Older adults in cardiac rehabilitation: a new strategy for enhancing physical function

PURPOSE: This study contrasted the effect of a group-mediated cognitive-behavioral intervention (GMCB) versus traditional cardiac rehabilitation (CRP) upon changes in objective and self-reported physical function of older adults mean (SD) age of 64.7 (7.5) yr after 3 months of exercise therapy. METHODS: This randomized clinical trial enrolled 147 participants who were eligible for inclusion into cardiac rehabilitation. Baseline to 3-month changes in self-reported and performance related measures of physical function were assessed using a physical functioning questionnaire, a 6-min walk test, and measured MET levels. RESULTS: Paired t-tests revealed that participants made improvements in all measures across the first 3 months of the study, irrespective of group treatment (P 0.05); however, the lower functioning participants in the GMCB intervention experienced greater improvements in self-reported physical function than those in CRP (P < 0.05). CONCLUSIONS: Exercise therapy is a valuable intervention for improving physical function of older adults with cardiovascular disease (CVD) and those at increased risk for CVD. Baseline level of physical function and gender are important variables to consider when studying the relationship between exercise therapy and improvements in physical function.
