About

This study tests an innovative system and service for collecting objective, consistent, and in-community gait parameters suitable for use as AD/ADRD biomarkers. The system is designed to be affordable, scalable, and practical for longitudinal, unsupervised, in-community use by older adults, including those with dementia symptoms. This study will be performed in two parts and involves collecting gait data from participants using the leg module and insole device either (1) for several hours in a lab setting (in-lab testing) or (2) within their home and community for 1 week (in-community testing). Thirty people who are healthy, have mild cognitive impairment, or who have Alzheimer's disease or related dementia will be recruited to participate in the in-lab testing, in which they will perform walking tasks and cognitive testing for several hours within a lab environment. After completion of in-lab testing, 120 individuals who are healthy, have mild cognitive impairment, or who have Alzheimer's disease or related dementia will be recruited to participate in the in-community testing, in which they will wear the insole and ankle device within their community for 1-week for collection of gait data in real world settings.

Enrollment: 150 estimated patients

Sex: All

Ages: 55+ years old

Volunteers: Accepts Healthy Volunteers

Inclusion criteria

• Age 55 or older
• Ability to ambulate without the use of an assistive device. For this study, we will assume participants are ambulatory if they can complete the functional outcome measures (i.e., TUG) without the use of an assistive device
• Ability to understand and provide informed consent, or has a legally authorized representative (LAR) to provide consent on their behalf
• Ability to don and doff the insole and leg module independently or have assistance for the duration of the study

Exclusion criteria

• Non-English Speaking
• Use of ankle-foot orthosis for ambulation that prevents use of the system
• Self-reported acute thrombophlebitis including deep vein thrombosis
• Untreated lymphedema or lesion of any kind, swelling, infection, inflamed area of skin or eruptions on or near product use (foot and ankle)
• Untreated fractures in the foot and ankle
• Any other significant medical condition that may affect participation or performance in the study, as determined by investigators
