Q

Based on principle II, the patient’s skin and subcutaneous fat act as…

A

a resistor to the therapeutic currents that we are trying to introduce to the underlying tissue

Q

Based on principle II, what should we keep in mind? (1.)

A

The amount of current that actually reaches the desired tissues is decreased

Q

Based on principle II, what should we keep in mind? (2.)

A

The patient may experience discomfort and/or skin irritation if the intensity of the current is increased in an attempt to move the current to deeper tissues

Q

What does principle III allow?

A

It allows more of the current to penetrate to deeper tissue with less intensity, affording a greater degree of patient comfort

Q

How many electrodes are required in IFC and how are they placed?

A

Four electrodes are placed in a quadripolar arrangement around the treatment site so that currents from the 2 channels cross at the treatment site at tissue level

Q

What is the concept of the crossed currents in IFC?

A

The two currents cross each other creating interference. When the two currents cross, they cancel themselves out leaving only the remaining difference in their frequencies, known as the beat (or resultant) frequency

Q

What is the use of quadripolar with sweep?

A

When a patient presents with a “general” painful site and cannot provide specifics, when electrode placement is less than optimal, and when the target treatment tissue spans over a large area

Q

What is the theory behind Wedensky inhibition?

A

Application of medium-frequency currents (IFC) creates a subsequent action potential failure. Therefore during this period of WI, no pain impulses can be transmitted

17
Q

What is the rate for gate theory?

A

80-150 bps

18
Q

What is the rate for endorphin theory?

A

1-10 bps

19
Q

What is the amplitude for gate theory?

A

Max sensory

20
Q

What is the amplitude for endorphin theory?

A

Mild motor

21
Q

What is the treatment duration for gate theory?

A

May range between 10-30 minutes

22
Q

What is the treatment duration for endorphin theory?

A

Should tend towards at least 20-30 minutes

23

A

acute conditions

24
Q

Thermotherapy and IFC is helpful for…

A

Chronic conditions
