简要总结
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.

结局指标
主要结局
Motor Task Performance Accuracy
时间窗: Immediately after the experimental session
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.
