Abstract
OBJECTIVE:: To determine the effects of group exercises on balance, mobility, and depressive symptoms in community-dwelling older adults with mild cognitive impairment.
DESIGN:: Single blinded, randomized, matched pairs clinical trial.
SETTING:: Four primary healthcare units.
SUBJECTS:: Fifty-two sedentary subjects with mild cognitive impairment were paired (age, sex, body mass index, and Addenbrooke's Cognitive Examination Revised score), tested, and then randomized into an intervention group ( n = 26) and a control group ( n = 26).
INTERVENTION:: The intervention group performed strength (ankle weights, elastic bands, and dumbbells) and aerobic exercises (walking) in their communities' public spaces, twice a week (60 minutes each), during 24 weeks. The control group maintained its usual routine.
MAIN MEASURES:: Balance (Berg Balance Scale (BBS)), mobility (Timed Up and Go Test (TUG)), and depressive symptoms (Geriatric Depression Scale-15) were assessed before and after the intervention.
RESULTS:: Before the intervention, the two groups did not differ statistically. After, the intervention group showed significant improvement ( P < 0.05) in balance (before: 53 ± 3; after: 55.1 ± 1.1 points), mobility (before: 10.7 ± 2.9 seconds; after: 8.3 ± 2 seconds), and depressive symptoms (median punctuation (interquartile range) before: 4 (1.8-6); after: 2.5 (1-4)). The control group presented a significant increase in their depressive symptoms (median before: 3.5 (2-7.3); after: 4 (2-5.3)), while their balance and mobility showed no significant modification. Small effect sizes were observed in the intervention group and control group depressive symptoms, as well as in the control group's mobility and balance. Large effect sizes were observed the intervention group's mobility and balance.
CONCLUSION:: Group exercises improved balance, mobility, and depressive symptoms in community-dwelling older adults with mild cognitive impairment.
