Based on the scientific structure of the studies proposed by the FIMM Academy the Marsman Foundation decided in a paper to develop a scientific research program to investigate the reliability of the basic lateralisation tests which are used by the practitioner to diagnose asymmetric mobility in the individual (VAN WYLICK). Second to this step mobility tests are examined and related to lateralization tests. At the end of this 5 year program a RCT will be developed in the direction of treatment technics.
