NRS — Numeric Rating Scale for Pain

Assesses pain using the Numeric Rating Scale (NRS), an 11-point integer scale from 0 (no pain) to 10 (worst imaginable pain). Mild pain: 1–3; moderate: 4–6; severe: 7–10. NRS is the most widely used clinical pain scale due to ease of verbal and written administration.

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

Assesses pain using the Numeric Rating Scale (NRS), an 11-point integer scale from 0 (no pain) to 10 (worst imaginable pain). Mild pain: 1–3; moderate: 4–6; severe: 7–10. NRS is the most widely used clinical pain scale due to ease of verbal and written administration

Each component has a specific meaning:

  • Numeric Rating Scale — The numeric rating scale recorded for the scenario being assessed.
  • 11-point integer scale from 0 — The 11-point integer scale from 0 recorded for the scenario being assessed.

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