This is a functional rehabilitation method that does not require any active participation from the patient.
It was theorized as anoetic functional rehabilitation by Doctor Patrick Fellus, an ODF specialist at the Robert Debré Hospital in Paris, in 2011.
The therapeutic goal is to automate new practices by inhibiting dysfunctional circuits and establishing a protocol based on current neuroscientific data.
The reference work on the subject was published in 2020 by Doctor Fellus:“Neuroscience and Swallowing Rehabilitation: Froggymouth - An Anoetic Approach"

Chewing, swallowing, speaking, and breathing are praxes that interact and influence each other at all times. Dysfunction in any one of these can create an imbalance among all the praxes of the orofacial sphere.
 
On the other hand, automated reeducation for swallowing harmonizes the entire orofacial sphere through a chain reaction that begins with the elevation of the styloglossus muscle.
 
 Wearing Froggymouth initially forces secondary swallowing until it becomes automatic.
 
 Once this praxis becomes automatic, the tongue is raised against the palate every time you swallow.
 
 The notion of comfort determines the tongue’s position between swallows.
 
 Consequently, the tongue will adopt a raised position at rest due to repeated elevation during swallowing.
 
​"The notion of comfort is the priority of the new program: the most effective solution is chosen and then consolidated for further use." P.M. Lledo,

Dr. Eric Kandel, awarded the Nobel Prize in Medicine in 2000 for his groundbreaking work, provides valuable insights into neuroscience concerning memory and its connection with emotions.
 
Emotional Response to Froggymouth The inhibition of atypical swallowing leads to a critical response: the necessity to swallow, as directed by the brainstem, combined with the inability to use primary swallowing, results in an emotional shock. This emotional shock acts as a catalyst for engramming the new function into long-term memory. Following this, practitioners should focus on automating the swallowing function.

"An emotional event such as a car accident or a happy occasion like your wedding creates such a strong memory that you'll remember every detail even after 5 or 10 years without having to replay the scene." Dr. P. Fellus.

For adults, the concept applies just as much and in the same way. Like any learning process, the duration of the treatment may be slightly extended.

The television plays a significant role in maintaining the gaze, ensuring a horizontal lingual plane during swallowing. Keeping the lingual plane horizontal is crucial because a bowed head can lead to drooling, which delays the swallowing signal from the brainstem.
 
Moreover, for many patients, watching television is a pleasurable activity. This enjoyment activates the reward circuits managed by the limbic system, promoting the automation of the newly engrammed circuit.

Clinical studies have shown significant results within 10 weeks of treatment.
 
However, the duration can vary from one patient to another. Typically, the automated correction of tongue position with Froggymouth lasts between 2 to 6 months.
 
This treatment duration is indicative and should not dictate the end of treatment.
 
The conclusion of treatment with Froggymouth is determined by the practitioner when the automated correction of the tongue position has been achieved.
