*7.1.2.1 Study: Esophageal dysphagia and reflux symptoms before and after oral IQoro training*

#### **Study type**

Peerreviewed, Prpospective, cohort pre and post-study [14].

43 patients who had esophageal dysphagia for a median of 3 years (range: 1–15 years) were recruited to this study. All displayed the symptoms of a Hiatal hernia, but only 21 had had their condition confirmed by examination. All had been prescribed Proton Pump Inhibitor (PPI) medication for more than 1 year without any effect, all medication ceased at the start of IQoro treatment.

*(A) Sliding hiatal hernia. The upper part of the stomach and the LES has slid up through the hiatal canal. This allows gastroesophageal reflux and also causes difficulties with opening the PES at the top of the esophagus. (B) Normal anatomy. The neck of the stomach is correctly held below the diaphragm promoting normal LES function and preventing reflux.*
