Along with our physical solutions we believe we’ve developed a general theory of how the human body and brain interconnect, and how muscular imbalances in the neck lead to mental disabilities. This also implies that if the neck musculature can be brought back into equilibrium, some mental health issues and disabilities can be genuinely cured.


It also provides a functional explanation that explains why many ‘alternative therapies’ such as acupuncture may work and also why other practices such as meditation may have direct physiological benefits. However after delving deeper, it also explains why these therapies won’t necessarily cure all conditions. 


The diagram and explanation below will summarise the theory (note this is not a full explanation or justification, just a quick overview).

How it works:

Muscles - can develop imbalances. According to our theory, there’s a general sense of muscular balance that’s required to keep the body and by extension, the brain, properly functional. This balance can be measured by developing measures of ‘relative muscular strength’ or ‘relative muscular activation’, same thing just a different way of thinking about it. The deep neck flexors such as Longus Colli and Capitis and deep neck extensors such as Semispinalis Cervicis and Capitis connect to the upper cervical spine and occipital bone and are therefore the most important muscles that must remain in balance.


Bones - due to muscular imbalances, bones can move outside a suitable ‘angle of articulation’ range. The single most important joint and therefore angle of articulation measurement is the one at the spheno-basilar junction. A lack of ‘smooth’ articulation at this joint represents problems in the rest of the body as well as causing them.


Nerves - when bones don’t articulate properly they cause compression and stretching of nerves. Directly this causes pain but it also changes the messaging being passed by the nerves. This can lead to further muscular imbalances as well as a wide range of issues when it happens to cranial nerves.


Cerebrospinal Fluid - this is where things start to get interesting. Muscular balance changes lead to cranial articulation changes, which in turn change the shape of the space within which cerebrospinal fluid is flowing. Our hypothesis is that this in turn changes cerebrospinal fluid flow from ‘laminar flow’ to ‘turbulent flow’. This does two things, firstly it changes the pressure on regions of the brain that the cerebrospinal fluid is contacting, secondly the turbulent flow may be constantly changing and hence the pressure on the brain is not only different to some optimal amount, but also constantly changing due to the turbulence.


Brain Regions - regions of the brain that are in contact with cerebrospinal fluid have differing forces applied to them. Since the brain is non-rigid, these 

changes in force also affect regions of the brain that are more internally located, but of course to a lesser degree the further into the brain we go. The change in forces on the brain depends on the change in cranial deformation (which depends on the degree of muscular imbalance). However since the flow is turbulent, ‘chaotic dynamics’ applies, which means we can’t estimate with confidence the degree of change on the brain by simply knowing the cranial change (for the same reason we can’t confidently predict the weather for more than a few days).

Note: the concept below is a complex idea which requires a lot of elaboration to be properly understood and further research to be verified. If you have a specific interest in our theory of how synaptic connections are changed by muscle -> bone -> CF flow imbalances please send us a message.

Synaptic Connections - as the forces on the brain regions change, this leads to disruptions in the synaptic connections between neurons. Due to the ‘chaotic’ nature of the disruption, the connections cannot ‘stabilise’. In the case of artificial neural networks, layers in the network are connected by activation functions, which essentially pass numbers from neuron to neuron. If we assume the amount of chemical neurotransmitter (dopamine, potassium etc.) represents the output of an activation function (since it probably does) then it’s obvious that disrupting the physical synaptic connection will have some effect on the uptake of chemical neurotransmitter by the receiving neuron, and this change is almost always likely to be a reduced amount. In turn this is likely to change the resulting computation of the receiving neuron (due to a changed input) and then both the changed computation along with another disrupted synaptic connection causes further changes along the biological neural network.


The net result is that seemingly insignificant changes in muscles that attach to the cranium can change a person’s personality, thoughts, opinions, memories and ideas.
