a-histamine
c- melanin
d- bradykinin
e- endorphin
The correct Answer is :
C- melanin is a responsible for a pigmentation .
61 -After exposure to U.V.R patient of come with Erthyrema due to
release
a-histamine
f- melanin
g- bradykinin
h- endorphin
The correct Answer is :
A- histamine is a responsible for Erthyema
62- Short wave (SWD) contraindications:
a- Phlebitis
b- Sprain
c- Muscle strain
d- Hematoma
The correct Answer is:
A- phlebitis as we described above.
63- for denervated ms we use at least
A-10 m.sec
B-50 m.sec
C-100 m.sec
D-300 m.sec
The correct Answer is:
C- 100 m.sec at least with denervated muscle , if he dosen`t say at least
we should choose 300 m.s or more
64-If there is tendonitis in this muscle the best method for treatment
a- US with deep friction massage
b- T N E S
c -SWD.
,The correct Answer is:
a-US with deep fiction massage as we described above.
65-Therapist use electrical method for pumping action with limb
elevated and compressed to
A-decrease edema
B-increase circulation
C-increase venous return
The correct Answer is:
A- Decrease edema, because we do pumping action with compressed
limb elevated
66-In bell`s palsy we use
a- continues direct frequency current
b- T.E.N.S
c- Interrupted direct current
C-interrupted direct current , because it`s innervated muscle.
67-patient coming with industrial burn involved the dorsum muscle of
the left hand after study there is dis-continues chronoxia227/m. so we
could use:
a- continues direct current
b- faradic current
c- interrupted direct current
The correct Answer is:
A- continues direct current , due to it`s appear in discontinues chronoxia
which mean that it`s denervated muscle
Rheobase: is the smallest current that will produce a muscle
contraction if the stimulus is of infinite duration; in practice an impulse
of 1ms (o. I sec) is used.
In denervation the Rheobase may be less than that of innervated
muscle, and it often rises as re-innervation commences. These changes
are not however sufficiently predictable to be reliable guides.
The Rheobase varies considerably in different muscles and according to
the skin resistance and temperature of the part, while a rise may be due
to fibrosis of the muscle.
, Chronaxie: The chronaxie is the duration of the shortest impulse that
will produce a response with a current of double the rheobase.
The chronaxie of innervated muscle is appreciably than that of
denervated muscle, the former being less and the latter more than 1ms
if the constant voltage stimulator is used. With the constant-current
stimulator the values are higher, but bear a similar relationship to each
other.
Chronaxie is not a satisfactory method of testing electrical reactions as
partial denervation is not clearly shown, the chronaxie being that of the
predominant state of the fibers; for example, the chronaxie of a muscle
with 25% of its fibers innervated would be the same as that of a
completely denervated muscle.

68-Applied electrical stimulation to area for long lasting period cause
a-skin irritation
b-weakness of ms
c-edema occure
The correct Answer is:
A- skin Irritation
69-Pt of bells palsy long time treated with (E.S) you
A- M.S weakness
B-no change
C-fibrosis in the affected side
The correct Answer is:
C-fibrosis in the affected side due to long use of electricity to stimulate
the muscles.
70-Aphysical therapist is performing electro -myographic testing. During
a maximal output test of the patient’s quadriceps muscle, 35% of the
motor unit potential is poly-phasic. What is the significance of this
finding?
A-It is normal in the quadriceps.
B-It is normal in the triceps brachii, not in the quadriceps
C-It is normal in the biceps brachii, not in the quadriceps
D-It is abnormal in any muscle.
