摘要

This study, a quasi-experimental, one-group pretest-posttest design, evaluated the effects on cognitive functioning and cardiorespiratory fitness of 8-week interventions (aerobic exercise alone and aerobic exercise and cognitive training combined) in patients with chronic stroke and cognitive impairment living in the community (participants: n=14, 61.93 +/- 9.90 years old, 51.50 +/- 38.22 months after stroke, n=7 per intervention group). Cognitive functions and cardiorespiratory fitness were evaluated before and after intervention, and at a 3-month follow-up visit (episodic memory: revised-Hopkins Verbal Learning Test; working memory: Brown-Peterson paradigm; attention omission and commission errors: Continuous Performance Test; cardiorespiratory fitness: peak oxygen uptake during a symptom-limited, graded exercise test performed on a semirecumbent ergometer). Friedman's two-way analysis of variance by ranks evaluated differences in score distributions related to time (for the two groups combined). Post-hoc testing was adjusted for multiple comparisons. Compared with before the intervention, there was a significant reduction in attention errors immediately following the intervention (omission errors: 14.6 +/- 21.5 vs. 8 +/- 13.9, P=0.01; commission errors: 16.4 +/- 6.3 vs. 10.9 +/- 7.2, P=0.04), and in part at follow-up (omission errors on follow-up: 3.4 +/- 4.3, P=0.03; commission errors on follow-up: 13.2 +/- 7.6, P=0.42). These results suggest that attention may improve in chronic stroke survivors with cognitive impairment following short-term training that includes an aerobic component, without a change in cardiorespiratory fitness. Randomized-controlled studies are required to confirm these findings. Copyright (C) 2016 Wolters Kluwer Health, Inc. All rights reserved.
