简要总结
This study is being done to better understand how vestibular problems and thinking abilities (such as attention and mental flexibility) are related in older adults, and how doing a balance task and a thinking task at the same time affects their performance. Older adults will first complete questionnaires and simple paper-and-pencil tests of attention, memory, and mental rotation while seated. They will then perform standing balance tasks on a portable force platform under different conditions (eyes open, eyes closed, standing on a foam surface) and will repeat some of the thinking tasks at the same time. Next, participants will walk on a treadmill while wearing small motion sensors, both with and without added thinking tasks such as serial subtraction and digit reordering. The total testing time is about 90 minutes. Two groups will be included: healthy older adults and older adults who have had dizziness or falls in the past two years. By comparing these groups, the study aims to provide a basis for designing future dual-task assessment and training programs to reduce balance problems and falls in older adults.

结局指标
主要结局
Gait speed
时间窗: Baseline laboratory assessment (single visit in year 1)
Average forward velocity of whole-body progression during walking, calculated as total distance divided by time.
Stride length (m)
时间窗: Baseline laboratory assessment (single visit in year 1)
Linear distance between two consecutive initial contacts of the same foot.
Step width (m)
时间窗: Baseline laboratory assessment (single visit in year 1)
Mediolateral distance between consecutive foot placements, representing base of support during gait.
Cadence (steps/min)
时间窗: Baseline laboratory assessment (single visit in year 1)
Number of steps taken per minute during walking.
Step-to-step variability (%)
时间窗: Baseline laboratory assessment (single visit in year 1)
Variability of consecutive steps, typically quantified as the coefficient of variation of stride time or step length.
Trunk angular velocity (degrees/s)
时间窗: Baseline laboratory assessment (single visit in year 1)
Rate of change in trunk segment orientation over time, derived from rotational kinematics.
Trunk angular displacement (degrees)
时间窗: Baseline laboratory assessment (single visit in year 1)
Magnitude of trunk segment rotation relative to a reference orientation.
Center-of-mass displacement (m)
时间窗: Baseline laboratory assessment (single visit in year 1)
Spatial excursion of the body's center of mass, typically analyzed in anterior-posterior and mediolateral directions during standing.
Response time (s or ms)
时间窗: Baseline laboratory assessment (single visit in year 1)
Time elapsed between stimulus onset and initiation of a motor response.
