Identification and Dynamics of the Rheological Properties of the Human Axial System by the Transfer Vibration through Spine (tvs) Method

The human musculoskeletal system interacts with other objects in the environment. The hypo or/and hyperkinetic character of interactions causes changes of the rheological properties in connective tissue. This paper shows case studies that indicate the advantages of using TVS method for the identification and classification of the human axial system changes in different physical activities. The investigated activities and their influence on the axial system were mainly monotonous vibration loading while driving, extreme training loading among rhythmic gymnasts and ageing. The TVS method is based on the fact that the speed of mechanical wave and the quantity of mechanical energy transmitted through connective tissue depend on the characteristics of passing tissues. The difference between the input and output accelerations measured on the spinous processes reflects the tissue characteristics. The TVS method is very suitable for all the classification and regulation of extreme and normal physical activities, ageing prevention, quantification of the human axial system among particular groups of people and also for the diagnosis of surgical and therapeutic interventions.
