The more recent studies evaluating strength training mainly demonstrated level II evidence for improved gait and gross motor function. There was limited evidence for specific information on intensity, duration and frequency of training.

Aim To investigate the underlying factor structure of the 46‐item Flemish cerebral visual impairment (CVI) questionnaire, differentiate the factor scores of children with and without CVI, and examine the impact of comorbidities on factor scores. Method The records of 630 children (386 males, 244 females; median age 77mo; interquartile range 63–98mo) who visited the CVI clinic and the Centre for Developmental Disabilities at the University Hospitals of Leuven from 2001 to 2018 were reviewed systematically. Inclusion criteria included an up‐to‐date questionnaire, a definitive diagnosis, and clinical assessment. Results Three hundred and forty‐five children (179 with CVI [108 males, 71 females; median age 74mo; interquartile range 61–93mo] and 166 without CVI [110 males, 56 females; median age 88mo; interquartile range 70–107mo]) were included. An exploratory factor analysis resulted in a 5‐factor (object and face processing impairments; visual (dis)interest; clutter and distance viewing impairments; moving in space impairments; and anxiety‐related behaviours) biologically and clinically plausible model, which retained 35 items and explained 56% of the total variance. Mann–Whitney U tests indicated that factors 1 to 4 were significantly higher in children with CVI compared to children without CVI (p‐values ranged from p<0.001 to p<0.05; effect sizes ranged from 0.11 to 0.33); factor 5 showed no differences. Autism, developmental coordination disorder, epilepsy, and cerebral palsy impacted factor scores. Interpretation A 5‐factor structure of the Flemish CVI questionnaire differentiates children with and without CVI. Comorbidities should be accounted for when researching CVI. What this paper adds Cerebral visual impairment (CVI) is characterized by impaired object and face processing and impaired visual interest. CVI is also characterized by impaired clutter and distance viewing, and impaired moving in space. All children (with or without CVI) demonstrated anxiety‐related behaviours. Autism affected object/face processing, whereas developmental coordination disorder, epilepsy, and cerebral palsy affected visual interest.

Level II evidence was found for the effectiveness of therapeutic horse-riding on posture and for NDT and functional training on gross motor function. Goal-oriented therapy and functional training were effective on the attainment of functional goals and participation. With level IV evidence, NDT was effective on all levels of the ICF.

BackgroundDiffusion magnetic resonance imaging (dMRI) is able to detect, localize and quantify subtle brain white matter abnormalities that may not be visible on conventional structural MRI. Over the past years, a growing number of studies have applied dMRI to investigate structure-function relationships in children with cerebral palsy (CP). AimsTo provide an overview of the recent literature on dMRI and motor function in children with CP. MethodsA systematic literature search was conducted in PubMed, Embase, Cochrane Central Register of Controlled trials, Cinahl and Web of Science from 2012 onwards. ResultsIn total, 577 children with CP in 19 studies were included. Sixteen studies only included unilateral CP, while none included dyskinetic CP. Most studies focused on specific regions/tracts of interest (n=17) versus two studies that investigated the whole brain. In unilateral and bilateral CP, white matter abnormalities were widespread including non-motor areas. In unilateral CP, consistent relationships were found between white matter integrity of the corticospinal tract and somatosensory pathways (e.g. thalamocortical projections, medial lemniscus) with upper limb sensorimotor function. The role of commissural and associative tracts remains poorly investigated. Also results describing structurefunction relationships in bilateral CP are scarce (n=3). ConclusionsThis review underlines the importance of both the motor and somatosensory tracts for upper limb sensorimotor function in unilateral CP. However, the exact contribution of each tract requires further exploration. In addition, research on the relevance of non-motor pathways is warranted, as well as studies including other types of CP. What this paper adds• An overview of the current literature investigating the relationship between diffusion MRI based measures of white matter tract integrity and motor function in CP.• Current gaps and future recommendations to further improve our insights into these structurefunction relationships. Highlights• In unilateral and bilateral CP, white matter microstructural abnormalities are widespread including non-motor areas.• In unilateral CP, dMRI reveals a relationship between the microstructural properties of motor and somatosensory tracts and upper limb sensorimotor function.• The contribution of motor versus somatosensory tracts needs further clarification.• There are limited studies in bilateral spastic CP and in children with dyskinetic CP.

The Gross Motor Function Measure-88 can be reliably scored using video recordings. The agreement between live and video scores is lower than the intra-rater reliability using video recordings only. Future clinical trial results should be interpreted using the appropriate SEM and SDC values.
