The use of electronic in measurement of Rachi's curves was started in 1974 by the construction of "Wielki's Electronic Spherosomatograph" presented 21 act. 1978 in Marseille (France) at the "Troisieme Reunion Scientifigue de Medecine du Sport des Pays Latin". During research for a "Main Type" and for mathematical model of the spine it was established that recording of the rachi's curves must be done from upper point "A" C7 to lower point "B" L5+/ - 8% of the measured length and tha t the dorsal and lumbar curves could be related to the sizes of their radius. The method was named "Radius Method with Intersection Point". In applying 10 Indexes on a student "Normative Group" a "Normative Typology Type A -Normal, Type B -Lordotic, Type C -Kyphotic for each sex was elaborated allowing for evaluation of sports groups. These evaluation showed special characteristics in the change of direction of the curves. When comparing with the Normative Typology, deviation and deformatinn of the rachi's curve exist by subjects with over charge of Rachi's or with unilateral activities. Functional adaptation can be accepted and and is normal but deformation and deviation caused by over charge in activities especially with youth or even infants, and top athletes are disputable. In applying on top sportsmen the method Improved Radius Method with Intersection Point it was discovered that the Rachi's curve if it allows for classification does behave singularly depending on "psycho-motorsports activities". An individual's spherosomatogram is thus indispensable. Of the 10 indexes which allow to establish a "Normative Typology", only 2 are sufficient in the study of an individual spherosomatogram and to diagnose the weakness evolution of the Rachi's Curve: 1. Dorso-Lumbar Index (DU 1) - relation between the lengths of the curves. 2. Curve Relatif Index (CRI 2) - relation between the heights of the curves. The changes in these indices are closely dependant. Further indices are necessary when establishing programs to stop bad evolution and prepare preventive corrective activities: 3. Dorsal Top Index (DTI 5) -position of the top of the dorsal curve. 4. Lumbar Top Index (LTI 8)- position of the top of the lumbar curve It is indispensable to understand the functional changes in the Rachi's curve as part of the process of biological development and change due to "psychomotor- sport-activities". Spherosomatography and the "Improved Radius Method with Intersection Point" are a non-invasive method that can be used again and again without damage and where the results are visually and immediately registered which helps corrective action.
