IFC

is IFC effective for carpal tunnel syndrome?

grade C recommendation for short term pain relief in non surgical cases.

How is Interferential Current (IFC) produced?

It is produced by the interference of 2 medium to high frequency alternating currents where the frequencies are slightly different, resulting in a low frequency.

IFC can be used for ___ and ___ pain relief

acute and chronic

What are the primary clinical advantages of IFC compared to TENS?

IFC may be more comfortable and penetrates more deeply than TENS.

What is the main difference between IFC and Premodulated Current?

In Premodulated the frequency interference occurs within the machine, allowing the use of only one channel with two electrodes.

premodulated current is better for ____ areas compared to IFC

smaller

What is the purpose of the 'Sweep' parameter in IFC?

It automatically moves intensity and frequency between channels and leads to prevent nervous system accommodation.

What is the expected sensation for Conventional High Rate TENS or IFC?

A strong tingling or vibration sensation.

what is the electrode placement for IFC?

4 electrodes that X mark the spot (channels need to cross)

IFC and premodulated TENS

current: alternating

frequency: 80-100 pps

pulse duration: na

amplitude: tingling

duration: 5-10 min for acute, 20-30 for chronic pain

What documentation is required after applying electrotherapy?

Type of BPA, area treated, parameters, duration, outcomes (pre/post measures), complications, and pre-treatment assessments.
