Comorbidities in cerebral palsy: a patient registry study

Characteristics of children with ataxic cerebral palsy

BACKGROUND

To compare the characteristics, functional levels, and comorbidities of children with ataxic cerebral palsy (CP), with those of children with other CP subtypes.

METHODS

A cross-sectional study of children with CP born between 2000 and 2019 as reported in the Scandinavian national CP follow-up programmes and quality registries. Data for age, sex, levels of the Gross Motor Function Classification System (GMFCS), the Manual Ability Classification System (MACS), the Communication Function Classification System (CFCS), epilepsy, intellectual disability, and pain were extracted.

RESULTS

There were 302 children (3.9%) with ataxic CP and 7336 children (96.1%) with other subtypes. Children with ataxic CP differed significantly from other subtypes, with a greater proportion classified in GMFCS II (37.7% vs. 15%), MACS II (41.4% vs. 24.8%), and CFCS II (24.7% vs. 10.5%), more girls (50.7% vs. 41.7%), school-aged (47% vs. 41.6%), adolescents (33.4% vs. 25.4%), or had an intellectual disability (51.2% vs. 38.4%), but the prevalence of pain and epilepsy was similar between the subtypes.

CONCLUSIONS

Children with ataxic CP have different characteristics and functional levels than children with other subtypes. We recommend a thorough examination of motor performance, communication, and intellectual disability to meet the individual needs of children with ataxic CP.

Lower limb orthopedic surgery in children and adolescents with cerebral palsy is well captured using individualized Goal Attainment Scale (GAS) and Canadian Occupational Performance Measure (COPM) goals

PURPOSE

To investigate individualized goals set and goal attainment following lower limb orthopedic surgery for children and adolescents with cerebral palsy (CP).

MATERIALS AND METHOD

Retrospective chart review. Individualized goals set prior to orthopedic surgery using the Canadian Occupational Performance Measure (COPM) and/or Goal Attainment Scaling (GAS) with follow-up within 18 months post-surgery were analyzed. Goals were categorized into functional mobility, leisure, self-care and productivity.

RESULTS

44 children met the inclusion criteria, mean age 12.5 years (range 4.8-18.2yrs, SD 3.9), GMFCS I = 6, II = 19, III = 6, IV = 9, V = 4. In total 111 goals were analyzed, n = 79 COPM goals and n = 32 GAS goals. Clinically and statistically positive change was demonstrated in the COPM post-surgery, with mean changes of 3.74 (<0.0001) for performance and 4.26 (p < 0.0001) for satisfaction with performance. Of the 32 GAS goals set, 22 had an expected to much greater than expected outcome.

CONCLUSIONS

COPM goals demonstrated clinically and statistically significant improvement in performance and satisfaction with performance for children of all GMFCS levels post-surgery. GAS goals were not universally met. This study highlights the importance of individualized goal setting and recommends further evaluation into non-achievement of goals and the relationship between goal outcomes and surgery type.

Development of ankle and knee range of motion after isolated gastrocsoleus lengthening in children with cerebral palsy: a register-based longitudinal cohort study

BACKGROUND AND PURPOSE

 Outcome after gastrocsoleus lengthening in cerebral palsy (CP) is reported to be influenced by type of lengthening, age, CP subtype, and preoperative range of motion (ROM). We examined the development of ankle and knee ROM after 3 types of isolated gastrocsoleus lengthening.

METHODS

 This is a register-based longitudinal cohort study based on data from the Swedish Cerebral Palsy follow Up Program, of children born 2000-2011 who underwent isolated gastrocsoleus lengthening. ROM development was analyzed using mixed-effects modeling. Event limits were defined as ankle ROM ≤ 0° or ≥ 20° and knee extension deficit ≤ -10° and described in Kaplan-Meier curves and Cox regression analyses. The study protocol was published at clinicaltrials.gov.

RESULTS

 184 children were included. The mean differences in ankle ROM 10 years postoperatively between open tendo Achilles lengthening (OTAL) and percutaneous tendo Achilles lengthening (PTAL) was -2.3° (95% confidence interval [CI] -7.4 to 2.7), and between gastrocnemius lengthening (GCL) and PTAL -4.4° (CI -10.4 to 1.5). The adjusted hazard ratio (aHR), adjusted for baseline ROM, Gross Motor Function Classification System level, and CP subtype, comparing ankle event rates between OTAL and PTAL was 2.5 (CI 1.1-5.7). GCL was also associated with a higher event rate compared with PTAL, aHR 2.0 (CI 0.85-4.6). The adjusted mean difference in knee ROM at 10 years between OTAL and PTAL was 5.1° (CI 0.4-9.8), and between GCL and PTAL 1.9° (CI -3.6 to 7.6). Comparing event rates for the knee yielded uncertain results.

CONCLUSION

 PTAL appears at least as effective as OTAL and GCL for favorable ankle and knee ROM development in children with CP.

A pre-operative gastrointestinal optimization protocol to improve outcomes after intrathecal baclofen pump surgery

PURPOSE

Pediatric cerebral palsy patients carry frequent medical comorbidities and disproportionately consume hospital resources after neurosurgical procedures. We implemented an institutional pre-operative gastrointestinal (GI) optimization protocol to improve outcomes and decrease resource utilization.

METHODS

All 323 intrathecal baclofen surgeries from 2000 to 2023 were categorized relative to protocol implementation on July 1, 2017. Outcomes and resource utilization were compared.

RESULTS

The protocol change resulted in significantly fewer hospital readmissions (p = 0.001) for constipation, eliminating them and GI-related emergency visits. There was a reduction of 27 hospital days for constipation-related readmission (median 1 day per patient, IQR 1, 2 days). No differences were reported between the experimental groups including demographics or GI comorbidities. Post-operative complications within 30 days were comparable between groups regarding urinary tract infections, surgical-site infections, and spinal fluid leak. There were no differences in post-operative length of stay between groups.

CONCLUSION

A GI optimization protocol can eliminate a frequent source of hospital readmissions and GI-related emergency department visits after baclofen pump surgery, even accounting for baseline GI comorbidities. Preventing readmissions and emergency visits translates to lower hospital resource utilization and improves quality of care. Future efforts are warranted to improve outcomes and care efficiency for our most complex and resource-intensive patients.

Genetic Alterations in Atypical Cerebral Palsy Identified Through Chromosomal Microarray and Exome Sequencing

This study investigated the genetic causes of atypical cerebral palsy (CP) through chromosomal microarray (CMA) and exome sequencing (ES) in a cohort of 10 Korean patients to identify variants and expand the spectrum of mutations associated with atypical cerebral palsy. Whole ES and/or genome sequencing (GS) after routine karyotyping and CMA was performed to identify causative variants and expand the spectrum of mutations associated with atypical CP. In cases of atypical CP, scoliosis and/or kyphosis, ranging from mild to severe, were present in all patients. Epilepsy was a comorbidity in seven patients (70%), and intellectual disability (ID) was observed in varying degrees. This study identified three copy number variations (CNVs), including 15q11.2 microdeletion (n = 1), 17p11.2 duplication (n = 1), and 12p13.33p11.23 duplication/18p11.32 microdeletion (n = 1), and six likely pathogenic variants (LPVs) or pathogenic variants (PVs) detected in the SLC2A1, PLAA, CDC42BPB, CACNA1D, ALG12, and SACS genes (n = 6). These findings emphasize the significance of incorporating genetic testing into the diagnostic process for atypical CP to improve our understanding of its molecular basis and inform personalized treatment strategies. To further advance this research, future studies should focus on exploring genotype-phenotype correlations, assessing the functional impact of identified variants, and increasing the sample size to validate the observed patterns.

Developing a Profile of Canadian Children With Cerebral Palsy Who Require Augmentative and Alternative Communication

PURPOSE

Cerebral palsy (CP) is the most prevalent motor disability affecting children. Many children with CP have significant speech difficulties and require augmentative and alternative communication (AAC) to participate in communication. Despite demonstrable benefits, the use of AAC systems among children with CP remains constrained, although research in Canada is lacking.

METHOD

Data were collected as part of an exploratory survey of Canadian caregivers and clinicians (N = 60) who shared their perspectives on children's need for, access to, and use of AAC systems. Quantitative data were summarized using descriptive statistics. Qualitative data were analyzed using inductive content analysis.

RESULTS

Caregivers and clinicians reported high rates of need for AAC systems (> 75%) among children with CP. Both groups reported that access was roughly equivalent to need, although caregiver reports were lower. Despite high rates of need and access, only 38% of children used AAC systems. Children who used AAC primarily used high-tech systems, mostly to make choices, rather than engaging in meaningful reciprocal interactions and conversations.

CONCLUSIONS

Canadian children with CP who required AAC systems generally received them. However, AAC systems were not used to their full potential, suggesting limited participation in social and learning situations. Like reports on other pediatric populations, barriers to obtaining AAC systems related to service, family, and child-specific factors. Although our sample captured the complexity present in the CP population, sample sizes were small and unlikely to be representative of the population of Canada, indicating the need for further research on a national scale.

Priority setting for multicenter research among adults with cerebral palsy: a qualitative study

PURPOSE

Identify priorities for adult cerebral palsy (CP) research by engaging individuals with lived experience, clinical investigators, and community leaders.

MATERIALS AND METHODS

Qualitative descriptive study using iterative focus groups, followed by inductive thematic analysis. Participants included adults with CP and caregivers, clinical investigators, and community leaders in the CP and disability spaces. We explored research priorities among three research areas identified a priori- bone health, kidney health, and preventive care.

RESULTS

We conducted four focus groups (20 participants with lived experience; 10 clinical investigators; 9 community leaders). Most participants felt all topic areas were very important, though preventive care emerged as the top priority. We identified three overarching themes that cut across the various research areas discussed: patient and provider knowledge gaps; a precision medicine approach for adult CP care; and the need to address ableism.

CONCLUSIONS

Adults with CP face unique healthcare needs and risks as they age, and the evidence base to guide their care lags significantly behind. Our study identified preventive care as the top research priority for the adult CP research agenda. Next steps in this line of research should focus on interventions to facilitate primary and preventive care interactions for adults with CP.

Indications for tracheostomy placement in pediatric patients with cerebral palsy

BACKGROUND

Cerebral palsy (CP) is the most common neuromuscular disorder in children, and children with CP are at increased risk of respiratory distress potentially requiring tracheostomy placement. Previous studies have characterized indications for tracheostomy in neurologically compromised children, however no studies focus specifically on children with CP. The purpose of this study was to identify the indications for tracheostomy placement, sites of airway obstruction, and rate of decannulation in children with CP.

METHODS

We conducted a single-center retrospective chart review of all patients who presented with cerebral palsy and required tracheostomy at our center between 2005 and 2023. Patients were categorized according to primary indication for tracheostomy placement. The most common sites of airway obstruction in the cohort were recorded. The date of decannulation was recorded for those patients who had undergone decannulation.

RESULTS

933 patients with tracheostomies were identified, of whom 169 (18 %) had CP and 122 met inclusion criteria. The median age at tracheostomy placement was 1.69 (IQR 0.539-6.609) years. The most common indications for tracheostomy placement were: prolonged intubation or BiPAP dependence (81 %), airway obstruction/hypotonia (13 %), and aspiration/recurrent respiratory infection (6 %). At the time of tracheostomy placement: 38 % of patients had a single site of upper airway obstruction, while 27 % had multi-level obstruction. The most common sites of upper airway obstruction were the supraglottis (23.0 %), tongue base (12 %), and the tonsils/pharyngeal wall (8 %). 24 % of patients had tracheobronchomalacia, and 16 % had subglottic stenosis. Among all patients, 4 of 122 (3 %) were ultimately decannulated.

CONCLUSIONS

Patients in our cohort most often received tracheostomy after failure of less invasive ventilation therapies. Tracheostomy placement occurred at a young age. Patients presented with a variety of sites of airway obstruction. Decannulation rate in this cohort was low. Further work is needed to confirm indications for tracheostomy placement and decannulation rate in this population.

Cerebral palsy and perinatal mortality in children born in Norway to immigrant mothers

AIM

To compare the prevalence and clinical characteristics of cerebral palsy (CP), and perinatal mortality, in children born to non-immigrant mothers with children born to immigrant mothers.

METHOD

This was a registry-based cross-sectional study. Data on children born from 2000 to 2016 were extracted from the Medical Birth Registry of Norway and linked to the Norwegian Quality and Surveillance Registry for Cerebral Palsy. The mother's country of birth was categorized into three groups: non-immigrant (born in Norway); immigrant from high-income countries (HICs); and immigrant from low- and middle-income countries (LMICs) (born abroad giving birth in Norway). Birth prevalence of CP and prevalence of perinatal mortality per 1000 live births were calculated. Odds ratios (ORs) for CP among live-born children of non-immigrant mothers compared to mothers from HICs and LMICs were calculated using logistic regression, both unadjusted and adjusted for each risk factor for CP. Pearson χ2 tests were used to compare the proportions of clinical characteristics.

RESULTS

The prevalence of CP among non-immigrant mothers was 2.11 per 1000 live births, 1.44 among mothers from HICs, and 1.71 among mothers from LMICs. The OR for CP in mothers from HICs was 0.68 and 0.81 in mothers from LMICs. Despite mothers from LMICs having higher proportions of consanguinity and lower folate intake, and their children having lower Apgar scores, the ORs for CP were unchanged after adjusting for these. Yet, children born to mothers from LMICs had higher perinatal mortality; their children with CP had higher proportions of intellectual disability.

INTERPRETATION

The lower birth prevalence of CP among children born to mothers from LMICs was unexpected. Yet, children born to mothers from LMICs had higher perinatal mortality, which could impact the number of live-born children with CP.

Executive function is associated with behaviour problems in children and adolescents with cerebral palsy and intellectual disability

BACKGROUND

Children and adolescents with cerebral palsy (CP) commonly have behaviour problems. The present study aimed to determine which of the most common clinical features experienced by children and adolescents with CP and intellectual disability are associated with behaviour problems.

METHOD

We investigated 11 possible associated variables including epilepsy, visual and hearing impairments, motor difficulties, communication and speech difficulties, pain, sleep disturbance, executive function (EF) deficits, type of CP, and parent stress. Thirty-eight parents or guardians of children aged 6 to 17 years with CP and intellectual disability (parent informed) completed proxy and self-report standardised questionnaires.

RESULTS

EF deficits and parent stress were significantly associated with behavioural problems.

CONCLUSION

For children and adolescents with CP and intellectual disability, the present study suggests close attention should be placed on specific clinical features including EF deficits and parent stress when considering variables associated with behaviour problems.

Utilization of special services among children and youth with special healthcare needs: A time-to-event analysis of the national survey of children's health data, 2016-2022

BACKGROUND

Special services including physical, occupational, speech, or behavioral therapies are associated with enhanced long-term functioning and well-being of children and youth with special healthcare needs (CYSHCN). Yet, there is a lack of recent evidence on the utilization of these services, and the age at which CYSHCN first receive them.

OBJECTIVE

This study assessed the distribution, timing, and determinants of special services utilization across different types of special healthcare needs.

METHODS

Data from 63,734 caregivers of CYSHCN aged 0-17 years from the 2016-2022 National Survey of Children's Health were analyzed using Rao-Scott Chi-Square, Log-rank, and Cox proportional hazard tests.

RESULTS

Overall, 41.9 % of CYSHCN ever received special services, including 91.4 %, 90.3 %, 88.0, and 34.1 % of children and youth with Down syndrome, cerebral palsy, autism, and other special healthcare needs (OSHCN), respectively. Children with Down syndrome and cerebral palsy received special services earlier than those with autism or OSHCN. Utilization of special services was higher among male children and youth (aHR 1.41; 95 % CI: 1.33-1.49), aged 0-5 years (aHR: 4.70; 95 % CI: 4.32-5.11), second or later born children (aHR: 1.18; 95 % CI: 1.10-1.26), from families with low-income (aHR: 1.14; 95 % CI: 1.04-1.24), living with married parents (aHR: 1.11; 95 % CI: 1.04-1.19), consistently insured (aHR: 1.24; 95 % CI: 1.08-1.42), and with a more complex health condition (aHR: 3.40; 95 % CI: 3.13-3.70) compared to their counterparts.

CONCLUSIONS

These findings highlight the necessity of adopting tailored approaches for children with different special healthcare needs to optimize and sustain the utilization of special services.

The relationship between pneumonia and dental visits in patients with cerebral palsy: A nationwide registry-based cohort study in Taiwan

Background/purpose

In general, improving oral health can reduce the risk of pneumonia. The purpose of this retrospective cohort study was to investigate the risk of pneumonia between cerebral palsy (CP) cohort and non-CP cohort as well as the association of pneumonia with the number of dental visits in CP patients in Taiwan.

Materials and methods

We identified 10,544 patients who were diagnosed with CP between 2010 and 2019 from the Taiwan National Health Insurance Research Database. 63,264 individuals who had never been diagnosed with CP were captured and matched in a 6:1 ratio. Cox proportional hazard regression analysis was adopted to assess the hazard ratio (HR) of pneumonia between CP cohort and non-CP cohort.

Results

Our findings demonstrated that CP cohort had 2.619-fold risk for pneumonia as compared with non-CP cohort after adjustment (95 % CI = 2.574-2.813, P < 0.0001). Cox regression analysis indicated that the CP group had significantly higher incidence risk of pneumonia (log rank P < 0.0001). Higher risks of pneumonia in CP patients were associated with younger age, and lower urbanization level. Some comorbidities as well as history of pneumonia had the higher aHR for pneumonia within 180 days prior to index date. In addition, there was a positive association with the more than two dental visits for the decrease 0.887-fold incidence of pneumonia in CP-cohort as compared with no dental visit (95 % CI: 0.799-0.984).

Conclusion

Taken together, CP patients had a higher risk of pneumonia. Dental visits are beneficial for preventing the risk of pneumonia in CP patients. The patients with CP should receive regular dental checkup.

The Case for Parent-Implemented Programs to Mitigate Musculoskeletal Complications in Children With Severe Cerebral Palsy in Resource-Limited Settings

Children with severe cerebral palsy are vulnerable to orthopedic complications, particularly in resource-limited settings, which can compound disability. A focus on home-based programs may help to improve their quality of life and participation.

Impact of care coordination on service utilisation for children with medically complex cerebral palsy

AIM

Complex care programmes for children with medically complex cerebral palsy (CP) exist; however, evidence for their impact is limited. This study (i) explored the impact of The Royal Children's Hospital Complex Care Hub (CCH) on hospital service utilisation rates over a 3-year period for children with medically complex CP compared with those eligible but received routine care, and (ii) compared health, disability and socio-demographic characteristics of children and their families in both groups.

METHODS

Electronic medical record data from 78 children (mean age 9.43 years, females n = 37) with medically complex CP who accessed CCH services, and 92 (mean age 10.86 years, females, n = 39) who received routine care were included. Multivariable regression was used to analyse service utilisation: number of emergency department (ED) presentations, length/number of inpatient and intensive care unit admissions and number/type of hospital appointments. Critical health-care needs, functioning/disability profile and child/family demographics for each group were compared.

RESULTS

More children in the CCH group had a mixed motor type (73.1% vs. 15.2%), were classified within Gross Motor Function Classification System level V (76.9% vs. 34.8%), had respiratory, nutrition and social support needs and epilepsy. Children receiving CCH services had higher service utilisation rates; ED presentations (rate ratio (RR) = 1.81, 95% confidence interval (CI): 1.09-3.01), inpatient admissions (RR = 2.77, 95% CI: 2.01-3.83), outpatient encounters (RR = 1.69, 95% CI: 1.31-2.18) and telephone encounters (RR = 6.05, 95% CI: 4.56-8.02).

CONCLUSIONS

Children with medically complex CP accessing a complex care service have higher service utilisation rates yet have more complex clinical presentations and higher support needs.

Unravelling age-related gait decline in cerebral palsy: insights into physiological changes and functional implications through an observational study-a French study protocol in a laboratory setting

INTRODUCTION

Cerebral palsy (CP) presents a complex neurodevelopmental disorder with a spectrum of motor impairments stemming from early brain injury. Whereas CP is traditionally viewed as a non-progressive condition, emerging evidence suggests a progressive decline in mobility and function, particularly in adulthood. Despite the prevalence of self-reported age-related gait decline in adults with CP, objective evidence supporting this phenomenon remains limited. Moreover, mechanistic insights into these functional alterations and their comparison with typically developing (TD) peers are lacking. To address this gap, our study aims to objectively assess age-related changes in gait performance among individuals with CP while examining physiological differences compared with TD peers.

METHODS AND ANALYSIS

This protocol will compare the mobility of individuals with and without CP within two age groups (18-25 and 35-50 years old). Participants at Gross Motor Function Classification System levels I-II at age 18 will be invited to partake in the study. Every participant will be invited to complete four visits investigating a wide range of mobility related measures: walking performance, muscle strength, cardiopulmonary performance, fatigability, cost of walking and quantitative gait analysis. Through this comprehensive analysis encompassing gait performance metrics, self-reported outcomes, muscle strength, biomechanics and metabolical cost of walking, and fatigability, we seek to elucidate the underlying mechanisms driving age-related gait decline in adults with CP and inform targeted interventions to maintain function and quality of life.

ETHICS AND DISSEMINATION

The study has been approved by the French ethics board (#2022-A02510-43) and will be communicated through conferences, articles and to participants through layman terms.

Functioning profile and related impairments of children and adolescents with cerebral palsy - PartiCipa Brazil preliminary results

BACKGROUND

Limited information is available about functioning and related impairments of children and adolescents with Cerebral Palsy (CP) in low- and middle-income countries (LMIC) like Brazil. The aim of this study is to describe the characteristics, functioning, and impairments of Brazilian children and adolescents with CP.

METHODS

Cross-sectional preliminary study as part of the PartiCipa Brazil multicentered cohort study. Families of children and adolescents with CP from Brazil, 4 months to 15 years, were enrolled. They responded to an online survey with questions about their child's health condition, impairments, contextual factors, and functioning according to the Gross Motor Function Classification System (GMFCS) and the Manual Ability Classification System (MACS). Data were described as frequencies, percentages, means, and standard deviations, according to age bands.

RESULTS

Of the 404 participants (6.5±3.6 years) enrolled in this preliminary analysis, 54.7% are male, 90.4% under 12 years of age, 77.7% have bilateral CP, 49% in GMFCS levels IV and V, and 50.7% in MACS levels II and V. Most participants are from Southeast (63.4%) and Centre-west (19.5%) of Brazil. Regarding the impairments and functioning limitations: 1 in 2 did not talk; 1 in 2 has epilepsy; 2 of 5 reports pain, 1 of 4 has visual impairments, 3 out of 5 did not feed themselves, 1 out of 20 has a hearing impairment and 1 of 4 did not go to school.

CONCLUSION

This first preliminar Brazilian study shows a high prevalence of children at MACS levels II and V and GMFCS levels IV and V, representing almost half of the group, indicating more impairments and limitations than children/adolescents from high-income countries. This study provides a preliminary deeper understanding of the key impairments and limitations in activities among children and adolescents with CP from various Brazilian regions.

Exploring the quantity and quality of symptoms of attention deficit hyperactivity disorder and intelligence in children with cerebral palsy: a case-control study

To evaluate whether attention deficit hyperactivity disorder (ADHD) symptoms differ across cerebral palsy (CP) and the relationship of these symptoms to CP disease data. Each of the three groups (CP, ADHD, and control) included 22 volunteers, aged 6-18. The CP group was divided into two groups, with and without ADHD (CP + ADHD and CP-ADHD). The groups were compared in terms of clinical data, ADHD symptoms, and intelligence levels. ADHD was reported in 36.4% of the CP group and 9.1% of the control group (p = 0.031). The rate of moderate/severe motor disability was higher (p = 0.052), and the Wechsler Intelligence Scale for Children-Revised (WISC-R) (total, performance, verbal) scores were lower in the CP + ADHD group compared to the CP-ADHD group (p = 0.005, p = 0.005, p = 0.002). Cognitive problems/inattention scores were higher in the CP group compared to the control group (p = 0.015). WISC-R (total, performance, verbal) scores were lower in the CP group compared to the ADHD group (p = 0.008, p = 0.001, p = 0.047) and the control group (p < 0.001, p < 0.001, p = 0.001).

CONCLUSION

ADHD is more common in CP and may be seen in a predominantly inattentive presentation. It is related to a worse motor disability and intelligence level in CP.

WHAT IS KNOWN

• Compared to the general population, ADHD is reported to be more common in children with CP.

WHAT IS NEW

• ADHD may be seen in a predominantly inattentive presentation rather than the other presentations in children with CP. • ADHD is related to a worse motor disability and intelligence level in CP.

Associated impairments among children with cerebral palsy: findings from a cross-sectional hospital-based study in Vietnam

OBJECTIVE

This study aims to explore the associated impairments of cerebral palsy (CP) and their correlates among children with CP in Vietnam.

DESIGN

Descriptive cross-sectional study using hospital-based surveillance.

SETTING

National Children's Hospital, Hanoi, Vietnam between June and November 2017.

PARTICIPANTS

765 children with CP were recruited.

OUTCOME MEASURES

We assessed clinical characteristics of CP, associated impairments (epilepsy, intellectual, visual, hearing, speech impairments) and their correlates. We performed descriptive analyses (median, IQR and proportion). χ2 test and Fisher's exact test were used for categorical variables. Univariate logistic regression and multivariate logistic regression models were established and associated impairments were included as independent variables.

RESULTS

The median age of children was 1.7 years (IQR=2.7). Quadriplegia was the predominant subtype (69.5%) and 46.5% were at Gross Motor Function Classification System level IV-V. Of children, 76.3% had ≥one associated impairment, most commonly speech or intellectual impairments (59.1% and 57.8%, respectively). Severity of motor impairment, type of CP, maternal and perinatal factors (eg, gestational age, perinatal asphyxia, timing of injury causing CP) were associated with greater risk of associated impairments.

CONCLUSION

Children with CP have a high burden of associated impairments. Findings from our study will inform the development and implementation of appropriate screening and interventions and reduce the long-term adverse effects of these impairments on individuals with CP and their socioeconomic impact.

Comparison of two modeling approaches for the identification of predictors of complications in children with cerebral palsy following spine surgery

BACKGROUND

Children with non-ambulatory cerebral palsy (CP) frequently develop progressive neuromuscular scoliosis and require surgical intervention. Due to their comorbidities, they are at high risk for developing peri- and post-operative complications. The objectives of this study were to compare stepwise and LASSO variable selection techniques for consistency in identifying predictors when modelling these post-operative complications and to identify potential predictors of respiratory complications and infections following spine surgery among children with CP.

METHODS

In this retrospective cohort study, a large administrative claims database was queried to identify children who met the following criteria: 1) ≤ 25 years old, 2) diagnosis of CP, 3) underwent surgery during the study period, 4) had ≥ 12-months pre-operative, and 5) ≥ 3-months post-operative continuous health plan enrollment. Outcome measures included the development of a post-operative respiratory complication (e.g., pneumonia, aspiration pneumonia, atelectasis, pleural effusion, pneumothorax, pulmonary edema) or an infection (e.g., surgical site infection, urinary tract infection, meningitis, peritonitis, sepsis, or septicemia) within 3 months of surgery. Codes were used to identify CP, surgical procedures, medical comorbidities and the development of post-operative respiratory complications and infections. Two approaches to variable selection, stepwise and LASSO, were compared to determine which potential predictors of respiratory complications and infection development would be identified using each approach.

RESULTS

The sample included 220 children. During the 3-month follow-up, 21.8% (n = 48) developed a respiratory complication and 12.7% (n = 28) developed an infection. The prevalence of 11 variables including age, sex and 9 comorbidities were initially considered to be potential predictors based on the intended outcome of interest. Model discrimination utilizing LASSO for variable selection was slightly improved over the stepwise regression approach. LASSO resulted in retention of additional comorbidities that may have meaningful associations to consider for future studies, including gastrointestinal issues, bladder dysfunction, epilepsy, anemia and coagulation deficiency.

CONCLUSIONS

Potential predictors of the development of post-operative complications were identified in this study and while identified predictors were similar using stepwise and LASSO regression approaches, model discrimination was slightly improved with LASSO. Findings will be used to inform future research processes determining which variables to consider for developing risk prediction models.

Tools used to measure the impact of comorbidities on surgical outcomes in children with complex chronic conditions: A scoping review

AIM

To identify and describe assessment tools used to measure the impact of comorbidities on postoperative outcomes in children with complex chronic conditions (CCC).

METHOD

This was a scoping review using five electronic databases. The search was conducted in March 2022 by a medical librarian. There were no date or language restrictions. Included studies were full-text articles published in peer-reviewed journals that described a tool used to measure the impact of comorbidities in children with CCC to assess postoperative outcomes. A standardized data charting tool was used.

RESULTS

A total of 2157 articles were retrieved. Five studies reporting on six comorbidity measures met inclusion criteria. All were cohort studies and were secondary analyses of data from an administrative database (n = 4) or a patient registry (n = 1). Sample sizes ranged from 645 to 25 747 participants. One paper described the assessment of reliability. Only one form of validity - predictive validity - was assessed in three papers for five measures.

INTERPRETATION

Findings from this scoping review revealed a paucity of comorbidity assessment tools validated for use with children with CCC; significant conceptual and measurement challenges exist in the current scientific literature.

WHAT THIS PAPER ADDS

Five studies used formal risk assessment approaches to evaluate postoperative outcomes in children with complex chronic conditions. Conceptual and methodological differences between comorbidity indexes and risk prediction models are explicated. Further development of prediction science is needed for determining postoperative outcomes. Enhanced preoperative comorbidity assessment will identify children at risk of poor outcomes.

Motor function and gait decline in individuals with cerebral palsy during adulthood: a narrative review of potential physiological determinants

Cerebral palsy (CP) is the most common childhood-onset disability. The evolution of gait according to severity is well known amongst children and thought to peak between 8 and 12 years of age among those walking without assistive devices. However, among adults, clinical experience as well as scientific studies report, through clinical assessments, questionnaires and interviews, increasing walking difficulties leading to an increased dependency of assistive devices in everyday ambulation. For many individuals with CP, this change will occur around 30-40 years, with the risk of losing mobility increasing with age. This narrative review aims to first provide objective evidence of motor function and gait decline in adults with CP when ageing, and then to offer mechanistic hypotheses to explain those alterations. Many studies have compared individuals with CP to the typically developing population, yet the evolution with ageing has largely been understudied. Comorbid diagnoses comprise one of the potential determinants of motor function and gait decline with ageing in people with CP, with the first manifestations happening at an early age and worsening with ageing. Similarly, ageing appears to cause alterations to the neuromuscular and cardiovascular systems at an earlier age than their typically developing (TD) peers. Future studies should, however, try to better understand how the physiological particularities of CP change with ageing that could pave the way for better strategies for maintaining function and quality of life in people with CP.

Use of primary health care services among children and adolescents with cerebral palsy

AIM

To investigate the use of general practitioners and urgent care centres (UCC) among children and adolescents with cerebral palsy (CP) compared to a control group, and per gross motor function level.

METHOD

Data on children with CP born 1996 to 2014 were collected from the Norwegian Quality and Surveillance Registry for Cerebral Palsy. A control group was extracted from Statistics Norway. The date and diagnosis codes for general practitioner and UCC contacts from 2006 to 2015 were collected from the Norwegian Control and Payment of Health Reimbursement Database. Incidence rate ratios (IRR) for the number of contacts per person-year with 95% confidence intervals (CI) were calculated using Poisson regression. Risk differences with 95% CI were used to compare cumulative diagnosis incidences between children with CP and the control group.

RESULTS

The study included 2510 children (1457 males; 58.1%) with CP and 12 041 (7003 males; 58.2%) without CP (mean age in both groups 7 years 2 months, SD 4 years 8 months, range 0-19 years), with 336 250 contacts. Children with CP had more general practitioner (IRR 1.47; 95% CI 1.29-1.67) and UCC (IRR 1.30; 95% CI 1.13-1.50) contacts than children without CP, for all ages. IRRs remained unchanged when comparing children with CP in Gross Motor Function Classification System (GMFCS) levels I and II to children without CP. Among children with CP, contact increased as GMFCS levels increased, and they were in contact most often for respiratory and general and unspecified diagnoses. The risk for epilepsy was highest for those in contact with general practitioners.

INTERPRETATION

Children with CP, including those with less severe motor impairments, contacted general practitioners and UCCs more than children without CP. However, contact increased as gross motor impairment increased. They had contact for many diagnoses, mostly respiratory.

Nutritional status and neurodevelopmental levels in infants at high risk of cerebral palsy

Importance

Nutrition is associated with neurodevelopment. Infants at high risk of cerebral palsy (CP) usually suffer from undernutrition, yet the relationship between nutritional status and neurodevelopmental levels is unclear.

Objective

To describe the nutritional status characteristics of infants at high risk of CP, and to explore the relationship between neurodevelopmental levels and nutritional status.

Methods

This single-center cross-sectional study enrolled infants at high risk of CP, with corrected age from 0 days to 12 months. Weight and height were measured and calculated into z-scores, which were used to classify the nutritional status based on the World Health Organization growth charts and American Society for Parenteral and Enteral Nutrition standards. The Bayley Scales of Infant and Toddler Development were used to evaluate the developmental levels of gross motor, fine motor, cognition, receptive communication, and expressive communication.

Results

A total of 479 infants at high risk of CP were recruited, with 43.4% classified as undernutrition. Compared to those with normal neurodevelopment, the odds of moderate and severe undernutrition were about 1.8 and 3.9 times higher in gross motor delay, 2.2 and 3.1 times higher in fine motor delay, 2.5 and 9.4 times higher in cognition delay, 2.2 and 3.9 times higher in receptive communication delay, and 3.0 and 5.6 times higher in expressive communication delay. There were significant positive correlations between nutritional status and neurodevelopmental levels (P < 0.001).

Interpretation

Undernutrition and neurodevelopmental delays are prevalent among infants at high risk of CP. Worse nutritional status was correlated with lower neurodevelopmental levels.

Resilience and challenges: A qualitative exploration of Jordanian Mothers' experiences with children who have cerebral palsy

PURPOSE

This study aimed to explore the experiences of Jordanian mothers of children with cerebral palsy (CP) in order to better understand the challenges they face while caring for their children.

DESIGN AND METHODS

A qualitative descriptive study was applied, using semi-structured face to face interviews with a purposive sample of 10 mothers of children with CP.

FINDINGS

Mothers caring for children with CP embark on a challenging journey. Navigating the diagnosis begins with shock and disbelief, followed by emotional struggles as they deal with the new reality. This initial phase also involves caregiving challenges and hardships. Mothers may experience societal stigma and feelings of rejection, which can contribute to social isolation. Additionally, the physical demands of care can lead to financial hardships. These financial constraints can further limit access to specialized care, creating a frustrating cycle for mothers. Throughout this process, mothers demonstrate resilience by adapting to the illness. This encompasses making changes in their lives, actively seeking support, and developing expertise in managing their child's specific needs.

CONCLUSIONS

The results shed light on the emotional, physical, and social challenges faced by mothers of children with CP. The findings show a narrative of adaptation, resilience, and strength, encompassing adjustments to the diagnosis, substantial life changes, seeking support, and addressing challenges such as social stigma, isolation, and various hardships.

PRACTICE IMPLICATIONS

Our findings lay the foundation for tailored interventions and empathic support for mothers caring for a child with CP.

Advances in Cerebral Palsy Treatment

Background:

Cerebral palsy is a complex neurodevelopmental disorder with various etiological factors and treatment options. This narrative review aimed to summarize the causes of cerebral palsy, identify areas needing additional research in treatment approaches, and highlight areas requiring further investigation. In order to provide a thorough overview of management techniques to lessen the effects of the illness and its consequences, this review has drawn data from a number of studies.

Introduction:

Prematurity increases the risk of brain damage during the developing stage and accounts for a sizable fraction of cerebral palsy cases. In a sizable portion of cases, maternal diabetes and hypertension are listed as the main causes. Damage to the brain tissue results from hypoxic-ischemic injuries sustained during pregnancy that upset the equilibrium of oxidants and antioxidants. To alter the oxidative stress pathway and ease related issues, pharmacological treatments, such as therapeutic hypothermia, free radical inhibition therapy, and mitochondrial therapy, have been proposed. Therapeutic strategies, such as physiotherapy, occupational therapy, speech therapy, and surgical interventions, have added quality to the lives of the children. Some of the most recent developments in this area include the development of biomarkers for muscle activity detection, machine learning to predict the types of cerebral palsy and abnormal movements, disease prediction with eye images, wireless inertia measuring unit for spasticity detection, computerbased video analysis of typical and atypical infants, identification of intellectual disabilities with algorithms, and deep learning methods for predicting cerebral palsy.

Methods:

This narrative review is based on a careful analysis of numerous researches conducted on cerebral palsy, which have served as the basis for statistical distribution. It reviews the causes of cerebral palsy, available treatments, and ongoing research with the goal of providing physicians and researchers in the field with useful information. The objectives, study questions, inclusion criteria, and search approach have all been outlined in a thorough protocol. To find pertinent research published up to September 2021, a literature search was carried out using electronic databases, including Google Scholar, PubMed, Cochrane Library, Scopus, and Web of Science. A combination of pertinent keywords, such as "cerebral palsy," "management," "technology," "wearable technology," "prematurity," and "artificial intelligence," has been used in the search approach.

Results:

Recent advances in the field include the discovery of biomarkers for the detection of muscle activity, machine learning algorithms to predict the types of cerebral palsy and abnormal movements, disease prediction using eye images, wireless inertia measuring units for the detection of spasticity, computer-based video analysis for the detection of atypical infants, and algorithms to identify intellectual disabilities. Additionally, employing technologies, like virtual reality systems, electrical stimulators, activity trackers, machine learning, and deep learning approaches, has shown promise in evaluating, diagnosing, and predicting treatment outcomes linked to gait, upper limb, and lower limb function.

Conclusion:

Future research should examine the clinical application of nanomedicine, stem cell therapy, and cutting-edge therapeutic strategies to prevent hypoxic-ischemic damage in the developing brain. Additionally, research is required to effectively assist children with severe speech difficulties using alternate communication modalities and cutting-edge computational tools. The outcomes for people with cerebral palsy can be improved by combining interdisciplinary efforts with cutting-edge technological interventions.

Regional Disparities in Growth Patterns of Children with Cerebral Palsy: A Comparative Analysis of Saudi Arabian, UK, and US Data

AIM

In order to understand the global variations in the growth trajectories of cerebral palsy patients, this study aimed to compare the growth patterns of cerebral palsy patients in Saudi Arabi with United States and United Kingdom counterparts.

METHOD

Anthropometric data from 107 participants with cerebral palsy in Saudi Arabia were collected, including age, gender, cerebral palsy type, Gross Motor Function Classification System level, birth weight, weight at assessment, height at assessment, body mass index, and head circumference at assessment.

RESULTS

This study found discrepancies between the growth patterns of Saudi Arabian children with cerebral palsy and United Kingdom and the United States growth charts, particularly among those with severe cerebral palsy. Significant differences were observed in weight, height, and body mass index z-scores when comparing Saudi Arabian data with the United kingdom and United States reference data.

INTERPRETATION

These findings emphasize the importance of validating growth charts across different populations to ensure accurate monitoring and clinical management of children with cerebral palsy. Additionally, this study highlights the need for region-specific growth references to better address the diverse needs of individuals with cerebral palsy worldwide.

Randomised controlled trial of an online cognitive training program in school-aged children with cerebral palsy

BACKGROUND

Children with cerebral palsy (CP) experience deficits in nonverbal reasoning. The SMART online cognitive intervention has been associated with gains in IQ and nonverbal IQ in previous studies in typically developing school-aged children and children experiencing learning difficulties.

AIM

To assess the efficacy of an online cognitive intervention in school-aged children with CP.

METHODS AND PROCEDURES

21 children with CP (male n = 17; 76.2%), mean age 9 y 8 m, SD 1 y 1 month (range 8 y 3 m to 12 y 6 m) were randomised into the intervention group (n = 9) or a waitlist control group. A mixed-methods approach with an explanatory sequential design was used, with a randomised controlled trial followed by qualitative interviews. Participants were assessed on measures of intelligence, academic ability, attention and executive functioning, and social-emotional functioning at baseline, then after completing the training, or the waitlist period. Analyses included ANCOVAs and paired samples t tests. Semi-structured interviews explored participants' experiences with the training.

RESULTS AND OUTCOMES

Training completion was low with a mean of 16.9 modules completed out of 55 available. No significant effect of training was found for the primary outcome of intelligence, or for any secondary outcomes. Participants reported barriers and facilitators for accessing the program.

IMPLICATIONS

Cognitive training programs addressing relational framing ability may require significant modifications before they can be effectively tested with children with CP.

The power of Para sport: the effect of performance-focused swimming training on motor function in adolescents with cerebral palsy and high support needs (GMFCS IV) - a single-case experimental design with 30-month follow-up

OBJECTIVE

This study aims to evaluate the effect of a performance-focused swimming programme on motor function in previously untrained adolescents with cerebral palsy and high support needs (CPHSN) and to determine whether the motor decline typical of adolescents with CPHSN occurred in these swimmers.

METHODS

A Multiple-Baseline, Single-Case Experimental Design (MB-SCED) study comprising five phases and a 30-month follow-up was conducted. Participants were two males and one female, all aged 15 years, untrained and with CPHSN. The intervention was a 46-month swimming training programme, focused exclusively on improving performance. Outcomes were swim performance (velocity); training load (rating of perceived exertion min/week; swim distance/week) and Gross Motor Function Measure-66-Item Set (GMFM-66). MB-SCED data were analysed using interrupted time-series simulation analysis. Motor function over 46 months was modelled (generalised additive model) using GMFM-66 scores and compared with a model of predicted motor decline.

RESULTS

Improvements in GMFM-66 scores in response to training were significant (p<0.001), and two periods of training withdrawal each resulted in significant motor decline (p≤0.001). Participant motor function remained above baseline levels for the study duration, and, importantly, participants did not experience the motor decline typical of other adolescents with CPHSN. Weekly training volumes were also commensurate with WHO recommended physical activity levels.

CONCLUSIONS

Results suggest that adolescents with CPHSN who meet physical activity guidelines through participation in competitive swimming may prevent motor decline. However, this population is clinically complex, and in order to permit safe, effective participation in competitive sport, priority should be placed on the development of programmes delivered by skilled multiprofessional teams.

Chronic pain in children and young people with cerebral palsy: a narrative review of challenges, advances, and future directions

BACKGROUND

Cerebral palsy (CP), the most common physical disability of childhood, is often accompanied by a range of comorbidities including pain. Pain is highly prevalent in children and young people with CP, yet has been poorly understood, inaccurately assessed, and inadequately managed in this vulnerable population. This narrative review presents recent research advances for understanding and managing pain in children and young people with CP, focusing on chronic pain, and highlights future research directions.

MAIN BODY

Pain prevalence rates in CP vary due to different methodologies of studies. Recent systematic reviews report up to 85% of children experience pain; higher in older children, females, and those with dyskinesia and greater motor impairment. Research examining the lived experience perspectives of children and their families demonstrate that even those with mild motor impairments have pain, children want to self-report pain where possible to feel heard and believed, and management approaches should be individualized. Notably, many children with cognitive and communication impairments can self-report their pain if adjustments are provided and they are given a chance. Past inadequacies of pain assessment in CP relate to a focus on pain intensity and frequency with little focus on pain interference and coping, a lack of tools appropriate for the CP population, and an assumption that many children with cognitive and/or communication limitations are unable to self-report. Recent systematic reviews have identified the most reliable and valid assessment tools for assessing chronic pain. Many were not developed for people with CP and, in their current form, are not appropriate for the spectrum of physical, communication, and cognitive limitations seen. Recently, consensus and co-design in partnership with people with lived experience and clinicians have identified tools appropriate for use in CP considering the biopsychosocial framework. Modifications to tools are underway to ensure feasibility and applicability for the spectrum of abilities seen.

CONCLUSION

Recent research advances have improved our understanding of the prevalence, characteristics and lived experience of chronic pain, and refined assessment methods in children and young people with CP. However, the very limited evidence for effective and novel management of chronic pain in this population is where research should now focus.

Outpatient encounters, continuity of care, and unplanned hospital care for children and young people with cerebral palsy

AIM

To describe the relationships between outpatient encounters, continuity of care, and unplanned hospital care in children/young people with cerebral palsy (CP).

METHOD

In this population-based data-linkage cohort study we included children/young people with CP identified in the New South Wales/Australian Capital Territory CP Register (birth years 1994-2018). We measured the frequency of outpatient encounters and unplanned hospital care, defined as presentations to emergency departments and/or urgent hospital admissions (2015-2020). Continuity of outpatient care was measured using the Usual Provider of Care Index (UPCI).

RESULTS

Of 3267 children/young people with CP, most (n = 2738, 83.8%, 57.6% male) had one or more outpatient encounters (123 463 total encounters, median six outpatient encounters per year during childhood). High UPCI was more common in children/young people with mild CP (Gross Motor Function Classification System levels I-III, with no epilepsy or no intellectual disability), residing in metropolitan and areas of least socioeconomic disadvantage. Low UPCI was associated with four or more emergency department presentations (adjusted odds ratio [aOR] 2.34; 95% confidence interval [CI] 1.71-3.19) and one or more urgent hospital admissions (aOR 2.02; 95% CI 1.57-2.61).

INTERPRETATION

Children/young people with CP require frequent outpatient services. Improving continuity of care, particularly for those residing in regional/remote areas, may decrease need for unplanned hospital care.

WHAT THIS PAPER ADDS

Many children with cerebral palsy use multiple and frequent outpatient services. Better continuity of care is associated with living in metropolitan and less socioeconomically disadvantaged areas. Outpatient service utilization reduces at the time of transition to adult services. High outpatient utilization is associated with unplanned hospital care. Decreased continuity of care is associated with unplanned hospital care.

Reoperation, Readmission, and Postoperative Bleeding in Pediatric Cerebral Palsy Patients Undergoing Spinal Arthrodesis

Background Cerebral palsy (CP) is one of the most common neuromuscular disorders in children, and spinal abnormalities are vastly more common in people with CP compared to the general population. Further investigation is needed to improve our understanding of the perioperative factors that place children with CP at greater risk of postoperative complications. This study aims to investigate (1) whether pediatric CP patients have higher rates of postoperative complications after spinal fusion and (2) risk factors for postoperative bleeding, readmission, and reoperation. Methodology The 2019 American College of Surgeons National Surgical Quality Improvement Program Pediatric database was used for this study. Chi-square tests were used to compare patient demographics, frequency of comorbidities, intraoperative factors, and postoperative complications between CP and non-CP patients. Multivariable logistic regression modeling was conducted to determine if CP was an independent risk factor for the composite variable that included postoperative bleeding, readmission, and reoperation. Results A total of 4,445 patients were included in the study, with 606 CP and 3,839 non-CP patients. Several comorbidities were more prevalent in the CP cohort, most notably asthma, gastrointestinal disease, previous cardiac surgery, and hematologic disorders. Multivariable logistic regression modeling revealed that CP, older age, non-Caucasian race, American Society of Anesthesiologists (ASA) class of 3 or higher, posterior surgical approach, previous cardiac surgery, and ostomy were significantly correlated with higher postoperative complications. Conclusions This study demonstrates that CP, older age, non-Caucasian race, ASA class of 3 or higher, posterior approach, previous cardiac surgery, and ostomy are independent risk factors for postoperative complications, including readmission, reoperation, and postoperative bleeding requiring transfusions. Consequently, there is a pressing need for additional research to establish perioperative strategies that reduce postoperative risks for these patients. Spine surgeons should consider the findings of this study when communicating the potential risks of spinal fusion surgery with patients and their families.

Effects of Therapies Involving Plyometric-Jump Training on Physical Fitness of Youth with Cerebral Palsy: A Systematic Review with Meta-Analysis

The aim of this systematic review was to assess the effects of plyometric-jump training (PJT) on the physical fitness of youth with cerebral palsy (CP) compared with controls (i.e., standard therapy). The PRISMA 2020 guidelines were followed. Eligibility was assessed using the PICOS approach. Literature searches were conducted using the PubMed, Web of Science, and SCOPUS databases. Methodological study quality was assessed using the PEDro scale. Data were meta-analyzed by applying a random-effects model to calculate Hedges' g effect sizes (ES), along with 95% confidence intervals (95% CI). The impact of heterogeneity was assessed (I2 statistic), and the certainty of evidence was determined using the GRADE approach. Eight randomized-controlled studies with low-to-moderate methodological quality were included, involving male (n = 225) and female (n = 138) youth aged 9.5 to 14.6 years. PJT interventions lasted between 8 and 12 weeks with 2-4 weekly sessions. Compared with controls, PJT improved the muscle strength (ES = 0.66 [moderate], 95% CI = 0.36-0.96, p < 0.001, I2 = 5.4%), static (ES = 0.69 [moderate], 95% CI= 0.33-1.04, p < 0.001, I2 = 0.0%) and dynamic balance (ES = 0.85 [moderate], 95% CI = 0.12-1.58, p = 0.023, I2 = 81.6%) of youth with CP. Therefore, PJT improves muscle strength and static and dynamic balance in youth with CP compared with controls. However, more high-quality randomized-controlled trials with larger sample sizes are needed to provide a more definitive recommendation regarding the use and safety of PJT to improve measures of physical fitness.

Exploring early life social and executive function development in infants and risk for autism: a prospective cohort study protocol of NICU graduates and infants at risk for cerebral palsy

BACKGROUND

Delays in early social and executive function are predictive of later developmental delays and eventual neurodevelopmental diagnoses. There is limited research examining such markers in the first year of life. High-risk infant groups commonly present with a range of neurodevelopmental challenges, including social and executive function delays, and show higher rates of autism diagnoses later in life. For example, it has been estimated that up to 30% of infants diagnosed with cerebral palsy (CP) will go on to be diagnosed with autism later in life.

METHODS

This article presents a protocol of a prospective longitudinal study. The primary aim of this study is to identify early life markers of delay in social and executive function in high-risk infants at the earliest point in time, and to explore how these markers may relate to the increased risk for social and executive delay, and risk of autism, later in life. High-risk infants will include Neonatal Intensive Care Unit (NICU) graduates, who are most commonly admitted for premature birth and/or cardiovascular problems. In addition, we will include infants with, or at risk for, CP. This prospective study will recruit 100 high-risk infants at the age of 3-12 months old and will track social and executive function across the first 2 years of their life, when infants are 3-7, 8-12, 18 and 24 months old. A multi-modal approach will be adopted by tracking the early development of social and executive function using behavioural, neurobiological, and caregiver-reported everyday functioning markers. Data will be analysed to assess the relationship between the early markers, measured from as early as 3-7 months of age, and the social and executive function as well as the autism outcomes measured at 24 months.

DISCUSSION

This study has the potential to promote the earliest detection and intervention opportunities for social and executive function difficulties as well as risk for autism in NICU graduates and/or infants with, or at risk for, CP. The findings of this study will also expand our understanding of the early emergence of autism across a wider range of at-risk groups.

Increasing Prevalence of Cerebral Palsy Among Two-Year-Old Children Born at <27 Weeks of Gestation: A Cohort Study

OBJECTIVE

To evaluate changes in prevalence and severity of cerebral palsy (CP) among surviving children born at <27 weeks of gestation over time and to determine associations between CP and other developmental domains, functional impairment, medical morbidities, and resource use among 2-year-old children who were born extremely preterm.

STUDY DESIGN

Retrospective cohort study using prospective registry data, conducted at 25 centers of the Eunice Kennedy Shriver National Institute of Child Health and Human Development Neonatal Research Network. Participants were children born at <27 weeks of gestation and followed at 18 through 26 months of corrected age from 2008 through 2019. Outcomes of interest were changes in prevalence of any CP and severity of CP over time and associations between CP and other neurodevelopmental outcomes, functional impairment, and medical comorbidities. Adjusted logistic, linear, multinomial logistic, and robust Poisson regression evaluated the relationships between child characteristics, CP severity, and outcomes.

RESULTS

Among 6927 surviving children with complete follow-up data, 3717 (53.7%) had normal neurologic examinations, 1303 (18.8%) had CP, and the remainder had abnormal neurologic examinations not classified as CP. Adjusted rates of any CP increased each year of the study period (aOR 1.11 per year, 95% CI 1.08-1.14). Cognitive development was significantly associated with severity of CP. Children with CP were more likely to have multiple medical comorbidities, neurosensory problems, and poor growth at follow-up.

CONCLUSIONS

The rate of CP among surviving children who were born extremely preterm increased from 2008 through 2019. At 18 to 26 months of corrected age, neurodevelopmental and medical comorbidities are strongly associated with all severity levels of CP.

Understanding the use and benefits of assistive devices among young children with cerebral palsy and their families in Norway: a cross-sectional population-based registry study

PURPOSE

Assistive technology intervention has become an important strategy in enhancing function in young children with cerebral palsy. This study aimed to provide an in-depth knowledge of the use of assistive devices by describing their purposes, the environments in which they are used, frequency of use and perceived benefits from the caregiver's perspective.

MATERIAL AND METHODS

This is a cross-sectional population-based study using data from national cerebral palsy registers in Norway. Of a total of 202 children, 130 participated (mean age 49.9 months, SD 14.0 months).

RESULTS

The 130 children and their families used a median of 2.5 assistive devices (range 0-12) to support positioning, mobility, self-care and training, stimulation and play. Devices most commonly had one or two main purposes and were used both at home and in kindergarten/school. The usage rate varied from less than twice a week to several times a day. The majority of parents reported significant benefits for caregiving and/or the child's functioning. Total use increased in accordance with the level of the child's gross motor limitations and was associated with restrictions imposed by housing concerns.

CONCLUSIONS

The frequent use of a wide range of devices, and the intended and perceived benefits, demonstrates that early provision of assistive devices can be an effective function-enhancing strategy in young children with cerebral palsy. However, the findings also indicate that factors others than the child's motor abilities must be considered when integrating the use of devices into the child's daily routines and activities.

Cerebral Palsy Heterogeneity: Clinical Characteristics and Diagnostic Significance from a Large-Sample Analysis

INTRODUCTION

Cerebral palsy (CP) is a nonprogressive movement disorder resulting from a prenatal or perinatal brain injury that benefits from early diagnosis and intervention. The timing of early CP diagnosis remains controversial, necessitating analysis of clinical features in a substantial cohort.

METHODS

We retrospectively reviewed medical records from a university hospital, focusing on children aged ≥24 months or followed up for ≥24 months and adhering to the International Classification of Diseases-10 for diagnosis and subtyping.

RESULTS

Among the 2012 confirmed CP cases, 68.84% were male and 51.44% had spastic diplegia. Based on the Gross Motor Function Classification System (GMFCS), 62.38% were in levels I and II and 19.88% were in levels IV and V. Hemiplegic and diplegic subtypes predominantly fell into levels I and II, while quadriplegic and mixed types were mainly levels IV and V. White matter injuries appeared in 46.58% of cranial MRI findings, while maldevelopment was rare (7.05%). Intellectual disability co-occurred in 43.44% of the CP cases, with hemiplegia having the lowest co-occurrence (20.28%, 58/286) and mixed types having the highest co-occurrence (73.85%, 48/65). Additionally, 51.67% (697/1,349) of the children with CP aged ≥48 months had comorbidities.

CONCLUSIONS

This study underscores white matter injury as the primary CP pathology and identifies intellectual disability as a common comorbidity. Although CP can be identified in infants under 1 year old, precision in diagnosis improves with development. These insights inform early detection and tailored interventions, emphasizing their crucial role in CP management.

Association of epilepsy with neuroimaging patterns in children with cerebral palsy

OBJECTIVES

In this study, we examined whether epilepsy and drug-resistant epilepsy are associated with neuroimaging findings in children with cerebral palsy (CP).

METHODS

Magnetic resonance imaging classification system (MRICS) proposed by Surveillance of Cerebral Palsy in Europe (SCPE) was used for classification of different MRI patterns in patients with cerebral palsy. We reviewed the brain MRI scans and medical records of children with CP who were followed-up in our clinic between 2019 and 2023. Patients were divided into three categories: CP without epilepsy, CP with controlled epilepsy and CP with DRE. MRI patterns were grouped as maldevelopments, predominant white matter injury, predominant gray matter injury, miscellaneous (delayed myelination, cerebral atrophy, cerebellar atrophy, brainstem lesions and calcifications, lesions that were not classified under any other group) and normal according to MRICS of the SCPE.

RESULTS

There were 325 CP patients. The most common MRI patterns were predominant white matter injury (47.6%) and gray matter injury (23.8%). There was a 1.5-fold reduction in the risk of epilepsy in patients with predominant white matter injury (OR = 1.54, 95% CI 1.23-1.94). In contrast, children in the miscellaneous group had significantly higher risks of epilepsy (p < 0.001), and we were able to determine that miscellaneous findings increased the risk by 1.8 times (OR = 1.77, 95% CI 1.47-2.12).

CONCLUSION

In conclusion, more than half of the children with CP had epilepsy, 40.7% of whom had DRE. On MRI, miscellaneous findings may indicate a poor prognosis for epilepsy, while predominant white matter injury may indicate a good outcome. Children with CP, especially those with miscellaneous findings on MRI, should be closely monitored for epilepsy development.

The cost of respiratory hospitalizations in children with cerebral palsy

AIM

To establish the burden of respiratory illness in cerebral palsy (CP) on the Western Australian health care system by quantifying the costs of respiratory hospitalizations in children with CP, compared with non-respiratory hospitalizations.

METHOD

A 2-year (2014-2015) retrospective study using linked hospital data (excluding emergency department visits), in a population of children with CP in Western Australia aged 18 years and under (median age at hospitalization 7 years; interquartile range 5-12 years).

RESULTS

In 671 individuals (57% male) there were 726 emergency hospitalizations, and 1631 elective hospitalizations. Although there were more elective hospitalizations, emergency hospitalizations were associated with longer stays in hospital, and more days in an intensive care unit, resulting in a higher total cost of emergency hospitalizations than elective hospitalizations (total costs: emergency AU$7 748 718 vs elective AU$6 738 187). 'Respiratory' was the leading cause of emergency hospitalizations, contributing to 36% of all emergency admission costs. For a group of high-cost inpatient users (top 5% of individuals with the highest total inpatient costs) the most common reason for hospitalization was 'respiratory'. Where non-respiratory admissions were complicated by an additional respiratory diagnosis, length of stay was greater.

INTERPRETATION

Respiratory hospitalizations in CP are a significant driver of health care costs. In the paediatric group, they are a burden for a subgroup of children with CP.

WHAT THIS PAPER ADDS

Respiratory illness is the most costly area for unplanned, emergency hospitalizations for children and young people with cerebral palsy. The top 5% of individuals with the highest total inpatient costs account for a disproportionate amount of health care costs.

Opioid prescription patterns among commercially insured children with and without cerebral palsy

PURPOSE

This study aimed to describe opioid prescription patterns for children with vs. without cerebral palsy (CP).

METHODS

This cohort study used commercial claims from 01/01/2015-12/31/2016 and included children aged 2-18 years old with and without CP. Opioid prescription patterns (proportion exposed, number of days supplied) were described. A zero-inflated generalized linear model compared the proportion exposed to opioids in the follow-up year (2016) and, among those exposed, the number of days supplied opioids between cohorts before and after adjusting for age, gender, race, U.S. region of residence, and the number of co-occurring neurological/neurodevelopmental disabilities (NDDs).

RESULTS

A higher proportion of children with (n = 1,966) vs. without (n = 1,219,399) CP were exposed to opioids (12.1% vs. 5.3%), even among the youngest age group (2-4 years: 9.6% vs. 1.8%), and had a greater number of days supplied (median [interquartile range], 8 [5-13] vs. 6 [4-9] days; P < 0.05). Comparing children with opioid exposure with vs. without CP, a greater number of days supplied was identified for older age, Asian race/ethnicity, and without co-occurring NDDs, and a lower number of days supplied was observed for Black race/ethnicity and with ≥1 co-occurring NDDs.

CONCLUSION

Children with CP are more likely to be exposed to opioids and have a higher number of days supplied.

"It starts with a knock on the door": Caregiver and provider perspectives on healthcare communication for youth with intellectual and developmental disabilities

OBJECTIVES

Effective healthcare communication (HCC) is critical for youth with intellectual and developmental disabilities (IDD) who may have complex healthcare needs. The goal of this study was to gain family caregiver and provider perspectives on facilitators and challenges to effective HCC for youth with IDD.

METHODS

Caregivers of, and providers for youth with IDD were recruited from the community to participate in virtual focus group (FG) sessions. FGs were 60-90 min long and were facilitated by a research team consisting of caregivers and providers. The FGs were recorded, transcribed, and coded inductively for HCC themes.

RESULTS

Nineteen stakeholders participated in the FGs (caregivers: n = 14; providers: n = 5). Twenty-three themes were coded from the transcripts and were categorized by whether they focused on providers, caregivers, or healthcare systems.

CONCLUSIONS

Provider behaviors such as active listening and demonstrating humility were found to be critical for effective HCC. Fewer caregiver factors, such as advocacy, and systems factors such as visit format, emerged from the FG data. FG themes represent challenges that future interventions must address.

PRACTICE IMPLICATIONS

Efforts to improve HCC, and thus healthcare outcomes for youth with IDD, should address challenges identified by caregivers and providers.

How did youth with cerebral palsy perceive participation in everyday life after participating in a periodical intensive rehabilitation program based on adapted physical activity in groups? A qualitative interview study

PURPOSE

Explore how youths with CP experience participation in everyday life, their experience of having participated in a periodical intensive rehabilitation programme and their expectations for the future.

MATERIALS & METHODS

A qualitative design that included semi-structured interviews with 14 youths with CP (mean age 17 years).

RESULTS

The qualitative content analysis exposed six themes, (1) Everyday life - to get the pieces of your life to fit together, (2) Participation means inclusion and belonging - the meaning of life, (3) Individual and environmental factors influencing participation, (4) Experience of physical and social activities away from home together with like-minded people, (5) To be continued locally, and (6) You do not know the future, anything can happen - visions for the future.

CONCLUSIONS

Participation in everyday life increases the meaning of life but takes energy. Periodical intensive rehabilitation programme enabled youths to try new activities, make friends and increase self-insight in their own strengths and limitations.IMPLICATIONS FOR REHABILITATIONYoung people with cerebral palsy (CP) describe participation as the meaning of life and state that it is essential for inclusion and being able to contribute to societyAdaptation of environmental factors including collaboration across service sectors and capacity building in young people within their preferred life situations appear to be essentialA periodical intensive rehabilitation, including adapted physical activities in groups, is recommended to provide peer learning and mastery experiences in young people with CP.Young people with CP seem to have the same hopes for the future as their typically developing peers.

Assessing the reliability and validity of a health-related quality of life instrument, CPADULT, in a Dutch sample of adults with severe disabilities who are non-ambulatory

BACKGROUND

A measure to provide insight regarding health-related quality of life of adults with severe motor and intellectual disabilities was lacking. For this reason, the CPADULT was developed. This measure includes domains relating to an individual's physical, mental, and social functioning. The purpose of this study was to assess the psychometric characteristics of the CPADULT.

METHOD

Caregivers (n = 47; 77% female, 23% male) of individuals with severe disabilities who are non-ambulatory completed the questionnaire. Internal consistency, test-retest reliability and construct validity were analysed.

RESULTS

Internal consistency was adequate with Cronbach's alpha values from 0.75 to 0.95. Test-retest reliability was good, as intraclass correlation coefficient of the total score was 0.84 (domains: 0.61-0.89). Construct validity was confirmed with significant differences between subgroups of motor or intellectual abilities.

CONCLUSION

The CPADULT has sufficient reliability and validity as a proxy measure of health-related quality of life for adults with severe disabilities who are non-ambulatory.

The critical need to accelerate cerebral palsy research with consumer engagement, global networks, and adaptive designs

The prevalence of cerebral palsy (CP) varies globally, with higher rates and burden of disease in low- and middle-income countries. CP is a lifelong condition with no cure, presenting diverse challenges such as motor impairment, epilepsy, and mental health disorders. Research progress has been made but more is needed, especially given consumer demands for faster advancements and improvements in the scientific evidence base for interventions. This paper explores three strategies to accelerate CP research: consumer engagement, global clinical trial networks, and adaptive designs. Consumer engagement involving individuals with lived experience enhances research outcomes. Global clinical trial networks provide efficiency through larger and more diverse participant pools. Adaptive designs, unlike traditional randomized controlled trials, allow real-time modifications based on interim analyses, potentially answering complex questions more efficiently. The establishment of a CP Global Clinical Trials Network, integrating consumer engagement, global collaboration, and adaptive designs, marks a paradigm shift. The Network aims to address consumer-set research priorities. While challenges like ethical considerations and capacity building exist, the potential benefits for consumers, clinicians, researchers, and funding bodies are substantial. This paper underscores the urgency of transforming CP research methodologies for quicker translation of novel treatments into clinical practice to improve quality of life for those with CP.

Provision of augmentative and alternative communication interventions to Norwegian preschool children with cerebral palsy: are the right children receiving interventions?

Preschool children with cerebral palsy (CP) with no or unintelligible speech need augmentative and alternative communication (AAC), but not all children needing AAC have access to it. This study describes the use and perceived benefit of AAC and explores factors associated with receiving AAC interventions. Using a cross-sectional design, we combined parent-reported data with data from the Norwegian Quality and Surveillance Registry for Cerebral Palsy (NorCP). Communication, speech and hand function was classified according to the Communication Function Classification System (CFCS), Viking Speech Scale (VSS), and Manual Ability Classification System (MACS), accordingly. The need for AAC was defined as Levels III-V on the CFCS, without simultaneous classification at VSS Level I, and/or Levels III-IV on VSS. Parents reported on child- and family-directed AAC interventions using the Habilitation Services Questionnaire. Of the 95 children (42 females) with CP (M = 39.4 months, SD = 10.3), 14 had communication aids. Of the 35 children (31.4%) defined as needing AAC, 11 had been provided with communication aids. Parents of children with a communication aid reported satisfaction with and frequent use of the aid. Children at MACS Level III-V (OR = 3.4, p = .02) or with epilepsy (OR = 8.9, p < .01) were most likely to have received an AAC intervention. The low proportion of children receiving communication aids indicates an unmet need for AAC interventions among preschool children with CP.

Risk Factors of Infectious Complications in Pediatric Patients With Cerebral Palsy After Spinal Arthrodesis

STUDY DESIGN

This was a retrospective study.

OBJECTIVE

The main objective of this study was to investigate (1) whether pediatric patients with cerebral palsy (CP) have higher rates of postoperative infectious complications after spinal fusion and (2) risk factors for postoperative infections.

SUMMARY OF BACKGROUND DATA

Prior studies have shown that patients with CP undergo corrective spine surgery more often than the general population, yet typically have worse postoperative outcomes. Further investigation is needed to improve our understanding of the perioperative factors that place children with CP at greater risk of postoperative infectious complications.

PATIENTS AND METHODS

The 2019 "American College of Surgeons National Surgical Quality Improvement Program" Pediatric database was used for patient data. The univariable analysis compared the prevalence of preoperative comorbidities and perioperative factors between children with and without CP. Multivariable logistic regression modeling was used to ascertain independent risk factors for postoperative infectious complications.

RESULTS

A total of 4445 patients were included in the study; 606 (13.63%) patients had CP and 3839 (86.37%) did not. Patients with CP were more likely to have several notable preoperative comorbidities, and the rate of developing any infectious complication was more than 7 times greater in the CP cohort than in the control cohort (14.36% vs 1.88%; P <0.001). Multivariable analysis revealed CP [odds ratio (OR): 3.55, CI: 2.25-5.60; P <0.001], American Society of Anesthesiologists class 3 or higher (OR: 2.10, CI: 1.29-3.42; P = 0.003), and hematologic disorders (OR: 2.01, CI: 1.06-3.83; P = 0.033) to be independent risk factors for increased postoperative infectious complications.

CONCLUSIONS

CP is an independent risk factor for the development of 30-day postoperative infectious complications in pediatric patients. In addition, the American Society of Anesthesiologists class 3 or higher and hematologic disorders were risk factors for postoperative infections after spinal fusion surgery.

The effect of functional independence levels on sleep and constipation in children with cerebral palsy

OBJECTIVE

The study aimed to examine the effect of functional independence levels on sleep behavior and constipation in children with cerebral palsy.

METHODS

This cross-sectional observational single-center study was carried out in a special rehabilitation center in Istanbul. Inclusion criteria were those aged between 4 and 18 years with Gross Motor Function Classification System III-IV-V functional independence levels. Those who had surgery concerning intestinal health, had a chronic infectious bowel disease, had congenital intestinal anomalies, had received botox treatment in the last 6 months, had uncontrolled epileptic seizures, had complained of constipation in the last 6 months, and had cardiopulmonary disease were excluded from the study. The sociodemographic characteristics of the participants and the Gross Motor Function Classification System were recorded. Pediatric Functional Independence Scale (Functional Independence Measure for Children) was used to measure the functional independence level, Pediatric Sleep Questionnaire was used to measure the level of sleep problems, and Constipation Severity Scale was used to measure constipation severity.

RESULTS

A total of 60 children who were diagnosed with cerebral palsy were included. According to Gross Motor Function Classification System, 46.7% of the cases were Level III, 35% were Level IV, and 18.3% were Level V. There was a negative moderate significant correlation between Functional Independence Measure for Children and Pediatric Sleep Questionnaire (r=-0.303; p=0.019) and between Functional Independence Measure for Children and Constipation Severity Scale (r=-0.342; p=0.007).

CONCLUSION

We described that lower functional independence levels were related to worse sleep and constipation symptoms. The results suggest that effective strategies for developing functional independence levels may be beneficial for both sleep and constipation symptoms in the concept of cerebral palsy management.

Association between Cu/Zn/Iron/Ca/Mg levels and cerebral palsy: a pooled-analysis

It was well documented that macro/trace elements were associated with the neurodevelopment. We aimed to investigate the relationship between copper (Cu)/zinc (Zn)/iron/calcium (Ca)/magnesium (Mg) levels and cerebral palsy (CP) by performing a meta-analysis. We searched the PubMed, Embase, Cochrane and Chinese WanFang databases from January 1985 to June 2022 to yield studies that met our predefined criteria. Standard mean differences (SMDs) of Cu/Zn/Iron/Ca/Mg levels between CP cases and healthy controls were calculated using the fixed-effects model or the random-effects model, in the presence of heterogeneity. 95% confidence intervals (CI) were also computed. Sensitivity analysis was performed by omitting each study in turn. A total of 19 studies were involved in our investigation. CP cases showed markedly lower Cu, Zn, iron and Ca levels than those in controls among overall populations (SMD =  - 2.156, 95% CI - 3.013 to - 1.299, P < 10-4; SMD =  - 2.223, 95% CI - 2.966 to - 1.480, P < 10-4; SMD =  - 1.092, 95% CI - 1.513 to - 0.672, P < 10-4; SMD =  - 0.757, 95% CI - 1.475 to - 0.040, P = 0.038) and Asians (SMD =  - 2.893, 95% CI - 3.977 to - 1.809, P < 10-4; SMD =  - 2.559, 95% CI - 3.436 to - 1.683, P < 10-4; SMD =  - 1.336, 95% CI - 1.807 to - 0.865, P < 10-4; SMD =  - 1.000, 95% CI - 1.950 to - 0.051, P = 0.039). CP cases showed markedly lower Zn level than that in controls among Caucasians (SMD =  - 0.462, 95% CI - 0.650 to - 0.274, P < 10-4). No significant differences of Cu, iron and Ca levels between CP cases and controls among Caucasians (SMD =  - 0.188, 95% CI - 0.412 to 0.037, P = 0.101; SMD =  - 0.004, 95% CI - 0.190 to 0.182, P = 0.968; SMD = 0.070, 95% CI - 0.116 to 0.257, P = 0.459) were observed. No marked difference of Mg level between CP cases and controls was noted among overall populations (SMD =  - 0.139, 95% CI - 0.504 to 0.226, P = 0.455), Asians (SMD =  - 0.131, 95% CI - 0.663 to 0.401, P = 0.629), and Caucasians (SMD =  - 0.074, 95% CI - 0.361 to 0.213, P = 0.614). Sensitivity analysis did not change the overall results significantly for Cu, Zn, iron and Mg. CP cases demonstrated significantly lower levels of Cu/Zn/iron/Ca than those in healthy controls, particularly in Asians. Decreasing trend of Cu/Zn/iron/Ca levels merit attention, particularly in the population with high susceptibility to CP. Frequent monitoring and early intervention may be needed.

Characteristics of Children with Cerebral Palsy and Their Utilization of Services in Saudi Arabia

The recent emergence of research on cerebral palsy (CP) in developing countries aims to improve knowledge on affected children and the utilization of the available services. This study seeks to describe children with CP in Saudi Arabia and service utilization as per Gross Motor Function Classification System (GMFCS) levels and geographic regions. A cross-sectional survey of 227 children with CP (Mean age 6.3, SD 3.9 years) was conducted. Parents reported on children's demographics, impairments, and service utilization. Half of the children (n = 113, 49.8%) had ≥3 impairments with speech, visual and learning impairments being the most frequent. The total number of impairments differed significantly by GMFCS, F (4, 218) = 8.87, p < 0.001. Most of the children (n = 86, 83.4%) used 2-5 services. Moreover, 139 (62.3%) did not attend school, 147 (65.9%) did not receive occupational therapy, and only 32 (14.3%) received speech therapy. More children in GMFCS level I did not receive neurologist services. Profiles of children and services were described by GMFCS and by regions. This was the first study to describe children with CP and service utilization in Saudi Arabia. Although many impairments affected the children, there was low utilization of related services. Data on service utilization and on unmet needs support a comprehensive approach to rehabilitation and the proper service allocation.

Prevalence of cerebral palsy comorbidities in China: a systematic review and meta-analysis

Objectives

This systematic review aimed to comprehensively understand the comorbidity of cerebral palsy (CP) in China.

Methods

We searched through databases in both Chinese and English until December 2022 to gather cross-sectional studies on the comorbidity of CP in China. After two reviewers independently screened the articles, collected the data, and assessed the bias risk, a meta-analysis was conducted using the Stata 17.0 software.

Results

A total of 73 articles were included. Of these, 16 articles reported total comorbidity, with a prevalence of 79.7% (95% CI: 73.8-85.7%); 56 articles reported epilepsy, with a prevalence of 17.9% (95% CI: 15.4-20.4%); 48 articles reported intellectual disability, with a prevalence of 58.0% (95% CI: 51.8-64.3%); 32 articles reported speech disorders, with a prevalence of 48.0% (95% CI: 41.6-54.4%); 41 articles reported hearing disorders, with a prevalence of 17.2% (95% CI: 13.0-21.4%); and 35 articles reported vision disorders, with a prevalence of 23.1% (95% CI: 16.3-29.8%). The topographical type of CP was the primary source of heterogeneity in the prevalence of epilepsy. Diagnostic criteria for CP, clinical type of CP, GMFCS, publishing time, and topographical type of CP were the primary sources of heterogeneity in the prevalence of intellectual disability. Clinical type of CP and topographical type were the primary sources of heterogeneity in the prevalence of speech disorders. Finally, the region was the primary source of heterogeneity in the prevalence of hearing disorders.

Conclusion

The prevalence of comorbidities in CP is high in China. Comorbidities are related to the characteristics, severity, and risk factors of brain insult and have a particular relationship with regional economic development and medical and health levels.
