[Psychological and physiological changes accompanying pulmonary rehabilitation in patients with chronic pulmonary emphysema].

In 14 patients with chronic pulmonary emphysema, the relations between changes in psychological status associated with pulmonary rehabilitation and exercise tolerance were studied with the Cornell Medical Index and the Yatabe-Guiford Personality Inventory. Although the scores on the latter did not change, the cardio-respiratory score on the Cornell Medical Index improved significantly (p < 0.05). The only index of exercise tolerance that improved significantly was the distance walked in 10 minutes (p < 0.05). The changes in the scores of "Lack of Objectivity" and "Rhathymia" correlated negatively with the change in the distance walked in 10 minutes (R = -0.80, p < 0.01; R = -0.81, p < 0.01). The change in psychological status that accompanied pulmonary rehabilitation has been related to the improvement in the distance walked in 10 minutes.
