Abstract

Introduction. Equilibrioception – or sense of balance – is dependent on a number of features of the nervous system and motor system. A rotational sense of balance is fully developed at around 6 years of age; static and dynamic balance, however, is achieved at about 12 years of age.
Purpose. This paper aims to identify dimorphic differences of postural static stability in children of the same age range.
Research Material and Method. Material: The research group consisted of 450 children aged 9 to 12, comprising 235 girls and 215 boys. Research method: The measurement of the Centre of Pressure Sway Path length (mm) and the Sway Area size (mm2) with Eyes Open and Eyes Closed (EO/EC) using CQ-STAB device. The results have been subjected to statistical analysis.
Results. The results obtained did not present a normal distribution and therefore non-parametric tests were used for the calculations. The analysis shows that girls, when compared with boys, achieved significantly better results in static stability measured by determining both the Sway Path and the Sway Area of the COP, both in EO and EC conditions.
Conclusions. Research results analysis indicated a better postural static stability in females compared to male research participants. Gender differences were observed in the study in both Eyes Open and Eyes Closed conditions; this may indicate functional developmental variability of the central nervous system responsible for postural stability control in girls and boys.

Abstract
The aim of this study is to explain the differences between balance and postural stability, and the changes which occur in these traits in patients after stroke.
Human being has the natural ability to stand on two feet and to move on the two feet across an unfamiliar terrain. However these abilities do constitute a big challenge for the balance control system, which is being controlled through the three separate systems, two of which are sight, responsible for planning of the locomotion activity, vestibular system, responsible for spatial orientation of the human body. The third, and the most complex is the sensory system (composed of proprioceptors and mechanoreceptors). In terms of biomechanics the balance is defined as the ability to maintain the center of gravity of the human body above the supporting plane.
One of the most important determinants of the correct body posture is the postural stability, which wider concept and denotes the ability to recover the balance. This is possible thanks to three strategies. Patients after a stroke have a problem with the ability of spontaneous kinesthetic response. The distribution of pressure forces of the plantar side of a foot on the ground changes, it becomes difficult to maintain balance, and the consequences are frequent falls, femur fractures and problems with the basic activities of daily living.

E. Kamińska, S. Porzucek, M. Wiernicka, M. Goliwąs, J. Lewandowski – Functional assessment of movement patterns in selected martial arts and sports contestants, using the test Functional Movement Screen™. FP 2016; 16(3); 42-49

Abstract
Purpose of this study. Functional Movement System™ is a concept created by Cook and Burton, that allows functional evaluation of movement patterns. The purpose of this study was to compare movement patterns in contestants of the three sports disciplines, determination of weak links in the cinematic chain.   Additionally, it was attempted to determine which motor organ is most exposed to incorrect movement patterns in contestants of individual disciplines.
Material and methods. In the study evaluation included movement patterns of 60 contestants that train box, judo and kickboxing by means of FMS™, including 20 women and 40 men, at the age from 18 to 30 years. The investigated persons were divided in three groups, where qualification criterion for each group was type of trained martial art or sport and training seniority.
Results. Difference between boxers, kickboxers and judokas were observed only within individual movement patterns. Their global quality was comparable for all persons.
Conclusions. Final results of FMS™ test were not statistically significantly different due to type of trained martial art or sport. In judokas it the most asymmetry was during individual tests, as many as 30% of investigated receive the lowest average result in FMS™ tests, that suggest implementation of corrective training. The areas that were most exposed in boxers and kickboxers appeared to be spine lumbar section and shoulder joint area, and in boxers only spine lumbar section.
