Concurrent validity of the Groningen Meander Walking and Timed Up and Go tests in older adults with dementia

Effects of curved path walking compared to straight path walking in older adults with cognitive deficits: A systematic review and network meta‐analysis

“…Gait evaluation using a cognitive‐motor interference task is superior to gait evaluation using a single task for revealing a correlation with real cognition (de Cock et al., 2017; Hunter et al., 2018, 2020; Lee et al., 2019). It has been argued that a single task does not reflect actual daily life.…”

“…Older adults with cognitive impairment show decreased speed or additional steps when walking on curved or turning paths (Lee et al., 2019). This delay is because curved or turning paths require predictive control (McFadyen, 1991) and additional postural adjustment when estimating the future direction of walking as the path curves (Crenna et al., 2007).…”

“…Accordingly, curved path walking may be an effective task to assess the severity of physical and cognitive impairment in older adults with dementia (H.‐S. Lee et al., 2019).…”

“…Older adults with cognitive decline due to brain damage may have difficulty with curved path walking, because changing the direction requires a voluntary asymmetrical stepping response directly from the basal ganglia‐cortical loop while it is under strain of the attention demanding need for greater balance control (H.‐S. Lee et al., 2019). A slower rate of cognitive processing may interfere with centrally mediated motor coordination, resulting in slow or inaccurate motor response during curved path walking.…”

Correlation between Gait Speed and Velocity of Center of Pressure Progression during Stance Phase in the Older Adults with Cognitive Decline: A Pilot Study

“…The COP velocity during the mid-stance phase can be a key component to explain slower gait speed in older adults with cognitive decline [8,9]. Lee et al [10] suggested that assessment of gait speed could be an effective clinical tool for predicting cognitive decline.…”
