IFC Flashcards
What is IFC used for?
- Muscle strengthening (kinda)
- Pain control
- Circulation promotion
- Edema control
________ _____ is amplitude modulated, biphasic, symmetrical, balanced, has a pulse duration of ~___ micro sec and a phase duration of ~___ micro sec
interferential current; 250; 125
What effects in tissues would you expect from IFC ?
- Electrophysical
2. Cell signalling
IFC has a therapeutic effect in pain management due to endogenous opiate release in a _______ pathway
descending
IFC has therapeutic effects due to depolarization of ________ nerves.
peripheral
Capacitance reactance is ________ dependent.
frequency
The reduction in impedance is due to the higher frequency, NOT the shorter pulse duration (T/F).
FALSE; due to shorter pulse duration
What are 2 reasons to use medium frequency current in IFC?
- Comfort
2. Depth
By using 2 separate currents and crossing them at depth in the tissues, it is possible to deliver more _______ to the deep tissue.
voltage
Is the pattern of stimulation in IFC focused centrally, like in a 4-leaf clover?
NO
The pattern of stimulation in IFC is diffuse due to ______ ____ between adjacent electrodes.
current flow
Current does not spread outside of the borders of the 4 electrodes (T/F).
FALSE - it does
What should you know about quadripolar plate electrodes?
That the small electrodes can cause burns due to current intensity
What should you know about quadripolar probe electrodes?
TO NOT USE THEM!
There (is/is not) evidence to support the use of vector sweep.
is NOT
