Morphofunctional changes in distribution of pressure center in multiple sclerosis.

Introduction: Gait evaluation and assessment of motor performance are of utmost importance in the clinical management of multiple sclerosis (MS). A new approach to the analysis of static and dynamic balance of MS patients is the use of complex biomechanical analysis that includes an analysis of the distribution of the center of pressure (DCP) and loading, measured by using the pressure and force platforms.

Patients And Methods: The study was conducted on a total of 18 patients with MS, with the mean age of 41.

Prediction of motor disorders in multiple sclerosis using muscle change structure assessment.

Introduction: The neuropathogenesis of multiple sclerosis (MS) lesions has been explained by several mechanisms, which emphasize the unpredictable nature of these lesions. The aim of this study is to present the neuromuscular changes in MS at the patients without gait or motor disorders using a noninvasive method named tensiomyography (TMG).

Patients And Methods: The studied group included a number of seven MS patients without clinically detected gait disorders, with mean age of 33.

Analysis of neuromuscular parameters in patients with multiple sclerosis and gait disorders.

Unlabelled: Gait is a motor activity that requires understanding the dynamics and functional anatomical elements that make possible its cyclical conduct. Patients with multiple sclerosis record impaired balance and gait due to the process of demyelination, disorders that can be estimated by quantifying neuromuscular and cortical parameters. The aim of this paper is to present both an analysis of these parameters in the thigh muscles and an evaluation of cortical parameters obtained by visual evoked potentials (VEP).

New approaches to cancellous bone bio-modeling.

The purpose of our research is to develop a model of cancellous bone that would allow us to forecast the changes in this structure under various mechanical forces and to simulate the dynamics of the cancellous bone behavior under these circumstances. At the same time, the suggested model will allow the measurement of the tension/forces applied onto the bone structure, with the purpose of comparing these with the in vitro values, identification of the areas with increased trauma risk, and simulation of the behavior of cancellous substance under different mechanical stimuli, which affect the growth and aging of the bone, as well as to study the materials used in endoprostheses. Two groups of methods have been used for this purpose: micro-anatomical methods - for the visualization of bone structures, and bio-mathematical methods (finite element method) - for the modeling of these structures.
