Using Sensor Graphs for Monitoring the Effect on the Performance of the OTAGO Exercise Program in Older Adults

Area of Science:

• Gerontology
• Rehabilitation Science
• Biomedical Engineering

Background:

• Falls are a significant risk for older adults, impacting mobility and independence.
• The OTAGO exercise program is a known fall prevention strategy.
• Limited research exists on its specific effects on mobility capacity and performance.

Purpose of the Study:

• To investigate the OTAGO exercise program's effect on mobility capacity.
• To assess the program's impact on daily living performance in older adults.
• To explore the use of motion sensors for performance monitoring.

Main Methods:

• Observational pilot study over 10 months with 15 pre-frail participants (mean age 84.6).
• Motion sensors used to monitor daily activity as a performance surrogate.
• Weighted directed multigraph analysis and least squares regression to quantify changes.

Main Results:

• Indication of a positive effect of the OTAGO program on mobility capacity in both intervention and control groups.
• Indication that the OTAGO program may reduce the decline in daily living performance.
• Pilot data suggests potential benefits for older adults' functional status.

Conclusions:

• The OTAGO program shows potential for enhancing mobility capacity and performance in older adults.
• Further research is needed to confirm causality due to the pilot nature of the study.
• Motion sensor data provides a novel approach to assess real-world performance changes.
