Multimorbidity in Middle-Aged Adults with Cerebral Palsy

Adults with cerebral palsy and functional decline: A cross-sectional analysis of patient-reported outcomes from a novel North American registry

BACKGROUND

Adults with cerebral palsy (CP) have unique healthcare needs and risks, including high risk of functional decline. Understanding functional decline is an area of priority for CP research.

OBJECTIVE

Describe factors associated with patient-reported changes in function among adults with CP living in the community.

METHODS

Cross-sectional analysis of adult patient-reported outcomes collected by the CP Research Network (CPRN) Community Registry.

RESULTS

Participants included 263 respondents (76% female (n = 200); mean age 42 years (SD 14); 95% White (n = 249); 92% non-Hispanic (n = 241)). Many reported functional changes, most commonly a decline in gross motor function since childhood (n = 158, 60%). Prevalence of gross motor decline varied significantly by Gross Motor Function Classification System (GMFCS) level (p < 0.001), but neither hand function decline (p = 0.196) nor communication decline (p = 0.994) differed by GMFCS. All types of decline increased with increasing age, with statistically significant differences between age groups (p < 0.001 gross motor; p = 0.003 hand function; p = 0.004 communication). Those with spastic CP (n = 178) most commonly reported gross motor functional decline (n = 108/178, 60.7%). However, the prevalence of gross motor decline did not significantly differ between those with spastic CP and those without spastic CP (p = 0.789).

CONCLUSIONS

Many adults in the CPRN Community Registry reported functional decline, most commonly in gross motor function. Functional decline across domains increased with age. Further research into risk stratification and preventive and rehabilitative measures is needed to address functional decline across the lifespan.

The Prevalence and Risk Analysis of Cerebral Palsy and Other Neuro-Psychological Comorbidities in Children with Low Birth Weight in Taiwan: A Nationwide Population-Based Cohort Study

Background: This study evaluated early childhood comorbidities of cerebral palsy (CP) in low birth weight (LBW) children and assessed the impact of maternal bio-psychosocial factors on CP risk in preterm infants of varying birth weights (BWs). Methods: Data from 15,181 preterm infants (2009-2013) and 151,810 controls were analyzed using Taiwan's National Health Insurance Research Database. CP prevalence and LBW-associated comorbidities were examined, and odds ratios (ORs) were calculated. Results: This study confirmed increasing prematurity and LBW rates in Taiwan, with LBW infants showing higher CP prevalence. Significant maternal risk factors included age extremes (<20 and >40 years). LBW infants exhibited higher risks for respiratory, circulatory, nervous system, and psycho-developmental comorbidities compared with controls, with the lowest BW having even higher ORs. Maternal factors such as family income, the number of hospital admissions, and length of hospital stay were remarkably correlated with BW and subsequent complications. Each additional gestational week crucially reduced the risk of complications in premature infants. Conclusions: LBW infants are at a higher risk for CP and various comorbidities, with maternal bio-psychosocial factors playing a critical role. Addressing these factors in prenatal care and interventions is essential to improve outcomes for premature infants.

Comorbidity Clusters Among Adults With Cerebral Palsy: A Latent Class Analysis

INTRODUCTION

Adults with cerebral palsy are at risk for early multimorbidity onset, but little is known about the composition of multimorbidity profiles or how these profiles present across adulthood. The objective of this study was to identify multimorbidity profiles and association with mortality among adults with cerebral palsy.

METHODS

This retrospective cohort study used a random 20% fee-for-service Medicare database from January 1, 2008 to December 31, 2019 from adults aged ≥18 years with cerebral palsy. Latent class analyses using 4-class models were conducted within each age cohort (young adults aged 18-39 years, middle adulthood aged 40-64 years, and older adults aged ≥65 years) to determine patterns of 30 comorbidities defined using the International Classification of Diseases, Ninth Revision codes, identified from January 1, 2008 to December 31, 2010, and their association with mortality through December 31, 2019 (up to 11 years of follow-up); statistical analysis was performed in 2023.

RESULTS

Three classes were relatively consistent in the composition of comorbidities across young (n=7,020), middle (n=13,554), and older (n=4,193) cohorts: (1) low morbidity (low proportion of all comorbidities) representing 50.1% (young), 41.4% (middle), and 30.9% (older) of the cohorts; (2) neurologic multimorbidity (e.g., epilepsy, intellectual disabilities) representing 26.0% (young), 26.6% (middle), and 14.7% (older) of the cohorts; and complex multimorbidity (e.g., cardiorespiratory, nutritional, musculoskeletal, neurologic) representing 26.0% (young), 26.6% (middle), and 14.7% (older) of the cohorts. The fourth class varied by young (mental health disorders), middle (hypertension), and older (hypertension and osteoarthritis) age cohorts. Compared with the low morbidity class, other classes had an increased mortality rate for each age cohort (hazard ratio range=1.34-5.58, all p<0.001).

CONCLUSIONS

Findings provide insight into varied multimorbidity profiles and associations with mortality across the life course for adults with cerebral palsy.

A pilot study proposing an algorithm for pubertal induction in cerebral palsy

OBJECTIVES

To explore delayed puberty in cerebral palsy (CP) and to test the acceptability of an interventional puberty induction algorithm.

METHODS

A two phase cohort study in children and adolescents diagnosed with CP who have delayed puberty. Phase 1: Retrospective review of clinical records and interviews with patients who have been treated with sex-steroids and Phase 2: Prospective interventional trial of pubertal induction with a proposed algorithm of transdermal testosterone (males) or oestrogen (females). Phase 1 examined experiences with sex-steroid treatment. Phase 2 collected data on height adjusted bone mineral density (BMAD), fractures, adverse effects, mobility and quality of life over two years during the induction.

RESULTS

Phase 1, treatment was well tolerated in 11/20 treated with sex-steroids; phase 2, using the proposed induction algorithm, 7/10 treated reached Tanner stage 3 by nine months. One participant reached Tanner stage 5 in 24 months. Mean change in BMAD Z-scores was +0.27 % (SD 0.002) in those who could be scanned by dual-energy X-ray absorptiometry (DXA).

CONCLUSIONS

Delayed puberty may be diagnosed late. Treatment was beneficial and well tolerated, suggesting all patients with severe pubertal delay or arrest should be considered for sex hormone supplementation.

Measuring grip strength in adolescents and adults with cerebral palsy in a clinic setting: Feasibility, reliability, and clinical associations

AIM

To determine the feasibility and reliability of measuring grip strength and its association with anthropometrics and diseases among adolescents and adults (≥16 years old) with cerebral palsy (CP).

METHOD

In this cross-sectional study, individuals with CP, classified in Gross Motor Function Classification System (GMFCS)/Manual Ability Classification System (MACS) levels I to V, were recruited to measure grip strength, anthropometrics, and self-reported current/history of disease during a routine clinical visit. Feasibility was determined as the proportion recruited/consented/completed testing. Test-retest reliability of three maximal effort trials per side was assessed. Linear regression determined associations of grip strength with anthropometrics after adjusting for age, sex, and GMFCS. The predictive ability of GMFCS alone, grip strength alone, GMFCS + grip strength, and GMFCS × grip strength for diseases was compared.

RESULTS

Of 114 individuals approached, 112 participated and 111 successfully completed all tasks. There was good to excellent reliability of test-retest grip strength between trials for dominant and non-dominant sides for the entire cohort and when stratified by each GMFCS and MACS level (intraclass correlation coefficient range 0.83-0.97). Sex, GMFCS, MACS, body mass, and waist circumference were associated with grip strength (p < 0.05), but not hip circumference, waist:hip ratio, or triceps skinfold thickness. Modeling grip strength with GMFCS had a higher predictive value for relevant diseases than GMFCS alone.

INTERPRETATION

Grip strength is a feasible and reliable measurement for CP, and is associated with some demographics and anthropometric measures. Grip strength, in addition to the GMFCS, enhanced prediction of disease outcomes.

WHAT THIS PAPER ADDS

Measurement of hand grip strength is clinically feasible for adolescents/adults with cerebral palsy. Grip strength has good to excellent test-retest reliability across Gross Motor Function Classification System (GMFCS) and Manual Ability Classification System (MACS) levels. Grip strength is associated with sex, weight, waist circumference, GMFCS, and especially MACS. Grip strength, in addition to GMFCS, shows promise for enhancing disease prediction in this cohort.

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.

Accurate Monitoring of 24-h Real-World Movement Behavior in People with Cerebral Palsy Is Possible Using Multiple Wearable Sensors and Deep Learning

Monitoring and quantifying movement behavior is crucial for improving the health of individuals with cerebral palsy (CP). We have modeled and trained an image-based Convolutional Neural Network (CNN) to recognize specific movement classifiers relevant to individuals with CP. This study evaluates CNN's performance and determines the feasibility of 24-h recordings. Seven sensors provided accelerometer and gyroscope data from 14 typically developed adults during videotaped physical activity. The performance of the CNN was assessed against test data and human video annotation. For feasibility testing, one typically developed adult and one adult with CP wore sensors for 24 h. The CNN demonstrated exceptional performance against test data, with a mean accuracy of 99.7%. Its general true positives (TP) and true negatives (TN) were 1.00. Against human annotators, performance was high, with mean accuracy at 83.4%, TP 0.84, and TN 0.83. Twenty-four-hour recordings were successful without data loss or adverse events. Participants wore sensors for the full wear time, and the data output were credible. We conclude that monitoring real-world movement behavior in individuals with CP is possible with multiple wearable sensors and CNN. This is of great value for identifying functional decline and informing new interventions, leading to improved outcomes.

Treatment of Chronic Degenerative Hip Pain in a Male Patient With Cerebral Palsy Four Decades After Reverse Osteotomy

Patients with cerebral palsy (CP) frequently require surgical hip interventions in early adulthood due to spasticity-related gait abnormalities. In most instances, these cases are characterized by severe restrictions on mobility. This is the case of a male patient with CP who underwent right proximal femoral open reduction internal fixation (ORIF) and reverse osteotomy for right hip subluxation in young adulthood. Patients with CP who undergo total hip arthroplasty (THA) or ORIF with reverse osteotomy often require future revision. The patient was initially given an estimated 10-year longevity for his plate and screw construct (hardware). Forty-four years later, the patient presented with debilitating chronic bilateral hip pain, requiring the assistance of a cane for ambulation. There is a limited body of knowledge on ORIF and reverse osteotomy follow-up in patients with CP within a 30- to 50-year period. At the 44th-year follow-up, CT and X-ray imaging found postoperative changes in the right femur, including intact hardware, bilateral acetabular dysplasia, right femoral stress fracture, progression of hip arthritis, and right iliopsoas bursitis. Surgery for hardware revision was not indicated. Gradual restoration of function was achieved over a 14-month period with conservative management. This case suggests that physical therapy (PT), exercise, and sporadic non-steroidal anti-inflammatory drug (NSAID) use are effective for improving chronic degenerative changes, associated bursitis, and loss of function in patients who developed CP-induced gait complications in young adulthood. These improvements can be made several decades after undergoing ORIF and osteotomies. This course of treatment was effective in improving the patient's quality of life without additional surgical interventions.

Risk factors and outcome of epilepsy in adults with cerebral palsy or intellectual disability

INTRODUCTION

Epilepsy is found in 10-60% of individuals with cerebral palsy (CP) and 5.5-35% with intellectual disability (ID). However, little is known about the long-term evolution of epilepsy among adults. The aim of the study is to describe the factors associated with epilepsy and its outcome in a population of adults with CP or ID.

METHODS

This retrospective study reviewed the medical records of 306 individuals with CP/ID. All individuals underwent neurological, psychiatric, and neuropsychological follow-ups.

RESULTS

In the cohort, 72.5% of the individuals had a CP diagnosis, with a mean age of 36.4 years (IQR 24.0-46.0). Epilepsy was present in 55.6% of the individuals and was associated with CP (p < 0.01), spastic subtype (p < 0.01), a higher degree of ID (p < 0.01), hemorrhagic and congenital malformation etiologies (p 0.011), abnormal neuroimaging (p < 0.01), and worse scores on motor and communication scales (p < 0.01). Drug-resistant epilepsy (DRE) (22.4%) was associated with higher scores on motor scales (p < 0.01). Additionally, 42.3% of the individuals who attempted antiseizure medication (ASM) withdrawal experienced recurrence, which was associated with epileptic activity on the electroencephalogram (EEG) (p 0.004).

CONCLUSIONS

Epilepsy is a common comorbidity in adults with CP or ID and is associated with greater brain damage and a more severe phenotype. Seizure recurrence after ASM withdrawal occurred in half of the individuals and was associated with epileptic activity on the EEG.

Adults with Cerebral Palsy: Navigating the Complexities of Aging

The goal of this narrative review is to highlight the healthcare challenges faced by adults with cerebral palsy, including the management of long-term motor deficits, difficulty finding clinicians with expertise in these long-term impairments, and scarcity of rehabilitation options. Additionally, this narrative review seeks to examine potential methods for maintaining functional independence, promoting social integration, and community participation. Although the brain lesion that causes the movement disorder is non-progressive, the neurodevelopmental disorder worsens from secondary complications of existing sensory, motor, and cognitive impairments. Therefore, maintaining the continuum of care across one's lifespan is of utmost importance. Advancements in healthcare services over the past decade have resulted in lower mortality rates and increased the average life expectancy of people with cerebral palsy. However, once they transition from adolescence to adulthood, limited federal and community resources, and health care professionals' lack of expertise present significant obstacles to achieving quality healthcare and long-term benefits. This paper highlights the common impairments seen in adults with cerebral palsy. Additionally, it underscores the critical role of long-term healthcare and management to prevent functional decline and enhance quality of life across physical, cognitive, and social domains.

Motor deficits are associated with increased glial cell activation in the hypothalamus and cerebellum of young rats subjected to cerebral palsy

Cerebral palsy (CP) is a syndrome characterized by a wide range of sensory and motor damage, associated with behavioral and cognitive deficits. The aim of the present study was to investigate the potential of a model of CP using a combination of perinatal anoxia and sensorimotor restriction of hind paws to replicate motor, behavioral and neural deficits. A total of 30 of male Wistar rats were divided into Control (C, n = 15), and CP (CP, n = 15) groups. The potential of the CP model was assessed by evaluating food intake, the behavioral satiety sequence, performance on the CatWalk and parallel bars, muscle strength, and locomotor activity. The weight of the encephalon, soleus, and extensor digitorum longus (EDL) muscles, and the activation of glial cells (microglia and astrocytes) were also measured. The CP animals showed delayed satiety, impaired locomotion on the CatWalk and open field test, reduced muscle strength, and reduced motor coordination. CP also reduced the weight of the soleus and muscles, brain weight, liver weight, and quantity of fat in various parts of the body. There was also found to be an increase in astrocyte and microglia activation in the cerebellum and hypothalamus (arcuate nucleus, ARC) of animals subjected to CP.

Tools for Nutrition Assessment of Adults with Cerebral Palsy: Development of a Gold Standard

PURPOSE OF REVIEW

Cerebral palsy (CP) is a group of disorders caused by non-stabilized cerebral lesions. Individuals with this disorder are at a higher risk of suffering from malnutrition and other related detrimental effects to their quality of life. For this reason, accurate methods of nutritional assessment are vital for people suffering from this condition. While assessment of nutritional status in children with CP has been extensively studied, very few studies have been carried out on adults. These limitations are due to the great anatomical-functional variability characteristic of this syndrome. Difficulties that derive from this variability in adult patients with CP mean that there remains an urgent need for certain standards of nutritional assessment for this population. The objective of this review is to compile the latest trends in nutritional assessment in adults with CP to guide the development of a conceptual framework for future research.

RECENT FINDINGS

With this aim, relevant studies have been identified. The most commonly used technique to evaluate nutritional status is the BMI because of its ease-of-use. However, its well-known limitations fail to adequately estimate the nutritional status in this population, with measurements of patients with CP yielding results that are much less accurate than those that already exist in the general population. Although more studies are needed, kinanthropometry is considered one of the most reliable techniques; nevertheless, the anatomical limitation characteristic of CP plays a limiting factor.

Longitudinal Patterns of Postfracture Outpatient Physical Therapy and Occupational Therapy Use and Its Association With 3-Year Mortality Among Adults With Cerebral Palsy

OBJECTIVE

Fragility fractures are common among adults with cerebral palsy (CP), but clinical rehabilitation use after fracture and its effect on long-term health outcomes have not been sufficiently studied. The objectives of this study were to identify patterns of the use of physical therapy, occupational therapy, or both in the 6-month postfracture period and the association with 3-year mortality in adults with CP.

METHODS

This retrospective cohort study included adults who were ≥18 years old, had CP, and had sustained an incident fragility fracture between January 1, 2014, and December 31, 2016, as identified from a random 20% Medicare fee-for-service dataset. Six-month outpatient physical therapy or occupational therapy use patterns after fracture were identified using group-based trajectory modeling. Cox regression determined the association between physical therapy or occupational therapy use trajectory patterns and mortality from 6 months to 3 years after fracture, adjusting for confounders. Effect modification by key characteristics was tested, including age, sex, and the modified Whitney Comorbidity Index (mWCI), which is a CP-specific comorbidity index that better captures overall medical complexity.

RESULTS

Of the 2429 participants included, the majority (73.2%) were characterized as having little to no probability of physical therapy or occupational therapy use, whereas 16.0 and 10.7% were characterized as having early initiation and later initiation, respectively. Compared to the mortality rate for the little to no physical therapy or occupational therapy group, the mortality rates were 26% lower for the early physical therapy or occupational therapy initiation group (hazard ratio [HR] = 0.74; 95% CI = 0.55-1.00) and were 20% lower for the later initiation group (HR = 0.80; 95% CI = 0.57-1.12). There was effect modification by the mWCI. The mortality rate was lower when the early initiation and later initiation groups were compared to the little to no initiation group across all mWCI values examined (median and interquartile range), but the effect was stronger (ie, lower mortality rate) for lower mWCI values for both early initiation and later initiation groups.

CONCLUSION

Most adults with CP underutilize outpatient physical therapy or occupational therapy services within 6 months postfracture. Early or later initiation versus little to no physical therapy or occupational therapy use was associated with a lower HR of mortality, although the effect was stronger and statistically significant among those with less medical complexity.

IMPACT

Throughout their lives, the use of rehabilitation services in individuals with CP, including physical therapy and occupational therapy, dramatically declines despite the need for continued rehabilitation across their lifespans. This study characterized longitudinal physical therapy or occupational therapy use patterns in the 6 months following a fragility fracture among adults with CP and found that nearly 3 in 4 adults with CP had little to no physical therapy or occupational therapy use during this critical window to optimize postfracture health and function. Further, those who more regularly used physical therapy or occupational therapy services, regardless of the timing of initiation (early vs later), had significantly improved survival up to 3 years after fracture, suggesting the need for greater access to and delivery of clinical rehabilitation services.

Impairments and comorbidities in adults with cerebral palsy and spina bifida: a meta-analysis

Introduction

Aging with a childhood-onset disability, such as cerebral palsy (CP), spina bifida (SB), and muscular diseases (MD), comes along with significant impairments and comorbidities. Despite the increasing evidence an overall picture is lacking. This study aimed to review the literature about adults with CP/SB/MD and impairments and comorbidities to perform a meta-analysis.

Materials and methods

Embase, PubMed, Cinahl, and Google Scholar were searched (2000-2020). Search terms included adults with one of the aforementioned disabilities combined with impairments and comorbidities. If specific impairments or comorbidities were reported by at least four studies, these were included in the study. Pooled prevalence (95% Confidence Interval) of impairments/comorbidities were calculated.

Results

The search yielded 7,054 studies of which 95 were included in the meta-analysis (64 CP, 31 SB, 0 MD). In total estimates were calculated for 26 (CP) and 11 (SB) outcomes. In adults with CP, pain [56.4% (95%CI 48.8-63.8)], deformities [44.2% (95%CI 12.9-78.4)], intellectual disability [37.2% (95%CI 26.7-48.3)], and fatigue [36.9% (95%CI 24.6-50.1)] were most prevalent; renal disease [3.0% (95%CI 2.1-4.2)] and stroke/rheumatic diseases {4.8% (95%CI 3.4-6.5; 4.8% (95%CI 1.5-9.9)] respectively} were least prevalent. For adults with SB, bladder incontinence [60.0% (95%CI 50.5-69.2)], bowel incontinence [49.2% (95%CI 34.5-64.0)], pain [44.1% (95%CI 27.4-61.5)], and sleeping problems [30.3% (95%CI 4.7-65.8)] were most prevalent; diabetes [4.8% (95%CI 2.8-7.3)] and renal disease [8.7% (95%CI 2.0-19.9)] were least prevalent. The included studies showed large heterogeneity.

Conclusions

More research is needed to study health issues in adults with MD. Adults with CP or SB deal with a variety of health issues. More attention for the mental health of these adults is needed. There also is a need for accessible and adequate screening, preventive measures and clinical follow-up.

The perception of disability in cerebral palsy: a cross-sectional study using the WHODAS 2.0

This observational study aims to describe the level of perceived disability in Cerebral Palsy (CP). We described the perception of adults by using the interviewer-administered version of the WHO disability assessment schedule (WHODAS 2.0). In case of intellectual disability (ID), the proxy-administered version was used, and a caregiver was asked to report the difficulties experienced by the patient; 199 patients were enrolled. The level of perceived disability was higher when referred to patients with ID (proxy report) than when referred to patients without ID (p < .001). For all patients, the level of perceived disability varied depending on the severity and the localization of motor impairment (both p < .001). No differences were observed based on the type of motor impairment. The perceived disability was correlated with age only for patients with no ID (p < .05). The WHODAS 2.0 may be a useful tool to explore the perception of disability in CP.

Lifelong Fitness in Ambulatory Children and Adolescents with Cerebral Palsy II: Influencing the Trajectory

Physical activity of at least moderate intensity in all children contributes to higher levels of physical and psychological health. While essential, children with cerebral palsy (CP) often lack the physical capacity, resources, and knowledge to engage in physical activity at a sufficient intensity to optimize health and well-being. Low levels of physical activity place them at risk for declining fitness and health, contributing to a sedentary lifestyle. From this perspective, we describe a framework to foster a lifelong trajectory of fitness in ambulatory children with CP (GMFCS I-III) as they progress into adolescence and adulthood, implemented in conjunction with a training program to augment bone and muscle health. First, we recommend that altering the fitness trajectory of children with CP will require the use of methods to drive behavioral change prior to adolescence. Second, to promote behavior change, we suggest embedding lifestyle intervention into fitness programming while including meaningful activities and peer socialization to foster self-directed habit formation. If the inclusion of lifestyle intervention to drive behavior change is embedded into fitness programs and found to be effective, it may guide the delivery of targeted programming and community implementation. Participation in comprehensive programming could alter the long-term trajectory of musculoskeletal health while fostering strong self-efficacy in persons with CP.

Continuity of Care in Adults Aging with Cerebral Palsy and Spina Bifida: The Importance of Community Healthcare and Socioeconomic Context

Continuity of care is considered a key metric of quality healthcare. Yet, continuity of care in adults aging with congenital disability and the factors that contribute to care continuity are largely unknown. Using data from a national private administrative health claims database in the United States (2007-2018). we examined continuity of care in 8596 adults (mean age 48.6 years) with cerebral palsy or spina bifida. Logistic regression models analyzed how proximity to health care facilities, availability of care providers, and community socioeconomic context were associated with more continuous care. We found that adults aging with cerebral palsy or spina bifida saw a variety of different physician specialty types and generally had discontinuous care. Individuals who lived in areas with more hospitals and residential care facilities received more continuous care than those with limited access to these resources. Residence in more affluent areas was associated with receiving more fragmented care. Findings suggest that over and above individual factors, community healthcare resources and socioeconomic context serve as important factors to consider in understanding continuity of care patterns in adults aging with cerebral palsy or spina bifida.

Health care transition for cerebral palsy with intellectual disabilities: A systematic review

OBJECTIVE

Today, most individuals with cerebral palsy are adults who need a paediatric-to-adult health care transition. However, many remain in paediatric care for treatment of adult-onset health issues. Therefore, a systematic review based on the 'Triple Aim' framework was performed to determine the status of paediatric-to-adult health care transition for people with cerebral palsy. A comprehensive evaluation of transitional care was proposed for using this framework. It consists of 'experience of care', meaning satisfaction with the care, 'population health', meaning the well-being of patients, and 'cost', meaning cost-effectiveness.

METHOD

Electronic database (PubMed) searches were performed. The inclusion criteria were original articles published between 1990 and 2020. The search terms used in this study were ('cerebral palsy' AND 'transition to adult health care') OR ('cerebral palsy' AND 'transition'). The study type had to be epidemiological, case report, case-control, and cross-sectional, but not qualitative. The outcomes of the studies were categorised into 'care experience', 'population health', and 'cost', according to the Triple Aim framework.

RESULTS

Thirteen articles met the abovementioned inclusion criteria. Few studies have examined the effect of the intervention of transition for young adults with cerebral palsy. Participants in some studies had no intellectual disability. Young adults were dissatisfied with the 'care experience', 'population health', and 'cost' and had unmet health needs and inadequate social participation.

INTERPRETATION

Further transition intervention studies with a comprehensive assessment and proactive involvement of individuals are warranted. The presence of an intellectual disability should be considered.

Prevalence and incidence of chronic conditions among adults with cerebral palsy: A systematic review and meta-analysis

AIM

To assess the prevalence and incidence of chronic conditions among adults with cerebral palsy (CP) and compare them to the prevalence and incidence among adults without CP.

METHOD

We searched MEDLINE and Embase for studies reporting the prevalence or incidence of one or more chronic conditions among adults with CP. Two independent reviewers screened titles, abstracts, and full-text articles. Two independent reviewers extracted data relating to prevalence and incidence and appraised study quality. We performed random-effects meta-analyses to pool prevalence and incidence.

RESULTS

We identified 69 studies; 65 reported the prevalence of 53 conditions and 13 reported the incidence of 21 conditions. At least 20% of adults had the following conditions: depression (21%); anxiety (21%); mood affective disorders (23%); asthma (24%); hypertension (26%); epilepsy (28%); urinary incontinence (32%); malnutrition (38%); and scoliosis (46%). Adults with CP were more likely to have type 2 diabetes, anxiety, bipolar disorder, depression, schizophrenia, hypertension, ischaemic heart disease, stroke, cerebrovascular disease, asthma, liver disease, osteoarthritis, osteoporosis, underweight, and chronic kidney disease than adults without CP.

INTERPRETATION

These data from 18 countries, which provide an international perspective, may be used to promote awareness, identify targets for intervention, and inform the development of appropriate supports for adults with CP.

Post-fracture rehabilitation pathways and association with mortality among adults with cerebral palsy

OBJECTIVE

Rehabilitation may mitigate the high mortality rates and health declines post-fracture for adults with cerebral palsy, but this is understudied. The objectives were to characterize the post-fracture rehabilitation pathways and identify their association with 1-year survival among adults with cerebral palsy.

METHODS

A retrospective cohort study of adults with cerebral palsy with a fragility fracture with continuous health plan enrollment ≥1-year prior to and ≥1 day after their fracture date was performed using a random 20% Medicare fee-for-service dataset. Participants were categorized as a home discharge or inpatient rehabilitation admission post-fracture. For the home discharge cohort, weekly exposure to outpatient physical/occupational therapy (PT/OT) was examined up to 6-month post-fracture. Cox regression examined the association between time-varying PT/OTuse within 6-month post-fracture and mortality from 30 days to 1-year post-fracture before and after adjusting for confounders (e.g. medical complexity).

RESULTS

Of 3598 adults with cerebral palsy with an incident fragility fracture, 74% were discharged home without inpatient rehabilitation; they were younger, but more medically complex compared to the 26% admitted to inpatient rehabilitation. Among the home discharge cohort (n = 2662), 43.1% initiated PT/OTwithin 6-month post-fracture, and cumulative PT/OTexposure post-fracture was associated with improved survival; for example, per 3 weeks of PT/OTexposure, the adjusted mortality rate was 40% lower (95% confidence interval (CI) = 0.41-0.89).

CONCLUSIONS

Most adults with cerebral palsy with a fragility fracture were discharged home rather than to inpatient rehabilitation, and only 43.1% of that group initiated outpatient PT/OTwithin 6 months post-fracture. Receiving outpatient PT/OTwas associated with improved 1-year survival.

Multimorbidities and quality of life in adult cerebral palsy over 40 years

AIM

This study aimed to describe the most common combinations of comorbidities and their relationship to quality of life in a sample of adults over 40 years of age with cerebral palsy.

METHODS

Patients who are 40 years or older and admitted to the hospital in the last 5 years and were diagnosed with cerebral palsy were included. Demographic data and comorbidities were both questioned through the Patient Information Management System and confirmed by asking the individual about their diseases. The patients' quality of life was evaluated with the EQ-5D-3L Telephone interview version. Principal component analysis was used to determine comorbidity combinations for multiple morbidity.

RESULTS

Comorbidity was found in 72.1% of the participants and multimorbidity was found in 47.5%. The 5 most common comorbidities were musculoskeletal diseases (34.4%), psychiatric diseases (21.3%), essential hypertension (21.3%), osteoporosis (18%) and hyperlipidemia (18%). As a result of principal component analysis, a total of five components are formed and this most common comorbidity combinations in the sample explained 66.78% of the total variance.

CONCLUSIONS

New combinations of comorbidities have been demonstrated that may perhaps serve as a starting point for identifying new association of pathways. Future efforts are needed to identify modifiable factors for early intervention and prevention of chronic health problems in this population.

Infectious Complications and Operative Management of Intrathecal Baclofen Pumps in the Pediatric Population: A Systematic Review and Meta-Analysis of 20 Years of Pooled Experience

BACKGROUND

Intrathecal baclofen (ITB) is a treatment modality used to improve the quality of life of patients with intractable spasticity and dystonia. Although it is an effective solution in patients failing oral interventions, it is associated with potential infectious complications. It is known that pediatric patients with ITB have significantly higher infection rates compared with adult patients. The cause of these higher rates in pediatric patients remains unclear. In the present study, we performed a meta-analysis focusing on the incidence of infection, and clarification of potential risk factors for infection in pediatric patients with ITB.

METHODS

This meta-analysis was performed in accordance with the PRISMA guidelines. An electronic database search was performed through PubMed, Web of Science, Embase, and Cochrane Library databases. Eligibility criteria and bias assessment were applied before statistical analysis.

RESULTS

The 17 studies identified yielded 2238 pediatric patients treated with implanted ITB pumps between 1994 and 2014. Infection comprised 34% of observed complications, second only to catheter malfunction. Pediatric ITB primary infection ranged between 0% and 44% among included studies (interquartile range, 4.85%-18.85%). A linear mixed-effects regression model showed that subfascial implantation had 12% lower primary infection rates compared with subcutaneous implantations across the literature. The relative risk of infection was 56% lower in pediatric patients with subfascially implanted ITB pumps.

CONCLUSIONS

Surgeons and clinicians should use these data to better assess patient risk-benefit when considering ITB pump implantation.

A core outcome set for multimorbidity risk in individuals with cerebral palsy

AIM

To: (1) investigate the importance of outcome measurement instruments (OMIs) within a core outcome set (COS) for multimorbidity (at least two chronic health conditions) risk in individuals with cerebral palsy (CP); (2) investigate the feasibility of OMIs within the COS in international clinical research settings in adolescents and adults with CP; and (3) describe the associations between the COS data and Gross Motor Function Classification System (GMFCS) levels.

METHOD

Eighty-three individuals with CP completed a survey on health outcomes: physical behaviour, nutrition, sleep, endurance, body composition, blood pressure, blood lipids, and glucose. A cross-sectional study assessed the feasibility of the COS in 67 adolescents and adults with CP (mean age 30y, SD 15y 1mo, min-max: 14-68y, 52.2% male) at four centres. Prevalence of multimorbidity risk and associations with GMFCS levels are described.

RESULTS

Most participants rated physical behaviour, nutrition, sleep, and endurance as very important. Body composition, blood pressure, nutrition, and sleep were highly feasible since data were collected in 88% or more participants who consented to having the assessments. Physical behaviour, cardiorespiratory endurance, and blood draws were collected in less than 60% of participants. Total time sedentary (ρ=0.53, p<0.01) and endurance (ρ=-0.46, p<0.01) were significantly associated with GMFCS level.

INTERPRETATION

The COS identified that most participants had poor sleep quality and endurance, did not have healthy diets, and showed increased sedentary behaviour. Individuals with CP valued these outcomes as most important, suggesting a need to assess these modifiable behaviours in this population. Objective measures of physical behaviour and cardiorespiratory endurance in the COS required additional personnel, time, and participant burden. We recommend that healthcare providers should perform a simpler first screen using questionnaire-based assessments and then focus the use of the remainder of the COS if required for the patient.

Post-fracture pneumonia risk and association with health and survival outcomes for adults with cerebral palsy: A retrospective cohort study

BACKGROUND

For adults with cerebral palsy (CP), fragility fractures may be a risk factor for pneumonia, a leading cause of death for this population; yet, the timing and complications are unknown. The objectives were to determine the 30-day pneumonia rate post-fracture and its association with mortality and incident cardiovascular events among adults with CP.

METHODS

This retrospective cohort study used nationwide administrative claims data from 01/01/2012-12/31/2017 from a random 20% sample of the Medicare fee-for-service and Optum Clinformatics® Data Mart. Cohorts included ≥18 years of age with CP with an incident fragility fracture (CP + Fx) and comparison cohorts: CP without fractures (CPw/oFx) and without CP with an incident fragility fracture (w/oCP + Fx). Incidence rate (IR) of pneumonia 30-days post-fracture and IR ratios were estimated by age group: 18-40, 41-64, and ≥ 65 years. For CP + Fx, Cox regression examined the association between time-varying pneumonia (within 30-days post-fracture) with mortality and incidence of cardiovascular events 0-30-days and 31-365-days post-fracture.

RESULTS

There were 3688 CP + Fx (mean [SD] age, 58.2 [14.9]; 56.4% women), 29,429 CPw/oFx (50.3 [15.8]; 45.9% women), and 363,995 w/oCP + Fx (65.9 [18.3]; 65.5% women). The IR of 30-day pneumonia for CP + Fx was similar across age groups (IR per 100 person-months, 8.4-11.0) and 1.77-16.18-fold higher (all P < 0.05) than comparison cohorts. Peri/post-fracture pneumonia was associated with an increased rate of mortality (30-day-adjusted HR [aHR] = 5.89, 95%CI = 3.54-9.81; 31-365-day aHR = 2.89, 95%CI = 2.13-3.92), congestive heart failure 0-30-days (aHR = 3.64, 95%CI = 2.01-6.57) and 31-365-days (time-dependent), myocardial infarction 31-365-days (aHR = 2.03, 95%CI = 1.11-3.71), and cerebrovascular disease 0-30-days (time-dependent), without evidence of effect modification by age, sex, or fracture site.

CONCLUSIONS

Adults with CP are particularly vulnerable to 30-day risk of post-fracture pneumonia and its complications across the adult lifespan and not just in the elderly years.

Secondary Osteoporosis

Osteoporosis is a global public health problem, with fractures contributing to significant morbidity and mortality. Although postmenopausal osteoporosis is most common, up to 30% of postmenopausal women, > 50% of premenopausal women, and between 50% and 80% of men have secondary osteoporosis. Exclusion of secondary causes is important, as treatment of such patients often commences by treating the underlying condition. These are varied but often neglected, ranging from endocrine to chronic inflammatory and genetic conditions. General screening is recommended for all patients with osteoporosis, with advanced investigations reserved for premenopausal women and men aged < 50 years, for older patients in whom classical risk factors for osteoporosis are absent, and for all patients with the lowest bone mass (Z-score ≤ -2). The response of secondary osteoporosis to conventional anti-osteoporosis therapy may be inadequate if the underlying condition is unrecognized and untreated. Bone densitometry, using dual-energy x-ray absorptiometry, may underestimate fracture risk in some chronic diseases, including glucocorticoid-induced osteoporosis, type 2 diabetes, and obesity, and may overestimate fracture risk in others (eg, Turner syndrome). FRAX and trabecular bone score may provide additional information regarding fracture risk in secondary osteoporosis, but their use is limited to adults aged ≥ 40 years and ≥ 50 years, respectively. In addition, FRAX requires adjustment in some chronic conditions, such as glucocorticoid use, type 2 diabetes, and HIV. In most conditions, evidence for antiresorptive or anabolic therapy is limited to increases in bone mass. Current osteoporosis management guidelines also neglect secondary osteoporosis and these existing evidence gaps are discussed.

ASSOCIATION BETWEEN DAILY PHYSICAL ACTIVITY AND CLINICAL ANTHROPOMORPHIC MEASURES IN ADULTS WITH CEREBRAL PALSY

OBJECTIVE

To describe the relationship between activity level and cardiovascular risk measures as well as describe general activity patterns of adults with cerebral palsy Design: Cross-Sectional Setting: Academic Outpatient Rehabilitation Clinic.

PARTICIPANTS

47 adults with cerebral palsy (CP) Interventions: Not applicable Main Outcome Measures: Gross Motor Functional Classification System (GMFCS) level was determined by validated self-report questionnaire. Activity (daily step count, walk time, sitting time, standing time, and transitional movements) over 6 days recorded using an activPAL. Weight, body mass index (BMI), and waist to hip ratio (WHR) were measured. Bivariate relationships between anthropomorphic and activity measures were assessed.

RESULTS

38 participants completed all measurements. Nine were excluded due to incomplete activPAL data. The median age was 28.50 years [interquartile range 24.25,47.00], range 18-77 years. Participants' GMFCS levels were I:13%, II:16%, III:21%, IV:34%, and V:16%. Median steps/day for GMFCS I/II participants were 5258.3[3606.8, 6634.7], while median steps/day were 1681.3 [657.2, 2751.8] and 30.0 [6.8, 54.2] for GMFCS level III and IV/V participants, respectively. Significantly greater steps/day were found for GMFCS I/II or III participants compared to those GMFCS IV/V (p<0.001 and p=0.0074, respectively). 60.5% of the subjects had a BMI in the normal range, 10.5% were obese, 23.6% were overweight, and 5.3% were underweight. For subjects with GMFCS I/II, the Spearman's rank correlation coefficient for time standing and waist circumference was -0.73 (0.01). Subjects GMFCS III and GMFCS IV/V had respective correlations of -0.16 (0.71) and -0.01 (0.98). For subjects with GMFCS I/II, the Spearman's rank correlation coefficient for standing time and BMI was -0.55 (p= 0.08). For the GMFCS III and GMFCS IV/V groups the respective correlation was -0.19 (0.67) and 0.00 (1.00).

CONCLUSIONS

Subjects with GMFCS level I or II who engaged in more activity tended to have more favorable anthropometric profiles. Subjects GMFCS III, IV, or V did not have a similar trend. Our findings suggest factors beyond activity patterns affect anthropometrics to a greater degree in those with higher GMFCS levels.

Rhythm and Reaching: The Influence of Rhythmic Auditory Cueing in a Goal-Directed Reaching Task With Adults Diagnosed With Cerebral Palsy

Improvements in functional reaching directly support improvements in independence. The addition of auditory inputs (e.g., music, rhythmic counting) may improve goal-directed reaching for individuals with cerebral palsy (CP). To effectively integrate auditory stimuli into adapted teaching and rehabilitation protocols, it is necessary to understand how auditory stimuli may enhance limb control. This study considered the influence of auditory stimuli during the planning or execution phases of goal-directed reaches. Adults (with CP = 10, without CP = 10) reached from a home switch to two targets. Three conditions were presented-no sound, sound before, and sound during-and three-dimensional movement trajectories were recorded. Reaction times were shorter for both groups in the sound before condition, while the group with CP also reached peak velocity relatively earlier in the sound before condition. The group with CP executed more consistent movements in both sound conditions. Sound presented before movement initiation improved both the planning and execution of reaching movements for adults with CP.

Association of Obesity on Outcomes of Hospitalized Patients with Cerebral Palsy

OBJECTIVE

Among hospitalized adults with cerebral palsy (CP), it is unknown whether obesity is associated with clinical and resource utilization outcomes. We sought to identify the association of obesity on clinical and resource utilization outcomes in this population.

METHODS

This retrospective cohort study analyzed years 2016 and 2017 of the Nationwide Inpatient Sample database and examined hospitalized adults with CP. Regression analyses were used to evaluate mortality and resource utilization.

RESULTS

In total, 154,219 adults with CP were hospitalized. Among them, 13,475 (8.7%) had a secondary diagnosis for obesity. Patients with obesity were older (mean age ± standard error of the mean: 49.9 ± 0.18 versus 44.7 ± 0.18 years, P < 0.01), a greater proportion were female (60.7% vs 43.2%, P < 0.01), and were more likely to be insured by Medicare (65.2% vs 56.2%, P < 0.01). Patients with obesity had higher comorbidity burdens (Charlson comorbidity score ≥ 3: 22.3% vs 9.8%, P < 0.01). Those with obesity had lower mortality rates (1.6% vs 2.4%; P < 0.01). After adjustment for confounders, mortality for patients with obesity remained lower (adjusted odds ratio 0.5, 95% confidence interval [CI] 0.4-0.7, P < 0.01). Hospital charges (adjusted mean difference $2499, 95% CI $6202-$1202, P = 0.18) and length of stay (adjusted mean difference 0.01 days; 95% CI -0.28 to 0.31, P = 0.93) were not significantly different between the groups.

CONCLUSIONS

Obesity was associated with reduced mortality among adult patients in the hospital who had CP. This finding is consistent with the obesity paradox that has been observed repeatedly in patients with other chronic diseases. Further studies investigating hospitalized patients with CP are needed to corroborate these findings.

Shared Physiologic Pathways Among Comorbidities for Adults With Cerebral Palsy

Objective: Aging with cerebral palsy is accompanied by a declining health and function status across neurological and non-neurological systems. There is a need to understand the shared pathophysiology among comorbidities for adults with cerebral palsy, to inform clinical assessment and guidelines for interventions to improve healthful aging. To begin defining multimorbidity, this study identified the most common comorbidity combinations and their association with mortality among a representative sample of adults with cerebral palsy.

Methods: Data from 2016 to 2018 were used from a random 20% sample from the fee-for-service Medicare database. Adults ≥18 years with cerebral palsy and 25 neurological and non-neurological comorbidities were obtained from 2016. Principal component (PC) analysis identified the most common comorbidity combinations, defined as individual PCs. Cox regression estimated the hazard ratio (HR) of 2-year mortality including all PCs and demographics in a single model. To facilitate comparisons, PC scores were transformed into quintiles (reference: lowest quintile).

Results: Among the 16,728 adults with cerebral palsy, the most common comorbidity combinations (PCs) in order were: cardiorespiratory diseases, dysphagia, and fluid/electrolyte disorders; metabolic disorders (e.g., diabetes, renal disease, hypertension); neurologic-related disorders (e.g., dementia, cerebrovascular disease); gastrointestinal issues; and orthopedic-related disorders. During the 2-year follow-up, 1,486 (8.9%) died. In the adjusted model, most PCs were associated with an elevated mortality rate, especially the first PC (5th quintile HR = 3.91; 95%CI = 3.29–4.65).

Discussion: This study identified the most common comorbidity combinations for adults with cerebral palsy, many of them were deadly, which may inform on the underlying pathophysiology or shared characteristics of multimorbidity for this population.

Psychological, Cardiometabolic, and Musculoskeletal Morbidity and Multimorbidity Among Adults With Cerebral Palsy and Spina Bifida: A Retrospective Cross-sectional Study

BACKGROUND

Individuals living with cerebral palsy or spina bifida are at heightened risk for a number of chronic health conditions, such as secondary comorbidities, that may develop or be influenced by the disability, the presence of impairment, and/or the process of aging. However, very little is known about the prevalence and/or risk of developing secondary comorbidities among individuals living with cerebral palsy or spina bifida throughout adulthood. The objective of this study was to compare the prevalence of psychological, cardiometabolic, and musculoskeletal morbidity and multimorbidity among adults with and without cerebral palsy or spina bifida.

METHODS

Privately insured beneficiaries were included if they had an International Classification of Diseases, Ninth Revision, Clinical Modification diagnostic code for cerebral palsy or spina bifida (n = 29,841). Adults without cerebral palsy or spina bifida were also included (n = 5,384,849). Prevalence estimates of common psychological, cardiometabolic, and musculoskeletal morbidity and multimorbidity (≥2 conditions) were compared.

RESULTS

Adults living with cerebral palsy or spina bifida had a higher prevalence of all psychological disorders and psychological multimorbidity (14.6% vs. 5.4%), all cardiometabolic disorders and cardiometabolic multimorbidity (22.4% vs. 15.0%), and all musculoskeletal disorders and musculoskeletal multimorbidity (12.2% vs. 5.4%), as compared with adults without cerebral palsy or spina bifida, and differences were to a clinically meaningful extent.

CONCLUSIONS

Adults with cerebral palsy or spina bifida have a significantly higher prevalence of common psychological, cardiometabolic, and musculoskeletal morbidity and multimorbidity, as compared with adults without cerebral palsy or spina bifida. Efforts are needed to facilitate the development of improved clinical screening algorithms and early interventions to reduce risk of disease onset/progression in these higher risk populations.

Pain phenotypes among adults living with cerebral palsy and spina bifida

ABSTRACT

Chronic pain is the most commonly reported physical symptomology of cerebral palsy (CP) and spina bifida (SB) throughout the lifespan, and yet, pain is perhaps the least understood comorbidity in these populations. The objective of this study was to compare the prevalence and types of pain diagnosed among adults living with and without CP or SB. In this retrospective cohort study, we analyzed data from a nationwide commercial insurance claims database. Beneficiaries were included if they had an International Classification of Diseases, Ninth revision, Clinical Modification diagnosis code for CP or SB (n = 22,648). Adults without CP or SB were also included as controls (n = 931,623). Pain phenotypes (nociceptive, nociplastic, and neuropathic pain) and pain multimorbidity (≥2 conditions) were compared. We found that adults living with CP or SB had a higher prevalence of any pain disorders (55.9% vs 35.2%), nociceptive pain (44.0% vs 26.7%), nociplastic pain (26.1% vs 11.9%), neuropathic pain (9.6% vs 5.6%), and pain multimorbidity (21.1% vs 8.4%), as compared to adults without CP or SB, and differences were to a clinically meaningful extent. Adjusted odds ratios of nociceptive pain (odds ratio [OR]: 2.20; 95% confidence interval [CI]: 2.15-2.24), nociplastic pain (OR: 2.47; 95% CI: 2.41-2.53), neuropathic pain (OR: 2.71; 95% CI: 2.54-2.89), and other pain (OR: 3.92; 95% CI: 3.67-4.19) were significantly higher for adults living with CP or SB. In conclusion, adults with CP or SB have a significantly higher prevalence and odds of common peripheral, central, and neuropathic pain disorders and pain multimorbidity, as compared to adults without CP or SB.

The Association Between Kidney Disease and Mortality Among Adults With Cerebral Palsy-A Cohort Study: It Is Time to Start Talking About Kidney Health

Objective: Recent evidence shows that adults with cerebral palsy (CP) have an increased risk for kidney disease, but nothing is known about how kidney disease integrates with their overall health. To begin understanding the importance of kidney health, the objective was to determine if kidney disease is associated with mortality among adults with CP after accounting for comorbidities common to CP and kidney disease.

Methods: Data from 2016 to 2018 from adults ≥18 years with CP were used from a random 20% sample fee-for-service Medicare database. Kidney disease in 2016 was ascertained as chronic kidney disease (CKD) stages 1–4, end stage kidney disease (ESKD), nephritic and nephrotic syndrome, and renal osteodystrophy. A modified version of the Whitney Comorbidity Index (modWCI) was used, which includes 24 comorbidities relevant to CP and kidney disease. Mortality rate ratio (MRR) through the year 2018 was estimated for each kidney disease and Cox regression estimated the hazard ratio (HR) of mortality after adjusting for demographics, co-occurring neurological conditions, and the modWCI.

Results: Prevalence of kidney disease was 7.3% among 16,728 adults with CP. MRR was elevated for any kidney disease (MRR = 3.14; 95%CI = 2.76–3.58) and most subtypes (MRR = 2.21–3.56; all p < 0.05). The adjusted HR of mortality remained elevated for any kidney disease (HR = 1.25; 95%CI = 1.09–1.45) and ESKD (HR = 1.38; 95%CI = 1.10–1.74).

Discussion: Kidney disease, especially ESKD, is associated with mortality among adults with CP independent of comorbidities that are relevant to CP and kidney disease. Findings suggest that nephrology care should be considered as part of routine clinical care for this population.

When Movement Moves: Study Protocol for a Multi-Method Pre/Post Evaluation Study of Two Programmes; the Danish Team Twin and Cycling Without Age

Physical activity (PA) can improve physical, mental, and social health, leading to quality of life (QoL). However, some are unable to participate independently due to age-related impairments or disabilities. This study protocol presents the design, methods, outcomes, strengths and limitations of the study “When Movement Moves” (WMM). WMM investigates whether indirect PA in a social context, where persons are unable to participate independently, can result in outcomes similar to those of independent PA, by evaluating the effects of disabled’s, elderly, volunteers’, relatives’ and nursing staff’s participation in either the running programme (Team Twin) or cycling programme (Cycling Without Age). Both programmes seek to enhance QoL through indirect PA in a social context, making PA possible for elderly and disabled persons through PA conducted by abled-bodied volunteers. WMM is a multi-method 12–16-week pre/post evaluation with quality of life, physical, mental and social health as main outcomes. Pre/post measurements consist of questionnaires, clinical examinations, and physical and cognitive appraisal. Throughout, interviews and participant observations will be conducted. Combined results will provide essential knowledge on the effects and experiences of indirect PA. Explorative data will pave the way for further research. Findings may inform policies, guidelines and health promotion among the elderly and disabled.

Navigating the Pathway to Care in Adults With Cerebral Palsy

As individuals with cerebral palsy (CP) age, they face unique challenges which complicate their ability to access and receive appropriate health care. These problems exist at the level of the health care system, the clinician, and the individual. At the system level, there is an inadequate number of professionals who are informed of and interested in the care of adults with CP. Pediatric clinicians prefer treating children, and adult caregivers are not knowledgeable about and may feel less competent about CP. Pediatric care does not translate well to the adult population, and information about best practices for adults is just starting to develop. Differences in the physiologic development of individuals with CP render well-established clinical protocols for risk screening of chronic diseases less effective. Moreover, lack of supportive resources decreases a caregiver's sense of self-efficacy in treating this population. The patient's ability to navigate these barriers is complicated by the high prevalence of comorbid cognitive impairment and mental health issues including anxiety, depression, and other psychiatric disorders; a bidirectional relationship between challenges in navigating care/needs and comorbid mental health conditions appears likely. Many patients have additional barriers related to social determinants of health, such as access to transportation, accessible health care facilities, and other personal and environmental factors that may impede health maintenance and wellness. Increasing and disseminating knowledge, harnessing the power of new technologies such as telemedicine, and addressing mental health issues are some of the methods that are available to help adults with CP navigate this road.

Polypharmacy is a risk factor for mortality, severe chronic kidney disease, and liver disease among privately insured adults with cerebral palsy

BACKGROUND: Adults with cerebral palsy (CP) have an increased risk for polypharmacy, premature mortality, and early development of several morbidities, including conditions associated with excess medication exposure, such as chronic kidney disease (CKD) and liver disease. To date, very little is known about the consequence of polypharmacy for adults with CP. OBJECTIVE: To determine if polypharmacy is associated with an increased risk for mortality, severe CKD, and liver disease among adults with CP, before and after adjusting for comorbid neurodevelopmental disabilities (NDDs) and multimorbidity. METHODS: This is an exploratory treatment effectiveness study. Data from the Optum Clinformatics Data Mart were used for this retrospective cohort study. Adults aged 18 years or older with a diagnosis of CP and without severe CKD (stages IV+) and liver disease were identified from the calendar year 2013 and were subsequently followed from January 1, 2014, to death, severe CKD, liver disease, loss to follow-up, or end of study period (December 31, 2017). Diagnosis codes were used to identify NDDs (intellectual disabilities, epilepsy, autism spectrum disorders, spina bifida) and 24 relevant morbidities at baseline (i.e., calendar year 2013). Polypharmacy was defined as ≥ 5 medications and hyperpolypharmacy was defined as ≥ 10 medications at baseline. Cox regression models were developed to examine the association (as HR and 95% CI) between polypharmacy and hyperpolypharmacy with mortality, severe CKD, and liver disease separately, before and after adjusting for covariates (demographics, NDDs, multimorbidity). Exploratory analyses examined the mediating effect of incident severe CKD or liver disease on the association between the exposure (polypharmacy or hyperpolypharmacy) on outcomes. RESULTS: Of the 9,238 adults with CP, 58.5% had polypharmacy and 29.5% had hyperpolypharmacy. The fully adjusted HR for mortality was 2.14 (95% CI = 1.59-2.89) for polypharmacy and 1.65 (95% CI = 1.31-2.09) for hyperpolypharmacy. The fully adjusted HR for severe CKD was 1.66 (95% CI = 1.17-2.36) for polypharmacy and 1.67 (95% CI = 1.27-2.19) for hyperpolypharmacy. The fully adjusted HR for liver disease was 1.57 (95% CI = 1.27-1.94) for polypharmacy and 1.72 (95% CI = 1.42-2.08) for hyperpolypharmacy. Incident liver disease mediated 5.37% (polypharmacy) and 7.54% (hyperpolypharmacy) of the association between the exposure with incident severe CKD for nonelderly (aged < 65 years), while incident severe CKD mediated 7.05% (polypharmacy) and 6.64% (hyperpolypharmacy) of the association between the exposure with incident liver disease for elderly (aged ≥ 65 years). CONCLUSIONS: Polypharmacy and hyperpolypharmacy are robust risk factors for risk of mortality, severe CKD, and liver disease among privately insured adults with CP. While incidence of severe CKD and liver disease had negligible effects on the association between polypharmacy with mortality, there is evidence that they mediate a considerable portion of one another and require further examination.

Barriers and facilitators of physical activity participation for young people and adults with childhood-onset physical disability: a mixed methods systematic review

AIM

To understand the attitudes, barriers, and facilitators to physical activity participation for young people and adults with childhood-onset physical disability.

METHOD

Seven electronic databases (Embase, MEDLINE, PsychINFO, AMED, CINAHL, SPORTDiscus, and ERIC) were searched to November 2019. English language studies were included if they investigated attitudes, barriers, or facilitators to physical activity for young people (≥15y) or adults with childhood-onset physical disabilities. Two reviewers applied eligibility criteria and assessed methodological quality. Data were synthesized in three stages: (1) thematic analysis into descriptive themes, (2) thematic synthesis via conceptual framework, and (3) an interpretive synthesis of the thematic results.

RESULTS

Nineteen studies were included. Methodological quality varied, with only four qualitative studies and one quantitative study meeting all quality items. An overarching theme of 'finding the right balance' emerged. Six subthemes relating to capability, opportunity, and motivation contributed to physical activity participation being seen as 'the right fit' or 'all too hard'. The interpretive synthesis found social connections, social environment support, and an appropriate physical environment were essential to 'finding the right balance' to be physically active.

INTERPRETATION

Physical activity participation for young people and adults with childhood-onset physical disabilities is primarily influenced by the social and physical environment. What this paper adds Physical activity participation for young people and adults with childhood-onset physical disabilities is primarily influenced by environmental factors. 'Finding the right balance' between enabling and inhibitory factors was important to physical activity participation being perceived as 'the right fit'. The opportunity for social connection is an important motivator for physical activity participation for young people and adults. The physical environment continues to act as a barrier to physical activity participation for those with physical disabilities.

Timecourse of Morbidity Onset Among Adults Living With Cerebral Palsy

INTRODUCTION

Despite the greater risk of an array of morbidities, little is known about when morbidities occur for adults with cerebral palsy. The objective of this study is to determine the timecourse of morbidity risk/development for adults with cerebral palsy and the effect by patient-level factors.

METHODS

Cross-sectional data from 2016 were used from a random 20% sample from the fee-for-service Medicare database. Diagnosis codes identified adults aged ≥18 years with cerebral palsy and 16 clinically relevant morbidities. Qualitative and quantitative approaches identified the age where each morbidity became exceedingly prevalent. The effect of the timecourse by sex, race, and co-occurring intellectual disabilities and epilepsy was examined. Data were sequestered and analyzed in 2020.

RESULTS

Among 16,818 adults with cerebral palsy, the prevalence of most morbidities was already high among those aged 18-30 years, and all morbidities increased with age except liver disease and anxiety. Hypertension and diabetes exhibited a positive linear trend with age. Of the morbidities that did not exhibit a linear trend, the qualitative and quantitative approaches were consistent considering that the cardiorespiratory diseases, osteoarthritis, renal disease, and dementia became exceedingly more prevalent at age >50 years, whereas the threshold was >60 years for depression, cancer, and metastatic cancer. There were interactions with sex, race, and co-occurring intellectual disabilities and epilepsy for some of the morbidities.

CONCLUSIONS

Morbidity prevalence is already elevated early in adulthood among individuals living with cerebral palsy, with an abrupt increase by age 50 years. Preventive efforts should be adopted early in the lifespan and not later than age 50 years for adults with cerebral palsy.

Whitney Comorbidity Index to monitor health status for adults with cerebral palsy: validation and thresholds to assist clinical decision making

AIM

To validate the Whitney Comorbidity Index (WCI), which was recently developed to monitor disease status for adults with cerebral palsy (CP), and to identify WCI scores associated with an increased mortality risk using a representative sample of adults with CP.

METHOD

Data from 2016 to 2018 were used from a random 20% sample from the fee-for-service Medicare database for this retrospective cohort study. The WCI was examined as unweighted (WCI_unw ) and weighted (WCI_w ) among adults at least 18 years old with CP. Cox regression models were developed with mortality as the outcome after adjusting for demographics. A concordance statistic (C-statistic) of at least 0.70 was considered as showing sufficient validity. The hazard ratio of mortality for each WCI score was estimated. Secondary analyses were performed for subgroups with co-occurring epilepsy and/or intellectual disabilities.

RESULTS

For the entire group (n=16 728) and subgroups, the WCI showed sufficient validity (C-statistic 0.73-0.81). For the entire group, the mortality rate was elevated for a score of 1 compared with 0 from the WCI_unw (hazard ratio 3.06; 95% confidence interval [CI] 1.52-6.17) and WCI_w (hazard ratio 4.08; 95% CI 1.69-9.85), and became larger with each WCI score. Results were similar for the subgroups.

INTERPRETATION

The WCI is a valid marker for health/disease status for adults with CP. Several WCI score thresholds were identified to assist in clinical decision making for preventive medicine and intervention implementation. What this paper adds The Whitney Comorbidity Index (WCI) is valid among 16 728 adults with CP. The WCI is valid for those with co-occurring epilepsy and/or intellectual disabilities. Thresholds of the WCI score were identified to assist clinical decision making.

Motor-learning based activities may improve functional ability in adults with severe cerebral palsy: A controlled pilot study

BACKGROUND

Cerebral palsy (CP) is a neurodevelopmental disturbance characterized by impaired control of movement. Function often decreases and 15% of adults are classified as severely affected (Gross Motor Function Classification Scale III-V). Little is known about interventions that aim to improve functional abilities in this population.

OBJECTIVE

To evaluate a 12-week intervention based on motor learning principles on functional ability in adults with severe CP.

METHODS

16 adults (36±10 years, GMFCS III-V) were enrolled and divided into an intervention group (Active group) and a standard care group (Control group). Primary outcome measure was Gross Motor Function Measure (GMFM-88). Secondary measures were neurological status. The Active group were measured at baseline, after the intervention and at one-month follow-up. The Control group were measured at baseline and after one month.

RESULTS

Analysis showed statistically significant improvement in GMFM-88 for the Active group from baseline to post assessment compared with the Control group (group difference: 5 points, SE 14.5, p = 0.008, CI: 1.2 to 8.7). Improvements were maintained at follow-up. Results from the neurological screening showed no clear tendencies.

CONCLUSIONS

The study provides support that activities based on motor learning principles may improve gross motor function in adults with severe CP.

Do physical activity interventions influence subsequent attendance and involvement in physical activities for children with cerebral palsy: a systematic review

PURPOSE

To investigate if children with cerebral palsy have sustained attendance and involvement in physical activities after completing physical activity interventions.

METHODS

The Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were followed. Seven databases were searched for the period 2001-2020 with hand-searching of pertinent reference lists. Criteria for study inclusion were participants aged 0-18 years and ≥50% with cerebral palsy; follow-up ≥1 month beyond completion of the physical activity intervention; and measurement of attendance and/or involvement in any physical activity post-intervention. Study selection, data extraction, and risk of bias assessments (Physiotherapy Evidence Database (PEDro) or tool for non-randomised studies) were completed independently by paired reviewers. Results were compiled by narrative synthesis.

RESULTS

Thirteen studies were included (11 randomised controlled trials (RCTs), two non-randomised case series; intervention sample sizes: 6-34). All study participants had cerebral palsy and were aged 4-16.7 years. PEDro scores for the RCTs ranged from 5 to 10; 10 did not blind one or more therapist, participant, or assessor. Two case series showed high risk of bias. Twelve studies reported on attendance, with positive changes in three studies. At 4-14 weeks post-intervention, two studies demonstrated positive changes were maintained. Four studies included involvement outcomes; one reporting positive changes in physical activity involvement four weeks after intervention completion.

CONCLUSIONS

Physical activity attendance may be influenced by physical activity interventions in the short term, but more robust research designs are required to investigate whether gains can be sustained. Activity involvement, which may influence ongoing participation, is under-researched.Implications for RehabilitationPositive changes in attendance and involvement following physical activity interventions appear short term at best.Physical activity interventions should have longer follow-up periods to determine the effect on sustained physical activity participation.Careful selection and reporting of attendance and involvement outcome measures is required.The optimal physical activity intervention to increase attendance or involvement in physical activities remains uncertain.

Increased Ankle Plantar Flexor Stiffness Is Associated With Reduced Mechanical Response to Stretch in Adults With CP

Hyperexcitable stretch reflexes are often not present despite of other signs of spasticity in people with brain lesion. Here we looked for evidence that increased resistance to length change of the plantar flexor muscle-fascicles may contribute to a reduction in the stretch reflex response in adults with cerebral palsy (CP). A total of 17 neurologically intact (NI) adults (mean age 36.1; 12 female) and 13 ambulant adults with CP (7 unilateral; mean age 33.1; 5 female) participated in the study. Subjects were seated in a chair with the examined foot attached to a foot plate, which could be moved by a computer-controlled electromotor. An ultrasound probe was placed over the medial aspect of the leg to measure the length of medial gastrocnemius muscle fascicles. Slow (7 deg/s) and fast (200 deg/s) stretches with amplitude 6 deg of the plantar flexors were applied over an ankle range of 70 deg at 10 deg intervals between 60 and 130 deg plantarflexion. It was checked by EMG electrodes that the slow stretches were sufficiently slow not to elicit any activity and that the fast stretches were sufficiently quick to elicit a maximal stretch reflex in both groups. The torque elicited by the stretches was measured together with changes in the length of medial gastrocnemius muscle fascicles. Muscle fascicles increased significantly in length with increasing dorsiflexion position in both populations (p < 0.001), but the fascicles were shorter in the CP population at all positions. Slow stretches elicited significantly larger torque and significantly smaller length change of muscle fascicles as the ankle joint position was moved more towards dorsiflexion in CP than in NI (p < 0.001). Fast stretches elicited larger torque responses at ankle joint positions of 80–100 deg in the NI than in the CP group (p < 0.01). A significant negative correlation was observed between the torque response and muscle fascicle length change to slow stretch in CP (p < 0.05), but not in NI. These findings support that increased passive resistance of the ankle plantar flexor muscle-tendon unit and development of contractures may conceal stretch reflex response in adults with CP. We argue that this should be taken into account in the neurological examination of spasticity.

A Life Course Perspective on Growing Older With Cerebral Palsy

Despite most children with cerebral palsy (CP) now living within typical life spans, little is known about how the effects of CP unfold across the life course and impact participation in everyday life during adulthood. In this study, we explored the experiences of 38 adults growing older with CP. Data were gathered using semi-structured interviews focused on participants' engagement in activities in their community and analyzed using a life course perspective to deepen our understanding of the experiences of our participants. We found that individual agency, family and social contexts, as well as larger sociocultural contexts all shaped participants' experiences as they grew older. The findings highlight the usefulness of the life course perspective for understanding how the effects of a diagnosis of CP unfold over time. Further use of this perspective can better inform health care services to meet the needs of adults with CP aging with a lifelong disability.

Development of a new comorbidity index for adults with cerebral palsy and comparative assessment with common comorbidity indices

AIM

To develop a new comorbidity index for adults with cerebral palsy (CP), the Whitney Comorbidity Index (WCI), which includes relevant comorbidities for this population and better predicts mortality than the Charlson Comorbidity Index (CCI) and Elixhauser Comorbidity Index (ECI).

METHOD

Data from the Optum Clinformatics Data Mart was used for this retrospective cohort study. Diagnosis codes were used to identify adults aged 18 years or older with CP (n=1511 females, n=1511 males; mean [SD; range] age=48y [19y 2mo; 18-89y]) and all comorbidities in the year 2014. The WCI was developed based on the comorbidities of the CCI and ECI and other relevant comorbidities associated with 2-year mortality using Cox regression and competing risk analysis. The WCI was examined as unweighted (WCI_unw ) and weighted (WCI_w ). The model fit and discrimination (C-statistic) of each index was assessed using Cox regression.

RESULTS

Twenty-seven comorbidities were included in the WCI; seven new comorbidities that were not part of the CCI or ECI were added. The WCI_unw and WCI_w showed a better model fit and discrimination for 1- and 2-year mortality compared to the CCI and ECI. The WCI_unw and WCI_w were strong predictors for 1- and 2-year mortality (C-statistic [95% confidence interval] ranging from 0.81 [0.76-0.85] to 0.88 [0.82-0.94]).

INTERPRETATION

The new WCI, designed to include clinically relevant comorbidities, provides a better model fit and discrimination of mortality for adults with CP.

WHAT THIS PAPER ADDS

Common comorbidity indices exclude relevant comorbidities for adults with cerebral palsy (CP). A new comorbidity index for adults with CP was created by harmonizing clinical theory and data-driven methods. The Whitney Comorbidity Index better predicted 1- and 2-year mortality than other commonly used comorbidity indices.

The paradoxical relationship between severity of cerebral palsy and renal function in middle-aged adults: better renal function or inappropriate clinical assessment?

PURPOSE

To determine the association between severity of cerebral palsy with serum creatinine (sCr) and sCr-based equations to estimate glomerular filtration rate (eGFR), a marker of renal function.

METHODS

A clinic-based sample of 30-64 year-olds with cerebral palsy was examined and stratified by motor impairment: gross motor function classification system (GMFCS) I/II (n = 79), GMFCS III (n = 78), and GMFCS IV/V (n = 137). sCr, which is influenced by muscle mass, was obtained and sCr-based eGFR was calculated using the Modification of Diet in Renal Disease (MDRD) and Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equations.

RESULTS

sCr was lower with increasing GMFCS. The opposite pattern was observed for eGFR: GMFCS IV/V had significantly higher eGFR derived from MDRD compared to other GMFCS groups; GMFCS III had significantly higher eGFR compared to GMFCS I/II. The pattern was similar for CKD-EPI derived eGFR.

CONCLUSIONS

According to widely used clinical assessment methods for renal function, higher severity of cerebral palsy among adults is associated with better renal function, which is incongruent with their other biological systems. This paradoxical relationship is likely driven by lower muscle rather than true renal function, and thus, sCr-based eGFR may overestimate renal function, especially for GMFCS IV/V. Further prospective studies are needed.Implications for rehabilitationCommon methods of clinical assessment may over-estimate renal function for adults with cerebral palsy (CP), potentially giving a false positive for normal renal health due to their reliance on muscle mass.This study of a clinic-based sample of middle-aged adults with CP highlights the paradoxical relationship between severity of CP and renal function, which is likely driven by methodological limitations in the presence of low muscle mass rather than actual better renal function.It is recommended that clinicians have a high suspicion of abnormal renal function and the need for a nephrology consultation, especially with changes in creatinine levels, even within the normal range.Rehabilitation for adults with CP must have a strong focus on muscle and kidney health, especially for patients with more severe forms of CP.

Adults with Cerebral Palsy Require Ongoing Neurologic Care: A Systematic Review

Cerebral palsy (CP) neurologic care and research efforts typically focus on children. However, most people with CP are adults. Adults with CP are at increased risk of new neurologic conditions, such as stroke and myelopathy, that require ongoing neurologic surveillance to distinguish them from baseline motor impairments. Neurologic factors could also contribute to the motor function decline, chronic pain, and chronic fatigue that are commonly experienced by adults with CP. Based on a systematic literature review, we suggest (1) guidelines for neurologic surveillance and neurologist referral and (2) clinical research questions regarding the evolving neurologic risks for adults with CP.

Timing of Co-occurring Chronic Conditions in Children With Neurologic Impairment

BACKGROUND

Children with neurologic impairment (NI) are at risk for developing co-occurring chronic conditions, increasing their medical complexity and morbidity. We assessed the prevalence and timing of onset for those conditions in children with NI.

METHODS

This longitudinal analysis included 6229 children born in 2009 and continuously enrolled in Medicaid through 2015 with a diagnosis of NI by age 3 in the IBM Watson Medicaid MarketScan Database. NI was defined with an existing diagnostic code set encompassing neurologic, genetic, and metabolic conditions that result in substantial functional impairments requiring subspecialty medical care. The prevalence and timing of co-occurring chronic conditions was assessed with the Agency for Healthcare Research and Quality Chronic Condition Indicator system. Mean cumulative function was used to measure age trends in multimorbidity.

RESULTS

The most common type of NI was static (56.3%), with cerebral palsy (10.0%) being the most common NI diagnosis. Respiratory (86.5%) and digestive (49.4%) organ systems were most frequently affected by co-occurring chronic conditions. By ages 2, 4, and 6 years, the mean (95% confidence interval [CI]) numbers of co-occurring chronic conditions were 3.7 (95% CI 3.7-3.8), 4.6 (95% CI 4.5-4.7), and 5.1 (95% CI 5.1-5.2). An increasing percentage of children had ≥9 co-occurring chronic conditions as they aged: 5.3% by 2 years, 10.0% by 4 years, and 12.8% by 6 years.

CONCLUSIONS

Children with NI enrolled in Medicaid have substantial multimorbidity that develops early in life. Increased attention to the timing and types of multimorbidity in children with NI may help optimize their preventive care and case management health services.

Is Stem Cell Therapy the New Savior for Cerebral Palsy Patients? A Review

Cerebral Palsy (CP) is one of the foremost causes of childhood motor disability and disrupts the individual's development and ability to function. Several factors contribute to the development of CP such as preterm delivery, low birth weight, infection/inflammation, and additional pregnancy complications, both in preterm and term infants. As there is no specific treatment for CP, rehabilitation is the current option for the management of patients. The serious nature of this condition creates deficits that last a lifetime. 

We collected studies that were published in the past 10 years, using PubMed as our main database. We chose studies that were relevant to CP and stem cell therapy. We mainly focused on various types of stem cells that can be used in treatment, mechanism of action (MOA) of stem cells, routes, dosage, and adverse effects, their efficacy, and safety in CP patients. Of all the 38 studies we reviewed, we found that five articles discussed the utilization of human umbilical cord blood [hUCB], four articles discussed autologous bone marrow stem cells, and one discussed allogeneic umbilical cord blood usage. One article discussed neural stem-like cells (NSLCs) derived from bone marrow and the remaining 27 articles were about CP and its treatment.

We reviewed detailed information about the possible stem cell therapies and their benefits in patients with CP. We found that immune modulation is the major mechanism of action of stem cells, and among all the types of stem cells. Autologous umbilical cord mesenchymal stem cells appear to be safe and most effective in treatment compared to other stem cell treatments. Among all symptoms, motor symptoms are best corrected by stem cell therapy. Still, it did not show any marked improvement in treating other symptoms like speech defects, sensory or cognitive defects, or visual impairment.
