interferential currents Flashcards
Interferential current it is based on the overlap of
2 0r 3 medium frequency sinusodial currents
the current intensities from the interferential currents are realized by the entry of what
two different sinusodial alternating currents
with the same frequencies
inteferential currents is characterized by what
generation of low frequency current pulses
the main parameter responsible for therapuetic and physiological effect is what
low frequency component of interferential current
what increases the excitability of deep and smooth muscles at 0-100
motor effect …. doesnt contract denervated muscles
has no thermal effect
less painful
which effect doesnt cause burn
sensory effect
phycological effects depends on what
magnitude of current
type of mode used
frequency range used
accuracy of elctrod epositioning
main clinical applications of physiological effects are
pain relief
muscle stimulation
increased local blood flow
reduction of edema
characteristics of plate electrodes
made of a conducting rubber which is comfortable and long lasting
larger electrodes are comfortable treatment and deeper effect
Smaller electrodes are for localized effects
vacuum interferential device
used for spasm in the in the neck and back regions and also painful regions
applied for 20-30 minutes
places where the electrodes can be placed
elbow knee neck shoulder lower back
the the transcutaneous application of
alternating mediumfrequency currents, amplitude
modulated at low frequency fortherapeutic purposes.is what
interferential currents
most of thr frequency currents are btw what hz
3900-4000
motor effects of interferential
its not painful
has no thermal effect
does not contract denervated muscle
increase the excitibility of deep and smooth muscles at frequencies btw 0-100
different hz , their efffect and thier indication
Fr. 0-10 Hz Contraction Muscle strentghing
Fr. 0-100 Hz Increase circulation Edema treatment
Fr. 90-100 Hz Sedative effect Pain relief
Fr. Sabit 100 Hz Analgesic effect Pain relief
