About this study

Official title: A Comparison of Visual Aids for Stroke Rehabilitation: Photos, Videos, Pictograms

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:

  • Which type of visual aid (photo, video, or pictogram) helps participants perform movements more accurately?
  • Which visual aid do participants find the easiest to understand and prefer?
  • How much mental effort (cognitive load) do participants feel when using each type of visual aid?
  • Do the effects of visual aids vary depending on stroke type, brain lesion location, or time since stroke?

The researcher will compare how each type of visual aid affects movement performance and participants' responses.

Participants will:

  • View three types of visual aids (photo, video, pictogram) and perform specific physical tasks based on each.
  • Have their movement performance recorded using a video camera.
  • Complete a short survey after the tasks to rate their understanding, preferences, and cognitive effort.
  • Take part in a single session that lasts about 20 minutes in a quiet room within the hospital.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Visual Aids(Photos, Videos, and Pictograms)Behavioural

    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.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. 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.

    Measured: Immediately after the experimental session

Secondary outcomes (5)
  1. 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).

    Measured: During each task trial (approximately 3 minutes per task)

  2. 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).

    Measured: Immediately after the experimental session (video review)

  3. 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.

    Measured: Immediately after the experimental session

  4. 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.

    Measured: Immediately after the experimental session

  5. 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"

    Measured: Immediately after the experimental session

Questions about this trial

What is this clinical trial studying?

A study testing Visual Aids(Photos, Videos, and Pictograms) in people with Stroke, run by Jaegyeong Lee at 1 site in South Korea.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 25 Nov 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in South Korea. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Motor Task Performance Accuracy (time frame: Immediately after the experimental session). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 25 Nov 2025.
