Introduction. Musculo-articular contracture of the lower jaw is a challenging issue in oral and maxillofacial surgery, despite extensive research this area. While condition presents diverse range clinical manifestations, it has received little attention literature, there are currently no clear diagnostic criteria available. The aim study to improve diagnosis musculo-articular contractures by ut...

Prediction and prevention of musculo-skeletal injuries is an important aspect of preventive health science. Using as an example a human knee joint, this paper proposes a new coupled– loading–rate hypothesis, which states that a generic cause of any musculo-skeletal injury is a Euclidean jolt, or SE(3)−jolt, an impulsive loading that hits a joint in several coupled degreesof-freedom simultaneous...

In this new column of the JMNI, we will give a six-monthly overview about new publications which, to our eyes, are interesting and relevant. Keeping in line with the 'spirit' of ISMNI, we take the freedom to discuss with a more holistic approach and most importantly, we encourage feed-back from the readers.

La maladie de Kaposi est une maladie angioproliferative multifocale, dont les localisations cutanéo-muqueuses sont les plus fréquentes. Nous en rapportons un cas avec une atteinte musculo squelettique. Patiente de 55 ans, présente depuis un an de multiples nodules angiomateux confluents en des tumeurs ulcéro bourgeonnantes sur un placard hyperpigmenté et oedème de la jambe gauche, associés à de...

Locomotion of an animal is generated through interactions among the nervous system, the musculo-skeletal system and the environment. We particularly focus on biomachine hybrid systems in order to understand dynamics of these interactions. We can modify balances of the interactions by bio-machine hybrid systems. In this study, we intend to deal with a frog cyborg driven by biological muscles.

This paper presents an Iterative Linear Quadratic Regulator (ILQR) method for locally-optimal feedback control of nonlinear dynamical systems. The method is applied to a musculo-skeletal arm model with 10 state dimensions and 6 controls, and is used to compute energy-optimal reaching movements. Numerical comparisons with three existing methods demonstrate that the new method converges substanti...

In this paper we propose an ∞−dimensional cerebellar model of neural controller for realistic human biodynamics. The model is developed using Feynman’s action– amplitude (partition function) formalism. The cerebellum controller is acting as a supervisor for an autogenetic servo control of human musculo–skeletal dynamics, which is presented in (dissipative, driven) Hamiltonian form. The ∞−dimens...
