Rest and avoiding re-injury or re-aggravation are often the sum of what is offered for treatment of concussions. This is a great beginning, but incomplete as a stand alone treatment process.
There are some key areas that should be assessed and treated if necessary.
-Fluid drainage from head, including venous and cerebral spinal fluid.
-Asymmetric neural tension
-Asymmetric bone tension
-Asymmetric membrane tension (meninges).
- Cervical alignment, though high velocity manipulation often re-aggravates.
Each of these contribute to pressures inside the skull, these very pressures inhibit optimal healing.
For a simple analogy, consider someone that has lost 50% of arm flexion. They can do biceps curls as much as they like, but they’ll only get stronger within the range of their existing movement. By increasing arm flexion (through manual therapy) a greater portion of the muscle will be conditioned through exercise.
The brain has similar limitations, if there is a physical barrier. For instance, diminished blood flow, swelling or inflammation, scarring, minor displacement of tissues, etc.
Then exercising and retraining the brain is literally going to be met with resistance.
Restoring good blood flow and balancing pressures inside the head are often primary objectives. All tissues need oxygen and nutrients to heal, but this is heightened in the brain. For instance the brain constitutes roughly 2% of the body by weight, but receives 20% of the blood flow and 20% of the oxygen. If vascular flow is affected, its restoration is imperative. To intentionally challenge this system is like having a clogged sink and attempting to unclog it by turning the hot and cold water on at the same time.
The heads internal pressures are also effected by, the cerebral spinal fluids ability to drain and circulate. An example of how vascular pressures are effected by cerebral spinal fluid flow and how cerebral spinal fluid pressures are effected by the vascular pressures would be; to place two non-inflated balloons in a jar, begin inflating one, we can see that the more we inflate the first balloon, the greater the effect it has on the remaining space for inflation of the second balloon. The point here is, there is a relationship between these two systems, and each has a direct influence on the function of the brain.
Manual therapy is very effective in treating of concussions and minor traumatic brain injuries. Because there are specific techniques to improve the function of the nervous system, vascular system, biomechanics, etc.
Manual therapy works by:
Understanding anatomy and working with the various relationships that arise as a result of trauma.
Respecting the body where it is and working with it, rather than imposing treatment with a willful and non-receptive attitude.
This is critical to gaining deeper access to the body, many styles of treatment elicit defensive posturing. Defensive posturing and access to the body’s deeper structures run counter to one another.
