Treatment of Dysphagia with Biofeedback and Functional Electrical Stimulation in a Patient with Wallenberg Syndrome: A Prospective Case Report

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.
