The Daily Mail reports on a tongue muscle trainer.

Poor muscle tone in the tongue is thought to play a key role in sleep apnoea. It means the tongue is more prone to relaxing too much and falling backwards into the airway while a patient sleeps.

The new tongue trainer is a handheld device — at one end is the air-filled bulb, which is roughly the size of a medicine capsule. This bit goes inside the mouth.

At the other end is a device that measures the pressure of the tongue against the bulb.

The patient has to reach a certain target pressure and, once reached, they must hold each position for 30 seconds.

Using the device, patients move their tongue into different positions, shifting the bulb so the tongue works against it.
