Which element is part of a dosimetric plan regarding treatment session duration?

• A. Electrode placement
• B. Treatment duration
• C. Expected outcomes
• D. Modality choice

Answer: (B)

In electrotherapy, the amount of energy delivered to the tissues is set by how long the current is applied. A dosimetric plan for a treatment session specifies the duration because the total dose depends on both the current and the time of exposure. Specifying session duration ensures consistent, reproducible dosing and helps balance therapeutic effects with safety and comfort; longer durations deliver more energy and can enhance effects but also increase risk of skin irritation or discomfort, so the plan defines a precise length of time for the current to flow. Electrode placement targets the treatment area but doesn’t determine how long the current should be applied, modality choice describes the type of stimulation being used rather than the exact exposure duration, and expected outcomes describe goals rather than the dosing parameters.
