Health-related quality of life in 205 children with arthrogryposis multiplex congenita.

PURPOSE: Arthrogryposis multiplex congenita (AMC) describes a heterogeneous group of rare congenital conditions. Health-related quality of life (HRQL) may be reduced in AMC due to broadly heterogeneous physical impairments and participation limitations. This study described HRQL in children and youth with AMC, compared HRQL between child self- and parent-proxy reports, and identified factors associated with better/worse HRQL. METHODS: Data on 205 children with AMC (age 8-21 years) from a North American AMC registry across eight hospital sites was used. HRQL was assessed cross-sectionally using the Patient Reported Outcome Measurement Information System (PROMIS) and European Quality of Life-5 Dimensions-Youth-3 Levels (EQ-5D-Y-3 L) by self-report, parent proxy-report or both. RESULTS: Mean child-reported PROMIS T-scores were significantly lower than the normal mean for the Upper Extremity (mean = 33.0) and Mobility (mean = 37.2) but in the normal range for Pain Interference (mean = 46.6) and Peer Relationships (mean = 51.7). A lot of problems in EQ-5D-Y-3 L was reported by 37% in Feeling Worried/ Sad/ Unhappy, 46% in Having Pain/Discomfort, 50% in Doing Usual Activities, 56% in Mobility, and 57% in Looking After Myself. Compared to child-report, parents reported significantly worse PROMIS T-scores and higher problems in EQ-5D domains. Wheelchair use, being small for gestational age, prolonged hospitalization after birth, increased number of orthopedic surgeries, and caregiver's stress were associated with lower HRQL scores. CONCLUSION: Findings indicate the importance of considering both the child's and parents' reports of HRQL, and to provide multimodal interventions that focus on the effect of childhood and parental characteristics to promote HRQL among children with AMC.

Our study describes health aspects of quality of life (HRQL) in a large sample of children with arthrogryposis multiplex congenita (AMC). Information on HRQL is crucial for clinicians treating AMC to improve treatment outcomes, and for individuals with AMC and their families to understand various aspects of life in AMC. Our results showed that most children with AMC have mild to moderate problems in mobility (e.g., getting around, walking), self-care (e.g., taking shower), and doing usual activities. We found that the parents tend to perceive worsened HRQL for the child with AMC. Our findings also showed that children who had low birthweight for gestational age, were hospitalized for prolonged periods as an infant, had multiple orthopedic surgeries, and use a wheelchair are more likely to have lower HRQL. Children who have a parent who expressed high caretaking stress tend to have lower mobility and physical functioning. Our findings will help develop more personalized care plans for children with AMC considering various individual and familial characteristics.

Evidence-based early rehabilitation for children with cerebral palsy: co-development of a multifaceted knowledge translation strategy for rehabilitation professionals.

Background: Cerebral palsy (CP) is the most common childhood physical disability. Early and evidence-based rehabilitation is essential for improving functional outcomes in children with CP. However, rehabilitation professionals face barriers to adopting evidence-based practices (EBP)s. The objective of this project is to develop a knowledge translation (KT) strategy to support CP-EBP among pediatric rehabilitation professionals. Methods: We follow an integrated KT approach by collaborating with clinician- and patient-partners. Partners engaged in co-design through team meetings and content review via email. The KT strategy comprises two components: (1) An electronic (e)-KT toolkit was created from summarized evidence extracted from randomized clinical trials on early rehabilitation for children with CP, and (2) a multifaceted online KT training program developed with guidance from a scoping review exploring effective KT strategies. Results: The e-KT toolkit summarizes twenty-two early interventions for children with or at risk for CP aged 0-5 years. Each module features an introduction, resources, parent/family section, and clinician information, including outcomes, intervention effectiveness, and evidence level. The KT training program includes three 10-15 min video-based training modules, text summaries, quizzes, and case studies. Site champions, identified as qualified rehabilitation professionals, were onboarded to support the site implementation of the training program. A champion-training booklet and 1-hour session were designed to equip them with the necessary knowledge/resources. Conclusion: The tailored, multifaceted, and co-designed KT strategy aims to be implemented in pediatric rehabilitation sites to support professional's uptake of CP-EBPs. Lessons learned from its development, including the co-development process and multifaceted nature, hold potential for broader applications in rehabilitation.

Pediatric Performance-Based Outcome Measures for Upper Extremity Function: A Scoping Review and Linking to the International Classification of Functioning, Disability, and Health.

Background. Performance-based outcome measures (PBOMs) are objective measures that assess physical capacity or performance in specific tasks or movements. Purpose. 1) to identify which PBOMs are most frequently reported to evaluate upper extremity (UE) function in pediatric rehabilitation 2) to determine the link between constructs of the ICF and meaningful concepts extracted from each identified PBOM. Methods. Pediatric UE PBOMs were searched in four databases. The selection of outcome measures included an initial title and abstract screening, followed by full-text review of the articles to be included based on identified selection criteria. Two reviewers were appointed to link the meaningful concepts identified in the outcome measures independently and a third reviewer was consulted in case of ambiguity to make a final decision. Findings. After the initial screening, 1786 full-text articles were reviewed, 1191 met the inclusion criteria, in which 77 outcome measures were identified and 32 were included in the linking process. From the included 32 outcome measures, 538 items were extracted and linked to the ICF. The most commonly cited measures included Assisting Hand Assessment, Jebsen-Taylor Hand Function Test, Melbourne Assessment of Unilateral Upper Limb. The Activity and Participation domain represented 364 codes followed by the Body Functions domain domain which represented 174 codes. Implications. A majority of the outcome measures identified were linked with the Mobility, Fine Hand Use of the ICF. Therefore, when selecting a PBOM, careful considerations need to be made regarding which concept of health is to be assessed.

Common data elements for arthrogryposis multiplex congenita: An international framework.

AIM: To facilitate multisite studies and international clinical research, this study aimed to identify consensus-based, standardized common data elements (CDEs) for arthrogryposis multiplex congenita (AMC). METHOD: A mixed-methods study comprising of several focus group discussions and three rounds of modified Delphi surveys to achieve consensus using two tiered-rating scales were conducted. RESULTS: Overall, 45 clinical experts and adults with lived experience (including 12 members of an AMC consortium) participated in this study from 11 countries in North America, Europe, and Australia. The CDEs include 321 data elements and 19 standardized measures across various domains from fetal development to adulthood. Data elements pertaining to AMC phenotypic traits were mapped according to the Human Phenotype Ontology. A universal governance structure, local operating protocols, and sustainability plans were identified as the main facilitators, whereas limited capacity for data sharing and the need for a federated informatics infrastructure were the main barriers. INTERPRETATION: Collection of systematic data on AMC using CDEs will allow investigations on etiological pathways, describe epidemiological profile, and establish genotype-phenotype correlations in a standardized manner. The proposed CDEs will facilitate international multidisciplinary collaborations by improving large-scale studies and opportunities for data sharing, knowledge translation, and dissemination.

Arthrogryposis multiplex congenita: dental and maxillofacial phenotype - A scoping review.

INTRODUCTION: Arthrogryposis multiplex congenita (AMC) is a heterogeneous group of disorders associated with decreased fetal movement, with a prevalence between 1/3000 and 1/5200 live births. Typical features of AMC include multiple joint contractures present at birth, and can affect all joints of the body, from the jaw, and involving the upper limbs, lower limbs and spine. The jaws may be affected in 25 % of individuals with AMC, with limited jaw movement and mouth opening. Other oral and maxillofacial deformities may be present in AMC, including cleft palate, micrognathia, periodontitis and delayed teething. To our knowledge, oral and maxillofacial abnormalities have not been systematically assessed in individuals with AMC. Therefore, this scoping review was conducted to identify, collect, and describe a comprehensive map of the existing knowledge on dental and maxillofacial involvement in individuals with AMC. METHODOLOGY: A scoping review was conducted in accordance with the Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews guidelines. The PRISMA guidelines for scoping reviews were followed and databases were searched for empirical articles in English and French published until October 2022. We searched MEDLINE, Embase, Web of Science and ERIC databases. Two authors independently reviewed the articles and extracted the data. RESULTS: Of a total of 997 studies that were identified, 96 met the inclusion criteria and were subsequently included in this scoping review. These 96 studies collectively provided insights into 167 patients who exhibited some form of oral and/or maxillofacial involvement. Notably, 25 % of these patients were within the age range of 0-6 months. It is worth highlighting that only 22 out of the 96 studies (22.9 %), had the primary objective of evaluating dental and/or maxillofacial deformities. Among the patients studied, a prevalent pattern emerged, revealing that severe anomalies such as micrognathia (56 %), high-arched palate (29 %), cleft palate (40 %), limited mouth opening (31 %), and dental anomalies (28 %) were frequently observed. Importantly, many of these patients were found to have more than one of these anomalies. Even though these maxillofacial impairments are known to be associated with dental problems (e.g., cleft palate is associated with oligodontia, hypodontia, and malocclusion), their secondary effects on the dental phenotype were not reported in the studies. CONCLUSION: Our findings have uncovered a notable deficiency in existing literature concerning dental and maxillofacial manifestations in AMC. This underscores the need for interdisciplinary collaboration and the undertaking of extensive prospective cohort studies focused on AMC. These studies should assess the oral and maxillofacial abnormalities that can impact daily functioning and overall quality of life.

The Human Phenotype Ontology in 2024: phenotypes around the world.

The Human Phenotype Ontology (HPO) is a widely used resource that comprehensively organizes and defines the phenotypic features of human disease, enabling computational inference and supporting genomic and phenotypic analyses through semantic similarity and machine learning algorithms. The HPO has widespread applications in clinical diagnostics and translational research, including genomic diagnostics, gene-disease discovery, and cohort analytics. In recent years, groups around the world have developed translations of the HPO from English to other languages, and the HPO browser has been internationalized, allowing users to view HPO term labels and in many cases synonyms and definitions in ten languages in addition to English. Since our last report, a total of 2239 new HPO terms and 49235 new HPO annotations were developed, many in collaboration with external groups in the fields of psychiatry, arthrogryposis, immunology and cardiology. The Medical Action Ontology (MAxO) is a new effort to model treatments and other measures taken for clinical management. Finally, the HPO consortium is contributing to efforts to integrate the HPO and the GA4GH Phenopacket Schema into electronic health records (EHRs) with the goal of more standardized and computable integration of rare disease data in EHRs.

A Portrait of the Rights of Children with Disabilities in Nigeria: A Policy Review.

Worldwide, 200 million children experience disability, with the vast majority living in low- and middle-income countries. The United Nations Convention on the Rights of the Child (CRC) places great importance on the rights of all children for the opportunities for survival, growth, health, and development. A subsequent document, the UN Convention on the Rights of Persons with Disabilities (CRPD), identifies children with disabilities as rights bearers who should be considered in all policies and programming worldwide. Nigeria, in 1991 and 2010, ratified the CRC and the CRPD, respectively. Nonetheless, knowledge of the extent to which their disability and child-directed policies considers these two key conventions, in ensuring that children and children with disabilities have access to care within their right remains limited. This study examined the extent to which Nigeria's current disability and childhood policies have integrated the two child and disability related conventions from the UN. Using a structured search of databases and Nigerian federal and state government websites, we conducted a policy review to identify their disability and child-related disability policies. We also included the CRC and CRPD reports submitted by the Nigerian government to the United Nations Office of the High Commissioner for Human Rights (OHCHR) (2008 and 2010 cyclical year). A thematic analysis, based on the CRC and CRPD report, identified the following six themes: participation, support systems, awareness raising, factors associated with adherence to the CRC, laws and rights, and services. The review showed that the available Nigerian disability policies were federal, with some state policies which aligned with the CRC and CRPD. Also identified was the lack of disability policies specific to children and their families. We concluded that, to ensure proper inclusion of the rights of all children, including those with disabilities, in Nigeria there is a need for a more optimal uptake of recommendations of the CRC and CRPD as laid out by the UN.

Perspectives from clinicians and managers: facilitators and barriers to the uptake of rehabilitation guidance for children with arthrogryposis.

PURPOSE: To identify the perceived facilitators and barriers among clinicians and managers about the uptake of expert guidance for rehabilitation of children with arthrogryposis multiplex congenita (AMC) in practice. METHODS: Qualitative study using individual interviews, guided by the Theoretical Domains Framework (TDF), to explore beliefs and to identify facilitators and barriers to guidance uptake. Interviews were conducted with a convenience sample of 15 clinicians working with children with AMC and four pediatric clinical managers using Microsoft Teams©. Interviews were then transcribed verbatim and analyzed by four independent reviewers using deductive and inductive coding. RESULTS: The TDF domains of Environmental Context and Resources, Behavioural Regulation, Reinforcement, Beliefs about Consequences, and Social Influences were shared amongst clinicians and clinical managers across North America and Europe as being relevant and influential on the target behaviour of using rehabilitation expert guidance to manage pediatric patients. Among clinicians only, the domain Memory, Attention, and Decision-Making Processes was also found relevant. Among managers only, the domain Social/Professional Role and Identity was found relevant. CONCLUSIONS: Coupling shared relevant domains amongst clinicians and managers with individual supports and barriers helps to map out what is needed to promote the uptake of rehabilitation guidance at multiple levels.

The uptake of expert guidance is helpful for rehabilitation professionals to align best practice with expert opinion based on clinicians and lived experience for a condition as rare as arthrogryposis multiplex congenita (AMC).In order to facilitate the uptake of guidance, rehabilitation professionals and clinical managers need to collaborate during the development and uptake in practice.Rehabilitation professionals require support for the uptake of guidance, such as training, regular team encounters, and a knowledge broker.Rehabilitation professionals and clinical managers should be aware of identified facilitators and barriers to the uptake of guidance, such as time, clinical resources, and accessibility.

Stakeholder engagement in the development of an upper extremity outcome measure for children with rare musculoskeletal conditions.

BACKGROUND: Upper extremity (UE) involvement is prevalent in 73% of individuals with arthrogryposis multiplex congenita (AMC), yet no AMC-specific outcome measure exists. When developing a measure specific to a population with a rare musculoskeletal condition, clinicians' and patients' perspectives and involvement is a crucial and necessary step. This study sought to determine the most clinically useful items for an outcome measure of UE function for children with AMC as defined by caregivers and clinicians. METHODS: To ensure the perspectives and needs of caregivers of children with AMC and clinicians were considered in the development of the UE measure for AMC, a Nominal Group technique (NGT) with caregivers of children with AMC (phase 1) followed by a three-round survey with clinicians (phase 2) were carried out. RESULTS: Phase 1: Eleven individuals participated in the nominal group technique and identified 32 items. The most important items were Picking up an object (n = 11), Eating (n = 10), Reaching mouth (n = 10), Getting out of bed (n = 10). Phase 2: Invitations to participate to an online survey was sent to 47 experts in the field of AMC, 20 participants completed round 1, 15 completed round 2 and 13 completed round 3. Throughout the survey, participants were asked about movement required to screen the UE, essential domains to be included in the measure, establishing a scoring guide and identifying tasks associated with joint motion and position. CONCLUSION: A preliminary version of an UE AMC-specific outcome measure was developed with the help of caregivers' perspectives and expert opinions.

Arthrogryposis multiplex congenita (AMC) is a rare musculoskeletal condition affects the joints and muscles of the body. In about 70% of the cases, it affects the upper extremities (UE). However, there is no specific outcome measure for UE function in children with AMC. An outcome measure refers to a tool or method used to assess and measure the results or effects of a particular treatment, intervention, or condition. It helps healthcare professionals and researchers understand the impact or outcome of a specific situation, such as the level of improvement or changes in a person's health or function. The goal of this study was to develop such a measure while accounting for the perspectives of youth with AMC, their caregivers and clinicians. To achieve this, a study was conducted in two phases. In the first phase, a Nominal Group technique (NGT) was used to gather input from caregivers of children with AMC. Eleven individuals participated and identified 32 items, with the most important being picking up an object, eating, reaching the mouth, and getting out of bed. In the second phase, a three-round survey was sent to 47 experts in the field of AMC, with 20 participants completing the first round, 15 completing the second round, and 13 completing the third round. The survey asked participants about screening UE movement, essential domains to include in the measure, establishing a scoring guide, and identifying tasks associated with joint motion and position. With the help of caregivers' perspectives and expert opinions, a preliminary version of an UE AMC-specific outcome measure was developed. This measure will be useful in assessing the UE function in children with AMC and will aid clinicians in developing appropriate treatment plans for this rare condition.

The Design, Development, and Usability Testing of an eHealth Program for Youths With Osteogenesis Imperfecta: Protocol for a 2-Phase User-Centered Mixed Methods Study.

BACKGROUND: Innovative approaches are needed to address the self-management needs of youths with osteogenesis imperfecta (OI) transitioning into adult-oriented health care systems. Using a sequentially phased research approach, the goal is to design, develop, and test the usability of an innovative eHealth program called "Teens Taking Charge: Managing OI Online," hereafter named "Teens OI." This program seeks to optimize self-management, facilitate a successful transition to adult care, and address a critical gap in the quality of care for youths with OI. OBJECTIVE: The study objectives are to (1) design and develop an English and French version of the Teens OI and (2) test the usability of the Teens OI in terms of efficiency, effectiveness, and satisfaction from the perspectives of youths with OI and their parents. METHODS: A user-centered design is presently in progress to design and develop Teens OI. A "Website Design and Development Council" (ie, Council) has been convened, with 20 youths and parent dyads recruited and global experts surveyed at an international meeting. With unanimous support from the Council, usability testing of the Teens OI will ensue in 4 iterative cycles with 32 youth-parent dyads. All sociodemographic and usability metrics will be descriptively analyzed. All recorded interview and focus group data are analyzed using content analysis techniques involving an iterative process of data reduction, data display, conclusion drawing, and verification. RESULTS: As of December 2022, an 8-person, interdisciplinary Teens OI council, comprising 4 health care professionals, 3 youths and young adults with OI, and 1 parent, has been convened to oversee the design and development of Teens OI. Two cycles of interviews have been conducted with 10 youths with OI with or without their parents (n=6) from December 2021 to September 2022. Data analysis has been in progress since April 2022. Aim 2 is ethically approved and will commence following the completion of content development, expected by late July 2023. Preliminary analysis indicates that the following topics need to be prioritized for the youths: mental health, pain, accessibility, medical care, education, community, and parental care. CONCLUSIONS: The proposed study will design and develop a self-management and transitional care program for youths with OI in partnership with patients, caregivers, and health care professionals. This study leverages youths' openness to adopt eHealth technologies to meet their needs and has the potential to actively engage them to autonomously manage their lifelong conditions, and facilitate a successful transition to adult health care. Finally, the proposed study will also address a critical gap in the quality of care and the growing concern that the OI population transitioning from pediatric to adult care is at risk of various adverse events associated with the transition.

Measurement Repeatability and Reproducibility of Virtual Goniometry of a Set of Acquired Images in Youths with Arthrogryposis Multiplex Congenita.

OBJECTIVES: To evaluate the intra-rater repeatability and the inter-rater reproducibility of using a virtual goniometer to measure upper and lower extremity joint range of motion (ROM) in youths with arthrogryposis multiplex congenita (AMC). METHODS: Youths presenting with AMC aged 8 to 21 years old were recruited. ROM of the upper and lower limbs were assessed remotely during a teleassessment on a video-conferencing platform. Screen captures were taken and ROM were measured by two raters, two-weeks apart, using a virtual goniometer. Intraclass correlation coefficient (ICC) and associated 95% confidence interval (CI) were calculated to assess intra-and inter-rater repeatability and reproducibility. RESULTS: Nine participants were included with a median age of 15.9 years (range: 11.3 to 20.8 years). The overall intra-rater ICC was 0.997 (95% CI:0.996 to 0.997) for the first rater and 0.993 (95% CI:0.992 to 0.994) for the second rater. The inter-rater ICC ranged from 0.410 (95% CI:-0.392; 0.753) for forearm pronation to 0.998 (95% CI:0.996; 0.999) for elbow flexion. CONCLUSIONS: Results of the current study suggest that virtual goniometry is reproducible and repeatable for the ROM of most joints. Future studies should evaluate procedural reliability and validity of the proposed method for youth with complex conditions.

Talectomy for arthrogrypotic foot deformities: A systematic review.

BACKGROUND: Arthrogryposis multiplex congenita (AMC) is one of the most common congenital joint contracture syndromes. Talectomy has been proposed for severe foot deformities in AMC, but the literature is limited. The purpose of this systematic review is to evaluate the indications, outcomes and complications of talectomy in arthrogrypotic foot deformities. METHODS: The articles were found through Embase and Medline. Screening was conducted by two independent investigators with disagreements resolved by a third reviewer. Relevant data regarding demographics, outcomes and complications were collected. RESULTS: Of 232 feet, 71.98 % and 62.22 % had clinical and radiographic improvements respectively. Amongst 122 patients, 92.62 % could ambulate following surgery. Recurrent deformities and revision surgery were seen in 16.81 % and 13.36 % of cases respectively. CONCLUSIONS: Talectomy is a valid surgical option for severe arthrogrypotic foot deformities with favorable post-operative outcomes and low complication rate.

Current rehabilitation practice for the evaluation and treatment of children with arthrogryposis: an international survey.

PURPOSE: To describe the current practices in rehabilitation for the evaluation and treatment of children with arthrogryposis multiplex congenita (AMC). MATERIALS AND METHODS: Rehabilitation practitioners worldwide with at least 2 years of experience with AMC were invited to complete an electronic survey on the evaluations and treatments used with children with AMC within five areas: muscle and joint function, self-care, mobility, pain, participation and psychosocial wellbeing. RESULTS: Sixty five participants from nine countries completed the survey. Participants completed the sections applicable to their practice. Number of participants within each area varied between 24 and 53. Over 80% of participants used non-standardized evaluations across areas while <50% used patient-reported or standardized measures. Stretching of upper and lower limbs was reported by >80% across ages and clinical presentation severity. Strengthening reported by >70% was mainly used among children >3 years old with less severe contractures. Other interventions used across areas included orthotics (>70%), positioning (>80%), activity-based training (>80%), assistive devices for self-care (>50%) and mobility (>80%), and energy conservation (>70%). Over 70% of participants were involved in perioperative rehabilitation. CONCLUSION: Knowledge of current pediatric rehabilitation practice in AMC, together with empirical evidence, may guide clinical decision-making and identify avenues for future research.

Arthrogryposis multiplex congenita (AMC) is a group of rare conditions and there is currently little empirical evidence on rehabilitation, therefore expert opinion is important to guide best practice.Rehabilitation practitioners should consider the areas of muscle and joint function, self-care and mobility, pain, participation, and psychosocial wellbeing when evaluating and developing a treatment plan for children with AMC.Considering the heterogeneity of AMC, different assessment tools may be selected depending on the clinical presentation of each child.In addition to stretching, orthotic use, and strengthening, the use of activity based training and assistive equipment is important to promote self-care, mobility and participation.

Epidemiology, aetiology, interventions and genomics in children with arthrogryposis multiplex congenita: protocol for a multisite registry.

INTRODUCTION: Arthrogryposis multiplex congenita (AMC) is an umbrella term including hundreds of conditions with the common clinical manifestation of multiple congenital contractures. AMC affects 1 in 3000 live births and is caused by lack of movement in utero. To understand the long-term needs of individuals diagnosed with a rare condition, it is essential to know the prevalence, aetiology and functional outcomes in a large sample. The development and implementation of a multicentre registry is critical to gather this data. This registry aims to improve health through genetic and outcomes research, and ultimately identify new therapeutic targets and diagnostics for treating children with AMC. METHODS AND ANALYSIS: Participants for the AMC registry will be recruited from seven orthopaedic hospitals in North America. Enrollment occurs in two phases; Part 1 focuses on epidemiology, aetiology and interventions. For this part, retrospective and cross-sectional data will be collected using a combination of patient-reported outcomes and clinical measures. Part 2 focuses on core subset of the study team, including a geneticist and bioinformatician, identifying causative genes and linking the phenotype to genotype via whole genome sequencing to identify genetic variants and correlating these findings with pedigree, photographs and clinical information. Descriptive analyses on the sample of 400 participants and logistic regression models to evaluate relationships between outcomes will be conducted. ETHICS AND DISSEMINATION: Ethical approval has been granted from corresponding governing bodies in North America. Dissemination of findings will occur via traditional platforms (conferences, manuscripts) for the scientific community. Other modalities will be employed to ensure that all stakeholders, including youth, families and patient support groups, may be provided with findings derived from the registry. Ensuring the findings are circulated to a maximum amount of interested parties will ensure that the registry can continue to serve as a platform for hypothesis-driven research and further advancement for AMC.

Quality of life in pediatric-onset multiple sclerosis: Different disease course, different impact, different measurement approach needed.

OBJECTIVE: To understand the impact of pediatric multiple sclerosis (MS), health-related quality of life (HRQL) measures have been used. However, specific areas of concern of youths with MS are not known. The objective of this study was to contribute content for inclusion in a new condition-specific measure of the life impact of MS for children and adolescents. METHODS: A patient engagement framework was used, and an online survey was developed using the Patient Generated Index (PGI). Text threads generated by the PGI were mapped to the International Classification of Functioning, Disability, and Health (ICF) and the Comprehensive ICF Core Set for MS. RESULTS: A total of 20 people completed the PGI survey of which 11 were youths with MS aged 14 to 22 years. Over 75% of the areas nominated by youths with MS were related to activities and participation and approximately 20% were related to body function. In contrast, 60% of the areas nominated by parents were related to body function. This finding indicated that a measure of life impact would need to include both impairments associated with MS and important activities and roles. This new approach has a disability component covers MS-related impairments and is completed using the PGI system where the youth select disability areas affected by MS, rate, and prioritize each area for improvement. The "quality of life" component queries those areas that are going well. CONCLUSION: This new measurement approach could prove useful in overcoming challenges in developing condition-specific measures for rare conditions.

Expert guidance for the rehabilitation of children with arthrogryposis: protocol using an integrated knowledge translation approach.

BACKGROUND: Arthrogryposis multiplex congenita (AMC) is a group of rare congenital disorders characterized by multiple joint contractures present at birth. Contractures can affect different body areas and impact activities of daily living, mobility and participation. Although early rehabilitation is crucial to promote autonomy and participation in children with AMC, empirical evidence to inform best practice is scarce and clinical expertise hard to develop due to the rarity of AMC. Preliminary research involving stakeholders in AMC (youth with AMC, parents, and clinicians) identified priorities in pediatric rehabilitation. Scoping reviews on these priorities showed a lack of high quality evidence related to rehabilitation in AMC. The objective of this project is to provide rehabilitation expert guidance on the assessment and treatment of children with AMC in the areas of muscle and joint function, pain, mobility and self-care, participation and psychosocial wellbeing. METHODS: An integrated knowledge translation approach will be used throughout the project. Current rehabilitation practices in AMC will be identified using a clinician survey. Using the Grading of Recommendations, Assessment, Development and Evaluations framework (GRADE) approach, a panel of interdisciplinary expert clinicians, patient and family representatives, and researchers will develop expert guidance on the assessment and treatment for pediatric AMC rehabilitation based on findings from the scoping reviews and survey results. Consensus on the guidance statements will be sought using a modified Delphi process with a wider panel of international AMC experts, and statements appraised using the Appraisal of Guidelines for Research and Evaluation II (AGREE II) tool. Theoretical facilitators and barriers toward implementing clinical guidance into practice will be identified among rehabilitation clinicians and managers to inform the design of dissemination and implementation strategies. DISCUSSION: This multi-phase project will provide healthcare users and providers with research-based, expert guidance for the rehabilitation of children with AMC and will contribute to family-centered practice.

Arthrogryposis multiplex congenita (AMC) is a group of rare disorders where a child is born with stiff joints. Joint stiffness can be present in different parts of the body, making it difficult for the child to move, to walk and to participate in activities. Rehabilitation interventions starting early in life are very important to maximize autonomy. AMC being rare, it is difficult for clinicians to develop experience with this population and there is little research specific to rehabilitation interventions in AMC. In a previous research project, a group of youth with AMC and their families identified five areas of priority for rehabilitation: muscle and joint function, pain, mobility and self-care, participation and psychosocial wellbeing. The purpose of this project is to provide guidance for the evaluation and treatment of children with AMC, in these priority areas. The project involves multiple steps. First, we will perform an online survey with international rehabilitation practitioners to learn about current evaluation and treatment approaches used with children with AMC. We will then bring together expert clinicians, patient and family representatives, and researchers to develop the guidance statements. Then, we will perform an online survey with a larger group of international experts to validate and finalize the guidance statements. Finally, we will interview rehabilitation clinicians and managers to find out about what could help them or limit them in integrating this guidance into their practice. This project will provide healthcare users and providers with research and expert-based guidance for the rehabilitation of children with AMC.

Psychosocial wellbeing among children and adults with arthrogryposis: a scoping review.

BACKGROUND: Arthrogryposis multiplex congenita (AMC) is a group of congenital conditions characterized by joint contractures in two or more body areas. Management of AMC starts early in life and focuses on improving mobility and function through intensive rehabilitation and surgical interventions. Psychosocial wellbeing is an important determinant of health and the psychosocial experience of individuals with AMC should be considered in the management of this condition. The aim of this scoping review was to explore what is known about the psychosocial wellbeing of children and adults with AMC, to identify the outcome measures used and to explore the factors associated with psychosocial outcomes in this population. METHODS: A comprehensive search in four databases was conducted. Articles discussing psychosocial outcomes and outcome measures used with children or adults with AMC were included. Data on the measures used, psychosocial outcomes, and factors associated with psychosocial outcomes, were extracted and analyzed descriptively and synthesized narratively. RESULTS: Seventeen articles were included in this scoping review, ten including the pediatric population, six including adults and one article including both children and adults with AMC. The most commonly used outcome measures were the PODCI in the pediatric studies, and the SF-36 in studies on adults. In the pediatric studies, psychosocial outcomes were often secondary, compared to the studies on adults. Results showed that in both children and adults, psychosocial outcomes are comparable with the levels of the general population. Qualitative studies reflected the affective needs of this population and issues with emotional wellbeing. Factors such as fatigue and pain were associated with poorer psychosocial outcomes in adults with an impact on social relationships, intimacy and family planning. CONCLUSION: Validated outcome measures, qualitative approaches and longitudinal studies are needed to better understand the psychosocial outcomes in AMC over time. Psychosocial support should be part of the multidisciplinary management of AMC throughout the lifespan.
