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


There are several options for treating mild obstructive sleep apnoea

Many OSA therapies focus on creating space in the airway. 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 Devices work by temporarily moving the jaw forward. CPAP machines pump air pressure into your upper airway.

2. Surgical treatments


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 has multiple causes, including reduced responsiveness of the tongue and upper airway muscles4.

eXciteOSA for sleep apnoea changes this. It trains your tongue to stay in position, letting you sleep soundly.

eXciteOSA for Snoring and Sleep Apnoea is clinical proven

Reduces Apnoea’s

A recent study found a 52% reduction in the AHI and a 50% reduction in the ODI amongst responders – all without a CPAP or MAD3.

Frequently asked questions

Transcutaneous electrical nerve stimulation (TENS) machines stimulates the sensory nerves (the nerves that send signals from the body to the brain) with the purpose of disrupting the pain signal.

Neuromuscular electrical stimulation (NMES) also uses electrical stimulation, but targets the motor nerves (the nerves that send signals from the brain to the body) in order to stimulate the muscles directly.

Sensory and motor nerves fire at different frequencies, which is how TENS and NMES devices are able to impact them differently.

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® targets the tongue to promote endurance of the muscle, thereby reducing airway collapse and snoring during sleep.

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

There are several options for treating sleep apnea.

Manudibular advancement devices (MADs) work by temporarily moving the jaw forward, in order to create more space in the airway.

CPAP delivers air pressure through a mask to open up the airway.

Surgery is usually an option to consider after other treatments have failed. Examples include removal of soft tissues from the airway, or procedures designed to stiffen the airway.

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.

Risk-free trial

* 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 £70 + 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.
