NightBalance, a spin-off of the Technical University Delft, developed the Sleep Position Trainer (SPT) to prevent positional sleep apnea. Sleep apnea causes many problems, including daytime drowsiness, lack of concentration, irritability, heavy snoring and as a result reduced quality of life. NightBalance found the solution: the SPT.
The innovation is a smart way to gently train patients to sleep on their side instead of their back. The SPT gives a light vibration that nudges the patient to change their sleep position. This only occurs during the light sleep stage, so that the natural sleep pattern of the patient is not affected. Patients are able to move freely during the night. Other features include a system that enables patients to gradually get used to sleeping in new positions and avoid sleep disruption.
