Description
Background and Purpose— There is limited conclusive data on both pharmacological and holistic treatment options to improve cognition in adults after stroke. In particular, there is lacking evidence for cognitive rehabilitation in the subacute and chronic phases when cognitive impairment may be more perceptible. In this meta-analytic review, our primary objective was to determine the cognitive effects of aerobic exercise on post-stroke adults in the post-acute phases. Secondary objectives were to investigate the differential effects of aerobic exercise on sub-domains of cognitive function.
Methods— Data were extracted and filtered from electronic databases PubMed (MEDLINE), CINAHL, Embase, PsycINFO, and Scopus. Intervention effects were represented by Hedges’ g and combined into pooled effect sizes using random effects models. Heterogeneity was evaluated using the Chi-squared (Q) and I-squared statistics.
Results— Five studies met inclusion criteria, representing data from 182 participants. The primary analysis produced a positive overall effect of aerobic exercise on cognitive performance (Hedges’ g [95% confidence interval]= 0.42 [0.007–0.77]). Effects were significantly different from zero for aerobic interventions combined with other physical activity interventions (Hedges’ g [CI] =0.59 [0.26 to 0.92]), but not for aerobic interventions alone (P= 0.40). In specific subdomains, positive moderate effects were found for global cognitive function (Hedges’ g [CI] =0.79 [0.31 to 1.26]) but not for attention and processing speed (P=0.08), executive function (P= 0.84), and working memory (P=0.92).
Conclusions— We determined that aerobic exercise combined with other modes of training produced a significant positive effect on cognition in adults after stroke in the subacute and chronic phases. Our analysis supports the use of combined training as a treatment option to enhance long-term cognitive function in adults after stroke. Further research is needed to determine the efficacy of aerobic training alone.

Description
The maximal amount of oxygen a person’s body can use while exercising is their VO2max. It is important to test VO2max in chronic stroke survivors who experience stroke-related deficits. The American College of Sports Medicine defines criteria for determining if a VO2max was reached. These criteria appear not to be applicable for this population. We explored an alternative set of criteria that appears more appropriate. Criteria for VO2max testing post-stroke should be further tested and defined.

Description
Stroke is the fifth most common cause of death in America and a leading cause of long-term adult disability, affecting more than 795,000 people a year ("American Stroke Association: A Division of the American Heart Association"). Many of these individuals experience persistent difficulty with the execution of daily tasks as a direct consequence of a stroke. A key factor in the successful recovery of a stroke survivor is rehabilitation. Rehabilitation sessions can start within two days of the stroke if the patient is in stable condition, and often continues long after their release from the hospital ("American Stroke Association: A Division of the American Heart Association"). The rehabilitation sessions are driven by a team of rehabilitation care professionals which includes, but is not limited to a physical therapist, occupational therapist, and speech-language pathologist. These professionals are available to the stroke survivor as resources to assist in developing and organizing ways to achieve independence as opposed to dependence. Ultimately, a stroke survivor’s family typically provides the most important long-term support during recovery and rehabilitation ("American Stroke Association: A Division of the American Heart Association"). However, there is very little research that focuses on the impact that local family can have on the stroke survivor’s establishment and achievement of goals throughout their recovery and rehabilitation. This study examines this gap in knowledge.
