Effectiveness of Multicomponent Exercise Interventions in Older Adults With Dementia: A Meta-Analysis.


ABSTRACT:

Background and objectives

Multicomponent training (MT) combines aerobic, strength, postural, and balance exercises, and may be a promising intervention strategy for dementia. This meta-analysis study aims to systematize evidence concerning the effectiveness of MT in physical fitness, cognition, and functionality on activities of daily living (ADL) in older adults with dementia, and to identify moderation patterns regarding training variables.

Research design and methods

Four databases were systematically searched to locate potential trials through March 2019. A total of 2.312 records were identified and a final set of 17 manuscripts reviewed; of these, 6 satisfied all eligibility criteria.

Results

Samples sizes ranged from 27 to 170 participants; MT programs lasted between 4 weeks up to 12 months, took place from a daily basis to twice a week, and sessions ranged from 30-60 min. The TESTEX scale was used to analyze the methodological quality, and the funnel plots to assess risk of bias. This meta-analysis revealed that MT interventions benefit older adults with dementia regarding ADL's performance (ES= 0.313 [0.16 to 0.46]; p<0.01), but the evidence was not sufficiently robust to determine the effectiveness of MT on cognitive function and physical fitness, particularly, on agility.

Discussion and implications

MT may be an important non-pharmacological strategy to enhance ADL's functionality on older adults with dementia. Findings suggest that long-term interventions are more prevailing than high frequency and longer duration exercise sessions. Further evidence is needed for acknowledging its benefits in specific cognitive abilities and physical fitness. This meta-analysis is registered in PROSPERO (no. CRD42020141545).
