Modified Borg Scale

A self-report rating scale used to measure the perceived intensity of physical sensations such as breathlessness, exertion, or pain, ranging from 0 (nothing at all) to 10 (maximal). Originally developed by Gunnar Borg in 1982, the Modified Borg Scale is widely used in pulmonary rehabilitation and exercise physiology to assess perceived dyspnea intensity and dyspnea-related distress and anxiety in people with chronic respiratory conditions. The scale allows patients to quantify subjective experiences, enabling clinicians and researchers to track changes in symptom perception over time and in response to different interventions or exercise conditions.
