does contraction cause pain
note intensity, quality and location

strength of contraction 0-5

any substitutions - if weakness in mm testing, client will have other mm take over

Question 17

Which muscle fibres are being tested /lengthened when the client is supine with the arm abducted to 135 degrees and elbow straight?

Answer 17

pec major lower fibres

Question 18

strong and pain free

Answer 18

indicates no lesion of contractile unit being tested or the nervous tissue supplying that contractile unit

Question 19

strong and painful

Answer 19

indicates local lesion of the muscle or tendon

ex) mm strain

amount of strength is limited by pain

Question 20

weak and painful

Answer 20

indicates severe lesion around joint

ex) partial tear of tendon

Question 21

weak and pain free

Answer 21

indicates a rupture of a mm (3rd degree strain) or its tendon or lesion of the peripheral nerve or nerve root supplying that muscle
