“…Our study expanded our previous work on postural stability in children with neurodevelopmental disorders (Bucci et al, 2017a,b). Indeed, children with ADHD, dyslexia and ASD showed poor postural stability most likely due to a cerebellar dysfunction related to a deficiency into the cerebellar‐cortical network (Stoodley, 2016).…”

“…We observed that saccades had a tendency to increase the surface of the center of pressure in these children. We hypothesized that postural difficulties in children with neurodevelopmental disorders could be, most likely, due to poor use of sensory inputs to compensate natural body perturbation due to cerebellar impairment deficiencies in cerebro-cortical network (Bucci et al, 2017b).…”

In everyday life, our activities frequently involve the simultaneous performance of two or more tasks. Sharing attention between two concurrent tasks may result in a decrease in performance specifically among children with neurodevelopmental disorders. The objective of the study was to determine whether the influence of postural conditions (sitting condition, single task; standing condition, dual task) on eye movement performances on three visual tasks with high attentional load (visually-guided saccade task, memory-guided saccade task and fixation task) was different in children with neurodevelopmental disorders (attention deficit and hyperactive disorder, dyslexia, and high functioning autism spectrum disorder) when compared to typically developing children. One hundred and four children (26 per group, sex-age- and IQ-matched groups) were evaluated. We found that for the fixation task only, the three groups of children with neurodevelopmental disorders had poorer eye movements performances in the standing condition compared to the sitting condition while no such difference was found for typically developing children. We suggest that children with neurodevelopmental disorders have fewer attentional resources available for performing correctly oculomotor tasks with high attentional load leading to impairment of these tasks for maintaining a good level of postural stability.

“…It is generally assumed that posture control is based on the control of the centre of gravity of the body. Correct, stable posture is a prerequisite for carrying out most free movements and locomotion [16]. It also allows for the proper psychophysical development of a child.…”

Introduction: The analysis of somatic features is an important part of health assessment. Body mass, height, and the size of the support surface are determinants of static mechanical stability Aim of the research: To analyse canonical correlations between somatic features and postural stability in children aged 10-12 years. Material and methods: The study included 301 children aged 10-12 years. Body composition was assessed using the method of bioelectrical impedance analysis, which consists of the evaluation of resistance to the flow of an electric current. Postural stability was evaluated using the Biodex Balance System platform. Postural stability testing was performed with both feet positioned on a stable surface, with open eyes. Results and conclusions: Measurements of somatic traits and body composition, which were compared to norms, showed that the majority of subjects had normal somatic features and body composition. All children during the postural stability test were in research Zone A, and most of them tended to lean to the right and left back (Quadrant III, IV). There were significant correlations between somatic variables and postural stability. On the somatic variables side, the largest share was in body height and muscle mass (%), and the highest shares in the postural stability variables were the total stability index, the percentage of time spent in Quadrant III, and the percentage of time spent in Quadrant IV. Body height and muscle mass (%) were most strongly correlated with variable postural stability. Streszczenie Wprowadzenie: Analiza cech somatycznych jest ważnym elementem oceny stanu zdrowia dzieci. Masa ciała, wysokość i wielkość powierzchni podparcia są wyznacznikami statycznej stabilności mechanicznej. Cel pracy: Analiza korelacji kanonicznych między cechami somatycznymi a stabilnością posturalną u dzieci w wieku 10-12 lat. Materiał i metody: Badaniami objęto 301 dzieci w wieku 10-12 lat. Skład ciała oceniono metodą impedancji bioelektrycznej, która polega na ocenie oporności przepływu prądu elektrycznego. Stabilność postawy badano za pomocą platformy Biodex Balance System. Wykonano test stabilności postawy z obiema stopami ustawionymi na stabilnym tle z otwartymi oczami. Wyniki i wnioski: Pomiary cech somatycznych i składu ciała, które porównywano z normami, wykazały, że większość badanych miała prawidłowe cechy somatyczne i skład ciała. Wszystkie dzieci w czasie testu stabilności posturalnej znajdowały się w strefie badawczej A i większość z nich miała tendencję do wychylania ciała w prawy i lewy tył (kwadrat III, IV). Stwierdzono istotne korelacje między zmiennymi somatycznymi a stabilnością posturalną. Po stronie zmiennych somatycznych największy udział miały wysokość ciała i masa mięśni (%), a po stronie zmiennych stabilności posturalnej-całkowity indeks stabilności, procent czasu przebywania w III kwadracie i procent czasu przebywania w IV kwadracie. Wysokość ciała i masa mięśni (%) były najsilniej skorelowane ze zmiennymi stabilności posturalnej.

“…PII is = Σx Σy PI (F1, F2, F3)/CT (F1, F2, F3), where PI and CT are the spectral power index and cancellation time for each of the three frequency ranges (F1: from 0.05 to 0.5 Hz, F2: from 0.5 to 1.5 Hz, and F3: higher than 1.5 Hz). When PII is higher, the postural stability is weak 33 .…”

Autism Spectrum Disorders subjects (ASD) is characterized by postural control deficits. This study aimed to explore the effect of a short postural rehabilitation training program on postural capabilities in children with ASD. Two groups (G1 and G2) of twenty children with ASD of IQ-, sex-and age-matched (mean age 11.7 ± 2.4 years) were included in this study. Posture was recorded by using the Balance Quest from Framiral on unstable platform in three different viewing conditions. The rehabilitation program consisted in two distinct postural control training exercises. Postural recordings were performed twice at T1 and T2 for both groups of children. Between T1 and T2 a 6-minute postural training was performed by the G1 group only, while the G2 group had a 6-minute of rest. Children were allocated randomly to the G1 or G2 groups. At T1, postural instability was similar for both groups of ASD children (G1 and G2) desp+\ite viewing conditions. At T2, we observed an improvement of postural control related to a mixed effect of training rehabilitation but also of test-retest. Knowing the potential of new rehabilitation strategies, the impact of postural control deficit in ASD children needs to be reconsidered. Well design case-control studies are requested to ensure scientific validity of postural rehabilitation training program. Autism Spectrum Disorders (ASD) are neurodevelopmental disorders characterized by social communication and social interaction deficits, associated with the presence of restricted, repetitive and stereotyped behaviors 1. Sensorimotor deficits as well as fine and gross motor skill impairment are consistently reported in children with ASD and correlated with the severity of social communication impairment 2,3. Sensory abnormalities are frequently the earliest identifiable clinical features of developmental trajectory impairments 4,5. Similarly to social communication deficit, motor impairments may represent core features of autism when considering a broader spectrum of symptom 6. Several groups measured postural sway in children with ASD and showed that affected children were significantly more unstable than children with neurotypical development 7,8. A larger surface area of the center of pressure (COP) was observed in children with ASD with respect to control participants 9-13 , associated with an increased COP velocity 10,11,14. Postural instability in children with ASD was also more significant when somatosensory inputs were affected, such as standing on an unstable platform with foams under the feet or when wearing a vibrating apparatus on the neck 7,13,15-18. All of these studies reported a significantly larger body sway displacement and/or faster sway velocity in subjects with ASD compared to peers with typical neurodevelopment. It was most likely due to a reduced
