The duration of the program was 2-hours per/week (1-hour exercise and 1-hour education). Pre and post-rehabilitation outcome measures were evaluated using the DASS-21 scale, the incremental shuttle walk test (ISWT), the St-Georges Respiratory Questionnaire (SGRQ) and the Medical Research Council scale (MRC). Anxiety was measured by the Anxiety Inventory for Respiratory disease scale (AIR).Results The mean (SD) age was 71(8.4) years. The DASS-21 scale was responsive to PR with a mean change pre versus post scores for depression [8.67 vs.7.01 t= 3.26 p< 0.001], for anxiety [8.55 vs. 7.01, t = 2.81 p<0.005], for stress [9.88 vs.7.69, t = 3.99 p<0.001] following PR. Table 1 shows change in DASS-21 items in relation to clinically relevant variables following PR.

Further studies are needed in long-term follow-up. ER -
