Supplementary Information Files for: Does physical exercise improve the capacity for independent living in people with dementia or mild cognitive impairment: an overview of systematic reviews and meta-analyses Objective: To summarise existing systematic reviews which assessed the effects of physical exercise
on activities of daily living, walking, balance and visual processing in people with dementia or mild
cognitive impairment
Methods: In this overview of systematic reviews and meta-analyses, seven electronic databases were
searched to identify eligible reviews published between January 2015 and April 2021.
Results: A total of 30 systematic reviews were identified and included in the overview. The most
frequent type of exercise for the intervention group was multimodal exercises. Mind-body exercises,
exergames, dance intervention and aerobic exercise were other exercise types. Most of the reviews
reported that exercise is significantly effective for improving activities of daily living (SMD 95%CI, from
0.27 to 1.44), walking (SMD 95%CI, from 0.08 to 2.23), balance (SMD 95%CI, from 0.37 to 2.24) and
visuospatial function (SMD 95%CI, from 0.16 to 0.51), which are among the most leading determinants
of independent living in individuals with dementia or mild cognitive impairment.
Conclusion: Evidence has shown that exercise (especially multicomponent exercise programmes
including cognitive, physical and multitasking exercises) with sufficient intensity improves the activities of daily living skills. Exercise also improves walking, balance and visual processing, which can
provide a more independent life for people with dementia and mild cognitive impairment. Cognitively
impaired people should therefore be encouraged to exercise regularly in order to be more
independent.
