[PMID: 38811009 DOI: 10.1080/00222895.2024.2361103] [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: 11/22/2023] [Revised: 05/08/2024] [Accepted: 05/23/2024] [Indexed: 05/31/2024]
Abstract
Attention Deficit Hyperactivity Disorder (ADHD) is characterized by inappropriate levels of activity, impulsivity, and inattention. Developmental Coordination Disorder (DCD) is a condition involving challenges in acquiring and executing motor skills. This cross-sectional study aimed to distinguish motor symptoms between ADHD and ADHD/DCD. A total of 283 children from two elementary schools underwent screening, leading to the identification of 27 children with ADHD. The assessment encompassed the Swanson, Nolan, and Pelham-IV Questionnaire (SNAP-IV), the Movement Assessment Battery for Children (MABC-2), and the Motor Development Scale (MDS). The groups consisted of ADHD (14) and ADHD/DCD (13). Statistical analysis revealed significant differences in general motor age means between groups (p = 0.016), indicating inferior performance in the ADHD/DCD group. The coexistence of DCD significantly influenced the motor performance of children with ADHD, particularly in fine motor skills (p = 0.018) and balance (p = 0.033). Both groups exhibited mild to moderate risk of motor development delay. It is suggested that ADHD is associated with motor problems, even when DCD is not co-occurring. Specific domain-based analysis could demonstrate how the co-occurrence with DCD affects the motor performance of children with ADHD, with statistically significant differences observed in fine motor skills and balance.

Abstract
BACKGROUND Attention deficit hyperactivity disorder (ADHD) is a prevalent neurodevelopmental disorder characterized by diverse clinical manifestations including inattention, hyperactivity and impulsivity. OBJECTIVE The present study aims to investigate the effects of neurocognitive training (NT), a personalized and specialized exercise programme on symptoms, attention and dynamic balance in treatment-naïve children diagnosed with ADHD. METHODS Fourteen treatment-naïve children aged 7-12 years diagnosed with ADHD were enrolled in the intervention group. The NT intervention was administered weekly for 10 consecutive weeks, supplemented by a structured home exercise programme for 6 days a week over the same 10-week period. ADHD-related symptoms, attention and dynamic balance were assessed in pre-treatment, post-treatment, 6 months, and 12 months. Fifteen typically developing (TD) children, matched for age, underwent evaluation only once to establish baseline normative values. RESULTS Following the NT (post-treatment), significant improvements were observed in hyperactivity-impulsivity scores, oppositional-defiant behaviours and dynamic balance when compared to the TD children (p < 0.05). In the ADHD group, a significant difference was found in the long term (12-month follow-up) in hyperactivity-impulsivity, oppositional-defiant behaviours and dynamic balance (p < 0.05). CONCLUSION The findings suggest that the NT yields favourable effects on hyperactivity-impulsivity, oppositional defiant behaviours and dynamic balance in children diagnosed with ADHD, with these improvements appearing to be sustained over the long term. CLINICAL TRIAL REGISTRATION NUMBER NCT04707040.

Abstract
AbstractThis study aimed to refine and validate a multidomain developmental survey (MDS) used by the Brain Balance® (BB) program. Data were analyzed on 47,571 participants (68.5% male; 4–18 years) whose parents completed the survey before/after 3 months of in-center BB participation. Exploratory Factor Analysis was applied to a training sample (n = 28,254), reducing the original item pool from 98 to 31 items and suggesting a six-factor solution. The six factors were labeled as negative emotionality, reading/writing difficulties, hyperactive-disruptive, academic disengagement, motor/coordination problems, and social communication problems. Exploratory Structural Equation Modeling was applied to two validation samples (n = 9394 and 9923), and the factor structure demonstrated strong goodness-of-fit. Test–retest reliability coefficients (per Pearson correlations) were high for each of the subscales. Finally, the survey’s factor structure appeared equivalent across four groups stratified by reported gender and adolescent status. Overall, the BB-MDS demonstrated strong measurement properties, including validated factor structure, internal reliability, test–retest reliability, and measurement invariance.

Abstract
Background Previous studies have shown that physical activity interventions positively affect core symptoms and executive functioning in children with attention-deficit/hyperactivity disorder (ADHD). However, comparisons between different physical activity interventions still need to be made. This study is the first to analyze the effects of 10 different types of physical activity on children with ADHD through a network meta-analysis. Methods PubMed, Embase, Web of Science, and Cochrane Library databases were searched for randomized controlled trials on the effects of physical activity interventions on children with ADHD. The search time frame was from database creation to October 2022. Two investigators independently performed literature screening, extraction, and quality assessment. Network meta-analysis was performed with Stata 15.1. Results A total of 31 studies were included, and the results indicated that perceptual-motor training was the most effective in terms of motor ability and working memory (SUCRA = 82.7 and 73.3%, respectively). For attention problems and cognitive flexibility, aquatic exercise was the most effective (SUCRA = 80.9 and 86.6%, respectively). For social problems, horsemanship was the most effective (SUCRA = 79.4%). For inhibition switching, cognitive-motor training was the most effective (SUCRA = 83.5%). Conclusion Our study revealed that aquatic exercise and perceptual-motor training had a superior overall performance. However, the effects of various physical activity interventions on different indicators in children with ADHD can vary depending on the individual and the intervention's validity. To ensure an appropriate physical activity intervention is selected, it is important to assess the severity of symptoms exhibited by children with ADHD beforehand.

Development and Verification of Postural Control Assessment Using Deep-Learning-Based Pose Estimators: Towards Clinical Applications. Occup Ther Int 2022; 2022:6952999. [DOI: 10.1155/2022/6952999] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/07/2022] [Revised: 09/29/2022] [Accepted: 09/30/2022] [Indexed: 12/02/2022] Open
Abstract
Occupational therapists evaluate various aspects of a client’s occupational performance. Among these, postural control is one of the fundamental skills that need assessment. Recently, several methods have been proposed to estimate postural control abilities using deep-learning-based approaches. Such techniques allow for the potential to provide automated, precise, fine-grained quantitative indices simply by evaluating videos of a client engaging in a postural control task. However, the clinical applicability of these assessment tools requires further investigation. In the current study, we compared three deep-learning-based pose estimators to assess their clinical applicability in terms of accuracy of pose estimations and processing speed. In addition, we verified which of the proposed quantitative indices for postural controls best reflected the clinical evaluations of occupational therapists. A framework using deep-learning techniques broadens the possibility of quantifying clients’ postural control in a more fine-grained way compared with conventional coarse indices, which can lead to improved occupational therapy practice.

Effects of equine-assisted activities on attention and quality of life in children with cerebral palsy in a randomized trial: examining the comorbidity with attention-deficit/hyperactivity disorder. BMC Pediatr 2021; 21:135. [PMID: 33740922 PMCID: PMC7976699 DOI: 10.1186/s12887-021-02597-0] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/08/2020] [Accepted: 03/07/2021] [Indexed: 12/02/2022] Open
Abstract
Background Attention problems and decreased quality of life are frequently accompanied in Cerebral Palsy (CP), which can negatively affect rehabilitation of physical disability. However, the majority of affected children remain untreated in the aspects of attention or psychosocial factors. Equine-Assisted Activities and Therapies (EAAT) use horse as a therapeutic modality including grooming as well as mounted riding activities in which patients exercise and experience mounted stimulation. It is known to help improve attention in children with ADHD, so that it can be an exercise therapy that is expected to improvement of attention as well as rehabilitating effects in CP patients. EAA may be a promising strategy to address the unmet need for CP patients. This study aims to investigate the efficacy of EAA for children with CP, those with both CP and ADHD and confirm the comorbidity between CP and ADHD. Methods Forty-six children with cerebral palsy participated in this study. For the exercise group, they participated in a 40-min session twice a week for a 16-week period, while the control group engaged in daily life without any special treatments. Each children individually were assessed on attention and psychological wellbeing at baseline and post-treatment. Comorbidity were identified based on the Diagnostic and Statistical Manual of Mental Disorder 5th edition (DSM-5) and confirmed by Korean Kiddie-Schedule for Affective Disorders and Schizophrenia Present and Lifetime Version (K-SADS-PL). Results Perseveration rated using the Conner’s Performance Test (CPT) showed a significant decrease only in the exercise group (p < .024). However, no significant improvement in children’s quality of life was observed after EAA program compared with control group. Among the total participants, fifteen children (31.91%) were diagnosed with ADHD. When conducting an additional analysis with the subsample of CP patients diagnosed with ADHD, the d’, commission error and perseveration showed a significant decrease only in the exercise group. Children with CP and ADHD reported an improvement in quality of life both in exercise and control group, but only in the exercise group social functioning exhibited a significant difference. Conclusion The positive effects of the EAA on attention and quality of life were confirmed. Children with CP in the exercise group were more capable to sustain their attention longer. Those with CP and ADHD showed an increase in attention and perceived to have better social skills after receiving 16 weeks of EAA compared to those in the control group. Considering high comorbidity of CP and ADHD, it seems that the EAA program could be the better alternative treatment for CP with attentional problem. The results of this study will contribute to growing evidence for the efficacy of EAA in children especially with CP and ADHD. Trial registration This trial was registered on ClinicalTrials.gov (NCT03870893). Registered 26 July 2017.

Abstract
INTRODUCTION One of the psychiatric disorders related to childhood is attention deficit hyperactivity disorder that can negatively affect the family interactions of these children. Parents of these children, especially the mother as the main caregiver, need comprehensive training to make a positive difference in their attitudes and behaviors with these children. The purpose of this study was to investigate the effect of emotion regulation training on family relationships in hyperactive children. METHODS This was a randomized clinical trial study with a control group performed on eighty mothers of hyperactive children who were selected randomly. The intervention group members attended emotion regulation skills training sessions for one session of 90 min each week for 8 weeks. During the training course in the intervention group, the control group did not receive any training. Data collection tools included demographic information questionnaires, Mother-Child Relationship Evaluation, and Rahim Organizational Conflict Inventory-II. Data analysis was performed by descriptive statistics and the analysis of covariance. RESULTS The mean scores of the mother-child relationship in the intervention group showed a significant improvement in the subscales of acceptance, overprotection, facilitation, and rejection (P < 0.0001). The results of this research also showed improvements in all the five communication styles of integrating, avoiding, compromising, obliging (P < 0.0001), and dominating (P < 0.012) between spouses. CONCLUSION It seems that the emotion regulation training approach in mothers with hyperactive children improved both the mother-child relationship and the interactive spousal styles and can be considered by the managers of treatment and rehabilitation field as an adjunctive therapy for the families of these children.

Abstract
This study aimed to leverage computer vision (CV) technology to develop a technique for quantifying postural control. A conventional quantitative index, occupational therapists' qualitative clinical evaluations, and CV-based quantitative indices using an image analysis algorithm were applied to evaluate the postural control of 34 typically developed preschoolers. The effectiveness of the CV-based indices was investigated relative to current methods to explore the clinical applicability of the proposed method. The capacity of the CV-based indices to reflect therapists' qualitative evaluations was confirmed. Furthermore, compared to the conventional quantitative index, the CV-based indices provided more detailed quantitative information with lower costs. CV-based evaluations enable therapists to quantify details of motor performance that are currently observed qualitatively. The development of such precise quantification methods will improve the science and practice of occupational therapy and allow therapists to perform to their full potential.

Abstract
OBJECTIVE To compare the neuro-cognitive profiles among initial clinic referred medication naive sample of children with anxiety disorders (ANXs) and ADHD in a youth sample. METHOD Three groups of patients, ANX ( n = 40), ADHD ( n = 48), and ANX + ADHD ( n = 33), aged 7 to 12 years, were compared with respect to their Physical and Neurological Examination for Subtle Signs (PANESS) and cognitive measures (digit span, digit symbol, Trail Making Test [TMT]-A and TMT-B, Stroop test). RESULTS ADHD group performed worse than the other two groups with regard to soft signs and cognitive test performance; ANX + ADHD were impaired relative to ANX but better than ADHD. Significant differences were found for gait and station problems, overflows and timed movements, TMT error points, and Stroop interference scores. ADHD patients had more difficulty in warding off irrelevant responses and lower speed of time-limited movements. CONCLUSION This clinical evaluation study suggested that ANX and ADHD seem to have significantly different neuro-cognitive features: Poorest outcomes were observed among children with ADHD; rather than problems of attention, inhibitory control deficits were the most prominent differences between ANX and ADHD; and the presence of ANX appears to have mitigating effect on ADHD-related impairments.

Abstract
About 5~12% of school-aged children suffer from the Attention-Deficit/Hyperactivity Disorder (ADHD). However, the core mechanism of ADHD remains unclear. G protein-coupled receptor kinase-interacting protein-1 (GIT1) has recently been reported to be associated with ADHD in human and the genetic deletion of GIT1 result in ADHD-like behaviors in mice. Mice lacking GIT1 shows a shift in neuronal excitation/inhibition (E/I) balance. However, the pricise mechanism for E/I imbalance and the role of neuron-glia interaction in GIT1 knockout (KO) mice have not been studied. Especially, a possible contribution of glial GABA and tonic inhibition mediated by astrocytic GABA release in the mouse model for ADHD remains unexplored. Therefore, we investigated the changes in the amount of GABA and degree of tonic inhibition in GIT1 KO mice. We observed a decreased glial GABA intensity in GIT1 KO mice compared to wild type (WT) mice and an attenuation of tonic current from cerebellar granule cells in GIT1 KO mice. Our study identifies the previously unknown mechanism of reduced astrocytic GABA and tonic inhibition in GIT1 lacking mice as a potential cause of hyperactivity disorder.

Abstract
OBJECTIVE We aimed to assess disturbances in postural and gait balance and functional connectivity within the brain regions controlling balance in children with attention-deficit/hyperactivity disorder (ADHD). METHODS Thirteen children with ADHD and 13 age- and sex-matched controls were recruited. Gait balance was assessed by the difference in the center of pressure (COP) between the left and right foot, as well as the difference in plantar pressure between the left and right foot during gait. Neuroimaging data were acquired using a 3.0 Tesla MRI scanner. Functional connectivity between the vermis of the cerebellum and all other brain regionswas assessed. RESULTS The difference in plantar pressure between the left foot and right foot in the ADHD group was greater than that observed in the control group. The average COP jerk score of the right foot in the ADHD group was higher than that observed in the control group. A higher functional connectivity between the cerebellum and the right middle frontal gyrus (premotor cortex) and medial frontal gyrus (cingulate gyrus) was observed in the control group relative to the ADHD group. In the ADHD group, the difference in plantar pressure between the left and right foot was also negatively correlated with the beta-value within the middle frontal gyrus. CONCLUSION Children with ADHD had disturbance of balance as assessed by plantar pressure. Decreased brain connectivity from the cerebellum to the premotor cortex and anterior cingulate was associated with disturbances of posture and balance in children with ADHD.

Abstract
BACKGROUND Children with attention deficit/hyperactivity disorder (ADHD) frequently have motor problems. Previous studies have reported that the characteristic gait in children with ADHD is immature and that subjects demonstrate higher levels of variability in gait characteristics for the lower extremities than healthy controls. However, little is known about body movement during gait in children with ADHD. The purpose of this study was to identify the characteristic body movements associated with ADHD symptoms in children with ADHD. METHODS Using a three-dimensional motion analysis system, we compared gait variables in boys with ADHD (n = 19; mean age, 9.58 years) and boys with typical development (TD) (n = 21; mean age, 10.71 years) to determine the specific gait characteristics related to ADHD symptoms. We assessed spatiotemporal gait variables (i.e. speed, stride length, and cadence), and kinematic gait variables (i.e. angle of pelvis, hip, knee, and ankle) to measure body movement when walking at a self-selected pace. RESULTS In comparison with the TD group, the ADHD group demonstrated significantly higher values in cadence (t = 3.33, p = 0.002) and anterior pelvic angle (t = 3.08, p = 0.004). In multiple regression analysis, anterior pelvic angle was associated with the ADHD rating scale hyperactive/impulsive scores (β = 0.62, t = 2.58, p = 0.025), but not other psychiatric symptoms in the ADHD group. CONCLUSIONS Our results suggest that anterior pelvic angle represents a specific gait variable related to ADHD symptoms. Our kinematic findings could have potential implications for evaluating the body movement in boys with ADHD.

Abstract
BACKGROUND Attention-deficit hyperactivity disorder (ADHD) is linked to the presence of motor deficiencies, including balance deficits. The cerebellum serves as an integrative structure for balance control and is also involved in cognition, including timing and anticipatory regulation. Cerebellar development may be delayed in children and adolescents with ADHD, and inconsistent reaction time is commonly seen in ADHD. We hypothesized that dynamic balance deficits would be present in children with ADHD and they would correlate with attention and cerebellar functions. METHODS Sixty-two children with ADHD and no other neurological conditions and 62 typically developing (TD) children were examined with five trials of the Phyaction Balance Board, an electronic balancing platform. Cerebellar clinical symptoms were evaluated using an international ataxia rating scale. Conners' Continuous Performance Test was used to evaluate patterns of reaction. RESULTS Children with ADHD had poorer performance on balancing tasks, compared to TD children (P<0.001). They exhibited significantly greater sway amplitudes than TD children (P<0.001) in all of the five balancing trials. The effect size of the difference between the groups increased continuously from the first to the last trial. Balance score in both groups was related to the variation in the reaction time, including reaction time standard error (r =0.25; P=0.0409, respectively, r =0.31; P=0.0131) and Variability of Standard Error (r =0.28; P=0.0252, respectively, r =0.41; P<0.001). The burden of cerebellar symptoms was strongly related to balance performance in both groups (r =0.50, P<0.001; r =0.49, P=0.001). CONCLUSION This study showed that ADHD may be associated with poor dynamic balance control. Furthermore, we showed that maintaining balance correlates with neuropsychological measures of consistency of reaction time. Balance deficits and impaired cognitive functioning could reflect a common cerebellar dysfunction in ADHD children.
