About this study
Official title: Reliability of Community Ambulation Assessments, Taiwan Chinese Version of Falls Efficacy Scale, and Dynamic Visual Acuity Test in Individuals With Chronic Stroke
Nearly half of individuals with stroke experience limitations in community ambulation, and 35.7% of community-dwelling stroke survivors experienced falls while walking, indicating that falls are common during routine daily activities in community settings. Patla (1999) proposed that community mobility is influenced by eight factors: ambient conditions, terrain characteristics, external physical load, attentional demands, postural transitions, traffic level, time constraints, and walking distance. This framework suggests that community ambulation requires consideration of multiple physiological domains as well as environmental factors. However, current assessments of community ambulation primarily rely on indoor walking speed as an indicator, which may be insufficient to fully evaluate patients' community ambulation ability. Previous studies have not yet established the reliability of community ambulation assessments such as the Walking Ability Questionnaire, community walking speed, and the Falls Efficacy Scale (Taiwan Chinese version)-in individuals with chronic stroke. Additionally, stroke survivors often demonstrate insufficient integration of vestibular information, which may affect gait performance through impaired dynamic visual acuity. Therefore, this study aims to investigate the reliability of community ambulation assessments and dynamic visual acuity testing in individuals with chronic stroke.

What is being measured
The primary outcome is the main question the study is designed to answer.
Walking Ability Questionnaire
Walking Ability Questionnaire consisting of 19 items related to daily walking activities to assess community ambulation
Measured: The test will be conducted twice, with the second session scheduled 3-10 days after the first session
Community Walking Speed
Participants will complete an approximately 400-meter walking task
Measured: The test will be conducted twice, with the second session scheduled 3-10 days after the first session
Taiwan Chinese Version of the Falls Efficacy Scale
Participants will rate their level of concern about falling while performing 16 activities using a 4-point Likert scale to evaluate fall risk
Measured: The test will be conducted twice, with the second session scheduled 3-10 days after the first session
Dynamic Visual Acuity Test
Using Dynamic Visual Acuity Test to evaluate vestibulo-ocular reflex function
Measured: The test will be conducted twice, with the second session scheduled 3-10 days after the first session
