This study aimed to determine whether motor function and performance is better enhanced by intensive physiotherapy or collaborative goal-setting in children with cerebral palsy (CP). Participants were a convenience sample of 56 children with bilateral CP classified at level III or below on the Gross Motor Function Classification System (GMFCS), aged between 3 and 12 years. A 2X2 factorial design was used to compare the effects of routine amounts of physiotherapy with intensive amounts, and to compare the use of generalized aims set by the child's physiotherapist with the use of specific, measurable goals negotiated by the child's physiotherapist with each child, carer, and teacher. Following the six-month treatment period there was a further six-month period of observation. Changes in motor function and performance were assessed by a masked assessor using the Gross Motor Function Measure (GMFM) and the Gross Motor Performance Measure (GMPM) at three-month intervals. There was no statistically significant difference in the scores achieved between intensive and routine amounts of therapy or between aim-directed and goal-directed therapy in either function or performance. Inclusion of additional covariates of age and severity levels showed a trend towards a statistically significant difference in children receiving intensive therapy during the treatment period. This advantage declined over the subsequent six months during which therapy had reverted to its usual amount. Differences in goal-setting procedures did not produce any detectable effect on the acquisition of gross motor function or performance.

The aims of this study were to determine the relation between gait kinematics (center of mass excursions) and measures of oxygen consumption and oxygen cost. Fourteen independent ambulating children with myelomeningocele (nine females, five males; mean age 8 years 7 months) and thirteen children with no history of neuromuscular disorder were evaluated. At their comfortable walking speed all patients exhibited oxygen cost and oxygen consumption values that exceeded the normal level by more than 1 SD. Pelvic obliquity demonstrated the strongest relation with oxygen cost which suggests that ultimately hip abductor strength may play a key role in energy demands during gait. Despite the exaggerated pelvic kinematics, vertical and horizontal center of mass excursions of the trunk and whole-body during the gait cycle were not significantly greater than normal (p>0.05). Decreased self-selected walking velocity at which many of these children consider comfortable and stable may be predicated on an optimal center of mass movement that approximates the magnitude observed in normal gait. The slower walking velocity decreases walking efficiency. Conversely, the increased center of mass movement that would accompany a faster gait would probably impose intolerable oxygen consumption levels. Strengthening programs that focus on the gluteus medius and maximus to decrease compensatory trunk and pelvic motions, allowing the patients to adopt a faster gait without exacerbating kinematic and center of mass motions and which enabled more efficient walking hold promise for these patients.

Twenty healthy preterm infants (gestational age 26 to 33 weeks, postmenstrual age [PMA] 32.1 to 39.6 weeks, postnatal age [PNA] 2.0 to 11.6 weeks) were studied weekly from initiation of bottle feeding until discharge, with simultaneous digital recordings of pharyngeal and nipple (teat) pressure and nasal thermistor and thoracic strain gauge readings. The percentage of sucks aggregated into ‘runs’ (defined as [ges ] 3 sucks with [les ] 2 seconds between suck peaks) increased over time and correlated significantly with PMA (r=0.601, p<0.001). The length of the sucking-runs also correlated significantly with PMA (r=0.613, p<0.001). The stability of sucking rhythm, defined as a function of the mean/SD of the suck interval, was also directly correlated with increasing PMA (r=0.503, p=0.002), as was increasing suck rate (r=0.379, p<0.03). None of these measures was correlated with PNA. Similarly, increasing PMA, but not PNA, correlated with a higher percentage of swallows in runs (r=0.364, p<0.03). Stability of swallow rhythm did not change significantly from 32 to 40 weeks' PMA. In low-risk preterm infants, increasing PMA is correlated with a faster and more stable sucking rhythm and with increasing organization into longer suck and swallow runs. Stable swallow rhythm appears to be established earlier than suck rhythm. The fact that PMA is a better predictor than PNA of these patterns lends support to the concept that these patterns are innate rather than learned behaviors. Quantitative assessment of the stability of suck and swallow rhythms in preterm infants may allow prediction of subsequent feeding dysfunction as well as more general underlying neurological impairment. Knowledge of the normal ontogeny of the rhythms of suck and swallow may also enable us to differentiate immature (but normal) feeding patterns in preterm infants from dysmature (abnormal) patterns, allowing more appropriate intervention measures.

To understand how the ‘caregiving context’ could affect responses to procedural pain, the authors sought to determine whether (1) the combined effects of sweet taste and holding (caregiving contact) were greater than the effects of either alone, (2) any combined effects were additive or interactive, and (3) the interventions had similar effects on behavioral (crying and facial activity) and physiological (heart rate, vagal tone) responses to the heel-stick procedure in newborn infants in a randomized two-factorial intervention trial. Eighty-five normally developing newborn infants were studied with a mean gestational age of 39.4 weeks on the 2nd or 3rd day of life. Infants were randomized in blocks of eight to receive (1) no holding and water taste (control participants), (2) no holding and sucrose taste (sucrose group), (3) holding and water taste (holding group), or (4) holding and sucrose taste (holding and sucrose group). Crying was reduced significantly by taste and holding, and the interventions combined additively. Facial activity was only significantly reduced by holding. For physiological measures, the interventions interacted with each other and preintervention levels to reduce heart rate and lower vagal tone more during the procedure in infants in whom heart rate and vagal tone were higher before intervention. Consequently, sweet taste and holding interventions combined in complex ways when acting on different behavioral and physiological response systems to modify stressful pain experiences. The results suggest that providing a caregiving context when painful procedures are performed may be a simple and practical method of reducing pain experience in infants, and that no one measure captures these effects.

In order to identify the prevalence and severity of feeding problems in children with Silver-Russell syndrome(SRS) the feeding difficulties of 32 children with SRS and 32 age- and sex-matched control children were assessed using the Feeding Assessment Questionnaire (Harris and Booth 1992). Children's ages ranged from 2 to 11 years, with 19 male and 13 female pairs. In a subset of matched pairs, parent–child interaction at mealtimes was examined using video recording; food intake was also assessed over a 3-day period using weighed food diaries. Children with SRS experienced significantly more feeding problems than children without growth disorders. Common feeding problems for children with SRS were poor appetite, fussiness, slow feeding, and problems associated with oral-motor dysfunction. Feeding problems did not significantly affect intake of kilocalories, protein, fat, or carbohydrates. Mealtime interaction between children with SRS and their parents was significantly more negative than interactions between control-group children and their parents. The focus of intervention packages in SRS should be to reduce negative parent–child interactions and reduce parental anxiety about feeding, growth, and weight.

The International Headache Society (IHS) classification system (1988) was developed primarily for headache disorders in adults and its validity for paediatric age is currently under discussion; in 1995 Seshia et al. proposed a revision of the criteria for migraine without aura to make diagnostic criteria more applicable to children. The purposes of the current study were to: (1) compare the IHS classification with the Seshia proposal, (2) compare the children affected by migraine without aura (MO) with the children affected by tension headache (TH) as defined by Seshia, for characteristics which are not included in the classification. The patients are a series of 320 children (mean age 9.9, SD 2.6 years; 144 males, 176 females) with recurrent or chronic headaches referred to a headache clinic in Milan, Italy. Using the Seshia criteria instead of the IHS criteria a higher number of children were included in the MO category: bilateral pain and family history of migraine were the most important factors which allowed a shift of children into this category. However, with the Seshia classification there was no reduction in the number of unclassifiable children. The reason why some children could not be classified was a short duration of attacks; the majority of unclassifiable children were 6 years old or less. No relevant difference was found between children with MO and children with TH for the following variables: occurrence of attacks in the afternoon or evening after school, reduction of attacks during school holidays, full-time schooling, after-school activities on school days, disordered daily life. On the contrary children with MO when compared with those with TH showed a higher number of precipitating factors and for the following factors a significant difference was found: exposure to TV or a computer, sleep deficiency, and strong emotions. Furthermore, children with MO showed a greater severity of attacks.

Learning disability and cerebral palsy are often related to factors present before birth. We report three patients (two with schizencephaly, one with unilateral cerebellar agenesis) in whom the timing of an insult to the foetus was known. In the first case, the mother had a trauma at 16 weeks of pregnancy and schizencephaly was discovered in the male infant associated with a left hemiplegia. In the second child, amniocentesis performed at 16 weeks into pregnancy may have been responsible for the same cortical anomaly. In the third case, sequential foetal echographies clearly demonstrated that an apparent unilateral cerebellar agenesis was related to an haemorrhagic event secondary to cerebellar trauma that occurred at 19 weeks of pregnancy. It is suggested that these brain malformations are related to an ischemic mechanism or a traumatic event in foetal life.

Cortical visual impairment (CVI) is the leading cause of bilateral visual impairment in children in Western countries. This finding reflects better methods for identifying visual impairment due to CNS injury and also advances in perinatal care, which have increased the survival rate of children with neurological morbidity. This review will describe advances in the diagnosis and management of CVI. Central to our discussion is a definition of CVI that includes a decrease in visual acuity. New treatment and rehabilitative measures are badly needed for this disorder. We hope to stimulate interest in CVI, a disease that has become a significant public health problem.

Intrauterine growth retardation (IUGR) due to placental dysfunction is a risk factor for an impaired neurodevelopmental outcome. This is the case particularly in growth-retarded foetuses whose conditions in utero are so compromised that they have to be delivered before term. In recent years, neonatal treatment and care have improved markedly, and this has led to increased chances of survival of very immature and extremely low-birthweight infants. The optimal time to deliver IUGR infants remains difficult to assess. There is an obvious need for methods that accurately monitor foetal and neonatal condition, and it is important that the implications of these methods are evaluated for the neurodevelopmental outcomes of these infants. It is vitally important to be able to predict the outcome, whether it is normal or abnormal. A method that covers both aspects is the qualitative assessment of spontaneous motility of foetuses and newborn infants.
