medium frequency currents Flashcards
describe medium wave currents
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
types of medium frequency currents
yasnoporodskii
nemec
Yasnoporodskiil is ?
sinusoidally modulated currents(by LFC).
Constant 5000hz
Carrier for deeper penetration
nemec is?
Interferential currents
what onstant frequency must carriers posess
5000hz.
how is the sinusoidal shape of MFC acheived
by modulation MFC with LFC
Frequency of the LFC for modulation can be 10-20/ 30-150 hz
define depth of modulation
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.
how is the analgesic effect of yasnoporodskii reached
Higher frequency
DOM= low depth of 0-25%
? does this mean less LFC? Should do
how is the irritative effect of yasnoporodskii reached
Low freq
DOM= high depth of 75-100%
list the four types of sinusoidally modulated currents
- 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
modulated current For pain relief:
continous current Chosen LFC frequency and DOM
modulated current
For healthy muscles
Sinusoidal currents with alternating pauses betw/
modulated current For acute pain syndromes and adnexitis
series of sinusoudal currents with areas of non modulated MFC currents
modulated current Strongest analgesic effect for acute pain
a Series of sinusoidal currents alternated w/ fixed LFC freq of 150hz
another name for interferencial currents
nemec
