Using a GPS Watch to Characterize Life-Space Mobility in Dementia: A Dyadic Case Study

Area of Science:

• Gerontology
• Nursing
• Rehabilitation

Background:

• Persons with dementia (PWD) often face challenges with navigation and out-of-home activities, impacting their independence.
• Life-space mobility (LSM) assessment is crucial for understanding functional levels and independence in PWD.

Purpose of the Study:

• To explore the feasibility of using a global positioning system (GPS) watch for measuring LSM in a Latino PWD.
• To assess the utility of wearable location tracking technology in dementia care.

Main Methods:

• A dyadic case study approach was employed.
• Data collection included a travel diary, LSM questionnaire, qualitative interviews, and GPS-based mobility tracking.
• GPS data characterized the PWD's outdoor trips and social activity patterns.

Main Results:

• GPS data revealed regular outdoor trips and social activity with daily variations.
• Qualitative interviews provided contextual insights into mobility patterns.
• The PWD and caregiver reported positive perceptions of the GPS watch for activity tracking.

Conclusions:

• Wearable GPS technology offers a viable method for accurate LSM assessment in PWD.
• This technology can inform nursing practice, policy, and research to enhance well-being and delay functional decline.
• GPS tracking supports improved care and independence for persons with dementia.
