Which statement about PERT is correct?

• A. It can be used with galvanic and shortwave
• B. It cannot be used with galvanic currents
• C. It is only compatible with laser therapy
• D. It has no relation to current types

Answer: (A)

PERT is a technique in electrolysis that uses both galvanic and shortwave currents. This combination brings together the chemical action produced by galvanic current with the tissue-heating effect of shortwave energy, allowing both mechanisms to work together to destroy the hair follicle more efficiently. Because of this dual-action nature, PERT can be used with galvanic currents and with shortwave currents, rather than being limited to one type or to laser therapy alone. The other statements ignore this dual-current approach or wrongly assign PERT to a single modality, which isn’t accurate.
