Task switching after stroke.

BACKGROUND AND PURPOSE: Task switching is a cognitive skill that may be compromised after brain damage. The purposes of this study were to examine task-switching abilities in the subacute phase after stroke, to determine whether a switching task under endogenous or internal control is more difficult than a switching task under exogenous or cued control, and to determine whether deficits in switching attenuate in the first few months after stroke. SUBJECTS: The participants in this study were 46 adults with stroke and 38 adults without stroke. METHODS: Subjects performed 2 computer-based switching tasks, an alternating task that relied on endogenous control and a cued task that relied on exogenous control. Testing was done in subjects' homes at 1 and 3 months after stroke and at a 2-month interval for control subjects. Switch costs, or the difference between the no-switch condition and the switch condition, were calculated for accuracy and response time. RESULTS: Subjects in the stroke group had higher switch costs for accuracy than did subjects in the control group. The alternating task was more difficult than the cued task, with higher switch costs for accuracy and response time. The alternating task was particularly difficult for subjects in the stroke group, with high switch costs for accuracy. Both groups showed decreased response time switch costs at the second testing session. DISCUSSION AND CONCLUSION: Task switching, particularly if under endogenous control, is impaired in adults in the subacute phase after stroke. Clinicians should be aware of performance deficits that may relate to task switching.

Multidimensional exercise for people with Parkinson's disease: a case report.

The primary impairments associated with Parkinson's disease occur in combination with the secondary, preventable effects of immobility. A community-based fitness program may help increase activity and maintain function in people in the early or middle stages of the disease. This article describes a unique program designed to reduce fall risk and promote independent exercise for people with Parkinson's disease. Two 66-year-old males, both community ambulators and in early or middle stages of Parkinson's disease, participated in 3 months of various physical activities. Group balance classes were held twice weekly during the first month, participants joined a fitness center and self-directed their exercise program during the second month, and group Tai Chi classes were held twice weekly during the third month. At conclusion of the program, participants were given suggestions for continued physical fitness activities. After the 3-month program, improvements were noted for both individuals in functional reach, Timed Up and Go, and Berg Balance scores. Both participants continued to exercise regularly for at least 8 months following the program. Two individuals with Parkinson's disease demonstrated improvement in their balance test performance over a 3-month period. Perhaps most importantly, these participants independently continued exercising after completing this program.

Exercise-induced changes of the upper extremity in chronic stroke survivors.

Problems with daily activities due to decreased aerobic capacity and decreased strength are common in people who survive a stroke. Implementation of exercise for the upper extremity is challenging because of weakness and other impairments that limit performance of exercise activities. Although maximal exercise testing protocols are difficult to administer, submaximal testing may be a safe and effective means for prescribing exercise. Research studies have demonstrated that people with stroke can improve aerobic capacity and upper extremity muscle strength with exercise intervention, although the number of randomized controlled trials is limited and this area requires further investigation.
