• Single-subject research designs (SSRDs) preserve variability of individual responses to care, with designs and levels of evidence relative to robustness of experimental control and quality of implementation.
• N-of-1 trials (or other SSRDs) may be used to decide the best treatment protocol for an individual patient without bias.

• Event-related components show maturational changes from preschool to adolescence.
• Altered developmental trajectories are associated with atypical executive functioning.
• Event-related potentials can serve as biological markers for the development and dysfunction of executive skills.

• The first systematic review on dysphagia screening and evaluation tools in paediatric patients with neuromuscular diseases (NMD).
• In NMD there are alternatives to videofluoroscopic swallow study for dysphagia assessment.
• It highlights the need for additional studies of paediatric patients with NMD.

• Generally, raised intracranial pressure (RICP) predicts retinal haemorrhages after adjusting for age and aetiology.
• Specific intracranial pressure level (mmHg) was not correlated with retinal haemorrhage numbers.
• No evidence of new retinal haemorrhages during acute admission with RICP.
• Retinal haemorrhage–RICP association is different in inflicted traumatic brain injury compared with other aetiologies.

• Females with Rett syndrome were sedentary for most waking hours.
• Walking-based physical activity was mostly undertaken at slow cadences.
• Both adolescents and adults had more sedentary time than children.

• Sudden unexpected death in epilepsy is an important cause of mortality in patients with tuberous sclerosis complex (TSC).
• Patients with learning disabilities are at significantly greater risk of early mortality.
• Female patients are more vulnerable to renal and pulmonary disease compared with male patients.
• Less well-known manifestations of TSC, such as pancreatic malignancy, are important causes of death.

• Fidgety movement assessment (FMA) in infants born very preterm is practicable in a clinical setting.
• Clinical results of FMA are less robust than when performed in academic settings.
• A combination of FMA and cerebral ultrasound appears to improve prognostic information.
• FMA at 3 months can help to identify infants at risk for cognitive dysfunction.

• Hand–arm bimanual intensive therapy including lower extremity can be adapted for children with bilateral cerebral palsy (CP).
• Children demonstrate improvements in upper extremities, gross motor function, walking, and balance.
• They also demonstrate improvements in goal performance.
• Therapies based on motor skill learning are adaptable and efficient for children with bilateral CP.

• Dystonia is significantly related with all classifications, except the Communication Function Classification System (CFCS).
• Eating and Drinking Ability Classification System (EDACS) and Viking Speech Scale are significantly related with Gross Motor Function Classification System (GMFCS), Manual Ability Classification System (MACS), and CFCS.
• No significant relationship between choreoathetosis and classification scales at young age.
• Higher relationship between choreoathetosis and MACS and EDACS at older age.

• Further evidence of the stability of the Gross Motor Function Classification System (GMFCS) in children with cerebral palsy.
• More than half of the children received the same GMFCS rating at all assessments.

• Intrarater reproducibility for Eating and Drinking Ability Classification System (EDACS) is strong.
• Interrater reproducibility is fair, when classifying unfamiliar preschool children on a single videoed mealtime.
• EDACS classification is strongly related to the Gross Motor Function Classification System.
• EDACS classification is strongly related to standardized clinical feeding evaluation, suggesting strong construct validity.
• The EDACS is a viable classification of feeding ability in children with cerebral palsy.

• myTREEHOUSE is a population-specific assessment which offers a unique evaluation of self-concept.
• myTREEHOUSE is valid and reliable for children with cerebral palsy.

• The Health, Functioning and Wellbeing Summary helped families to gather and prioritize their thoughts before consultations.
• From the families’ perspectives, use of the tool improved communication during consultations.
• The tool ensured that the serious concerns of families were addressed during consultations.
