Balance and cognitive impairments which are common with aging often coexist, are
prognostic of future adverse health events, including fall injuries.
Consequently, dual-task assessment programs that simultaneously address both
stability and cognition are important to consider in rehabilitation and benefit
healthy aging. The objective of this study was to establish test-retest
reliability and construct validity of a dual-task computer game-based platform
(TGP) that integrates head tracking and cognitive tasks with balance activities.
Thirty healthy, community-dwelling individuals median age 64 (range 60-67) were
recruited from a certified Medical Fitness Facility. Participants performed a
series of computerized head tracking and cognitive game tasks while standing on
fixed and sponge surfaces. Testing was conducted on two occasions, one week
apart. Moderate to high test retest reliability (ICC values of 0.55-0.75) was
observed for all outcome measures representing balance, gaze performance,
cognition, and dual-task performance. A significant increase in center of foot
pressure (COP) excursion was observed during both head tracking and cognitive
dual-task conditions. The results demonstrate the system's ability to reliably
detect changes related to specific and integrated aspects of balance, gaze, and
cognitive performance.
