Structure dictates function: what it means on the table

How a joint is shaped, positioned and supported governs what it can do. That is the whole principle. It sounds obvious, and in the abstract it is. The work is in what it changes about the order of care.

Load follows the path that is available

The body is good at finishing the task. If one segment of the spine has stopped rotating, the rotation a golf swing needs still happens, taken from the segments above and below. If a big toe no longer extends, the runner still pushes off, through the outside of the foot, the knee or the hip. Nothing fails right away. The movement still gets done; it just gets done by structures that were not built to carry that share.

Training strengthens whatever pattern is being used. That is why we say: load poor structure and you train the compensation. More strength work on top of a joint that is not moving well tends to make the workaround more efficient, not to remove it.

What it looks like during a visit

The assessment looks at the region where you feel pain, and also at the regions that feed it: segment by segment, joint by joint, along the chain. The literature calls this regional interdependence: problems in one region can contribute to symptoms in another, some distance away (Sueki et al., 2013). We are looking for where motion has gone missing, where tissue has lost its glide, and where the body has started borrowing from somewhere else.

Treatment is then specific to what we found: joint work, soft tissue and fascial techniques, and input to the sensory system that tells the brain where the body is. The aim is to restore motion and create space.

Then we reassess. How the body responds to treatment tells us whether we're on the right track, and shapes what comes next. When a region doesn't respond the way we expected, we reconsider rather than repeat the same thing. That feedback matters more than any theory behind the technique.

Then it has to be held

A joint that moves better on the table has only been given the option. Whether the body uses it depends on what happens next. That is why care runs in order: the table, then the floor, then the field. Corrective exercise and ELDOA™ teach the body to hold the new position under control, and strength and sport preparation load it once it can tolerate the load. Skip the middle step and the old pattern usually returns, because it is the one the nervous system knows best.

What the principle does not claim

It does not mean that every asymmetry is a problem. Nobody is symmetrical, and plenty of people with uneven shoulders or a flat foot move and compete without trouble. It does not mean that an image explains your pain: in a review of more than 3,000 people with no back pain, disc degeneration showed up on imaging in about a third of 20-year-olds and in nearly all 80-year-olds (Brinjikji et al., 2015). Findings like these have to be read against how you move and what you feel.

It also does not mean that hands-on treatment simply pushes things back into place. The research on manual therapy points to a large role for the nervous system: the mechanical input starts a chain of responses in the nerves, spinal cord and brain, and those responses likely account for much of what changes (Bialosky et al., 2009). That fits how we think about treatment, as precise input to the nervous system, rather than as repositioning.

And it does not mean every problem is structural. Sleep, stress, training load and recovery all shape how tissue adapts. Structure is where we start, because it is what we can assess and retrain. We judge the work by function: what moves, loads and holds afterwards.
