OBJECTIVE: To evaluate the effect of exercise and cognitive training on falls
reduction and on factors known to be associated with falls among
community-dwelling older adults with mild cognitive impairment (MCI). DATA
SOURCES: Seven databases (PubMed, CINAHL, Cochrane Library, Web of Science,
ProQuest, ProQuest Dissertations and Theses, Digital Dissertation Consortium) and
reference lists of pertinent articles were searched.
STUDY SELECTION: Randomized
controlled trials (RCTs) on the effect of exercise, cognitive training, or a
combination of both on falls and factors associated with falls such as balance,
lower limb muscle strength, gait, and cognitive function among community-dwelling
older adults with MCI were included. DATA EXTRACTION: Data were extracted using
the modified Joanna Briggs Institute Meta-Analysis of Statistics Assessment and
Review Instrument (JBI-MAStARI) tool. Study quality was assessed using the
JBI-MAStARI appraisal instrument. DATA SYNTHESIS: Seventeen RCTs (1679
participants; mean age +/- SD, 74.4+/-2.4y) were included. Exercise improved gait
speed and global cognitive function in MCI; both are known factors associated
with falls. Cognitive training alone had no significant effect on cognitive
function, while combined exercise and cognitive training improved balance in MCI.
Neither fall rate nor the number of fallers was reported in any of the studies included. CONCLUSIONS: This review suggests that exercise, and combined exercise
and cognitive training improve specific factors associated with falls such as
gait speed, cognitive function, and balance in MCI.
Further research on the
direct effect of exercise and cognitive training on the fall rate and incidence
in older adults with MCI with larger sample sizes is highly recommended.
