Faradic And Sinusoidal

Question 1

Faradic currents varry btw

Answer 1

1-1000 hz per second

Question 2

Most comfortable tolerance for frequency in faradic is

Answer 2

40-80

Question 3

Physiological effects on the sensory neuron

Answer 3

Slight prickling sensation
Feeling is not painful
Mild erythema

Question 4

Physiological effect on motor neurons

Answer 4

Causes contractions
Increased metabolism
Vasodilation
Tetanic current

Question 5

Effects of faradic

Answer 5

Heat
Chemical
Circulation
Denervated muscle

Question 6

Sinusoidal current

Answer 6

Low frequency currents that alternate equally
Frequency is 50-100hz
Current duration is 10ms
More painful
More marked stimulation of sensory nerve endings in the skin

Question 7

Faradic effects on the sensory nerves and motor nerves

Answer 7

Sensory nerves
. Sense of needling
Erythema and reflex vasodilation occurs

Motor nerves
. They create tetanic contractions
They contract the muscle innervated

Question 8

Factors causing degeneration reaction

Answer 8

Nerve or nerve root completely cuts
Pressure on the nerve
Conditions caused by excessive stretching of the nerves
Toxic neuropathies
Conditions from anterior horn destruction of the medulla spinallis

Question 9

What are the Nerve lesions causing paralysis

Answer 9

Neuropraksia
Axonotmesis
Neurotmesis

Question 10

Neuropraxia or grade 1

Answer 10

Temporary damage that doesn’t break the anoxal integrity
It’s the mildest peripheral nerve damage
Sensory motor problems occur in the proximal part of the damaged area

Question 11

Axontomesis grade 2

Answer 11

Causes distruption of the axons in the nerve cell

Wallerian degeneration occurs distally to the injury

Question 12

Wallerian degeneration

Answer 12

Is an active process of retrograde degeneration Of the distal end of an axon that is a result of a nerve lesion
It occurs between 7-21 days after the lesion occurs

Question 13

In Wallerian degeneration after 21 days acute nerve degeneration will show where

Answer 13

On the electromyograph

Question 14

What nerve lesion completely distrups the neural intergity

Answer 14

Neurotmesis

Question 15

Clinical use of faradic current

Answer 15

Treatment of weak and atrophied muscles

Muscle reeducation

Train new muscle function

Treatment of paralyzed muscles

Increase blood circulation

Increase venous and lymphatic circulation

Solving and preventing adhesion

Reducing pain with opposite irritation effect

Question 16

Application for Faradic

Answer 16

Prepare and test the patient 
Place the electrodes 
Surge the current 
Set intensity 
Control the patient

Question 17

Application technique for faradic

Answer 17

1. Motor point stimulation..,

Preferred method
Used in isolated muscles
Time 20-30 min

Question 18

Technique for application

Answer 18

2.Group stimulation
Put on origio and insertion

3. In water application

Question 19

For faradism under pressure

Placement of electrode for lower limb goes where

Answer 19

Active electrodes are placed over the belly of the calf muscle

Passive electrodes are placed over the sole of the foot

Question 20

Placement of electrodes for upper limb

Answer 20

Active electrodes are placed over the flexor aspect or forearm at the proximal and distal of the muscle belly

The passive electrode is placed over the palm or cubital fossa

Question 21

A surge duration and a surge interval respectively

Answer 21

3 sec
9 sec

Treatment time is 15-30 min

Question 22

When is group stimulation used

Answer 22

If several muscles originate from the same place

One end of the plate electrodes is placed on the nerve and other is placed on the body of the muscle
