Summary
This study shows a reliable computerized dual-task treadmill walking assessment for older adults. The tool accurately measures gait and cognitive function, aiding in fall risk evaluation.
Area of Science:
- Gerontology
- Neuroscience
- Biomechanics
Background:
- Age-related decline in mobility and cognition increases fall risk and reduces physical activity.
- Dual-task (DT) assessments are crucial for evaluating individuals with mobility and cognitive challenges.
- Fall injuries in older adults significantly impact health and healthcare costs.
Purpose of the Study:
- To assess the test-retest reliability of a computerized DT treadmill walking protocol.
- To evaluate the concurrent validity of gait and visuospatial executive function measures.
- To examine the discriminative validity of DT conditions on gait and cognitive performance.
Main Methods:
- Twenty-five healthy older adults (median age 65) participated.
- Participants performed computerized visuomotor and visuospatial executive tasks during treadmill walking.
- Testing was conducted twice, one week apart, assessing gait and cognitive measures.
Main Results:
- Moderate to high test-retest reliability (ICC 0.65-0.88) was found for spatiotemporal gait variables.
- Moderate reliability (ICC 0.6-0.65) was observed for visuomotor and visuospatial executive performance.
- Significant dual-task effects were evident in both gait and cognitive performance measures.
Conclusions:
- The computerized DT treadmill walking assessment is reliable and reproducible for older adults.
- This tool can accurately record data for evaluating gait and cognitive function.
- The protocol expands standardized assessments for dual-task treadmill walking in older populations.
