Our study investigate the relationship between cognition and functional mobility during a structured grocery shopping performance using wearable technology in older adults with mild cognitive impairment (MCI) and cognitively unimpaired (CU). In this study, participants performed five structured grocery shopping trials of collecting eight shopping list items in a simulated physical grocery store. Inertial measurement unit data from the head and lumbar spine was associated with cognitive performance from the NIH Toolbox Cognition Battery. Objective measurements of movement using wearable technology during real-world activities, such as grocery shopping, may be an opportunity for digital biomarkers of cognitive and physical function.

Learning Objectives:

To describe the grocery shopping performance difference between those with mild cognitive impairment and cognitively unimpaired older adults
To describe the relationship between cognition and grocery shopping performance
To decribe the potential benefits of wearable technology in quantifying the performance of instrumental activities of daily living, such as grocery shopping
