Children, especially younger, are recognized as very susceptible to environmental lead exposure. In order to assess the effect of lead on spontaneous postural sway, we studied 327 children 4-13 years old, living in 4 cities in Upper Silesia an industrial region of Poland. Lead concentration in blood was measured by absorption atomic spectrometry (AAS) and posturography was performed using CATSYS 2000 - SWAY 7.0 equipment. Children's postural sway characteristics decreased with age. Particular variables had higher values for boys than girls and were positively associated with blood lead levels. There was an association between postural sway characteristics and smoking habits of mother, usage of aminoglycosides and paracetamol. Posturography seems to be a useful tool for assessment of lead exposure effects on the nervous system at low blood lead levels.

We investigated the effects of aging on postural muscles covariate patterns prior to voluntary perturbations. Nine healthy young and nine older subjects were instructed to release a load in a self-paced manner. The results of cross-correlation analyses showed that the average time lag corresponding peak correlation coefficient between trunk flexor and extensor muscles in the older group was significantly shorter, compared to that in the young group. The results of principal component analysis showed that the co-contraction Muscle-modes in the older group were observed more frequently than those in the young group. These results indicate that the older group showed changes in the anticipatory postural muscle co-variation, suggesting the transition from reciprocal to co-activation pattern with aging.

Alpine skiing is one of the most popular leisure time winter sporting activities. Skiing imposes high requirements concerning physical fitness, particularly regarding balance abilities. The main objective of this study was to evaluate the changes in balance performance of recreational skiers after a seven-day ski camp. A total of 78 students - 24 women and 54 men - participated in the study. The ski course was held in accordance with the official program of the Polish Ski Federation. The study sample was comprised of 43 beginners and 35 intermediate skiers. All students were tested with the MFT S3-Check, the day before and the day after the ski camp. The test system consisted of an unstable uniaxial platform, with an integrated sensor and corresponding software. Changes in balance performance (sensory and stability index) were evaluated using paired t-tests. Additionally, changes in sensory and stability categories, which were based on the norm data, were analyzed. Female and male participants showed significantly better sensory and stability indices after skiing. Considerable changes from weak or very weak to average or good balance categories could be seen after skiing for both sexes. Regarding skiing experience, both beginners and intermediate skiers improved their sensory and stability indices significantly after skiing. Hence, recreational alpine skiing resulted in better balance performance regardless of sex or skiing experience. Skiing as an outdoor activity offers the opportunity to improve balance performance with a positive impact on everyday life activities.

Introduction. In the initial phase of ski lessons, the skier encounters a completely new situation. The maintenance of body stability, which is influenced by various factors, attracts his entire attention. The aim of this study was to define the impact of ankle joint stiffening by ski equipment on the maintenance of body balance. Material and methods. The research was conducted on 13-member group aged 20 to 24. All the subjects were male students at the Faculty of Physical Education and Sport in Bia³a Podlaska (graduates of the ski instructor course). Each participant carried out three postural exercises on the KISTLER dynamometric platform. Then the same exercises were performed with ski boots and skis. Two parameters were used for the analysis of body balance, namely the COP path length and the surface area of the stabilogram. Results. It was stated in the study that ankle joint stiffening while standing on both skis did not have a negative impact on the postural stability. In majority of the tested subjects while standing on one ski, a considerable increase in the both analysed parameters occurred in relation to the same exercises performed without ski boots. That being so, it can be inferred that ski equipment causes deterioration of body stability. Moreover, it was noticed as a result of putting on ski boots and skis that body fluctuations increased slightly in relation to the growth of the base of support defined by the ski length and ski width setting. Conclusions. On this basis, it was concluded that ski equipment does not have a negative influence on the maintaining body balance. The growth of body fluctuations during exercises is insignificant in relation to the increase of body base area. It is necessary to find new ways of compensating for body fluctuations in order to maintain body balance with ski equipment on.

Introduction Morphological asymmetry is understood as a disruption of symmetry of external body shapes on both sides of the median plane. Slight deviations in body posture do not influence significantly on the proper body functioning, and a significant deviations may pose a threat to the proper functioning of the body. Aim of this study was to determine whether the asymmetry of scapulas affects the values of selected parameters of movement of the feet pressure center. Material and methods: 180 children (between the age of 7 and 10 years) participated in the study. The study group has been chosen based on photogrammetric study, which consisted of children with asymmetric scapulas sizes 10-20 mm (group I: 30 children). In the comparison group (group II) there was 30 randomly selected children qualified, without asymmetric scapula. Standing balance was assessed in the trial with eyes open, by using stabilometric platform. Six different motion parameters of center of pressure (COP) have been evaluated. Results: The analysis of the results of the study showed no statistically significant correlation between asymmetry of scapula and balance worsening. Conclusions: Among children with a small asymmetry of scapula, the behavior of the movement of center of pressure do not differ significantly from the analogous parameters among children showing no asymmetry. Gender of children doesn’t affect the behavior of the movement of center of pressure.

Introduction: Balance difficulties are one of the factors that have a negative impact on the daily activity of elderly people, which in turn lowers their quality of life. Aim: evaluation of the differences in static and dynamic postural stability in young, elderly and with vision loss women. Material and methods: Eighty-three female volunteers were divided into three groups: 26 young women (20,2 ± 1,75), 26 elderly (68,7 ± 7,55) and 15 pupils with vision loss (19,2±1,78). The following parameters were analysed from Accusway and BBS platforms. Results: A comparison of results with visual inspection between a group of young and elderly women showed statistically significant differences in terms of stabilogram ellipse area and maximal postural s way in ML direction. These two groups differ significantly in all parameters from BBS platform. The greatest differences are observed on a dynamic ground (p<0,001). Women with visual loss achieved the best results of path COP with eyes closed (37,01±6,73), the worst results were observed in a group of elderly women (49,59±21,04). They also did not perform any tasks on a dynamic ground without visual inspection. Women with visual loss achieved significantly worse results than young group. Conclusions: Greater balance control system involvement is observed in dynamic tests, which seem to be more appropriate and can detect disturbances earlier than static tests. Tests with changeable stability of the platform and without visual inspection that differentiate the groups seem to be particularly useful.

Introduction: Postural instability is important element of clinical presentation of patients with Parkinson disease. Objective of study was stabilometric evaluation of posture of patients with PD in comparison with healthy ones. Material and methods: 43 patients with PD and 46 healthy persons entered the study. TecnoBody platform was used for stabilometric assessment. Posture stability assessment was performed with and without patient’s sight control. Patients with PD were tested in “on” mode. Results: The results of open eyes test in patients with PD were: P-T speed 11,86 ± 12,5 m/s, P-B speed 8,49±7,4 m/s, perimeter 385,3±368,2mm, ellipse field 388,58 ±658,6mm2. Results obtained in the eyes closed test were: P-T speed 20,44±18 m/s, P-B speed 13,09±10,5 m/s, perimeter 637,21 ±530,9mm, ellipse field 756,16±888,7mm2. Results in healthy controls in open eyes test were: P-T speed 5,23±2 m/s, P-B speed 4,26±1,7 m/s, perimeter 176,67 ±66mm, ellipse field 100,23 ±71,1mm2. Fairly results obtained in eyes shut test were: P-T speed 10,28±4,4 m/s, P-B speed 5,91±3 m/s, perimeter 296,26 ±123,9mm, ellipse field 218 ±140,7mm2. Statistically significant differences (p<0,05) between groups in all four stabilometric parameters in both tests were recorded. Conclusions: 1. Increased deflection of body’s center of gravity in patients with PD causes imbalance which may be a reason of any falls. 2. Positive correlation was observed between age and perimeter values in control group in tests with eyes closed and opened. The correlation was not observed in tested group.

Wprowadzenie: Pionowa postawa ciała stanowi unikalną cechę człowieka, zależną od wielu czynników. Kinesiotaping jest stosowany w celu poprawy stabilności stawu skokowo-goleniowego, natomiast skuteczność takiej aplikacji, jak się wydaje w odniesieniu do stabilności ciała w pozycji stojącej nie została wystarczająco zweryfikowana w badaniach naukowych. Cele: Ocena wpływu kinesiotapingu stawu skokowo-goleniowego na parametry stabilometryczne u młodych, zdrowych kobiet. Materiał i Metody: W badaniu wzięło udział 50 zdrowych kobiet (średni wiek 21,12 ±1,83). Badane zostały losowo podzielone na dwie grupy: tejpowaną (grupa T) i kontrolną (grupa K). W grupie badanej wykonano aplikację kinesiotapingu w formie stosowanej po skręceniach stawu skokowo-goleniowego zarówno inwersyjnych, jak i ewersyjnych. Badane kobiety zostały poddane 4-krotnej próbie Romberga trwającej 2 minuty na platformie stabilometrycznej Alfa AC International East. Dwie próby przeprowadzono przed naklejeniem aplikacji kinesiotapingu i kolejno dwie próby: z plastrowaniem (grupa T) bądź bez oklejania (grupa K). Wyniki: Istotne statystycznie różnice pomiędzy grupami stwierdzono w parametrach: średnia prędkość ścieżki X przy oczach otwartych; 0,06 cm/s (p=0,0002), średnia prędkość Y przy oczach otwartych; 0,07 cm/s (p=0,0001), długość ścieżki przy oczach otwartych; 5,78 cm (p=0,0001) i pole powierzchni przy oczach otwartych; 0,58 cm2 (p=0,0002) oraz w parametrach: średnia prędkość X przy oczach zamkniętych; 0,10 cm/s (p=0,0004), średnia prędkość Y przy oczach zamkniętych; 0,11 cm/s (p=0,0004) oraz w długości ścieżki przy oczach zamkniętych; 0,43 cm (p=0,0004). Wnioski: U młodych, zdrowych kobiet poddanych aplikacji kinesiotapingu stwierdzono korzystną zmianę parametrów stabilometrycznych wskazującą na większą stabilność stawu skokowo-goleniowego w porównaniu do grupy, u której metoda ta nie była stosowana.

Introduction: The upright posture uniquely characteristic of humans is dependent upon many factors. Kinesio Taping is used to enhance ankle joint stability, but its effectiveness in relation to body stability in a standing position has not yet been verified in scientific research. Objectives: Assessment of the effect of ankle Kinesio Taping on stabilometric parameters in young, healthy women. Material and Methods: The study included 50 healthy women (mean age 21.12 ±1.83 years) who were randomly assigned to two groups: the taping group (group T) and control group (group C). In the taping group Kinesio Taping was applied according to the method used in ankle sprains (both inversion and eversion). The women performed the Romberg test four times with each trial lasting two minutes on an Alfa AC International East stabilometric platform: two tests without Kinesio taping intervention and two further tests with (group T) or without taping (group C). Results: Significant differences between the groups were observed in the following parameters: mean speed in the sagittal plane with eyes open; 0.06 cm/s (p=0.0002), mean speed in the frontal plane with eyes open; 0.07 cm/s (p=0.0001), total path length with eyes open; 5.78 cm (p=0.0001) and sway area with eyes open; 0.58 cm2 (p=0.0002) and in parameters: mean velocity in the sagittal plane with eyes closed; 0.10 cm/s (p=0.0004), mean velocity in the frontal plane with eyes closed; 0.11 cm/s (p=0.0004) and in total path length with eyes closed; 0.43 cm (p=0.0004). Conclusions: In young, healthy women who received Kinesio Taping, favourable changes in stabilometric parameters were found indicating better ankle stability than in the group without taping.
