Abstract
Different studies have tried to establish a relationship between dyslexia and the vestibular system function. Subjective Visual Vertical/Horizontal (SVV and SVH) and Video Head Impulse Test (VHIT) are useful for studying the vestibular system and can be easily performed in children. Our aim was to evaluate the vestibular function in dyslexic children by SVV/SVH and VHIT. We enrolled 18 dyslexic children (10M/8F; mean age 10.7 ± 2.3 years; range 7-14 years) and 18 age-matched children with typical development of learning abilities. All children performed VHIT, SVV and SVH. We found normal gain and symmetry of vestibulo-ocular-reflex both in dyslexic and typically developing children. Fifteen out of 18 dyslexic children (83.3%) showed a difference of at least one amongst SVV or SVH. The mean value of SVV was 2.3° and the mean value of SVH was 2.6°. Statistical analysis showed a significant difference between typically developing and dyslexic children for both SVV and SVH. We confirm a relationship between dyslexia and the alteration of SVV and SVH. Our results could be related to the pathogenetic hypothesis of a visual processing impairment related to a dysfunction of the magnocellular pathway or to a general deficit related to a multimodal cortical network.

Abstract
BACKGROUND Otitis media with effusion (OME) frequently leads to vestibular symptoms in children. However, young children face difficulty expressing their symptoms due to their limited language abilities. METHODS The balance of study and patient group evaluated with computer dynamic posturography, single-leg stance test with eyes closed and regular Head Impulse Test. The study group was assessed once again after the insertion of a ventilation tube two months later. RESULTS In the Sensory Organization Test, the scores for conditions 5, 6, and composite equilibrium of the preoperative patient group were notably lower compared with both the control and postoperative patient groups (p < 0.05). Additionally, a significant correlation was found between single-leg stance test with eyes closed results and conditions 5, 6, and composite equilibrium scores. CONCLUSION The impact of OME on the vestibular system is negative. This effect can be objectively assessed using Computer Dynamic Posturography and following tube insertion, there is a notable improvement in vestibular function. Furthermore, the single-leg stance (SLS) test with eyes closed has shown its reliability in assessing balance disorders, notably in children with OME.

Abstract
Tools used for the identification, evaluation, and monitoring of concussion have not been sufficiently studied in youth or real-world settings. Normative and reliability data on sideline concussion assessment measures in the youth athlete population is needed. Pre-season normative data for 515 athletes (93.5% male) aged 5 to 16 on the Standardized Assessment of Concussion (SAC/SAC-Child), modified Balance Errors Scoring System (mBESS), Timed Tandem Gait (TTG), and the King-Devick Test (KDT) are provided. A total of 212 non-injured athletes repeated the measures post-season to assess test-retest reliability. Mean performance on the SAC-C, mBESS, TTG, and KDT tended to improve with age. KDT was the only measure that demonstrated good to excellent stability across age ranges (ICC = 0.758 to 0.941). Concentration was the only SAC/SAC-C subtest to demonstrate moderate test-retest stability (ICC = 0.503 to 0.706). TTG demonstrated moderate to good (ICC = 0.666 to 0.811) reliability. mBESS demonstrated poor to moderate reliability (ICC = -0.309 to 0.651). Commonly used measures of concussion vary regarding test-retest reliability in youth. The data support the use of at least annual sport concussion baseline assessments in the pediatric population to account for the evolution in performance as the child ages. Understanding the variation in the stability and the evolution of baseline performance will enable improved identification of possible injury.

Abstract
This pilot study sought to determine the feasibility of quantifying sensory processing, postural control, motor skill development and participation in daily life in children with idiopathic toe walking (ITW) compared to children without ITW. A nonrandomized, prospective case-control design was employed. Twenty participants were recruited. Computerized weight bearing and postural control data was successfully collected. Differences were found in forefoot/rearfoot weight bearing, balance, sensory-motor abilities and parent reported participation challenges. Sensory processing results were inconclusive. Findings can inform standardized assessment and treatment of ITW.

Abstract
The aim of this research was to study the effect of a horseback-riding programme on postural control in a group of autistic children (ASD). Nine children aged 9 to 12 years participated in this study through a multiple baseline across subjects design. The whole programme took place over nine months. Participants followed a previously developed specific horseback-riding programme, consisting of 45-minute sessions held twice a week for at least three months. To evaluate postural control, the average velocity of the centre of pressure displacement was measured by means of a posturographic platform. Results indicated that this intervention with horses had a positive effect on the postural control in children with ASDs.

Abstract
INTRODUCTION Single-leg stance tests have been widely used to evaluate static balance, like the Modified Flamingo Test. The evaluation of dynamic balance on small support surfaces is the objective of some tests like the Bar Test. RESEARCH QUESTION How is the performance of postural control during the performance of these tests in schoolchildren between 6 and 11 years of age in both sexes? What are the reference values of these tests in this population? METHOD A cross-sectional study in which a total of 282 children. The evaluation included both tests. RESULTS The relative reliability was excellent (Intraclass Correlation Coefficient = 0.84-0.98), and the absolute reliability ranged between 4.5% and 7.1% for coefficient variation and between 0.5 and 1.5 for the standard error of measurement. The average results were 3.8 ± 2.7 floor touches for the Modified Flamingo Test and 5 ± 3.5 m for the Bar Test. The results of both tests improve progressively with the increase of age. DISCUSSION It can be asserted that children of different ages, as well as boys and girls of the same age, perform differently in these tests. Particularly, according to the analysis based on age subgroups, there were greater improvements in the performance of both tests between 8 and 11 years of age. CONCLUSIONS The girls obtained in both tests better results, although between 6 and 7 years of age the differences between sexes are not significant.

Abstract
BACKGROUND While vestibular rehabilitation with virtual reality (VR) is becoming more popular every day, the disadvantages of this method are not yet clear. OBJECTIVE The aim of this study is to examine the effect of the image to be used in vestibular rehabilitation with VR on the systems that provide body posture. METHODS The study was carried out with 36 participants (18 women and 18 men) aged 18 to 30 years. To assess balance control components separately, a sensory organization test was administered to the participants in the presence of stressful and relaxing environment images with VR technology. The State-Trait Anxiety Inventory survey was also used to measure the stress values in the created environments. RESULTS The State-Trait Anxiety Inventory survey revealed that while stressful videos significantly increased stress, relaxing videos reduced stress. Among measurements obtained in the presence of VR, significant decreases were observed mostly in the visual system data. A significant increase in vestibular system data (P=.01) was observed with a decrease in visual system data (P<.001) when the relaxing image was presented. Additionally, there was a significant difference in the somatosensory (P=.001), composite (P=.002), and visual system (P<.001) data in the presence of stressful videos. CONCLUSIONS Although the use of a VR system for vestibular rehabilitation is relatively new, no extant studies have examined how the image type used in VR can affect the integration of visual system data. Therefore, this study is unique in terms of showing the effects of the stress created by the change in the type of the image used in VR. When VR technology is used for therapeutic vestibular rehabilitation for patients whose balance disorder is due to the vestibular system, stress-free videos should be used. However, the use of stressful videos in VR technology will be beneficial in the rehabilitation of those with balance disorders due to the somatosensory system.

Community-based postural control assessment in autistic individuals indicates a similar but delayed trajectory compared to neurotypical individuals. Autism Res 2023; 16:543-557.

Abstract
Autistic individuals exhibit significant sensorimotor differences. Postural stability and control are foundational motor skills for successfully performing many activities of daily living. In neurotypical development, postural stability and control develop throughout childhood and adolescence. In autistic development, previous studies have focused primarily on individual age groups (e.g., childhood, adolescence, adulthood) or only controlled for age using age-matching. Here, we examined the age trajectories of postural stability and control in autism from childhood through adolescents using standardized clinical assessments. In study 1, we tested the postural stability of autistic (n = 27) and neurotypical (n = 41) children, adolescents, and young adults aged 7-20 years during quiet standing on a force plate in three visual conditions: eyes open (EO), eyes closed (EC), and eyes open with the head in a translucent dome (Dome). Postural sway variability decreased as age increased for both groups, but autistic participants showed greater variability than neurotypical participants across age. In study 2, we tested autistic (n = 21) and neurotypical (n = 32) children and adolescents aged 7-16 years during a dynamic postural control task with nine targets. Postural control efficiency increased as age increased for both groups, but autistic participants were less efficient compared to neurotypical participants across age. Together, these results indicate that autistic individuals have a similar age trajectory for postural stability and control compared to neurotypical individuals, but have lower postural stability and control overall.

Abstract
With this study, it was aimed to examine the effect of coordination-based movement education model on the development of balance in 5-year-old children. The research was designed with a control group pre-test post-test design, which is one of the quasi-experimental research models. The research group consists of a total of 42 (n = 20 experimental n = 22 control) 5-year-old children formed by using the convenient sampling method, which is one of the purposeful sampling methods. Each participant's age, body weight, body length and lower extremity limb lengths were measured. As a data collection tool and used the three-part Y Balance Test (YBT) platform, which was previously stated to have high reliability (ICC = 0.85-0.93). Reach distances of the participants were measured in three directions, anterior posteromedial and posterolateral. YBT scores were determined by calculating the average and normalized values for lower extremity limb length for each reach direction of the obtained scores, and composite YBT scores were determined by taking the averages of anterior, posteromedial and posterolateral reach distance scores. In order to determine whether the collected data are suitable for normal distribution, Levene test was applied first and it was determined that p > 0.05 for all parameters as a result of the test. Independent sample T-test from parametric tests was used to determine the differences between groups. Paired-group T-test was used to determine within-group differences. According to the results of the research, it was found that the balance motor capacity levels between the experimental and control groups did not differ significantly compared to the pre-test, but there was a significant difference in all reach directions scores in favor of the post-test and experimental group compared to the control group and the pre-test. When the results of the right and left lower extremity ANT, PM, PL and Composite reach distances were examined according to gender, although there was no statistically significant difference, when the averages were considered, it was seen that all parameters were in favor of girls (p > 0.05). As a result, it was concluded that coordination-based movement education model had a positive effect on the balance motor capacities of 5-year-old children.

Abstract
PURPOSE Balance performance can be measured with a computerized dynamic posturography (CDP). Frequently used CDP protocols include the sensory organization test (SOT), motor control test (MCT) and adaptation test (ADT). The primary aim of this study was to produce normative data using the Bertec® Balance Advantage CDP on a cohort of healthy adults aged 20-79 years for the SOT, MCT and ADT. The secondary aim was to determine age- and gender-related differences. METHODS The study population of 120 participants were divided into age groups of 20-29, 30-39 years, etc., with an equal number of men and women in each group. Using the Bertec® CDP, the SOT, MCT and ADT protocols were performed. RESULTS SOT found that the 70-79 age group and men scored lower equilibrium scores (ES) on SOT4, and SOT6. Women had higher ES on SOT1. For the MCT, backward translation. latencies were higher for the 60 s and 70 s age groups. The 60 s age group had higher forward translation latencies. Women had lower latencies on all MCTs. For the ADT toes up test, the 70-79 age group scored higher sway energy. On the toes down test, higher sway energy was registered for the 50-79 age groups. Women had lower sway energy for both ADT's. CONCLUSION We have produced normative data for healthy adults aged 20-79 years for the SOT, MCT and ADT protocols using the Bertec® Balance Advantage CDP. Balance performance differences might be due to decline in visual acuity, presbyvestibulopathy and differences in body composition.

Abstract
Objectives: Balance is a crucial ability of early age, but there is conflicting evidence with regard to age and gender differences in preschool children's balance ability. Additionally, there are several tools available to measure balance, yet, wide variation in their use has restricted the capacity to synthesize the reference values. Therefore, the primary purpose of this study was to investigate the balance ability of preschool-aged children and determine how it is moderated by age and gender. The analysis pertained to determining whether different testing methods affect the results of static or dynamic balancing ability to provide a basis for normative balance ability data for healthy boys and girls between 3 and 6 years of age. Method: Six hundred and nineteen preschool children (296 boys and 323 girls) aged 3-6 years participated in the study. The static balance (SB) was assessed with children standing on one leg (OST) and in a tandem stance (TS) with respect to time. The balance beam test (BBT) and functional reach test (FRT) were used to evaluate dynamic balance (DB) by measuring the time spent and the distance reached, respectively. Result: The results revealed significant differences in OST with respect to gender (η2 = 0.037, p < 0.001), TS (η2 = 0.026, p < 0.001) and FRT (η2 = 0.016, p = 0.002); the girls performed better than boys on most balance tests except on BBT (η2 = 0.000, p = 0.596). Age had positive effects on the static and dynamic balance performance on the OST (η2 = 0.336, p < 0.001), TS (η2 = 0.205, p < 0.001), BBT (η2 = 0.367, p < 0.001) and FRT (η2 = 0.392, p < 0.001). Older children performed better than their younger counterparts. No significant interactions between age groups and sex were found. Conclusion: This study revealed that static and dynamic balance stability in preschool-aged children was affected by gender and age. Gender dimorphism is present in preschool children, older girls displayed better postural stability than boys, and balance performance improved with age. In addition, the study provides age- and gender-specific balance performance reference values for preschool children across multiple methods, which can be used to monitor static and dynamic balance development.

[PMID: 36036296 DOI: 10.1007/s10072-022-06355-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/28/2022] [Accepted: 08/16/2022] [Indexed: 10/15/2022]
Abstract
OBJECTIVE The purpose of this study was to investigate the age and attentional focus instruction effects on the postural and supra-postural tasks among older adults with mild cognitive impairments. METHOD Forty healthy adults (mean age of 48.01 ± 5.45 years) and 40 older adults with mild cognitive impairments (mean age of 69.87 ± 4.28 years) were selected as participants. They were randomly divided into eight groups receiving internal and external attentional focus instructions for postural and supra-postural tasks. The postural status was evaluated by measuring the COP sway velocity with the Master Balance System. RESULTS The results showed that in both phases of acquisition and retention, the main effect of the attentional focus type was significant (P < 0.05). The group's postural control with external attentional instructions was better than the group's postural control with internal attentional instructions. Furthermore, the CI elderly gained benefit from the guidelines of attentional focus. Results showed that the task type was not significant in the acquisition phase. However, in the retention phase, the main effect of the attentional focus type was significant. The groups' postural function with the supra-postural task was better than the groups with the postural task. Furthermore, the older adults showed a better postural function in the supra-postural task than in the postural task. CONCLUSIONS Our results showed that the ability to allocate resources of attention may decrease with CI. These findings suggest that considering the effect of the supra-postural tasks' manipulation on postural control, it is possible to improve balance by designing training programs for directing supra-postural tasks. The findings of the present study can be a guide for educators and therapists. They can increase the balance of the patients by considering the dysfunction and the type of attentional guidelines to prevent them from falling and performing a dual task.

Effects of age and surface instability on the control of the center of mass. Hum Mov Sci 2022; 82:102930. [PMID: 35123153 DOI: 10.1016/j.humov.2022.102930] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/10/2021] [Revised: 01/17/2022] [Accepted: 01/19/2022] [Indexed: 11/22/2022]
Abstract
During standing, posture can be controlled by accelerating the Center of Mass (CoM) through shifting the center of pressure (CoP) within the base of support by applying ankle moments ("CoP mechanism"), or through the "counter-rotation mechanism", i.e., changing the angular momentum of segments around the CoM to change the direction of the ground reaction force. Postural control develops over the lifespan; at both the beginning and the end of the lifespan adequate postural control appears more challenging. In this study, we aimed to assess mediolateral balance performance and the related use of the postural control mechanisms in children, older adults and younger adults when standing on different (unstable) surfaces. Sixteen pre-pubertal children (6-9y), 17 younger adults (18-24y) and eight older adults (65-80y) performed bipedal upright standing trials of 16 s on a rigid surface and on three balance boards that could freely move in the frontal plane, varying in height (15-19 cm) of the surface of the board above the point of contact with the floor. Full body kinematics (16 segments, 48 markers, using SIMI 3D-motion analysis system (GmbH) and DeepLabCut and Anipose) were retrieved. Performance related outcome measures, i.e., the number of trials with balance loss and the Root Mean Square (RMS) of the time series of the CoM acceleration, the contributions of the CoP mechanism and the counter-rotation mechanism to the CoM acceleration in the frontal plane and selected kinematic measures, i.e. the orientation of the board and the head and the Mean Power Frequency (MPF) of the balance board orientation and the CoM acceleration were determined. Balance loss only occurred when standing on the highest balance board, twice in one older adult once in one younger adult. In children and older adults, the RMS of the CoM accelerations were larger, corresponding to poorer balance performance. Across age groups and conditions, the contribution of the CoP mechanism to the total CoM acceleration was much larger than that of the counter-rotation mechanisms, ranging from 94% to 113% vs 23% to 38% (with totals higher than 100% indicating opposite effects of both mechanisms). Deviations in head orientation were small compared to deviations in balance board orientation. We suggest that the CoP mechanism is dominant, since the counter-rotation mechanism would conflict with stabilizing the orientation of the head in space.

[PMID: 32927763 PMCID: PMC7565156 DOI: 10.3390/jcm9092919] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/08/2020] [Revised: 09/08/2020] [Accepted: 09/09/2020] [Indexed: 12/24/2022] Open
Abstract
Background: This study aims to analyze the effect of physical activity practice on the postural control state of school children. If such an effect was detected, the second aim of the study was to identify which specific capacities of postural control benefited the most from physical activity. Methods: A cross-sectional study was performed using a convenience sample of 118 healthy children (54 girls) with a mean age of 10.3 ± 1.2 years. Their weight and height were measured. The accelerometric assessment of balance included four different tests in static balance and walking. Results: Physical activity habit prevalence was 38.9% in girls and 60.9% in boys, and its frequency was 2.3 days per week in girls and 2.8 days in boys. The active children obtained lower accelerations, but the active and sedentary girls showed lower accelerometric values than the active boys. The logistic regression analysis demonstrated the influence of sex on the accelerations of the body (p < 0.001), regardless of the habit of physical activity. Conclusions: Active children have better postural control than sedentary children, although sedentary girls have better balance than active boys. Therefore, physical activity practice seems to favor a more efficient development of postural control, but it cannot level or reverse the effect of the neurophysiological factors that are conditioned by sex.
