Which category corresponds to micro-current stimulation?

• A. Noxious stimulation
• B. Sub-sensory (micro-current)
• C. Sensory response
• D. Motor response

Answer: (B)

Micro-current therapy uses currents that are so small they fall below what a person can feel, placing it in the sub-sensory category. Because the patient does not detect any sensation, it isn’t described as a sensory response, a motor response, or a noxious (painful) stimulus. This is different from sensory stimulation, which is felt as tingling or warmth; motor stimulation, which causes muscle contraction; and noxious stimulation, which is painful. The sub-sensory nature of micro-current is why it’s categorized separately, often used to support healing processes without overt sensory effects.
