Improved Motor Proficiency and Quality of Life in Youth With Prader-Willi Syndrome and Obesity 6 Months After Completing a Parent-Led, Game-Based Intervention.

To determine changes and potential differences in physical activity (PA), gross motor proficiency (MP), and health parameters after a 6-month follow-up (FU) period following participation in a parent-led PA intervention in youth with or without Prader-Willi syndrome (PWS). About 42 youth with PWS and 65 youth without PWS but with obesity (body fat percentage >95th percentile for age and sex), aged 8-16years, participated. The intervention included preplanned PA sessions containing playground and console-based video games scheduled 4 days per week for 24 weeks. Families received training and curriculum materials. PA (accelerometry), MP (Bruininks-Oseretsky Test of MP), and health-related quality of life were obtained before (PRE), after completing the intervention (POST), and at FU. There were no significant changes in PA at any time point. At FU and POST, participants showed higher bilateral coordination (PRE = 9.3 [0.4], POST = 11.7 [0.5], and FU = 11.1 [0.6]); speed and agility (PRE = 9.2 [0.4], POST = 10.8 [0.4], and FU = 11.5 [0.5]); and strength (PRE = 8.0 [0.3], POST = 9.2 [0.3], and FU = 9.2 [0.3]) than at PRE. At FU (80.3 [2.1]) and POST (79.8 [1.7]), youth without PWS showed higher health-related quality of life than PRE (75.0 [1.8]). The improvements in MP and health-related quality of life at FU suggest long-term durability of intervention outcomes.

Pinch grip strength and fine manual control in children with diplegic cerebral palsy: a cross-sectional study

BackgroundIn children with spastic diplegia, efficient use of the upper extremity especially the hands play an important role in participation in daily living. Hands can perform heavy activities and also enable to perform extremely gentle, skillful, and precise activities. Inadequate hand strength and fine motor skills may lead to functional limitations. This study was planned to investigate the pinch grip strength and fine manual control in children with spastic diplegic cerebral palsy and to determine if there is a relation between them. Thirty children with diplegic cerebral palsy and 30 normal developed children from both sexes between 5 and 10 years old were included in this study as diplegic and control groups. For all children, pinch grip strength measured by Baseline Mechanical Pinch Gauge and Bruininks-Oseretsky Test of Motor Proficiency, Second Edition used to evaluate fine manual control.ResultsChildren with diplegic cerebral palsy have significant impairment in the pinch grip strength (tip, tripod, and key) and the fine manual control (fine motor precision and integration) compared to their healthy peers of the same age. There was large positive significant correlation (r > 0.5, p < 0.05) between tip and tripod pinch strength, and fine motor precision and medium positive significant correlation (r = 0.47, p < 0.05) between key pinch and fine motor precision in children with spastic diplegia. Also, there was large positive significant correlation between tip pinch and fine motor integration (r = 0.54, p < 0.05). The correlations are small and medium positive between tripod and key pinch strength, and fine motor integration respectively but they are not statistically significant.ConclusionsPinch grip strength and fine manual skills are affected in children with spastic diplegia. Also, there is a significant correlation between the pinch strength and activities require precise control of the hand.

Effects of Different Multi-Year Physical Exercise Programs on Motor Skills in Preschool Children.

Acquiring optimal motor skills in preschool children presents a key element for proper psychomotor development. Therefore, the aim of this study was to determine gender differences and the effects of a multi-year exercise program on the level of motor skills in 161 preschool children (5–6 yo). Participants were divided into one control and three experimental groups. Motor skills were assessed with the Bruininks-Oseretsky Test of Motor Proficiency (BOT-2). To determine the difference in scores for each BOT-2 test between control and experimental groups, one-way ANOVA was used for girls and boys separately, while two-way ANOVA was used to determine the difference between the genders in the overall BOT-2 score. The results indicate that a 1-year multilateral exercise program has a positive effect on the level of motor skills in preschool children. Interestingly, additional years of participation in exercise programs yielded the maintenance of acquired motor skills level. Additionally, the exercise program affected preschool girls more than boys considering both individual and composite BOT-2 scores. According to the findings of this study, the presented exercise program could have potential benefits on multilateral development of the motor skills in preschool children, which could facilitate the balance of locomotor and manipulative skills. Therefore, the integration of multilateral programs intended for preschool children could be considered for implementation within the kindergarten curriculum.

Evaluation and Cardiac Rehabilitation on a patient with a congenital heart disease

Abstract Funding Acknowledgements Type of funding sources: None. Introduction Severe congenital heart disease (CHD) requiring surgical intervention occurs in 6 of 1000 live-born infants. Substantial improvements in surgical treatment and perioperative care have led to excellent long-term cardiac outcomes for most of these patients and, consequentially, to a significant increase in survival rates. Formal evaluations of preschool, school-aged children and adolescents born with complex CHD demonstrate a pattern of neurodevelopmental sequelae, which may appear alone, or in combination. Purpose F. is a 21 years-old patient with repaired complex transposition of the great arteries with ventricular septal defect, who have already undergone three surgeries: a) an initial palliative surgery (pulmonary artery banding and ductus arteriosus ligation) at the neonatal period; b) a corrective surgery (arterial switch and VSD closure) at the end of the first year of life and c) Pulmonary artery plasty for residual pulmonary stenosis at the age of 16 years-old. Now, he was admitted to our department for urgent wide-complex tachycardia treatment. His initial assessment documented a subjectively impaired motor development, and subsequently, a formal assessment was performed. Methods The Bruininks-Oseretsky Test of Motor Proficiency, second edition (BOT-2) is an individually administrated test that resorts to a series of engaging, goal-directed activities to measure a wide array of motor skills in individuals ages 4 through 21. The BOT-2 uses a subtest and composite structure that highlights motor performance in the broad functional areas of stability, mobility, strength, coordination, and object manipulation. Results Patient"s performance in the four main motor skill areas will be report, namely: Fine Manual Control, Manual Coordination, Body Coordination, and Strength and Agility. Because Fabio completed all four parts of the BOT-2, a comprehensive score from all four areas, the Total Motor Composite, will also be reported. Fabio"s scores were compared to the ones of a control group of age and gender-matched individuals. This Patient started sessions of Cardiac Rehabilitation. The rehabilitation sessions are conducting for 1 hour three times a week for 1 year. This program still in progress, but we speculate that the will improve his motor abilities and developmental skills. Conclusion The risk of a poor developmental outcome varies according to the specific cardiac effect. In addition, there is significant interindividual variation in developmental outcome even among children with the same cardiac defect. Other factors may contribute to neurologic dysfunctions. These factors can be divided into three main categories and time-frames: prenatal, perioperative and post-discharge.

The impact of maternal emotional intelligence on young children’s motor development

ABSTRACT This study examined the relationship between the mother’s emotional intelligence (EI) and children’s motor development. Iranian preschool children (N = 148) in the range of 4–6 years were selected from daycare centres using a multi-stage cluster sampling. The BarOn Emotional Quotient Inventory and Bruininks-Oseretsky Test of Motor Proficiency 2 Short-Form were used to assess EI and child motor development. Results indicated a significant relationship between family income, mother’s education, mother’s EI, and child motor development. Structural equation modelling (SEM) revealed a reliable goodness of fit for the relation between EI and motor development. Also, there was statistically significant association between EI and motor development with an effect size of 45%, thus suggesting that the mother’s EI could predict motor development. Whereas all EI dimensions had some positive influence on the child’s motor development, interpersonal skills highlighted the overall impact. Among the four scales of motor proficiency, the highest effect of EI was with fine-motor skills (55%). Overall, and arguably the most profound finding was that higher EI scores were significantly associated with higher child motor skill scores. In conclusion, these findings support the notion that a mother’s EI could have a significant impact on a child’s motor development.

Neurocognitive function among HIV-infected children on protease inhibitor -based versus non-protease inhibitor based antiretroviral therapy in Uganda: a pilot study

BackgroundHIV infection is associated with significant neurocognitive deficits making maximization of cognitive function among children receiving antiretroviral therapy (ART) a public health imperative. Non-protease inhibitors (non-PIs) achieve higher drug levels in the cerebral spinal fluid (CSF) compared to PIs, potentially leading to better neurocognitive function by reducing CSF viral load and inflammation. ART that maximises children’s neurodevelopment and school achievement could result in improved quality of life and productivity as adults, but little research to date has examined whether non-PI ART is associated with better neurocognitive outcomes. We compared the neurocognitive function between children living with HIV receiving PI-based and non PI-based ART.MethodsWe recruited a consecutive sample of clinically stable Ugandan children living with HIV aged 5–12 years who received PI-based or non PI-based ART for ≥ 1 year (viral load < 1000 copies). Neurocognitive function was assessed using the Kaufman Assessment Battery for Children, the Test of Variables of Attention, and Bruininks-Oseretsky Test of Motor Proficiency. Age-adjusted neurocognitive z-scores for the two groups were compared using linear regression models in STATA version 13. The Hommel’s method was used to adjust for multiple testing.ResultsWe enrolled 76 children living with HIV; 34 on PI ART and 42 on non-PI ART. Mean (±SD) age was greater in the non-PI vs. PI group (9.5 ± 1.9 vs. 8.5 ± 2.0) years (p = 0.03). Children in the non-PI group had lower socioeconomic scores (5.7 ± 3.3 vs. 7.4 ± 2.8, p = 0.02). There was no difference in neurocognitive function between the groups (adjusted p > 0.05) for KABC and TOVA. Children in the PI group had better total BOT scores than their counterparts (46.07 ± 1.40) vs. 40.51 (1.24), p = 0.03).ConclusionsWe detected no difference in neurocognitive function among children on PI and non PI-based ART therapy based on KABC and TOVA tests. Children on PI based ART had better motor function than their counterparts. We recommend a prospective study with a larger sample size.

Handwriting Readiness among Digital Native Kindergarten Students

Aims: Handwriting is an essential life skill, impacted by proficiency in visual-motor integration and fine motor control. The increase in the use of digital technology has changed the way children interact with their environments, and potentially, the development of the important requisite skills for handwriting. This study examined the “handwriting readiness” skills of children born in the digital age. Methods: 219 children in their first year of formal schooling (mean age = 5 years, 10 months), completed the Beery Buktenica Developmental Test of Visual Motor Integration (Beery-VMI) and the Bruininks-Oseretsky Test of Motor Proficiency, Second Edition (BOT-2) Short Form to assess visual motor integration, overall motor proficiency, and fine motor proficiency. Pencil grasp was also observed. Data analysis consisted of descriptive statistics and comparison to established normative data using summary t-tests. Results: Participants met the expected performance level on the Beery-VMI and the manual dexterity subtest of the BOT-2. However, overall motor proficiency on the BOT-2 for our sample was lower than published normative data. Further, 60.3% of participants used static pencil grasps. Conclusions: The findings prompt us to question the potential contribution of digital technology to changes in motor performance among children in the digital age.

Motor and Basic Cognitive Functions in Children with Acute Lymphoblastic Leukemia Undergoing Induction or Consolidation Chemotherapy.

Children with acute leukemia (ALL) often suffer from several disease and treatment related side-effects during treatment. The aim of the present study was to determine the gross and fine motor functioning and basic cognitive performance of children (n = 25) with ALL who were undergoing induction or consolidation chemotherapy and to compare these characteristics to a normative group (n = 21) of age-matched typically developing children. We assessed the children's motor functions with the Bruininks-Oseretsky Test of Motor Proficiency Second Edition-Short Form and the Nine-hole Peg Test, and we used the Modified Mini-Mental State Exam (MMSE) to evaluate their cognitive performance. Compared to the normative group, children with ALL had lower scores on total motor proficiency and sub-tests scores of motor functions (p < .05), and on the Nine-hole Peg Test performance (p < .05); but their cognitive performance on the MMSE was not significantly different. Children with ALL would likely benefit from structured exercise and rehabilitative interventions during chemotherapy to prevent and/or ameliorate ALL-related motor dysfunction. We also suggest that their cognitive functioning should be further investigated with more extensive well-validated neurocognitive tests for children (e.g., the Wechsler intelligence scales).

Long-term outcomes of patients with mucopolysaccharidosis VI treated with galsulfase enzyme replacement therapy since infancy

ObjectiveLong-term outcomes of patients with mucopolysaccharidosis (MPS) VI treated with galsulfase enzyme replacement therapy (ERT) since infancy were evaluated. MethodsThe study was a multicenter, prospective evaluation using data from infants with MPS VI generated during a phase 4 study (ASB-008; Clinicaltrials.govNCT00299000) and clinical data collected ≥5 years after completion of the study. ResultsParents of three subjects from ASB-008 (subjects 1, 2, and 4) provided written informed consent to participate in the follow-up study. One subject was excluded as consent was not provided. Subjects 1, 2, and 4 were aged 0.7, 0.3, and 1.1 years, respectively, at initiation of galsulfase and 10.5, 7.9, and 10.5 years, respectively, at follow-up. All subjects had classical MPS VI based on pre-treatment urinary glycosaminoglycans and the early onset of clinical manifestations. At follow-up, subject 4 had normal stature for age; subjects 1 and 2 had short stature, but height remained around the 90th percentile of growth curves for untreated classical MPS VI. Six-minute walk distance was normal for age/height in subjects 1 (550 m) and 4 (506 m), and reduced for subject 2 (340 m). Subject 2 preserved normal respiratory function, while percent predicted forced vital capacity and forced expiratory volume in 1 s decreased over time in the other subjects. Skeletal dysplasia was already apparent in all subjects at baseline and continued to progress. Cardiac valve disease showed mild progression in subject 1, mild improvement in subject 4, and remained trivial in subject 2. All subjects had considerably reduced pinch and grip strength at follow-up, but functional dexterity was relatively normal for age and there was limited impact on activities of daily living. Bruininks-Oseretsky Test of Motor Proficiency (BOT-2) results showed that subjects 2 and 4 had numerous fine and gross motor competencies. Corneal clouding progressed in all subjects, while progression of hearing impairment was variable. Liver size normalized from baseline in subjects 1 and 4, and remained normal in subject 2. ConclusionVery early and continuous ERT appears to slow down the clinical course of MPS VI, as shown by preservation of endurance, functional dexterity, and several fine and gross motor competencies after 7.7–9.8 years of treatment, and less growth impairment or progression of cardiac disease than could be expected based on the patients' classical phenotype. ERT does not seem to prevent progression of skeletal or eye disease in the long term.

Vestibular, Gaze, and Balance Disorders in Asymptomatic Congenital Cytomegalovirus Infection.

Congenital cytomegalovirus (cCMV) is the leading nongenetic cause of sensorineural hearing loss and developmental disabilities. Because there are limited data from studies of vestibular involvement in select groups of children with cCMV, the true frequency of vestibular disorders in cCMV is likely underestimated. Our objective for this study is to determine the prevalence of vestibular, gaze, and balance disorders in a cohort of children with asymptomatic cCMV. Comprehensive vestibular, gaze, and balance assessments were performed in 40 children with asymptomatic cCMV. The function of semicircular canals of the inner ear and vestibulo-visual tract were assessed by measuring vestibulo-ocular reflex in a computer-driven motorized rotary chair; inner ear saccular function was assessed by using cervical vestibular evoked myogenic potential; gaze stability during head movement was assessed by using clinical dynamic visual acuity, and balance was assessed by using the sensory organization test and the Bruininks-Oseretsky Test of Motor Proficiency, Second Edition. Test results for each variable were compared with those of a control group without cCMV and/or compared to age-matched normative published data. Vestibular disorders were evident in 45% of the cohort on the basis of rotary chair and cervical vestibular evoked myogenic potential testing, suggesting abnormalities in semicircular canals, the utricle and saccule of the inner ear, and vestibulo-visual tracts. Additionally, 46% of the cohort had difficulties maintaining gaze during head movement, and one-third to one-half of the cohort had difficulties maintaining balance. Vestibular, gaze, and balance disorders are highly prevalent in children with asymptomatic cCMV. Systematic screening for vestibular disorders will be used to determine the full clinical impact for the development of effective interventions.

Promoting the development of foundation phase learners in under-resourced environments using Ayres Sensory Integration® principles and custom-designed, low-cost playgrounds

Introduction: Children from under-resourced environments often lack opportunities to engage in sensory experiences that support developmental abilities and scholastic performance. “Back to Urth” playgrounds were designed to address the developmental needs of foundation phase learners in under-resourced communities. A 12-week sensory-motor program, based on Ayres Sensory Integration ® (ASI) principles, was developed, and educators were trained to present this program on a “Back to Urth” playground at a rural school in the Free State. This study aimed to determine the effect of the program, on the development of Grade R and Grade 1 learners. Method: Learners from two comparable, no-fee schools were included in this experimental non-randomised pre-test-post-test control group design study. Learners from one school participated in the sensory-motor program on the “Back to Urth” playground (n=40), and learners from the other school served as the control group (n=41). The effect of the program was measured with the Bruininks-Oseretsky Test of Motor Proficiency 2 nd Edition (Short Form), Revised Ayres-based Clinical Observations, and the Optima School Readiness Assessment. Results: An improvement in scores for both groups, with the experimental group showing statistically greater improvement in their Revised Ayres-based Clinical Observations and Optima School Readiness Assessment total scores were indicated. Conclusion: This research provides evidence that sensory-motor components subserving learning can be improved when learners are exposed to a sensory-motor program designed within the framework of ASI ® , presented by educators on a low cost “Back to Urth” playground.

Longitudinal fixel-based analysis reveals restoration of white matter alterations following balance training in young brain-injured patients

Background and objectivesTraumatic brain injury (TBI) is one of the leading causes of death and disability in children and adolescents. Young TBI patients suffer from gross motor deficits, such as postural control deficits, which can severely compromise their daily life activities. However, little attention has been devoted to uncovering the underlying white matter changes in response to training in TBI. In this study, we used longitudinal fixel-based analysis (FBA), an advanced diffusion imaging analysis technique, to investigate the effect of a balance training program on white matter fibre density and morphology in a group of young TBI patients. MethodsYoung patients with moderate-to-severe TBI (N = 17, 10 females, mean age = 13 ± 3 years) and age-matched controls (N = 17) underwent a home-based balance training program. Diffusion MRI scans together with gross motor assessments, including the gross motor items of the Bruininks-Oseretsky Test of Motor Proficiency, the Activities-Specific Balance Confidence (ABC) Scale, and the Sensory Organization Test (SOT) were administered before and at completion of 8-weeks of training. We used FBA to compare microstructural differences in fibre density (FD), macrostructural (morphological) changes in fibre cross-section (FC), and the combined FD and FC (FDC) metric across the whole brain. We then performed a longitudinal analysis to test whether training restores the white matter in the regions found to be damaged before treatment. ResultsWhole-brain fixel-based analysis revealed lower FD and FC in TBI patients compared to the control group across several commissural tracts, association fibres and projection fibres, with FD reductions of up to 50%. Following training, TBI patients showed a significant interaction effect between Group and Time for the SOT test, as well as significant increases in macrostructural white matter (i.e., FC & FDC) in left sensorimotor tracts. The amount of change in FC and FDC over time was, however, not associated with behavioural changes. DiscussionOur fixel-based findings identified both microstructural and macrostructural abnormalities in young TBI patients. The longitudinal results provide a deeper understanding of the neurobiological mechanisms underlying balance training, which will allow clinicians to make more effective treatment decisions in everyday clinical practice with brain-injured patients.

Tracking postural stability of children and adolescents after a concussion: sport-related versus non-sport-related concussion.

Although postural impairments have long been reported following a concussion in the pediatric population, we still know very little about who is more at risk of presenting those balance problems and how the mechanism of injury (sport vs non-sport) could influence balance problems after concussions. The purpose of this study was to compare balance function in children having sustained a sport-related (SRC) or non-sport-related (NSRC) concussion, to that of children with an orthopedic injury (OI) and to non-injured (NI), over a one-year period. One-hundred and twelve participants were included in this study. Among them, 38 were concussed, with 27 having sustained a SRC; and 11 an NSRC, as well as 38 NI, and 36 OI. Balance function was evaluated at 2 weeks, 3 months, 6 months, and 12 months after a concussion, and at the same time intervals for the control groups. The balance subtest of the Bruininks-Oseretsky Test of Motor Proficiency (BOT2) and Timed Foam Test was used to measure postural instability. Concussion related symptoms were measured by the Post Concussion Symptom Scale (PCSS). There was an improvement in tandem standing on the balance beam (P=.02) and in single-leg standing (SL) on foam surface (P=.02) for all groups over a year. At the 2nd week, NSRC had more postural instability than NI during SL on the balance beam when eyes were closed (P =.01), and performed significantly worse than SRC (P =.01) and NI (P =.01) during SL on the foam surface. NSRC also reported more symptoms than SRC on PCSS (P < 0.001). In the 3rd month, NSRC still had lower performance than SRC in SL on foam surface (P =.01). Children sustaining a concussion outside of a sport seem to have higher levels of postural instability up to 3 months post-injury when compared to those injured in sport.

Assessment of Pediatric Chemotherapy-Induced Peripheral Neuropathy Using a New Patient-Reported Outcome Measure: The P-CIN.

Background: Chemotherapy-induced peripheral neuropathy (CIPN) is commonly experienced by children receiving neurotoxic chemotherapy. No validated pediatric CIPN patient-reported outcome (PRO) measures exist. Purpose: To test sensitivity, internal consistency reliability, content and convergent validity, and feasibility of the Pediatric Chemotherapy-Induced Neuropathy (P-CIN), an electronic PRO measure for assessing CIPN in children who received neurotoxic chemotherapy. Method: Five experts evaluated content validity of the 14-item P-CIN. Children 5 to 17 years old with CIPN (N = 79) completed the P-CIN via tablet computer; a subset (n = 26) also underwent neurological examinations using the Pediatric-Modified Total Neuropathy Score. Following preliminary analyses, one item was deleted and three others modified. The revised P-CIN was retested with patients (n = 6) who also completed the Bruininks-Oseretsky Test of Motor Proficiency motor function assessment. Means, item response ranges, standard deviations, content validity indexes, Cronbach's alphas, and correlation coefficients were calculated. Results: Mean participant age was 11.25 (SD = 4.0) years. Most had acute leukemia (62.5%) and received vincristine (98.7%). Content validity index coefficients ranged from .80 to 1.0 (p = .05). For 9 of 14 items, responses ranged from 0 to 4 or 5; response ranges for toe numbness, pick up a coin, and three of four pain items were 0 to 3. After deleting one item, Cronbach's alpha coefficient was .83. P-CIN scores were strongly associated with Pediatric-Modified Total Neuropathy Score (r = .52, p < .01) and Bruininks-Oseretsky Test of Motor Proficiency (r = -.83, p = .04) scores. Sixty-eight percent of children 6 to 17 years old completed P-CIN independently. Discussion: Preliminary evidence suggests that the 13-item P-CIN is internally consistent, is valid, and can be completed independently by children ≥ 6 years. However, we recommend additional testing.

ASPECTS REGARDING STRENGTH AND AGILITY IN JUNIOR III WATER POLO PLAYERS

The research integrates methods of assessment and analysis of one facet of psychomotricity, namely the strength and agility expressed in a nonspecific (land-based) environment by junior III water polo players. The focus is on the application of two subtests, subtest 1 – Running speed and agility, and subtest 2 – Strength, which are part of the Bruininks-Oseretsky Test of Motor Proficiency, Second Edition. This test battery was applied to high-performance athletes who were in the sights of the national team and were basic members of their club teams. The athletes are born in 1997, play match by match and belong to Steaua School Sports Club 3 (national champion team) and Emil Racoviță Sports College (ranked 3rd in the national championship). The test was conducted on 7 August 2012 in the sports hall of UNEFS Bucharest. The results have shown that, out of the 24 tested athletes, 87% (21 athletes) fall into the average category, and 13% (3 athletes) fall into the above-average category. Mean composite scores are X = 47.25 points for the athletes from Emil Racoviță and X = 53.17 points for those from Steaua. The mean difference is 5.92 points (11.1%) in favour of Steaua athletes. This research has contributed to obtaining, through nonspecific (land-based) means, valuable information on the level of strength and agility of junior III water polo players, which is useful for coaches to introduce technical exercises in their training sessions in order to develop strength and agility under specific competitive conditions and the constant time pressure.

Impact of the sensory environment on balance in children with bilateral cochleovestibular loss

BackgroundThe aim of the present study was to determine the role of auditory and visual sensory input on balance in children with bilateral cochlevestibular loss. The prevalence of vestibular impairment, and specifically bilateral vestibular loss (BVL) in children with sensorineural hearing loss (SNHL) is high and children with profound cochleovestibular loss (SNHL-BVL) have impaired balance (Suarez et al., 2007; Suarez et al., 2019). Given that both hearing and vestibular impairments are often congenital or acquired in early life, it remains difficult to tease out the individual developmental impact of either one on balance and spatial awareness in children who experience both of these sensory deficits. While cochlear implants (CI) can provide or restore access to sound in children with SNHL-BVL, there is currently no vestibular prosthetic available for clinical use in this population. These children may also use their intact sensory inputs (i.e. vision) to a greater extent to support balance. Alternately, restoring or providing access to sound may, on its own, help these children to balance better. We hypothesized that balance in children with SNHL-BVL who use bilateral CIs is: 1) improved in the presence of directional sound and 2) impaired when visual cues are dynamic (moving) rather than static. MethodsBalance was assessed in 18 children with SNHL-BVL and 34 typically developing children with intact vestibular function and normal hearing by performing the Bruininks-Oseretsky Test of Motor Proficiency–2 (BOT-2) balance subtest in a virtual-reality simulator under 4 sensory conditions of graded complexity. Randomized conditions combined 2 auditory (moving directional street sounds vs. directionless static white noise) and 2 visual (dynamic street scene vs. stationary street scene) stimuli designed to recreate a “real-world” busy downtown street. Balance ability in children with SNHL-BVL was also compared with CI on and off. ResultsAs expected and similar to previous work, balance was significantly worse in the children with SNHL-BVL compared to typically developing children in all sensory conditions (p<0.0001). As a group, the mean balance skills of the children with SNHL-BVL were equivalent to that of a 4.4-year-old child despite being much older (mean age =13.8 years). Balance ability improved slightly but significantly when children with SNHL-BVL had access to any sound through their CI (p=0.047) and was positively correlated with duration of implant use (p=0.02). Balance ability did not change further in the presence of moving directional sounds compared to static white noise (p=0.42), or when coupled to a moving visual environment (p=0.32) in children with SNHL-BVL, however opposite to what was hypothesized, in the typically developing group, there was a decrement in performance that occurred in the presence of moving directional sound compared to directionless, static white noise (p=0.02). ConclusionsBalance ability in children with SNHL-BVL who use bilateral CI was, as expected, poorer than their typically developing peers in all sensory conditions but improved slightly when they had access to any sound through their implants, with this benefit increasing as duration of implant use increased. This suggests that providing sound inputs through bilateral CIs positively affects balance in children with SNHL-BVL where vestibular and/or auditory inputs are compromised. This benefit was achieved even with auditory inputs that were devoid of moving directional cues (i.e. directionless static white noise) and is consistent with poor spatial hearing in children using bilateral CI.

An Assessment of the Motor Performance Skills of Children with Autism Spectrum Disorder in the Gulf Region.

This study aims to determine the prevalence, severity, and nature of the motor abnormalities seen in children with autism spectrum disorder (ASD) as well as to elucidate the associated developmental profiles. The short-form of the Bruininks-Oseretsky Test of Motor Proficiency, Second Edition (BOT-2) was used to assess various aspects of the motor performance of 119 children with ASD and 30 typically developing children (age range: 6–12 years) from three Gulf states. The results revealed the high prevalence of motor abnormalities among the ASD group when compared with the normative data derived from the BOT-2 manual as well as with the data concerning the typically developing group. The results also indicated that the motor performance of the children with ASD fell within the below-average range according to the BOT-2 cut-off score. Further, the results suggested that the age variable may influence the overall motor performance of children with ASD, since the children’s motor abnormalities may decrease with maturation. The results concerning the specific motor dysfunction profiles seen in individuals with ASD could help practitioners, parents, and educators to better understand the nature of the motor deficits exhibited by children with ASD, which could assist with the design and implementation of treatment and rehabilitation programs for such children. Overall, motor performance represents an important aspect that should be considered during the clinical evaluation of ASD and that should not be ignored during early interventions.

The validity and reliability of observational assessment tools available to measure fundamental movement skills in school-age children: A systematic review.

Fundamental Movement Skills (FMS) play a critical role in ontogenesis. Many children have insufficient FMS, highlighting the need for universal screening in schools. There are many observational FMS assessment tools, but their psychometric properties are not readily accessible. A systematic review was therefore undertaken to compile evidence of the validity and reliability of observational FMS assessments, to evaluate their suitability for screening. A pre-search of 'fundamental movement skills' OR 'fundamental motor skills' in seven online databases (PubMed, Ovid MEDLINE, Ovid Embase, EBSCO CINAHL, EBSCO SPORTDiscus, Ovid PsycINFO and Web of Science) identified 24 assessment tools for school-aged children that: (i) assess FMS; (ii) measure actual motor competence and (iii) evaluate performance on a standard battery of tasks. Studies were subsequently identified that: (a) used these tools; (b) quantified validity or reliability and (c) sampled school-aged children. Study quality was assessed using COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) checklists. Ninety studies were included following the screening of 1863 articles. Twenty-one assessment tools had limited or no evidence to support their psychometric properties. The Test of Gross Motor Development (TGMD, n = 34) and the Movement Assessment Battery for Children (MABC, n = 37) were the most researched tools. Studies consistently reported good evidence for validity, reliability for the TGMD, whilst only 64% of studies reported similarly promising results for the MABC. Twelve studies found good evidence for the reliability and validity of the Bruininks-Oseretsky Test of Motor Proficiency but poor study quality appeared to inflate results. Considering all assessment tools, those with promising psychometric properties often measured limited aspects of validity/reliability, and/or had limited feasibility for large scale deployment in a school-setting. There is insufficient evidence to justify the use of any observational FMS assessment tools for universal screening in schools, in their current form.

Relationships between gross motor skills, cardiovascular fitness, and visuospatial working memory-related brain activation in 8- to 10-year-old children

Relationships between gross motor skills and cardiovascular fitness with visuospatial working memory (VSWM) in children are hypothesized to be mediated by underlying functional brain mechanisms. Because there is little experimental evidence to support this mechanism, the present study was designed to investigate the relationships of gross motor skills and cardiovascular fitness with VSWM-related brain activation in 8- to 10-year-old children. Functional magnetic resonance imaging data obtained during a VSWM-task were analyzed for 80 children from grades 3 (47.5%) and 4 of 21 primary schools in the Netherlands (51.3% girls). Gross motor skills (Korper Koordinationstest für Kinder and Bruininks-Oseretsky Test of Motor Proficiency - 2nd Edition) and cardiovascular fitness (20-meter Shuttle Run Test) were assessed. VSWM-related brain activation was found in a network involving the angular gyrus, the superior parietal cortex, and the thalamus; deactivation was found in the inferior and middle temporal gyri. Although behavioral results showed significant relations of gross motor skills and cardiovascular fitness with VSWM performance, gross motor skills and cardiovascular fitness were not related to VSWM-related brain activation. Therefore, we could not confirm the hypothesis that brain activation underlies the relationship of gross motor skills and cardiovascular fitness with VSWM performance. Our results suggest that either the effects of physical activity on cognition do not necessarily go via changes in gross motor skills and/or cardiovascular fitness, or that brain activation patterns as measured with the blood-oxygen-level dependent (BOLD) signal may not be the mechanism underlying the relationships of gross motor skills and cardiovascular fitness with VSWM.
