The investigators conduct a controlled prospective experimental intervention study to examine whether the use of a tongue brush (Orabrush) can improve the rate of aspiration pneumonia and dysphagia in patients with ischemic stroke. Secondary outcomes include the impact on bacterial tongue colonization, the Tongue Coating Index, and the length of stay of the patients.The patients will be recruited in the Stroke Unit of the Department of Neurology from November 2024 until approximately October 2026.
As part of a prospective controlled experimental intervention study, patients with ischemic stroke will be recruited in the Stroke Unit of the University Hospital Marburg, who are admitted between November 2024 and approximately October 2026. The primary objective of this study is to investigate the impact of a tongue brush (Orabrush) on the rate of aspiration pneumonia and dysphagia. Secondary outcomes include the analysis of bacterial tongue colonization, the Tongue Coating Index, and the length of stay of the patients. Key study parameters include the aspiration rate, the EAT-10, the GUSS, a tongue swab, and a photograph of the tongue to determine the Tongue Coating Index. Data will be collected on the day of admission and after a duration of 3-5 days. The study has been approved by the relevant ethics committee.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Routine Care Group | No Intervention | Patients in the Routine Care Group receive standard speech therapy during their inpatient stay. | |
| Tongue Brush Group | Experimental | Patients in the Tongue Brush Group receive standard speech therapy and additionally use the tongue brush twice daily for a period of 3-5 days during their inpatient stay. |
|
| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| Tongue Brush (Orabrush) | Device | Patients in this group uses the Tongue Brush (Orabrush) 2 times a day for a duration for 3-5 days until the follow-up-screening takes place. |
|
| Measure | Description | Time Frame |
|---|---|---|
| Rate of Aspiration Pneumonias | Evaluation of the Impact of a Tongue Brush on the Incidence of Aspiration Pneumonia in Patients with Ischemic Stroke. | From the date of first admission until discharge, with the occurrence of aspiration, within max. 4 weeks pneumonia documented at any point during the inpatient stay. |
| Severity of dysphagia measured by EAT-10 [score from 0-40] | This study aims to investigate whether the use of a tongue brush has an effect on the severity of dysphagia in ischemic stroke patients compared to the control group. The severity of dysphagia is quantified using the dysphagia screening tool EAT-10. The EAT-10 can have a score ranging from 0 to 40, with the severity of dysphagia increasing as the score rises. | EAT-10 is assessed on the day of admission and after a period of 3-5 days. |
| Severity of dysphagia measured by GUSS [score from 0-20] | This study aims to investigate whether the use of a tongue brush has an effect on the severity of dysphagia in ischemic stroke patients compared to the control group. The severity of dysphagia is quantified using the dysphagia screening tool GUSS. The GUSS can have a score ranging from 0 to 20, with the severity of dysphagia increasing as the score decreases. | GUSS is assessed on the day of admission and after a period of 3-5 days. |
| Measure | Description | Time Frame |
|---|---|---|
| Winkel Tongue Coating Index [Score from 0 to 12] | Determination of the Winkel Tongue Coating Index (WTCI) in ischemic stroke patients. For this purpose, the tongue is divided into six equal-sized quadrants, and each quadrant is assigned a score from 0 to 2, depending on the severity of tongue coating. In total, a score ranging from a minimum of 0 to a maximum of 12 points can be achieved across the six quadrants. A low score indicates very little tongue coating, while a high score reflects a significant amount of tongue coating. |

| The WTCI of the patients is determined on the day of admission and after 3-5 days. |
| Microbiological quantification of the tongue's bacterial load through the determination of colony-forming units (CFU) | A swab of the tongue is taken from patients with ischemic stroke, and a microbiological quantification of the bacterial load is performed. Depending on the level of CFU, the bacterial load is categorized into the semiquantitative parameters 'low,' 'moderate,' and 'high'. | Bacterial tongue colonization is assessed in the patients through swabbing on the day of admission and after 3-5 days. |
| Length of in-hospital stay in days | It is investigated how many days patients with ischemic stroke stay in the hospital and whether there is a significant difference in the length of stay between the control and intervention groups. | Duration of in-hospital stay, measured from the admission date to the discharge date, during the inpatient treatment period. The average length of stay is approximately 6 days, so a maximum time frame of 30 days is chosen for the survey. |
