Retrain and maintain – What to expect from your therapy

Phase 1


The goal over your first 6 weeks is to retrain your tongue. By week 6 you should be well on your way to a better quality of sleep1-3.

Phase 2


With a retrained tongue, it’s time to maintain the hard-earned benefits. Keep using the device at least a couple of times a week to maintain better sleep.

I like the simplicity of the design and ease of use, and have also had very quick and helpful replies in the case when I needed some customer support.

Kaen Morelli

The chat feature worked very well and they were very responsive to my questions. I think the device has helped me get more quality sleep and I hope to see even more improvements during the maintenance phase!


The customer service team is top notch, is super responsive to concerns, and always does what it can to help. Highly recommend trying it out.

* 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.
