The purpose of the study was to compare postural control in static standing in young adults with and without Down syndrome (DS), with eyes closed and eyesopen, before and after an 18-wk dance-based training program. The study included 11 young people with DS age 20.5 (1.3) yr and 11 without DS age 20.2 (2.0) yr.All parameters were recorded before and after the training program. Parameters related to center of pressure (COP; closed and open eyes) were recorded from aplatform with the participant in bipedal standing position during 30 s. The results suggest that young people with DS have worse COP control in both visual conditions (closed and open eyes) and are affected by visual information in a different way than their peers without DS. In the group of young adults with DS, thedance-based training program improved some parameters related to the use of visual input in controlling COP.

The ability to maintain static balance in badminton players may decrease due to prolonged asymmetric locomotor loads while training. The aim of this study was to assess the peculiarities of maintaining static balance in badminton players of various age and qualification groups. Materials and Methods. The study involved 88 badminton players, who had various sports experience and skills. Static balance was assessed with a stabilographic hardware-software complex “Stabilan 01-2” and the Romberg test (eyes open/eyes closed) during the preparatory and transitional periods of the annual training cycle. The authors assessed the following indicators: MO(x), mm; MO(y), mm. Statistical data processing was carried out using Microsoft Excel and STATISTICA 8.0 data analysis package. To compare the samples, we used the parametric Student’s t-test. Normality of distribution was checked with the Shapiro-Wilk test. Statistical data represented both arithmetic mean and standard error of the mean. The parameters were considered statistically significant at p<0.05. Results. Badminton players of all groups under consideration demonstrated an asymmetry of the vertical posture with center-of-pressure movement to the right in both tests (eyes open/eyes closed) (p<0.05). In badminton players, aged 8–12, the posture stereotype was characterized by a forward center-of-pressure movement (p<0.05), in adolescents, aged 13–16, and young people, aged 17–21, we observed backward center-of-pressure movement (p<0.05). Conclusion. Badminton players, aged 8–12, demonstrated a higher level of maintaining static balance with visual control. Adolescents and young people are able to maintain body balance with visual deprivation, which, apparently, indicates more perfect mechanisms of proprioceptive and tactile sensitivity. Keywords: badminton, asymmetric motor loads, static balance. Способность к сохранению статического равновесия тела у бадминтонистов может снижаться вследствие длительных асимметричных двигательных нагрузок в тренировочном процессе. Целью исследования явилась оценка особенностей сохранения статического равновесия у бадминтонистов различных возрастно-квалификационных групп. Материалы и методы. В исследовании приняло участие 88 бадминтонистов различного спортивного стажа и квалификации. Статическое равновесие тела оценивалось с помощью стабилографического аппаратно-программного комплекса «Стабилан 01-2» с использованием пробы Ромберга в тесте с открытыми и закрытыми глазами в подготовительный и переходный периоды годичного тренировочного цикла подготовки. Оценивались следующие показатели: MO(x), мм; MO(y), мм. Статистическая обработка данных проводилась с использованием программы Microsoft Excel и пакета анализа данных Statistica 8.0. Для сравнения выборок использовался параметрический t-критерий Стьюдента. Нормальность распределения проверялась с помощью критерия Шапиро–Уилка. Статистические данные представлены как среднее арифметическое и стандартная ошибка среднего. Исследуемые параметры считались статистически значимыми при p<0,05. Результаты. У бадминтонистов всех исследуемых групп отмечена асимметрия вертикальной позы с девиацией центра давления вправо как в тесте с открытыми, так и в тесте с закрытыми глазами (р<0,05). У бадминтонистов группы второго детства (8–12 лет) стереотип позы характеризовался смещением центра давления вперед (р<0,05), у испытуемых подросткового (13–16 лет) и юношеского (17–21 год) возрастов отмечена девиация центра давления назад (р<0,05). Выводы. Для бадминтонистов группы второго детства при зрительном контроле характерен более высокий уровень сохранения статического равновесия, тогда как спортсмены подросткового и юношеского возрастов и при депривации зрения способны удерживать равновесие тела, что, по-видимому, указывает на более совершенные механизмы проприоцептивной и тактильной чувствительности. Ключевые слова: бадминтон, асимметричные двигательные нагрузки, статическое равновесие.

AbstractBackground: The purpose of this study was to compare body balance in road and off-road cyclists, immediately before and after the racing season.Material/Methods: Twenty individuals participated in the study and they were divided into two groups: specialists in road-cycling (n = 10) and in off-road cycling (n = 10). Immediately before and after the five-month racing season stabilographic trials were carried out (at rest and after progressive exercise). In assessing body balance the distance and velocity of the centre shifts (in the anterior-posterior and left-right direction) were analysed. The tests were performed with the cyclists’ eyes open, eyes closed, and in feedback.Results: After the racing season, in the off-road cyclists’ group, distance and velocity of the centre of pressure shifts increased after a progressive exercise.Conclusions: In the off-road cyclists’ group the balance of the body in the sagittal plane deteriorated after the racing season. Moreover, after the racing season off-road cyclists were characterized by a worse balance of the body, compared to road cyclists

Balance disorders have a high prevalence among elderly people in developed countries, and falls resulting from balance disorders involve high healthcare costs. Therefore, tools and indicators are necessary to assess the response to treatments. Therefore, the aim of this study is to detect relevant changes through minimal detectable change (MDC) values in patients with balance disorders, specifically with vertigo. A test-retest of a static and dynamic balance test was conducted on 34 healthy young volunteer subjects using a portable stabilometric platform. Afterwards, in order to show the MDC applicability, eight patients diagnosed with balance disorders characterized by vertigo of vestibular origin performed the balance test before and after a treatment, contrasting the results with the assessment by a specialist physician. The balance test consisted of four tasks from the Romberg test for static balance control, assessing dynamic postural balance through the limits of stability (LOS). The results obtained in the test-retest show the reproducibility of the system as being similar to or better than those found in the literature. Regarding the static balance variables with the lowest MDC value, we highlight the average velocity of the center of pressure (COP) in all tasks and the root mean square (RMS), the area, and the mediolateral displacement in soft surface, with eyes closed. In LOS, all COP limits and the average speed of the COP and RMS were highlighted. Of the eight patients assessed, an agreement between the specialist physician and the balance test results exists in six of them, and for two of the patients, the specialist physician reported no progression, whereas the balance test showed worsening. Patients showed changes that exceeded the MDC values, and these changes were correlated with the results reported by the specialist physician. We conclude that (at least for these eight patients) certain variables were sufficiently sensitive to detect changes linked to balance progression. This is intended to improve decision making and individualized patient monitoring.

Context:Although reliability is a population-specific property, few studies have investigated the measurement error associated with force-platform parameters in athletic populations.Objective:To investigate the skill-related differences between athletes and nonathletes in reliability of center-of-pressure (COP) summary measures under eyes-open (EO) and eyes-closed (EC) conditions.Design:Test–retest reliability study.Setting:COP was recorded during double-leg quiet standing on a Kistler force platform before and after a fatiguing treadmill exercise, with EO and EC.Participants:31 male participants including 15 athletes practiced in karate and 16 nonathletes.Main Outcome Measures:Standard deviation (SD) of amplitude, phase-plane portrait, SD of velocity, mean total velocity, and area were calculated from 30-s COP data. Intraclass correlation coefficient (ICC), standard error of measurement, and coefficient of variation (CV) were used as estimates of reliability and precision.Results:Higher ICCs were found for COP measures in the athlete (compared with the nonathlete) group, postfatigued (compared with prefatigued) condition, and EC (compared with EO) tests. CVs smaller than 15% were obtained for most of the COP measures. SD of velocity in the anteroposterior direction showed the highest reliability in most conditions.Conclusions:Tests with EC and to a lesser extent tests performed in the athlete group and in the postfatigued condition showed better reliability.

The purposes of the present study were a) to establish postural control profiles for individuals 6–12 years of age, b) to analyze the participants’ characteristics (age, sex, weight, height, and physical activity) in those profiles, and c) to analyze the influence of visual information in the profiles found. Two hundred and eight typically developing children aged 6–12 years performed two trials in bipedal standing position with eyes open and closed. Feature extraction involved time, frequency, and sway-density plot variables using signals from the center of pressure. A Self-Organizing Map was used to classify and visualize the values of the participants in all the postural control variables tested. A k-means cluster analysis was applied to generate a small number of postural control profiles. The results determined six postural control profiles; three with participants denoting high stability and three considered as low stability profiles. Age, sex, and height were related to the postural control profiles. Boys were more frequently allocated in high stability clusters than girls, while the other factors yielded unclear difference between high and low stability profiles. The analysis of children’s profiles reflecting postural stability should therefore involve more than one factor including the individuals’ age, sex, and height.

The effectiveness of the visual feedback to improve ability with the sense and muscular strength of human in our bicycle system was quantitatively verified in our study. Experiments were performed to find the factors related to the training of equilibrium sense. The subjects consisted of young and the aged and the group of young people was compared against the group of the aged. We investigated three different training modes, non-visual feedback (NVF), visual feedback of the weight (VFW), and visual feedback of the center of pressure (VFC) and measured the riding time and speed, the weight shift, and the center of pressure (COP) for twenties and seventies. The results showed that the running capability of the young and the aged became much better after repeated training. In addition, it was found out that the ability to control postural balance and the capability of equilibrium sense were improved with the presentation of the visual feedback information. These results will be effective in the diagnosis of equilibrium sense and vestibular function with the aged.

Background: People with Down syndrome present skeletal abnormalities in their feet that can be analyzed by commonly used gold standard indices (the Hernández-Corvo index, the Chippaux-Smirak index, the Staheli arch index, and the Clarke angle) based on footprint measurements. The use of Photoshop CS5 software (Adobe Systems Software Ireland Ltd, Dublin, Ireland) to measure footprints has been validated in the general population. The present study aimed to assess the reliability and validity of this footprint assessment technique in the population with Down syndrome. Methods: Using optical podography and photography, 44 footprints from 22 patients with Down syndrome (11 men [mean ± SD age, 23.82 ± 3.12 years] and 11 women [mean ± SD age, 24.82 ± 6.81 years]) were recorded in a static bipedal standing position. A blinded observer performed the measurements using a validated manual method three times during the 4-month study, with 2 months between measurements. Test-retest was used to check the reliability of the Photoshop CS5 software measurements. Validity and reliability were obtained by intraclass correlation coefficient (ICC). Results: The reliability test for all of the indices showed very good values for the Photoshop CS5 method (ICC, 0.982–0.995). Validity testing also found no differences between the techniques (ICC, 0.988–0.999). Conclusions: The Photoshop CS5 software method is reliable and valid for the study of footprints in young people with Down syndrome.

Aims. Vestibular system is indicated as one of the most important sensors responsible for static and dynamic postural control. In this study, we evaluated static balance in patients with unilateral vestibular impairments.Materials and Methods. We compared static balance control using Kistler force plate platform between 10 patients with unilateral vestibular impairments and 20 normal counterparts in the same sex ratio and age limits (50±7). We evaluated excursion and velocity of center of pressure (COP) and path length in anteroposterior (AP) and mediolateral (ML) planes with eyes open and with eyes closed.Results. There was no significant difference between COP excursions in ML and AP planes between both groups with eyes open and eyes closed (pvalue > 0.05). In contrast, the difference between velocity and path length of COP in the mentioned planes was significant between both groups with eyes open and eyes closed (pvalue < 0.05).Conclusions. The present study showed the static instability and balance of patients with vestibular impairments indicated by the abnormal characteristics of body balance.
