The system of registration and recording of the quasiperiodic processes in the human tissues is used. The research is based on detecting, measuring and recording the changes in different tissues reacting on variable degrees of occlusion. This enables us to analyze various changes within the liquid systems as well as changes in micro-or macro-mobility of the tissues. Presented are experimental data of the wave processes occurring in the human tissues with different constant levels of occlusion used. The spectral characteristics of the periodic volumetric changes in the tissues serve for the evaluation of the body's functional state. This model can be used as a means of verifi cation for the diagnostic and manipulative purposes in Osteopathy.
