Comparisons of Mood States Associated With Outcomes Achieved by Female and Male Athletes in High-Level Judo and Brazilian Jiu-Jitsu Championships: Psychological Factors Associated With the Probability of Success.

ABSTRACT: Brandt, R, Bevilacqua, GG, Crocetta, TB, Monteiro, CBdM, Guarnieri, R, Hobold, E, Flores, LJF, Miarka, B, and Andrade, A. Comparisons of mood states associated with outcomes achieved by female and male athletes in high-level judo and Brazilian jiu-jitsu championships: psychological factors associated with the probability of success. J Strength Cond Res 35(9): 2518-2524, 2019-Moods can be used to predict the performance of athletes in various sports; accordingly, we selected the Brunel Mood Scale (BRUMS) to evaluate mood states of high-level judo and Brazilian jiu-jitsu (BJJ) athletes. The aims of this study were (a) to compare the mood states of high-level female and male athletes in BJJ and judo championships in relation to their performance outcomes and (b) to verify associations between psychological factors and performance in estimating their probability of success. The subjects were 173 grappling athletes (judo, n = 85 and BJJ, n = 88), separated into male (n = 129, 40 winners and 89 nonwinners) and female (n = 44, 23 winners and 21 nonwinners) groups. Each subject's mood state was assessed 60 minutes before the first match using the BRUMS (tension, depression, anger, vigor, fatigue, and mental confusion dimensions). Descriptive and inferential statistics (including logistic regression and variance analysis) were used to evaluate relations between mood states and performance (i.e., winning/losing), with p ≤ 0.05. Analysis showed significant differences between male and female athletes in vigor and fatigue, and differences between male judo and male BJJ athletes in tension, vigor, confusion, and fatigue. Female judo and female BJJ athletes showed significant differences in depression and vigor. Logistic regression revealed that higher levels of anger and tension increased athletes' chances of performing well in a match by 23 and 13%, respectively. In addition, lower levels of depression increased athletes' chances of better performance by up to 32%. Overall, we observed a significant relationship between mood state and sports performance. Thus, coaching staff and athletes should monitor athletes' mood states before competitions to ensure that they are in optimal condition to perform and use psychological interventions to support judo and BJJ preparation.

Use of Augmented Reality with a Motion-Controlled Game Utilizing Alphabet Letters and Numbers to Improve Performance and Reaction Time Skills for People with Autism Spectrum Disorder.

Augmented reality (AR) uses the real-world setting but enables a person to interact with virtual objects. In this study, we aimed to explore the use of alphabet letter and number in an AR task and its influence in reaction time in a population with autism spectrum disorders (ASD) compared with the performance of typical developing (TD) controls. We evaluated reaction time before and after AR tasks that consisted of identifying correct numbers and alphabet letters in 48 people with ASD and 48 with TD controls. Results indicate that total points for TD group were higher (M = 86.4 and M = 79.0) when compared with the ASD group (M = 54.5 and M = 51.5) for alphabet letters and numbers, respectively. Moreover, in analysis of reaction time results, only the ASD group showed an improvement in performance after the practice of an AR task. The control group was faster before (M = 553.7) and after (M = 560.5) when compared with the ASD group (M = 2616.0 and M = 2374.6, respectively). Despite the need for further studies, our results support that there is potential for clinical use of an AR task-based intervention for people with ASD.

Systematic Review of the Main Motor Scales for Clinical Assessment of Individuals with down Syndrome.

Objective: The aim of the present review was to identify the motor scales currently used to assess individuals with Down Syndrome (DS).Method: PubMed, WOS and BVS databases were systematically searched to identify the most relevant published studies that used motor scales in the evaluation of individuals with DS.Results: Of the 99 studies that met the eligibility criteria in this process, 20 experimental and observational studies were found to fully meet the eligibility criteria.Conclusion: We identified several motor scales including the Alberta Infant Motor Scale (AIMS), Test of Infant Motor Performance (TIMP), BAYLEY, Peabody Gross Motor Scale (PGMS-PDMS-GM), Gross Motor Function Measure (GMFM), Movement Assessment Battery for Children (MABC) and Pediatric Evaluation of Disability Inventory (PEDI).

Test-Retest Reliability and Clinical Feasibility of a Motion-Controlled Game to Enhance the Literacy and Numeracy Skills of Young Individuals with Intellectual Disability.

Games using motion capture from web cameras have become increasingly popular. However, there are no games specifically designed to teach literacy to individuals with intellectual disabilities (ID). The aim of this study was to investigate the feasibility of introducing young individuals with ID to a new augmented reality game, the MoviLetrando, and establish its test-retest reliability to determine its usefulness in teaching the alphabet and motor control skills. The performance of a sample of 88 ID participants (52 males, 36 females, mean ± standard deviation age, 11.2 ± 2.6 years) was measured on two different testing sessions. Five dependent variables (total points, number of correct vowels/numbers, number of mistakes, number of omissions, and average time to reach symbols) were used for data analysis. The intraclass correlation coefficient (ICC), standard error of measurement (SEM), Cronbach's alpha, and Bland-Altman plots were used to estimate the test-retest reliability and measurement precision. Feasibility was assessed by examining recruitment, adherence, and acceptability in both phases of the game. The dependent variables identified in the MoviLetrando demonstrated an ICC of 0.44 to 0.82, suggesting acceptable/good test-retest reliability, respectively. The internal consistency was satisfactory. The small SEM, as well as the narrow width of the 95 percent limits of agreement in the Bland-Altman plots, implied that measurements of these dependent variables were precise and accurate on both the occasions. Excellent test-retest reliability for performance measurement was demonstrated in the ID participants, indicating that the MoviLetrando could be used as an outcome measure for this population.

Assistive technology for communication of older adults: a systematic review.

OBJECTIVE: Describe the use of assistive technology to enhance communication opportunities for older adults. METHODS: A systematic review was conducted in two databases, PubMed and Web of Science, by using two different searches in each. The search was limited to original articles, in English language, including people aged 60 years and older that used any type of assistive technology for communication. The articles found in the initial search were filtered by title, abstracts and the remaining articles were fully read. RESULTS: Eighteen studies were included in this review after the reading of full-texts. Most of the studies included apparently healthy participants with communication limitations due to aging related changes and the others included people with some pathology that prevent them from normal communication. CONCLUSION: Four categories of assistive technology were identified: assistive technology for people with speech problems; robot or videoconferencing systems; Information and Communication Technologies and, other types of assistive technology for communication, such as hearing aids and scrapbooks. Assistive technology for communication of older adults is not only used by people with disabilities that prevent them from usual communication. They are mostly for older adults without a pathological communication problem.

The Clinical Utility of Virtual Reality in Neurorehabilitation: A Systematic Review.

BACKGROUND: Virtual reality (VR) experiences (through games and virtual environments) are increasingly being used in physical, cognitive, and psychological interventions. However, the impact of VR as an approach to rehabilitation is not fully understood, and its advantages over traditional rehabilitation techniques are yet to be established. METHOD: We present a systematic review which was conducted according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). During February and March of 2018, we conducted searches on PubMed (Medline), Virtual Health Library Search Portal databases (BVS), Web of Science (WOS), and Embase for all VR-related publications in the past 4 years (2015, 2016, 2017, and 2018). The keywords used in the search were "neurorehabilitation" AND "Virtual Reality" AND "devices." RESULTS: We summarize the literature which highlights that a range of effective VR approaches are available. Studies identified were conducted with poststroke patients, patients with cerebral palsy, spinal cord injuries, and other pathologies. Healthy populations have been used in the development and testing of VR approaches meant to be used in the future by people with neurological disorders. A range of benefits were associated with VR interventions, including improvement in motor functions, greater community participation, and improved psychological and cognitive function. CONCLUSIONS: The results from this review provide support for the use of VR as part of a neurorehabilitation program in maximizing recovery.

Instruments for augmentative and alternative communication for children with autism spectrum disorder: a systematic review.

New technologies designed to improve the communication of autistic children can also help to promote interaction processes and cognitive and social development. The aim of this study was to analyze the instruments used to improve the communication skills of children with autism spectrum disorder. We searched the PubMed and Web of Science databases using the descriptors "autism", "Asperger", "education", "children" and "assistive technology" and selected articles that met the following inclusion criteria: (i) original research; (ii) written in English; (iii) based on participants with a primary diagnosis of autism spectrum disorder; and (iv) tested an instrument designed to promote communication in children with autism spectrum disorder. Our search retrieved 811 articles, of which 34 met the inclusion criteria. Data on 26 instruments were extracted, and the measurement properties of the instruments were combined with information about their outcomes and presentation. The most commonly used interventions were the Treatment and Education of Autistic and Related Communication Handicapped Children program and the Picture Exchange Communication System. The Treatment and Education of Autistic and Related Communication Handicapped Children program was shown to produce improvements in the communication skills, socialization and self-care skills of children with autism spectrum disorder. The Picture Exchange Communication System produced inconsistent results. The results of the identified studies confirm the significant importance of these instruments in improving the communicative process of autistic children.

A didactic approach to presenting verbal and visual information to children participating in research protocols: the comic book informed assent.

OBJECTIVE: When children participate in research protocols, consent (by a parent or legal guardian) and assent (by the children) must be given. Understanding research protocols can be challenging for an adult and even more difficult for a child. The aim of this study was to describe the development of a comic book created to facilitate children's understanding of informed assent with clear and simple language. METHODS: Five researchers with scores above seven according to the Fehring criteria developed the comic book, avoiding the use of technical terminology. Twenty children between 7 and 12 years old, and enrolled in a larger study, responded using a Likert scale and questions about the clarity of texts and illustrations. The final version met National Health System Resolutions (Resoluções do Conselho Nacional da Saúde - CNS n° 196/1996 and 466/2012). RESULTS: The comic book assent presents a short story containing information about a real study: the invitation to participate, objectives, methods, instruments, procedures, risks, benefits, and the researchers' contact information. Most of the participants answered that they perceived the content of the text to be "Excellent" (40%) and "Very good" (40%), and the illustrations were perceived as "Excellent" (45%) and "Very good" (55%). CONCLUSION: The construction of a simple and clear model of informed assent is possible, and this model should be used in experiments with children.

Heart rate variability in individuals with Down syndrome - A systematic review and meta-analysis.

INTRODUCTION: Down syndrome (DS) results in many changes, including dysfunction in cardiac autonomic modulation. Heart rate variability (HRV) analysis evaluates the autonomic function and it is a predictor of adverse cardiovascular events. OBJECTIVE: To present results of a systematic review and a meta-analysis about heart rate variability in individuals with DS. METHOD: A systematic review was performed on PubMed, PubMed Central and Web of science databases. We included articles that exhibited all the terms: "Down Syndrome", "heart rate variability", "autonomic nervous system", "autonomic dysfunction" and "cardiac autonomic modulation". We conducted the meta-analysis to compare "DS" to "controls" during rest. Random effects models were used, as were appropriate tests for heterogeneity. RESULTS: From 271 studies, 13 were included in our review. These are conducted with volunteers from a wide age range, of either gender, and not taking medications. Meta-analysis displayed that there were no significant differences between the groups at rest, except the RMSSD, which revealed a significant (Z = -2.80, p = 0.005) main effect (Hedge's g = -0.55, 95% CI [-0.93; -0.16]), indicating difference in individuals with DS compared with controls. CONCLUSION: There is autonomic dysfunction in individuals with DS, which may or may not be expressed at rest, but it is usually demonstrated in an autonomic task. Meta-analysis specified that there was no significant alteration between DS and the controls during rest, except RMSSD index which was lower in DS than controls. PROSPERO: CRD42017068647.

Augmentative and alternative communication in children with Down's syndrome: a systematic review.

BACKGROUND: The use of technology to assist in the communication, socialization, language, and motor skills of children with Down's syndrome (DS) is required. The aim of this study was to analyse research findings regarding the different instruments of 'augmentative and alternative communication' used in children with Down's syndrome. METHODS: This is a systematic review of published articles available on PubMed, Web of Science, PsycInfo, and BVS using the following descriptors: assistive technology AND syndrome, assistive technology AND down syndrome, down syndrome AND augmentative and alternative communication. Studies published in English were selected if they met the following inclusion criteria: (1) study of children with a diagnosis of DS, and (2) assistive technology and/or augmentative and alternative communication analysis in this population. RESULTS: A total of 1087 articles were identified. Thirteen articles met the inclusion criteria. The instruments most used by the studies were speech-generating devices (SGDs) and the Picture Exchange Communication System (PECS). CONCLUSION: Twelve instruments that provided significant aid to the process of communication and socialization of children with DS were identified. These instruments increase the interaction between individuals among this population and their peers, contributing to their quality of life and self-esteem.

Achievement of Virtual and Real Objects Using a Short-Term Motor Learning Protocol in People with Duchenne Muscular Dystrophy: A Crossover Randomized Controlled Trial.

OBJECTIVE: To evaluate whether people with Duchenne muscular dystrophy (DMD) practicing a task in a virtual environment could improve performance given a similar task in a real environment, as well as distinguishing whether there is transference between performing the practice in virtual environment and then a real environment and vice versa. METHODS: Twenty-two people with DMD were evaluated and divided into two groups. The goal was to reach out and touch a red cube. Group A began with the real task and had to touch a real object, and Group B began with the virtual task and had to reach a virtual object using the Kinect system. RESULTS: ANOVA showed that all participants decreased the movement time from the first (M = 973 ms) to the last block of acquisition (M = 783 ms) in both virtual and real tasks and motor learning could be inferred by the short-term retention and transfer task (with increasing distance of the target). However, the evaluation of task performance demonstrated that the virtual task provided an inferior performance when compared to the real task in all phases of the study, and there was no effect for sequence. CONCLUSIONS: Both virtual and real tasks promoted improvement of performance in the acquisition phase, short-term retention, and transfer. However, there was no transference of learning between environments. In conclusion, it is recommended that the use of virtual environments for individuals with DMD needs to be considered carefully.

Functional performance comparison between real and virtual tasks in older adults: A cross-sectional study.

INTRODUCTION: Ageing is usually accompanied by deterioration of physical abilities, such as muscular strength, sensory sensitivity, and functional capacity, making chronic diseases, and the well-being of older adults new challenges to global public health. OBJECTIVE: The purpose of this study was to evaluate whether a task practiced in a virtual environment could promote better performance and enable transfer to the same task in a real environment. METHOD: The study evaluated 65 older adults of both genders, aged 60 to 82 years (M = 69.6, SD = 6.3). A timing coincident task was applied to measure the perceptual-motor ability to perform a motor response. The participants were divided into 2 groups: started in a real interface and started in a virtual interface. RESULTS: All subjects improved their performance during the practice, but improvement was not observed for the real interface, as the participants were near maximum performance from the beginning of the task. However, there was no transfer of performance from the virtual to real environment or vice versa. CONCLUSIONS: The virtual environment was shown to provide improvement of performance with a short-term motor learning protocol in a timing coincident task. This result suggests that the practice of tasks in a virtual environment seems to be a promising tool for the assessment and training of healthy older adults, even though there was no transfer of performance to a real environment.

Computer classes and games in virtual reality environment to reduce loneliness among students of an elderly reference center: Study protocol for a randomised cross-over design.

INTRODUCTION: Physical and mental changes associated with aging commonly lead to a decrease in communication capacity, reducing social interactions and increasing loneliness. Computer classes for older adults make significant contributions to social and cognitive aspects of aging. Games in a virtual reality (VR) environment stimulate the practice of communicative and cognitive skills and might also bring benefits to older adults. Furthermore, it might help to initiate their contact to the modern technology. The purpose of this study protocol is to evaluate the effects of practicing VR games during computer classes on the level of loneliness of students of an elderly reference center. METHODS AND ANALYSIS: This study will be a prospective longitudinal study with a randomised cross-over design, with subjects aged 50 years and older, of both genders, spontaneously enrolled in computer classes for beginners. Data collection will be done in 3 moments: moment 0 (T0) - at baseline; moment 1 (T1) - after 8 typical computer classes; and moment 2 (T2) - after 8 computer classes which include 15 minutes for practicing games in VR environment. A characterization questionnaire, the short version of the Short Social and Emotional Loneliness Scale for Adults (SELSA-S) and 3 games with VR (Random, MoviLetrando, and Reaction Time) will be used. For the intervention phase 4 other games will be used: Coincident Timing, Motor Skill Analyser, Labyrinth, and Fitts. The statistical analysis will compare the evolution in loneliness perception, performance, and reaction time during the practice of the games between the 3 moments of data collection. Performance and reaction time during the practice of the games will also be correlated to the loneliness perception. ETHICS AND DISSEMINATION: The protocol is approved by the host institution's ethics committee under the number 52305215.3.0000.0082. Results will be disseminated via peer-reviewed journal articles and conferences. This clinical trial is registered at ClinicalTrials.gov identifier: NCT02798081.
