Commentary on: Zhang W, Low LF, Gwynn JD, et al. Interventions to improve gait in older adults with cognitive impairment: a systematic review. J Am Geriatr Soc 2019;67;381–91.
Gait is not solely a biomechanical process. Cognitive factors need to be considered when employing interventions to improve gait in older people. Physical and cognitive factors affect gait performance, and both should be addressed in intervention programs. To improve gait in older people living with mild cognitive impairment, or the early stages of dementia, gait interventions should include strength, balance and functional mobility training in combination with cognitive control training.
The prevalence of gait and balance disorders significantly increases as a person grows older. These disorders affect around 10% people in their 60s and >60% of people in their 80s.
