Abstract: Goal-directed hand movements are guided by sensory information and may be adjusted ‘online’, during the movement. If the target of a movement unexpectedly changes position, trajectory corrections can be initiated in as little as 100ms in adults. This rapid visual online control is impaired in children with developmental coordination disorder (DCD), and potentially in other neurodevelopmental conditions. We investigated the visual control of hand movements in children in a ‘centre-out’ double-step reaching and grasping task, and examined how parameters of this visuomotor control co-vary with performance on standardised motor tests often used with typically and atypically developing children. Two groups of children aged 8-12 years were asked to reach and grasp an illuminated central ball on a vertically oriented board. On a proportion of trials, and at movement onset, the illumination switched unpredictably to one of four other balls in a centre-out configuration (left, right, up, or down). When the target moved, all but one of the children were able to correct their movements before reaching the initial target, at least on some trials, but the latencies to initiate these corrections were longer than those typically reported in the adult literature, ranging from 211 to 581 ms. These later corrections may be due to less developed motor skills in children, or to the increased cognitive and biomechanical complexity of switching movements in four directions. In the first group (n=187), reaching and grasping parameters significantly predicted standardised movement scores on the MABC-2, most strongly for the aiming and catching component. In the second group (n=85), these same parameters did not significantly predict scores on the DCDQ-07 parent questionnaire. Our reaching and grasping task provides a sensitive and continuous measure of movement skill that predicts scores on standardized movement tasks used to screen for DCD.

Abstract: To explore neurological factors affecting quality of life (QoL) in children and young people with ataxia-telangiectasia (A-T), from both child and parent perspective. 24 children/young people with A-T (mean age 11.2 ± 3.5 years 13 males) and 20 parents were recruited, and 58% were reassessed after an average interval of 3.4 years. Participants completed the PedsQL QoL assessment. Participants with A-T underwent structured neurological examination. QoL data from 20 healthy controls and their parents was used for comparison. Children/young people with A-T rated their QoL higher than parental ratings across time points, with no longitudinal change. Higher age of the child participant correlated with lower parental (r = -0.43, p = .008) but not child ratings of QoL (r = -0.16, p = .380). Child and parent QoL ratings from the A-T group were lower than respective ratings from controls (η Neurological disability does not determine child/young person QoL ratings in A-T. While certain aspects of neurological disability predict parent-proxy ratings, there is no decline in QoL over time. These results may reflect resilience in the face of a complex life-limiting disorder.

Abstract: Simulation is increasingly being used in healthcare improvement projects. The aims of such projects can be extremely erse. Accordingly, the outcomes or participant attributes that need to be measured can vary dramatically from project-to-project and may include a wide range of nontechnical skills, technical skills, and psychological constructs. Consequently, there is a growing need for simulation practitioners to be able to identify suitable measurement tools and incorporate them into their work. This article provides a practical introduction and guide to the key considerations for practitioners when selecting and using such tools. It also offers a substantial selection of ex le tools, both to illustrate the key considerations in relation to choosing a measure (including reliability and validity) and to serve as a convenient resource for those planning a study. By making well-informed choices, practitioners can improve the quality of the data they collect, and the likelihood that their projects will succeed.
