The aim of this study was to systematically review the applicability
(attendance, achieved intensity, adverse events) and effects of physical exercise
on physical functions, cognitive functions, and activities of daily living among
people with dementia. DESIGN: : Randomized controlled trials were identified in
PubMed, the Cumulative Index to Nursing and Allied Health, the Allied and
Complementary Medicine Database, and the Cochrane Library on August 30 and
September 1, 2010, according to predefined inclusion criteria. Two reviewers
independently extracted predetermined data and assessed methodologic quality.
RESULTS: : A qualitative analysis was performed, including ten studies. Most
participants were people with Alzheimer disease in residential care facilities.
Four studies reached "moderate" methodologic quality, and six reached "low." The
studies of moderate quality evaluated the effects of combined functional
weight-bearing exercise, combined functional and nonfunctional exercise, and
walking exercise. CONCLUSIONS: : Among older people with Alzheimer disease in
residential care facilities, combined functional weight-bearing exercise seems
applicable for use regarding attendance and adverse events, and there is some
evidence that exercise improves walking performance and reduces the decline in
activities of daily living. Furthermore, there is some evidence that walking
exercise performed individually reduces decline in walking performance, but
adverse events need to be evaluated. Among older people with various types of
dementia disorders who are staying in a hospital, there is some evidence that
combined functional and nonfunctional exercise over 2 wks has no effect on
mobility. It seems important that the interventions last for at least a few
months and that the exercises are task-specific and are intended to challenge the
individual's physical capacity. Among older people with unspecified dementia
disorders in residential care facilities, there is some evidence that walking
exercise performed at a self-selected speed has no effect on cognitive functions.
Whether physical exercise can improve cognitive functions among people with
dementia remains unclear because studies evaluating this have either been of low
methodologic quality or used an intervention of presumably insufficient
intensity. There is a need for more studies of high methodologic quality,
especially among people with dementia disorders other than Alzheimer disease.
