Fig. 1From: A framework for secondary cognitive and motor tasks in dual-task gait testing in people with mild cognitive impairmentFramework for changes in gait velocity and cognitive cost across gait testing conditions. Note: Gait tests within the same level were not statistically different from one another. Gait velocity decreased on moving from level 1 to level 3. Cognitive cost increased on moving from level 1 to level 3Back to article page
