Brief summary
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.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Walking Ability Questionnaire | The test will be conducted twice, with the second session scheduled 3-10 days after the first session | Walking Ability Questionnaire consisting of 19 items related to daily walking activities to assess community ambulation |
| Community Walking Speed | The test will be conducted twice, with the second session scheduled 3-10 days after the first session | Participants will complete an approximately 400-meter walking task |
| Taiwan Chinese Version of the Falls Efficacy Scale | The test will be conducted twice, with the second session scheduled 3-10 days after the first session | Participants will rate their level of concern about falling while performing 16 activities using a 4-point Likert scale to evaluate fall risk |
| Dynamic Visual Acuity Test | The test will be conducted twice, with the second session scheduled 3-10 days after the first session | Using Dynamic Visual Acuity Test to evaluate vestibulo-ocular reflex function |
