**1. Introduction**

Dysphagia is a widely prevalent phenomenon that brings the risk of other conditions like malnutrition, pneumonia, and even the necessity for non-oral feeding solutions [1–3]. It always leads to reduced quality of life, and can even be fatal [4].

#### **1.1 Few real solutions**

The ways that patients with dysphagia are cared for fall into two broad categories, of which the first is by far the most common. Patients are often provided with compensatory care, [5, 6] which allows them to live with the disabilities that dysphagia brings. These therapies may include modified often puréed solid foods

that are easier to swallow, and thickened drinks that can be swallowed more safely with less risk of aspiration. Instruction on posture, eating habits, oral hygiene and more, are also common.

The second category of care is rehabilitation treatment [7–11] to address the causes of the dysphagia. In general they focus on increasing muscle strength in the affected organs.
