RESUMO

AIMS: To investigate the accuracy of phenotypic early-onset ataxia (EOA) recognition among developmental conditions, including developmental coordination disorder (DCD) and hypotonia of central nervous system origin, and the effect of scientifically validated EOA features on changing phenotypic consensus. METHOD: We included 32 children (4-17y) diagnosed with EOA (n=11), DCD (n=10), and central hypotonia (n=11). Three paediatric neurologists independently assessed videotaped motor behaviour phenotypically and quantitatively (using the Scale for Assessment and Rating of Ataxia [SARA]). We determined: (1) phenotypic interobserver agreement and phenotypic homogeneity (percentage of phenotypes with full consensus by all three observers according to the underlying diagnosis); (2) SARA (sub)score profiles; and (3) the effect of three scientifically validated EOA features on phenotypic consensus. RESULTS: Phenotypic homogeneity occurred in 8 out of 11, 2 out of 10, and 1 out of 11 patients with EOA, DCD, and central hypotonia respectively. Homogeneous phenotypic discrimination of EOA from DCD and central hypotonia occurred in 16 out of 21 and 22 out of 22 patients respectively. Inhomogeneously discriminated EOA and DCD phenotypes (5 out of 21) revealed overlapping SARA scores with different SARA subscore profiles. After phenotypic reassessment with scientifically validated EOA features, phenotypic homogeneity changed from 16 to 18 patients. INTERPRETATION: In contrast to complete distinction between EOA and central hypotonia, the paediatric motor phenotype did not reliably distinguish between EOA and DCD. Reassessment with scientifically validated EOA features could contribute to a higher phenotypic consensus. Early-onset ataxia (EOA) and central hypotonia motor phenotypes were reliably distinguished. EOA and developmental coordination disorder (DCD) motor phenotypes were not reliably distinguished. The EOA and DCD phenotypes have different profiles of the Scale for Assessment and Rating of Ataxia.

RESUMO

Developmental Coordination Disorder (DCD) is considered to be abnormal motor skills learning, identified by clumsiness, slowness, and/or motor inaccuracy impairing the daily-life activities in all ages of life, in the absence of sensory, cognitive, or neurological deficits impairment. The present research focuses on studying DCD sleep structure and Cyclic Alternating Pattern (CAP) parameters with a full overnight polysomnography and to study the putative correlations between sleep architecture and CAP parameters with motor coordination skills. The study was a cross-sectional design involving 42 children (26M/16F; mean age 10.12 ± 1.98) selected as a DCD group compared with 79 children (49M/30F; mean age 9.94 ± 2.84) identified as typical (no-DCD) for motor ability and sleep macrostructural parameters according to the MABC-2 and polysomnographic (PSG) evaluations. The two groups (DCD and non-DCD) were similar for age (p = 0.715) and gender (p = 0.854). More significant differences in sleep architecture and CAP parameters were found between two groups and significant correlations were identified between sleep parameters and motor coordination skills in the study population. In conclusion, our data show relevant abnormalities in sleep structure of DCD children and suggest a role for rapid components of A phases on motor coordination development.

RESUMO

Children with Developmental Coordination Disorder (DCD) demonstrate inefficient motor planning ability with a tendency to opt for non-optimal planning strategies. Motor imagery can provide an insight to this planning inefficiency, as it may be a strategy for improving motor planning and thereby motor performance for those with DCD. In this study, we investigated the prevalence of end-state-comfort (ESC) and the minimal rotation strategy using a grip selection task in children with DCD with and without motor imagery instructions. Boys with (n = 14) and without DCD (n = 18) aged 7-12 years completed one, two and three colour sequences of a grip selection (octagon) task. Two conditions were examined; a Motor Planning (MP) condition requiring only the performance of the task and a Motor Imagery and Planning (MIP) condition, which included an instruction to imagine performing the movement before execution. For the MP condition, children with DCD ended fewer trials in ESC for the one (p = 0.001) and two colour (p = 0.002) sequences and used a minimal rotation strategy more often than those without DCD. For the MIP condition, the DCD group significantly increased their use of the ESC strategy for the one colour sequences (p = 0.014) while those without DCD improved for the two colour (p = 0.008) sequences. ESC level of the DCD group on the MIP condition was similar to those without DCD at baseline for all colour sequences. Motor imagery shows potential as a strategy for improving motor planning in children with DCD. Implications and limitations are discussed.

RESUMO

BACKGROUND: Evidence on anaerobic power and sprinting performance of children with Developmental Coordination Disorder (DCD) is limited. AIMS: The primary aim of this study was to investigate if the Children's Repetitive and Intermittent Sprinting Performance (CRISP) test could induce fatigue among participants. Secondly, the study examined the construct validity of the test in children with probable DCD (p-DCD) and typically developing (TD) peers. METHODS AND PROCEDURES: The study was carried out in two phases. In phase 1, we compared performance of 25 children (7-12 years) on the CRISP test to their performance on the Muscle Power Sprint test (MPST). For phase 2, forty-six (n = 46) participants with p-DCD were matched with TD children (n = 46) on age, weight and sex. Anaerobic performance of participants was assessed using the CRISP test, 10 × 5 m sprints straight and slalom tests, side jumps, stepping on platform task and the ladder agility test. OUTCOMES AND RESULTS: Phase 1: The increase in running time on the CRISP test was greater than on the MPST, indicating that the CRISP test was more fatiguing than the MPST. Phase 2: Children with p-DCD had poorer anaerobic capacity (muscle power, muscle endurance) compared to their TD peers. However, fatigue was comparable between the two groups. The differences in performance between p-DCD and TD children were found to be greater for tests with more agility elements. CONCLUSIONS AND IMPLICATIONS: The findings showed that CRISP test could induce fatigue in children. The CRISP test was also found to have positive construct (i.e. known-group) validity. The differences in muscle power and endurance between children with p-DCD and TD peers tend to widen when assessments are performed with tests having high agility components.

RESUMO

ABSTRACT This study aimed to make a systematic review of scientific articles on the planning of manual motor actions of typical and atypical children. To do so, a search of articles published between 1996 and 2017 was done on PubMed, LILACS, Science Direct, and SciElo databases. Original articles in English and Portuguese evaluating the planning of motor actions in typical and atypical children performing manual tasks were selected. For the analysis, the population age, number of children, type of task, main results, site of study and impact of the journal were considered. From the eighteen articles found, twelve were about typical children (from nine months old to twenty years old) and six about atypical children (from three to fourteen years old) diagnosed with autism, hemiplegic cerebral palsy, and developmental coordination disorders. In nine- to ten-year-old typical children, the planning ability of manual motor actions develops over the time and is similar to that of an adult. The atypical children showed motor planning ability lower than that of the typical children, and determining the age when this planning ability is acquired was not possible.


RESUMO O objetivo desse estudo foi realizar uma revisão sistemática de artigos científicos sobre o planejamento de ações motoras manuais de crianças típicas e atípicas. Para isso, foi feita uma busca de artigos publicados entre 1996 e 2017 nas bases de dados PubMed, Lilacs, Science Direct e SciELO. Foram incluídos artigos originais em língua inglesa e portuguesa, que avaliaram o planejamento de ações motoras em crianças típicas e atípicas por meio de tarefas manuais. Para a análise dos artigos, considerou-se a população, a faixa etária, o número de crianças, o tipo de tarefa, os principais resultados, o local de realização do estudo e o fator de impacto da revista. Ao todo, foram encontrados 18 artigos, sendo 12 com crianças típicas (9 meses a 20 anos de idade), e 6 com crianças atípicas (3 a 14 anos) diagnosticadas com autismo, paralisia cerebral hemiplégica e transtornos de déficit de coordenação. Nas crianças típicas, observa-se que a capacidade de planejamento de ações motoras manuais se desenvolve ao longo do tempo e se assemelha a de um adulto entre os 9 e 10 anos de idade. As crianças atípicas apresentaram capacidade de planejamento motor inferior à das crianças típicas e não foi possível determinar a idade em que essa habilidade de planejamento é estabelecida.

RESUMO

AIM: To examine cross-sectional differences in patterns of daily physical activity accumulation between preschool children at risk for developmental coordination disorder (DCD) compared to typically developing children. METHOD: In total, 514 children (292 males, 222 females; 4-5y) were recruited as part of the Coordination and Activity Tracking in CHildren (CATCH) study. Motor competence was assessed using the Movement Assessment Battery for Children, Second Edition; children scoring ≤5th centile comprised the probable DCD group (pDCD, n=87), between the 6th and 16th centile were considered to be at risk for DCD (rDCD, n=149), and >16th centile were considered typically developing (n=278). Seven-day physical activity was measured using hip-worn accelerometers. Average daily intensity of activity, frequency, and duration of moderate-to-vigorous physical activity (MVPA) bouts, and triaxial activity counts per minute were determined. RESULTS: No differences in daily activity in any intensity or axis of movement were found among the three groups. However, young children with pDCD accumulated their MVPA in slightly shorter bouts compared to typically developing children. INTERPRETATION: Young children at risk for DCD are not yet in an activity deficit. This may be because of the low motor skill demands of play in this age group. Early motor interventions may be able to promote continued physical activity participation in children with DCD. WHAT THIS PAPER ADDS: Preschool children at risk for developmental coordination disorder (DCD) are not less active than their peers. Overall intensity and frequency of daily activity bouts are similar among motor groups. Children with probable DCD accumulate their activity in shorter bouts.

RESUMO

Growing evidence from Alzheimer disease supports a potentially beneficial role of slow-wave sleep in neurodegeneration. However, the importance of slow-wave sleep in Parkinson disease is unknown. In 129 patients with Parkinson disease, we retrospectively tested whether sleep slow waves, objectively quantified with polysomnography, relate to longitudinal changes in Unified Parkinson's Disease Rating Scale motor scores. We found that higher accumulated power of sleep slow waves was associated with slower motor progression, particularly of axial motor symptoms, over a mean time of 4.6 ± 2.3 years. This preliminary finding suggests that deeper sleep relates to slower motor progression in Parkinson disease. Ann Neurol 2019;85:765-770.

RESUMO

INTRODUCTION: Psychomotor impairments in Autism Spectrum Disorders (ASD) have frequently been described in scientific literature. Such deficits impact upon the development of social motor function and interfere with the ability to adjust to everyday life. The inclusion of sensory-motor signs in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) confirms their importance in the diagnosis of ASD. Previous literature has shown the presence precocity of these signs, sometimes before the alteration of the social communication. To our knowledge, there are no existing clinical tools to measure sensory-psychomotor deficit, specifically in ASD. The current paper presents the construction and validation of a new scale, designed to evaluate sensory-psychomotor signs in Autism: 'the Sensory-psychomotor Particularities Scale in Autism' (SPSA). METHOD: The scale is composed of 160 items describing common sensory-psychomotor signs in autism. These items are grouped into 20 variables: touch, nociception, vestibular sensitivity, proprioceptive sensitivity, vision, auditory, multimodality, tone, posture, balance, global coordination, manual dexterity, body schema, bodily self-consciousness, relational adjustment, emotional expression, use of objects, space, time and tonico-emotional regulation. For each item, the psychomotor therapist evaluated sensori-psychomotor signs according to a five-level Likert scale (0="the sign is never expressed by the person", 1="weakly expressed", 2="moderately expressed", 3="severely expressed" and 4="the sign is very characteristic of the person and very severely expressed"). This is completed by a family interview in order to assess the impact of these signs on everyday situations. The study included 111 children with autism. The presence of neurological and genetic diseases was exclusion criteria. For each child, a global developmental evaluation was carried out by an expert clinical team specializing in ASD. Standardized clinical tools were used: Autism Diagnostic Observation Schedule (ADOS), Childhood Autism Rating Scale (CARS), Behavior Summarized Evaluation scale (BSE-R), Repeated and Restricted Behavior scale (RRB), Movement Assessment Battery for Children (M-ABC), Motor Development Rating scale (MDR), Sensory Profile (SP). Developmental quotients (DQ) were evaluated using various tests depending on age and ability. RESULTS: Factor analysis produced three clinically relevant factors: F1: "sensory-emotional synchronization", F2: "multisensory integration" and F3: "motor skills": each containing a similar quantity of items. They account for roughly equal percentages of variance (18.9%, 18.0%, 16.8%, respectively). The factorial structure does not change if the 26 children with comorbid developmental coordination disorder are removed. The three factors show good internal consistency and excellent inter-rater reliability. F1 is comprised of 6 items: touch, nociception, proprioceptive sensitivity, vision, emotional expression and tonico-emotional regulation. This factor is significantly associated with items of the Sensory Profile (touch processing, poor registration, sensory seeking). F2 is comprised of 5 items: multimodality, bodily self-consciousness, relational adjustment, use of objects and space. This factor is associated with ADOS, BSE-R and RRB scores, and the item "touch processing" of the Sensory Profile. F3 is comprised of 4 items: tone, posture, global coordination, manual dexterity. This factor is associated with the M-ABC, the MDR and the item "low endurance" of the Sensory Profile. CONCLUSION: The SPSA is a relevant clinical tool to assess the severity of sensory-psychomotor clinical signs in order to describe the individual profiles of children with ASD. It represents a critical step in advancing knowledge of the complex and heterogeneous pattern of psychomotor development in autism. It could make a valuable contribution to the field, both in research and clinical practice.

RESUMO

BACKGROUND: Children with developmental coordination disorder (DCD) have lower physical activity (PA) than children with typical development (TD). PA and fundamental movement skills (FMS) are positively associated so interventions that promote FMS of children with DCD are recommended. AIM: To examine the effects of a school-based FMS training program on motor functions, PA and other psychological outcomes. METHODS AND PROCEDURES: A total of 131 primary children were allocated to FMS training groups (DCD-FMS n = 35, TD-FMS n = 29), which received FMS training (eight weekly 40-min sessions), or to control groups (DCD-C n = 34, TD-C n = 33), which received conventional physical education lessons. Outcome measures, including accelerometer-assessed PA, motor functions, and self-perceived competence and enjoyment, were measured at baseline, 1-week (immediate effect), 3-months (short-term effect) and 12-months (longer-term effect) after the intervention. OUTCOMES AND RESULTS: FMS training resulted in improved FMS proficiency and increased PA and enjoyment of activity participation in children. In particular, the DCD-FMS group reported greater enjoyment over time. Some effects were also evident for both short- and longer-term. CONCLUSIONS AND IMPLICATIONS: The findings suggest that a school-based FMS training program has the potential to promote physical and psychological health in children with DCD in the long run.

RESUMO

OBJECTIVE: The primary aim of this meta-analysis was to evaluate the effects of repetitive transcranial magnetic stimulation (rTMS) on limb movement recovery post-stroke and cortex excitability, to explore the optimal parameters of rTMS and suitable stroke population. Second, adverse events were also included. DATA SOURCES: The databases of PubMed, EBSCO, MEDLINE, the Cochrane Central Register of Controlled Trials, EBM Reviews-Cochrane Database, the Chinese National Knowledge Infrastructure, and the Chinese Science and Technology Journals Database were searched for randomized controlled trials exploring the effects of rTMS on limb motor function recovery post-stroke before December 2018. REVIEW METHODS: The effect sizes of rTMS on limb motor recovery, the effect size of rTMS stimulation parameters, and different stroke population were summarized by calculating the standardized mean difference (SMD) and the 95% confidence interval using fixed/random effect models as appropriate. RESULTS: For the motor function assessment, 42 eligible studies involving 1168 stroke patients were identified. The summary effect size indicated that rTMS had positive effects on limb motor recovery (SMD = 0.50, P < 0.00001) and activities of daily living (SMD = 0.82, P < 0.00001), and motor-evoked potentials of the stimulated hemisphere differed according to the stimulation frequency, that is, the high-frequency group (SMD = 0.57, P = 0.0006), except the low-frequency group (SMD = -0.27, P = 0.05). No significant differences were observed among the stimulation parameter subgroups except for the sessions subgroup ( P = 0.02). Only 10 included articles reported transient mild discomfort after rTMS. CONCLUSIONS: rTMS promoted the recovery of limb motor function and changed the cortex excitability. rTMS may be better for early and pure subcortical stroke patients. Regarding different stimulation parameters, the number of stimulation sessions has an impact on the effect of rTMS.

RESUMO

This is the first review to quantitatively summarise evidence evaluating MI functioning in children with DCD compared to controls based on the hand rotation task (HRT). Specifically, MI performance was assessed using three different behavioural performance measures on the HRT (i.e., reaction time, accuracy and efficiency). Eight studies were included for quantitative analysis, yielding data for 176 and 198 children with and without DCD respectively. While children with DCD consistently used MI across all measures of the task, they continually demonstrated reductions in HRT performance relative to controls. Additionally, group differences appeared to be strongest and more commonly detected when using the IES (mean inverse efficiency-IES) metric on the HRT. These effects did not differ statistically as a function of instruction type. In support of the internal modelling deficit hypothesis, group effects suggested children with DCD demonstrate broad reductions in HRT performance relative to controls. However, consideration of effect size and study level analysis showed the ability for an individual study to detect these effects differs considerably depending on the outcome metric adopted.

RESUMO

OBJECTIVE: This study aimed to evaluate the effectiveness of Kinesio tape (KT) on lower limb muscle activation pattern in children with developmental coordination disorder (DCD) during walking. DESIGN: A parallel-group randomized controlled trial. SETTING: University laboratory setting. PARTICIPANTS: Twenty-five children with DCD were randomly allocated to the KT group (mean age = 7.97 years) and 24 to the control group (mean age = 8.04 years). INTERVENTION: KT group received KT application to the quadriceps and gastrocnemius muscles whereas the control group received no intervention. MEASUREMENTS: Peak muscle activation (in percentage of maximal voluntary isometric contraction [%MVIC]) in the lower limbs during gait was measured by means of surface electromyography, electrogoniometry, and foot contact switches. RESULTS: Gastrocnemius medialis activation during mid stance (23.46%MVIC, 95% CI = -32.53, -14.39) and late stance phases (3.25%MVIC, 95% CI = -5.67, -0.81) of gait increased after the application of KT in the KT group compared to baseline values. The KT group demonstrated 26.87%MVIC (95% CI = 26.87, 7.11) higher gastrocnemius medialis muscle peak activation during mid stance phase at post-test when compared with the control group. Moreover, gastrocnemius medialis and biceps femoris muscle peak activation during loading response decreased by 8.36%MVIC (95% CI = 2.71, 14.02) and 3.54%MVIC (95% CI = 1.08, 6.01), respectively, in the control group overtime. CONCLUSIONS: The application of KT on children with DCD had an increased gastrocnemius medialis muscle activation during stance phase. KT could be incorporated into gait re-education programmes to facilitate muscle contraction in these children.

RESUMO

AIM: The aim of this study is to describe the course of motor development in children with Dravet syndrome. METHOD: Forty-three participants (21 males, 22 females; mean age at last assessment 53.89mo±42.50mo) met the inclusion criteria of having a confirmed diagnosis of Dravet syndrome and presence of data on motor development. All data between 1985 and 2018 were derived retrospectively from their medical records. Gross motor milestones and motor age equivalents were used to describe motor development. Standardized neurodevelopmental assessment and the Bayley Scales of Infant Development defined the overall motor development. Peabody Developmental Motor Scales, Bruininks-Oseretsky Test of Motor Proficiency, and the Beery-Buktenica Developmental Test of Visual-Motor Integration were used to describe development in specific motor domains. RESULTS: Children with Dravet syndrome showed a delay in both sitting (seven out of 14) and walking independently (11 out of 25). Overall motor age equivalents revealed a delay in 29 out of 38 assessments (age 9-115mo). All assessments of children older than 2 years (16 out of 16) showed a delay. Gross motor delay was present in seven out of seven and fine motor delay in 10 out of 13 assessments (age 19-167mo). INTERPRETATION: Motor development is delayed in the majority of children with Dravet syndrome older than 2 years and increases with age. WHAT THIS PAPER ADDS: A delay in motor development is present in most children with Dravet syndrome older than 2 years. Large diversity in early gross motor milestones confirms heterogeneity in Dravet syndrome.

RESUMO

OBJECTIVES:: To investigate the feasibility and potential efficacy of a six-week interactive computer play training on balance and gross motor function in children with moderate cerebral palsy. DESIGN:: A pilot single-blinded matched randomized controlled study. SETTING:: Community. PARTICIPANTS:: In total, 18 children with moderate cerebral palsy were recruited, paired according to age and severity of cerebral palsy and randomized into intervention group or control group. INTERVENTION:: The intervention group received additional trunk control training using the interactive computer play in sitting four times per week, 20 minutes per session for six weeks. All study children continued their usual physiotherapy programme. MEASUREMENTS:: All study children were assessed at baseline, week 3, week 6 (completion of intervention) and week 12 using the Pediatric Reach Test, Gross Motor Function Measure-66-Item Set and 2-Minute Walk Test. RESULTS:: All intervention children completed and enjoyed the training with no reported adverse event. All children were assessed at all time points. No significant difference was found between the two groups in all assessments. In both groups of children, significant improvements were found in the Gross Motor Function Measure-66-Item Set between week 3 (intervention group: mean 53.41, SD 5.34; control group: mean 52.86, SD 8.33) and week 6 (intervention group: mean 55.00, SD 6.32; control group: mean 54.20, SD 8.35). CONCLUSION:: The intervention protocol of a six-week interactive computer play training was feasible and safe for children with moderate cerebral palsy in special school settings. Future studies with larger sample sizes or using single-subject designs are recommended.

RESUMO

OBJECTIVE: This study investigated the relationship between motor and cognitive/language development in children with Down syndrome (DS). We also tested the hypothesis that acquisition of walking skills facilitates later cognitive/language development. METHODS: Participants were 156 children with DS who were less than 48 months old and had undergone a health checkup by medical doctors and received rehabilitation treatment between April 2013 and March 2017 in Yokohama, Japan. To assess their development, the Kyoto Scale of Psychological Development (KSPD) 2001 was used, which measures development in three subdomains: Posture-Motor (P-M), Cognitive-Adaptive (C-A), and Language-Social (L-S). To investigate the relationship between motor and cognitive/language development, partial correlation analyses were conducted that controlled for participants' age. To test the effect of achieving walking skills, regression analyses were conducted using only data from participants who took the KSPD at least twice and could not walk at the initial test. RESULTS: P-M developmental age (DA) was significantly and positively correlated with both C-A DA and L-S DA in children 1-3 years old. The relationship strengthened with increased age. Acquisition of walking skills had a significant positive effect on both the C-A DA and L-S DA at the second test when controlling for the C-A DA and L-S DA at the first test and age at the second test. CONCLUSION: Motor development was correlated with both cognitive and language development in young children with DS. Results also suggested that achievement of walking could facilitate later cognitive/language development in children with DS.

RESUMO

OBJECTIVE:: To evaluate the effects of an intervention based on a specific set of goals on goal attainment, manual dexterity, hand grip strength and finger prehension force compared to a standardized approach in patients with Parkinson's disease. DESIGN:: Randomized controlled trial. SETTING:: Home-based. PARTICIPANTS:: Fifty patients with a clinical diagnosis of Parkinson's disease acknowledging impaired manual ability were randomized into two groups. INTERVENTIONS:: Patients in the experimental group ( n = 25) were included in an intervention focused on task components that involved goals proposed by participants. Patients in the control group ( n = 25) received a standard intervention focused on impairments in range of motion, grasp and manipulation. Home condition and duration (four weeks, twice a week) were similar in both groups. MAIN OUTCOME MEASURES:: The primary outcome measure was goal achievement assessed with the Goal Attainment Scaling. Secondary outcomes were manual dexterity evaluated with the Purdue Pegboard Test and hand grip strength and finger prehension force assessed using a dynamometer. RESULTS:: After four weeks, significant between-group improvement in goal attainment was observed in the experimental group (change 17.36 ± 7.48 vs. 4.03 ± 6.43, P < 0.001). Compared to the control group, the experimental group also showed a significant improvement ( P < 0.05) in manual dexterity (postintervention values in the most affected arm 10.55 ± 1.95 vs. 7.33 ± 3.63 pins, P < 0.001) and finger prehension force (postintervention values in the most affected arm 8.03 ± 1.93 vs. 6.31 ± 1.85 kg, P = 0.010). CONCLUSIONS:: Targeting therapy toward specific goals leads to greater changes in arm function than a standardized approach in people with Parkinson's disease.

RESUMO

BACKGROUND: Practitioners often assess the motor skills of children presented with suspected developmental delays. It is essential that the tests used to assess children have strong measurement properties including validity. AIM: The structural validity of the Bruininks-Oseretsky Test of Motor Proficiency - second edition Brief Form (BOT-2-BF) was investigated. METHOD: 123 healthy children (67 males & 56 females; M = 10 years, 2 months; SD = 1 year, 4 months) completed the BOT-2-BF. The Rasch Measurement Model (RMM) was used to assess the 14-item BOT-2-BF's dimensionality, hierarchical ordering, differential item functioning (DIF), and item and person separation reliability. RESULTS: Nine BOT-2-BF misfit RMM requirements. A second RMM analysis of a five-item BOT-2-BF version was completed. The five-item version did meet the RMM requirements of item fit, dimensionality, hierarchical ordering, lack of DIF, and adequate item and person separation reliability. IMPLICATIONS: The 14-item version of the BOT-2-BF is not recommended for use as a screening scale to assess children's motor skill performance. However, a revised five-item version of the BOT-2-BF did appear to meet RMM expectations. Further psychometric assessment of the revised five-item version of the BOT-2-BF is recommended.

RESUMO

BACKGROUND: Autism Spectrum Disorder (ASD) and Developmental Coordination Disorder (DCD) are developmental disorders with distinct definitions and symptoms. However, both conditions share difficulties with motor skills, including impairments in postural control. While studies have explored postural sway variables in children with DCD and ASD as compared to typical development (TD), few have used kinematic data to assess the magnitude of differences between these two neurodevelopmental conditions. There are few sensitive and specific measures available to assess balance impairment severity in these populations. RESEARCH QUESTION: Do individuals with ASD, DCD, and TD differ in dynamic postural control? METHODS: We quantified postural control differences between ASD, DCD, and TD during a dynamic balance task. 10 ASD, 10 DCD, and 8 TD agematched children completed a dynamic postural control task in a virtual environment. They leaned to shift their center of pressure (CoP) to match a user-controlled object to an oscillating target (0.1 Hz-0.8 Hz). RESULTS: The DCD group had higher CoP accelerations compared to ASD or TD. While the DCD and TD groups did not differ in their medial-lateral velocity, the ASD group had low medial-lateral velocity and acceleration as compared to DCD and TD. ASD group velocity and acceleration did not differ from that of the TD group in the anterior-posterior direction. Higher accelerations in the DCD group reflected non-fluid movements; by contrast, the ASD group had slower, more fluid movements. Results may reflect differences in how children with ASD and DCD plan, execute, and modify motor actions. SIGNIFICANCE: This study demonstrates the potential utility of CoP acceleration and velocity as a sensitive and specific means of differentiating between ASD, DCD, and TD. Results indicating group differences between ASD and DCD in velocity and acceleration profiles represent an important step toward understanding how these populations modify motor plans during dynamic tasks.

RESUMO

Discrete and rhythmic movements are two fundamental motor primitives being, at least partially, controlled by separate neural circuitries. After a stroke, both primitives may be impaired in the upper limb. Currently, intensive functional movement therapy is recommended after stroke, but it is mainly composed of discrete movements. No recommendation is made for the specific training of rhythmic movements. However, if they form two different primitives, both should receive a specific training to recover the complete motor repertoire, as many daily live movements integrate both of them. This paper reports the effects of a pure unilateral rhythmic movement therapy on motor performance, after stroke. Thirteen patients with chronic stroke participated in this longitudinal pilot study. They were assessed twice before the therapy to validate their chronic state, and twice after the last session to establish the short-term and long-term effects of the therapy. The therapy itself was composed of 12 sessions spread over 1 month. The exercises consisted in performing straight or circular rhythmic movements, while receiving assistance as need through a robotic device. Short-term and long-term improvements were observed in rhythmic movements regarding smoothness, velocity, and harmonicity. More surprisingly, some transfer occurred to the untrained discrete movements. This finding disputes previous studies that reported no transfer from rhythmic to discrete movements with healthy participants.
