| dc.description.abstract | Gait performance in aging relies heavily on cognitive resources, yet the extent to which short-term interventions can mitigate dual-task costs in institutionalized populations remains understudied. This study aimed to compare single and dual-task gait performance between older adults with and without suspected cognitive impairment and to evaluate the effects of an 8-week multicomponent exercise program on functional mobility. Methods: Institutionalized older adults (n = 42) were stratified into two groups: suspected cognitive impairment (n = 26) and no suspected impairment (n = 16), based on MMSE and Clock Drawing Test screening. Participants performed the Timed Up and Go (TUG) and Dual-Task TUG (TUG-DT) at baseline and post-intervention. Results: At baseline, the suspected impairment group exhibited significantly poorer performance on both tests (p < 0.001) compared to the non-impaired group. Following the 8-week intervention, the suspected impairment group demonstrated large, significant improvements in both TUG (r = −0.73) and TUG-DT (r = −0.59), whereas the non-impaired group remained stable. Notably, while the single-task TUG showed the greatest responsiveness to the exercise program, the TUG-DT continued to reveal a significant cognitive-motor load. Conclusions: Multicomponent exercise effectively enhances functional mobility in cognitively vulnerable older adults, reversing declines in both single and dual-task conditions. Significance: These findings support the implementation of dual-task screening to unmask latent functional deficits and validate the use of accessible, short-term multicomponent exercise programs as a vital strategy to preserve autonomy in institutionalized older adults. | eng |
