**Study type**

Peer reviewed, Prospective, Cohort pre- and post- study.

**Aim**

To examine whether training with an IQoro Neuromuscular Training (IQNT) improves oesophageal dysphagia and reflux symptoms.

#### **Patients**

43 patients (F = 22, M = 21) median age 57 years (range 22–85) with oesophageal dysphagia of a non-stenotic nature for a median period of 3 years (range: 1– 15 years), of which:


All patients had been using PPI medication for more than one year. **Methods**

IQoro training (**Figure 3** A, B; Video 1), 3 x 10 seconds three times a day, totally 90 seconds per day, for a duration of 6 months. Outcome measurements were made at two time points: before training and at end of training.

#### **Outcome measurements**

Patients (*n* = 12), median age 53 years (range 22–68 years) with hiatal hernia were measured using:

	- the UES (normal restin pressure <sup>&</sup>gt; 30 mmHg, **Table 1**).
	- the diaphragmatic pressure in the hiatus canal (normal resting pressure 10– 35 mm HG, **Table 1**).

All patients were measured using:

	- Visual Analogue Scale (VAS 0–100: 0 = normal, 100 = total inability) [22],.
