The effect of group exercises on balance, mobility, and depressive symptoms in older adults with mild cognitive impairment: a randomized controlled trial

摘要

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 ?
