Aim: To determine if pain is associated with 12-month incidence of mood affective disorders (MAD) in adults with cerebral palsy (CP).Method: Data from Optum Clinformatics® Data Mart (2013-2016) were used for this retrospective cohort study. Diagnostic codes were used to identify adults (≥18y) with CP, incident cases of MAD, and covariates (other neurodevelopmental conditions, sleep disorders, arthritis). Pain (any type, location) was identified between 1st October 2014 and 30th September 2015. The pain group was divided into new or consistent pain if they had a history of pain (i.e. consistent) in the 12 months before their first pain claim date. Crude incidence rates of MAD (expressed per 100 person-years) were estimated. Cox regression was used to estimate hazard ratio (95% confidence interval [CI]) of MAD after adjusting for covariates.Results: Adults that had new pain (n=859; incidence rate=15.5) or consistent pain (n=1303; incidence rate=17.9) had greater crude incidence rate of MAD compared to adults without pain (n=3726; incidence rate=5.9). The elevated rate of MAD remained after adjusting for covariates, for new pain (hazard ratio=2.4; 95% CI=1.9-3.0) and consistent pain (hazard ratio=2.1; 95% CI=1.7-2.7).Interpretation: Pain is associated with greater incidence of MAD in adults with CP. This association remained after accounting for potential confounding factors.What This Paper Adds: What this paper adds Pain was associated with higher 12-month incidence of mood affective disorders (MAD). The 12-month MAD incidence was similar between new and consistent pain groups. The MAD incidence remained higher adjusting for neurodevelopmental comorbidities, sleep disorders, and arthritis.

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 (WCIunw ) and weighted (WCIw ) 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 WCIunw (hazard ratio 3.06; 95% confidence interval [CI] 1.52-6.17) and WCIw (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. [ABSTRACT FROM AUTHOR]

Aim: To determine if walking ability and presence of intellectual disability and epilepsy change from childhood to 50 years of age in individuals with cerebral palsy (CP), and if such changes are related to age, sex, or CP subtype.Method: This was a population-based follow-up study of 142 adults born from 1959 to 1978 (82 males, 60 females; mean age 48y 4mo, range 37-58y; 44% unilateral, 35% bilateral, 17% dyskinetic, and 4% ataxic CP) listed in the CP register of western Sweden. We compared childhood data with a follow-up assessment in 2016.Results: At follow-up, walking ability had changed significantly (p<0.001). The proportion of participants walking without aids had decreased from 71% to 62%, and wheelchair ambulation increased from 18% to 25%. Walking ability was related to subtype (p=0.001), but not to age, sex, pain, fatigue, or body mass index. The proportion classified as having intellectual disability had increased from 16% to 22% (p=0.039) and the proportion with epilepsy from 9% to 18% (p=0.015). Of those with childhood epilepsy, 46% were seizure-free without medication.Interpretation: Walking ability and the presence of intellectual disability and epilepsy had changed significantly since childhood. Life-long access to specialized health care is warranted for re-evaluation of impairments, treatment, and assistance. What this paper adds Changes in impairments in individuals with cerebral palsy (CP) over time are related to CP subtype. After 50 years, walking ability in CP may have deteriorated or improved. Intellectual disability in CP may not always be detected in early childhood assessments. Epilepsy in CP may develop after childhood or may be outgrown. [ABSTRACT FROM AUTHOR]

Aim: We explored the psychometric properties of the recently developed Tyneside Pegboard Test (TPT) for unimanual and bimanual dexterity in children with unilateral cerebral palsy (CP) and investigated the impact of sensorimotor impairments on manual dexterity.Method: In this cross-sectional study, the TPT was assessed in 49 children with unilateral CP (mean age 9y 8mo, SD 1y 11mo, range 6-15y; 30 males, 19 females; 23 with right unilateral CP). All participants additionally underwent a standardized upper limb evaluation at body function and activity level. We investigated: (1) known-group, concurrent, and construct validity and (2) impact of sensorimotor impairments including spasticity, grip force, stereognosis, and mirror movements using analysis of covariance, Spearman's rank correlation (r), and multiple linear regression (R2 ) respectively.Results: TPT outcomes significantly differed according to the Manual Ability Classification System (p<0.001, known-group validity). Relationships were found between the unimanual TPT tasks and the Jebsen-Taylor Hand Function Test (r=0.86-0.88, concurrent validity). Bimanual TPT tasks were negatively correlated with the Assisting Hand Assessment, ABILHAND-Kids, and Children's Hand-use Experience Questionnaire (r=-0.38 to -0.78, construct validity). Stereognosis was the main determinant influencing all tasks (p<0.001, R2 =37-50%). Unimanual dexterity was additionally determined by grip strength (p<0.05, R2 =8-9%) and mirror movements in the more impaired hand (p<0.05, R2 =4-8%). Bimanual dexterity was also explained by mirror movements in the more impaired hand (p<0.01, R2 =10-16%) and spasticity (p=0.04, R2 =5%).Interpretation: The TPT is a valid test to measure unimanual and bimanual dexterity in unilateral CP. The results further emphasize the importance of somatosensory impairments in children with unilateral CP. What this paper adds The Tyneside Pegboard Test is valid for measuring unimanual and bimanual dexterity in unilateral cerebral palsy. Children with poorer manual ability show worse unimanual and bimanual dexterity. Stereognosis is the main predictor of both unimanual and bimanual dexterity. Stronger mirror movements in the more impaired hand result in worse bimanual dexterity. [ABSTRACT FROM AUTHOR]

Aim: To evaluate the properties of the Infant Motor Activity Log (IMAL), a caregiver-report for frequency and quality of use of more affected upper extremity in infants with neurological and functional impairments.Method: This was a prospective cohort study of 66 children (34 females, 32 males) aged 6 to 24 months (mean age [SD] 13.7mo [5.3]) with neurological and functional impairments and a confirmed cerebral palsy diagnoses after 2 years, and 51 age-matched typically developing children. The IMAL was administered at baseline and 4 weeks later. Typically developing infants were tested with randomly assigned 'more affected' upper extremity. Psychometric properties were evaluated using Spearman's correlation coefficient, Cronbach's alpha, and Jonckheere-Terpstra tests.Results: In the children with impairments, the IMAL showed internal consistency (alpha≥0.88) for the How Well Scale (HWS) and How Often Scale (HOS). Test-retest reliability was 0.64 (HOS) and 0.70 (HWS), demonstrating stability over time. Correlation with Bayley Scales of Infant and Toddler Development, Third Edition more affected arm raw scores were 0.70 (HOS) and 0.72 (HWS) (p<0.001) demonstrating construct validity. Both scale scores decreased with increasing Gross Motor Function Classification System and Mini-Manual Ability Classification System (p<0.001) levels, supporting discriminative validity. Discrimination between typically developing infants and infants with impairments was high (HWS: area under the receiver operating characteristic curve [AUC] 0.96, 95% confidence interval [CI] 0.94-0.99 and HOS AUC=0.95, CI 0.92-0.99).Interpretation: The IMAL is a valid and reliable discriminative caregiver measure of upper limb performance and may complement measures of capacity in infants with neurological and functional impairments.What This Paper Adds: The Infant Motor Activity Log (IMAL) is a valid and reliable measure of caregiver perception of upper limb function. The IMAL fills a measurement gap for infant motor performance in children with impairments. The IMAL discriminates among motor function levels. [ABSTRACT FROM AUTHOR]

Aim: To describe the trajectory of clinical signs in children who developed human immunodeficiency virus encephalopathy (HIVE) after starting early antiretroviral therapy (ART).Method: This was a retrospective case-cohort description of HIVE among Cape Town participants from the Children with HIV Early AntiRetroviral treatment (CHER) trial. Criteria for HIVE diagnosis were at least two of: (1) acquired central motor deficit, (2) impaired brain growth, and (3) failure to attain or loss of developmental milestones in the absence of an alternative aetiology.Results: Of 133 surviving participants who initiated ART at a median age of 9 weeks and who were followed until a median age of 6 years, 20 (12%) developed HIVE at a median age 31 months (interquartile range 19-37). In these, the first neurological deterioration was noticed at a median age of 19 months, when 16 were on ART and nine had undetectable HIV viral load for a median of 12 months. Signs of upper motor neurons were present in 18, of whom 12 resolved and four had persistent spastic diplegia; 19 had motor delay, of whom 14 resolved; 12 had language delay, of whom 11 resolved; and 16 had impaired brain growth, of whom only five recovered. For the 16 participants already on ART at HIVE diagnosis, regimens were not altered in response to diagnosis.Interpretation: HIVE may occur despite early ART initiation and virological suppression and then resolve on unchanged ART, most likely as intrathecal inflammation subsides.What This Paper Adds: Despite suppressive antiretroviral therapy, children can develop human immunodeficiency virus encephalopathy, The most common manifestations are motor deficits and impaired brain growth. Most experience improvement, with many resolving without additional intervention. [ABSTRACT FROM AUTHOR]

Aim: To examine the efficacy of Hand-Arm Bimanual Intensive Therapy (HABIT) on daily functioning, unimanual dexterity, and bimanual performance of children with bilateral cerebral palsy (CP) compared with customary care.Method: Forty-one children with bilateral CP, aged 4 to 16 years, classified in levels I to III of the Manual Ability Classification System, were randomly assigned to HABIT (90h) (n=21) or to customary care (4.5h) (n=20). Participants' daily functioning (Pediatric Evaluation of Disability Inventory [PEDI], Canadian Occupational Performance Measure [COPM]), unimanual dexterity (Jebsen-Taylor Test of Hand Function, Box and Blocks Test [BBT]), and bimanual performance (Both Hands Assessment) were assessed pre-, post-, and 6 months after the intervention. Linear mixed-effects models were used for inferential analysis.Results: Children participating in HABIT showed greater improvements in daily functioning (COPMperformance : χ12 =9.50, p<0.01; COPMsatisfaction : χ12 =5.07, p<0.05; PEDIfunctional skills : χ12 =6.81, p<0.01; PEDIcaregiver assistance : χ12 =6.23, p<0.05) and in the dexterity of the dominant hand (BBT: χ12 =3.99, p<0.05) compared with children maintaining customary care. Group or time effects did not explain any variance in bimanual performance or in the dexterity of the non-dominant hand.Interpretation: HABIT may be beneficial for children with bilateral CP, with benefits evidenced for daily functioning outcomes.What This Paper Adds: Hand-Arm Bimanual Intensive Therapy (HABIT) improved daily functioning of children with bilateral cerebral palsy (CP). Bimanual performance, measured by the Both Hands Assessment, did not change after HABIT in children with bilateral CP. Children with asymmetric and symmetric hand use exhibited similar improvements after HABIT. [ABSTRACT FROM AUTHOR]

Aim: To evaluate pain prevalence and characteristics in children and adolescents with predominant dyskinetic and mixed (dyskinetic/spastic) cerebral palsy (CP) motor types.Method: Seventy-five participants with a diagnosis of CP and confirmed dyskinetic or mixed (dyskinetic/spastic) motor type took part in a multisite cross-sectional study. The primary outcome was carer-reported pain prevalence (preceding 2wks) measured using the Health Utilities Index-3. Secondary outcomes were chronicity, intensity, body locations, quality of life, and activity impact.Results: Mean participant age was 10 years 11 months (SD 4y 2mo, range 5-18y). There were 44 males and 31 females and 37 (49%) had predominant dyskinetic CP. Pain was prevalent in 85% and it was chronic in 77% of participants. Fifty-two per cent experienced moderate-to-high carer-reported pain intensity, which was significantly associated with predominant dyskinetic motor types (p=0.008). Pain occurred at multiple body locations (5 out of 21), with significantly increased numbers of locations at higher Gross Motor Function Classification System levels (p=0.02). Face, jaw, and temple pain was significantly associated with predominant dyskinetic motor types (p=0.005). Poorer carer proxy-reported quality of life was detected in those with chronic pain compared to those without (p=0.03); however, chronic pain did not affect quality of life for self-reporting participants.Interpretation: Pain was highly prevalent in children and adolescents with predominant dyskinetic and mixed (dyskinetic/spastic) motor types, highlighting a population in need of lifespan pain management.What This Paper Adds: Chronic pain prevalence in children and adolescents with predominant dyskinetic and mixed (dyskinetic/spastic) motor types is high. Pain occurs across multiple body locations in predominant dyskinetic and mixed (dyskinetic/spastic) motor types. Less recognized locations of pain include the face, jaw, and temple for predominant dyskinetic motor types. [ABSTRACT FROM AUTHOR]

Aim: To evaluate the effect of progressive resistance training of the ankle plantarflexors on gait efficiency, activity, and participation in adolescents with cerebral palsy (CP).Method: Sixty-four adolescents (10-19y; 27 females, 37 males; Gross Motor Function Classification System [GMFCS] levels I-III) were randomized to 30 sessions of resistance training (10 supervised and 20 unsupervised home sessions) over 10 weeks or usual care. The primary outcome was gait efficiency indicated by net nondimensional oxygen cost (NNcost). Secondary outcomes included physical activity, gross motor function, participation, muscle strength, muscle and tendon size, and muscle and tendon stiffness. Analysis was intention-to-treat.Results: Median attendance at the 10 supervised sessions was 80% (range 40-100%). There was no between-group difference in NNcost at 10 (mean difference: 0.02, 95% confidence interval [CI] -0.07 to 0.11, p=0.696) or 22 weeks (mean difference: -0.08, 95% CI -0.18 to 0.03, p=0.158). There was also no evidence of between-group differences in secondary outcomes at 10 or 22 weeks. There were 123 adverse events reported by 27 participants in the resistance training group.Interpretation: We found that 10 supervised sessions and 20 home sessions of progressive resistance training of the ankle plantarflexors did not improve gait efficiency, muscle strength, activity, participation, or any biomechanical outcome among adolescents with CP.What This Paper Adds: Thirty sessions of progressive resistance training of the ankle plantarflexors over 10 weeks did not improve gait efficiency among ambulatory adolescents with cerebral palsy. Resistance training did not improve muscle strength, activity, or participation. Ninety percent of participants experienced an adverse event. Most adverse events were expected and no serious adverse events were reported. [ABSTRACT FROM AUTHOR]

Aim: To describe trends in gastrostomy tube insertion in children with developmental or acquired disorders in Sweden and assess their demographic characteristics.Method: Children aged 0 to 18 years with gastrostomy tube insertions recorded between 1998 and 2014 were identified in the Swedish National Patient Register. Associations between disorder type and year of surgery, as well as age at surgery, were analysed using linear regression analyses. The association between disorder type and mortality 2 years from gastrostomy tube insertion was also analysed using logistic regression analysis.Results: The data for 4112 children (2182 males, 1930 females), with a median age of 2 years (interquartile range=1-8y), were analysed. Children who presented with developmental disorders were the largest group (n=3501, 85%). The most common diagnosis in children with developmental disorders was cerebral palsy (n=165, 4%). In children with acquired disorders, acute lymphoblastic leukaemia (n=117, 3%) was the most common diagnosis. Gastrostomy tube insertions increased from 1998 to 2014, with the greatest increase in children with developmental disorders, who were younger than children with acquired disorders when the gastrostomy tube was first inserted. Age at tube insertion decreased in both groups during the study period. Mortality was higher in children with acquired disorders, suggesting that gastrostomy tube insertion should be part of a palliative care approach.Interpretation: Child characteristics differed depending on whether the underlying disorder was developmental or acquired, suggesting a need for clinical health care guidelines related to the specific goals of gastrostomy tube insertion.What This Paper Adds: Gastrostomy tube insertions increased by 140% from 1998 to 2014 in Sweden. The age of children with developmental disorders decreased by 1 month per year during the study period. Children presenting with developmental disorders were younger than children with acquired disorders when the gastrostomy tube was first inserted. Mortality was higher in children with acquired disorders. [ABSTRACT FROM AUTHOR]

Aim: To explore how patients with cerebral palsy (CP) perceive their gait and evaluate associations between subjective gait perception and: objective gait parameters, endurance, pain, and fatigue.Method: Sixty-two patients (21 females and 41 males; mean [SD] age 20y [5y 1mo], range 15-29y) performed a clinical gait analysis. Self-selected walking speed, Gait Profile Score, and Gait Variable Score were calculated. Subjective gait perception was assessed with a visual analogue scale using the question: 'On a scale from 0 (worst) to 10 (optimal), how would you describe your walking today?'. A 6-minute walk test (6MWT) measured endurance; the 36-Item Short Form Health Survey (SF-36) evaluated quality of life. T-tests, Pearson correlations, and univariate and multiple linear regression models were used to compare and find associations between the data.Results: Overall mean (SD) subjective gait perception was 7.5 (1.8) and was significantly higher for patients in Gross Motor Function Classification System (GMFCS) level I (7.9 [1.5]) than for patients in GMFCS levels II and III (5.9 [2.0]). Positive correlations were found between subjective gait perception and gait scores, walking speed, 6MWT distance, and SF-36 score. Only walking speed was a significant predictor of subjective gait perception.Interpretation: Subjective gait perception was influenced by GMFCS level and linked partially with the walking speed. The gait quality did not explain subjective gait perception. It is important to combine subjective and objective gait scores to develop personalized therapeutic goals.What This Paper Adds: Subjective gait perception is influenced by the physical impairment levels of patients with cerebral palsy. Subjective gait perception and objective gait scores are associated. Walking speed is the only predictor of gait perception. [ABSTRACT FROM AUTHOR]

Aim: To: (1) investigate the relationship between upper-limb impairment and health-related quality of life (HRQoL) for children with cerebral palsy and (2) develop a mapping algorithm from the Cerebral Palsy Quality of Life Questionnaire for Children (CPQoL-Child) onto the Child Health Utility 9D (CHU9D) measure.Method: The associations between physical and upper-limb classifications and HRQoL of 76 children (40 females, 36 males) aged 6 to 15 years (mean age 9 years 7 months [SD 3y]) were assessed. Five statistical techniques were developed and tested, which predicted the CHU9D scores from the CPQoL-Child total/domain scores, age, and sex.Results: Most participants had mild impairments. The Manual Ability Classification System (MACS) level was significantly negatively correlated with CHU9D and CPQoL-Child (r=-0.388 and r=-0.464 respectively). There was a negative correlation between the Neurological Hand Deformity Classification (NHDC) and CPQoL-Child (r=-0.476, p<0.05). The generalized linear model with participation, pain domain, and age had the highest predictive accuracy.Interpretation: The weak negative correlations between classification levels and HRQoL measures may be explained by the restricted range of impairment levels of the participants. The MACS and NHDC explained the impact of upper-limb impairment on HRQoL better than the other classifications. The generalized linear model with participation, pain, and age is the suggested mapping algorithm. The suggested mapping algorithm will facilitate the use of CPQoL-Child for economic evaluation and can be used to conduct cost-utility analyses.What This Paper Adds: The Manual Ability Classification System and Neurological Hand Deformity Classification were the best predictors of health-related quality of life measures. Age and Cerebral Palsy Quality of Life Questionnaire for Children participation and pain domain scores can predict Child Health Utility 9D scores. [ABSTRACT FROM AUTHOR]

Aim: To assess the reliability and predictive validity of the developmental and socio-emotional scales of the Standardized Infant NeuroDevelopmental Assessment (SINDA).Method: To assess reliability, two sets of three assessors forming eight assessor-pairs independently rated the developmental and socio-emotional scales of 60 infants. To evaluate predictive validity, 223 infants (gestational age 30wks [range 23-41wks]; 117 males, 106 females) attending a non-academic outpatient clinic were assessed by different assessors with SINDA's neurological, developmental, and socio-emotional scales. Atypical neurodevelopmental outcome at a corrected age of 24 months or older implied a Bayley Mental or Psychomotor Developmental Index score of less than 70 or neurological disorder (including cerebral palsy). Behavioural and emotional disorders were classified according to the International Classification of Diseases, 10th Revision. Predictive values were calculated from SINDA (2-12mo corrected age, median 7mo) and typical versus atypical outcome, and for intellectual disability only (Mental Developmental Index <70).Results: Assessors highly agreed on the developmental and socio-emotional assessments (developmental scores: Spearman's rank correlation coefficient ρ=0.972; single socio-emotional behaviour items: Cohen's κ=0.783-0.896). At 24 months or older, 65 children had atypical outcome. Atypical neurological scores predicted atypical outcome (sensitivity 83%, specificity 96%); atypical developmental scores predicted intellectual disability (sensitivity 77%, specificity 92%). Atypical emotionality and atypical self-regulation were associated with behavioural and emotional disorders.Interpretation: SINDA's three scales are reliable, and have a satisfactory predictive validity for atypical developmental outcome at 24 months or older in a non-academic outpatient setting. SINDA's developmental scale has promising predictive validity for intellectual disability. SINDA's socio-emotional scale is a tool for caregiver counselling.What This Paper Adds: Standardized Infant NeuroDevelopmental Assessment (SINDA)'s developmental and socio-emotional scales have excellent interrater reliability. Replication of the satisfactory validity of SINDA's neurological scale for atypical outcome. [ABSTRACT FROM AUTHOR]

Aim: To compare anterior and posterior standing balance reactions, as measured by single-stepping thresholds, in children with and without spastic cerebral palsy (CP).Method: Seventeen ambulatory children with spastic CP (eight males, nine females) and 28 typically developing children (13 males, 15 females; age range 5-12y, mean [SD] 9y 2mo [2y 3mo]), were included in this cross-sectional, observational study. Balance reaction skill was quantified as anterior and posterior single-stepping thresholds, or the treadmill-induced perturbations that consistently elicited a step in that direction. In order to understand the underlying mechanisms of between-group differences in stepping thresholds, dynamic stability was quantified using the minimum margin of stability. Ankle muscle activation latency, magnitude, and co-contraction were assessed with surface electromyography.Results: We observed an age and group interaction for anterior thresholds (p=0.001, partial η2 =0.24). At older (≈11y; p<0.001, partial η2 =0.48), but not younger (≈7y; p=0.33, partial η2 =0.02) ages, typically developing children had larger anterior thresholds than those with CP. In response to near-threshold anterior perturbations, older typically developing children recovered from more instability than their peers with CP (p=0.004, partial η2 =0.18). Older children had no between-group differences in ankle muscle activity. No between-group differences were observed in posterior thresholds.Interpretation: The effects of CP on balance reactions are age- and direction-specific. Older typically developing children are more able or willing to withhold a step when unstable.What This Paper Adds: Children with spastic cerebral palsy have age- and direction-specific balance-reaction impairments. Lower anterior stepping thresholds were observed in older, but not younger children. Older typically developing children withheld a forward step at higher levels of instability. No between-group differences were seen in posterior stepping thresholds. [ABSTRACT FROM AUTHOR]

Aim: To explore cortical activation during bimanual tasks and functional correlates in unilateral cerebral palsy (CP).Method: This cross-sectional study included eight participants with unilateral CP (six females, two males; mean age [SD] 20y 10mo [5y 10mo], 13y 8mo-31y 6mo) in Manual Ability Classification System levels II to III and nine age-matched participants with typical development (seven females, two males; mean age [SD] 17y 8mo [5y 7mo], 9y 4mo-24y 2mo). They performed bimanual symmetric squeezing (BSS) and bimanual asymmetric squeezing (BAS) tasks at 1Hz, and a pouring task with dominant hand (DPour) and a pouring task with non-dominant hand (NDPour) at 0.67Hz, all while a custom array of functional near-infrared spectroscopy (fNIRS) optodes were placed over their sensorimotor area. Mixed-effects were used to contrast groups, tasks, and hemispheres (corrected p-values [q] reported). Analysis of variance and t-tests compared performance measures across groups and tasks.Results: Participants with unilateral CP showed greater activation in both hemispheres during BAS (non-lesioned: q<0.001; lesioned: q<0.001), and in the lesioned hemisphere during BSS (q<0.001), DPour (q=0.02), and NDPour (q=0.02) than those with typical development. The lesioned hemisphere in unilateral CP showed more activity than the non-lesioned one (BSS: q=0.01; BAS: q=0.009; NDPour: q=0.04). During BAS, higher cortical activity correlated with more synchronous arm activation (r=0.79; p=0.02); activity lateralized towards the non-lesioned hemisphere correlated with better Pediatric Evaluation of Disability Inventory computer adaptive test scores (r=0.81; p=0.03).Interpretation: Results suggest abnormally increased sensorimotor cortical activity in unilateral CP, with implications to be investigated.What This Paper Adds: Cortical activity in manual tasks is described with functional near-infrared spectroscopy in typical and atypical cohorts. Activation levels in unilateral cerebral palsy appear to escalate with task difficulty. Increased brain activity may be associated with poorer selective manual control. Specific patterns of brain activity may be related to impaired bimanual function. [ABSTRACT FROM AUTHOR]

Aim: To compare the rate of falls between adults with and without cerebral palsy (CP).Method: We used primary care data on 1705 adults with CP and 5115 adults without CP matched for age, sex, and general practice attended. We compared odds of experiencing a fall between adults with and without CP using conditional logistic regression. We compared the rate of falls using a negative binomial model.Results: Participants were 3628 males (53%) and 3192 females (47%) (median age 29y, interquartile range 20-42y) at the start of follow-up. Follow-up was 14 617 person-years for adults with CP and 56 816 person-years for adults without CP. Of adults with CP, 15.3% experienced at least one fall compared to 5.7% of adults without CP. Adults with CP had 3.64 times (95% confidence interval [CI] 2.98-4.45) the odds of experiencing a fall compared to adults without CP. The rate of falls was 30.5 per 1000 person-years and 6.7 per 1000 person-years for adults with and without CP respectively (rate ratio 5.83, 95% CI 4.84-7.02) INTERPRETATION: Adults with CP are more likely to fall, and fall more often, than adults without CP. The causes and consequences of falls in adults with CP need examination.What This Paper Adds: Twenty adults with CP and 5.3 adults without CP experienced at least one fall per 1000 person-years. Adults with CP experienced 30.5 falls per 1000 person-years compared to 6.7 falls per 1000 person-years among adults without CP. Adults with CP had 3.64 times the odds of experiencing a fall compared to adults without CP. Adults with CP experienced 5.83 times more falls than adults without CP. [ABSTRACT FROM AUTHOR]

Aim: To determine the proportion of children with cerebral palsy (CP) who had major congenital anomalies, describe the types of disorders, and report on the children's functional outcomes.Method: Data were extracted from the Bangladesh Cerebral Palsy Register (BCPR). Descriptive analyses were conducted on children with CP and major congenital anomalies. Odds ratios (ORs) with 95% confidence intervals (CIs) were calculated to measure the association between major congenital anomalies, clinical severity, and presence of comorbidities.Results: Between January 2015 and December 2016, 726 children with CP were newly registered with the BCPR (277 females, 449 males; mean age [SD] at registration 90mo [54mo], 4mo-18y). Seventy-eight children (11%) had a major congenital anomaly. Neurological (86%) and musculoskeletal congenital anomalies (10%) were the most common. Microcephaly was the most common congenital anomaly (83%). The odds of severe functional motor limitations (OR=2.4, 95% CI=1.9-2.9), epilepsy (OR=1.6, 95% CI=1.1-2.1), visual impairment (OR=2.6, 95% CI=2.0-3.2), presence of strabismus (OR=3.9, 95% CI=3.8-4.4), hearing (OR=1.2, 95% CI=0.6-1.9), speech (OR=5.4, 95% CI=4.6-6.2), and intellectual impairments (OR=2.3, 95% CI=1.8-2.8) were higher in children with congenital anomalies compared to children without.Interpretation: The proportion of children with major congenital anomalies in the BCPR (11%) was lower than that identified in higher-income countries. This may be because of differences in how congenital anomalies are diagnosed as well as the impact of survival bias. In Bangladesh, children with CP and major congenital anomalies are more likely to have severe functional motor limitations and associated comorbidities.What This Paper Adds: Eleven per cent of children with cerebral palsy (CP) in Bangladesh had major congenital anomalies. Neurological and musculoskeletal congenital anomalies were the most common. Severe functional motor limitations and associated comorbidities were more common in children presenting with CP and major congenital anomalies. [ABSTRACT FROM AUTHOR]

Aim: To assess the responsiveness, concurrent validity, and feasibility of the Dyskinesia Impairment Scale (DIS) in non-ambulatory patients with dyskinetic cerebral palsy (CP).Method: The study is a secondary analysis of data collected in the IDYS trial, a randomized controlled trial on the effects of intrathecal baclofen (ITB). The DIS and Barry-Albright Dystonia Scale (BADS) were conducted at baseline and after 3 months of ITB or placebo treatment. Responsiveness was assessed by comparing the effect sizes and correlation of change after treatment between the DIS and BADS. Concurrent validity was evaluated by assessing the correlations between scales. Feasibility was evaluated for each DIS item by the number of participants who successfully accomplished the item.Results: Thirty-three non-ambulatory patients (9 females, 24 males) with dyskinetic CP (ITB-treated: n=17, mean [SD] age: 14y 1mo [4y 1mo]; placebo-treated: n=16, mean [SD] age: 14y 7mo [4y]) were included in the study. The effect sizes for BADS and DIS were similar in The ITB-treated group (-0.29 and -0.22 respectively). Changes after treatment on the DIS dystonia subscale correlated with changes on the BADS (r=0.64; p<0.001). The DIS dystonia subscale and BADS correlated at baseline and follow-up (r=0.78; p<0.001 and r=0.79; p<0.001). Not all DIS activity items could be performed in this sample of patients.Interpretation: For non-ambulatory patients with dyskinetic CP, the responsiveness of the DIS equalled the responsiveness of BADS. Concurrent validity was adequate. Feasibility for activity items was restricted in patients with severe dyskinetic CP.What This Paper Adds: The Dyskinesia Impairment Scale (DIS) and Barry-Albright Dystonia Scale showed similar responsiveness in non-ambulatory patients with dyskinetic cerebral palsy (CP). No floor or ceiling effect was observed for DIS in non-ambulatory participants. The concurrent validity of DIS was adequate in non-ambulatory participants. Patients with dyskinetic CP in Gross Motor Function Classification System levels IV and V could not perform all DIS activity items. [ABSTRACT FROM AUTHOR]

Aim: To characterize fatigue in children with hemiparesis with perinatal stroke and explore associations with measures of motor performance and corticospinal excitability.Method: Forty-five children (16 females, 29 males), aged 6 to 18 years (mean [SD] 12y [4]), with magnetic resonance imaging-confirmed perinatal stroke participated. Associations between fatigue (Pediatric Quality of Life Inventory Version 3.0 cerebral palsy module fatigue subscale), motor performance (Assisting Hand Assessment [AHA], Box and Blocks Test, grip strength), and excitability of corticospinal projections to both hands were examined using ranked tests of correlation, robust regression, and the Mann-Whitney U test.Results: Nearly half of the participants (n=21) reported experiencing fatigue in the previous month. Function in the less affected hand (Box and Blocks Test, grip strength) was correlated with fatigue scores. Participants with preserved ipsilateral projections to the more affected hand had less fatigue, and scores correlated with the excitability of these projections. Fatigue scores were not associated with age, sex, or AHA score.Interpretation: Fatigue is common in children with hemiparesis with perinatal stroke and is associated with motor performance and the presence and excitability of ipsilateral corticospinal projections from the contralesional hemisphere to the more affected hand.What This Paper Adds: Fatigue is common in children with hemiparesis with perinatal stroke. Fatigue was associated with motor performance and strength in the less affected, but not the more affected, hand. Fatigue was associated with the presence and excitability of ipsilateral corticospinal projections from the contralesional hemisphere. [ABSTRACT FROM AUTHOR]

Aim: To determine the mortality rate, immediate cause of death (CoD), and predictors of death in children with cerebral palsy (CP) in rural Bangladesh.Method: We carried out a prospective population-based surveillance study of children with CP aged 0 to 18 years registered with the Bangladesh Cerebral Palsy Register (BCPR) between January 2015 and December 2016, with subsequent follow-up until December 2017. Verbal autopsy was applied to assign immediate CoD. Crude mortality rates, hazard ratios of death, and survival probabilities were estimated.Results: Twenty-nine of the 678 children in the BCPR died during the study period, resulting in a crude mortality rate of 19.5 per 1000 person-years of observation (total follow-up duration 1486.8 person-years; mean 2y [standard deviation 6mo]). The leading immediate CoD was meningitis (n=9) and pneumonia (n=8). Survival probability and hazard ratio of death was significantly associated with age, Gross Motor Functional Classification System level, and associated impairments. Severe underweight and/or severe stunting was significantly overrepresented among deceased children than others in the cohort (p<0.05) when compared with the World Health Organization reference population.Interpretation: The majority of deaths were due to potentially preventable causes. The life expectancy of these children could have been extended by ensuring primary healthcare and nutritional supplementation.What This Paper Adds: Mortality rate in children with cerebral palsy (CP) in rural Bangladesh is 19.5 per 1000 person-years. The majority of children with CP died from potentially preventable and treatable conditions. Motor severity, associated impairments, and malnutrition make children with CP vulnerable to premature death in rural Bangladesh. [ABSTRACT FROM AUTHOR]

It has been a privilege to publish the original Japanese version of award-winning author Naoki Higashida's perspective on quality of life in autism, and an anonymous Finnish author's experience of fetal alcohol spectrum disorder. In 2022, we have updated the journal layout, to both improve readers' experience (including those with visuoperceptual impairment) and remain up to date with publication efficiency standards. For example, the stability and value of the Gross Motor Function Classification System, designed 25 years ago, and other more recent functional classification systems for cerebral palsy (CP) have been further studied.
