faradics

Question 1

what are faradic and sinusoidal currents

Answer 1

are low nerve muscle rent group with tolerance frequencies of 40 to 80 Hz

Question 2

what type of current is faradic

Answer 2

asymmetric bipolar alternating current

Question 3

surged current

Answer 3

gradual increase and decrease of peak intensity

Question 4

asymmetric bipolar alternating current

Answer 4

1. induced asymmetrical alternating current
2. biphasic, asymmetrical unbalanced spiked
3. positive portion-short duration high intensity and spike [second phase]
4. negative portion= long duration, less intensity and curved [1st phase]

Question 5

physiological effects on sensory neurons

Answer 5

slightly prickling sensation
mild erythema

Question 6

physiological effects on motor neurons

Answer 6

contraction
metabolism increases
vasodilation

Question 7

other effects of faradic

Answer 7

has n heating effect
no chemicals
increases circulation
denervated muscle insufficient transit time

Question 8

what are sinusoidal currents

Answer 8

low frequency currents that alternate equally
f=50-100Hz
duration=10ms

Question 9

different of sinusoidal from faradic

Answer 9

1.has more marked stimulation=improve circulation both locally and general
2.more painful, because the time of stimulation is longer

Question 10

factors causing degeneration reaction

Answer 10

1.nerve or nerve root complete cut
2. any pressure on the nerve
3. excessive stretching of the nerves
4. toxic neuropathies
5. conditions arise from anterior horn destruction of medulla spinalis

Question 11

nerve lesions causing paralysis

Answer 11

Neuropraxia
Axonotmesis
Neurotmesis

Question 12

neuropraxia

Answer 12

temporary damage that does not break axonal integrity
mildest peripheral nerve damage

Question 13

axonotmesis

Answer 13

a damage but not in C.T but causes disruption of the axons in the nerve cells
Wallerian degeneration on distal side
3 to 4 days after injury

Question 14

Wallerian degeneration

Answer 14

active process of retrograde degeneration of distal end of axon that is a result of nerve lesion
between 7 to 21 days

Question 15

neurotmesis

Answer 15

completely disrupts neural integrity by damaging both axons and connective tissue.
wlallerin degeneration ocuurs on proximal side

Question 16

clinical uses of faradic

Answer 16

1. treatments of weak and atrophied muscles
2. muscle reeducation
3. train new muscle fnx
4. treat paralyzed muscle
5. increase circulation
6. solving + preventing adhesion
   7.reducing pain
7. electrodiagnosis
8. constipation

Question 17

preferable application technique

Answer 17

motor point stimulation

Question 18

application techniques

Answer 18

1. motor point stimulation
2. group stimulation
3. in water application
   4.faradism under pressure to relieve edema

Question 19

contraindications of faradic

Answer 19

unreliable patients
loss of sensation
cancer
tb
acute inflammation
skin lesion
thrombosis
