Background: Pulmonary rehabilitation (PR) is a complex intervention, which can improve health related quality of life. Responses to PR vary and tools to predict individual patient responses are not developed. This study assessed the impact of perceived exertion levels on COPD patient's outcome from PR Methods: A retrospective analysis of COPD patients who completed 12 sessions of a standardized PR programme with GOLD grade II/III COPD with COPD Assessment Test (CAT) >10. Patients recorded their subjective exercise intensity perception by using a Modified Borg Scale for Perceived Dyspnoea (RPD) during each exercise. Results: 55 COPD patients (45% male), mean age 68.6 ± 9.96, BMI 26.49 ± 5.79 kg/m2. We found a negative correlation between RPD above 2.25 and improvement in the CAT score (p=0.007, r= - 0.469). CAT improvement was insignificant below 2.25 RPD level. Results were sub-categorised: category 1 Borg < 2.25 (ΔCAT improvement 3.57), 2: 2.25 to 3.25 (Δ 9.5) and 3 above 3.25 (Δ 5.42). Highest CAT improvement was observed in the category 2. In contrast, RPD above 3.25 showed a lower range of improvement. Scatter plot shows improvement in the CAT values for RPD values above 2.25.
