medium frequency currents

Question 1

describe medium wave currents

Answer 1

Less skin resistance -> less irritation
Deeper penetration of tissues
Used as a carrier for lfc’s due to reduced side effects
Have the same effects as LFC but deeper

Question 2

types of medium frequency currents

Answer 2

yasnoporodskii

nemec

Question 3

Yasnoporodskiil is ?

Answer 3

sinusoidally modulated currents(by LFC).
Constant 5000hz
Carrier for deeper penetration

Question 4

nemec is?

Answer 4

Interferential currents

Question 5

what onstant frequency must carriers posess

Answer 5

5000hz.

Question 6

how is the sinusoidal shape of MFC acheived

Answer 6

by modulation MFC with LFC

Frequency of the LFC for modulation can be 10-20/ 30-150 hz

Question 7

define depth of modulation

Answer 7

how the MFC is affected by the LFC

More frequent LFC component is present, the more the MFC is modulated by it, the more irritation at the site.

Question 8

how is the analgesic effect of yasnoporodskii reached

Answer 8

Higher frequency
DOM= low depth of 0-25%
? does this mean less LFC? Should do

Question 9

how is the irritative effect of yasnoporodskii reached

Answer 9

Low freq

DOM= high depth of 75-100%

Question 10

list the four types of sinusoidally modulated currents

Answer 10

1. For pain relief: Chosen LFC frequency and DOM
   2.For healthy muscles:
   Sinusoidal currents with alternating pauses betw/
   3.For acute pain syndromes:
   Series of sinusoudal currents with areas of non modulated MFC currents
   4.Strongest analgesic effect for acute pain:
   Series of sinusoidal currents w/ fixed LFC freq of 150hz

Question 11

modulated current For pain relief:

Answer 11

continous current Chosen LFC frequency and DOM

Question 12

modulated current

For healthy muscles

Answer 12

Sinusoidal currents with alternating pauses betw/

Question 13

modulated current For acute pain syndromes and adnexitis

Answer 13

series of sinusoudal currents with areas of non modulated MFC currents

Question 14

modulated current Strongest analgesic effect for acute pain

Answer 14

a Series of sinusoidal currents alternated w/ fixed LFC freq of 150hz

Question 15

another name for interferencial currents

Answer 15

nemec

Question 16

describe nemec currents

Answer 16

Uses 2 electrical fields 2 electrodes per field
One field has a constant frequency of 4000hz
Another has an alternating frequency of 3900-4000hz and 4000-4100hz
Where the fields cross their interference causes a current possessing the frequency that’s the difference of the 2 fields

Question 17

Therapeutic freq of IC for Analgesia

Answer 17

Constant = 100hz

alternating=90-100hz

Question 18

Therapeutic freq of IC for Trophic

Answer 18

constant=50-100hz

alternating=0-100hz

Question 19

Therapeutic freq of IC for Healthy muscle stim

Answer 19

constant=0-10hz

alternating

Question 20

Therapeutic freq of IC for Bone stim

Answer 20

Constant
alternating =90-100hz
Low frequency pulse magnetic field

Question 21

which two electrical methods cause bone stim

Answer 21

low frequency pulse currents

Interferential currents
