Scientific Expertise:

  • Anatomy Biomechanics - Modeling


  • Anatomy’s functional approach omits to take into consideration conjunctive structures that are currently little-known, and have been poorly studied so far. The terms used to define them remain imprecise and open to interpretation. The roles of those structures are too approximatively and only partially taken into consideration within the approach of the human motion, while their anatomical study suggests a significant intervention in the deformability of members and trunk while in motion. Spotting them and studying their mechanical properties would shed light on what remains a black spot in the field of functional anatomy exclusively based on bone parts, joints and their mechanical mobilities. This approach should be made in light of embryology, where the organogenesis is carried out by the build-up of conjunctive layers that go along with the positioning and specialization of tissues. Studying their properties and behaviors will lead to finer modeling of humain movement and of its rehabilitation derivatives.}
  • The conjunctive structures show the deformations of the body while in motion, but also while under maintained tension, which is a pain factor. The manual therapy used for the care of patients suffering from chronic pain necessarily puts a strain on the conjunctive structures attached to the contractile structures. The sensations and functional results of those maneuvers required experimental objectivation, that could be considered based on electromyographic recordings and modifications of posture and codified behavior.
