Due to that, the upper limb motor control is impaired even on single task (isolated manual task) and dual task (manual task and posture control). Because these sort of tasks are performed during activities of daily living, the role of asymmetry on those task must be clarified to elucidate the effects of disease on PD functionality and thus guide the therapists choose more effective interventions. Among strategies of intervention on PD motor impairments, two strategies that deserve special attention are the instruction of external focus of attention and mirror therapy (MT). Both interventions might be potentially effective to facilitate motor learning. Aims: to assess the role of PD asymmetry on upper limbs motor control and postural control in conditions of single versus dual task; and tasks with attentional focus with instructions versus external focus as well as to verify the effect of MT on upper limbs motor control more affected on postural control of PD patients. Methods: Twenty PD patients were submitted to assessments on: Upper Limb motor control (kinematic analysis) and postural control (kinetics analysis), in single and dual task conditions, with and without external focus of attention. Posteriorly, the subjects were distributed in two different groups: GI1 and GI2. The MT protocol consisted in a unilateral home therapy on less affected upper limb, performed 30 minutes a day, five days a week, during 6 consecutives weeks. To assist the subjects of GI1, they performed this protocol using a visual feedback (mirror therapy). Both groups were assessed before and after therapy protocol. Results: performance was not different between upper limbs and single and dual tasks, both in single and in dual task. After protocol period, both groups showed improvements on kinematic outcomes (manual dexterity, movement frequency of the hand, hesitation and task performance time improvements, independent of the sort of focus of attention that was used). Conclusion: Manual task is not affected by PD asymmetry on single and dual task. The external focus of attention was not effective to improve the task performance in PD patients, and it is not recommended to be performed during dynamic tasks. The therapy protocol with or without visual feedback promotes extended benefits on execution and planning of manual task of more affected upper limb independently of focus of attention, but it is not able to decrease the functional and motor impairments neither improve postural control. Therefore MT seems to be equally effective on manual tasks benefits, however more studies are necessary to confirm this efficacy. / Introdução: a doença de Parkinson (DP) tem o início assimétrico dos sintomas motores e afeta o processamento e a integração das informações proprioceptivas, comprometendo o controle motor dos membros superiores tanto em tarefa singular (tarefa manual isolada) quanto em tarefa dupla (tarefa manual e controle postural). Por estas tarefas serem frequentemente exigidas nas atividades de vida diária, esclarecimentos quanto ao papel da assimetria da doença nessas tarefas podem elucidar sobre os efeitos da doença na funcionalidade dos pacientes e nortear a decisão sobre estratégias de intervenção mais pertinentes. Dentre as estratégias de intervenção para esses comprometimentos encontram-se a instrução de foco de ação externo e a terapia do espelho (TE). Ambas as intervenções podem ser potencialmente eficazes na DP por facilitar a aprendizagem motora. Objetivos: avaliar o papel da assimetria da doença no controle dos membros superiores e do controle postural nas condições de tarefa singular versus dupla e de tarefa com instrução de foco de atenção livre versus foco externo, assim como verificar o efeito da TE no controle motor do membro superior afetado e no controle postural de pacientes com DP. Método: 20 pacientes foram avaliados quanto ao controle dos membros superiores (análise cinemática) e ao controle postural (análise cinética), nas condições de tarefa singular e dupla, foco de atenção livre e externo. Posteriormente, os pacientes foram distribuídos nos grupos GI1 e GI2 e realizaram a intervenção que consistiu de treino unilateral do membro superior menos afetado, com duração de 30 minutos diários, 5 dias consecutivos na semana, durante 6 semanas, em domicílio. Na intervenção somente o GI1 utilizou o feedback visual - TE. Os grupos foram avaliados pré- e pós-intervenção. Resultados: o desempenho não diferiu entre os membros superiores e entre as condições de tarefa singular e dupla. O foco de atenção externo reduziu o desempenho da tarefa manual, tanto na tarefa singular quanto na dupla. Após o período de intervenção, ambos os grupos melhoraram o desempenho nas variáveis cinemáticas – aumentaram a destreza manual e a frequência de movimento da mão, diminuíram a hesitação na realização do movimento e o tempo para realizar a tarefa, independente do foco de atenção empregado. Conclusão: a assimetria da doença não interfere no desempenho da tarefa manual nas condições de tarefa singular e dupla. O foco de atenção externo não foi eficaz em melhorar o desempenho da tarefa manual em pacientes com DP, não devendo ser utilizado em tarefas dinâmicas. A intervenção, com ou sem feedback visual, melhora a execução e o planejamento da tarefa manual do membro superior afetado independente do foco atencional empregado, mas não é capaz de reduzir o comprometimento funcional e motor, nem de melhorar o desempenho do controle postural. Portanto, a TE parece ser igualmente eficaz na melhora do desempenho da tarefa manual, porém, mais estudos são necessários para afirmar sua efetividade. / CNPq: 157894/2013-4

Resumo: Durante o período de escolarização, algumas crianças podem apresentar dificuldades na coordenação motora, principalmente em habilidades manuais, e podem ser identificadas como tendo Transtorno do Desenvolvimento da Coordenação (TDC). Existem evidências na literatura que déficits nos mecanismos de controle e precisão para produção de força/torque dos dedos estejam associados às dificuldades motoras nessas crianças. Assim, como a produção de força/torque é essencial para inúmeras atividades da vida diária, o presente estudo teve como objetivo principal investigar o efeito da prática no desempenho de crianças com TDC e com desenvolvimento típico (DT). Participaram do estudo, 24 crianças com idade entre 9 e 10 anos. A tarefa praticada foi a de preensão digital em torque com feedback visual. As crianças foram incentivadas a manter, durante 15 segundos, de forma contínua e constante, 25% do torque voluntário máximo. A prática foi feita durante cinco dias consecutivos, com realização de 15 tentativas por dia. Após a prática com feedback visual, as crianças foram incentivadas a realizar cinco tentativas na condição sem feedback visual. Nestas tentativas, o feedback visual era removido após 5 segundos do início da tentativa. Os resultados demonstraram que nos cinco dias de prática as crianças com DT foram consistentemente mais precisas em manter o controle de torque do que as crianças com TDC. As crianças de ambos os grupos melhoraram o desempenho no decorrer das sessões de prática evidenciado pela redução do coeficiente de variação e da dispersão média do erro...(Resumo completo, clicar acesso eletrônico abaixo) / Abstract: During the first years in school, children can show motor coordination difficulties mainly in manual skills and they can be identified as shown Developmental Coordination Disorder (DCD). There is evidence from the literature that deficits in the mechanisms of accuracy and control in the finger production of strength/torque are associated with the motor difficulties of these children. The production of strength/torque is essential for a large number of daily activities so that the effect of practice of grip torque among DCD children and those shown typical development (DT) was the main objective of the present study. Participants were 24 children aged between 9 and 10 years. Children were asked to keep control of torque in a continuous and constant way with visual feedback (25% of maximum voluntary torque) during a period of 15 seconds. Practice was given during five consecutive days with 15 trials per day. After the practice with visual feedback, children were asked to perform five trials without visual feedback. In these trials, feedback was removed five seconds after the start of the trial. The results showed during the five days of practice that children with DT were consistently more accurate in keeping torque control than those with DCD. Children from both groups improved the level of performance as practice took place shown reduction of the coefficient of variation and of error (RMS). In relation to the trials without visual feedback, DCD children were not able to perform at the same level as they did when visual feedback was available...(Complete abstract, click electronic access below) / Orientador: Ana Maria Pellegrini / Coorientador: Cynthia Y.

The joint references generated by this mapping are utilized for dynamic control in joint space. Thus, the end-effector position is, in fact, controlled indirectly, in open-loop, and the accuracy of grip position control directly depends on the accuracy of the available kinematic model. In this report, a new scheme for redundant manipulator kinematic control, based on visual servoing is proposed. In the proposed system, a robot image acquired through a CCD camera is processed in order to compute the position and orientation of each link of the robot arm. The robot task is specified as a temporal sequence of reference images of the robot arm. Thus, both the measured pose and the reference pose are specified in the same image space, and its difference is utilized to generate a cartesian space error for kinematic control purposes. The proposed control scheme was applied in a four degree-of-freedom planar redundant robot arm, experimental results are shown / No controle convencional de manipuladores rob?ticos, a trajet?ria desejada ? especificada em espa?o cartesiano e mapeada para espa?o de juntas atrav?s do modelo cinem?tico inverso do manipulador.

The aim of this thesis is to investigate how images can be used to provide emotional feedback on user experience. The report describes the iterative process of developing OakMood, an image-based design evaluation method that provides designers with user generated visual feedback. OakMood enables users to provide emotional feedback on web user experience by choosing images that correspond to their experience of an interaction. The images have been rated by an online crowd according to nine emotions, hence providing emotive characteristics for each image. Results are subsequently presented as mood boards and charts to designers and stakeholders. In addition to providing emotional user feedback on design, OakMood aspires to reflect branding elements of a website. Findings in this study indicate that image-based user feedback can provide valuable insights in the design process. Furthermore, results also indicate that users find images to be an engaging and useful methodology to assess emotional response to user experience. / Syftet med denna studie är att utreda huruvida bilder kan användas för att ge emotionell feedback på användarupplevelse. I rapporten beskrivs den iterativa processen av utvecklingen av OakMood, en bildbaserad design-utvärderings-metod som förser designers med användargenererad visuell feedback. OakMood gör det möjligt för användare att förse emotionell feedback på webbaserad användarupplevelse genom att välja bilder som stämmer överens med deras upplevelse av interaktionen. Bilderna har tidigare blivit bedömda utifrån nio känslor, vilket ger varje enskild bild en unik känslomässig karakteristik. Resultaten presenteras i form av mood boards och diagram till designers och intressenter. Utöver emotionell feedback strävar OakMood efter att ge värdefull feedback på hur användarupplevelse kan spegla varumärke. Resultaten av denna studie indikerar att bildbaserad användarfeedback kan ge användbara insikter i designprocessen. Vidare indikerar resultaten att användare finner att bilder är en engagerande och lämplig metod att känslomässigt utvärdera användarupplevelse.

Lors d’une tâche de pointage manuel, la présence de corrections rapides, adaptées, automatiques et même réflexes (Franklin et Wolpert, 2008) suite à une perturbation par saut de curseur a pu être observée dans de nombreuses études. Ici, nous avons souhaité déterminer si ces corrections étaient purement réflexes où si elles étaient amorcées seulement lorsque la perturbation mettait en péril l’atteinte de la cible ; ces corrections ont-elles aussi un aspect fonctionnel ? Dans une première expérience nous avons fait varier la taille des cibles (5 ou 30 mm de diamètre) et des sauts du curseur (5, 15 ou 25 mm) de manière à obtenir certaines combinaisons où la cible pourrait être atteinte sans qu’aucune correction du mouvement pour contrecarrer l’effet du saut du curseur ne soit nécessaire. Des corrections réduisant l’erreur d’environ 65% ont été observées dans toutes les conditions. Dans une seconde expérience, les participants devaient atteindre une très grande cible (arc de 30°) et un saut de curseur de 15 mm était introduit pour certains essais peu de temps après l’amorce du mouvement. Les participants ont modifié leur mouvement dans le sens opposé à celui de la perturbation, et cela même s’ils n’avaient pas détecté consciemment le saut. Cependant, ces corrections étaient moins rapides et plus petites (42% de l’amplitude du saut de curseur) que celles observées lors de la première expérience. Nos résultats supportent le fait que l’amorce des corrections pour des erreurs de trajectoire induites expérimentalement soit de nature réflexe. Un deuxième processus serait alors responsable du déroulement de ces corrections ; ce deuxième processus est basé, entre autres, sur les caractéristiques de la cible. / Cursor-jump experiments have suggested the existence of quick, efficient, automatic and even reflexive (Franklin and Wolpert, 2008) online correction processes in manual aiming movements. In the present study, we wanted to determine whether corrections for a cursor jump are purely automatic/reflexive or whether they are functional in that they occur only when they are required for the target to be reached. In a first experiment, we used different target sizes (5 mm to 30 mm) and cursor-jump amplitudes (5 mm to 25 mm) so that for some target size/cursor-jump combinations, no correction would be needed to reach the target. In all cases, we observed a correction for the cursor-jump. This correction reduced the error induced by the cursor jump by 60-70%, regardless of target size. In a second experiment, we asked participants to point at a large wedge (30° of circular arc). For some trials, a cursor-jump translated the location of the cursor laterally by 15 mm soon after movement initiation. Participants never consciously detected the cursor-jump but clearly modified the trajectory of their movement in the direction opposite to that of the cursor-jump. These corrections were smaller than those observed in the first experiment (42% of the cursor-jump). Our results indicate that the initiation of a correction for a cursor-jump is more reflexive than it is functional. A second correction process would tailor the movement's initial impulse based on the target characteristics.

In this context, the bilateral training with visual feedback through a mirror has shown promising results, although few studies had used this treatment approach. The aim of this study was to analyze the effects of training with bilateral symmetrical tasks and systematic progression in addition to mirror visual feedback (MVF) on the quality of movement and function of the paretic UL in individuals with chronic hemiparesis. The study included 16 patients post stroke, with UL moderate recovery, which were randomly divided into experimental (EG, n = 8) and control group (CG, n = 8). Both groups performed one hour sessions, 3 times a week, during 4 weeks, involving functional bilateral symmetrical exercises with systematic progression, but the EG performed the tasks observing the movement of the non paretic UL reflected on the mirror, while the CG observed paretic UL directly. The Test d Évaluation des Membres Supérieurs de Personnes Âgées (TEMPA) was used as a primary outcome measure to check the function and quality of movement of the paretic UL. As secondary measures, we used the modified Ashworth Scale, Fugl-Meyer Scale (FMS) and the sense of movement as part of the sensory evaluation of the FMS. The variables analyzed did not show differences between groups, however the TEMPA total score showed main time effect (p = 0.01). When analyzed separately, bilateral tasks also showed a time effect on total score (p = 0.01), functional graduation (p = 0.01) and task analysis (0.01). The FMS also showed a time effect (p = 0.02), without differences between groups. Both groups showed gains after the intervention, without differences between groups. It was observed that the gains were most important in the bilateral tasks of TEMPA, which can influence the quality and function while performing tasks of daily living involve both upper limbs. Probably, these results were due to the similarity of both training and MVF or bilateral training using functional movements could help in the recovery of UL, with no apparent effect over the use of the mirror. / Embora haja algum grau de recuperação motora após o Acidente Vascular Encefálico (AVE), muitos indivíduos permanecem sem uso funcional do membro superior (MS), mesmo na fase crônica. Nesse contexto, surge o treino bilateral com feedback visual através do espelho, que vem mostrando resultados promissores, apesar de poucos estudos utilizando esta abordagem de tratamento. O objetivo deste estudo foi analisar os efeitos do Treino com o Espelho utilizando tarefas bilaterais simétricas e progressão sistematizada sobre a qualidade do movimento e a função do MS parético em indivíduos com hemiparesia crônica. Participaram deste estudo 16 indivíduos com comprometimento moderado do MS, divididos em grupo experimental (GE, n=8) e controle (GC, n=8). Os dois grupos realizaram sessões de 1 hora, 3 vezes por semana, durante 4 semanas, envolvendo exercícios bilaterais simétricos funcionais com progressão sistematizada O GE realizou as tarefas observando o MS não parético refletido no espelho, enquanto o GC observava o MS parético diretamente. Foi utilizado o Teste de avaliação funcional dos membros superiores (TEMPA) para verificar a função e qualidade do movimento do MS parético, Escala modificada de Ashworth, Escala de Fugl-Meyer (EFM) e o sentido de movimento como parte da avaliação sensorial da EFM. As variáveis analisadas não mostraram diferenças entre os grupos, entretanto a pontuação do TEMPA total mostrou efeito principal de tempo (p=0,01). Quando analisadas separadamente as tarefas bilaterais também mostraram efeito de tempo na pontuação total (p=0,01), graduação funcional (p=0,01) e análise das tarefas (0,01). A EFM também apresentou efeito de tempo (p=0,02), sem diferenças entre os grupos. Observou-se que os ganhos foram mais importantes nas tarefas bilaterais do TEMPA, o que pode influenciar a qualidade e a função durante a realização de tarefas do dia-a-dia que envolvam os dois membros superiores. Acredita-se que os resultados encontrados foram devido à similaridade do treino e tanto o efeito produzido pelo espelho quanto o treino bilateral utilizando movimentos funcionais podem auxiliar na recuperação do MS, sem aparente efeito superior do uso do espelho.

Summary: The aim of our study was diagnosis and rehabilitation of vestibular loss in patients with vestibular schwannoma. In the first part we focused on analysis of a group of patients before resection of vestibular schwannoma, mainly on evaluation of gain of posturography and on optimalisation of diagnostic algorithm of vestibular pathology. Throughout the second experiment, we studied if rehabilitation of postural gait with visual biofeedback will speed up vestibular compensation in patients after resection of vestibular schwannoma. The group consisted of 44 patients, who underwent surgical removal of vestibular schwannoma. Before surgery each patient underwent clinical vestibular examination, electronystagmographic recordings and posturography. In the second part of the study 17 patients from previous group were chosen. These patients underwent rehabilitation and rehabilitation with biofeedback. For evaluation was used independent samples T-test and cross-tabulation. A great number of variables were reduced by factor analysis. For statistical analysis of the group with rehabilitation was used nonparametric Wilcoxon signed rank test. Statistical analysis revealed that the most typical parameter for vestibular pathology is the time of the step quick turn test, which is a part of posturography. We proved...

[pt] A presente dissertação parte de um estudo realizado no Instituto Nacional de Educação dos Surdos que pensa as questões das mensagens visuais de jogos de computador destinados à aquisição da fala de crianças surdas. Os jogos, conhecidos como Jogos de Voz e desenvolvidos no Laboratório de Processamento Digital da Fala, da Faculdade de Engenharia Elétrica e de Computação da UNICAMP, na tese de doutorado de Antônio Marcos de Lima Araújo, consistem na retroalimentação visual da fala do jogador. Isto é, enquanto a criança exercita o controle dos órgãos de fonação em um microfone ligado ao computador, ela compreende e assimila o exercício através de uma resposta gráfica e ilustrativa gerada em tempo real na tela do computador. A criança vê o que está falando. Dos quatorze módulos dos Jogos de Voz que foram jogados por crianças com idade entre 6 e 12 anos, em seções regulares, durante um ano, na Divisão de Fonoaudiologia, DIFON, do INES, foram selecionados para análise os dois mais jogados nesse período. A avaliação dos jogos de retroalimentação visual para crianças surdas, que buscam representar visualmente o que ocorre no instante da fala, indica que o design exerce papel determinante na aquisição dos resultados a que se propõem. / [en] This thesis begins with a study at the Instituto Nacional de Educação dos Surdos (Brazilian Institute of Deaf Education) examining the visual messages of computer-based game of speech training for deaf children. The game, known as Jogos de Voz, developed by DS Antonio Marcos de Lima Araújo, as his thesis at the Laboratory of Digital Processing Speech, of the College of Electric Engineering and Computation of UNICAMP, consists of the visual feedback of the player`s speech. That is, while the children exercise their articulatory coordination on the computer microphone, they run through a graphical and illustrative reply in real time on the computer screen. The child sees what he or she is speaking. Of the fourteen modules of the Games of Voice that have been played by children aged 6 to 12 years, in regular sessions, during one year, in the Division of Fonoaudiologia (DIFON) of the INES the two most played modules in this period were selected for analysis. Evaluation of games of visual feedback for deaf children, that they seek to represent visually what occurs at the moment when speech is being produced, indicates that design exerts determinative role in reaching the game`s proposed objectives.
