The Sleep Position Trainer

A new treatment method for positional sleep apnea


NightBalance’s active sleep position sensor is a new treatment method for positional sleep apnea, developed following research conducted at the Technical University Delft. NightBalance’s Sleep Position Trainer (SPT) is a small, light aid which can be worn around the chest with an ergonomic band. This effectively and comfortably prevents the apnea attacks at night, and helps reduce sleep apnea patients’ (and their partners’) symptoms.

Position therapy as an effective treatment for POSAS

Approximately over half (56%) of all patients with Obstructive Sleep Apnea Syndrome (OSAS) have Positional OSAS (POSAS), where the supine AHI > 2x AHI non-supine. This is especially the case with light or moderate OSAS.

For further information regarding the definition of POSAS please go to Definition of POSAS.

Various research has shown that the reduction of lying supine is an effective treatment for positional sleep apnea. When the sleep position is adjusted, the symptoms and problems of positional sleep apnea reduce. The avoidance of lying supine is referred to as position therapy.


To date there were only poor methods available for position therapy. These methods disturb sleep and don’t appear to be comfortable enough for patients to use them in the long-term.

NightBalance introduces a friendly solution

NightBalance’s Sleep Position Trainer (SPT) is an active sleep position sensor which gradually and comfortably trains patients using gentle vibrations to not sleep on their back.

Because the SPT is small, it is comfortable to wear and the patented technology ensures a friendly yet effective treatment. The medical aid is worn around the chest with an ergonomic strap developed with research conducted at the Delft University of Technology.

The Sleep Position Trainer continuously measures personal sleep behavior and on the basis of this information gives a light vibration at necessary times to encourage change of position. During sleep, the comfortable device reminds your patient, when necessary, not to lie on their backs.

The active sleep position sensor is comfortable to wear and easy to handle, making its long-term use possible. NightBalance has conducted extensive research into what people find important in their sleep, ensuring the device has been created in such a way to make it as comfortable and user-friendly as possible.


Small and ergonomic 
The active sleep position sensor is small, light and comfortable to wear to ensure sleep is relaxing.

Free to turn easily
Your patient can easily change their position (also via their back) without the sensor producing a vibration, as the vibration only commences when the patient remains on their backs.

Falling asleep period 
The active sleep position sensor only starts to work when your patient is actually asleep to allow them to fall asleep on their back if so desired.

A gradual training program
The active sleep position sensor gradually trains your patient to not sleep supine to allow them to get used to doing so.

 Pause mode     
The device can be put in pause mode for 20 minutes when your patient desires to allow them to choose for themselves when they want to lie on their backs.

Personally adjusted
The active sleep position sensor automatically adjusts the intensity of its vibrations depending on the sleep behavior of your patient.

Sleep software displaying the data
The SPT is motivational to use as your patient can see the sensor’s data via their computer, allowing them to follow their sleep behavior – which improves the effectiveness of the treatment. The medical specialist is also able to look at the data with the patient in order to clearly assess a patient’s progress.

Online support
If your patient grants access of their SPT data to NightBalance, we can provide support in the device’s use as well as tips and advice on how to improve their sleep. In addition they will receive feedback on their training progress.

Clinical research of the Sleep Position Trainer

Clinical studies in the Medisch Spectrum Twente and the Sint Lucas Andreas Hospital show that the active sleep position sensor is an effective medical aid for positional sleep apnea with a high compliance rate (Van Maanen et al., 2013). The medical specialists involved with the studies have identified the NightBalance SPT as a readily accepted treatment for their patients with light and moderate POSAS. In total there are currently 18 hospitals in the Netherlands working on further research.

The treatment of POSAS makes for a better night’s sleep and a more relaxed feeling during the day for people with sleep apnea and their partners.

Reviewing your patient’s data

The Sleep Position Trainer saves all actions that occur during the night into its internal memory. Your patient is able to review this data to follow their sleep behavior both via the device itself and by connecting the device to a computer. Provided that your patient grants you access, as the treatment specialist you are able to review and analyze your patient’s data.


Patient’s time spent lying supine


Overview of all your patients

Patients can review the results of their therapy themselves. To do so your patient connects the Sleep Position Trainer to a computer and uploads the data from the sensor using the SPT software. Aided by the web application your patient is able to review the percentage of the night they spent lying on their back. Your patient is also able to review which sleep positions they slept in and how often the sensor produced vibrations on a nightly basis. This data will be clearly displayed in various graphics.

As the specialist you have access to see the sleep data of your patient, provided that they grant you access to this. Your patients are all displayed in one summary table and you will see a notice when one of your patients requires special attention and guidance, for example if your patient has not worn their Sleep Position Trainer for several nights. You are able to review all the sleep data since the first day your patient slept using their SPT.

The reviewing and analysis of the sensor’s data will provide you with a better insight into the treatment of your patient.
