Regular physical activity is vital for cardiovascular health. Time
spent in sedentary behaviors (eg, sitting, lying down) also is an independent
risk factor for cardiovascular disease. The pattern in which sedentary time is
accumulated is important-with prolonged periods of sitting time being
particularly deleterious. People with stroke are at high risk for cardiovascular
disease, including recurrent stroke. PURPOSE: This systematic review aimed to
update current knowledge of physical activity and sedentary behaviors among
people with stroke living in the community. A secondary aim was to investigate
factors associated with physical activity levels. DATA SOURCES: The data sources
used were MEDLINE, Cumulative Index to Nursing and Allied Health Literature
(CINAHL), Allied and Complimentary Medicine Database (AMED), EMBASE, and the
Cochrane Library. STUDY SELECTION: Studies involving people with stroke living in
the community and utilizing objective measures of physical activity or sedentary
behaviors were included. DATA EXTRACTION: Data were extracted by one reviewer and
checked for accuracy by a second person. DATA SYNTHESIS: Twenty-six studies,
involving 983 participants, were included. The most common measure of activity
was steps per day (22 studies), which was consistently reported as less than half
of age-matched normative values. Only 4 studies reported on sedentary time
specifically. No studies described the pattern by which sedentary behaviors were
accumulated across the day. Walking ability, balance, and degree of physical
fitness were positively associated with higher levels of physical activity.
LIMITATIONS: This review included only studies of people living in the community
after stroke who were able to walk, and the majority of included participants
were aged between 65 and 75 years of age. CONCLUSIONS: Little is known about the
time people with stroke spend being sedentary each day or the pattern in which
sedentary time is accumulated. Studies using objective, reliable, and valid
measures of sedentary time are needed to further investigate the effects of
sedentary time on the health of people with stroke.
