Which pain scales are commonly used in rehabilitation to quantify pain intensity?

• A. Both Visual Analog Scale and Numeric Pain Rating Scale
• B. Visual Analog Scale
• C. Numeric Pain Rating Scale
• D. McGill Pain Questionnaire

Answer: (A)

In rehabilitation, quantifying pain intensity uses scales that convert the subjective feeling of pain into numbers for tracking change and guiding treatment. The Visual Analog Scale provides a continuous, fine-grained measure on a 10-centimeter line, which the patient marks to represent their current pain level. The Numeric Pain Rating Scale asks the patient to rate their pain with a simple number, usually from 0 to 10, making it quick and easy to administer. Both are commonly used because they’re straightforward, reliable, and easy to chart over time. The McGill Pain Questionnaire, while valuable for capturing broader qualitative aspects of pain (such as sensory and affective dimensions), is more time-consuming and not primarily used to quantify intensity alone, which is why the combination of Visual Analog Scale and Numeric Pain Rating Scale is typically preferred for simple intensity quantification.
