In the present study, we investigated the development of action planning in children with unilateral Cerebral Palsy (CP, aged 3-6 years, n=24) and an age matched control group. To investigate action planning, participants performed a sequential movement task. They had to grasp an object (a wooden play sword) and place the sword in a hole in a wooden block.(More)
The primary aim of this study was to assess the development of action planning in a group of typically developing children aged 3 to 10 years (N=351). The second aim was to assess reliability of the action planning task and to relate the results of the action planning task to results of validated upper limb motor performance tests. Participants performed an(More)
AIM To establish if there are psychometrically sound standardized tests or test items to assess handwriting readiness in 5- and 6-year-old children on the levels of occupations activities/tasks and performance. METHOD Electronic databases were searched to identify measurement instruments. Tests were included in a systematic review if: (1) participants are(More)
This study provides new norm scores for the Box and Block Test for gross manual dexterity in children ages 3-10 yr. Two hundred fifteen Dutch children performed the Box and Block Test separately with each hand. We found an age effect for the scores; older children obtained higher scores than younger children. Concurrent validity was assessed by means of(More)
Frailty is one of the greatest challenges for healthcare professionals. The level of frailty depends on several interrelated factors and can change over time while different interventions seem to be able to influence the level of frailty. Therefore, an outcome instrument to measure frailty with sound clinimetric properties is needed. A systematic review on(More)
This is the first meta-analysis focusing on elderly patients with mobility problems, physical disability and/or multi-morbidity. The aim of this study is to assess the effect of physical exercise therapy on mobility, physical functioning, physical activity and quality of life. A broad systematic literature search was performed in the databases PubMed,(More)
Albuterol, a selective beta-adrenergic agonist, has been used experimentally in combination with exercise therapy in a few inherited neuromuscular disorders to increase muscle strength and muscle volume . We report on a 9-year-old boy with central core disease and mitochondrial dysfunction due to compound heterozygous RYR1 mutations receiving albuterol(More)
Preterm birth increases the risk for neurologic and developmental disabilities and therefore long-term follow-up is important. This prospective follow-up study aims to describe longitudinal motor performance in preterm infants from 6 to 24 months and to detect the influence of risk factors on motor performance trajectories. We included preterm infants(More)
The article aims to discriminate between 2 features that in principle both may be characteristic of the frequently observed poor motor performance in girls with Turner's syndrome (TS). On the one hand, a reduced movement speed that is independent of variations in spatial accuracy demands and therefore suggests a problem in motor execution. On the other(More)
Children born preterm have a higher risk for developing motor, cognitive, and behavioral problems. Motor problems can occur in combination with working memory problems, and working memory is important for explicit learning of motor skills. The relation between motor learning and working memory has never been reviewed. The goal of this review was to provide(More)
