Owing to advancement of medical technology and current knowledge, the population has a longer life expectancy, leading to an increase in the proportion of elderly. Objective: The study aimed to investigate the effect of action observation (AO) combined with gait training on gait and cognition in elderly with mild cognitive impairment (MCI). Methods: Thirty-three participants were randomly allocated to action observation with gait training (AOGT), gait training (GT), and control (CT) groups. The AOGT and GT groups received a program of observation and gait training protocol with the same total duration of 65 min for 12 sessions. For the observation, the AGOT group watched a video of normal gait movement, while the GT group watched an abstract picture and the CT group received no training program. All participants were assessed for gait parameters during single-and dual-tasks using an electronic gait mat system and were assessed for cognitive level using the Montreal Cognitive Assessment (MoCA) at baseline, after training and at 1-month follow-up. Results: The results showed that the AOGT group had significant improvements in gait speeds during single-and dual-tasks, as well as better MoCA score, while the GT group had significant improvement only in gait speed. Conclusion: The adjunct treatment of AO with gait training provides greater benefits for both gait and cognitive performances in elderly with MCI.Mahidol UniversityMedicineNeuroscienceArticleSCOPUS10.1590/1980-57642020dn14-020004
