Abstract

The author has planned this research utilizing two models theoretically supported through biomechanical and mathematical laws, as they were formulated by means of data selected from paleoanthropological literature and his own clinic-instrumental case studies, on patients who were stimulated through manual pressure. The hypothesis was: is the paradoxical advantage reasonable for attaining and validating the mode of habitual, vertically aligned posture among evolutionary human-like beings through a vertical load upon their spine, as it is possible clinically in the course of rehabilitation? For assessing this argument two models, one biomechanical and the other mathematical were made up. They test the above mentioned load, as it reaches the clinically ascertained threshold value for triggering a firm gravitational alignment which is in agreement with bipedal gait. The suitability of the biomechanical model derives from reliability of the successively advancing levels of evolution (Anagenesis) from monkeys, through apes, to humans. This model was selected among the postural behaviours that were roughly antecedent to Hominidae bipedalism. So it was possible to abstract an Ape-like anteriorly sloping being, who under the above descr...Continue Reading

Biomechanics

Biomechanics examines the generation of internal forces within the body and investigates the effects and control of forces that act on or are produced on tissues. Here are the latest discoveries.
