Which condition requires caution when using electrotherapy?

• A. Regular exercise
• B. Balanced diet
• C. Pregnancy
• D. Good sleep

Answer: (C)

Safety considerations in electrotherapy focus on conditions that could be affected by electrical currents. Pregnancy requires caution because applying electrical stimulation to the abdomen or pelvic area could influence uterine activity or fetal safety, and many guidelines prefer avoiding stimulation in these regions during pregnancy unless there is clear medical justification and appropriate supervision. The other options—regular exercise, balanced diet, and good sleep—do not in themselves create safety concerns specific to using electrotherapy. They are general health factors and do not establish a contraindication to the therapy.
