Swallowing Therapy With the Assistance of a Mobile Health Device in Head and Neck Cancer Patients: a Pan-Alberta Study
Dysphagia affects 22% of those over the age of 50, which equates to 250 million people worldwide and 360,000 in Alberta. At high risk are survivors of head and neck cancer (70%). Difficulties with swallowing are not only life threatening and resource-intense, but also socially limiting. To regain swallowing function and avoid or reduce the consequences of dysphagia, patients require regular, intensive therapy over many months to strengthen swallowing muscles and improve swallow coordination. This therapy is often coupled with visual biofeedback that uses surface electromyography (sEMG). Despite evidence that swallowing exercises are effective when provided with an intensive regimen and when coupled with sEMG biofeedback, patients rarely receive it. The primary aim of this work is to determine whether the use of a mobile system equipped with sEMG biofeedback affects adherence to home-based swallowing exercises. The secondary aim of this work is to determine if the exercise program results in improved patient reported outcomes related to dysphagia and nutrition. Our tertiary aim is to determine if previous findings of adherence can be replicated. Sixty adults with oropharyngeal dysphagia secondary to OPSCC treatment will be enrolled in the study. This study will follow a cross over randomized design such that all participants will be provided with both types of treatment: using pen and paper (Treatment Arm A) and using the mobile health system (Treatment Arm B).
