Measuring hip migration percentage in cerebral palsy using the HipScreen app.

Aims: Reimers migration percentage (MP) is a key measure to inform decision-making around the management of hip displacement in cerebral palsy (CP). The aim of this study is to assess validity and inter- and intra-rater reliability of a novel method of measuring MP using a smart phone app (HipScreen (HS) app). Methods: A total of 20 pelvis radiographs (40 hips) were used to measure MP by using the HS app. Measurements were performed by five different members of the multidisciplinary team, with varying levels of expertise in MP measurement. The same measurements were repeated two weeks later. A senior orthopaedic surgeon measured the MP on picture archiving and communication system (PACS) as the gold standard and repeated the measurements using HS app. Pearson's correlation coefficient (r) was used to compare PACS measurements and all HS app measurements and assess validity. Intraclass correlation coefficient (ICC) was used to assess intra- and inter-rater reliability. Results: All HS app measurements (from 5 raters at week 0 and week 2 and PACS rater) showed highly significant correlation with the PACS measurements (p < 0.001). Pearson's correlation coefficient (r) was constantly over 0.9, suggesting high validity. Correlation of all HS app measures from different raters to each other was significant with r > 0.874 and p < 0.001, which also confirms high validity. Both inter- and intra-rater reliability were excellent with ICC > 0.9. In a 95% confidence interval for repeated measurements, the deviation of each specific measurement was less than 4% MP for single measurer and 5% for different measurers. Conclusion: The HS app provides a valid method to measure hip MP in CP, with excellent inter- and intra-rater reliability across different medical and allied health specialties. This can be used in hip surveillance programmes by interdisciplinary measurers.

Developing the FEEDS toolkit of parent-delivered interventions for eating, drinking and swallowing difficulties in young children with neurodisability: findings from a Delphi survey and stakeholder consultation workshops.

BACKGROUND: Young children with neurodisability commonly experience eating, drinking and swallowing difficulties (EDSD). Little is documented about which interventions and outcomes are most appropriate for such children. We aimed to seek consensus between parents of children with neurodisability and health professionals on the appropriate interventions and outcomes to inform future clinical developments and research studies. METHODS: Two populations were sampled: parents of children aged up to 12 years with neurodisability who experienced EDSD; health professionals working with children and young people (aged 0-18 years) with neurodisability with experience of EDSD. Participants had taken part in a previous national survey and were invited to take part in a Delphi survey and/or consultation workshops. Two rounds of this Delphi survey sought agreement on the appropriate interventions and outcomes for use with children with neurodisability and EDSD. Two stakeholder consultation workshops were iterative, with the findings of the first discussed at the second, and conclusions reached. RESULTS: A total of 105 parents and 105 health professionals took part. Parents and health professionals viewed 19 interventions and 10 outcomes as essential. Interventions related to improvement in the physical aspects of a child's EDSD, behavioural changes of the child or parent, and changes in the child or family's well-being. Both parents and health professionals supported a 'toolkit' of interventions that they could use together in shared decision making to prioritise and implement timely interventions appropriate to the child. CONCLUSIONS: This study identified interventions viewed as essential to consider for improving EDSD in children with neurodisability. It also identified several key outcomes that are valued by parents and health professionals. The Focus on Early Eating, Drinking and Swallowing (FEEDS) Toolkit of interventions to improve EDSD in children with neurodisability has been developed and now requires evaluation regarding its use and effectiveness.

Neurodisability care in the time of COVID-19.

BACKGROUND: The COVID-19 pandemic resulted in an unprecedented societal and healthcare global crisis. Associated changes in regular healthcare provision and lifestyle through societal lockdown are likely to have affected clinical management and well-being of children/young people with neurodisability, who often require complex packages of multidisciplinary care. METHODS: We surveyed 108 families of children/young people with severe physical neurodisability and multiple comorbidities to understand how the pandemic had affected acute clinical status, routine healthcare provision, schooling and family mental and social well-being. RESULTS: A significant proportion of families reported missing hospital appointments and routine therapy, with subsequent worsening of symptoms and function. Families additionally described worsening stress and anxiety during the pandemic, regardless of their baseline level of socio-economic deprivation. CONCLUSION: This highlights the profound effect of the COVID-19 pandemic on health and function in young people with severe neurodisabilities and emphasizes the clear need to better understand how to support this vulnerable population moving forwards.

Location, symptoms, and management of plexiform neurofibromas in 127 children with neurofibromatosis 1, attending the National Complex Neurofibromatosis 1 service, 2018-2019.

We report on the location, symptoms, and management of plexiform neurofibroma (PN) in children with Neurofibromatosis Type 1 (NF1) attending the 2 National Complex Neurofibromatosis 1 Services at Guy's and St. Thomas' NHS Foundation Trust, London and St Mary's Hospital, Manchester. Retrospective data collection was performed from patient chart reviews from April 2018 to April 2019. There were 127 NF1 patients with PN, age range 0.8-17.0, mean age was 9.9 years (SD ± 4.2 years). The main location of the PN was craniofacial in 35%, and limb in 19%. Disfigurement was present in 57%, pain in 28%, impairment of function in 23%, and threat to function in 9% of children. Fifty-four percent of patients were managed conservatively, 28% surgically, and 19% are either taking or due to start a mitogen-activated protein kinase kinase (MEK) inhibitor (selumetinib or trametinib), either through a clinical trial or compassionate usage scheme. This national study provides a comprehensive overview of the management of children with PN in an era where new therapies (MEK inhibitors) are becoming more widely available. We anticipate that there will be a shift to more patients receiving MEK inhibitor therapy and combination therapy (surgery and MEK inhibitor) in the future.

Can wrist-worn devices and a smartphone application influence arm activity in children with unilateral cerebral palsy? A proof-of-concept study.

Aim: To determine whether a wrist-worn triaxial accelerometer-based device and software (including smartphone application), incorporating feedback, is feasible, acceptable, and can lead to increased affected upper limb use during everyday activities in children with unilateral cerebral palsy (UCP). Methods: Study design: Mixed methods proof of concept study. Participants: Children aged 8-18 years with UCP; age-matched typically developing controls ("Buddies"), therapists. Intervention: Baseline (2 weeks): devices recorded arm activity. Active feedback (6 weeks): devices also gave vibratory prompts if affected arm activity fell below pre-set personalised thresholds (UCP group only; control group continued as per Baseline). Final 2 weeks: as baseline. Both groups accessed a smartphone application providing feedback on relative arm motion throughout the study. Assessment and analysis: ABILHAND-Kids questionnaires and MACS classifications captured baseline participant characteristics (UCP group). Accelerometer data was used to calculate relative arm activity (signal vector magnitude) corrected for time worn/day, and trends in relative arm activity examined using single case experimental design (both groups). In-depth interviews with families, "Buddies" and therapists assessed feasibility and acceptability of implementation. A framework approach was used for qualitative data analysis. Results: We recruited 19 participants with UCP; 19 buddies; and 7 therapists. Five participants (two with UCP) did not complete the study. Baseline mean (stdev) ABILHAND-Kids score of children with UCP who completed the study was 65.7 (16.2); modal MACS score was II.Qualitative analysis demonstrated acceptability and feasibility of the approach. Active therapist input for this group was minimal. Therapists appreciated the potential for summary patient data to inform management. Arm activity in children with UCP increased in the hour following a prompt (mean effect size z = 0.261) for the non-dominant hand, and the dominant hand (z = 0.247). However, a significant increase in affected arm activity between baseline and intervention periods was not demonstrated. Discussion: Children with UCP were prepared to wear the wristband devices for prolonged periods. Whilst arm activity increased bilaterally in the hour following a prompt, increases were not sustained. Delivery of the study during the COVID-19 pandemic may have negatively influenced findings. Technological challenges occurred but could be overcome. Future testing should incorporate structured therapy input.

Care in COVID: A qualitative analysis of the impact of COVID-19 on the health and care of children and young people with severe physical neurodisability and their families.

AIM: To evaluate clinicians' perspectives on the impact of 'lockdown' during the COVID-19 pandemic for children and young people with severe physical neurodisability and their families. METHOD: Framework analysis of comments from families during a recent service review was used to code the themes discussed according to the World Health Organization International Classification of Functioning, Disability and Health (ICF) and interpreted into emergent themes to summarize the impact of lockdown (Stage 1). They were presented to a clinician focus group for discussion (consultants and physiotherapists working in a specialist motor disorders service, [Stage 2]). RESULTS: Three overarching themes 'Uncertainty and Anxiety', 'Exacerbation of Existing Inequalities' and 'Care Provision: Reaction, Adaptation, and Innovation' summed up the impact of the COVID-19 pandemic on health and well-being in children and young people with neurodisability and their families. All themes were influenced by time. INTERPRETATION: This study reflects clinician's perceptions of family experiences of the pandemic and lockdown. Significant impact is apparent in the entire U.K. population, but the complexity of care needs for children with physical neurodisability exacerbates this. Lobbying for government policy is vital to ensure that all children, and in particular those with significant health and social care needs, are protected and continue to access services. During the restoration and recovery phase of the pandemic, there is a need for service reconfiguration that utilizes what we have learned and is adaptive to individual family circumstances.

Parent-delivered interventions used at home to improve eating, drinking and swallowing in children with neurodisability: the FEEDS mixed-methods study.

BACKGROUND: Eating, drinking and swallowing difficulties are common in young children with neurodisability. These difficulties may lead to inadequate calorie intake, which affects a child's nutrition, growth and general physical health. OBJECTIVE: To examine which interventions are available that can be delivered at home by parents to improve eating, drinking and swallowing in young children with neurodisability and are suitable for investigation in pragmatic trials. DESIGN: This was a mixed-methods study that included focus groups, surveys, an update of published systematic reviews of interventions, a systematic review of measurement properties of existing tools, evidence mapping, evidence synthesis, a Delphi survey and stakeholder workshops. SETTING: The study was carried out in NHS hospitals, community services, family homes and schools. PARTICIPANTS: Parents of children who had neurodisability and eating, drinking and swallowing difficulties. Professionals from health and education. Young people with eating, drinking and swallowing difficulties or young people who had previously experienced eating, drinking and swallowing difficulties. DATA SOURCES: Literature reviews; national surveys of parents and professionals; focus groups with parents, young people and professionals; and stakeholder consultation workshops. REVIEW METHODS: An update of published systematic reviews of interventions (searched July-August 2017), a mapping review (searched October 2017) and a systematic review of measurement properties using COnsensus-based Standards for the Selection of health status Measurement INstruments (COSMIN) methodology (searched May 2018). RESULTS: Significant limitations of the available research evidence regarding interventions and tools to measure outcomes were identified. A total of 947 people participated: 400 parents, 475 health professionals, 62 education professionals and 10 young people. The survey showed the wide range of interventions recommended by NHS health professionals, with parents and professionals reporting variability in the provision of these interventions. Parents and professionals considered 19 interventions as relevant because they modified eating, drinking and swallowing difficulties. Parents and professionals considered 10 outcomes as important to measure (including Nutrition, Growth and Health/safety); young people agreed that these were important outcomes. Stakeholder consultation workshops identified that project conclusions and recommendations made sense, were meaningful and were valued by parents and professionals. Parents and health professionals were positive about a proposed Focus on Early Eating, Drinking and Swallowing (FEEDS) toolkit of interventions that, through shared decision-making, could be recommended by health professionals and delivered by families. LIMITATIONS: The national surveys included large numbers of parents and professionals but, as expected, these were not representative of the UK population of parents of children with eating, drinking and swallowing difficulties. Owing to the limitations of research evidence, pragmatic decisions were made about interventions that might be included in future research and outcomes that might be measured. For instance, the reviews of research found only weak or poor evidence to support the effectiveness of interventions. The review of outcome measures found only limited low-level evidence about their psychometric properties. CONCLUSIONS: Opportunities and challenges for conducting clinical trials of the effectiveness of the FEEDS toolkit of interventions are described. Parents and professionals thought that implementation of the toolkit as part of usual NHS practice was appropriate. However, this would first require the toolkit to be operationalised through development as a complex intervention, taking account of constituent interventions, delivery strategies, implementation and manualisation. Subsequently, an evaluation of its clinical effectiveness and cost-effectiveness could be undertaken using appropriate research methods. FUTURE WORK: Initial steps include FEEDS toolkit development and evaluation of its use in clinical practice, and identification of the most robust methods to measure valued outcomes, such as Nutrition and Growth.

Some young children with disabilities, such as those with cerebral palsy and autism spectrum disorder, have difficulties with eating, drinking and swallowing. Many strategies are employed to help with these difficulties (e.g. 'Positioning'), but we need to know more about which ones work best. We wanted to find out about the strategies parents use at home to help their children with eating, drinking and swallowing difficulties. We wanted to understand what is already known about the strategies that are available now and if children are getting the right help. We wanted to find out if doing more research would tell us which interventions work. We looked at what has been written about the ways in which parents help their child to eat, drink and swallow. We discussed this information with parents and health professionals. We developed a survey to ask what parent-delivered strategies are recommended by NHS professionals, which strategies parents use and how we would know if things had improved. We discussed the findings with parents and professionals. We then used a different type of survey. Parents and professionals were asked which strategies were most important and what they would most like to improve. We then held workshops to hear parents' and professionals' views on what we had found and to agree on how we would organise future research. We discussed some of the findings with young people. Research about these strategies and how to measure improvements in eating and drinking is of poor quality. A wide variety of strategies are used: 19 strategies were thought to be the most useful by parents and professionals. Parents and professionals agreed on 10 areas that they would most like to improve. Both groups thought that it was a good idea to have a 'toolkit' of strategies so that they could choose the right strategy at the right time.

Fifteen-minute consultation: A clinical approach to the management of the child with hypertonia.

Elevated tone (hypertonia) is a common problem seen in the paediatric clinic. For most children and young people, hypertonia is just one aspect of a broader disorder of movement and posture. This paper describes a clinical approach to the management of hypertonia in children, considering the contribution of high tone to the functional problems experienced by the child, the potential adverse effects of reducing tone, side effects of the intervention and the importance of setting objectives/goals for intervention which can be measured at follow-up. We describe this as the 'MOTOR' approach and provide some examples of how it can be used in practice.

Pharmacological management of abnormal tone and movement in cerebral palsy.

BACKGROUND: The evidence base to guide the pharmacological management of tone and abnormal movements in cerebral palsy (CP) is limited, as is an understanding of routine clinical practice in the UK. We aimed to establish details of motor phenotype and current pharmacological management of a representative cohort across a network of UK tertiary centres. METHODS: Prospective multicentre review of specialist motor disorder clinics at nine UK centres, collecting data on clinical features and pharmacological management of children and young people (CYP) with CP over a single calendar month. RESULTS: Data were collected from 275 CYP with CP reviewed over the calendar month of October 2017. Isolated dystonia or spasticity was infrequently seen, with a mixed picture of dystonia and spasticity ± choreoathetosis identified in 194/275 (70.5%) of CYP. A comorbid diagnosis of epilepsy was present in 103/275 (37.4%). The most commonly used medications for abnormal tone/movement were baclofen, trihexyphenidyl, gabapentin, diazepam and clonidine. Medication use appeared to be influenced separately by the presence of dystonia or spasticity. Botulinum toxin use was common (62.2%). A smaller proportion of children (12.4%) had undergone a previous neurosurgical procedure for tone/movement management. CONCLUSIONS: CYP with CP frequently present with a complex movement phenotype and comorbid epilepsy. They have multiple therapy, medical and surgical management regimens. Future trials of therapeutic, pharmacological or surgical interventions in this population must adequately encompass this complexity in order to be translatable to clinical practice.

Understanding frames: A qualitative exploration of standing frame use for young people with cerebral palsy in educational settings.

BACKGROUND: Consensus opinion supports standing frame use as part of postural management for nonambulant young people with cerebral palsy. Most young people with cerebral palsy in the United Kingdom, who use standing frames, use them at nursery or school, rather than at home. In this paper we report professionals' and parents' experiences and views of standing frame use specifically in educational settings. This research was conducted as part of a large mixed methods study to determine the acceptability and inform the design of a future trial of standing frames. METHODS: Qualitative methods were used: focus groups with educational professionals, parents and clinicians (paediatricians, physiotherapists and occupational therapists) were convened. Data were analysed thematically using framework analysis. RESULTS: Five focus groups were conducted. The overarching theme "flexibility" encompassed four subordinate themes: (i) "balancing education and therapy," which described the way education professionals had to juggle different priorities from health professionals within a multi-disciplinary team; (ii) "young people's autonomy," which highlighted participants' belief that standing frame use should be centred on the individual young person and their needs; (iii) "working within logistical boundaries," which demonstrated that "ideal" standing frame use was not always possible due to logistical issues (e.g., staffing and standing frame availability); and (iv) "competence and confidence," which highlighted that educational professionals felt that they lacked the training to confidently position young people in their standing frame. CONCLUSIONS: This paper highlights the complexity of standing frame use in the educational setting. If a standing frame programme is prescribed to be delivered in an educational setting, strong multidisciplinary and interagency communication is essential to balance therapy versus education. Training is required to ensure staff are competent in using the standing frame with the young person understanding their individual requirements. A flexible approach-inclusive of the young person's needs, logistical demands and resource-is necessary.

Fifteen-minute consultation: Modern-day art and science of managing cerebral palsy.

While there remains limited intervention to address the damage to the developing brain, current multidisciplinary management of cerebral palsy (CP) needs to minimise the impact of secondary musculoskeletal complications. A focus on comorbidities to maximise function for activity and participation by supporting the child and family in their environment is required. Comprehensive clinical guidance was published by National Institute for Health and Care Excellence (NICE) earlier this year. This article aims to provide a practical clinical approach to the child and family based on:(1) art: empathy, listening and weighing up the clinical picture of the child and family in context; diagnosis, the need for support and space; and care coordination at the right time; and (2) science: the current science in CP care is rapidly expanding in terms of plasticity, pathophysiology, functional assessments and treatments.

Fifteen-minute consultation: Management of the upper limb in unilateral cerebral palsy.

Children with unilateral cerebral palsy (UCP) have complex health, education and social care needs. Delayed gross motor milestones are the most common presenting feature, and much of the early management focuses on gross motor skills and lower limb management. In later childhood, adolescence and adulthood, upper limb function has significant impact on activity, participation and independence. There is clear pathophysiological rationale and emerging clinical evidence that earlier intervention to improve upper limb function is beneficial. Whereas most children with UCP are managed in secondary care, it is recommended that the assessment and delivery of specialist intervention for the upper limb occurs at a regional centre.

Standing frames for children with cerebral palsy: a mixed-methods feasibility study.

BACKGROUND: Standing frames are recommended as part of postural management for young people with cerebral palsy (CP) Gross Motor Function Classification System (GMFCS) level IV or V. They may have a variety of benefits, including improving bone mineral density, gastrointestinal function and social participation. The NHS needs to know if these benefits are real, given the cost implications of use and the reported negative effects (e.g. pain). The lack of evidence for the clinical effectiveness of standing frames demonstrates the need for evaluative research. OBJECTIVE(S): The aim of the study was to explore the acceptability of a future trial to determine the clinical effectiveness of standing frames. DESIGN: A sequential mixed-methods design was used. The findings of each stage informed the next stage. We conducted surveys, focus groups and in-depth interviews. PARTICIPANTS: Professionals who work with young people who use standing frames and parents who have a child who uses a standing frame took part in a survey of current standing frame practice (n = 551), a series of focus groups (seven focus groups, 49 participants in total) and a survey of research trial acceptability and feasibility (n = 585). Twelve young people who use a standing frame were interviewed. RESULTS: Standing frames were widely used as part of postural management for young people with CP both in school and at home but more frequently in school, and particularly by young people in primary school. Achieving the prescribed use was not always possible owing to resources, environment and family factors. Participation and activity engagement were important to young people. The majority of participants believed that standing frames research is necessary. Some reported concern that stopping standing frame use for a trial would cause irreversible damage. The maximum amount of time most health professionals and parents would agree to suspend standing frame use would be 12 weeks. LIMITATIONS: Owing to the nature of recruitment, we could not calculate response rates or determine non-response bias. Therefore, participants may not be representative of all standing frame users. CONCLUSIONS: Although parents and professionals who engaged in the qualitative aspect of this research and stakeholders who took part in the design workshops appreciated the lack of clinical evidence, our surveys, qualitative information and PPI demonstrated that most people had strong beliefs regarding the clinical effectiveness of standing frames. However, with key stakeholder engagement and careful planning, a trial would be acceptable. FUTURE WORK: We recommend a carefully planned trial that includes a pilot phase. The trial should evaluate the following question: 'does using a standing frame in school improve patient-reported outcomes of participation (primary outcome), quality of life, subjective well-being, body function and body structure (secondary outcomes) in young children (aged 4-11 years) with CP GMFCS III-V?'.

Drooling Reduction Intervention randomised trial (DRI): comparing the efficacy and acceptability of hyoscine patches and glycopyrronium liquid on drooling in children with neurodisability.

OBJECTIVE: Investigate whether hyoscine patch or glycopyrronium liquid is more effective and acceptable to treat drooling in children with neurodisability. DESIGN: Multicentre, single-blind, randomised controlled trial. SETTING: Recruitment through neurodisability teams; treatment by parents. PARTICIPANTS: Ninety children with neurodisability who had never received medication for drooling (55 boys, 35 girls; median age 4 years). EXCLUSION CRITERIA: medication contraindicated; in a trial that could affect drooling or management. INTERVENTION: Children were randomised to receive a hyoscine skin patch or glycopyrronium liquid. Dose was increased over 4 weeks to achieve optimum symptom control with minimal side-effects; steady dose then continued to 12 weeks. PRIMARY AND SECONDARY OUTCOMES: Primary outcome: Drooling Impact Scale (DIS) score at week-4. SECONDARY OUTCOMES: change in DIS scores over 12 weeks, Drooling Severity and Frequency Scale and Treatment Satisfaction Questionnaire for Medication; adverse events; children's perception about treatment. RESULTS: Both medications yielded clinically and statistically significant reductions in mean DIS at week-4 (25.0 (SD 22.2) for hyoscine and 26.6 (SD 16) for glycopyrronium). There was no significant difference in change in DIS scores between treatment groups. By week-12, 26/47 (55%) children starting treatment were receiving hyoscine compared with 31/38 (82%) on glycopyrronium. There was a 42% increased chance of being on treatment at week-12 for children randomised to glycopyrronium relative to hyoscine (1.42, 95% CI 1.04 to 1.95). CONCLUSIONS: Hyoscine and glycopyrronium are clinically effective in treating drooling in children with neurodisability. Hyoscine produced more problematic side effects leading to a greater chance of treatment cessation.
