Which is a contraindication to biofeedback?

• A. Skin irritation at electrode site
• B. Improved neuromuscular control
• C. Pain reduction
• D. Increased strength

Answer: (A)

Biofeedback depends on reliable skin–sensor contact to measure signals like muscle activity. When the skin at the electrode site is irritated or damaged, placing sensors can worsen the skin, cause discomfort or an allergic reaction to the electrode materials, and produce poor, unreliable readings. Because of these risks and the need for accurate data, skin irritation at the electrode site is a contraindication to proceed with biofeedback until the skin is repaired or a different setup is used. The other options describe potential therapeutic outcomes of biofeedback (better neuromuscular control, pain reduction, increased strength) and are not contraindications.
