Beerse M, Larsen K, Alam T, Talboy A, Wu J. Joint kinematics and SPM analysis of gait in children with and without Down syndrome. Hum Mov Sci 2024; 95:103213. [PMID: 38520896 DOI: 10.1016/j.humov.2024.103213] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/06/2023] [Revised: 01/26/2024] [Accepted: 03/18/2024] [Indexed: 03/25/2024]
Abstract
BACKGROUND Individuals with Down syndrome (DS) walk with altered gait patterns compared to their typically developing (TD) peers. While walking at faster speeds and with external ankle load, preadolescents with DS demonstrate spatiotemporal and kinetic improvements. However, evidence of joint kinematic adjustments is unknown, which is imperative for targeted rehabilitation design. RESEARCH QUESTION How does increasing walking speed and adding ankle load affect the joint kinematics of children with and without DS during overground walking? METHODS In this cross-sectional observational study, thirteen children with DS aged 7-11 years and thirteen age- and sex-matched TD children completed overground walking trials. There were two speed conditions: normal speed and fast speed (as fast as possible without running). There were two load conditions: no load and ankle load (2% of body mass added bilaterally above the ankle). A motion capture system was used to register the ankle, knee, and hip joint angles in the sagittal plane. Peak flexion/extension angles, range of motion, and timing of peak angles were identified. In addition, statistical parametric mapping (SPM) was conducted to evaluate the trajectory of the ankle, knee, and hip joint angles across the entire gait cycle. RESULTS AND SIGNIFICANCE SPM analysis revealed the DS group walked with greater ankle, knee, and hip flexion compared to the TD group for most of the gait cycle, regardless of condition. Further, increasing walking speed led to improved ankle joint kinematics in both groups by shifting peak plantarflexion closer to toe-off. However, knee extension during stance was challenged in the DS group. Adding ankle load improved hip and knee kinematics in both groups but reduced peak plantarflexion around toe-off. The kinematic adjustments in the DS group suggest specific motor strategies to accommodate their neuromuscular deficits, which can provide a foundation to design targeted gait-based interventions for children with DS.

González-Domenech PJ, Gurpegui M, González-Domenech CM, Gómez-González S, Rustarazo A, Ruiz-Nieto V, Carretero MD, Gutiérrez-Rojas L. Prader-Willi syndrome in a large sample from Spain: general features, obesity and regular use of psychotropic medication. JOURNAL OF INTELLECTUAL DISABILITY RESEARCH : JIDR 2024; 68:446-463. [PMID: 38246690 DOI: 10.1111/jir.13123] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/04/2022] [Revised: 12/22/2023] [Accepted: 12/27/2023] [Indexed: 01/23/2024]
Abstract
BACKGROUND Prader-Willi syndrome (PWS), a genetically determined disorder, the most frequent cause of early onset obesity, is associated with physical and cognitive dysfunctions and behavioural disturbances; these disturbances are frequently treated with psychotropic medication. The aim of this cross-sectional study was to describe the characteristics of the first large national sample of persons with PWS in Spain and analyse the relationships of those characteristics with key demographic and clinical factors, particularly with obesity and the regular use of psychotropic medication. METHODS Participants were recruited among all members of the Spanish Prader-Willi Association who agreed to take part in the study and fulfilled its inclusion criteria. Family and patient demographic features, family size and birth order, intelligence quotient (IQ), anthropometric measures, lifestyle habits, behavioural disturbances (with the Aberrant Behavior Checklist) and clinical data, as well as use of psychotropic drugs and their side effects (with the UKU scale), were collected in genetically confirmed cases of PWS. Bivariate and logistic regression analyses were used for determining the associations of demographic and clinical factors with both obesity and the regular use of psychotropic medication. RESULTS The cohort included 177 participants (aged 6-48 years), that is, 90 (50.8%) males and 87 (49.2%) females. Behavioural disturbances were present in a range of 75% to 93% of participants; psychotropic medication was prescribed to 81 (45.8%) of them. Number of siblings showed a direct correlation with IQ, especially among males, and inappropriate speech was more intense in only-child females. Obesity was, in parallel, strongly associated with ascending age and with not being currently under growth hormone (GH) treatment. Participants taking any psychotropic medication were characterised by more frequent age ≥30 years, high level of hyperactivity and a psychiatric diagnosis. CONCLUSIONS Characterisation of persons with PWS in Spain confirms their physical and behavioural phenotype and supports the long-term application of GH therapy and the rational use of psychotropic medication.

Abstract
BACKGROUND Living with a child with Down syndrome (DS) influences the entire family, including caregivers. AIMS This study examined positive and negative caregiver feelings about parenting youth with DS and to what extent children's demographic, cognitive, behavioral characteristics, and co-occurring medical conditions are associated with those parental feelings. Specifically, the mediatory role of child behavioral challenges on the relationship between child executive functioning (EF) and parent feelings about parenting a child with DS was examined in a mediation analysis model. METHODS AND PROCEDURES Parents of 113 youth with DS aged 6 to 17 year rated their positive and negative feelings about parenting, and their child's behavioral challenges and EF. OUTCOMES AND RESULTS Externalizing and Internalizing behavioral challenges and emotional and behavioral regulations of EF were significantly associated with positive and negative parent feelings. Child behavioral challenges fully mediated the relationship between child EF and caregiver feelings about parenting, after controlling for identified covariates of child demographics. CONCLUSIONS AND IMPLICATIONS Findings have implications for understanding the role of EF, through its impact on behavioral challenges, on the feelings of caregivers about parenting a child with DS. These findings play a role in understanding outcomes of interventions targeted at EF and behavioral challenges, in the context of other child variables.

Abstract
This study explores sex-differences in (a) rates and profiles of autism symptoms as well as in (b) the contribution of intellectual quotient (IQ) to autism symptom presentation in Down syndrome (DS). Participants were 40 males and 38 females with DS, aged 6 to 23 years. Autism symptoms were rated through the Autism Diagnostic Observation Schedule-Second Edition (ADOS-2). Results show no sex differences in the ADOS-2 Calibrated Severity Scores (CSS). However, only females with DS who are classified as DS-Only have higher scores on verbal IQ than those classified as DS + autism. Furthermore, associations between IQ and all CSSs are found for females, but not for males. Findings suggest that verbal cognition may play differential roles for females and males with DS.

Abstract
Individuals with Down syndrome (DS) experience a range of medical and neurodevelopmental conditions, necessitating systematic study of their occurrence and impact on neurodevelopmental outcomes. We describe the prevalence and relationships of medical, neurodevelopmental (ND), and mental health (MH) conditions in children with DS. We created a prospective clinical database of individuals with DS, integrated into the workflow of a specialty Down Syndrome Program at a specialty pediatric referral hospital. Conditions were collected through caregiver- and clinician report at clinical visits (N = 599). We calculated frequencies of medical, ND, and MH conditions and then assessed the relationship between medical, ND, and MH conditions using frequencies and comparative statistics. The most frequent co-occurring conditions were vision (72.5%), ear/hearing (71.0%), gastrointestinal (61.3%), respiratory (45.6%), and feeding (33.6%) problems, with variation in frequency by age. ND and MH conditions were reported in one quarter, most commonly autism spectrum disorder and attention-deficit/hyperactivity disorder. Those with ND and MH conditions had greater frequency of medical conditions, with highest rates of vision, ear/hearing, and gastrointestinal issues, and CHD. Systematically collected clinical data in a large cohort of children with DS reveals high prevalence of several co-occurring medical, ND, and MH conditions. Clinical care requires an understanding of the complex relationship between medical conditions and neurodevelopment.

Abstract
CASE Maria is an 8-year-old girl with Down syndrome, described by her mother as an affectionate and social child, who was referred to developmental-behavioral pediatrics by her pediatrician because of increasing aggressive behaviors and inattention.Maria was 5 pounds at birth, delivered full-term by cesarean section, and hospitalized for 1 month after delivery because of feeding issues that required a nasogastric (NG) tube. Maternal age was 24 years, pregnancy was uncomplicated, and there were no reported prenatal exposures to substances. Additional medical history includes corrective cardiac surgery at age 11 months, mild-to-moderate hearing loss in 1 ear, and myopia.At the time of Maria's presentation to developmental-behavioral pediatrics, she was in third grade and had an IEP with placement in a substantially separate multigrade classroom and inclusion for special classes such as music and art. She had multiple academic goals and accommodations for behaviors such as eloping from class, shoving, and growling at adults; communication Picture Exchange Communication System (PECS); and extended time to complete assignments. Previously, she had attended an inclusion setting with a 1:1 aide. Maria is followed annually at a specialty clinic that focuses on the health needs of children with Down syndrome. At home, Maria's parents speak primarily Spanish, while her 2 older brothers speak primarily English. Maria has been using 3-word phrases since she was 6 years old and understands some American Sign Language. She also uses a PECS book for communication.During the visit, Maria was notably fidgety, frequently interrupted the parent interview despite having toys to play with, and became aggressive-hitting, kicking, pushing, and shoving-when she did not want to comply with directives. She used mostly single words and a variety of gestures to communicate. Both the parent-completed and teacher-completed Conners-3 (Long Version) produced elevated T-scores (>70) in the domains of inattention, hyperactivity/impulsivity, defiance/aggression, peer relations, Global Index scale, DSM-5 Hyperactive/Impulsive symptom scale, and DSM-5 Conduct Disorder symptom scale. The teacher endorsed full criteria for attention-deficit/hyperactivity disorder, consistent with combined presentation, and the parent endorsed symptoms in a similar pattern. Methylphenidate (2.5 mg) was trialed but tolerated poorly when it was titrated to 5 mg. Maria's mother reported that Maria's focus was somewhat better, but she was easily brought to tears and "not herself."What would be the next steps in Maria's evaluation/treatment? Could there be reasons for her worsening behavior other than a primary attention disorder?

Abstract
BACKGROUND People with intellectual disabilities are more likely to experience sleep problems, which can affect quality of life, physical health, mental health and well-being. METHODS An integrative literature review was conducted to investigate what is known about behavioural sleep disturbances in people with an intellectual disability. The search used the following databases: Scopus, PsycInfo and Cinahl, to find papers published since 2015. RESULTS Within intellectual disability research, sleep appears as a common issue due to its high prevalence, negative relationships with an individual's physical and mental health, their quality of life, and impact of sleep problems on family or carers. The growing evidence base appears to support the use of behavioural, lifestyle and pharmacological interventions to improve sleep in people with an intellectual disability. CONCLUSION A wide array of literature provides evidence that people with intellectual disabilities are affected by and need support with their sleep.

Abstract
Children and adolescents with neurodevelopmental disorders generally show adaptive, cognitive and motor skills impairments associated with behavioral problems, i.e., alterations in attention, anxiety and stress regulation, emotional and social relationships, which strongly limit their quality of life. This narrative review aims at providing a critical overview of the current knowledge in the field of serious games (SGs), known as digital instructional interactive videogames, applied to neurodevelopmental disorders. Indeed, a growing number of studies is drawing attention to SGs as innovative and promising interventions in managing neurobehavioral and cognitive disturbs in children with neurodevelopmental disorders. Accordingly, we provide a literature overview of the current evidence regarding the actions and the effects of SGs. In addition, we describe neurobehavioral alterations occurring in some specific neurodevelopmental disorders for which a possible therapeutic use of SGs has been suggested. Finally, we discuss findings obtained in clinical trials using SGs as digital therapeutics in neurodevelopment disorders and suggest new directions and hypotheses for future studies to bridge the gaps between clinical research and clinical practice.

Abstract
Behavioral aspects of organized sports activity for pediatric athletes are considered in a world consumed with winning at all costs. In the first part of this treatise, we deal with a number of themes faced by our children in their sports play. These concepts include the lure of sports, sports attrition, the mental health of pediatric athletes (i.e., effects of stress, anxiety, depression, suicide in athletes, ADHD and stimulants, coping with injuries, drug use, and eating disorders), violence in sports (i.e., concepts of the abused athlete including sexual abuse), dealing with supervisors (i.e., coaches, parents), peers, the talented athlete, early sports specialization and sports clubs. In the second part of this discussion, we cover ergolytic agents consumed by young athletes in attempts to win at all costs. Sports doping agents covered include anabolic steroids (anabolic-androgenic steroids or AAS), androstenedione, dehydroepiandrostenedione (DHEA), human growth hormone (hGH; also its human recombinant homologue: rhGH), clenbuterol, creatine, gamma hydroxybutyrate (GHB), amphetamines, caffeine and ephedrine. Also considered are blood doping that includes erythropoietin (EPO) and concepts of gene doping. In the last section of this discussion, we look at disabled pediatric athletes that include such concepts as athletes with spinal cord injuries (SCIs), myelomeningocele, cerebral palsy, wheelchair athletes, and amputee athletes; also covered are pediatric athletes with visual impairment, deafness, and those with intellectual disability including Down syndrome. In addition, concepts of autonomic dysreflexia, boosting and atlantoaxial instability are emphasized. We conclude that clinicians and society should protect our precious pediatric athletes who face many challenges in their involvement with organized sports in a world obsessed with winning. There is much we can do to help our young athletes find benefit from sports play while avoiding or blunting negative consequences of organized sport activities.

Abstract
Objective To develop standardization for nomenclature, diagnostic work up and diagnostic criteria for cases of neurocognitive regression in Down syndrome. Background There are no consensus criteria for the evaluation or diagnosis of neurocognitive regression in persons with Down syndrome. As such, previously published data on this condition is relegated to smaller case series with heterogenous data sets. Lack of standardized assessment tools has slowed research in this clinical area. Methods The authors performed a two-round traditional Delphi method survey of an international group of clinicians with experience in treating Down syndrome to develop a standardized approach to clinical care and research in this area. Thirty-eight potential panelists who had either previously published on neurocognitive regression in Down syndrome or were involved in national or international working groups on this condition were invited to participate. In total, 27 panelists (71%) represented nine medical specialties and six different countries reached agreement on preliminary standards in this disease area. Moderators developed a proposed nomenclature, diagnostic work up and diagnostic criteria based on previously published reports of regression in persons with Down syndrome. Results During the first round of survey, agreement on nomenclature for the condition was reached with 78% of panelists agreeing to use the term Down Syndrome Regression Disorder (DSRD). Agreement on diagnostic work up and diagnostic criteria was not reach on the first round due to low agreement amongst panelists with regards to the need for neurodiagnostic testing. Following incorporation of panelist feedback, diagnostic criteria were agreed upon (96% agreement on neuroimaging, 100% agreement on bloodwork, 88% agreement on lumbar puncture, 100% agreement on urine studies, and 96% agreement on "other" studies) as were diagnostic criteria (96% agreement). Conclusions The authors present international consensus agreement on the nomenclature, diagnostic work up, and diagnostic criteria for DSRD, providing an initial practical framework that can advance both research and clinical practices for this condition.
