[Role of postural and vicarious muscular overloading in the formation of lumbo-ischialgic syndromes].

On the basis of neuro-orthopedical and tensoalgimetrical studies of 527 patients with sacral ostheochondrosis the authors elaborated a scheme of the distribution of overloading on the muscles of the legs and respective neurodystrophical and algic phenomena. These overloadings were expressed in fixed lordosis, kyphosis or skoliosis due to which there was a redestribution of these overloadings between the antagonists of legs in the sagittal and frontal plane. The overloadings occurred vicariously in some muscles while the others were in a paretic condition.
