Purpose: This study aimed (1) to evaluate the test–retest reliability of a new agility test among children and (2) to determine the physical performance and anthropometric variables that may influence agility performance in this population. Methods: For aim 1, participants (n = 34) completed the Ladder Agility Test (LAT) twice, with a 2-week interval between the first and second test occasions. For aim 2, participants (n = 125) were assessed on the LAT as well as other measures thought to be necessary for agility such as motor coordination, explosive power of the lower extremity, dynamic balance, age, and body mass index. Results: Intraclass correlation coefficient of the LAT total score was.94 (95% confidence interval,.88–.97). Cronbach alpha of.85 was found between the 4 test items. An R
2 of.466 was found to represent the explained variance of the LAT total score by the predicting variables. Dynamic balance (2-legged side jumps) (P <.001), motor coordination (P <.01), and age (P <.06) were found to be the major predictors of the LAT total score. Conclusions: This study shows that the LAT is a reliable and valid field-based test that can be used to evaluate agility performance in children. Factors such as dynamic balance, motor coordination, and age may influence agility performance. [ABSTRACT FROM AUTHOR]- Published

- Abstract
This study was performed to determine (a) the age at which autism spectrum disorder (ASD) is first diagnosed in Ugandan children receiving mental health services, (b) whether age at diagnosis varies by sex and clinical presentation, and (c) the average age of ASD diagnosis in children manifesting comorbid conditions. A retrospective chart review was performed and demographic as well as clinical data were collected from children with ASD diagnoses who attended two mental health clinics in Uganda between 2014 and 2019. Descriptive statistics such as percentages, means, and standard deviations were used to summarize the data. Independent t‐test was also performed to determine differences in the mean age of diagnosis between males and females. Two hundred and thirty‐seven (156 males, 81 females) children with ASD were identified. The average age of ASD diagnosis was (6.9 ± 4.0) years. A statistically significant difference in age of ASD diagnosis was found between males and females (t = −2.106, p = 0.036), such that on average females received a diagnosis at least 1 year later than males. Of the 237 participants, 53.6% were identified with ASD only, 16.0% had ASD and ADHD, 10.5% were diagnosed with ASD and epilepsy, and 7.2% had a diagnosis of complex ASD. The results confirm delays in access to ASD diagnosis and suggest that females are more likely to receive a ASD diagnosis later than males within the Ugandan context. ASD awareness should be intensified to improve public or professional knowledge about ASD to enhance early identification in Uganda. Lay Summary: Data were extracted from the medical folders of children with a diagnosis of autism spectrum disorder (ASD) receiving mental health services in Central Uganda. We showed that female children receive ASD diagnosis at least 1 year later than males. In addition, in some children, ASD was diagnosed alongside other comorbidities such as ADHD and epilepsy.

Background: Numerous movement skills and physical fitness tests have been developed for children in high-income countries. However, adaptation of these tests to low-resource settings has been slow and norms are still unavailable for children living in low-income communities. The aim of this paper was to describe the development and validation of the Performance and Fitness (PERF-FIT) test battery, a new test to assess motor skill-related physical fitness in children in low-resource settings.Method: The PERF-FIT test was developed in a stepwise manner. This involved defining the relevant domains of the construct of interest and selecting and evaluating test items. The Content Validity Index (CVI) was used to estimate content validity. Following development of the PERF-FIT test, a preliminary study was performed to validate items and to examine the feasibility of implementing the test in a low-resource community. Structural validity was also determined based on data from eighty (n = 80) children (aged 7-12 years) using principal component analysis.Results: The CVI for the throw and catch item was 0.86 and 1.00 for the other nine items, leading to a total CVI score of 0.99. The hierarchical sequence of the item series was demonstrated by highly significant (p < 0.001) linear trends, confirming the increase in difficulty of subsequent items. Principal component analysis revealed three factors; the first component is represented by locomotor skills that require static and dynamic balance, the second component by throwing and catching items and the third component by agility and power items. These findings suggest that it is feasible to implement the PERF-FIT in low-resource settings.Conclusion: The PERF-FIT test battery is easy to administer and may be suitable for measuring skill-related physical fitness in in low-resource settings. It has excellent content validity and good structural validity. After minor adaptions, further studies should be conducted to establish normative values, evaluate reliability, and document criterion and cross-cultural validity of this test.

Background: Assessment of anaerobic capacity in children with Developmental Coordination Disorder (DCD) is essential for treatment planning. However, available field-based measures have no established validity and reliability in this population. Purpose: To examine the psychometric properties of selected field-based anaerobic capacity tests in children with and without DCD. Methods: School-aged children (6–16 years) with and without DCD participated in the study. The children completed the shuttle run sub-item of the Bruninks-Oseretsky test of motor proficiency-second edition, the 10 × 5 m sprint tests (straight and slalom) and the muscle power sprint test (MPST). Results: The shuttle run test item of the Bruninks-Oseretsky test of motor proficiency-second edition and 10 × 5 m sprint tests possess good construct validity and test–retest reliability in children with DCD. The 10 × 5 m sprint test-slalom was found to be the most responsive test among children with DCD. However, the MPST was less reliable in children with DCD compared to their typically developing peers, leading to a very large Smallest Detectable Difference. Conclusions: The findings suggest that the selected anaerobic capacity measures have sound psychometric properties among children with DCD with the exception of the MPST. Clinicians working on children with DCD could use these tests in their practice, especially in situations where logistical resources are limited. Field-based anaerobic capacity tests are suitable measures for assessing anaerobic capacity in children with Developmental Coordination Disorder, particularly in situations where laboratory assessments are not feasible. The shuttle run test item of the Bruninks-Oseretsky test of motor proficiency-second edition and the 10 × 5 sprint tests (straight and slalom) have good construct validity in this population. The 10 × 5 sprint test (slalom) is the most sensitive anaerobic capacity test among children with Developmental Coordination Disorder. [ABSTRACT FROM AUTHOR]

Background: Adolescents with low motor competence participate less in physical activity and tend to exhibit decreased physical fitness compared to their peers with high motor competence. It is therefore essential to identify new methods of enhancing physical fitness in this population. Active video games (AVG) have been shown to improve motor performance, yet investigations of its impact on physical fitness are limited. The objective of this study was to examine the impact of the graded Wii protocol in adolescent girls with probable Developmental Coordination Disorder (p-DCD).Methods: A single-group pre-post design was conducted to assess the impact of a newly developed Wii protocol in adolescent girls attending school in a low income community of Cape Town, South Africa. Sixteen participants (aged 13-16 years) with p-DCD (≤16th percentile on the MABC-2 test) were recruited. Participants received 45 min Wii training for 14 weeks. Outcome measures included the six-minute walk distance and repeated sprint ability. Information on heart rate, enjoyment and perceived exertion ratings were also collected.Results: Significant improvements in aerobic and anaerobic fitness were observed. The participants reported high enjoyment scores and low perceived exertion ratings. The graded Wii protocol was easily adaptable and required little resources (space, equipment and expertise) to administer.Conclusions: The findings provide preliminary evidence to support the use of the graded Wii protocol for promoting physical fitness in adolescent girls with p-DCD. Further studies are needed to confirm these results and to validate the clinical efficacy of the protocol in a larger sample with a more robust design. [ABSTRACT FROM AUTHOR]- Published

Background: This systematic review was conducted with the first objective aimed at providing an overview of the physiological characteristics commonly evaluated in rugby and the corresponding tests used to measure each construct. Secondly, the measurement properties of all identified tests per physiological construct were evaluated with the ultimate purpose of identifying tests with strongest level of evidence per construct. Methods: The review was conducted in two stages. In all stages, electronic databases of EBSCOhost, Medline and Scopus were searched for full-text articles. Stage 1 included studies examining physiological characteristics in rugby. Stage 2 included studies evaluating measurement properties of all tests identified in Stage 1 either in rugby or related sports such as Australian Rules football and Soccer. Two independent reviewers screened relevant articles from titles and abstracts for both stages. Results: Seventy studies met the inclusion criteria for Stage 1. The studies described 63 tests assessing speed (8), agility/change of direction speed (7), upper-body muscular endurance (8), upper-body muscular power (6), upperbody muscular strength (5), anaerobic endurance (4), maximal aerobic power (4), lower-body muscular power (3), prolonged high-intensity intermittent running ability/endurance (5), lower-body muscular strength (5), repeated high-intensity exercise performance (3), repeated-sprint ability (2), repeated-effort ability (1), maximal aerobic speed (1) and abdominal endurance (1). Stage 2 identified 20 studies describing measurement properties of 21 different tests. Only moderate evidence was found for the reliability of the 30-15 Intermittent Fitness. There was limited evidence found for the reliability and/or validity of 5 m, 10 m, 20 m speed tests, 505 test, modified 505 test, L run test, Sergeant Jump test and bench press repetitions-to-fatigue tests. There was no information from high-quality studies on the measurement properties of all the other tests identified in stage 1. Conclusion: A number of physiological characteristics are evaluated in rugby. Each physiological construct has multiple tests for measurement. However, there is paucity of information on measurement properties from high-quality studies for the tests. This raises questions about the usefulness and applicability of these tests in rugby and creates a need for high-quality future studies evaluating measurement properties of these physiological tests.

Objective: Transfer of motor skills is the ultimate goal of motor training in rehabilitation practice. In children with Developmental Coordination Disorder (DCD), very little is known about how skills are transferred from training situations to real life contexts. In this study we examined the influence of two types of practice on transfer of motor skills acquired in a virtual reality (VR) environment. Method: One hundred and eleven children with DCD and their typically developing (TD) peers, aged 6–10 years (M = 8.0 SD = 1.0) were randomly assigned to either variable (n = 56) or repetitive practice (n = 55). Participants in the repetitive practice played the same exergame (ski slalom) twice weekly for 20 minutes, over a period of 5 weeks, while those in the variable group played 10 different games. Motor skills such as balance tasks (hopping), running and agility tasks, ball skills and functional activities were evaluated before and after 5 weeks of training. Results: ANOVA repeated measures indicated that both DCD and TD children demonstrated transfer effects to real life skills with identical and non-identical elements at exactly the same rate, irrespective of the type of practice they were assigned to. Conclusion: Based on these findings, we conclude that motor skills acquired in the VR environment, transfers to real world contexts in similar proportions for both TD and DCD children. The type of practice adopted does not seem to influence children’s ability to transfer skills acquired in an exergame to life situations but the number of identical elements does.

Purpose:Constraint-induced movement therapy (CIMT) is a promising technique for the recovery of upper extremity movement in chronic stroke patients. However, the effectiveness of its use in acute ischemia has not been confirmed. Myelin-associated inhibitors, which have upregulated functions in tissues affected by acute focal infarction, limit axonal regeneration via activation of the Rho–Rho-associated protein kinase (ROCK) pathway. The present study examined whether early CIMT combined with the ROCK inhibitor fasudil promotes motor recovery after acute ischemic stroke.Materials and Methods:Rats were trained to perform the skilled-reach test and then subjected to middle cerebral artery occlusion (MCAO), producing a stroke affecting the preferred forelimb. Rats were assigned to one of four groups (N= 6/group): (nontreated) Control, CIMT, Fasudil, or CIMT+fasudil. CIMT and/or intraperitoneal infusion of fasudil were initiated 1 day postMCAO. Skilled reach and foot fault test data were collected once before and repeatedly over 4 weeks after the operation. Infarct volumes were calculated.Results:All four groups showed similar forelimb impairment before treatment. The performance of CIMT alone group was similar to that of controls on both tests. Fasudil alone facilitated recovery in the foot-fault test, but not in the skilled-reach test. Rats in the CIMT+fasudil group demonstrated enhanced recovery in both tests, including better performance over time than the Fasudil group on the foot-fault test. Infarct size did not differ significantly between the groups.Conclusions:Early CIMT promotes motor recovery after acute ischemic stroke when it is administered with fasudil pharmacotherapy, but not without it.
