Abstract
Bilateral coordination is commonly impaired in neurodevelopmental conditions including cerebral palsy, developmental coordination disorder, and autism spectrum disorder. However, we lack objective clinical assessments that can quantify bilateral coordination in a clinically feasible manner and determine age-based norms to identify impairments. The objective of this study was to use augmented reality and computer vision to characterize bilateral reaching abilities in typically developing children. Typically developing children (n = 133) ages 6-17 years completed symmetric and asymmetric bilateral reaching tasks in an augmented reality game environment. We analyzed the number of target pairs they could reach in 50 s as well as the time lag between their hands reaching the targets. We found that performance on both tasks developed in parallel, with development slowing but not plateauing after age 12. Children performed better on the symmetric task than asymmetric, both in targets reached and with shorter hand lags. Variability between children in hand lag decreased with age. We also found gender differences with females outperforming males, which were most pronounced in the 10-11 year olds. Overall, this study demonstrates parallel development through childhood and adolescence of symmetric and asymmetric reaching abilities. Furthermore, it demonstrates the ability to quantify bilateral coordination using computer vision and augmented reality, which can be applied to assess clinical populations.

Abstract
PURPOSE To explore relevant parameters and investigate their test-retest reliability within the scope of the push button task of the Task-oriented Arm-hAnd Capacity (TAAC) measured in children with unilateral Cerebral Palsy (CP). METHODS 118 children diagnosed with unilateral CP, aged between 6 and 18 years, participated in this study. Thetest-retest reliability of the force generated during the push button task of the TAAC was investigated using an intraclass correlation (ICC) two-way random model with absolute agreement. The ICCs were calculated across the whole age group and for two separate age subgroups (6-12 and 13-18 years). RESULTS Test-retest reliability of the parameters "mean peak force of all attempts", "overshoot of force", "number of successful attempts" and "time to complete four successful attempts" were moderate to good (ICC range 0.667-0.865; 0.721-0.908; 0.733-0.817, respectively). CONCLUSIONS The results showed moderate to good test-retest reliability for all parameters. The parameters "mean peak force" and "number of successful attempts" are the most relevant parameters, as these parameters are task-specific and the most functional for clinical practice.Implications for RehabilitationClinical relevant information about the use of task-oriented strength during the performance of daily activity has been added to strength measurements in children with Cerebral Palsy.The Task-oriented Arm-hAnd Capacity instrument is a reliable, objective and simple instrument to measure task-oriented strength during daily activity and is ready for use in a clinical setting.The Task-oriented Arm-hAnd Capacity instrument is both a capacity and performance-based test.The measurement with the push button task showed moderate to good test-retest reliability.

Abstract
PURPOSE Hemiplegic cerebral palsy (hCP) typically impacts sensorimotor control of the hand, but comprehensive assessments of the hands of children with hCP are relatively rare. This scoping review summarizes the development of hand function for children with hCP. METHODS This scoping review focused on the development of hand function in children with hCP. Electronic databases (PubMed, PEDro, Web of Science, CINAHL, and SpringerLink) were searched to identify studies assessing hand function in children with hCP. The search was performed using keywords (e.g., "hemiplegia"). An iterative approach verified by two authors was used to select the studies. Articles which reported quantitative data for children with hCP on any items of a specified set of hand evaluations were included. Measures were sorted into three categories: quantitative neuromechanics, clinical assessments, and clinical functional evaluations. RESULTS Initial searches returned 1536 articles, 131 of which were included in the final review. Trends between assessment scores and age were examined for both hands. CONCLUSION While several studies have evaluated hand function in children with hCP, the majority relied on clinical scales, assessments, or qualitative descriptions. Further assessments of kinematics, kinetics, and muscle activation patterns are needed to identify the underlying impairment mechanisms that should be targeted for treatment.

Abstract
Original research articles regarding visual motor integration skills in children with developmental disabilities and the impact of occupational therapy were identified, appraised, and synthesized. Twenty-four articles were chosen for this review. Themes were noted during the critique of articles. Three themes emerged: "age," "gender," and "diagnosis." Regarding the impact on visual motor integration, there was strong evidence for age, moderate evidence for gender, and strong evidence for diagnosis. Future research investigating visual motor integration in children should control for age and diagnosis.

Abstract
Individuals with cerebral palsy have difficulties performing activities of daily living. Beyond motor execution impairments, they exhibit motor planning deficits contributing to their difficulties. The objective of this review is to synthesize the behavioral evidence of motor planning deficits during an upper limb motor task in children, adolescents and young adults with cerebral palsy aged between 3 and 21 years. Methods: The inclusion criteria were: (1) including individuals with cerebral palsy from 3 to 21 years old; (2) assessing upper limb motor planning. Six databases were screened. The quality assessment of the studies was performed. Results: Forty-six studies and 686 participants were included. Five articles have been identified as very high quality, 12 as high, 20 as moderate, six as low, three as very low. Force planning studies reported a deficit for the more affected hand but adequate performances for the less affected hand. Object-manipulation studies reported hand posture planning deficits irrespectively of the hand assessed. Conclusions: Motor planning deficits has been shown in the more affected hand for force scaling, while the results for other variables showed overall deficits. Hence, variables affected by motor planning deficits in both hands should be considered in children with cerebral palsy to optimize intervention.

Abstract
Background: Tools to assess bimanual coordination are scant. We aimed to: 1) provide normative data of maturation of bimanual coordination in tipically developing (TD) children measured by the Two Arm Coordination Test (TACT), and 2) validate the TACT as an instrument to specifically discriminate impairment of bimanual coordination in children with unilateral cerebral palsy (UCP). Procedure: Cross-sectional observational study. 252 TD children and 26 children with UCP performed 8 trials of TACT (following a star pattern with a pointer steered by coordinated movements of both arms). Number of errors and time were combined in a performance index of motor learning.Results: In TD children, bimanual coordination improved with age (F(7,244)=36.888, p<.001). Children with UCP had a poorer bimanual coordination than TD children (all t>24.25, all p<.01). TACT scores were correlated moderately to manual dexterity and manual ability (all r>-.452, all p<.039), showing the capacity of the TACT to provide information on different aspects of hand function. Conclusion: TACT is a valid instrument to assess bimanual coordination.

Abstract
Aim: To examine reproducibility of the arm-hand strength measured while performing the bimanual crate task and the unimanual pitcher task. Methods: 105 children diagnosed with unilateral Cerebral Palsy, aged between 6 and 18 years, participated in this study. The test-retest reliability of the force generated during bimanual crate task and unimanual pitcher task of the Task-oriented Arm-hAnd Capacity instrument was investigated using intraclass correlation two-way random model with absolute agreement. The intraclass correlations were calculated for two age groups (6-12 and 13-18 years old). Results: The results showed good test-retest reliability for the crate and pitcher task with the non-affected hand for both age groups. The results of the pitcher task for the affected hand showed moderate test-retest reliability for both age groups. Conclusion: The Task-oriented Arm-hAnd Capacity instrument has moderate to good test-retest reliability. It is a simple and objective instrument to assess task-oriented strength in children with unilateral cerebral palsy.

Abstract
Background: Patients with congenital and acquired hemiparesis incur long-term functional deficits, among which the loss of prehension that may impact their functional independence. Identifying, understanding, and comparing the underlying mechanisms of prehension impairments represent an opportunity to better adapt neurorehabilitation. Objective: The present review aims to provide a better understanding of precision grip deficits in congenital and acquired hemiparesis and to determine whether the severity and type of fine motor control impairments depend on whether or not the lesions are congenital or acquired in adulthood. Methods: Using combinations of the following key words: fingertip force, grip force, precision grip, cerebral palsy, stroke, PubMed, and Scopus databases were used to search studies from 1984 to 2013. Results: Individuals with both congenital and acquired hemiparesis were able to some extent to use anticipatory motor control in precision grip tasks, even if this control was impaired in the paretic hand. In both congenital and acquired hemiparesis, the ability to plan efficient anticipatory motor control when the less-affected hand is used provides a possibility to remediate impairments in anticipatory motor control of the paretic hand. Conclusion: Surprisingly, we observed very few differences between the results of studies in children with congenital hemiplegia and stroke patients. We suggest that the underlying specific strategies of neurorehabilitation developed for each one could benefit the other.

Abstract
BACKGROUND In order to make inferences about strength related to development or treatment interventions, it is important to use measurement instruments that have sound clinimetric properties. PURPOSE The objective of this review is to systematically evaluate the level of evidence of the clinimetric properties of instruments for measuring upper extremity muscle strength at the "body functions & structures" level of the International Classification of Functioning, Disability and Health for Children and Youth (ICF-CY) for children with cerebral palsy (CP). DATA SOURCES A systematic search of the PubMed, EMBASE, OTseeker, CINAHL, PEDro, and MEDLINE databases up to November 2012 was performed. STUDY SELECTION Two independent raters identified and examined studies that reported the use of upper extremity strength measurement instruments and methods for children and adolescents with CP aged 0 to 18 years. DATA EXTRACTION The COSMIN (COnsensus-based Standards for the selection of health status Measurement INstruments) checklist with 4-point rating scale was used by 2 independent raters to evaluate the methodological quality of the included studies. Best evidence synthesis was performed using COSMIN outcomes and the quality of the clinimetric properties. DATA SYNTHESIS Six different measurement instruments or methods were identified. Test-retest, interrater, and intrarater reliability were investigated. Two test-retest reliability studies were rated as "fair" for the level of evidence. All other studies were rated as "unknown" for the level of evidence. LIMITATIONS The paucity of literature describing clinimetric properties, especially other than reliability, of upper limb strength measurement instruments for children with CP was a limitation of the study. CONCLUSIONS For measuring grip strength, the Jamar dynamometer is recommended. For other muscle groups, handheld dynamometry is recommended. Manual muscle testing (MMT) can be used in case of limited (below MMT grade 4) wrist strength or for total upper limb muscle strength. Based on lacking information regarding other clinimetric properties, caution is advised regarding interpretation of the results.

Abstract
Children with hemiplegic cerebral palsy (HCP) exhibit long-term functional deficits. One of the most debilitating is the loss of prehension since this may impair functional independence. This loss of prehension could be partly due to sensory deficits. Identifying the underlying causes of prehension deficits and their potential link with sensory disorders is important to better adapt neurorehabilitation. Here we provide an overview of precision grip and sensory impairments in individuals with HCP, and the relation between them, in order to determine whether the sensory impairments influence the type and magnitude of deficits as measured by studies of prehensile force control. Pubmed and Scopus databases were used to search studies from 1990 to 2012, using combinations of the following keywords: fingertip force; grip force; precision grip; sensory deficit; sensory impairment; tactile discrimination; with cerebral palsy. Of the 190 studies detected through the systematic search; 38 were finally included in the systematic part of this review. This review shows that sensory deficits are common and are likely underestimated using standard clinical assessments in HCP. Some studies suggest these deficits are the basis of predictive motor control impairments in these individuals. However, children with HCP retain some ability to use predictive control, even if it is impaired in the more affected hand. Intensive practice and initial use of the less affected hand, which has only subtle sensory deficits, has been shown to remediate impairments in anticipatory motor control during subsequent use of the more affected hand. Implications for motor and sensory rehabilitation of individuals with HCP are discussed.

Abstract
The effects of dual-task constraints on bimanual coordination and walking in three age groups: young (4-6 years old), middle (7-9 years old), and older groups (10-13 years old) were examined. Children were asked to first walk along a path (baseline condition) and then to walk along the same path while carrying a box steady and level (dual-task condition). The young group showed less bimanual coordination with less level and more variable normalized vertical box positioning (mean hand differences, young: 3.68%, middle: 2.42%, older: 1.61%), less correlated hand movements (mean correlation, young: r(8)=0.58, middle: r(8)=0.77, older: r(8)=0.79), and more elbow and shoulder joint excursion on the dominant side (all Ps<0.05). In addition, the young group had shorter stride lengths and less normalized anterior/posterior ground reaction forces under the dual-task condition than the baseline condition (all Ps<0.05). These findings indicate that 4- to 6-year-old children might still be developing their ability to perform activities requiring dual-task constraints that involve simultaneous use of the upper and lower extremities.

Abstract
BACKGROUND Insights in upper limb impairments and their relationship with activity measures in children with unilateral cerebral palsy (CP) are important to optimize treatment interventions. AIMS (1) To investigate upper limb impairments and activity limitations in children with unilateral CP; (2) to compare these according to the Manual Ability Classification System (MACS), timing of lesion (congenital/acquired) and age; (3) to determine the impact of impairments on activity measures. METHODS Eighty-one children with unilateral CP aged 5-15 years (mean 9 years 11 months; congenital N=69, acquired N=12) were recruited. Body function measurements included passive range of motion (PROM), muscle tone, strength and sensibility. At activity level, the Melbourne Assessment, Assisting Hand Assessment (AHA) and Abilhand-Kids were assessed. RESULTS Most PROM limitations were found for elbow extension and supination. Increased tone and weakness were most prominent in distal muscles. Stereognosis and two-point discrimination were mostly affected. Children with a lower MACS level or acquired lesion had significantly more impairments and activity limitations. In children with congenital lesions, best predictors for unimanual capacity (Melbourne Assessment) were wrist strength, stereognosis and proprioception, and for bimanual performance (AHA) wrist strength and grip strength, explaining 76% of the variance. For the Abilhand-Kids, wrist strength and stereognosis predicted 46% of the variance. CONCLUSIONS Classification according to MACS and timing of lesion is important to differentiate within the wide range of impairments and activity limitations. In children with congenital lesions, unimanual capacity and bimanual performance are highly determined by distal strength, supporting the additional use of impairment-based interventions.

Abstract
BACKGROUND In children with unilateral cerebral palsy (CP), development of arm and hand function is often compromised by the underlying motor and sensory impairments. However, knowledge about the evolution of arm and hand function in this population is limited. AIM The aims were to map the evolution of scores on upper limb measures over one year in children with unilateral CP and to identify factors that influence time trends. METHODS Eighty-one children (43 males, 38 females; mean age 9y11mo (SD 3y3mo) range 5-15 y) were tested at baseline, at 6 and 12 months. According to the International Classification of Functioning, Disability and Health, body function measurements included passive range of motion, muscle tone, manual muscle strength and grip strength. Activity measurements included the Melbourne Assessment, the Jebsen-Taylor test, the Assisting Hand Assessment and the Abilhand-Kids questionnaire. Age, gender, etiology (congenital or acquired lesions) and Manual Ability Classification System (MACS) levels were analyzed as predictive factors, using mixed models. RESULTS Scores for grip strength (p = 0.001) and manual dexterity (Jebsen-Taylor test, p < 0.0001) increased significantly over time. MACS level (p = 0.03) and etiology (p = 0.02) had a significant influence on the time evolution of the Jebsen-Taylor scores. Other assessments showed no significant changes. CONCLUSION Motor impairments, movement quality and hemiplegic hand use in bimanual tasks do not spontaneously improve over one year, except for an age-related change in grip strength. However, an improvement was observed in manual dexterity, suggesting that some children can learn more adaptive movement strategies.
