Resumen
Objectives To review intervention programs that measure gait to investigate what features of the intervention may contribute to improving gait in older adults with cognitive impairment or dementia.
Design Systematic review using Medline, Cinahl, Scopus, PsychInfo, Amed, Embase, Web of Science, and PubMed for original research published in English between January 1, 2000, and July 23, 2018, to identify interventional controlled trials. Narrative synthesis was undertaken.
Results Of 6,379 citations, 36 articles met inclusion criteria. Interventions were categorized as medication or medical devices (8 studies), exercise (19 studies), and exercise plus cognitive training (9 studies). Antidementia medication may improve gait variability in people with Alzheimer's disease. Exercise programs focusing on strength and balance training, especially when combined with functional mobility training, improve gait in people with mild cognitive impairment or dementia. Exercise plus cognitive training programs combining strength and balance training, functional mobility training, and training on attention and executive function also improve gait.
Conlusion Physical and cognitive factors affect gait performance, and both should be addressed in intervention programs. Physical exercises including functional mobility training, especially walking, have better results than physical programs with only static, resistance, and flexibility training. Cognitive intervention should be concomitant with physical exercises rather than separate, with a focus on attention and executive function. Combining physical training with cognitive training in a functional context may assist older adults with cognitive impairment generalize from training to everyday activity.
