Surgical treatment options for spasticity in children and adolescents with hereditary spastic paraplegia.

PURPOSE: To provide an overview of outcome and complications of selective dorsal rhizotomy (SDR) and intrathecal baclofen pump implantation (ITB) for spasticity treatment in children with hereditary spastic paraplegia (HSP). METHODS: Retrospective study including children with HSP and SDR or ITB. Gross motor function measure (GMFM-66) scores and level of spasticity were assessed. RESULTS: Ten patients were included (most had mutations in ATL1 (n = 4) or SPAST (n = 3) genes). Four walked without and two with walking aids, four were non-walking children. Six patients underwent SDR, three patients ITB, and one both. Mean age at surgery was 8.9 ± 4.5 years with a mean follow-up of 3.4 ± 2.2 years. Five of the SDR patients were walking. Postoperatively spasticity in the legs was reduced in all patients. The change in GMFM-66 score was + 8.0 (0-19.7 min-max). The three ITB patients treated (SPAST (n = 2) and PNPLA6 (n = 1) gene mutation) were children with a progressive disease course. No complications of surgery occurred. CONCLUSIONS: SDR is a feasible treatment option in carefully selected children with HSP, especially in walking patients. The majority of patients benefit with respect to gross motor function, complication risk is low. ITB was used in children with severe and progressive disease.

Parental Beliefs About the Motor Development of Dutch Infants Born Very Preterm: A Cohort Study.

PURPOSE: To explore the influence of preterm birth on parental beliefs about gross motor development and parents' supportive role in infants' motor development. METHODS: Prospective cohort study: Parents of infants born very preterm (VPT) (gestation ≤32 weeks, birth weight <1500 g, without perinatal complications) and parents of healthy infants born full-term (FT) completed the Parental Beliefs on Motor Development questionnaire. RESULTS: Questionnaires from 37 parents of infants born VPT, aged 3.5 to 7.5 months (corrected), and 110 parents of infants born FT, aged 3.5 months, were analyzed. Parents of infants born VPT believed stimulating motor development to be more important than parents of infants born FT (F = 5.22; P = .024; ηp2 = 0.035). Most parents of infants born VPT (82.4%) and FT (85.2%) acknowledged their role in supporting motor development. More parents of infants born VPT (41.2% vs 12.0%) believed they should follow their infant's natural developmental pace. CONCLUSION: Knowledge of parental beliefs and parents' supporting role in motor development is relevant for tailoring pediatric physiotherapists' interventions with families.

Physiological Response to the 6-Minute Frame Running Test in Children and Adults With Cerebral Palsy.

PURPOSE: To determine the physiological response and association to peak oxygen uptake of the 6-minute Frame Running test (6-MFRT) in persons with cerebral palsy (CP). METHODS: Twenty-four participants with CP, Gross Motor Function Classification System II/III/IV, performed the 6-MFRT. Distance, peak heart rate (HR peak ), peak respiratory exchange ratio (RER peak ), and peak oxygen uptake ( O 2peak ) were measured. RESULTS: HR peak ranged from 146 to 201 beats per minute, RER peak from 0.94 to 1.49, 6-MFRT distance from 179 to 1220 m and O 2peak from 0.62 to 2.18 L/min. HR peak was achieved in 63%, RER peak in 71%. A strong correlation was observed between 6-MFRT and O 2peak . CONCLUSIONS: The 6-MFRT represented a (near) maximum effort for 75% of the participants and the 6-MFRT can be used to estimate oxygen consumption on an individual basis.

Mental health monitoring in parents after very preterm birth.

AIM: To evaluate parental mental health monitoring during follow-up care for very preterm (VPT) infants, describe symptoms of anxiety and depression and risk factors for mothers and fathers at 1 and 12 months of corrected age. METHODS: Parents completed the Hospital Anxiety and Depression Scale (HADS). Psychological symptoms and risk factors were analysed within and between mothers and fathers. RESULTS: In 4 years, the monitoring reached 1260 (48%) families. Of these, 693 mothers and 340 fathers (300 couples) completed the HADS twice. At 1 month, 22% and 15% of the mothers and 10% and 9% of the fathers, respectively, reported elevated symptoms of anxiety and depression. At 12 months, these rates were significantly reduced to 14% and 9% for mothers and 5% and 4% for fathers respectively. Within couples, anxiety and depression were positively associated. At 12 months, in 20% of the couples, one or both parents reported elevated symptoms. Risk factors were length of hospital stay, migration background, educational level and employment status. CONCLUSION: The mental health of parents of VPT infants improved, but elevated symptoms were still observed in 17% of included families after one year. Acknowledging and remediating parental mental health remain essential during follow-up care.

Early-life growth of preterm infants and its impact on neurodevelopment.

BACKGROUND: Increasing numbers of preterm-born children survive nowadays, and improving long-term health and neurodevelopment is becoming more important. Early-life growth has been linked to neurodevelopmental outcomes. We aimed to study whether this association has changed with time. METHODS: We studied two cohorts of preterm-born children (gestational age ≤32 weeks and/or birth weight ≤1500 g) from 1983 (n = 708) and 2003-2006 (n = 138), respectively. We distinguished four early-life growth patterns at 3 months corrected age: appropriate for gestational age (AGA) with or without growth restriction (AGA GR+/AGA GR-), and small for gestational age (SGA) with or without catch-up growth (SGA CUG+/SGA CUG-). Intelligence quotient (IQ), neuromotor function, and behavior were assessed at ages 19 and 8 years, respectively, for the cohorts. RESULTS: In the 2003-2006 cohort, less children had early-life GR. In both cohorts, SGA CUG- subjects had unfavorable growth trajectories and neurodevelopmental outcomes (IQ ß -6.5, 95% confidence interval (CI) -9.8; -3.2, P < 0.001; neuromotor score ß -1.9%, 95% CI -3.2; -0.6, P = 0.005), while SGA CUG+ subjects were comparable to adequately grown subjects. CONCLUSION: Although the incidence of adverse growth patterns decreased between the cohorts, possibly indicating improvements in care over time, the impact of these growth patterns on neurodevelopmental outcomes was not significantly different. Achieving adequate early-life growth may be crucial for improving neurodevelopmental outcomes, especially for preterms born SGA.

Factors Associated With Long-Term Improvement of Gait After Selective Dorsal Rhizotomy.

OBJECTIVE: To identify factors associated with long-term improvement in gait in children after selective dorsal rhizotomy (SDR). DESIGN: Retrospective cohort study. SETTING: University medical center. PARTICIPANTS: Children (N=36) (age 4-13y) with spastic diplegia of Gross Motor Function Classification System (GMFCS) level I (n=14), II (n=15), and III (n=7) were included retrospectively from the database of our hospital. Children underwent SDR between January 1999 and May 2011. Patients were included if they received clinical gait analysis before and 5 years post-SDR, age >4 years at time of SDR and if brain magnetic resonance imaging (MRI) scan was available. INTERVENTION: Selective dorsal rhizotomy. MAIN OUTCOME MEASURES: Overall gait quality was assessed with Edinburgh visual gait score (EVGS), before and 5 years after SDR. In addition, knee and ankle angles at initial contact and midstance were evaluated. To identify predictors for gait improvement, several factors were evaluated including functional mobility level GMFCS, presence of white matter abnormalities on brain MRI, and selective motor control during gait (synergy analysis). RESULTS: Overall gait quality improved after SDR, with a large variation between patients. Multiple linear regression analysis revealed that worse score on EVGS and better GMFCS were independently related to gait improvement. Gait improved more in children with GMFCS I and II compared to III. No differences were observed between children with or without white matter abnormalities on brain MRI. Selective motor control during gait was predictive for improvement of knee angle at initial contact and midstance, but not for EVGS. CONCLUSION: Functional mobility level and baseline gait quality are both important factors to predict gait outcomes after SDR. If candidates are well selected, SDR can be a successful intervention to improve gait both in children with brain MRI abnormalities as well as other causes of spastic diplegia.

Risk Factors for Dystonia after Selective Dorsal Rhizotomy in Nonwalking Children and Adolescents with Bilateral Spasticity.

We recently showed a beneficial effect of selective dorsal rhizotomy (SDR) on daily care and comfort in nonwalking children with severe bilateral spasticity. However, despite careful selection, some patients showed dystonia after the intervention, in which cases caregivers tended to be less satisfied with the result.The aim of this study is to identify risk factors for dystonia after SDR in children and adolescents with severe bilateral spasticity (GMFCS levels IV/V).Clinical and MRI risk factors for dystonia after SDR were studied in our cohort of 24 patients. Patients with clinical evidence of dystonia and brain MRI showing basal ganglia abnormalities were excluded for SDR.Nine of 24 patients (38%) showed some degree of dystonia after SDR. There was a significant association between the cause of spasticity and dystonia after SDR; in six (67%) patients with a congenital disorder, dystonia was present versus three (20%) with an acquired disorder (Chi-squared test: C(1) = 5.23, p = 0.02).This study allows more optimal selection of patients that may benefit from SDR. Patients with an acquired cause of spasticity, when selected carefully on clinical examination and MRI, rarely show dystonia after SDR. However, patients with an underlying congenital disorder have a considerable risk of dystonia after SDR.

Feasibility of a Preventive Parenting Intervention for Very Preterm Children at 18 Months Corrected Age: A Randomized Pilot Trial.

OBJECTIVE: To evaluate the feasibility and potential efficacy of an age-appropriate additional parenting intervention for very preterm born toddlers. STUDY DESIGN: In a randomized controlled pilot study, 60 of 94 eligible very preterm born children who had received a responsive parenting intervention in their first year were randomized to usual care or the additional intervention, consisting of 4-6 home visits between 18 and 22 months' corrected gestational age (CA). Parents were supported to responsively interact during increasingly complex daily activities and play. Parental satisfaction with the intervention was evaluated with a questionnaire. At baseline and 24 months CA, parents completed the Infant Toddler Social and Emotional Assessment, the Ages and Stages Questionnaire, and the Dutch Schlichting Lexilist for receptive language. At 24 months CA, motor, and cognitive development was measured by the Bayley Scales of Infant and Toddler Development, Third Edition Dutch version, and parent-child interaction was evaluated by the Emotional Availability Scales. RESULTS: Parental compliance and satisfaction with the intervention was high. Effect sizes (after correction for baseline variables) were small for internalizing and competence behavior, receptive language, and problem solving; medium for cognitive development and parent-child interaction; and large for externalizing and dysregulation behavior and motor development. CONCLUSION: After a postdischarge intervention during the first year, an additional responsive parenting support at toddler-age is feasible and associated with positive outcomes in a broad array of parental and child outcome measures.

Neurodevelopmental outcome during the first year of life in preterm infants after supplementation of a prebiotic mixture in the neonatal period: a follow-up study.

AIM: The study aimed to determine the effect of enteral supplementation of a prebiotic mixture (neutral and acidic oligosaccharides) in the neonatal period on neurodevelopmental outcome in preterm infants with a gestational age of less than 32 weeks and/or birth weight of less than 1,500 g in the first year of life. METHODS: Neurodevelopmental outcome consisted of tone and motility according to Touwen, motor ability according to the Alberta Infant Motor Scale, as well as vision and hearing were evaluated at 0, 3, 6, and 12 months corrected age (CA). To adjust for potential confounders, data were analyzed by multinomial or logistic regression. RESULTS: In total, 93 of 101 infants (92%) participated in the study (prebiotic mixture group [n = 48] and placebo group [n = 45]). Incidence of suspect and abnormal neurodevelopmental outcome and delayed motor ability was not different in the prebiotic mixture and placebo group at 0, 3, 6, and 12 months (CA). Infants with 1 or more neonatal infections or more had a higher incidence of abnormal neurodevelopmental outcome (OR: 20.73; 95% CI: 1.31-328.46; p = 0.03) at 6 months CA. CONCLUSION: Short-term enteral supplementation of a prebiotic mixture in the neonatal period had no effect on neurodevelopmental outcome in preterm infants in the first year of life. However, serious neonatal infections in preterm infants were associated with adverse neurodevelopmental outcome at 6 months, but not at 12 months.

Developmental trajectories of receptive and expressive communication in children and young adults with cerebral palsy.

AIM: The aim of this study was to determine the developmental trajectories of expressive (speech) and receptive (spoken and written language) communication by type of motor disorder and intellectual disability in individuals with cerebral palsy (CP). METHOD: The development of 418 participants (261 males, 157 females; mean age 9y 6mo [SD 6y 2mo], range 1-24y; Gross Motor Function Classification System (GMFCS) level I [n=206], II [n=57], III [n=59], IV [n=54], V [n=42]) was followed for 2 to 4 years in a longitudinal study. Communication performance was measured using the Vineland Adaptive Behavior Scales. The type of motor disorder was differentiated by type of CP as unilateral spastic (USCP, n=161), bilateral spastic (BSCP, n=202), and non-spastic (NSCP, n=55), while intellectual disability was determined by IQ or school type (regular or special). A multilevel analysis was then used to model the developmental trajectories. RESULTS: The most favourable development of expressive communication was seen in USCP (vs BSCP ß [SE]-2.74 [1.06], NSCP ß [SE]-2.67 [1.44]). The difference between the development trajectory levels of children with and without intellectual disability was smaller for children with USCP than for those with BSCP and NSCP. For receptive communication, the most favourable development was found for all children with USCP and for BSCP or NSCP without intellectual disability (vs intellectual disability ß [SE]-4.00 [1.16]). Development of written language was most favourable for children without intellectual disability (vs intellectual disability ß [SE]-23.11 [2.85]). INTERPRETATION: The development of expressive communication was found to be most closely related to type of motor disorder, whereas the development of receptive communication was found to be most closely related to intellectual disability.

How do changes in motor capacity, motor capability, and motor performance relate in children and adolescents with cerebral palsy?

OBJECTIVE: To investigate the relations between changes in motor capacity (can do, in standardized environment), motor capability (can do, in daily environment), and motor performance (does do, in daily environment) among children with cerebral palsy (CP). DESIGN: Prospective longitudinal study. After baseline measurements (at the age of 18 mo, 30 mo, 5 y, 7 y, 9 y, 11 y, or 13 y), 2-year follow-up measurements were performed. Change scores were calculated, and Pearson correlations were used for change score relations. SETTING: Outpatient clinic. PARTICIPANTS: Toddlers, school-age children, and adolescents with CP (N=321; 200 boys, 121 girls). Levels of severity according to the Gross Motor Function Classification System included level I (42%), level II (15%), level III (17%), level IV (13%), and level V (13%). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Change in motor capacity was assessed with the Gross Motor Function Measure-66. Changes in motor capability and motor performance were assessed with the Pediatric Evaluation of Disability Inventory using the Functional Skills Scale and Caregiver Assistance Scale, respectively. RESULTS: Within the total group, change score correlations were moderate (.52-.67) and significant (P<.001). For age groups, correlations were significantly higher in toddlers than school-age children and adolescents. For severity levels, correlations were significantly higher in children at level III than level I, IV, and V. CONCLUSIONS: Results imply that change in motor capacity does not automatically translate to change in motor capability and change in motor capability does not automatically translate to change in motor performance. Results also show different relations for clinically relevant subgroups. These are important insights for clinical practice because they can guide evidence-based interventions with a focus on activities.

Long-term effect of selective dorsal rhizotomy on gross motor function in ambulant children with spastic bilateral cerebral palsy, compared with reference centiles.

AIM: The aim of this study was to evaluate the long-term effect of selective dorsal rhizotomy (SDR) on the gross motor function of ambulant children with spastic bilateral cerebral palsy (CP), compared with reference centiles. METHOD: The study used a prospective cohort design and participants comprised 29 children classified using the Gross Motor Function Classification System (GMFCS) in level I (n=7), II (n=4), or III (n=18; 18 males, 11 females; median age at time of surgery 6 y 4 mo; range 2 y 10 mo-12 y 1 mo), who were examined 5 years and 10 years after SDR. We used individual centiles based on Gross Motor Function Measure (GMFM-66) scores and age, corresponding to the GMFCS levels. Individual improvement or deterioration was defined as a change of more than 20 centiles. Side effects experienced and additional treatment received after SDR were also recorded. RESULTS: Five years after SDR, 10 out of 28 children showed improvement, and 10 years after SDR 6 out of 20 children had improved. Spinal side effects were noted in two children and hip subluxation in three. Additional treatments included subtalar arthrodesis (n=13), endorotational osteotomy of the tibia (n=5), and botulinum toxin treatment (n=13). INTERPRETATION: None of the children showed deterioration of gross motor function based on centile ranking. Five and 10 years after SDR, gross motor function in some children had improved more than would have been expected according to the reference centiles. This suggests, taking the limitations of this study into account, that the applied criteria for selection were adequate. However, the children still required additional treatment after SDR.

The Impact of Frame Running on Quality of Life in Young Athletes With Mobility Limitations.

Purpose: The para-athletic sport Frame Running is developed for persons with neurological impairments causing severe limitations of walking ability. Participating in sports can contribute to a better quality of life (QoL). It is unknown if participation in Frame Running contributes to QoL in children with mobility limitations. This study aims to explore the changes in QoL in children and youth who started Frame Running. Materials and Methods: We conducted a cross-sectional study amongst young Frame Running athletes with mobility limitations due to various underlying causes, aged 6-19 years, who are members of one of the Frame Running groups in the Netherlands. For 62 athletes, parents completed the Psychosocial Impact of Assistive Devices Scale (PIADS) questionnaire (subscales: competence, adaptability, and self-esteem). For six athletes, parents were interviewed to obtain more in-depth insight in the perceived changes in the QoL of their children. Results: Parents (of 58% boys, mean age 12 years 4 months; SD 3 years 3 months; 52% supported walkers) reported a significant positive change on all three subscales of the PIADS questionnaire since their children started Frame Running. Most change was experienced in the items performance, the ability to participate, happiness and self-confidence. Quotes of the parents who were interviewed elucidated these changes. Conclusion: Frame Running increased QoL in young athletes with a mobility limitation. Frame Running may therefore be advised for these children and youth to improve QoL.

Athlete-Perceived Impact of Frame Running on Physical Fitness, Functional Mobility and Psychosocial Outcomes.

OBJECTIVE: Frame Running (RaceRunning) allows people with moderate-to-severe mobility impairments to participate in physical activity using a 3-wheeled frame with a saddle and handlebars. The aim of this study was to investigate athlete-perceived impact of Frame Running on aspects of physical fitness, functional mobility and psychosocial outcomes. DESIGN: Survey. PARTICIPANTS: Frame Running athletes aged 5 years and over. METHODS: A survey was distributed to athletes through their club or sports organization. RESULTS: The survey was completed by 115 athletes (53 females). Median age was 17 years (range 5-62 years) and 64 (57%) used a wheelchair or walker for distances over 50 m. Many felt that Frame Running stretched their muscles (n = 93, 87%) and increased their self-confidence (n = 63, 93%). Four (4%) reported extreme fatigue or sore muscles after training (n = 17, 15%). Of the 110 athletes who had been participating in Frame Running for over 3 months, 46 (47%) reported being less out of breath during mobility tasks and 66 (66%) felt they had improved their functional mobility. However, 7 (7%) reported increased muscle tightness and 4 (4%) reported a Frame Running-related injury lasting more than 4 weeks. CONCLUSION: Frame Running is a safe physical activity with athlete-perceived benefits on physical fitness, functional mobility and psychosocial outcomes.

Outcome at 4.5 years of children born after expectant management of early-onset hypertensive disorders of pregnancy.

OBJECTIVE: The objective of the study was to describe neurodevelopmental outcome at the age of 4.5 years in 216 children, born after expectant management of severe early-onset hypertensive complications of pregnancy. STUDY DESIGN: This was a prospective follow-up study until age 4.5 years from maternal admission onward. Developmental outcome measurements included child intelligence quotient and behavioral, motor, and neurological outcome. Abnormal composite outcome (perinatal mortality or abnormal developmental outcome) was studied in relation to gestational age (GA), birthweight (BW), and perinatal variables. RESULTS: Fetal and neonatal mortality was 9% and 8%, respectively. Of the 178 survivors, 149 (84%) were seen for follow-up. Mean GA was 31.4 weeks and 90% were born growth restricted. Abnormal developmental outcome occurred in 20% and abnormal composite outcome in 37%. CONCLUSION: Perinatal mortality or abnormal child development occurs in one third of pregnancies with early-onset and severe hypertensive complications and is highest in the lowest GA and BW ranges.

Prognostic value of brain abnormalities for cognitive functioning in cerebral palsy: A prospective cohort study.

INTRODUCTION: Brain abnormalities in cerebral palsy (CP) are known to relate to motor outcome; however, their association with cognitive functioning is less clear. AIM OF THE STUDY: 1) To investigate the prognostic value of brain abnormalities for cognitive functioning; 2) To explore the added value of prognostic variables across ICF domains: motor function, epilepsy, gestational age, birthweight and educational level of the parents. METHODS: We retrospectively analyzed brain MRI scans of 75 children with CP (GMFCS level I-V, 36% born preterm), as part of a longitudinal study. MRI classification: qualitative classification of brain abnormality pattern and semi-quantitative grading of the extent of damage. Cognitive functioning, measured as non-verbal intelligent quotient (IQ), was dichotomized into 'impaired cognition' (IQ ≤ 70) and 'normal' (IQ > 70). Multivariable logistic regression produced odds ratios (OR) with 95% confidence interval (C.I.) of risk factors for impaired cognition. RESULTS: Overall, 27% of the tested participants had a non-verbal IQ below 70 and 36% of the participants was classified as 'having impaired cognition'. At a young age, a higher degree of white matter damage (OR 1.6, 95% C.I. 0.97-2.67) and a more severe GMFCS level (OR 3.2, 95% C.I. 1.70-5.98) are risk factors for impaired cognition at school-age (4-7 years of age). This model correctly predicts 89% of the cases. Brain damage alone predicts the presence of impaired cognition in 71% of the cases. INTERPRETATION: Brain MRI characteristics and GMFCS level at a young age can each help identify children with CP at risk for impaired cognition at school age and together have a strong predictive value.

Relationship between gross motor capacity and daily-life mobility in children with cerebral palsy.

AIM: The aim of this study was to examine the relationship between gross motor capacity and daily-life mobility in children with cerebral palsy (CP) and to explore the moderation of this relationship by the severity of CP. METHOD: Cross-sectional analysis in a cohort study with a clinic-based sample of children with CP (n=116; 76 males, 40 females; mean age 6 y 3 mo, SD 12 mo, range 4 y 8 mo-7 y 7 mo) was performed. Gross motor capacity was assessed by the Gross Motor Function Measure (GMFM-66). Daily-life mobility was assessed using the Pediatric Evaluation of Disability Inventory (PEDI): Functional Skills Scale (FSS mobility) and Caregiver Assistance Scale (CAS mobility). Severity of CP was classified by the Gross Motor Function Classification System (48% level I, 17% level II, 15% level III, 8% level IV, 12% level V), type of motor impairment (85% spastic, 12% dyskinetic, 3% ataxic), and limb distribution (36% unilateral, 49% bilateral spastic). RESULTS: Scores on the GMFM-66 explained 90% and 84% respectively, of the variance of scores on PEDI-FSS mobility and PEDI-CAS mobility. Limb distribution moderated the relationship between scores on the GMFM-66 and the PEDI-FSS mobility, revealing a weaker relationship in children with unilateral spastic CP (24% explained variance) than in children with bilateral spastic CP (91% explained variance). INTERPRETATION: In children aged 4 to 7 years with unilateral spastic CP, dissociation between gross motor capacity and daily-life mobility can be observed, just as in typically developing peers.

Motor testing at 1 year improves the prediction of motor and mental outcome at 2 years after perinatal hypoxic-ischaemic encephalopathy.

AIM: To investigate the predictive value of motor testing at 1 year for motor and mental outcome at 2 years after perinatal hypoxic-ischaemic encephalopathy (HIE) in term neonates. METHOD: Motor and mental outcome at 2 years was assessed with the Bayley Scales of Infant Development, 2nd edition (BSID-II) in 32 surviving children (20 males, 12 females; mean gestational age 40.2 wk, SD 1.4; mean birthweight 3217g, SD 435) participating in a prospective cohort study of HIE. The predictive value of three motor tests (Alberta Infant Motor Scale [AIMS], BSID-II, and the Neurological Optimality Score [NOS]) at 1 year was analysed, in addition to predictions based on neonatal Sarnat staging and magnetic resonance imaging (MRI). Poor motor test results were defined as an AIMS z-score of <-2, a psychomotor developmental index of the BSID-II of <70, or a NOS of <26. Poor motor and poor mental outcome at 2 years was defined as a psychomotor developmental index or mental developmental index of the BSID-II of <70. RESULTS: Twelve children, all with Sarnat grade II, had a poor motor outcome and 12 children, of whom one had Sarnat grade I, had a poor mental outcome at 2 years. Nine children had cerebral palsy, of whom five had quadriplegia, three had dyskinesia, and one had hemiplegia. Poor motor tests at 1 year increased the probability of a poor motor outcome from 71% (range 92 to 100%), and a poor mental outcome from 59% (range 77 to 100%) in children with Sarnat grade II and abnormal MRI, assessed with the AIMS and BSID-II or NOS respectively. INTERPRETATION: Additional motor testing at 1 year improves the prediction of motor and mental outcome at 2 years in children with Sarnat grade II and abnormal MRI.
