If f 2 has been calculated from (7) then can be calculated f 1 , f 3 from (4), (5). The ratio of dimension l 1 , l 2 , a, b 1 , b 2 , c were estimated according to measurements at applied braces: l 2 = 2l 1, a = b 1 = 0.2 l 1, c = b 2 = 0.2 l 1 (8) The loading coefficients are after setting (8) to (4), (5), (7) The first problem is to calculated spine curve correction as an effect of telescope force F. The spine is considered stiff at vertebra parts and elastic with moment of inertia I and module of elasticity E at inter-vertebrae parts. The values EI must be calculated for observed patient (the values EI can be determined for one patient and transformed by scale for the cured patient). The spine load from brace is partly parabolic and the parts between the parabolic loads is unloaded (see Fig. 1). The parabolic load is (see Fig. 2) where ξ is local coordinate from the load origin and f a is load value at the center. The bending moment is calculated from differential equation The spine correction (horizontal displacement as a brace effect) w and turning spine axis ϕ is at vertebra part given by where w 0 , ϕ 0 are values at vertebra origin and ζ is local coordinate. The values w and ϕ at inter-vertebrae part are given by differential equations EI ’ = -M, w’ = The values w and ϕ are calculated step by step from spine origin at the first with initial condition w(0) = (0) = 0 356 The 9 th Prague-Sydney-Lublin Symposium
The problem can be solved by Newton’s iteration method with numerical derivations. The problem of solving differential equations and minimum of quadratic error is shown at [1]. The article [1] searches the brace with regulated pushing on patient trunk consisting from 3 parts with 2 couples of joints and telescopes. The new types of brace with regulated pushing on patient trunk is moor effective the previous types. Bought problems were interpreted on computer. The program can be used for computer aid design. It calculated optimal telescope forces for measured patient data on X-ray and patient positive plaster form. Bibliography Figure 3. Patient with brace. 1. ČULÍK, J., MAŘÍK, I., ČERNÝ, P. (in press) Treatment of Children Scoliosis by Corrective Brace with Regulated Force Effect. Journal of Musculoskeletal & Neuronal Interaction. ISMNI Greece. If the final value on the spinal end is w end = w(l), the new correct initial value ϕ 0 is 0 = -w end/l where l is spine length. The second problem is to determine optimal value of telescope force F. The optimal spine correction is if the quadratic error of correction values w i and the spine curve points y i measured at X-ray is minimal ambul_centrum@volny.cz 357
