Safety and indoor mobility in the elderly.

Area of Science:

• Gerontology
• Environmental Health
• Biomechanics

Background:

• Assessing the safety and accessibility of residential environments for the elderly is critical for promoting independent living.
• Falls and mobility issues are significant concerns for older adults, often linked to environmental hazards.

Purpose of the Study:

• To identify environmental factors affecting the safe and easy mobility of elderly individuals.
• To provide a basis for developing and adapting living spaces to better support the aging population.

Main Methods:

• Field study involving daily activity assessment, fall history inquiry, performance examination, and residential environment safety surveys in 70-80-year-old subjects (N=15).
• Laboratory study with 70-80-year-old subjects (N=55) performing gait analysis on a test track, including line and zigzag walking tasks.
• Evaluation of environmental risk levels and subject performance in reaching tasks and gait stability.

Main Results:

• Most surveyed homes presented moderate risk levels for elderly residents.
• Elderly subjects experienced difficulties reaching high and low objects, indicating accessibility issues.
• Gait instability and errors during walking tasks (line, zigzag) were observed, influenced by environmental elements and task demands.
• Subjects found slightly lower stairs easier to navigate, suggesting a need for revised building standards.

Conclusions:

• Current residential environments require updated criteria and regulations to ensure the safety of the elderly.
• Significant improvements in indoor mobility safety for older adults are achievable through targeted environmental modifications.
