Sensory integration therapies for children with developmental and behavioral disorders

Inter-hemispheric somatosensory coherence and parental stress in hypersensitivity at 8 months old: An electroencephalography study

OBJECTIVE

Infant hypersensitivity affects daily challenges and parental stress. Although the crucial role of tactile sensation in infants' brain function has been highlighted, hypersensitive infants and their families lack support. Electroencephalography may be useful for understanding hypersensitivity traits. We investigated the relationship between infant perceptual hypersensitivity and parental stress, somatosensory-evoked potential (SEP), and magnitude-squared coherence (MSC) in the general population.

METHODS

Infants aged 8 months (n = 63) were evaluated for hypersensitivity and parental stress using a questionnaire and for cortical activity using electroencephalography. Vibration stimuli were applied to the infant's left foot. SEP components that peaked around 150 ms (N2) and at 200 ms (P2) after stimulus onset were evaluated by amplitude and latency at the midline electrode (Cz) and MSC between the midline electrodes (C3-C4).

RESULTS

Parental stress was associated with infant hypersensitivity. The latency of Cz was delayed, and C3-C4 delta MSC was high in infants with hypersensitivity.

CONCLUSIONS

Increasing inter-hemispheric MSC synchrony in the stimulated condition in infants with hypersensitivity suggested atypical somatosensory cortical function.

SIGNIFICANCE

These findings contribute to identifying, understanding the mechanisms of, and developing effective coping strategies for early-stage hypersensitivity.

The Effect of Early Pediatric Rehabilitation in an Infant With Vitamin B12 Deficiency Associated With Developmental Delay: A Case Report

Developmental delay is a multifaceted condition that can hamper a child's ability to attain developmental benchmarks within expected timelines. Vitamin B12 deficiency has been identified as a potentially reversible causative factor and is critical to neurological function, influencing myelination and nerve conduction. Insufficiency during critical developmental stages can lead to motor, cognitive, and language delays. Physiotherapy interventions have been found effective in addressing motor delays associated with both developmental delay and B12 deficiency. Early intervention programs that focus on motor skill development, sensory integration, and adaptive equipment use are among the interventions that physiotherapists provide. Collaboration with multidisciplinary teams allows physiotherapists to manage B12 deficiency effectively and provide rehabilitative strategies aimed at maximizing motor function and overall development for long-term health. Early identification and intervention in children with developmental delays is crucial, especially in cases related to vitamin B12 deficiency. Physiotherapy is a critical aspect of addressing motor delays associated with developmental delay and B12 deficiency. By providing early interventions, physiotherapists can help children attain their full potential and attain developmental milestones. In conclusion, this highlights the significance of early identification and intervention in children with developmental delay, especially those with vitamin B12 deficiency, for optimal long-term health.

An investigation of sensory processing skills in toddlers with joint hypermobility

BACKGROUND

Children with Generalized Joint Hypermobility (GJH) may have a motor developmental delay in the early period and subluxation, fatigue, autonomic dysfunction, and pain arising from ligaments and other soft tissues in advanced ages. Additionally, there is a loss of proprioceptive sensation in children and adults with GJH.

AIMS

This study aimed to evaluate sensory processing skills in toddlers with GJH.

STUDY DESIGN

A cross-sectional study.

SUBJECTS

Fifty-eight children aged between 12 and 14 months were included in the study. These children were divided into two groups: with and without GJH (31 with GJH and 27 without GJH).

OUTCOME MEASURES

The sensory processing skills of the children in the study were evaluated with the Test of Sensory Functions in Infants (TSFI).

RESULTS

The scores in the subtests of TSFI in response to tactile deep pressure, adaptive motor functions, visual-tactile integration, and response to vestibular stimuli were higher in favor of children without GJH (p < 0.05). The total TSFI score was higher in the group without GJH (p < 0.05).

CONCLUSIONS

Sensory processing problems were found in toddlers with GJH. Sensory motor development should be evaluated in children with GJH, and an appropriate early intervention program should be planned.

Assessment of Multisensory Sensitivity May Assist With the Management of Children With Chronic Pain

Chronic pain is a significant problem in adults; however, it can also be challenging to evaluate and manage effectively in pediatric and adolescent populations. Many theories implicate different factors that cause pain to become chronic, more severe, or more detrimental to function. There is emerging evidence for the role of generalized multisensory sensitivity (MSS) as a contributing factor to chronic pain in the adult population; however, similar evidence in the pediatric literature is lacking. Thus, the purpose of this case series is to highlight the clinical use of MSS assessment in children and adolescents with chronic pain to better phenotype and provide targeted treatment. In this case series, we reviewed 5 patients between 12 and 16 years of age who received evaluation for multifocal, chronic pain in a multidisciplinary pain clinic. During the initial consultations, we reviewed the medical records, completed a full medical history, performed a physical examination, and assessed for MSS. It is theorized that MSS is a marker of increased central nervous system sensitivity to sensory input that may also impact pain processing and, potentially, a poorer prognosis. Four patients with MSS appeared to benefit from the inclusion of additional therapies, such as desensitization and occupational therapy, which was in contrast to the patient without notable MSS. Based on anecdotal observation of these 5 cases, increased sensory hypersensitivity is 1 additional factor that may be used to delineate possible neurobiological mechanisms and aid in the treatment decision-making for this challenging population.

Diffusion tensor imaging of the brain in children with sensory processing disorder: A review

Sensory processing disorder (SPD) is a clinical condition characterized by difficulties in the neurological processes of registering, discriminating, organizing, and responding to various sensory sensations. This study aimed to review the association between impaired white matter (WM) tract structure and neurofunctional deficits in children with SPD using diffusion tensor imaging (DTI). A comprehensive literature search was conducted using the online databases Google Scholar and PubMed (from 2010 to July 2023), resulting in the selection of nine relevant studies. Findings revealed that the splenium of the corpus callosum (SCC), superior longitudinal fasciculus (SLF), posterior corona radiata (PCR), and posterior thalamic radiation (PTR) exhibited reduced microstructural integrity, strongly associated with SPD. Specifically, auditory over-responsivity, a subtype of SPD, was linked to impaired integrity of the PCR, PTR, anterior corona radiata, and SLF. Tactile over-responsivity (TOR) was correlated with markers of decreased integrity in the SCC, superior corona radiata, and left PTR. Among the DTI parameters, decreased fractional anisotropy (FA) emerged as the most reliable factor for identifying SPD, followed by increased radial diffusivity (RD) and mean diffusivity (MD). Notably, significant correlations were observed between with auditory over-responsivity and TOR with the DTI parameters (positive for FA and negative for RD and MD). Overall, this review confirms the impaired integrity of specific WM tracts in children with SPD and establishes correlations between DTI parameters and neurobehavioral deficits associated with the disorder. The insights gained from this review contribute to a better understanding of SPD and hold clinical implications for its diagnosis and treatment.

A Case Report of Pediatric Rehabilitation for Hypoxic Ischemic Encephalopathy Associated With Global Developmental Delay

Hypoxic ischemic encephalopathy (HIE) is a critical condition affecting neonates due to oxygen deprivation and insufficient flow of blood to the brain. It is associated with high neonatal mortality and the risk of developmental psychomotor disorders, including cerebral palsy. The global epidemiology of HIE reveals significant disparities, with more advanced healthcare systems reporting lower incidence rates. The aim of the study is to contribute to the understanding of effective rehabilitation strategies for children with HIE and global developmental delay (GDD), with the goal of improving outcomes and quality of life for these individuals. This case report focuses on an 11-month-old male child with a history of perinatal HIE, highlighting the developmental challenges and interventions undertaken. The child showed delayed gross and fine motor development, sensory awareness deficits, and postural coordination issues. A comprehensive physiotherapy intervention plan was implemented, resulting in significant improvements in post-treatment outcome measures. This case highlights the importance of early and holistic physiotherapy interventions in addressing HIE patients' developmental delays and improving their quality of life.

Sensory Symptoms and Signs of Hyperarousal in Individuals with Fragile X Syndrome: Findings from the FORWARD Registry and Database Multisite Study

This study was designed to increase our understanding about characteristics and the impact of sensory symptoms (SS) and signs of hyperarousal (HA) in individuals with fragile X syndrome (FXS) from childhood through early adulthood and by gender. Data derived from the Fragile X Online Registry With Accessible Research Database (FORWARD), a natural history study of FXS, were analyzed using descriptive statistics and multivariate linear and logistic regression models to examine SS and signs of HA, their impact on behavioral regulation and limitations on the subject/family. The sample (N = 933) consisted of 720 males and 213 females. More males were affected with SS (87% vs. 68%) and signs of HA (92% vs. 79%). Subjects who were endorsed as having a strong sensory response had more comorbidities, including behavioral problems. The predominant SS was difficulty with eye gaze that increased with age in both genders. As individuals age, there was less use of non-medication therapies, such as occupational therapy (OT)/physical therapy (PT), but there was more use of psychopharmacological medications and investigational drugs for behaviors. Multiple regression models suggested that endorsing SS and signs of HA was associated with statistically significantly increased ABC-C-I subscale scores and limited participation in everyday activities. This study improves our understanding of SS and signs of HA as well as their impact in FXS. It supports the need for more research regarding these clinical symptoms, especially to understand how they contribute to well-known behavioral concerns.

Teaching Graduate Students to Translate Nonbehavioral Treatments Into Behavioral Principles

Behavior analytic translations of nonbehavioral treatments were recommended by Brodhead in Behavior Analysis in Practice, 8(1), 70-78 (2015) as part of a decision-making framework for practitioners working on interprofessional treatment teams. Professionals from different disciplines often have overlapping scopes of practice and competence, yet each recommends interventions according to their discipline-specific worldview and training. Nonbehavioral treatment recommendations may be especially challenging for behavior analytic practitioners who are committed to the science of human behavior and who are also ethically obligated to work cooperatively and in the best interest of the client. Learning to translate nonbehavioral treatments into behavior analytic principles and procedures may function as a valuable means of improving professional judgment, thereby promoting evidence-based practice and effective collaboration. Behavioral translations may expose procedures that are, in fact, conceptually systematic, creating more opportunities for behavior analysts to partner in interprofessional care. Using a behavioral skills training package, graduate students of applied behavior analysis were taught to translate nonbehavioral treatments into behavior analytic principles and procedures. All students produced more comprehensive translations following training.

Practical Aspects of ASD Management-What Pediatricians Should Know

The increasing prevalence of autism spectrum disorder (ASD) warrants higher levels of clinical attention to optimally manage children with ASD. There is mounting evidence that early intervention programs can help improve developmental functioning, maladaptive behaviors, and core ASD symptoms. The most thoroughly investigated and evidence-based therapies have been developmental, behavioral, and educational interventions mediated by either professionals or parents. Other commonly available interventions include speech and language therapy, occupational therapy, and social skills training. Pharmacological interventions, where needed, are used as an adjunct to treat severe problem behaviors and manage medical and psychiatric comorbidities. Complementary or alternative medicine (CAM) approaches have not proven to be of any benefit, and some of them may be harmful to the child. As the child's first point of contact, the pediatrician is well-positioned to effectively guide the families to therapies that are evidence-based and safe and also collaborate with various specialists to provide seamless, coordinated care for these children so as to improve their developmental outcomes and social functioning.

Sensory Over-responsivity: A Feature of Childhood Psychiatric Illness Associated With Altered Functional Connectivity of Sensory Networks

BACKGROUND

Sensory over-responsivity (SOR) is recognized as a common feature of autism spectrum disorder. However, SOR is also common among typically developing children, in whom it is associated with elevated levels of psychiatric symptoms. The clinical significance and neurocognitive bases of SOR in these children remain poorly understood and actively debated.

METHODS

This study used linear mixed-effects models to identify psychiatric symptoms and network-level functional connectivity (FC) differences associated with parent-reported SOR in the Adolescent Brain Cognitive Development (ABCD) Study, a large community sample (9 to 12 years of age) (N = 11,210).

RESULTS

Children with SOR constituted 18% of the overall sample but comprised more than half of the children with internalizing or externalizing scores in the clinical range. Controlling for autistic traits, both mild and severe SOR were associated with greater concurrent symptoms of depression, anxiety, obsessive-compulsive disorder, and attention-deficit/hyperactivity disorder. Controlling for psychiatric symptoms and autistic traits, SOR predicted increased anxiety, attention-deficit/hyperactivity disorder, and prodromal psychosis symptoms 1 year later and was associated with FC differences in brain networks supporting sensory and salience processing in datasets collected 2 years apart. Differences included reduced FC within and between sensorimotor networks, enhanced sensorimotor-salience FC, and altered FC between sensory networks and bilateral hippocampi.

CONCLUSIONS

SOR is a common, clinically relevant feature of childhood psychiatric illness that provides unique predictive information about risk. It is associated with differences in brain networks that subserve tactile processing, implicating a neural basis for sensory differences in affected children.

Combined sensory integration therapy plus neurodevelopmental therapy (NT) versus NT alone for motor and attention in children with Down syndrome: a randomized controlled trial

In this study, we aimed to analyze the incremental effects of sensory integration therapy (SIT) plus neurodevelopmental therapy (NT) versus NT alone on the attention and motor skills in children with Down syndrome (DS). We randomly assigned into experimental (i.e. SIT + NT; n = 21) and control (i.e. NT alone; n = 21) groups. While NT was applied to both groups for six weeks, SIT was applied simultaneously to the experimental group for six weeks. Participants' motor functions (Bruininks-Oseretsky Test of Motor Proficiency-Short form (BOT-2 SF)) and attention skills (Stroop TBAG (Turkish Scientific and Technological Research Association) Form) were evaluated before and after treatment (6 weeks later). Stroop TBAG and BOT-2 SF scores of the groups were similar at the baseline (p > 0.05). Significant improvement from baseline was observed in both BOT-2 SF, and Stroop TBAG results in both groups (p < 0.05). In addition, the improvement in both BOT-2 SF and Stroop TBAG results was found to be greater in the experimental group compared to the control group (p < 0.01). There were clear advantages to adding SIT to NT alone when seeking to improve motor and attention skills in children with DS.

Asperger Syndrome (AS): A Review Article

A variant of autism spectrum disorder (ASD) known as Asperger syndrome (AS) is characterized by severe issues with interpersonal, verbal, and nonverbal communication as well as restricted and repetitive patterns of behavior and activities. Although there is no known cause for ASD, various genetic as well as non-genetic risk factors that may act either alone or in combination to induce ASD have been identified. The occurrence of ASD has been increasing worldwide. Co-occurring neuropsychological diseases are frequently present as well. The premise for diagnosis is the observation of abnormal conduct, with diagnostic criteria emphasizing limitations in social interaction and communication as well as constrained, repetitive behavioral patterns, activities, or hobbies. The degree of the illness and the presence of intellectual impairment have a significant impact on the prognosis. Like autism, Asperger's can neither be prevented nor treated. There is no specific medical therapy that can effectively cure all of the symptoms of autism. However, medications may be used as adjuvant therapy for maladaptive behaviors and co-occurring mental problems. The treatment aims to reduce core impairments, increase functional ability, and reduce harmful behaviors that could limit functional skills. It is crucial to provide proper care, establish supportive networks for individuals who are affected and their families, and use effective therapies to enhance functioning and results.

Sensory processing difficulties in psychiatric disorders: A meta-analysis

In clinical practice, many individuals with psychiatric disorders report difficulties in sensory processing, including increased awareness or sensitivity to external stimuli. In this meta-analysis, we examined the sensory processing patterns of adolescent and adult individuals with a broad spectrum of different psychiatric conditions. A systematic search in various databases resulted in the inclusion of 33 studies (N=2008), all using the Adolescent/Adult Sensory Profile (AASP). By comparing diagnostic subgroups to the corresponding reference group of the AASP, we detected a general pattern of sensory processing, indicating elevated levels of low registration, sensory sensitivity and sensory avoiding and lowered sensory seeking behavior in patients with different types of psychiatric disorders. The majority of effect sizes were large to very large. In conclusion, sensory processing difficulties can be considered as a non-specific transdiagnostic phenotype associated with a broad spectrum of psychiatric conditions. Further research into the relevance and role of sensory processing difficulties in psychiatric disorders may improve long-term prognosis and treatment.

Autistic-like Behaviors Associated with a Novel Non-Canonical Splice-Site DDX3X Variant: A Case Report of a Rare Clinical Syndrome

Background. Heterozygous pathogenic variants in the DDX3X gene account for 1−3% of females with intellectual and developmental disabilities (IDD). The clinical presentation is variable, including a wide range of neurological and behavioral deficits and structural defects of the brain. Approximately 52% of affected females remain nonverbal after five years of age. Case presentation: We report a 7 year old nonverbal female with a likely novel de novo pathogenic heterozygous variant in the DDX3X gene affecting the non-canonical splice-site in the intron 1 (NM_001356:c.45+12G>A). The patient presents with features typical for the DDX3X phenotype, such as: movement disorders, behavioral problems, a diagnosis of autism spectrum disorder (ASD), and some other features uncommon for DDX3X such as: muscle hypertonia and spinal asymmetry evaluated through the scoliometer. Conclusions. Due to its rare occurrence, the clinical picture of DDX3X syndrome is yet to be fully determined. So far, behavioral disorders, including those from ASD, and neurological abnormalities seem to be the dominant features of this disorder.

Cognitive, Behavioral, and Sensory Profile of Pallister–Killian Syndrome: A Prospective Study of 22 Individuals

Background: Developmental delay and intellectual disability are two pivotal elements of the phenotype of Pallister–Killian Syndrome (PKS). Our study aims to define the cognitive, adaptive, behavioral, and sensory profile of these patients and to evaluate possible correlations between the different aspects investigated and with the main clinical and demographic variables. Methods: Individuals of any age with genetically confirmed PKS were recruited. Those ≤ 42 months were administered the Bayley Scales of Infant and Toddler Development Third Edition (Bayley-III), and those > 42 months the Vineland Adaptive Behavior Scales—Second Edition (Vineland-II). Stereotyped behaviors (Stereotypy Severity Scale, SSS) and aggressive behaviors (Behavior Problems Inventory—Short Version, BPIs) were assessed in all subjects > 1 year; sensory profile (Child Sensory Profile 2, C-SP2) in all aged 2–18 years. Results: Twenty-two subjects were enrolled (11 F/11 M; age 9 months to 28 years). All subjects ≤ 42 months had psychomotor developmental delay. Of the subjects > 42 months, 15 had low IQ deviation, and 1 in the normal range. Stereotypies were frequent (median SSS-total score 25/68). Lower Vineland-II values corresponded to greater intensity and frequency of stereotypies (p = 0.004 and p = 0.003), and self-injurious behaviors (p = 0.002 and p = 0.002). Patients with severe low vision had greater interference of stereotypies (p = 0.027), and frequency and severity of aggressive behaviors (p = 0.026; p = 0.032). The C-SP2, while not homogeneous across subjects, showed prevalence of low registration and sensory seeking profiles and hypersensitivity to tactile and auditory stimuli. Lower Vineland-II scores correlated with higher Registration scores (p = 0.041), while stereotypies were more frequent and severe in case of high auditory sensitivity (p = 0.019; p = 0.007). Finally, greater sleep impairment correlated with stereotypies and self-injurious behaviors, and lower Vineland-II scores. Conclusions: The present study provides a further step in the investigation of the etiopathogenesis of the syndrome. Furthermore, these aspects could guide rehabilitation therapy through the identification of targeted protocols.

Collaboration between Behavior Analysts and Occupational Therapists in Autism Service Provision: Bridging the Gap

Interdisciplinary collaboration is challenging, but necessary, to meet the needs of individuals with autism spectrum disorder. Among the dyadic interactions in interdisciplinary teams, the relationships between occupational therapy practitioners and board certified behavior analysts are uniquely challenging. The disciplines define evidence-based practice differently and approach intervention from different angles. Furthermore, there are fundamental differences in worldview between the disciplines. Both disciplines offer necessary treatment, and successful collaboration between these disciplines is essential for maximizing outcomes. Hence, finding ways to help bridge the gap between these professions, in particular, is essential. Common barriers to developing collaborative alliances include misperceptions of the other discipline, differences in terminology, and unprofessional behavior. This article reviews the history and foundational concepts of both disciplines, and the common approaches associated with each. In addition, models of collaboration are discussed, with suggestions for enhancing interdisciplinary communication and treatment. Successful collaborative treatment is predicated on an understanding of the value and expertise offered by different disciplines, and requires mutual respect and professional dialogue.

Practitioner's review: medication for children and adolescents with autism spectrum disorder (ASD) and comorbid conditions

Alleviating the multiple problems of children with autism spectrum disorder (ASD) and its comorbid conditions presents major challenges for the affected children, parents, and therapists. Because of a complex psychopathology, structured therapy and parent training are not always sufficient, especially for those patients with intellectual disability (ID) and multiple comorbidities. Moreover, structured therapy is not available for a large number of patients, and pharmacological support is often needed, especially in those children with additional attention deficit/hyperactivity and oppositional defiant, conduct, and sleep disorders.

Characteristics of Idiopathic Sensory Processing Disorder in Young Children

This study described the developmental and behavioral characteristics of children identified with idiopathic sensory processing disorder (SPD) as well as the relations among specific types of SPD as proposed by the nosology presented by Miller et al. (2007), adaptive behavior profiles, and behaviors associated with mental functioning. A retrospective, non-experimental design applying descriptive and correlational analyses was used. Data were obtained from clinic medical records of 78 children ages 2 to 7 years who were identified with sensory processing problems affecting daily life, but who did not meet criteria for any other neurodevelopmental or mental disorders following a comprehensive diagnostic evaluation. Results revealed that all SPD types as described by current typologies were well represented with the most common being the over-responsivity sensory modulation subtype. Within the sample, 53% of the children displayed more than one SPD type. Atypical externalizing and internalizing behavior scores associated with various mental disorders as measured by the child behavior checklist (CBCL) fell in the borderline dysfunctional range. Adaptive behavior for all developmental domains was below average, and the severity of SPD symptoms moderately and positively correlated with behaviors associated with mental disorders, and with lower adaptive behavior performance. It was concluded that symptoms characteristic of the various types of idiopathic SPD overlap substantially suggesting that current typologies may include more types/subtypes than are necessary or clinically useful. Children with SPD share similar, but often less severe pathological behaviors associated with other mental or related neurodevelopmental disorders. Psychometrically sound measures of SPD are needed, and further study of the neural mechanisms involved in sensory processing deficits is vital for validating idiopathic SPD as its own diagnostic entity.

Foot and ankle somatosensory deficits in children with cerebral palsy: A pilot study

PURPOSE

To investigate foot and ankle somatosensory function in children with cerebral palsy (CP).

METHODS

Ten children with spastic diplegia (age 15 ± 5 y; GMFCS I-III) and 11 typically developing (TD) peers (age 15 ± 10 y) participated in the study. Light touch pressure and two-point discrimination were assessed on the plantar side of the foot by using a monofilament kit and an aesthesiometer, respectively. The duration of vibration sensation at the first metatarsal head and medial malleolus was tested by a 128 Hz tuning fork. Joint position sense and kinesthesia in the ankle joint were also assessed.

RESULTS

Children with CP demonstrated significantly higher light touch pressure and two-point discrimination thresholds compared to their TD peers. Individuals with CP perceived the vibration stimulus for a longer period compared to the TD participants. Finally, the CP group demonstrated significant impairments in joint position sense but not in kinesthesia of the ankle joints.

CONCLUSIONS

These findings suggest that children with CP have foot and ankle tactile and proprioceptive deficits. Assessment of lower extremity somatosensory function should be included in clinical practice as it can guide clinicians in designing more effective treatment protocols to improve functional performance in CP.

Neurobiology of sensory processing in autism spectrum disorder

Altered sensory processing and perception has been one of the characteristics of autism spectrum disorder (ASD). In this chapter, we review the neural underpinnings of sensory abnormalities of ASD by examining the literature on clinical, behavioral and neurobiological evidence that underlies the main patterns of sensory integration function and dysfunction. Furthermore, neural differences in anatomy, function and connectivity of different regions underlying sensory processing are also discussed. We conclude that sensory integration intervention is built on the premise of neuroplasticity to improve function and behavior for individuals with ASD.

Application and Perceived Effectiveness of Complementary and Alternative Intervention Strategies for Attention-Deficit/Hyperactivity Disorder: Relationships with Affiliate Stigma

This cross-sectional questionnaire survey study was designed to examine the complementary and alternative intervention strategies (CAIS) employed by caregivers for their children’s attention-deficit/hyperactivity disorder (ADHD) and the associations of affiliate stigma with the employment and rated effectiveness of these strategies in Taiwan. A total of 400 caregivers of children with ADHD participated. CAIS that the caregivers employed and their effectiveness rated by the caregivers were surveyed. Associations of affiliate stigma with the application and rated effectiveness of the strategies were determined using logistic regression analysis. The results indicated that sensory integration (30.3%), exercise training (29.3%), sugar restriction (20.5%), and omega fatty acid supplementation (11.3%) were the most common CAIS that the caregivers employed. Caregivers with stronger affiliate stigma were more likely to employ sensory integration, exercise training, and omega fatty acid supplementation but also rated them as ineffective in treating their children’s ADHD. Various CAIS were employed by the caregivers to manage their children’s ADHD. Affiliate stigma was significantly associated with the application and rated ineffectiveness of several CAIS.

Cerebral palsy in children: a clinical overview

Cerebral palsy (CP) is a disorder characterized by abnormal tone, posture and movement and clinically classified based on the predominant motor syndrome-spastic hemiplegia, spastic diplegia, spastic quadriplegia, and extrapyramidal or dyskinetic. The incidence of CP is 2-3 per 1,000 live births. Prematurity and low birthweight are important risk factors for CP; however, multiple other factors have been associated with an increased risk for CP, including maternal infections, and multiple gestation. In most cases of CP the initial injury to the brain occurs during early fetal brain development; intracerebral hemorrhage and periventricular leukomalacia are the main pathologic findings found in preterm infants who develop CP. The diagnosis of CP is primarily based on clinical findings. Early diagnosis is possible based on a combination of clinical history, use of standardized neuromotor assessment and findings on magnetic resonance imaging (MRI); however, in most clinical settings CP is more reliably recognized by 2 years of age. MRI scan is indicated to delineate the extent of brain lesions and to identify congenital brain malformations. Genetic tests and tests for inborn errors of metabolism are indicated based on clinical findings to identify specific disorders. Because CP is associated with multiple associated and secondary medical conditions, its management requires a multidisciplinary team approach. Most children with CP grow up to be productive adults.

Identification, Evaluation, and Management of Children With Autism Spectrum Disorder

Autism spectrum disorder (ASD) is a common neurodevelopmental disorder with reported prevalence in the United States of 1 in 59 children (approximately 1.7%). Core deficits are identified in 2 domains: social communication/interaction and restrictive, repetitive patterns of behavior. Children and youth with ASD have service needs in behavioral, educational, health, leisure, family support, and other areas. Standardized screening for ASD at 18 and 24 months of age with ongoing developmental surveillance continues to be recommended in primary care (although it may be performed in other settings), because ASD is common, can be diagnosed as young as 18 months of age, and has evidenced-based interventions that may improve function. More accurate and culturally sensitive screening approaches are needed. Primary care providers should be familiar with the diagnostic criteria for ASD, appropriate etiologic evaluation, and co-occurring medical and behavioral conditions (such as disorders of sleep and feeding, gastrointestinal tract symptoms, obesity, seizures, attention-deficit/hyperactivity disorder, anxiety, and wandering) that affect the child's function and quality of life. There is an increasing evidence base to support behavioral and other interventions to address specific skills and symptoms. Shared decision making calls for collaboration with families in evaluation and choice of interventions.  This single clinical report updates the 2007 American Academy of Pediatrics clinical reports on the evaluation and treatment of ASD in one publication with an online table of contents and section view available through the American Academy of Pediatrics Gateway to help the reader identify topic areas within the report.

Review: Exteroceptive Sensory Abnormalities in Childhood and Adolescent Anxiety and Obsessive-Compulsive Disorder: A Critical Review

OBJECTIVE

Childhood anxiety and obsessive-compulsive disorder (OCD) are defined by fear, worry, and uncertainty, but there is also evidence that affected children possess exteroceptive sensory abnormalities. These sensory features may often instigate symptoms and cause significant distress and functional impairment. In addition, a purported class of conditions known as "sensory processing disorders" may significantly overlap with childhood anxiety and OCD, which provides further support for a connection between abnormal sensation and fear-based psychopathology.

METHOD

The current review was conducted to synthesize and to critically evaluate the existing research on exteroceptive sensory abnormalities in childhood anxiety and OCD. Because of the paucity of research in this area, studies with adult populations were also briefly reviewed.

RESULTS

The review found significant support for the notion that sensory abnormalities are common in children with anxiety disorders and OCD, but there are significant limitations to research in this area that prevent firm conclusions.

CONCLUSION

Potential avenues for future research on sensory features of pediatric anxiety and OCD are discussed.

Simultaneous use of sensory stimulation and motor exercise improves the manual skills of educable children with mental retardation at preprimary and primary school levels

Background: Children with mental retardation have various clinical problems. They mostly have motor delay and sensory deficit. Neurorehabilitation focuses on restoring remaining abilities. Thus, the present study was designed to study the effects of simultaneous use of sensory-motor therapy on manual skills of children with mental retardation. Methods: In this study, 120 educable boys and girls with mental retardation (9-12 years) were selected from 2 preprimary and primary exceptional centers in Tehran using stratified sampling method considering the geographical dispersion. The participants were divided into 2 equal trial and control groups using simple random sampling. Lincoln-Oseretsky Motor Development Scale, Purdue Pegboard test, and Handwriting Legibility Checklist of Persian Language were used. Simultaneous sensory stimulations and motor exercises were used for 3 one-hour weekly sessions for 12 consecutive weeks. Pre and posttests were done for evaluation. Using parametric paired and independent samples t tests, the findings were analyzed in SPSS 23. Results: The manual skills significantly improved following therapeutic use of simultaneous sensory stimulation and motor exercise (p=0.001). In the control group, the pre and post evaluation difference was not significant (p=0.813) Conclusion: Based on the findings of this study, simultaneous use of sensory-motor techniques can have better clinical results in the trial group compared to the control group. Thus, these types of techniques should be used more in clinics. However, further studies are needed for more comparison between separate applications of these techniques.

Adaptation and psychometric properties of the Polish version of the Short Sensory Profile 2

The article presents findings from the validation of the Polish version of the Short Sensory Profile, 2nd edition (SSP-2-PL).A total of 1230 participants were recruited: 310 diagnosed with autism spectrum disorder (ASD), 264 with nonspectrum neurodevelopmental disorders, and 656 typically developing (TD). The reliability and validity of the questionnaire were estimated using several methods, including internal consistency, test-retest, and factor analysis.Exploratory factor analysis identified a unidimensional solution in both the TD and ASD groups. The structure of SSP-2 seems to be homogeneous; therefore, the findings support the validity of calculating the SSP-2 overall score. Cronbach alphas and intraclass correlation coefficients exceeded 0.90 for overall total in all study groups. The Social Communication Questionnaire total score correlated moderately with SSP-2 scores. A 1-way analysis of variance yielded statistically significant differences at P < .001 between groups on all scales/quadrants and the overall score. Our results indicate greater severity of sensory processing problems among children with ASD and non-ASD disorders than among TD peers. Among children with ASD, 85% experienced problems with sensory processing. Scores in SSP-2-PL were not affected by the children's age, gender, informant, and informant's level of education.To the best of our knowledge, this is the 1st study on non-English participants using a revised version of the SSP-2. The results confirm the prevalence of sensory processing problems among children with neurodevelopmental disorders, especially with ASD. SSP-2-PL has high reliability in terms of both internal consistency and stability of scores. The results suggest that SSP-2 overall score could be used for screening purposes, namely to identify sensory processing and behavioral problems combined into one factor. Further analyzes of the SSP-2 factor structure are needed to confirm the findings of the present study.

Preterm Perinatal Hypoxia-Ischemia Does not Affect Somatosensory Evoked Potentials in Adult Rats

Somatosensory evoked potentials (SSEPs) are a valuable tool to assess functional integrity of the somatosensory pathways and for the prediction of sensorimotor outcome in perinatal injuries, such as perinatal hypoxia-ischemia (HI). In the present research, we studied the translational potential of SSEPs together with sensory function in the male adult rat with perinatal HI compared to the male healthy adult rat. Both somatosensory response and evoked potential were measured at 10-11 months after global perinatal HI. Clear evoked potentials were obtained, but there were no group differences in the amplitude or latency of the evoked potentials of the preceding sensory response. The bilateral tactile stimulation test was also normal in both groups. This lack of effect may be ascribed to the late age-of-testing and functional recovery of the rats.

Prescribing Physical, Occupational, and Speech Therapy Services for Children With Disabilities

Pediatric health care providers are frequently responsible for prescribing physical, occupational, and speech therapies and monitoring therapeutic progress for children with temporary or permanent disabilities in their practices. This clinical report will provide pediatricians and other pediatric health care providers with information about how best to manage the therapeutic needs of their patients in the medical home by reviewing the International Classification of Functioning, Disability and Health; describing the general goals of habilitative and rehabilitative therapies; delineating the types, locations, and benefits of therapy services; and detailing how to write a therapy prescription and include therapists in the medical home neighborhood.

The Importance of Sensory Processing in Mental Health: A Proposed Addition to the Research Domain Criteria (RDoC) and Suggestions for RDoC 2.0

The time is ripe to integrate burgeoning evidence of the important role of sensory and motor functioning in mental health within the National Institute of Mental Health's [NIMH] Research Domain Criteria [RDoC] framework (National Institute of Mental Health, n.d.a), a multi-dimensional method of characterizing mental functioning in health and disease across all neurobiological levels of analysis ranging from genetic to behavioral. As the importance of motor processing in psychopathology has been recognized (Bernard and Mittal, 2015; Garvey and Cuthbert, 2017; National Institute of Mental Health, 2019), here we focus on sensory processing. First, we review the current design of the RDoC matrix, noting sensory features missing despite their prevalence in multiple mental illnesses. We identify two missing classes of sensory symptoms that we widely define as (1) sensory processing, including sensory sensitivity and active sensing, and (2) domains of perceptual signaling, including interoception and proprioception, which are currently absent or underdeveloped in the perception construct of the cognitive systems domain. Then, we describe the neurobiological basis of these psychological constructs and examine why these sensory features are important for understanding psychopathology. Where appropriate, we examine links between sensory processing and the domains currently included in the RDoC matrix. Throughout, we emphasize how the addition of these sensory features to the RDoC matrix is important for understanding a range of mental health disorders. We conclude with the suggestion that a separate sensation and perception domain can enhance the current RDoC framework, while discussing what we see as important principles and promising directions for the future development and use of the RDoC.

Increased risk of developing psychiatric disorders in children with attention deficit and hyperactivity disorder (ADHD) receiving sensory integration therapy: a population-based cohort study

Parents of children with attention deficit hyperactivity disorder (ADHD) have been found to prefer sensory integration (SI) training rather than guideline-recommended ADHD treatment. This study investigated whether SI intervention for children with ADHD was associated with a reduced risk of subsequent mental disorders. From children < 8-years-old newly diagnosed with ADHD in a nationwide population-based dataset, we established a SI cohort and a non-SI cohort (N =  1945) matched by propensity score. Incidence and hazard ratios of subsequent psychiatric disorders were compared after a maximum follow-up of 9 years. The incidence of psychiatric disorders was 1.4-fold greater in the SI cohort, with an adjusted hazard ratio of 1.41 (95% confidence interval 1.20-1.67), comparing to the non-SI cohort. Risks were elevated for emotional disturbances, conduct disorders, and adjustment disorders independent of age, gender, or comorbidity. Among children with only psychosocial intervention, the incidence of psychiatric disorders was 3.5-fold greater in the SI cohort than in the non-SI cohort. To our knowledge, this is the first study to report an increased risk of developing psychiatric disorders for children with ADHD who received SI compared to those who did not. Potential adverse effects of SI for ADHD children should be carefully examined and discussed before practice.

Creating a Sensory-Friendly Pediatric Emergency Department

INTRODUCTION

For children with autism spectrum disorder (ASD) and sensory-processing disorder (SPD), an unexpected visit to the emergency department can be an overwhelming experience that creates intensifying behaviors and an unsafe clinical interaction for the child, nurses, and providers. Although resources exist to help nurses work with this specialized group, there are limited examples of the challenges and opportunities of modifying an emergency department to be a place where nurses can provide sensory-informed care.

METHODS

Guided by Watson's Theory of Caring, nurses and child life specialists in our pediatric emergency department initiated a practice improvement (PI) project to create a sensory-friendly emergency department. The nurses (1) engaged with community members and families, (2) examined current practices, (3) modified the patient care environment, (4) collaborated in an interprofessional educational session, and (5) created a shared vision for the modified patient-care environment.

RESULTS

This article describes the nurse-initiated PI process and the journey to create an evidence-based sensory-friendly pediatric emergency department. A model is presented so that other facilities can embark on their own initiative, and case studies are used to evaluate project outcomes.

DISCUSSION

Integrating current evidence, staff suggestions, community input, and expert advice allowed us to find creative solutions to the unique sensory needs of children who visit our emergency department. Modifying both the patient-care environment and the patient-flow process to accommodate for the needs of children with ASD/SPD created a more peaceful and healing environment for children and their families and gave nurses the support they needed to provide sensory-informed care.

Public Perception of Autism Treatments: The Role of Credibility and Evidence

We explored the influence of credibility and evidence on public perceptions of ASD treatments using survey methodology. Participants (N = 379) read texts about different ASD treatments. The text presentation was based on a 2 × 2 within-subjects factorial design with treatment status [evidence based practices (EBP) vs. non-EBP] and source credibility in the text (credible vs. non-credible) as the independent variables. An instructional manipulation condition served as a between subjects factor. Respondents were more familiar with non-EBPs than EBPs, but viewed EBPs as being more credible and were more likely to endorse them compared to pseudoscientific practices. Interactions between source credibility and instructional manipulation were found on ratings of credibility and recommendation of both EBP and non-EBP texts. Implications of these findings are discussed.

High-risk follow-up: Early intervention and rehabilitation

Early detection of childhood disability is possible using clinically available tools and procedures. Early detection of disability enables early intervention that maximizes the child's outcome, prevents the onset of complications, and supports parents. In this chapter, first we summarize the best-available tools for accurately predicting major childhood disabilities early, including autism spectrum disorder, cerebral palsy, developmental coordination disorder, fetal alcohol spectrum disorder, intellectual disability, hearing impairment, and visual impairment. Second, we provide an overview of the preclinical and clinical evidence for inducing neuroplasticity following brain injury. Third, we describe and appraise the evidence base for: (a) training-based interventions that induce neuroplasticity, (b) rehabilitation interventions not focused on inducing neuroplasticity, (c) complementary and alternative interventions, (d) environmental enrichment interventions in the neonatal intensive care and community settings, and (e) parent-child interaction interventions in the neonatal intensive care and community settings. Fourth, we explore emergent treatment options at clinical trial, designed to induce brain repair following injury. In conclusion, early diagnosis enables early intervention, which improves child and parent outcomes. We now know which interventions provide the biggest gains and the information can be used to help inform parental decision making when designing treatment plans for their children.

Stochastic resonance stimulation improves balance in children with cerebral palsy: a case control study

Background

Stochastic Resonance (SR) Stimulation has been used to enhance balance in populations with sensory deficits by improving the detection and transmission of afferent information. Despite the potential promise of SR in improving postural control, its use in individuals with cerebral palsy (CP) is novel. The objective of this study was to investigate the immediate effects of electrical SR stimulation when applied in the ankle muscles and ligaments on postural stability in children with CP and their typically developing (TD) peers.

Methods

Ten children with spastic diplegia (GMFCS level I- III) and ten age-matched TD children participated in this study. For each participant the SR sensory threshold was determined. Then, five different SR intensity levels (no stimulation, 25, 50, 75, and 90% of sensory threshold) were used to identify the optimal SR intensity for each subject. The optimal SR and no stimulation condition were tested while children stood on top of 2 force plates with their eyes open and closed. To assess balance, the center of pressure velocity (COPV) in anteroposterior (A/P) and medial-lateral (M/L) direction, 95% COP confidence ellipse area (COPA), and A/P and M/L root mean square (RMS) measures were computed and compared.

Results

For the CP group, SR significantly decreased COPV in A/P direction, and COPA measures compared to the no stimulation condition for the eyes open condition. In the eyes closed condition, SR significantly decreased COPV only in M/L direction. Children with CP demonstrated greater reduction in all the COP measures but the RMS in M/L direction during the eyes open condition compared to their TD peers. The only significant difference between groups in the eyes closed condition was in the COPV in M/L direction.

Conclusions

SR electrical stimulation may be an effective stimulation approach for decreasing postural sway and has the potential to be used as a therapeutic tool to improve balance. Applying subject-specific SR stimulation intensities is recommended to maximize balance improvements. Overall, balance rehabilitation interventions in CP might be more effective if sensory facilitation methods, like SR, are utilized by the clinicians.

Association between sensory modulation and daily activity function of children with attention deficit/hyperactivity disorder and children with typical development

BACKGROUND

The severity of the functional difficulties of children with attention-deficit/hyperactivity disorder (ADHD) is heterogeneous and may be affected by measurable factors.

AIMS

To characterize subgroups of children with ADHD with or without sensory modulation difficulties (SMD) and the association between sensory modulation and daily activity function in children with ADHD and children with typical development.

METHODS

38 children with ADHD and 39 controls (ages 8-11) were recruited and assessed, using the Conner's Parent Rating Scale-Revised: Short Form, the Short Sensory Profile (SSP) and the Children Activity Scale for Parents (ChAS-P).

RESULTS

The total SSP score of the ADHD group was lower (142.13 vs. 180.08; t=-8.23, p < 0.001) with a higher proportion of SMD (65.8% vs. 2.6%, χ² = 34.46, p < 0.001). The daily function of children with ADHD was lower than controls (mean ChAS-P: 3.95 vs. 4.78, p < 0.001). The difference was significant for children with ADHD and SMD (3.70 versus 4.81, p < 0.001), but not significant for children with ADHD and typical SSP (4.42 versus 4.81, p=0.35).

CONCLUSION

In this pilot study, we found that SMD, in children with ADHD is correlated with daily activity consequences. Hence, it should be evaluated in children with ADHD and addressed in their treatment plan.

Longitudinal assessment of stability of sensory features in children with autism spectrum disorder or other developmental disabilities

Prior research on the stability of sensory processing problems in children with autism spectrum disorder (ASD) or other developmental disabilities (DD) has produced inconsistent results. We employed a longitudinal study design to assess the stability of three clinical sensory response patterns: hyporesponsiveness; hyperresponsiveness; and sensory interests, repetitions, and seeking behaviors (SIRS). Parents of children with ASD (n = 55) or DD (n = 35) responded to sensory questionnaires at two time points (T1 and T2) separated by 3.3 years on average, with the children aged 2-12 years (M = 5.69 ± 2.46) at the first assessment. For each sensory response pattern, regression analysis revealed that, for both ASD and DD groups, scores at T1 were strong predictors of scores at T2. Over the longitudinal assessment interval, there was a significant mean decline in severity for SIRS in both groups and for hyporesponsiveness in the ASD group. Parental estimates of the amount of therapy services received were positively associated with the severity of sensory features at T2, an outcome that may result from increased intervention dosages being administered to children who fail to improve over time. The results are discussed in terms of person-centered and environmental considerations, which, in combination, have the capacity to affect stability outcomes for sensory features. Autism Research 2019, 12: 100-111. © 2018 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: Children with autism spectrum disorder (ASD) and other developmental disabilities (DD) may process sensory information differently from those who do not have ASD. For example, some children may be over-responsive or under-responsive to sound or touch. In this study, we showed that sensory features in preschool/school-aged children with ASD and DD tend to decrease on average over a several year period. However, individual children tend to retain their ranking (low or high in sensory features) in comparison to other children over time.

Single-case synthesis tools I: Comparing tools to evaluate SCD quality and rigor

Tools for evaluating the quality and rigor of single case research designs (SCD) are often used when conducting SCD syntheses. Preferred components include evaluations of design features related to the internal validity of SCD to obtain quality and/or rigor ratings. Three tools for evaluating the quality and rigor of SCD (Council for Exceptional Children, What Works Clearinghouse, and Single-Case Analysis and Design Framework) were compared to determine if conclusions regarding the effectiveness of antecedent sensory-based interventions for young children changed based on choice of quality evaluation tool. Evaluation of SCD quality differed across tools, suggesting selection of quality evaluation tools impacts evaluation findings. Suggestions for selecting an appropriate quality and rigor assessment tool are provided and across-tool conclusions are drawn regarding the quality and rigor of studies. Finally, authors provide guidance for using quality evaluations in conjunction with outcome analyses when conducting syntheses of interventions evaluated in the context of SCD.

The neurological toxicity of heavy metals: A fish perspective

The causes of neurodegenerative diseases are complex with likely contributions from genetic susceptibility and environmental exposures over an organism's lifetime. In this review, we examine the role that aquatic models, especially zebrafish, have played in the elucidation of mechanisms of heavy metal toxicity and nervous system function over the last decade. Focus is applied to cadmium, lead, and mercury as significant contributors to central nervous system morbidity, and the application of numerous transgenic zebrafish expressing fluorescent reporters in specific neuronal populations or brain regions enabling high-resolution neurodevelopmental and neurotoxicology research.

Sensory-Based Approaches in Intervention for Children With Autism Spectrum Disorder: Influences on Occupational Therapists' Recommendations and Perceived Benefits

OBJECTIVE

We investigated factors that influenced occupational therapists' beliefs about and use of sensory-based approaches for children with autism spectrum disorder (ASD).

METHOD

Occupational therapists working with children with ASD (N = 211 from 16 countries) completed an online survey addressing their work experience, training, use of sensory-based approaches, and beliefs and perceptions about the effects of the approaches. Linear regression was used to determine predictors of use of and beliefs about sensory-based approaches.

RESULTS

Most respondents (98%) used sensory-based approaches for children with ASD and would recommend the approaches for 57% of the children they treated. Having a mentor who promoted sensory-based approaches and practicing outside North America and Australia predicted greater use and perceived effectiveness of these approaches. Less than 5 yr of occupational therapy experience predicted less use of the approaches.

CONCLUSION

Respondents selectively used sensory-based approaches for children with ASD and were influenced by country of residence, clinical experience, and mentorship.

Using Home-Program Adherence App in Pediatric Therapy: Case Study of Sensory Processing Disorder

BACKGROUND

Pediatric therapies adopt a family-centered approach that encourages a caregiver's involvement in therapy. Contextual interventions in the child's natural environment have been effective in generalization of skills and increasing of child participation in daily activities. The use of home programs is common across a variety of conditions, but adherence has been challenging. Apps have been demonstrated to promote medication adherence and physical activity maintenance.

INTRODUCTION

This study suggested and tested a construct for features required for caregivers' behavioral modification during home programs in pediatric therapy.

MATERIALS AND METHODS

SensoryTreat is an adherence promoting app for home-program treatments of children with sensory processing disorders. The app was evaluated by testing availability of desired features, usage frequency, impact on adherence with home programs, and parental sense of competence.

RESULTS

Results suggest a strong significant correlation between SensoryTreat usage frequency and families' adherence with home programs, as well as a strong significant correlation between relevancy and usefulness of SensoryTreat's interventional content, and parental competence and their adherence with home programs.

DISCUSSION

Using SensoryTreat twice or more per week increases parental adherence with home programs. Content plays an important role in promoting adherence and parental sense of competence, yet, as usage frequency grows the interventional content habituates, and other features as goal setting and feedback logs have significant impact on parental competence and adherence with home programs over time.

CONCLUSIONS

These findings indicate that the content and features of SensoryTreat app have the potential to promote adherence of families with pediatric therapy home programs.

El Trastorno de Aprendizaje Procedimental y su intervención psicopedagógica

El TAP es una afectación poco conocida. Ha sido denominado de múltiples formas según los diferentes autores. Se diagnostica con menos frecuencia que otros trastornos del aprendizaje/neurodesarrollo debido a que los síntomas se confunden con frecuencia con los de otras patologías. Se caracteriza especialmente por una perturbación de la coordinación motora, aunque la causa explicativa del mismo reside en la dificultad para el desarrollo de ciertas habilidades perceptivo-motoras y de rutinas cognitivas. Actualmente hay una gran variedad de enfoques de intervención (sobre todo en el ámbito motor), con diverso grado de evidencia científica.  

Task-oriented interventions for children with developmental co-ordination disorder

BACKGROUND

Developmental co-ordination disorder (DCD) is a common childhood disorder, which can persist into adolescence and adulthood. Children with DCD have difficulties in performing the essential motor tasks required for self-care, academic, social and recreational activities.

OBJECTIVES

To assess the effectiveness of task-oriented interventions on movement performance, psychosocial functions, activity, and participation for children with DCD and to examine differential intervention effects as a factor of age, sex, severity of DCD, intervention intensity, and type of intervention.

SEARCH METHODS

In March 2017, we searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase, 13 other databases, and five trials registers. We also searched reference lists, and contacted members of the mailing list of the International Conference on DCD to identify additional studies.

SELECTION CRITERIA

We included all randomised controlled trials (RCTs) and quasi-RCTs that compared the task-oriented intervention with either an inactive control intervention or an active control intervention in children and adolescents aged four to 18 years with a diagnosis of DCD.Types of outcome measures included changes in motor function, as assessed by standardised performance outcome tests and questionnaires; adverse events; and measures of participation.

DATA COLLECTION AND ANALYSIS

All review authors participated in study selection, data extraction, and assessments of risk of bias and quality, and two review authors independently performed all tasks. Specifically, two review authors independently screened titles and abstracts to eliminate irrelevant studies, extracted data from the included studies, assessed risk of bias, and rated the quality of the evidence using the GRADE approach. In cases of ambiguity or information missing from the paper, one review author contacted trial authors.

MAIN RESULTS

This review included 15 studies (eight RCTs and seven quasi-RCTs). Study characteristicsThe trials included 649 participants of both sexes, ranging in age from five to 12 years.The participants were from Australia, Canada, China, Sweden, Taiwan, and the UK.Trials were conducted in hospital settings; at a university-based clinic, laboratory, or centre; in community centres; at home or school, or both at home and school.The durations of task-oriented interventions were mostly short term (less than six months), with the total number of sessions ranging from five to 50. The length of each session ranged from 30 to 90 minutes, and the frequencies ranged from once to seven times per week.We judged the risk of bias as moderate to high across the studies. Some elements were impossible to achieve (such as blinding of administering personnel or participants).

KEY RESULTS

primary outcomesA meta-analysis of two RCTs and four quasi-RCTs found in favour of task-oriented interventions for improved motor performance compared to no intervention (mean difference (MD) -3.63, 95% confidence interval (CI) -5.88 to -1.39; P = 0.002; I² = 43%; 6 trials, 169 children; very low-quality evidence).A meta-analysis of two RCTs found no effect of task-oriented interventions for improved motor performance compared to no intervention (MD -2.34, 95% CI -7.50 to 2.83; P = 0.38; I² = 42%; 2 trials, 51 children; low-quality evidence).Two studies reported no adverse effects or events. Through personal correspondence, the authors of nine studies indicated that no injuries had occurred.

KEY RESULTS

secondary outcomesDue to the limited number of studies with complete and consistent data, we were unable to perform any meta-analyses on our secondary measures or any subgroup analysis on age, sex, severity of DCD, and intervention intensity.

AUTHORS' CONCLUSIONS

We have very little confidence in the effect estimate: the true effect is likely to be substantially different from the estimate of effect. The conclusions drawn from previous reviews, which unanimously reported beneficial effects of intervention, are inconsistent with our conclusions. This review highlights the need for carefully designed and executed RCTs to investigate the effect of interventions for children with DCD.
