Abstract

Introduction:Cognitive impairment has been well described in patients with Chronic Obstructive Pulmonary Disease (COPD) in addition to cardiorespiratory disability. To reduce this impairment, researchers have recommended the use of single or combined exercise training. However, the combined effect of cognitive training (CT) and pulmonary rehabilitation (PR) program on selective cognitive abilities in patients with COPD has not been evaluated yet.The main aim of the study was to evaluate the impact of PR combined with CT on cardiorespiratory and cognitive parameters in patients with COPD.

Methods:Thirty-nine patients with COPD were assigned to an intervention group (n= 21, age= 65.3± 2.79) and a control group (n=18, age=65.3 ±3.2). The intervention group underwent PR combined with CT and the control group underwent only PR, 3 times per week during 3 months. Spirometry, 6-minute walking tests (6MWT) and cognitive performances [Montreal cognitive assessments (MOCA) and P300 test] were evaluated. Measures were taken at baseline and after 3-months of training programs.

Results:We showed a significant improvement of the 6MWT distance after the rehabilitation period in both groups (P< 0.001). Both groups showed a significant improvement (P< 0.001) in cognitive performance (score MOCA and P300 test) latency in three midlines electrodes. However, these improvements in cognitive performances were greater in the group that combined PR and CT.

Conclusion:The PR improves cardio respiratory and cognitive parameters however the use of CT added to PR is more effective in improving cognitive abilities than PR alone for COPD patients.
