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.

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.

Before And After

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.

This study was executed to explore correlation between postural alignment in standing measured through photogrammetry and static balance in children with visual, hearing, intellectual and physical disability. METHODS: Participants were 34 children (age 7-12 years) including 8 children with hearing, 8 with visual, 6 with physical, and 12 children with intellectual disabilities Postural alignment in standing was measured through photogrammetry. Static balance data were obtained in 15 s bipedal stance with eyes open and eyes closed, and also in 10 s unipedal stance. A force plate was used to collect data of Centre of Pressure amplitude in anterior-posterior, medio-lateral directions and velocity. Correlation was obtained using Spearman's Rank Correlation co-efficient in SPSS software (version 19.0). RESULTS: Moderate positive correlation (r = 0.338 to r = 425; p ≤ 0.05) was found between angle of head position and angle of frontal and sagittal ASIS and PSIS level. Also, moderate positive correlation was found between angles in shoulder level and angles of the head (r =  .365 to r = .453, p < .05). In assessing the static balance outcomes between the four groups, results presented significant differences in results during bipedal stance with eyes open. CONCLUSION: Degree of forward head posture correlates directly with hip and shoulder anatomical placement. Children with intellectual disability presented larger displacement of the center of pressure with more body sway observed during eyes open condition.

AbstractWhen prescribing balance exercises to athletes in different sports, it may be important to recognize performance variations. Indeed, how athletes from different sports perform on balance tests is not well understood. The goal of the present study was to compare static balance and the role of vision among elite sprinters, jumpers and rugby players. The modified clinical test of sensory interaction on balance (mCTSIB) was used to assess the velocity of the center-of-pressure (CoP) on a force platform during a 30 s bipedal quiet standing posture in 4 conditions: firm surface with opened and closed eyes, foam surface with opened and closed eyes. Three-factor ANOVA indicated a significant main effect for groups (F=21.69, df=2, p<0.001, η2 = 0.34). Significant main effect of vision (F=43.20, df=1, p<0.001, η2 = 0.34) and surface (F=193.41, df=1, p<0.001, η2 = 0.70) as well as an interaction between vision (eyes open, eyes closed) and surface (firm and foam) (F=21.79, df=1, p=0.001) were reported in all groups. The subsequent Bonferroni-Dunn post hoc test indicated that rugby players displayed better static balance than sprinters and jumpers (p=0.001). The comparison of sprinters and jumpers did not reveal significant differences (p>0.05). The nature of the sport practiced and the absence of visual control are linked to modify static balance in elite athletes. Coaches and strength and conditioning professionals are recommended to use a variety of exercises to improve balance, including both exercises with opened and closed eyes on progressively challenging surfaces in order to make decisions about tasks and sensory availability during assessment and training.

Abstract Background Ankylosing spondylitis (AS) is a chronic inflammatory rheumatic disease that leads to a limitation of mobility, which can cause postural deficits and progressive loss of balance. Aquatic exercise improves this health condition. The objetive is to verify the influence of an aquatic exercise program, on balance and functionality, in individuals with AS. Methods Pre-experimental study carried out on 6 individuals with AS. All individuals were assessed at baseline (M0) and 12 weeks after the intervention (M1) using the Bath indices (BASMI, BASFI and BASDAI) and the balance assessment protocol (‘Body Sway’) by the Physiosensing Platform. Data were analyzed using the Statistical Program Statistical Package for the Social Sciences (SPSS), version 26. Were used descriptive statistics and Wilcoxon test to compare M0 and M1. The significance value was 0.05. Results We verify improvements in BASMI (P = 0.046), BASFI (P = 0.042) and BASDAI (P = 0.027) scores. Through the analysis of the center of pressure variables, there were no statistically significant differences, between moments, in the protocol. However, when assessing balance, in the anteroposterior mean distance in both the protocol (eyes open) and in the protocol (eyes closed), in the root mean square in both protocols and in mediolateral mean velocity, only in the protocol (eyes open), there was a slight decrease in the median value. Conclusions The present study suggests that the specific aquatic exercise program, may influence balance and improve functionality in a population with AS. Therefore, the Bath indices translate improvements in the symptoms and functionalities of these participants.

We explored if adolescents with Gilles de la Tourette syndrome (GTS) had functional postural control impairments and how these deficits are linked to a disturbance in the processing and integration of sensory information. We evaluated the displacements of the center of pressure (COP) during maximal leaning in four directions (forward, backward, rightward, leftward) and under three sensory conditions (eyes open, eyes closed, eyes closed standing on foam). GTS adolescents showed deficits in postural stability and in lateral postural adjustments but they had similar maximal COP excursion than the control group. The postural performance of the GTS group was poorer in the eyes open condition (time to phase 1 onset, max-mean COP). Moreover, they displayed a poorer ability to maintain the maximum leaning position under the eyes open condition during mediolateral leaning tasks. By contrast, during forward leaning, they showed larger min-max ranges than control subjects while standing on the foam with the eyes closed. Together, these findings support the idea that GTS produces subclinical postural control deficits. Importantly, our results suggest that postural control disorders in GTS are highly sensitive to voluntary postural leaning tasks which have high demand for multimodal sensory integration.

Context Altered biomechanics displayed by individuals with chronic ankle instability (CAI) is a possible cause of recurring injuries and posttraumatic osteoarthritis. Current interventions are unable to modify aberrant biomechanics, leading to research efforts to determine if real-time external biofeedback can result in changes. Objective To determine the real-time effects of visual and auditory biofeedback on functional-task biomechanics in individuals with CAI. Design Crossover study. Setting Laboratory. Patients or Other Participants Nineteen physically active adults with CAI (7 men, 12 women; age = 23.95 ± 5.52 years, height = 168.87 ± 6.94 cm, mass = 74.74 ± 15.41 kg). Intervention(s) Participants randomly performed single-limb static balance, step downs, lateral hops, and forward lunges during a baseline and 2 biofeedback conditions. Visual biofeedback was given through a crossline laser secured to the dorsum of the foot. Auditory biofeedback was given through a pressure sensor placed under the lateral foot and connected to a buzzer that elicited a noise when pressure exceeded the set threshold. Cues provided during the biofeedback conditions were used to promote proper biomechanics during each task. Main Outcome Measure(s) We measured the location of center-of-pressure (COP) data points during balance with eyes open and eyes closed for each condition. Plantar pressure in the lateral column of the foot during functional tasks was extracted. Secondary outcomes of interest were COP area and velocity, time to boundary during static balance, and additional plantar-pressure measures. Results Both biofeedback conditions reduced COP in the anterolateral quadrant while increasing COP in the posteromedial quadrant of the foot during eyes-open balance. Visual biofeedback increased lateral heel pressure and the lateral heel and midfoot pressure-time integral during hops. The auditory condition produced similar changes during the eyes-closed trials. Auditory biofeedback increased heel pressure during step downs and decreased the lateral forefoot pressure-time integral during lunges. Conclusions Real-time improvements in balance strategies were observed during both external biofeedback conditions. Visual and auditory biofeedback appeared to effectively moderate different functional-task biomechanics.

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.

Posture Stability

The effects of different factors—such as age, sex, performance level, and athletic shoe features—on postural balance in athletes remain unclear. The main objective of our study is to identify the features of postural stability in athletes of different age, sex, performance level, and using different types of athletic shoes. This study assessed postural stability in athletes (n = 936, 6–47 years) in a normal bipedal stance with eyes open (EO) and eyes closed (EC). Postural stability was evaluated based on the center of pressure (COP), sway area (AS), and velocity (VCP) while standing on a stabiloplatform. Children (6–12 years) and teen athletes (13–17 years) showed reduced AS-EO (p < 0.01) and VCP-EO (p < 0.01) compared to control (n = 225, 7–30 years). In male and female athletes aged 18+, only VCP-EC was lower versus control. In females (13–17 and 18+), VCP-EO and EC were lower than in males (p < 0.05). Only in the Shooting group, the athletes’ performance levels had an effect on VCP-EO (p = 0.020). Long use of rigid athletic shoes with stiff ankle support was associated with reduced posture stability. Postural stability in athletes was mostly influenced by the athlete‘s age, and, to a lesser extent, by their sex, performance level, and athlete shoe features.
