What is Dystonia?

Medical academic and clinical neurology defines Dystonia as a movement disorder in which a person’s muscles contract uncontrollably.

The contraction causes the affected body part to twist involuntarily, resulting in repetitive movements or abnormal postures.

Dystonia can affect one muscle, a muscle group, or the entire body.

Dystonia affects about 1% of the population.

What Are the Symptoms of Dystonia?

Symptoms of dystonia can range from very mild to severe. Dystonia can affect different body parts, and often the symptoms of dystonia progress through stages. Some early symptoms include:

A “dragging leg”
Cramping of the foot
Involuntary pulling of the neck
Uncontrollable blinking
Speech difficulties

Stress or fatigue may bring on the symptoms or cause them to worsen.

People with dystonia often complain of pain and exhaustion because of the constant muscle contractions.

What came first? The chicken or the egg?

Mainstream academic Neurology defines Dystonia as a neurological disorder with physical movement consequences.

In reality, Dystonia is a physical injury that has neurological consequences.

It is an impairment of the ability of the neck to support the skull.

It is similar to triple broken ligaments in the knee…. except the injury is at the level of the upper cervical and lower cranial areas (TMJ, dental occlusion and sphenoid bone).

Dystonia sits between Traumatology, Dentistry, TMD, Orthopedics and Neurology.

It is a physical injury of the upper cervical, lower cranial area.

This bio-mechanic approach has been around for decades with proven results. It is not mainstream because of the way medical academia organizes research and teaching in separate systems.

And it is not mainstream because there is no money from Big Pharma to fund bio-mechanic clinical studies and research.

The protocol we developed does not invent anything new. In the Resources section of this blog you can find 100 downloadable peer reviewed academic research papers, case studies and FDA approved clinical trials that deal with the biomechanics of neurological movement disorders.

The Bio-Mechanical Impairments of Dystonic Patients

It is extremely important to point out that the medical definition of «Dystonia» does not define a specific disease.

Dystonia means «dysfunctional muscle tone». It is a description of a very extensive range of symptoms, disfunctions, injuries and deaseases that may coexist and might be unrelated.

Patients who have been diagnosed with Dystonia by a neurologist usually present some or all of the following bio-mechanical symptoms:

– Cranial collapse and derangement



Collapse and derangement of cranial bones results in the axis of the plane of dental occlusion being out of alignment with the axis of the skull and the spine


Postural collapse and lateral-frontal sinking skull


Subluxation and misalignment of upper cervical vertebrae

Torsion of the spine, postural collapse, scoliosis, neurological movement disorders (dystonia, Tourette, Parkinson, blepharism, etc.) happen when ONE CONDYLAR DISK IS ANTERIORLY DISPLACED and the OTHER IS POSTERIORLY DISPLACED.

 How to Explain Dystonia

One common problem of people living with Dystonia is being able to explain its neurogical symptoms to other people.

Dystonia is a rare desease-condition. Most people have never heard of it and do not understand it. It is common, even for uninformed medical professionals, to believe that it is a psychological issue.

I find that the best way to explain it is through a short introduction and a video.

It is a movement disorder with neurological symptoms which make muscles go into spasm so that the chin is pulled and tilted, the head turns sideways and the spine twists (or whatever your symptoms are). 

The body has a twisted perception of alignement, verticality and the horizon and constantly pulls the spine to a twisted, unnatural, misaligned position.

It is related to Parkinson’s and Tourette.  

A simple explanation is often best, and a video reference speaks more than a thousand words. This video produced by the Oprah program can help.
