The foundations of this method were laid by Jaap Marsman, physical therapist, from Enschede (Holland).
In the seventies Marsman, pupil of Van der Bijl, developed a highly simplified empirical concept to evaluate the specific mobility of the spine.
This was called "Model"-thinking.
Model-thinking implies an overall analysis of posture and motion, based on three-dimensional asymmetry in one individual.
This asymmetry is related to the patient's posture and motion, which he adjusts owing to pain and/or
changes in mobility.

The power of this concept lies in the simple though original mechanical approach, a three-dimensional examination, the use of a type-model, the integration of conventional examination techniques, a concept to reach a working-diagnosis, practical three-dimensional (mostly gentle) motion techniques, use of earlier obtained rational (physical therapeutical abilities.
Above all the method offers a different insight into motion of the individual. It is easy to learn and can soon be applied.

The method should be seen as one vision on posture and motion in the daily practice. This thinking-pattern can be used in fields of diagnosis, exercising therapy, massage, manual therapy as an analysis of posture and motion in work and (top)sports.
