VAS Pain Scale — Visual Analog Scale

Calculates pain intensity using the Visual Analog Scale (VAS), a 100mm line anchored at "no pain" (0 mm) and "worst imaginable pain" (100 mm). Mild pain: 0–30 mm; moderate: 31–70 mm; severe: 71–100 mm. VAS is used in clinical trials and chronic pain monitoring.

Clinical Guidance

BMI is a screening measure of body size, not a direct measure of body fat. The standard WHO categories are underweight (<18.5), normal (18.5–24.9), overweight (25–29.9), and obese (≥30).

BMI can overestimate body fat in athletes with high muscle mass and underestimate it in older adults with low muscle mass. Interpret it alongside waist circumference and clinical context rather than as a standalone diagnosis.

How It Works

Calculates pain intensity using the Visual Analog Scale (VAS), a 100mm line anchored at "no pain" (0 mm) and "worst imaginable pain" (100 mm). Mild pain: 0–30 mm; moderate: 31–70 mm; severe: 71–100 mm. VAS is used in clinical trials and chronic pain monitoring

Each component has a specific meaning:

  • Visual Analog Scale — The visual analog scale recorded for the scenario being assessed.
  • 100mm line anchored at "no pain" — The 100mm line anchored at "no pain" recorded for the scenario being assessed.
  • "worst imaginable pain" — The "worst imaginable pain" recorded for the scenario being assessed.

Note: Interpret the vas pain result against the thresholds and context described above.

How to Use

Enter the Visual Analog Scale, 100mm line anchored at "no pain", "worst imaginable pain" for the scenario you are assessing. Calculates pain intensity using the Visual Analog Scale (VAS), a 100mm line anchored at "no pain" (0 mm) and "worst imaginable pain" (100 mm). Mild pain: 0–30 mm; moderate: 31–70 mm; severe: 71–100 mm. VAS is used in clinical trials and chronic pain monitoring. Use the vas pain result to inform your calculation.
