RESUMEN

INTRODUCTION: Dysphagia is a common and critical consequence of acquired brain injury (ABI) and can cause severe complications. Dysphagia rehabilitation is transforming from mainly compensatory strategies to the retraining of swallowing function using principles from neuroscience. However, there are no studies that map interventions available to retrain swallowing function in patients with moderate-to-severe ABI. OBJECTIVE: To systematically map the accessible research literature to answer the research question: Which non-surgical, non-pharmacological interventions are used in the treatment of dysphagia in patients with moderate and severe ABI in the acute and subacute phase? DESIGN: Scoping review based on the methodology of Arksey and O'Malley and methodological advancement by Levac et al. DATA SOURCES: MEDLINE, Embase, Cochrane Library, CINAHL, PsycINFO, Web of Science, OTseeker, speechBITE and PEDro were searched up until 14 March 2021. ELIGIBILITY CRITERIA: All studies reporting rehabilitative interventions within 6 months of injury for patients with moderate-to-severe ABI and dysphagia were included. DATA EXTRACTION AND SYNTHESIS: Data was extracted by two independent reviewers and studies were categorised based on treatment modality. RESULTS: A total of 21 396 records were retrieved, and a final of 26 studies were included. Interventions were categorised into cortical or non-cortical stimulation of the swallowing network. Cortical stimulation interventions were repetitive transcranial magnetic stimulation (rTMS) and transcranial direct current stimulation. Non-cortical were complex swallowing interventions, neuromuscular electrical stimulation, pharyngeal electrical stimulation (PES), sensory stimulation, strengthening exercises and respiratory muscle training. CONCLUSION: This scoping review provides an overview of rehabilitative dysphagia interventions for patients with moderate and severe ABI, predominantly due to stroke, in the acute and subacute phase. Positive tendencies towards beneficial effects were found for rTMS, complex swallowing interventions, PES and cervical strengthening. Future studies could benefit from clear reporting of patient diagnosis and disease severity, the use of more standardised treatment protocols or algorithms and fewer but standardised outcome measures to enable comparison of effects across studies and interventions.

RESUMEN

Biofeedback games and automated functional electrical stimulation (FES) can be used in the treatment of dysphagia. This case study aims to evaluate the effect of the treatment on a 77-year-old man with chronic Wallenberg syndrome and his and the therapist's experiences when using this therapy form. The participant received intensive treatment for nine days with Facial Oral Tract Therapy, biofeedback games and FES. The Penetration Aspiration Scale was scored using Functional Endoscopic Evaluation of Swallowing at baseline and the end of the intervention period. Swallowing-specific parameters were measured daily, and interviews were conducted with the patient and therapist during the intervention period. The patient and therapist both expressed a positive attitude to the ease of use and usefulness of this technology, despite there being no measurable change in the participant's swallowing and eating function and only small improvements in swallowing parameters. The experience from this study was that biofeedback games and FES gave only small improvements in swallowing for this participant but were motivating and easy to use. Further research is needed to investigate the effect of this therapy on other participants with a more robust research design.

RESUMEN

INTRODUCTION: Dysphagia is highly prevalent in patients with acquired brain injury (ABI) and is associated with high morbidity and mortality. However, dysphagia management varies greatly between units and internationally, and there is currently no consensus, standard intervention or treatment. A review mapping the existing literature on dysphagia treatment is needed. In this paper, the protocol for a scoping review to identify and map dysphagia treatment following ABI is outlined. OBJECTIVE: The objective of the scoping review is to systematically map the existing research literature to answer the research question: Which non-surgical, non-pharmacological interventions are used in the treatment of dysphagia in patients with moderate and severe acquired brain injury in the acute and subacute phase? METHODS AND ANALYSIS: The methodological framework for the study is based on methodology by Arksey and O'Malley and methodological advancement by Levac et al. We will search electronic databases in June 2019: MEDLINE (Ovid); Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library); EMBASE (Ovid); CINAHL (EBSCO); PsycINFO; Science Citation Index Expanded on Web of Science; OTseeker; Speechbite and PEDro. The search terms will be limited to patients with moderate to severe ABI and dysphagia. Four review authors will independently conduct an initial screening of title and abstract and subsequent full-text review of included studies. Data will be extracted and summarised in diagrammatic or tabular form (numerical summary), and a descriptive format (narrative summary). The strategy for data synthesis entails qualitative methods to categorise the interventions based on the treatment modality and subgroup diagnosis. ETHICS AND DISSEMINATION: Scoping the existing literature will provide a foundation for further evaluating and developing our dysphagia treatment and inform future studies assessing the effectiveness of treatments. The review is part of an ongoing expansive research into dysphagia. The results will be disseminated through a peer-reviewed publication and conference presentations.

RESUMEN

AIM: The aim of this study was to describe and define the rehabilitation approach: 'Facial Oral Tract Therapy' (F.O.T.T.). METHOD: We defined the content and process of the rehabilitation approach (F.O.T.T.) in a decision-algorithm supported by a manual with supplementary material. The algorithm was developed by a research occupational therapist and an F.O.T.T. senior instructor. We used an inductive approach combining existing knowledge from: F.O.T.T. instructors, therapists trained in using the F.O.T.T. approach, and existing literature. A group of F.O.T.T. instructors and the originator of the treatment approach Mrs. Kay Coombes has given comments to and approved the algorithm. RESULT: The algorithm consist of five flowcharts: 'one assessment' chart guiding the therapist in the examination of the patient and four 'treatment charts', one for each of the four areas of F.O.T.T.: swallowing and eating; oral hygiene; breathing, voice, and speech articulation; facial expression, giving guidance on interventions. The algorithm outlines all important components in the treatment that the therapist should decide to use or not to use in the intervention. The algorithm is supported by a manual with criteria of when to use which components. CONCLUSION: This algorithm is designed to be a practical guideline to therapists using F.O.T.T. in clinical practice and in educational settings. The use of this algorithm may support standardization of F.O.T.T. and thereby promote and maintain the quality in the treatment. This in turn will facilitate research that addresses F.O.T.T. and outcomes.
