During the vibration perception test, what should the patient report?

• A. When they feel the vibration start and end
• B. The intensity of vibration
• C. The color of light
• D. The temperature change

Answer: (A)

During a vibration perception test, the patient should report when the vibration begins and when it ends. This lets you measure not only the presence of vibration but also how long the sensation lasts, which reflects the functioning of the large myelinated fibers and related sensory pathways. If the patient only notes that they feel it, you miss information about the exact onset and offset, making it harder to determine the vibratory perception threshold. The other options—reporting the intensity, the color of light, or a temperature change—don’t pertain to what this test assesses.
