Does it come from the foot or the jaw? Ascending & descending chains

For years there has been debate about where postural complaints come from: from below — or from above. Both models have merit. The question gets interesting when you think it through.

Our body is connected via muscle and fascia chains. If tension changes at one point, it can become noticeable somewhere quite different. Two explanatory models face each other here.

Two viewpoints

Ascending chain

The origin lies below — in the position and length of feet and legs. This acts upwards to the jaw.

Descending chain

The origin lies above — in the jaw position. It influences posture and body tension downwards.

The orthopaedic view — thought through

From an orthopaedic view it is often said: the legs are not the same length, the feet don’t stand correctly — and this affects the bite. Understandable. But conversely this would mean: the jaw always grows symmetrically and straight, and thumb-sucking, tooth loss, tooth migration or orthodontic procedures would have no influence on body statics. This is exactly where it gets difficult.

If it were only the feet: why do so many people have complaints right after waking in the morning? They don’t sleep standing up.

Studies regularly show that the bite influences body statics. Unfortunately these approaches are often not pursued and rarely consistently translated into treatment concepts.

Our view: take both directions seriously

It is not an either-or. Ascending and descending chains can influence and reinforce each other. That is exactly why we never look at the jaw in isolation, but in interplay with posture and body tension — and work with physiotherapy and osteopathy when needed.
