Topic: Risk, prevention and care in population studies
Background Reliability of quantitative gait assessment while dual-tasking (walking while doing a secondary task such as talking) in people with cognitive impairment is unknown. Dual-tasking gait assessment is becoming highly important for mobility research with older adults since better reflects their performance in the basic activities of daily living. Our purpose was to establish the test-retest reliability of assessing quantitative gait variables using an electronic walkway in older adults with mild cognitive impairment (MCI) under single and dual-task conditions.
Key findings
- Dual-tasking gait assessment is becoming highly important for mobility research with older adults since better reflects their performance in the basic activities of daily living.
- Our purpose was to establish the test-retest reliability of assessing quantitative gait variables using an electronic walkway in older adults with mild cognitive impairment (MCI) under single and dual-task conditions.
- Methods The gait performance of 11 elderly individuals with MCI was evaluated using an electronic walkway (GAITRite System) in two sessions, one week apart.
- Six gait parameters (gait velocity, step length, stride length, step time, stride time, and double support time) were assessed under two conditions: single-task (sG: usual walking) and dual-task (dG: counting backwards from 100 while walking).
Why it matters
This reliability study tested quantitative gait assessment while dual-tasking in 11 older people with mild cognitive impairment using an electronic walkway. It is about the reliability of a measurement method and does not test any treatment, so it says nothing about curing or preventing Alzheimer's disease.
