Signs of perceptual disorder during movement were reliably assessed in children with cerebral palsy in Sweden.

AIM: The aim of this Swedish study was to evaluate the assessment of clinical signs of perceptual disorder in children with cerebral palsy (CP). METHODS: Three experienced raters assessed 56 videos of 19 children from 1 to 18 years of age with bilateral spastic CP, which were recorded by colleagues at an Italian hospital. Six signs were evaluated for inter-rater reliability and criterion validity. Clinical applicability was evaluated by assessing inter-rater reliability between 47 Swedish clinicians, who examined 15 of the videos during face-to-face and online education seminars. There were 41 physiotherapists, two occupational therapists and four doctors, with 1-37 years of clinical experience and a median of 10 years. RESULTS: The experienced raters demonstrated moderate to almost perfect inter-rater reliability (kappa 0.54-0.81) and criterion validity (0.54-0.87) for startle reaction, upper limbs in startle position, averted eye gaze and eye blinking. The clinicians recognised these signs with at least moderate reliability (0.56-0.88). Grimacing and posture freezing were less reliable (0.22-0.35) and valid (0.09-0.50). CONCLUSION: Four of the six signs of perceptual disorder were reliably recognised by experienced raters and by clinicians after education seminars. Extended education and larger study samples are needed to recognise all the signs.

Are perceptual disorder signs in diplegic cerebral palsied children stable over time? A retrospective cohort analysis.

BACKGROUND: A group of diplegic cerebral palsied (CP) children presents six precise signs that can be easily observed during clinical examinations, physiotherapy sessions and everyday activities. These signs are: startle reaction, upper limbs in startle position, averted-eye gaze, grimaces, eye blinking and posture freezing. METHODS: In a population of 32 diplegic CP children (aged 1-8 years) perceptual signs were retrospectively identified through videos to verify their stability in the same child over time. RESULTS: Startle reaction, upper limb in startle position and posture freezing were the most frequently observed signs and the easiest to recognize with the highest agreement in both observations (P<0.001). Eye signs (eye blinking and averted-eye gaze) were more difficult to detect in our recordings. CONCLUSIONS: Signs of perceptual disorders were present in our sample of diplegic CP children from the second year of age and could still be observed after 1- to 3-year intervals, demonstrating they remain unaltered over time. Furthermore, if absent in the first observation, they did not appear later on. CP children with these perceptual signs could represent a new clinical entity, which we are currently describing and defining.

Sitting Postural Management to Prevent Migration Percentage Progression in Non-Ambulatory Children with Cerebral Palsy: Randomized Controlled Trial Preliminary Data.

Background/Objectives: To determine whether a sitting position with the femoral heads centered into the acetabulum is more effective than the usual sitting position in preventing migration percentage progression in non-ambulatory children with bilateral cerebral palsy. Methods: This was a multicenter, randomized controlled trial. INCLUSION CRITERIA: spastic or dyskinetic cerebral palsy, Gross Motor Function Classification System level IV-V, age 1-6 years, migration percentage <41%, and informed consent. EXCLUSION CRITERIA: contractures affecting the hip, anterior luxation, previous hip surgery, and lumbar scoliosis. The treatment group sat with their hips significantly abducted to reduce the head into the acetabulum in a customized system for at least five hours/day for two years. Controls sat with the pelvis and lower limbs aligned but the hips less abducted in an adaptive seating system. The primary outcome was migration percentage (MP) progression. Health-related quality of life and family satisfaction were among the secondary outcomes. The study was approved by the local ethics board and conducted in accordance with CONSORT reporting guidelines. CLINICALTRIALS: gov ID: NCT04603625. RESULTS: Overall median MP progression was 1.6 after the first year and 2.5 after the second year. No significant differences were observed between the groups. MP exceeded 40% and 50% in 1.8% and 0% of the experimental group and 5.4% and 3.6% of controls in years 1 and 2, respectively. Both groups expressed satisfaction with the postural system and stable health-related quality of life. Conclusions: MP remained stable over the two-year period in both groups. Considering outliers which progressed over 50%, a more protective trend of the hip-centering sitting approach emerged, but this needs to be confirmed in a final, larger dataset.

Construct Validity of the Activities Scale for Kids Performance in Children with Cerebral Palsy: Brief Report.

Aims: This study collects evidence of construct convergent validity of the Activity Scale for Kids performance (ASKp), comparing its results with the 66-item Gross Motor Function Measure (GMFM-66) and with the Gross Motor Function Classification System (GMFCS) and testing the ASKp's ability to discriminate between individuals with different functional capabilities. Methods: This cross-sectional study involved 60 children with spastic cerebral palsy (CP) assessed with the GMFM-66 who self-administered the Italian version of the ASKp. Results: Children were 10.9 (±3) years old with GMFCS Level I-III. Moderate correlations were found between GMFM and ASKp scores (r = 0.577; p < .001), and between GMFCS levels and ASKp score (rs = -0.541, p < .001). The ASKp discriminated between children with different functional capabilities, determined by the GMFCS (F = 18.2, p < .001). Conclusions: ASKp is valid to assess physical functioning, a crucial domain in rehabilitation of children with spastic CP. Trial registration: ClinicalTrials.gov Identifier: NCT03325842.

Evaluation of hand function in patients with unilateral cerebral palsy who underwent multilevel functional surgery: a retrospective observational study.

BACKGROUND: Hemiplegia is the most common form of cerebral palsy. Upper limb is generally more affected than lower one. Indeed, hemiplegic children can spontaneously acquire standing and walking ability, while manipulation remains uncertain, with severe limitations in activity and participation, which define a child's functional status (International Classification of Functioning [ICF]). Several non-surgical tools are currently available to approach upper limb impairments. Studies regarding upper limb multilevel surgery in Hemiplegic Cerebral Palsy are relatively few and inhomogeneous. AIM: The aim of this study is to propose a surgical approach based on upper limb functional level and manipulation strategy and establish whether multilevel surgery can improve segmental alignment, performance and capacity, that ICF defines as activities and participation qualifiers. DESIGN: This study is an observational retrospective study. SETTING: This study involves patients who referred to the Unit of Children Rehabilitation of S. Maria Nuova Institute for Research and Care, in Reggio Emilia (Italy), over a four-year period. POPULATION: Children affected by hemiplegic cerebral palsy who underwent upper limb multilevel surgery. METHODS: For each patient, we previously defined functional use of affected upper limb applying the House classification and the Ferrari one of manipulation pattern. Patients are divided into three groups: synergic hand (House 4, 5), imprisoned hand (House 3), excluded hand (House 0). We recorded goals achievement through Goal Attainment Scale and unimanual and bimanual abilities through Melbourne Assessment of Unilateral Upper Limb Function and through Assisting Hand Assessment respectively. RESULTS: We recorded 16 upper limb multilevel surgical interventions in 13 children and report their results. CONCLUSIONS: This study suggests that surgery can induce a segmental and/or aesthetic and/or a functional change depending on manipulation pattern. It also underlines the importance to analyze results in term of spontaneous manipulation abilities and daily use. CLINICAL REHABILITATION IMPACT: This study provides a preliminary guide to plan surgery in relation to segmental deformities and overall manipulation pattern and describes their feasible improvement measures. It also suggests the most useful tools to record goal achievements in modifying manipulation function. Further controlled, randomized and prospective studies are required to support this idea.

A randomized trial of upper limb botulimun toxin versus placebo injection, combined with physiotherapy, in children with hemiplegia.

The main goal of this study was to investigate the efficacy of Botulinum Toxin A (BoNT-A), combined with an individualized intensive physiotherapy/orthoses treatment, in improving upper limb activity and competence in daily activity in children with hemiplegia, and to compare its effectiveness with that of non-pharmacological instruments. It was a Randomized Clinical Trial of 27 children with spastic hemiplegic cerebral palsy, outpatients of two high speciality Centres for child rehabilitation. Each child was assigned by simple randomization to experimental group (BoNT-A) or control group (placebo). Assisting Hand Assessment (AHA) was chosen as primary outcome measure; other measures were selected according to ICF dimensions. Participants were assessed at baseline (T0), at T1, T2, T3 (1-3-6 months after injection, respectively). Every patient was given a specific physiotherapeutic treatment, consisting of individualized goal directed exercises, task oriented activities, daily stretching manoeuvres, functional and/or static orthoses. BoNT-A group showed a significant increase of AHA raw scores at T2, compared to control group (T2-T0: p=.025) and functional goals achievement (GAS) was also slightly better in the same group (p=.033). Other measures indicated some improvement in both groups, without significant intergroup differences. Children with intermediate severity of hand function at House scale for upper limb impairment seem to have a better benefit from BoNT-A protocol. BoNT-A was effective in improving manipulation in the activity domain, in association with individualized goal-directed physiotherapy and orthoses; the combined treatment is recommended. The study brings more evidence for the efficacy of a combined treatment botulinum toxin injection-physiotherapy-orthoses, and it gives some suggestions for candidate selection and individualized treatment.
