What is neurodynamics?
Neurodynamics refers to the mechanical relationship between neural structures and their surrounding tissues. Nerves must glide freely within fascial sheaths; when this movement is restricted (adhesions, tension), signal transmission can be compromised — leading to pain, numbness, or "sensory amnesia."
Key Principles
- •Neural mobility — nerves slide and stretch relative to fascia, muscles, and bones
- •Tensioners — positions that create mechanical load on nerve pathways (e.g., slump test, straight leg raise)
- •Sliders — movements that promote gliding without excessive stretch
- •Double-crush — multiple sites of compression can compound dysfunction
Why does Neurodynamics matter?
Neurodynamics matters because the brain is not a static wiring diagram; its function depends on how activity changes from moment to moment. Studying these patterns helps explain how the brain switches between states such as rest, focus, and sleep.
This view is useful for understanding rhythms, transitions, and stability in brain activity. It also offers a framework for conditions where activity patterns break down, such as seizures, in which normal dynamics give way to abnormal, overly synchronized firing.
How is Neurodynamics measured?
Neurodynamics is measured by recording brain activity over time and analyzing how it changes. EEG and MEG are the most common tools because they capture activity on the scale of milliseconds, fast enough to follow brain rhythms and rapid transitions.
Researchers then apply mathematical methods to the recordings. These include frequency analysis to track oscillations, measures of synchrony between regions, and models from dynamical systems theory that describe stable states and shifts between them. Recordings from implanted electrodes, usually done only for medical reasons such as epilepsy surgery planning, give more precise local detail. Interpreting these models requires care, since many different mechanisms can produce similar-looking patterns in the data.
In ONDA Life
Part 14 (I Channel) targets neurodynamics to eliminate "congestions" — muscular, vascular, and neural blocks — for the free distribution of energy and signals. Optimizing nerve sliding prevents signal compression and supports high conductivity.
