Hand function in children with hemiplegic cerebral palsy: prospective follow‐up and functional outcome in adolescence

The aim of this prospective study was to determine the outcome of affected hand impairment and disability in a group of 31 children (16 males, 15 females) with hemiplegic cerebral palsy who were referred consecutively to our rehabilitation service and followed from a mean age of 2 years and 7 months to a mean age of 12 years and 9 months. The hand function assessment protocol consisted of video-recorded procedures: one to assess grip and the other to assess the extent of spontaneous use of the affected hand. Assessments at outset and at latest follow-up showed that the series as a whole had greater hand impairment in spontaneous manipulation than in gripping tasks. Comparison of hand function before age 4 years with the latest assessment over age 11 years revealed a non-significant improvement in grip, whereas spontaneous hand use remained stable. All but one of the children who had good grip and hand use scores at first assessment maintained them over time unless they were not treated for hand dysfunction. Among the children with low scores at outset, the improvement over time was more marked in grip than spontaneous hand use and occurred mainly in the early years. These results suggest that to evaluate the real disability of the affected hand in children with hemiplegia, grip assessment is insufficient and that an instrument assessing spontaneous hand use in bilateral manipulation is required. Furthermore, intensive treatment focused on hand function should be planned in the early years for children with more severe hand impairment, whereas regular follow-up is sufficient for less affected children.

EYE-MOVEMENT DISORDERS AND VISUAL-PERCEPTUAL IMPAIRMENT IN DIPLEGIC CHILDREN BORN PRETERM : A CLINICAL EVALUATION

The visual‐motor behaviour of 15 preterm diplegic children and 50 control children (age range 4 to 7 years) was recorded on video as they performed a visual‐perceptual task (an adaptation of the Animal House subtest of the Wechsler Preschool Primary Scale of Intelligence). The following parameters were analysed and scored: time to perform task; omissions; figure‐colour association; sequence direction; sequential scanning order; accuracy of fitting target; and number of anticipatory saccadic movements to next target. The ability of the control children to perform the task improved significantly with age, as measured by performance time, mistakes in sequence direction and scanning order, accuracy of target fitting, and number of anticipatory saccadic movements. The scores of children with diplegia were not related to age and were poorer overall than those of the control group. Children with diplegia made significantly more mistakes of sequence direction and scanning order, and significantly fewer anticipatory saccadic movements than the control group. These results indicate that visual‐perceptual impairment in diplegic children born preterm is not attributable only to sensory visual loss and to fine manipulation difficulties but is also related to difficulties in eye movements and in using anticipatory control to process information.

Cognitive Profiles and Visuoperceptual Abilities in Preterm and Term Spastic Diplegic Children With Periventricular Leukomalacia

Although relations between the extent of periventricular leukomalacia and neuropsychological performance in preterm children with spastic diplegia have been extensively investigated, studies on term children with spastic diplegia are rare. The authors examined 15 preterm children and 9 term children with spastic diplegia, all of whom had periventricular leukomalacia as a main magnetic resonance imaging (MRI) finding (excluding full-term spastic diplegic children with other MRI findings). Cognitive abilities (Griffith scale) and visuoperceptual abilities (Developmental Test of Visual Perception) were compared in the 2 groups and related to periventricular leukomalacia severity. Cognitive performance was substantially similar in the 2 groups. However, the overall Developmental Test of Visual Perception scores were below normal in the preterm and were normal in the term children; furthermore, visuoperceptual abilities were differentially affected in the preterm children, with visuomotor abilities more compromised than nonmotor visuoperceptual abilities. These children had similar cognitive performance and MRI findings, so the greater visuoperceptual compromise in the preterm group suggests a direct influence of prematurity, which may have adversely influenced the reorganization of visual centers and pathways following the initial developmental insult. The strabismus present in most preterm children would also have contributed to their greater visuoperceptual compromise. The authors conclude that the management of preterm and term children should differ, with concentration on visuoperceptual skills and rehabilitation in the former.

Multisite trial comparing the efficacy of constraint-induced movement therapy with that of bimanual intensive training in children with hemiplegic cerebral palsy: postintervention results.

Objective: The aim of this study was to compare the effects of modified constraint-induced movement therapy (mCIMT; restraint of unaffected limb combined with unimanual intensive rehabilitation) with those of a bimanual intensive rehabilitation treatment (IRP) in children with hemiplegic cerebral palsy after a 10-wk practice vs. standard treatment (ST). Design: This study is a multicenter, cluster-randomized controlled clinical trial of tested groups of children with hemiplegic cerebral palsy treated using mCIMT, IRP, or ST. For 10 wks, in mCIMT and IRP, the intensive practice lasted 3 hrs/day, 7 days/wk; in ST, 1-hr sessions twice a week were provided. The primary outcomes are upper limb/hand function (Quality of Upper Extremity Skills Test) and activities of daily living (Besta Scale), which are assessed before and after treatment. One hundred five patients were recruited, 39 to the mCIMT group, 33 to the IRP group, and 33 to the ST group. Results: IRP and mCIMT significantly improved paretic hand function both in the Quality of Upper Extremity Skills Test and in the Besta Scale, whereas ST did not. mCIMT improved grasp more than IRP did (P < 0.01), whereas bimanual spontaneous use in play increased more with IRP (P = 0.0005). Activities of daily living in 2- to 6-yr-olds improved more with IRP (P < 0.0001) than with mCIMT (P = 0.011). Unaffected limb improved more from bimanual practice (IRP; P = 0.02). Conclusions: More advantages resulted from intensive practice than in the standard one, in mCIMT for grasp and in IRP for bimanual spontaneous use and activities of daily living in younger children.

Predictors of Independent Walking in Children With Spastic Diplegia

A prospective study was carried out to identify predictors of independent walking in 31 children with either spastic diplegia or triplegia, observed from the age of 9 to 18 months (mean, 11 months) and followed for a mean period of 30 months (range, 24 to 36 months). Mean age at most recent examination was 41 months (range, 36 to 54 months). We used an 18-item scheme to chart the acquisition, from the prone position, of prelocomotor, sitting, and locomotor skills. Examinations were conducted every 6 months and videotaped according to a standardized procedure. At latest assessment 18 (58%) of the 31 children had achieved walking, 7 (23%) independently and 11 (35%) with assistance; 13 (42%) did not achieve walking. Ambulatory status was related to developmental quotient and visual acuity: all the children who became independent walkers had normal visual acuity and in 86% of cases a normal general development quotient. Moreover, we found a significant correlation between the number of gross motor skills achieved and the rate of achievement before 2 years of age and ambulatory status at 3 to 5 years of age. Ability to put weight on the hands while prone and to roll from supine to prone position by 18 months of age were significantly related to independent walking, while ability to sit without support was predictive only at around 24 months of age.

Unimanual and Bimanual Intensive Training in Children With Hemiplegic Cerebral Palsy and Persistence in Time of Hand Function Improvement 6-Month Follow-Up Results of a Multisite Clinical Trial

This study aims to compare in hemiplegic children the effectiveness of intensive training (unimanual and bimanual) versus standard treatment in improving hand function, assessing the persistence after 6 months. A multicenter, prospective, cluster-randomized controlled clinical trial was designed comparing 2 groups of children with hemiplegic cerebral palsy, treated for 10 weeks (3 h/d 7 d/wk; first with unimanual constraint-induced movement therapy, second with intensive bimanual training) with a standard treatment group. Children were assessed before and after treatment and at 3 and 6 months postintervention using Quality of Upper Extremity Skills Test (QUEST) and Besta Scales. One hundred five children were recruited (39 constraint-induced movement therapy, 33 intensive bimanual training, 33 standard treatment). Constraint-induced movement therapy and intensive bimanual training groups had significantly improved hand function, showing constant increase in time. Grasp improved immediately and significantly with constraint-induced movement therapy, and with bimanual training grasp improved gradually, reaching the same result. In both, spontaneous hand use increased in long-term assessment.

Multisite Trial on Efficacy of Constraint-Induced Movement Therapy in Children with Hemiplegia : Study Design and Methodology

Facchin P, Rosa-Rizzotto M, Turconi AC, Pagliano E, Fazzi E, Stortini M, Fedrizzi E, The Gipci Studi Group: Multisite trial on efficacy of constraint-induced movement therapy in children with hemiplegia: study design and methodology. Am J Phys Med Rehabil 2009;88:216-230. Objective:In the past decades, several treatment approaches have been used to improve upper limb function in hemiplegic cerebral palsy. Only recently has constraint-induced movement therapy emerged as a treatment approach for children with hemiplegic cerebral palsy with the aim of reversing the behavioral suppression of movement in the affected upper limb. To date, evidence on this treatment has been very poor and limited, because all currently available trials reveal methodological limitations and a need for additional research to support the application of this treatment technique. This article presents the methodological choices, design, and main characteristics of an ongoing controlled clinical trial on the effectiveness and safety of constraint-induced movement therapy combined with an intensive rehabilitation program and compared with two comparison groups: one treated with an intensive rehabilitation program and the other with standard treatment. Methods:Twenty-one rehabilitation sites are currently recruiting patients with hemiplegic cerebral palsy, aged between 2 and 8 yrs, who have never undergone constraint therapy. Primary outcome measures include two major domains: upper limb motor ability (Quality of Upper Extremity Skills Test) and hand function assessment evaluating both grip function and spontaneous use of the affected side (Besta scale). Secondary outcome measures concern overall function, behavior, compliance, and satisfaction with treatment program of both child and family. Patients’ follow-up is of 12 mos after treatment. Results:Research in children has always been neglected in comparison with adults, because of ethical reasons regarding the use of children for experimental purposes. The consequence has been the utilization of treatment and assessment tools and techniques that have not always been tested in pediatric patients or evidence is very scarce. Conclusion:Discussing and working on pediatric research methods represents an urgent need in rehabilitation research.

Developmental sequence of postural control in prone position in children with spastic diplegia

The aim of this study was to assess the development of postural control in the prone position in children with spastic diplegia and triplegia, and determine the influence of clinical characteristics, visual acuity and cognitive performance on that development. We also analysed the relation between these early motor achievements in the prone position and the subsequent acquisition of motor competence in the sitting position. We followed 24 diplegic and triplegic children from before age 2 years (mean age 12 months) to mean age 41 months, videorecording motor behaviour every six months and abstracting acquisitions in alignment and balance using a standardised procedure. We confirm a developmental sequence of all the acquired movements in the prone position. 83.3% of the children completed the uprighting sequence in the sagittal plane, acquired good balance, and ability to rotate the head and trunk. 70.8% of the children (all but one of the diplegic children and none among triplegic children) acquired symmetric posture in the frontal plane and 83.3% reduced leg hyperextension. Development was not uniform, and at 12-18 months two groups began to emerge: diplegic children who rapidly achieved all or most of the steps in the sequence and had a favourable prognosis for subsequent motor development; and triplegic children who achieved these steps at a much slower rate or in some cases not at all and had a less favourable prognosis for future development. Diplegic children with normal visual acuity, and general quotient GQ>70 did better than triplegic children with compromised visual acuity and GQ<70. Acquisition of the full uprighting sequence in the prone position before the age of two related to the later acquisition of autonomous sitting.

Peripheral sensory neuropathy in childhood.

A case of peripheral sensory neuropathy is described in a 51/2‐year‐old boy whose paternal grandmother and maternal grandfather were first cousins. The child had developed bullae on the tips of his fingers between six and twelve months of age, trophic changes had appeared on his hands during his second year, and there was complete destruction of the terminal phalanges of eight fingers at four years. At this age it was also noticed that he did not experience pain from a burn on the leg.
