Overview
Brief Summary
This cross-sectional study aims to investigate the prevalence of post-stroke visual dependence, and the effects of visual dependence on balance and gait. It also determines whether visual dependence could differentiate stroke patients with a history of falls from without.
Detailed Description
Stroke participants will be recruited to measure the level of visual dependence, muscle strength, neurological recovery, balance ability, vertigo symptom, gait pattern and activities of daily living. This will calculate the prevalence of post-stroke visual dependence, and investigate the negative impact of visual dependence on balance and walking functions. This also determines whether the value of visual dependence could differentiate stroke patients with a history of falls from without a history of falls.

Outcomes
Primary Outcomes
A history of falls
Time Frame: Baseline
Any falls in the past year (n). Fall is defined by the inadvertently coming to rest on the ground, floor or other lower level, excluding intentional change in position to rest in furniture, wall or other objects. More than once fall is identified as faller.
Postural visual dependence
Time Frame: Baseline
Postural sway will be measured using an accelerometer attached on the lower back when participants are looking at blank wall, eyes closed and looking at rotating visual background. Greater postural sway in conditions with eyes closed and rotating visual background corresponding to looking at blank wall represents the higher level of postural visual dependence.
Perceived visual dependence
Time Frame: Baseline
Perceived visual dependence will be assessed using a computerized Rod and Disc Test (RDT). Participants will adjust a tilted rod to their subjective visual vertical with rotating visual background. The error (degrees) between subjective visual vertical and gravitational vertical will be measured and represented as the level of visual dependence. Higher error indicates higher level of perceived visual dependence.
