Oral Screens in Post Stroke Training
Stroke is a common disease in older people, and often leads to various degrees of disability. Dysphagia is one such consequence which is associated with aspiration pneumonia and malnutrition. There are studies showing that oral screen-training may reduce dysphagia, but the method is insufficiently evaluated. Since treatment with an oral screen is easy, relatively quick and cheap, it is of high relevance to perform a strict and unbiased study to assess the feasibility and efficacy of the intervention. Thus, the aim of the present study is to evaluate the effect of daily oral screen training in post-stroke patients with dysphagia.
A randomized controlled clinical study will be performed in subjects who have had a first stroke 8-12 months earlier and suffer from dysphagia. The intervention consists of daily oral screen training for 3 months. In total 70 subjects will be randomized to intervention or control. The changes in swallowing capacity is the main outcome, and secondary outcomes are subjective swallowing problems, lip force, chewing function and quality of life.
Improved oral motor function and decreased dysphagia in post-stroke patients will result in an improved quality of life for the individual, and also reduce hospitalization and health care costs.

Description détaillée
Project plan Population: Patients are recruited from the hospital Stockholms Sjukhem. When discharged, or 6-7 months after stroke, the patients are informed about the study. All positive answers are registered in a coded list. Patients are contacted by the investigators around eight months after the stroke. Patients are included in the study after informed consent, and if the inclusion criteria are fulfilled.
Inclusion criteria: ≥ 65 years of age. First stroke 8-12 months earlier. Remaining subjective and objective swallowing difficulties. Can eat. Can perform the training by himself/herself or with assistance. Natural teeth corresponding to category A according to Eichner's index.
Exclusion criteria: Moderate to severe impressive aphasia: <4.0 points by A-ning (Aphasia screening tool). Moderate to severe cognitive impairment: <23 points by MoCA (Montreal Cognitive Assessment). Unilateral neglect according to the baking tray task.
Procedure: The speech therapist screens the patient with the instruments A-ning, MoCA and Baking tray task. The dentist categorizes their dental status according to Eichner's index. Patients who do not fulfill inclusion criteria are excluded.
The patients are randomized to intervention or control group by central randomization.
At baseline, the patients in the intervention group receive an oral screen (IQoroTM) and get oral and written instructions on how to use it. They are instructed to train three times per day with an effective training time of 1.5 minutes, and to record sessions in a training diary. The patients in the control group do not get any intervention, but will be offered the corresponding training after the end of the study.
At baseline, 1.5 (intervention group only) and 3 months following intervention onset, lip force, swallowing capacity and chewing function are determined. At baseline and 3 months, oro-facial functions are screened with NOT-S and subjective swallowing problems with EAT-10 (Eating assessment tool). In order to relate these specific oral and swallowing instruments to the patient's life situation, we also include the validated instruments ESAS (Edmonton symptom assessment scale) and LiSat (Life Satisfaction) at baseline and 3 months.
Compliance in the intervention group will be evaluated by a training diary. Methods: Lip force is determined with an oral screen in the oral cavity. A hand held digital force gauge is linked to the oral screen with a wire. The patient is instructed to keep the oral screen in place as long as possible while the wire is stretched. The maximum force during tension is recorded three times.
Chewing function is evaluated with regard to bolus formation and mixing efficiency, by the use of a two-colored wax or chewing gum. The shape of the bolus and how well the colors are mixed after 30 chewing cycles is determined by visual assessment and colorimetric measures.
Swallowing capacity test (SCT) is preceded by a water swallowing test with 3-5 tea spoons of water in 4-5 rounds, in order to secure that the SCT is safe to perform. SCT: The patient is instructed to drink 150 ml of water. Swallowing speed is expressed as ml/s. Less than 10 ml/s is considered as an index of abnormal swallowing.
Power: Based on 10 ml/s as the lower limit of normal swallowing speed, we assess that 54 subjects are needed to finish the study. The estimation is made on the basis of a previous study. With 54 subjects, we will be able to determine a 40% higher proportion in the intervention group reaching 10 ml/s in SCT after finishing the training program, with 80% power and significance level 5%. To compensate for expected drop outs, we aim to recruit 35 subjects per group.
It is estimated that it will take about one year to recruit all participants to the study.
