Overview
The main objectives of the study are (1) to investigate if sleep positional therapy, using the LEFT smartwatch app reduces nocturnal gastroesophageal reflux symptoms in patients with gastroesophageal reflux disease symptomatology at night and (2) stimulates patients to avoid sleeping in the right lateral sleep position.
Description
Gastroesophageal reflux disease (GERD) is one of the most common gastro-intestinal disorders and approximately 50-80% of the GERD patients experience nocturnal gastroesophageal reflux symptoms. Symptoms at night have a negative impact on sleep quality, daytime functioning and quality of life. When sleeping in left lateral decubitus position, the stomach is positioned below the esophagus, resulting in less reflux compared to sleeping in right lateral decubitus position. Sleep positional therapy, using an electronic wearable device which gently vibrates in an annoying way when turning in the sleep to the disadvantageous right lateral decubitus position, stimulates subjects to avoid sleeping in the right lateral decubitus position and effectively alleviates nocturnal gastroesophageal reflux symptoms. This prospective single center interventional pilot study will aim to (1) investigate if sleep positional therapy, using the LEFT smartwatch app reduces nocturnal gastroesophageal reflux symptoms in patients with GERD symptomatology at night and (2) stimulates patients to avoid sleeping in the right lateral sleep position.
