An interventional study of Visual Aids(Photos, Videos, and Pictograms) in Stroke, sponsored by Jaegyeong Lee. Completed at 1 site in South Korea. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2025-11-25.
Sponsored by Jaegyeong Lee · Not applicable, Interventional, and Treatment
The goal of this interventional study is to learn how different types of visual aids-photos, videos, and pictograms-help people with stroke understand and perform simple physical movements. The researcher wants to find out which type of visual aid is most helpful and easiest to understand for stroke rehabilitation.
To take part, participants must be able to stand for at least one minute without help and understand simple instructions.
The main questions this study aims to answer are:
The researcher will compare how each type of visual aid affects movement performance and participants' responses.
Participants will:
7,286 studies on the registry are indexed under Stroke; 2,013 are open to participants now.
This study's enrollment of 50 is close to the median of 50 across 5,366 interventional studies indexed under Stroke.

Exclusion Criteria:
Behavioral: Visual Aids(Photos, Videos, and Pictograms)
Participants will be presented with three types of visual instructional aids: photographs, videos, and pictograms, via a laptop or tablet. Each participant will perform three motor tasks, each paired with a different visual aid, assigned in random order using a Latin Square design. Each task takes approximately 3 minutes, followed by 1 minute of rest. After completing all tasks, participants will complete a 5-minute survey about their understanding, preference, and perceived cognitive load. The total session lasts about 20 minutes.
Motor Task Performance Accuracy
Motor task performance accuracy will be assessed using a checklist developed by the researchers, considering task characteristics and learning effects. Each movement consists of 6 key performance elements, scored as 0 (not performed) or 1 (performed accurately), with a maximum of 6 points per task. All performances will be video recorded, and three trained raters will independently score the recordings. Inter-rater reliability will be evaluated using the Intraclass Correlation Coefficient (ICC) based on total scores.
Time frame: Immediately after the experimental session
Number of Replays
The number of times the participant presses the replay button to review the visual instructional material before performing the task will be automatically recorded. This measure will be stored using PsychoPy 2025.1.1 (Open Science Tools Ltd., Nottingham, UK).
Time frame: During each task trial (approximately 3 minutes per task)
Number of Hesitations
The number of hesitations will be counted during motor task performance. A hesitation is defined as a pause lasting more than 1 second, re-checking the visual aid, or modifying the movement. This measure indirectly reflects the participant's movement fluency and level of cognitive certainty. All performances will be video recorded and independently reviewed by three trained raters. Inter-rater reliability will be assessed using the Intraclass Correlation Coefficient (ICC 3,k).
Time frame: Immediately after the experimental session (video review)
Understanding of Visual Aids
Participants will rate how helpful each type of visual aid (photo, video, pictogram) was for understanding the motor task. A 5-point Likert scale will be used, where 1 indicates "Not helpful at all" and 5 indicates "Very helpful." Participants will complete this rating immediately after completing each task.
Time frame: Immediately after the experimental session
Preference for Visual Aids
Participants will indicate which of the three visual instructional aids (photos, videos, pictograms) they found easiest to understand. This measure captures participants' relative preference for the visual materials after performing the motor tasks.
Time frame: Immediately after the experimental session
Perceived Cognitive Load
The degree of mental effort experienced by participants while performing the motor tasks with each type of visual instructional material will be assessed. A pictorial 9-point Likert scale will be used, where a score of 1 indicates "not difficult at all" and a score of 9 indicates "very difficult"
Time frame: Immediately after the experimental session
