IFC UPDATED SCRIPT 2026 PRACTICE
SOLUTIONS GRADED A+
● What is a 'beat' in the context of IFC? Answer: A group of polyphasic
pulses perceived as one pulse, created by the interference of two
currents.
● How is beat frequency calculated in IFC? Answer: It is the difference
between the frequencies of the two currents.
● What is a key characteristic of IFC current delivery? Answer: There is
no duty cycle; stimulation is delivered 100% of the time.
● What type of electrode setup is required for IFC? Answer: A
quadripolar electrode setup with four electrodes.
● What are some indications for using IFC? Answer: Acute pain, chronic
pain, muscle spasm, edema, urinary incontinence.
● What IFC parameters are used for acute pain? Answer: High
frequency stimulation, intensity at sensory/tingling, frequency of 100-
150 bps.
