Starting with finger foods is recommended from 7 months in typically developing children. However, information on which finger foods are appropriate and accepted for which age is largely lacking. The purpose of this exploratory study was to determine whether chewing skills, hand motor skills, and other personal and food characteristics influence the intake of finger foods in early life. Thirty children aged 12 to 18 months participated in this study. All children were offered four finger foods in a fixed order on four consecutive days at their home. Two finger foods varied mainly in texture (fresh banana vs. freeze-dried banana) and two other finger foods mainly in shape (stick vs. heart shaped cracker). The intake was measured after ten minutes of exposure to the product. Chewing skills were measured with the Mastication Observation and Evaluation instrument and fine motor skills with selected items of the Bayley-III-NL scales. The results suggest that texture but not shape was found to affect intake, as fresh banana was eaten more than freeze-dried banana and the consumed quantity of the two crackers was not significantly different. Hand motor skills affected the intake of fresh banana only and chewing skills did not affect intake of any of the finger foods. Age and experience with chewable foods were associated with an increased intake of some of the finger foods. In conclusion, the intake of the four finger foods in this study was found to be mainly affected by texture, hand motor skills, age and experience.

BackgroundFundamental Motor Skills (FMS) are important building blocks for children’s sport-participation and lifelong physical activity. In the last decade, several international studies have reported delays in the development of FMS. To get better insight into the Dutch situation and to provide future directions, this study examined the development of FMS in Dutch primary school children.MethodThe main goal of this study is to compare FMS of 11–12-year-old Dutch children in 2016 with scores of similarly-aged-children in 2006. In addition, gender, age, BMI were taken into account, to see whether changes in motor performance are related to these child characteristics. FMS-test scores on seven motor competence tests (balance, swing, jump, roll, shoot, throwing and catching, and tennis) from 1939 children in 2016 were set side by side with those of 1648 children in 2006. Temporal changes in motor competence scores were analyzed using regression-analysis.ResultsThis cross-sectional study shows better results for the children in 2006 compared to similarly-aged-children in 2016. Lower scores were found on six out of seven tested FMS, with the largest declines on the object control skills tennis and throwing and catching. Only vaulting jump skills remained on the same level. Overall, children with a higher BMI scored lower on all tests, except for throwing and catching via the wall. On the balancing, jumping and tennis test, the gap with children with a lower BMI widened over the last decade. Girls showed a lower competence level on rolling, shooting and throwing and catching compared to boys. During the last decade, their performance on the tennis test decreased more than for boys.ConclusionsResults of this study are alarming as diminishing motor skills are related to lower sport participation and poorer health outcomes. For the future generation, new interventions are needed to help children reach a sufficient proficiency level in FMS, to prevent or overcome the negative effects of lowered motor skills. Targeting FMS components during physical education and outside of school hours may potentially be a valuable strategy in reverting the lowering FMS levels amongst children.

Movement is an essential part of our lives. Throughout our lifetime, we acquire many different motor skills that are necessary to take care of ourselves (e.g., eating, dressing), to work (e.g., typing, using tools, care for others) and to pursue our hobbies (e.g., running, dancing, painting). However, as a consequence of aging, trauma or chronic disease, motor skills may deteriorate or become “lost”. Learning, relearning, and improving motor skills may then be essential to maintain or regain independence. There are many different ways in which the process of learning a motor skill can be shaped in practice. The conceptual basis for this thesis was the broad distinction between implicit and explicit forms of motor learning. Physiotherapists and occupational therapists are specialized to provide therapy that is tailored to facilitate the process of motor learning of patients with a wide range of pathologies. In addition to motor impairments, patients suffering from neurological disorders often also experience problems with cognition and communication. These problems may hinder the process of learning at a didactic level, and make motor learning especially challenging for those with neurological disorders. This thesis focused on the theory and application of motor learning during rehabilitation of patients with neurological disorders. The overall aim of this thesis was to provide therapists in neurological rehabilitation with knowledge and tools to support the justified and tailored use of motor learning in daily clinical practice. The thesis is divided into two parts. The aim of the first part (Chapters 2‐5) was to develop a theoretical basis to apply motor learning in clinical practice, using the implicit‐explicit distinction as a conceptual basis. Results of this first part were used to develop a framework for the application of motor learning within neurological rehabilitation (Chapter 6). Afterwards, in the second part, strategies identified in first part were tested for feasibility and potential effects in people with stroke (Chapters 7 and 8).

AimTo investigate: (a) language difficulties in children with developmental coordination disorder (DCD), and (b) motor difficulties in children with developmental language disorder (DLD).MethodIn this systematic review, PubMed, CINAHL, PsycINFO, and Embase were searched to identify peer-reviewed studies. Two researchers independently identified, screened and evaluated the methodological quality of the included studies following the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA). For objective (a), we combined the terms: “developmental coordination disorder” AND “language skills” AND “children”. For objective (b) we combined the terms: “developmental language disorder” AND “motor skills” AND “children”.ResultsTen studies on language skills in children with DCD and 34 studies on motor skills in children with DLD are included, most with relatively good methodological quality. The results for language comprehension and production in children with DCD are contradictory, but there is evidence that children with DCD have communication and phonological problems. Evidence for general motor problems in children with DLD is consistent. Studies report problems in balance, locomotor, and fine motor skills in children with DLD. Evidence for aiming and catching skills is inconsistent.InterpretationThe findings of this systematic review highlight the co-occurrence of language impairments in children with DCD and motor impairments in children with DLD. Healthcare professionals involved in the assessment and diagnosis of children with DCD or DLD should be attentive to this co-occurrence. In doing so, children with DCD and DLD can receive optimal interventions to minimize problems in their daily life.

BACKGROUND: Approximately 5%-10% of elementary school children show delayed development of fine motor skills. To address these problems, detection is required. Current assessment tools are time-consuming, require a trained supervisor, and are not motivating for children. Sensor-augmented toys and machine learning have been presented as possible solutions to address this problem.OBJECTIVE: This study examines whether sensor-augmented toys can be used to assess children's fine motor skills. The objectives were to (1) predict the outcome of the fine motor skill part of the Movement Assessment Battery for Children Second Edition (fine MABC-2) and (2) study the influence of the classification model, game, type of data, and level of difficulty of the game on the prediction.METHODS: Children in elementary school (n=95, age 7.8 [SD 0.7] years) performed the fine MABC-2 and played 2 games with a sensor-augmented toy called "Futuro Cube." The game "roadrunner" focused on speed while the game "maze" focused on precision. Each game had several levels of difficulty. While playing, both sensor and game data were collected. Four supervised machine learning classifiers were trained with these data to predict the fine MABC-2 outcome: k-nearest neighbor (KNN), logistic regression (LR), decision tree (DT), and support vector machine (SVM). First, we compared the performances of the games and classifiers. Subsequently, we compared the levels of difficulty and types of data for the classifier and game that performed best on accuracy and F1 score. For all statistical tests, we used α=.05.RESULTS: The highest achieved mean accuracy (0.76) was achieved with the DT classifier that was trained on both sensor and game data obtained from playing the easiest and the hardest level of the roadrunner game. Significant differences in performance were found in the accuracy scores between data obtained from the roadrunner and maze games (DT, P=.03; KNN, P=.01; LR, P=.02; SVM, P=.04). No significant differences in performance were found in the accuracy scores between the best performing classifier and the other 3 classifiers for both the roadrunner game (DT vs KNN, P=.42; DT vs LR, P=.35; DT vs SVM, P=.08) and the maze game (DT vs KNN, P=.15; DT vs LR, P=.62; DT vs SVM, P=.26). The accuracy of only the best performing level of difficulty (combination of the easiest and hardest level) achieved with the DT classifier trained with sensor and game data obtained from the roadrunner game was significantly better than the combination of the easiest and middle level (P=.046).CONCLUSIONS: The results of our study show that sensor-augmented toys can efficiently predict the fine MABC-2 scores for children in elementary school. Selecting the game type (focusing on speed or precision) and data type (sensor or game data) is more important for determining the performance than selecting the machine learning classifier or level of difficulty.

The increasing number of young children with a low proficiency in fundamental movement skills (FMS) emphasize the need to intervene. The purpose of a largescale Dutch study called Start(V)aardig is specifying elements that determine the effectiveness of motor interventions and translating these elements into an 18- week FMS intervention to stimulate motor competence level of young children.

The purpose of this study was to examine the feasibility and validity of an Athletic Skills Track (AST) to assess fundamental movement skills among 6- to 12-year-old children in a physical education setting. 463 Dutch children (211 girls, 252 boys) completed three tests: the Körperkoordination-Test für Kinder (KTK) and two Athletic Skills Tracks (AST-1, AST-2). The validity of AST-1 and AST-2 was examined by correlating the time (sec) needed to complete the tracks and the KTK Motor Quotient (KTK MQ). Overall, there was a small correlation between AST-1 and the KTK MQ (r = - 0.474 (p = 0.01)) and a medium correlation between AST-2 and the KTK MQ (r = - 0.502 (p = 0.01)). When split up by age group the associations between the Athletic Skills Tracks and the KTK MQ were large for 12-year old children (AST-1: r = - 0.767; AST-2: r = - 0.727) and smallest for 8-year olds with a medium association (AST-1: r = - 0.501; AST-2: r = - 0.469). The results suggest that children’s motor skills can be assessed with a quick, convenient, and low-cost motor competence test in a physical education setting, i.e. an Athletic Skills Track.

Abstract Aim: To determine whether the level of gross motor function and functional skills in children with cerebral palsy (CP) and cerebral visual impairment (CVI) as well as caregiver assistance are lower in comparison with the corresponding group of children experiencing CP without CVI. Method: Data aggregated from 23 children experiencing CP with CVI were compared with data from children with CP without CVI matched for Gross Motor Function Classifi cation System, mental development and age at testing. Scores for Gross Motor Function Measure-88 (GMFM-88) and the Pediatric Evaluation of Disability Inventory-NL (PEDI-NL) were employed to compare the level of gross motor function, functional skills and caregiver assistance between both groups. The Wilcoxon Signed Rank Test was utilized with a signifi cance level of p 0.05. Results: Children with CP with CVI, mean ( SD) age 6.4 1.5, scored signifi cantly lower than those with CP without CVI, mean age 6.3 1.6, on all GMFM-88 dimensions and the total score ( p 0.001) and on the PEDI-NL in the sections of Functional Skills and Caregiver Assistance as well as in those of domains self-care ( p 0.001), mobility ( p 0.001) and social functioning ( p 0.001). Concerning the modifi cations scale, the scores for children with CP and CVI were signifi cantly lower regarding mobility (no modifi cation , p 0.05), social functioning (no modifi cation, p 0.05) and social functioning (child-oriented, p 0.05). Conclusion: CVI contributes to diminished gross motor function and functional skills in children experiencing CP with CVI compared with children with CP without CVI. Children with CP and CVI also require increased support at the level of caregiver assistance. Specifi c interventions need to be developed for children experiencing CP with CVI in order to improve gross motor function, functional skills and caregiver assistance.

Objectives: The development of children’s motor competence (MC) from early to middle childhood can follow different courses. The purpose of this longitudinal study was to describe and quantify the prevalence of patterns of MC development from early to middle childhood and to identify undesirable patterns. Design: The study used a longitudinal design. Data were collected in three consecutive years, between February 2020 (T0) and May 2022 (T2). Methods: A total of 1128 typically developing Dutch children (50.2% male) between 4 and 6 years old at baseline (M = 5.35 ± 0.69 years) participated in this study. MC was measured with the Athletic Skills Track and converted into Motor Quotient (MQ) scores. To convert all individual MQ scores into meaningful patterns of MC development, changes in MQ categories were analyzed between the different timepoints. Results: A total of 11 different developmental patterns were found. When grouping the different patterns, five undesirable patterns were found with 18.2% of the children, showing an undesirable pattern of MC development between T0 and T2. The patterns of motor development of the other children showed a normal or fluctuating course. Conclusions: There is a lot of variation in MC in early and middle childhood. A substantial percentage of young children showed undesirable MC developmental patterns emphasizing the need for early and targeted interventions.

This dissertation describes the dynamics of motor competence (MC) development from early childhood (EC) to middle childhood (MCD). Being motor competent in early childhood creates a window of opportunity for taking part in physical activities later in childhood and adulthood. However, there is a worrying trend in MC development during childhood. This trend shows that, last decades, children struggle more with executing fundamental movement skills (e.g., hopping, dribbling, balancing, throwing and catching) and that general motor fitness levels of children are decreasing. A delay in MC development during childhood has a negative impact on the general health status later in life. Therefore, it is important to support young children to develop their MC. The main research question of this dissertation was: How can motor competence be promoted as efficient and effective as possible in early childhood by sport professionals? Chapter 2 showed that MC development from early to middle childhood proceeds with variation. The majority of the children had a stable ‘normal’ or increasing ‘high’ development of MC over time. However, a concerning level of 18.2% of the young children showed an undesirable pattern (i.e., a negative course of motor development over time and a ‘low’ MQ score during the final measurement) of MC development as they grow older. Chapters 3 and 4 showed that characteristics of the social and physical home environment and direct living environment were associated with MC disparities during early childhood. Both parenting practices and parental PA-involved behaviours were relevant modifiable factors. For example, stronger parental active transportation routines and PA parental practices decreased the odds of a lower MC. Also, the presence of a home garden decreased the likelihood of children being classified as low motor competent. With regard to gender differences, girls showed lower levels of MC compared to boys. Special attention should also be paid to obese children as they experience less enjoyment of PA compared with normal weighted peers (chapter 3). Excessive body weight is also a risk factor associated with an undesirable MC development, just like lack of sports participation (chapter 5). Intervention strategies (chapter 6) incorporating all fundamental movement skills with a great variety of activities for at least 3 to 4 times a week seem to be most effective to stimulate MC development. Methodological and didactical aspects like deliberate practice and play should be implemented together with training and coaching sessions for sport professionals to increase the effectiveness of the interventions. With respect to the efficiency of promoting MC development, policy makers and sport professionals should pay more attention on early childhood and especially focus on those children at risk for a delay in MC development. So, overweighted children and children not participating in organized sports should be given more attention by sport professionals. Additionally, the effectiveness of MC interventions can be increased by making use of the home environment, childcare context and school context of young children. Sport professionals can act as connectors between parents, school, and sports clubs.
