O objetivo deste estudo foi identificar níveis de desempenho ocupacional e de qualidade de vida de indivíduos com deficiência visual e posterior análise de inter-relação entre os índices encontrados. Realizou-se um levantamento descritivo e de corte transversal, junto a pessoas com deficiência visual, de idade igual ou superior a 18 anos, inscritas para reabilitação em um serviço universitário, no período de agosto de 2011 a março de 2012. Para a coleta de dados foram utilizados três instrumentos aplicados por entrevista pela própria pesquisadora. O primeiro foi um questionário que permite obter os dados de identificação e perfil sócio-demográfico. O segundo foi o COPM que mensura a auto-percepção do sujeito em relação ao seu desempenho ocupacional e o terceiro foi o SF-36, instrumento que possibilita verificar a auto-percepção do sujeito em relação a sua qualidade de vida. Para análise dos dados foi construído banco de dados e realizado o tratamento estatístico. A amostra foi não probabilística constituída de acordo com os critérios de conveniência e composta de 23 sujeitos, sendo 74,0% com baixa visão, 52,2% do gênero feminino e a média de idade foi de 46,7 anos. A auto-percepção de desempenho ocupacional dos entrevistados foi baixa. Os resultados encontrados mostraram que a auto-percepção de desempenho e aspectos emocionais dos participantes com baixa-visão foram melhores do que os com cegueira. Verificou-se que quanto maior era o tempo de deficiência visual, pior era a avaliação do domínio dor. O domínio vitalidade apresentou relação estatisticamente significativa com os domínios estado geral de saúde, desempenho e satisfação, assim como o domínio saúde mental apresentou relação com estado geral de saúde, dor, desempenho e vitalidade. Os resultados mostram que quanto melhor era o aspecto emocional, maior também a influência positiva refletida nos aspectos físicos, funcionais e sociais dos participantes. O desempenho ocupacional e a qualidade de vida são condições que podem ser trabalhadas em programa de reabilitação para pessoas com deficiência visual por meio de equipe interdisciplinar / Abstract: People with visual disabilities are oftentimes faced with difficulties regarding the social, economic and functional areas, which may impair their level of independence and self-esteem, affecting therefore their quality of life. The purpose of this study was to identify levels of occupational performance and quality of life of individuals with visual disabilities and subsequent analysis of the interrelationship among the indexes found. A descriptive and cross-sectional study was conducted, with a sample group of people with visual disabilities, aged 18 years old and over, which were enrolled on rehabilitation in a university center, from August 2011 to March 2012. For data collection three instruments were applied through interviews by the researcher. The first was a questionnaire used in order to obtain identification data and social-demographic profile. The second was the COPM which measures one's self-perception of occupational performance and the third was the SF-36, an instrument that allows verifying the self-perception of quality of life. For data analysis a database was constructed and statistical analysis was performed. Group sample was classified under a non-probability sampling (convenience) and comprised 23 individuals, 74.0% with low vision, 52.2% were female and the mean age was 46.7 years. Self-perception of occupational performance by the interviewees was low. Results showed that self-perception of performance and emotion aspects of the participants with low vision were better than those with blindness. It was verified that the larger the time of visual impairment, the worse the evaluation of the pain domain. The vitality domain showed a statistically significant relationship with the domains general health, performance and satisfaction, whereas the mental health domain was related to general health, pain, vitality and performance. The results showed that the better the emotional aspect, the greater the positive influence reflected in physical, functional and social aspects of the participants. Occupational performance and quality of life are conditions that may be employed in a rehabilitation program for people with visual disabilities through an interdisciplinary team / Mestrado / Interdisciplinaridade e Reabilitação / Mestra em Saúde, Interdisciplinaridade e Reabilitação

Simultaneously listening to music whilst doing other tasks has become more common with the development of mobile technology and the rise of streaming platforms, but what affect does listening to music have on task performance? There have been several theories on this both advocating for and against the effects of music. This study has two primary questions to answer. Does background noise (condition 1: no music, condition 2: music with words, condition 3: same music without words) influence reading comprehension, and does how well individuals perform on complex tasks correlate with individual differences particularly their ability to media multitask and their boredom proneness. The findings are generally in-line with the consensus of prior research that music does have a negative impact on complex tasks when compared to performing them without auditory stimuli. Although there are differences depending on what stimuli is used. A correlation was found that has not been extensively studied by prior research to my knowledge. It pertains to the relationship of media multitasking and boredom proneness. It seems like the higher an individual’s MM score is the lower their BP score will be, on average. What implications this might have for the larger attention research field needs to be further explored before any inference can be made. The ANOVA and regression results for the other variables showed no significant correlations. / Att lyssna på musik samtidigt som man utför andra uppgifter har blivit allt vanligare med utvecklingen av mobil teknik och uppkomsten av streamingplattformar, men vilken påverkan har egentligen musiklyssnande på uppgiftprestanda. Det har funnits flera teorier om detta som förespråkande för och emot effekterna av musik. Denna studie har primärt två frågor att svara på. Påverkar bakgrundsljud (villkor 1: ingen musik, villkor 2: musik med ord, villkor 3: samma musik utan ord) läsförståelsen, och finns det ett samband mellan hur bra en individ utför en komplex uppgift, och individuella skillnader, särskilt förmågan för "media multitasking" och deras "boredom proneness". Resultaten är allmänt i linje med konsensusen från tidigare forskning att musik har en negativ inverkan på komplexa uppgifter jämfört med att utföra dem utan auditivt stimuli. Även om det finns skillnader i inverkan beroende på vilka stimuli som används. En korrelation hittades som inte har undersökts noggrant genom tidigare forskning, enligt min vetskap. Det avser förhållandet mellan "media multitasking" och "boredom proneness". Det verkar som att ju högre en individs MM-poäng är desto lägre blir deras BP-poäng. Vilka konsekvenser detta kan ha för forskningsfältet i stort är svårt att säga och måste undersökas ytterligare innan någon slutsats kan göras. Resultaten från utförd ANOVA och regressionsanalys påvisade inga andra signifikanta korrelationer mellan de andra variablerna i insamlade data.

Sufficient rest breaks are needed for optimal performance in traditional workplaces, but it is unclear how working with a loosely structured work schedule impacts recovery. Students have temporal flexibility and serve as a good proxy for all groups who work unstructured work schedules. Since most students and employees use the weekend to recover, this study investigated the relationship between recovery experiences (i.e., psychological detachment, relaxation, and mastery) over the weekend and the state of being recovered on the following Monday. Further, the relationship between the state of being recovered on Monday and weekday performance indicators (i.e., task performance and personal initiative) was investigated. Data was collected over three consecutive weeks from a cohort of first-year university students (N = 106) using a quantitative diary study design. This study administered seven surveys (i.e., a personal data survey once, a pre-weekend survey three times, and a postweekend survey three times). After three weeks, 66 participants (N = 66) had completed all the surveys at the person level, yielding 148 matched observations at the week-level. Multilevel modelling showed that weekend relaxation positively predicted the state of being recovered on Monday. Weekend psychological detachment and weekend mastery experiences did not predict the state of being recovered on Monday, and the state of being recovered did not predict weekly personal initiative or weekly task performance. The theoretical and practical implications of this study are presented, as are limitations and suggestions for future research.

<p dir="ltr">Task performance is considered an important emphasis in the world of Human-Computer Interaction (HCI). With the emergence of advanced technologies such as Virtual Reality (VR), it is important to understand how individuals are able to utilize this tool for productive task performance. Researchers are continuously exploring how to enhance human performance in a digital space (Wang & Jung, 2011). Prior research has demonstrated the role of integrating haptic feedback into a visual interface, with potential benefits in task performance, as well as increased experiences of presence and awareness while completing HCI tasks. Several research studies have been carried out to investigate ways to optimize human performance and richly uncover factors that affect human performance negatively and positively (Asan et al., 2015). Typically, in a VR setting, three primary senses are engaged: visual, auditory, and tactile (haptic). However, there is a gap in the literature regarding how the availability and intensity of haptic feedback through VR controllers affect users during task performance. This research study seeks to understand the cognitive performance of users in VR when exposed to varying levels of haptic feedback via the VR controllers. Results from this research reveal that participants perceived their performance to be higher and frustration to be lower when they were exposed to moderate and consistent availability and intensity of haptic feedback. To enhance VR’s immersion for users, it is essential to comprehend how to engage the human senses to optimize cognitive performance. Overall, the impact of this research study is to add to an existing body of literature in the domain of haptic feedback for extended reality-based experiences. </p>

Yes / The headscarf conceals hair and other external features of a head (such as the ears). It therefore may have implications for the way in which such faces are perceived. Images of faces with hair (H) or alternatively, covered by a headscarf (HS) were used in three experiments. In Experiment 1 participants saw both H and HS faces in a yes/no recognition task in which the external features either remained the same between learning and test (Same) or switched (Switch). Performance was similar for H and HS faces in both the Same and Switch condition, but in the Switch condition it dropped substantially compared to the Same condition. This implies that the mere presence of the headscarf does not reduce performance, rather, the change between the type of external feature (hair or headscarf) causes the drop in performance. In Experiment 2, which used eye-tracking methodology, it was found that almost all fixations were to internal regions, and that there was no difference in the proportion of fixations to external features between the Same and Switch conditions, implying that the headscarf influenced processing by virtue of extrafoveal viewing. In Experiment 3, similarity ratings of the internal features of pairs of HS faces were higher than pairs of H faces, confirming that the internal and external features of a face are perceived as a whole rather than as separate components. / The Educational Charity of the Federation of Ophthalmic and Dispensing Opticians.

Os objetivos deste trabalho foram desenvolver um dispositivo apontador, com as mesmas funções de um mouse, controlado pelo movimento da cabeça, e comparar a eficiência do dispositivo proposto, utilizando o controle do cursor do computador no modo absoluto e relativo (joystick), operado por dez indivíduos tetraplégicos e por dez indivíduos sem acometimento neuromuscular. A maioria dos parâmetros estudados apresentou diferença significativa, entre as situações de controle absoluto e relativo, para os indivíduos de ambos os grupos, evidenciando que os parâmetros medidos no modo absoluto foram melhores que os medidos no modo relativo. O dispositivo apontador emula adequadamente as funções de deslocamento do cursor, mostrando que o modo de controle absoluto é mais eficiente que o modo de controle relativo / The objectives of this study were to develop a head controlled pointer device with mouse functions and compare its performance when operated in absolute versus relative (joystick like) modes by ten quadriplegic subjects and ten people without neuromuscular impairment. The device was composed of a video camera, a computer program and a reflective paper target attached to a cap which was then placed on the user´s head. Most of the measured parameters revealed a significant difference between the control modes, favouring the absolute one, for both studied groups. The developed head pointer adequately emulates the computer cursor displacement, with the absolute control mode being functionally more efficient than the relative control mode in this study.

Objetivo: Avaliar a responsividade da escala de avaliação funcional para pacientes com distrofia muscular de Duchenne (DMD), domínio 1 - sentar e levantar da cadeira (FES-DMD-D1). Método: Estudo observacional, retrospectivo e longitudinal (seguimento por um ano). Foi estudada, utilizando o software FES-DMD-DATA, uma amostra de 150 avaliações da atividade de sentar e levantar da cadeira, a partir de um banco de imagens com filmes de 30 crianças com DMD, executando atividades funcionais, avaliadas a cada três meses, em um período de um ano. A avaliação da FES-DMD-D1 foi aplicada por fisioterapeuta treinado, considerando os escores das fases de flexão, de contato e de extensão da atividade de sentar na cadeira e, das fases de flexão, de transferência e de extensão da atividade de levantar da cadeira. Para avaliar a responsividade da FES-DMD-D1 foram analisadas as avaliações dos períodos de seguimento de três, seis, nove e doze meses, por meio do tamanho do efeito (TE) e da média de resposta padronizada (MRP). Resultados: A responsividade da atividade de sentar na cadeira foi considerada de pequena a moderada nas avaliações a cada três meses (TE de 0,22 a 0,49 e MRP de 0,32 a 0,54), de pequena a moderada a cada seis meses (TE de 0,50 a 0,61 e MRP de 0,41 a 0,61), de pequena a grande a cada nove meses (TE de 0,69 a 1,11 e MRP de 0,49 a 0,79) e grande no período de um ano (TE de 1,07 e MRP de 0,80). Na atividade de levantar da cadeira, a responsividade foi pequena a cada três meses (TE de 0,21 a 0,35 e MRP de 0,28 a 0,45), de pequena a grande a cada seis meses (TE de 0,45 a 0,62 e MRP de 0,50 a 0,96), de moderada a grande a cada nove meses (TE de 0,76 a 0,89 e MRP de 0,74 a 1,47) e grande em um ano (TE de 1,28 e MRP de 1,24). Conclusão: A FES-DMD-D1 mostrou responsividade de moderada a grande, aumentando gradativamente nos intervalos de seis, nove e doze meses. Dessa forma, é indicado o uso da FES-DMD-D1 a partir de seis meses / Objective: To evaluate the responsiveness of the functional evaluation scale for patients with Duchenne muscular dystrophy (DMD) - domain 1: sitting and standing from the chair (FES-DMD-D1). Method: Observational, retrospective and longitudinal study with one year follow-up. A sample of 150 evaluations of sitting and rising from the chair was studied, using the FES-DMD-DATA software, from a bank of images of 30 children with DMD performing functional activities, evaluated every three months in a period of one year. FES-DMD-D1, which explores the scores of the phases of flexion, contact, extension of the activity of sitting on the chair, and of the phases of flexion, transference, extension of the activity of rising from the chair was applied by a trained physiotherapist. To evaluate the responsiveness of FES-DMD-D1 we considered the follow-up evaluations after three, six, nine and twelve months. The analysis used the effect size (ES) and standardized response mean (SRM). Results: The responsiveness of sitting on the chair was considered low to moderate in evaluations with three months intervals (ES from 0.22 to 0.49 and SRM from 0.32 to 0.54), low to moderate with six months intervals (ES from 0.50 to 0.61 and SRM from 0.41 to 0.61), low to high in nine months intervals (ES from 0.69 to 1.11 and SRM from 0.49 to 0.79) and high in the reassessment after one year (ES from 1.07 and SRM from 0.80). The responsiveness of the rising from the chair was low in three months (ES from 0.21 to 0.35 and SRM from 0.28 to 0.45), from low to high in six months (ES from 0.45 to 0.62 and SRM from 0.50 to 0.96), moderate to high in nine months (ES from 0.76 to 0.89 and SRM from 0.74 to 1.47) and high in a year (ES from 1.28 and SRM from 1.24). Conclusion: FES-DMD-D1 showed moderate to high responsiveness, gradually increasing for intervals of six, nine and twelve months. Thus, the use of FES-DMD-D1 is indicated from six months

A progressão da distrofia muscular de Duchenne (DMD) resulta no surgimento de múltiplas e variadas sinergias para compensar a fraqueza muscular e para lidar com as demandas de tarefas funcionais, como por exemplo, a marcha. Alguns instrumentos de avaliação funcional para pessoas com DMD permite a análise subjetiva (descrição) e objetiva (escore) sem levar em consideração os movimentos compensatórios. Por esta razão, os médicos e os fisioterapeutas enfrentam dificuldades na avaliação clínica e tomada de decisão. Este estudo teve como objetivo elaborar o domínio marcha da Escala de Avaliação Funcional para DMD / Functional Evaluation Scale (FES-DMD-D4), testar sua confiabilidade intraexaminador e interexaminadores e sua relação com a idade, escala Vignos e tempo de desempenho da marcha. Uma amostra de 120 vídeos da marcha de 30 crianças com DMD foi analisada. Os movimentos detectados foram classificados considerando suas características cinesiológicos e padrões de compensações. FES-DMD-D4 foi criada e submetida à avaliação de 10 especialistas. Após a incorporação das sugestões propostas, a escala foi utilizada no total da amostra para avaliação por três examinadores. Foi calculada a confiabilidade intraexaminador e interexaminadores utilizando ICC. As relações entre o FES-DMD-D4 e a idade, a escala Vignos e o tempo de desempenho foram testadas com teste de correlação de Spearman (p < 0,05). A FES-DMD-D4 foi composta por três fases, e 14 itens. Coeficientes de correlação intraclasse variaram de aceitável (0,79) a excelente (0,98). A pontuação total da FES-DMD-D4 correlacionou-se com a idade e o tempo de desempenho, mas não com a escala Vignos / The progression of Duchenne Muscular Dystrophy (DMD) results in the emergence of multiple and varied synergies to compensate muscle weakness and to deal with the demands of functional tasks, such as gait. Few functional evaluation instruments for people with DMD allows for subjective analysis (description) and objective (score) without taking into account the compensatory movements. For this reason, clinicians and physiotherapists face difficulties in clinical assessment and decision-making. This study aimed to elaborate the gait domain of the Functional Evaluation Scale for DMD, gait domain (FES-DMD-D4) and to test its reliability intraexaminer and interexaminers and its relationship with age, Vignos score and timed motor performance. A sample of 120 gait videos of 30 children with DMD was analyzed. The detected movements were classified, considering the kinesiological characteristics of the compensation movements. FES-DMD-D4 was created and submitted to the review of 10 experts. After the incorporation of the suggestions proposed by the experts, the scale was used to analyse a total sample by 3 examiners. The reliability intraexaminer and interexaminers was calculated using ICC. The relationships between FES-DMD-D4 and age, Vignos score and timed motor performance was tested with Spearman correlation test (p < 0.05). The FES-DMD-D4 was composed of 3 phases, and 14 items. Intraclass correlation coefficients ranged from acceptable (0.79) to excellent (0.98). The scores on FES-DMD-D4 correlated to age and timed motor performance, but not to Vignos score
