The aim of this study was to test the inter- and intraobserver reliability of the Physician Rating Scale (PRS) and the Edinburgh Visual Gait Analysis Interval Testing (GAIT) scale for use in children with cerebral palsy (CP). Both assessment scales are quantitative observational scales, evaluating gait. The study involved 24 patients ages 3 to 10 years (mean age 6.7 years) with an abnormal gait caused by CP. They were all able to walk independently with or without walking aids. Of the children 15 had spastic diplegia and 9 had spastic hemiplegia. With a minimum time interval of 6 weeks, video recordings of the gait of these 24 patients were scored twice by three independent observers using the PRS and the GAIT scale. The study showed that both the GAIT scale and the PRS had excellent intraobserver reliability but poor interobserver reliability for children with CP. In the total scores of the GAIT scale and the PRS, the three observers showed systematic differences. Consequently, the authors recommend that longitudinal assessments of a patient should be done by one observer only.

This study explored possible neural mechanisms that contribute to improvements in balance control produced by reactive balance training in children with cerebral palsy (CP). Six children with CP (four males, two females; mean age 9y 4mo), two with spastic hemiplegia (Gross Motor Function Classification System [GMFCS] level I) and four with spastic diplegia (GMFCS level II,) were given 5 days of intensive training in reactive balance control (100 perturbations per day on a moveable force platform). Surface electromyography was used to characterize changes in neuromuscular responses pretraining, immediately posttraining, and 1 month posttraining. Training in reactive balance control resulted in improvements in directional specificity of responses (a basic level of response organization) and other spatial/temporal characteristics including: (1) faster activation of muscle contraction after training, allowing children to recover stability faster; (2) emergence of a distal-proximal muscle sequence; and (3) improved ability to modulate the amplitude of muscle activity (increased amplitude of agonist and decreased amplitude of antagonist, reducing coactivation). Each child with spastic hemiplegia or diplegia showed a different combination of factors that contributed to improved performance; the level of change in neural factors depended on the severity of involvement of the child: hemiplegia vs diplegia, and level of involvement within each diagnostic category.

Participation and activity performance (motor and cognitive or behavioural) were examined in 148 children with cerebral palsy (CP; 87 males, 61 females; mean age 9y 8mo, SD 1y 11mo; range 6y 1mo to 13y 7mo), mainstreamed in fully inclusive (n=100) and in self-contained classes (n=48) within general schools in Israel, using the School Function Assessment. Differences in participation within these groups were analyzed in relation to the type of CP (mainly spastic hemiplegia, spastic diplegia, and spastic tetraplegia), the level of impairment according to the Gross Motor Function Classification System (GMFCS; level II 55%, level III 37%, and level IV 8%), and additional neuroimpairments. Univariate analyses of variance revealed significant differences in levels of participation and levels of activity performance between different types of CP and GMFCS levels. With regard to additional neuroimpairments, significant differences in participation were found for fully included children with speech and language impairments and those with learning disability within the self-contained group. Physical activity performance partly accounted for differences in participation between children with different types of CP and different levels of motor impairment. These findings suggest that within the mainstreamed environment, participation and activity performance increase as motor disability and/or additional neuroimpairments (speech and language impairments and learning disability) decrease.

To determine the frequency and predictors of sleep disorders in children with cerebral palsy (CP) we analyzed the responses of 173 parents who had completed the Sleep Disturbance Scale for Children. The study population included 100 males (57.8%) and 73 females (42.2%; mean age 8y 10mo [SD 1y 11mo]; range 6y-11y 11mo). Eighty-three children (48.0%) had spastic diplegia, 59 (34.1%) congenital hemiplegia, 18 (10.4%) spastic quadriplegia, and 13 (7.5%) dystonic/dyskinetic CP. Seventy-three children (42.2%) were in Gross Motor Function Classification System Level I, 33 (19.1%) in Level II, 30 (17.3%) in Level III, 23 (13.3%) in Level IV, and 14 (8.1%) in Level V. Thirty children (17.3%) had epilepsy. A total sleep problem score and six factors indicative of the most common areas of sleep disorder in childhood were obtained. Of the children in our study, 23% had a pathological total sleep score, in comparison with 5% of children in the general population. Difficulty in initiating and maintaining sleep, sleep-wake transition, and sleep breathing disorders were the most frequently identified problems. Active epilepsy was associated with the presence of a sleep disorder (odds ratio [OR]=17.1, 95% confidence interval [CI] 2.5-115.3), as was being the child of a single-parent family (OR=3.9, 95% CI 1.3-11.6). Disorders of initiation and maintenance of sleep were more frequent in children with spastic quadriplegia (OR=12.9, 95% CI 1.9-88.0), those with dyskinetic CP (OR=20.6, 95% CI 3.1-135.0), and those with severe visual impairment (OR=12.5, 95% CI 2.5-63.1). Both medical and environmental factors seem to contribute to the increased frequency of chronic sleep disorders in children with CP.

The incidence of epilepsy in 110 patients with cerebral palsy (the majority with spastic tetraplegia) was 46,4%. Almost half of the patients with spastic tetraplegia (45%) and hemiplegia (52%) had epilepsy. The incidence was lower in patients with spastic diplegia (32%). Half of epilepsy in spastic hemiplegia were partial seizures and the other half consisted of generalized seizures, while generalized tonic-clonic episodes predominated in all other forms of C.P. A high incidence of West syndrome was observed in patients with spastic tetraplegia. Etiological factors of C.P. were perinatal in 75%. 16,65% had neonatal antecedents of convulsions; most of them had spastic tetraplegia (75%) and a significant mental retardation. A low intelligence quotient (I.Q.) was seen in most of the children with epilepsy, and patients with tetraplegia had significantly lower intelligence quotient than other groups.

The purpose of this study is to introduce and describe a newly developed index using foot pressure analysis to quantify the degree of equinus gait in children with cerebral palsy before and after injection with botulinum toxin. Data were captured preinjection and 12 weeks postinjection. Ten children aged 2(1/2) to 6(1/2) years took part (5 boys and 5 girls). Three of them had a diagnosis of spastic diplegia and 7 of congenital hemiplegia. In total, 13 limbs were analyzed. After orientation and segmentation of raw pedobarographic data, we determined a dynamic foot pressure index graded 0 to 100 that quantified the relative degree of heel and forefoot contact during stance. These data were correlated (Pearson correlation) with clinical measurements of dorsiflexion at the ankle (on a slow and fast stretch) and video observation (using the Observational Gait Scale). Pedobarograph data were strongly correlated with both the Observational Gait Scale scores (R = 0.79, P < 0.005) and clinical measurements of dorsiflexion on a fast stretch, which is reflective of spasticity (R = 0.70, P < 0.005). We demonstrated the index's sensitivity in detecting changes in spasticity and good correlation with video observations seems to indicate this technique's potential validity. When manipulated and segmented appropriately, and with the development of a simple ordinal index, we found that foot pressure data provided a useful tool in tracking changes in patients with spastic equinus.

This study examined whether the self-concept of children with cerebral palsy (CP) differed from that of children without impairment. Forty-seven children (24 males, 23 females; mean age 11y 8mo [SD 2y 6mo]) with spastic diplegia or hemiplegia were matched with children without impairment. The level of disability of the children with CP was classified as Gross Motor Function Classification System Level I (n=24), Level II (n=16), or Level III (n=7). The 36-item Self-Perception Profile for Children was used to assess six domains of self-concept. No difference was found between the groups for Global Self-worth, Physical Appearance, or Behavioural Conduct. Children with CP scored lower on Scholastic Competence (t(92)=-2.75, p=0.01), Social Acceptance (t(92)=-1.96, p=0.05), and Athletic Competence (t(92)=-3.63, p<0.01) than children without impairment. Males with CP had lower scores for Scholastic Competence (t(46)=-3.54, p<0.01) than males without impairment. Females with CP had lower scores for Social Acceptance (t(44)=-2.31, p=0.03) than females without impairment. Both males and females with CP had lower scores for Athletic Competence than their peers without impairment. These results suggest that children with CP do not have a lower Global Self-worth even though they may feel less competent in certain aspects of their self-concept. Clinicians need to account for this when deciding on management strategies and may need to educate parents, carers, and health professionals that a lower self-concept may not necessarily be associated with a diagnosis of CP.

A prospective study was undertaken of 129 children with spastic cerebral palsy to clarify the relationship between magnetic resonance imaging (MRI) findings and clinical features of cerebral palsy. Low birth weight, asphyxia, prematurity, seizures, mental development, Gross Motor Function Classification System, and MRI findings were analyzed. Significant abnormalities relevant to the cerebral palsy were evident on imaging in 123 (95.3%). A similar percentage of MRI abnormalities were detected in the groups, 45 (100%) in patients with tetraplegic cerebral palsy, 37 (92.5%) in children with diplegic cerebral palsy, and 42 (95.4%) with hemiplegic cerebral palsy. Periventricular leukomalacia was detected more frequently in the children with spastic diplegia than in the patients with tetraplegia or hemiplegia. Cerebral atrophy was found more often in the tetraplegic group compared to the diplegic patients. Porencephalic cysts were detected more frequently in children with spastic hemiplegia. Congenital brain anomalies were found in a higher proportion in tetraplegic children. Significant correlations between the MRI findings and Gross Motor Function Classification System in the diplegic and tetraplegic patients were found. No correlations between the MRI results and risk factors for cerebral palsy in the tetraplegic patients were noted. Early detection of brain abnormalities in children with cerebral palsy may help in the prognosis and in the initiation of appropriate therapy

The aim of this study was to explore motor development in children with cerebral palsy (CP) using developmental curves for CP, subtypes, and the five severity levels of the Gross Motor Function Classification System (GMFCS). The Gross Motor Function Measure (GMFM) and the GMFCS were applied to 317 children (145 females, 172 males) with CP, aged between 1 and 15 years. The CP type distribution was spastic diplegia in 157 (49%), spastic hemiplegia in 101 (33%), spastic tetraplegia in 11 (3%), dyskinesia in 38 (12%), and ataxia in 10 (3%). Forty-five physiotherapists were trained in the GMFM and intra- and interrater reliability was tested. The GMFM was measured prospectively every 6 months up to the age of 4 years and once a year thereafter. Developmental curves were constructed for 258 children with spastic CP. About three-quarters of the children at GMFCS Level I reached 90% of the maximum GMFM score at 5 years of age. The performance peaked at 7 years of age. Children at GMFCS Level II reached 90% at a median age of 5 years, which was also the upper limit, reached by about three-quarters at 7 years of age. The majority of children at GMFCS Level III reached 80% of the GMFM by 7 years of age and most of the children at GMFCS Level IV reached 30% at 5 years and remained there. The median score for children at GMFCS Level V was 20%. The intra- and interrater reliability for the GMFM 88 among physiotherapists were Spearman's rank correlation coefficient 0.91 and 0.99 respectively. There were 931 measurements with a median of 2 (1-11) per child. The gross motor development was demonstrated for the five GMFCS levels in children with spastic CP. These kind of curves may be useful for monitoring and predicting motor development, for planning treatment, and for evaluating outcome after interventions.

Modelling the effect of soleus and gastrocnemius contractions against the floor resistance in a forward dynamics simulation revealed that hip flexion, internal rotation and adduction together with external pelvic rotation could be attributed to a direct, but distant effect of triceps surae contraction. Knee flexion smoothed out the effect. To validate this clinically relevant biomechanical observation, ankle plantar flexion was correlated with hip and pelvic rotation retrospectively in children with spastic cerebral palsy. In 49 children with spastic hemiplegia, plantar flexion showed a significant correlation with increased pelvic retraction and hip internal rotation. In contrast, in 47 children with spastic diplegia no significant effect of the triceps surae on hip and pelvis kinematics was found. Bilateral hip and knee flexion in diplegia appeared to prevent the proximal effect of the triceps surae seen in the hemiplegics. In diplegia triceps surae overactivity did not appear to be a significant cause of internal rotation gait.
