eXciteOSA for Sleep apnoea allows you to sleep without wearing a mask or MAD


There are 4 common types of clinically proven treatments for Mild OSA

Three of them open up or create space in the airway. The fourth, NMES, does something unique.

1. Nighttime treatments

Uncomfortable. Difficult to tolerate

eXciteOSA for Sleep Apnoea is an alternative to CPAP and MAD

Mandibular (jaw) Advancement Device works by temporarily moving the jaw forward. CPAP machine pumps air at pressure into your upper airway.

2. Surgical treatments

Invasive. Variable Results3

Radioablation is an alterative treatment to eXciteOSA for snoring and for sleep Apnoea

Surgery is usually an option after other treatments have failed. Examples include tissue or tonsil removal.

3. Daytime NMES therapy

Simple, effective & painless

eXciteOSA for snoring, exciteOSA for Sleep Apnoea delivers NMES to the tongue.

NMES physiologically retrains the upper airway and tongue, to stay in its natural position while you sleep.


eXciteOSA For Sleep Apnoea – A Daytime Therapy

Neuromuscular electrical stimulation (NMES) with eXciteOSA®

NMES safely activates nerves and trains muscles. NMES is a familiar and well-established technique in medicine and athletics.

Sleep apnoea often has multiple causes. A common cause is the tongue and the upper airway muscles. Aging, diet, and other contributors can lead to neuromuscular degeneration in these areas resulting in OSA.

eXciteOSA for sleep apnoea changes this. It trains your tongue and upper airway muscles to have the stamina to stay in position all night long, letting you sleep soundly.

Oral Dental Devices (MRD/MAD) require you to wear something at night and effectively splint your airway open by moving the tongue forward and out the way. Surgery can also be an option. eXciteOSA for Sleep Apnoea is a daytime therapy.

NMES is different

eXciteOSA for Snoring and Sleep Apnoea is daytime therapy for sleep apnoea and snoring

Convenient daytime therapy

Comfortable and painless leaving you with nothing to wear at night.

eXciteOSA for Snoring and Sleep Apnoea is clinical proven

Reduces Apnoea’s

Published studies show a reduction of 52% in AHI and 45% in ODI – All without a CPAP or MRD.

Frequently asked questions

Transcutaneous Electrical Nerve Stimulation (TENS) machines stimulate the nerves exclusively for the purpose of relieving pain.

Neuromuscular electrical stimulation (NMES) produces regular contractions of muscles and produces changes in blood flow, activated nerves, and muscle [fibers], which may increase the health of the target muscle and surrounding soft tissues. Definition from the Handbook of Clinical Neurology, 2012

eXciteOSA® is a user-controllable neuromuscular electrical stimulator (NMES) that delivers a mild electrical current with defined frequencies to stimulate and improve muscle function in the mouth and tongue.

Unlike traditional sleep apnoea treatments, eXciteOSA® strengthens tongue and throat muscle tone, to prevent excessive muscle relaxation during sleep, reducing airway collapse and therefore reducing OSA.

A daytime therapy with no night-time wearable necessary for a better night’s sleep.

There are 4 common types of clinically proven treatments for snoring, each with the goal of opening or freeing your airway.

Mandibular (jaw) Advancement Device works by temporarily moving the jaw forward and the tongue goes with it, creating space at the back of your throat to help you breathe. CPAP on the other hand delivers positive pressure to open up your airway.

Surgery is usually an option after other treatments have failed. Examples include tissue or tonsil removal, again, with the intention of creating space. Alternatively, there are now implantable devices that, when switched on, apply gentle stimulation to key airway muscles during sleep, allowing you to breathe normally. This treatment is normally reserved for severe patients who have refused or do not tolerate CPAP.

NMES physiologically retrains the upper airway and tongue to maintain the tongue’s natural position while you sleep, effectively helping your body help itself. eXciteOSA For Sleep Apnoea is the only device that delivers NMES. You can also refer to the chart above to better illustrate the main difference.

* Terms and Conditions of the Sleep Guarantee: You must start using the exciteOSA For Sleep Apnoea within 1 x calendar week of receiving your eXciteOSA. For optimal results, you should use it every day for 6 weeks. However, we know that we are all only human and people forget things – so we ask that you use it for a total of 6 weeks (a total of 42 days) within an 8 week period (56 days). A session is equivalent to 20 minutes. In addition, it is recommended that you increase the therapy intensity gradually over the treatment period to ensure that you give the treatment every chance of being effective. Please note that once the initial therapy is finished and to maintain the treatment you need to use the device at least twice a week forever.

The mouthpiece is a precision piece of engineering responsible for delivering neuromuscular electrical stimulation targeted primarily at the tongue. It needs to be replaced every 3 months and therefore will not be refunded as part of the ‘try before you buy offer’. We will deduct £54 + VAT from the final refund amount. Signifier will send you a return label for the device to be returned. Please contact Signifier Medical to arrange this.
