About this study
Official title: A Randomized Controlled Trial Evaluating the Effect of a Semiotically-Optimized Video Education Model on Activities of Daily Living, Sleep Quality, Anxiety, Depression, and Patient Satisfaction in Post-Stroke Rehabilitation Patients
Stroke is a leading cause of death and disability worldwide. Many stroke survivors face difficulties with daily activities, sleep problems, anxiety, and depression during recovery. Health education videos can help patients learn about rehabilitation, but standard videos often contain too much information and are hard for patients to follow. This study aims to test whether using semiotics - the science of signs and symbols - to redesign health education videos can help stroke patients better comprehend and apply rehabilitation instructions. The study is designed to include 200 stroke patients at Siping Central Hospital in Jilin Province, China. Patients will be randomly assigned to either the semiotic-optimized video group or the standard health education video group. Outcome measures, including activities of daily living, sleep quality, anxiety, depression, and satisfaction with care, will be assessed before and after the intervention to evaluate the effectiveness of the optimized video education model.
Read the detailed description
Stroke rehabilitation requires patients to acquire and retain complex self-care knowledge, yet cognitive impairments following stroke often limit their ability to process standard verbal and written health education. Conventional video-based education, while beneficial, frequently presents information in ways that overlook patients' cognitive load and perceptual limitations. Semiotic theory - the systematic study of how signs, symbols, and multimodal cues construct meaning - offers a framework for redesigning educational content to enhance comprehension, retention, and behavioral adoption.
This is a randomized controlled trial conducted at the Rehabilitation Department of Siping Central Hospital, with the intervention period scheduled from January to December 2023. The intervention was developed by a multidisciplinary team of eight specialists and nurses from the Rehabilitation and Neurology Departments. Twenty-two educational videos were produced across three domains: rehabilitation science, exercise guidance, and dietary advice. Each video averaged five to eight minutes in duration. In the experimental group, videos were redesigned using semiotic principles: key rehabilitation actions were highlighted through local magnification with bold, red subtitles and auditory cues; incorrect postures were filmed and contrasted with correct demonstrations using comparative visual cues; and a curated music library was integrated to support relaxation and sleep. Video feedback techniques were also employed, including on-site assessment of movement accuracy and post-training questioning to evaluate knowledge retention. The intervention was delivered twice daily under nursing supervision throughout the 28-day inpatient rehabilitation period.
The control group received standard care with the same set of rehabilitation videos delivered through routine face-to-face guidance, without semiotic optimization or structured video feedback. The primary objective is to evaluate whether the semiotically-optimized video education model can improve activities of daily living compared to standard video education. Secondary objectives will assess changes in sleep quality, anxiety, depression, and patient satisfaction.

What is being measured
The primary outcome is the main question the study is designed to answer.
Change in Activities of Daily Living (ADL)
Modified Barthel Index (MBI), The MBI comprises 10 items assessing ADL, with a total score ranging from 0 to 100. Higher scores indicate better independence in daily living activities.
Measured: Baseline and Day 28
Secondary outcomes (4)
Change in Sleep Quality
Pittsburgh Sleep Quality Index (PSQI), The PSQI consists of 18 items assessing sleep quality over a one-month interval. The global score ranges from 0 to 21. Lower scores indicate better sleep quality, whereas higher scores indicate worse sleep quality.
Measured: Baseline and Day 28
Change in Anxiety
Beck Anxiety Inventory (BAI), The BAI consists of 21 self-report items, with a total score ranging from 0 to 63. Higher scores indicate more severe anxiety.
Measured: Baseline and Day 28
Change in Depression
Chinese Version of the Beck Depression Inventory, 2nd edition (BDI-Ⅱ-C), The BDI-II-C consists of 21 items assessing depressive symptoms, with a total score ranging from 0 to 63. Higher scores indicate more severe depression.
Measured: Baseline and Day 28
Patient Satisfaction
Self-developed Inpatient Satisfaction Questionnaire, The questionnaire consists of 10 items rated on a 5-point Likert scale, yielding a total score ranging from 10 to 50. Higher scores indicate better patient satisfaction.
Measured: Day 28
