Abstract [en]

Introduction: Recent research proposes problems with action planning as part of atypical motor functioning in children with autism spectrum disorder (ASD), although findings are inconsistent. This study investigated relations between action planning and movement performance in 6-year-old children with and without ASD.

Patients and methods: 3D kinematic recordings of preferred arm/hand performance on a sequential peg rotation task with varying complexity of goal insertion (four endpoints and either visual or occluded goal display at onset) were conducted in 6 children with ASD (MAge = 6.4) and 6 typically developing (TD) controls (MAge = 6.5).

Results: Analyses revealed significant (p < .05) group and task-endpoint differences for movement segmentation (number of movement units, MUs) and 3D movement distance. Children with ASD generally displayed more MUs and longer distances than controls and all children showed increased MUs and movement distance on more complex task-endpoints. TD controls showed significantly shorter movement initiation latency (MIL) durations than ASD in the visual condition and evidently longer MILs in the occluded than visual condition. In contrast, no difference between goal display conditions was shown for the ASD group.

Conclusion: Children with ASD generally had longer movement distances and more segmented movements than controls, suggesting less efficient movement performance. Movement performance was not evidently affected by goal display condition in either group. However, the lack of MIL differences between goal display conditions within the ASD group indicates reduced pre-planning, possibly affecting movement execution efficiency.

Abstract [en]

This study explored age‐related differences in motor planning as expressed in arm‐hand kinematics during a sequential peg moving task with varying demands on goal insertion complexity (second‐order planning). The peg was a vertical cylinder with either a circular or semicircular base. The task was to transport the peg between two positions and rotate it various amounts horizontally before fitting into its final position. The amount of rotation required was either 0°, 90°, 180°, or −90°. The reaching for the peg, the displacement of it, and the way the rotation was accomplished was analyzed. Assessments of end state comfort, goal interpretation errors, and type of grip used were also included. Participants were two groups of typically developing children, one younger (Mage = 6.7 years) and one older (Mage = 10.3 years), and one adult group (Mage = 34.9 years). The children, particularly 6‐year‐olds, displayed less efficient prehensile movement organization than adults. Related to less efficient motor planning, 6‐year‐olds, mainly, had shorter reach‐to‐grasp onset latencies, higher velocities, and shorter time to peak velocities, and longer grasp durations than adults. Importantly, the adults rotated the peg during transport. In contrast, the children made corrective rotations after the hand had arrived at the goal.

Abstract [en]

This study investigated developmental changes and differences in upper-limb movement organization from 4 to 8 years of age in children born preterm (PT) and fullterm (FT). Kinematic recordings of precision-demanding unimanual movements and lateral assessments were carried out in 37 children (18 PT). All children, particularly children born PT, displayed considerable gain in movement kinematics. Contrary to controls, children born PT displayed persistently less-evident side preference. Gestational age (GA) contributed significantly to kinematic differences shown, with larger upper-limb deviances in the lowest GAs, in agreement with cross-sectional findings of altered hemispheric connections and delayed side-specialization among children born very PT.

Abstract [en]

Introduction: Recent research on sensory-motor skill in children with autism spectrum disorder (ASD) suggest that problems with planning sequential actions may explain difficulties with motor execution in this population. The present pilot study investigated upper-limb movement kinematics during a goal-directed manual task requiring sequential action planning in children with and without ASD at 6-7 years.

Patients and method: 3D kinematic recordings of performance with the preferred arm/hand during a sequential peg moving task with varying complexity of goal insertion (five endpoint conditions, open/revealed goal presentation) were carried out in 3 children with ASD (2 girls, mean age 6.3 years) and 3 typically developing children (3 girls, mean age 7 years). End state comfort and trial errors were also assessed.

Results: Preliminary analyses of whole movement spatiotemporal segmentation (movement units, MUs) at trial level revealed significant main effects for group and endpoint condition. Overall, children with ASD consistently performed less proficiently (more MUs) than controls for all conditions across hand/arm and head. Independent of group, all children displayed increased MUs for the more complex endpoints. Children with ASD also showed evidently poorer planning behavior (less end state comfort and increased trial errors) than controls.

Conclusion: Findings suggest difficulties with sequential movement planning in children with ASD in terms of suboptimal movement organization together with reduced end state comfort and inaccurate goal interpretations. In contrast to controls, children with ASD did not seem to have planned the onward action prior to action execution, contributing to the observed less proficient movement kinematics.

Abstract [en]

Although trainers and athletes consider “good timing skills” critical for optimal sport performance, little is known in regard to how sport-specific skills may benefit from timing training. Accordingly, this study investigated the effects of timing training on soccer skill performance and the associated changes in functional brain response in elite- and sub-elite female soccer players. Twenty-five players (mean age 19.5 years; active in the highest or second highest divisions in Sweden), were randomly assigned to either an experimental- or a control group. The experimental group (n = 12) was subjected to a 4-week program (12 sessions) of synchronized metronome training (SMT). We evaluated effects on accuracy and variability in a soccer cross-pass task. The associated brain response was captured by functional magnetic resonance imaging (fMRI) while watching videos with soccer-specific actions. SMT improved soccer cross-pass performance, with a significant increase in outcome accuracy, combined with a decrease in outcome variability. SMT further induced changes in the underlying brain response associated with observing a highly familiar soccer-specific action, denoted as decreased activation in the cerebellum post SMT. Finally, decreased cerebellar activation was associated with improved cross-pass performance and sensorimotor synchronization. These findings suggest a more efficient neural recruitment during action observation after SMT. To our knowledge, this is the first controlled study providing behavioral and neurophysiological evidence that timing training may positively influence soccer-skill, while strengthening the action-perception coupling via enhanced sensorimotor synchronization abilities, and thus influencing the underlying brain responses.

Abstract [en]

Altered white matter microstructure is commonly found in children born preterm (PT), especially those born at an extremely low gestational age (GA). These children also commonly show disturbed motor function. This study explores the relation between white matter alterations and upperlimb movement segmentation in 41 children born PT (19 girls), and 41 children born at term (18 girls) at 8 years. The PT group was subdivided into extremely PT (E-PT; GA = 25–27 weeks, N = 10), very PT (V-PT; GA = 28–32 weeks, N = 13), and moderately PT (M-PT; GA = 33–35 weeks, N = 18). Arm/hand preference (preferred/non-preferred) was determined through object interactions and the brain hemispheres were designated accordingly. White matter alterations were assessed using diffusion tensor imaging in nine areas, and movement segmentation of the body-parts head, shoulder, elbow, and wrist were registered during a unimanual goal-directed task. Increased movement segmentation was demonstrated consistently on the preferred side in the E-PT group compared with the term born group. Also compared with the term born peers, the E-PT group demonstrated reduced fractional anisotropy (FA) in the cerebral peduncle (targeting the corticospinal tract) in the hemisphere on the non-preferred side and in the splenium of corpus callosum. In contrast, in the anterior internal capsule on the preferred side, the E-PT group had increased FA. Lower FA in the cerebral peduncle, but higher FA in the anterior internal capsule, was associated with increased movement segmentation across body-parts in a contralateral manner. The results suggest that impaired development of sensorimotor tracts in E-PT children could explain a sub-optimal spatiotemporal organization of upper-limb movements.

Abstract [en]

INTRODUCTION: Neuro-motor impairments are commonly described in children born very preterm. Our purpose was to examine whether children born preterm differ concerning choice and amount of sport activities, laterality, and cognitive functioning in comparison to term born.

METHOD: A sample of 130 children, investigated at early school-age (mean = 7.8y); categorized into three groups based on gestational age (GA); 66 children term born (FT; GA 39 – 42w), 33 moderately preterm (M-PT; GA 34 – 36w), and 31 very preterm (V-PT; GA 23 – 33w). Sport activities were perceived from parents’ ratings; Activities scale/Child behavior checklist, Laterality Index (LI); by a modified Edinburgh Handedness inventory, and cognitive functioning by WISC-IV.

RESULTS: Children born M-PT performed comparable to FT, as regards to sport activities and cognitive performance. Children born V-PT had significantly poorer full scale IQ, lower sport performance, fewer sport activities, and participated in more individual sport activities in comparison to FT and M-PT. V-PT children were also less lateralized in comparison to FT and M-PT born.  Additionally, a significant positive correlation was found between LI and number of sport activities for the V-PT children, not found for the FT or M-PT.

CONCLUSUON: A very preterm birth seems to generate long-term effects on amount and choice of sport activities, side preference and cognitive functioning. Thus, more focus should be paid to children born very preterm to identify deviations in their early sport engagement and activities; consequently, to motivate and provide improvements in their sport activities, physical performance, and cognitive functioning.

Introduction: An increased knowledge of how the brain control finger movements give us keys to understand the recovery of motor function after a brain injury. This knowledge is crucial for the development of reliable and valid assessment methods in the clinical evaluation of hand function.

Research question: How are individual finger movements represented in the brain? Investigating the associations between kinematics and brain activity responses in healthy individuals.

Methods: Keeping the others still. Finger movements were performed lying in the MR scanner in order to register brain activity response during the task. Optoelectronic cameras simultaneously monitored the positions of reflective markers affixed to each finger. The marker position data were used to calculate each finger's movement frequency (MF),  movement independence (“Individuation Index”, II), stationary ability (Stationarity Index, SI)[1][1]. fMRI data was analyzed by contrasting the finger movements against its active rest.

Results: Preliminary analyses showed that (1) the finger movements primarily activate sensorimotor areas in the contralateral hemisphere (Fig. 1A), (2) that use of kinematic parameters in the fMRI analyses improved spatial specificity and (3) II engage a number of cortical areas, while MF engage fewer areas (Fig. 1B–D). Further analyses will further explore activations maps for each individual finger.

Discussion: The inclusion of movement parameters in the fMRI analyses improves the specificity in the derived activation map, increasing the interpretability of the neural correlates of movement control. This advancement carries the promise for the development of better assessment methods of the recovery of function post-stroke with usability in rehabilitation practices.

Abstract [en]

Background

Children born preterm (PT; <38 gestational weeks, GW) are frequently reported to have deviations in motor proficiency. Most studies use standardized test batteries to determine motor function in these children. Few studies have however examined the relations between test battery outcomes and outcomes from more detailed movement analysis.

Aim

To investigate associations between outcomes on the manual dexterity subtests from the Movement-ABC 2 with detailed 3D kinematic registrations during performance of a sensorimotor task with demands on fine motor skills and precision in school-aged children born PT and a comparison group born at full-term (FT).

Methods

As part of an ongoing quasi-longitudinal study, 7-8 year old children born PT (< 36 GW; n = 17) and an aged matched typically developing comparison group (n = 19) performed the M-ABC 2 and a fine motor task where 3D kinematic registration technique was applied. M-ABC 2 scaled scores from the manual dexterity index (MDI) were correlated with kinematic parameters sensitive to planning and on-line control (movement units, distance and speed). Differences between the PT and FT group were also analyzed.

Results

Preliminary analyses show no group differences on the outcomes from the 3D kinematic analyses but differences were evident on two (peg-board and follow-track) of the subtests constituting the MDI and the MDI where children born PT have lower scores than FT. For both groups but in different ways, within-group correlations show some associations between extracted kinematic properties and dexterity outcomes.

Conclusions

As the groups differed on the MDI outcomes it is surprising that none were found on the kinematic properties examined. Further, relatively few associations were found between the kinematic and M-ABC 2 outcomes. Investigation of the influence cognitive and executive functions have on these performances may offer explanations for this inconsistency
