Título anterior: Proposta de avaliação com tabuleiro portátil de atividades de vida diária / Orientador: Cynthia Yukiko Hiraga / Banca: José Angelo Barela / Banca: Maria Georgina Marques Tonello / Resumo: A função do membro superior inclui a capacidade de alcance direcionado, preensão e manipulação de objetos. Tais capacidades formam a base motora requerida para a realização das atividades de vida diária (AVD) com eficiência. A eficiência do uso das mãos nas AVD pode ser afetada por patologias, bem como pelo envelhecimento. O desempenho motor de forma geral apresenta um declínio em idosos, aproximadamente à partir dos 60 anos. O presente estudo focaliza o uso do tabuleiro portátil de atividade de vida diária (TPAVD) para avaliação do desempenho em tarefas manuais. O TPAVD consiste de atividades envolvendo o uso de uma ou ambas as mãos em tarefas simples que os seres humanos realizam no seu cotidiano. O objetivo do presente estudo é avaliar a coordenação motora fina usando o tabuleiro portátil de AVD's (TPAVD) ao longo do envelhecimento. O estudo contou com aproximadamente 60 participantes (15 participantes em cada grupo por faixa etária) dentro das seguintes faixas de idade, a saber: 20 a 25 anos, 45 a 50 anos, 60 a 65 anos, 70 anos ou mais, sem qualquer diagnóstico de patologia musculoesquelética e lesão neurológica que apresente problema e/ou disfunção no membro superior. As tarefas do TPAVD foram divididas em quatro subtestes distintos. Dessa forma, o tempo de execução de cada subteste e a soma do tempo de cada subteste foram utilizados como variável dependente. A hipótese do estudo foi de que o TPAVD poderia captar diferenças no tempo de execução entre os diferentes grupos ...

These capabilities form the motor base required to perform the activities of daily living (ADLs) efficiently. The efficiency of the use of hands in the ADLs can be affected by diseases and aging process. The general motor performance shows a decline in the elderly, at about the age of 60. This study focuses on the use of portable board activity of daily living (PBADL) for performance evaluation on manual tasks. The PBADL consists of activities involving the use of one or both hands on simple tasks that humans perform in their daily lives. The aim of this study is to examine fine motor skills using portable board of ADLs (i.e., PBADL) across a range of ages. The study included approximately 60 participants (15 participants in each group by age group) within the following age groups, 20 to 25 years, 45-50 years 60-65 years 70 years or more, without any musculoskeletal diagnosis and neurological injury pathology or presenting problem and/ or dysfunction in the upper limbs. The PBADL tasks were divided into four distinct subtests. Thus, the execution time of each subtest and the total time of each subtest were used as dependent variables. The study hypothesis was that the PBADL could capture differences in execution time between different groups according to age group. That is, the older the participant the greater the time to execute the tasks in the PBADL. The results of this study confirmed the differences in performance of TPAVD tasks between age groups, considering the sum of the times of the subtests. In relation to the time of each subtest, subtest 2 was not presented the expected differences. The times subtests 1, 3 and 4 have been gradually increasing with age. The TPAVD is a potential methodology to be used as tool for evaluation of hand function / Mestre

Previous research has demonstrated a retrieval-induced forgetting effect for verbal material (Anderson & Spellman, 1995), colours and shapes (Ciranni & Shimamura,1999), eyewitness testimony (MacLeod, 2002), and images of novel actions (Koutstaal et al., 1999). However, little research has been conducted into retrieval-induced forgetting and self-performed actions. A recent study by Sharman (2011) demonstrated retrieval-induced forgetting for familiar and bizarre self-performed actions. The current thesis aims to examine retrieval-induced forgetting and actions including self-performed and observed actions, and combinations of self-performed and observed actions. The first experiment demonstrated retrieval-induced forgetting for novel motor sequences. In addition, retrieval-induced forgetting was also found for less novel actions (Experiments 3 and 4) for both typical and non-typical self-performed actions (Experiment 3) and memorable self-performed actions (Experiment 4). Experiment 2 demonstrated a retrieval-induced forgetting effect for objects associated with actions suggesting that retrieval-induced forgetting effects occur both for the action and the object. However the findings of experiment 5 suggest that retrieval-induced forgetting may not occur for goal-orientated actions. These experiments may suggest that retrieval-induced forgetting occurs for non goal-orientated actions, but may not occur for goal-orientated actions. These findings are discussed in terms of the inhibitory account.

Two studies were conducted to investigate the effect of mental imagery training on the magnitude and strength of individuals' self-efficacy for a dart throwing task, and to compare the utility of single-subject and group design studies in investigating imagery in the motor skill domain. The first study employed a multiple-baseline-across-subjects design, in which six (n=6) subjects were administered a 15-session mental imagery training program following baseline sessions of varying lengths. The first ten imagery training sessions included a three minute relaxation component, followed by four minutes of specific imagery training (incorporating self-perception imagery and imagery vividness and controllability training). Subjects were then asked to stand, perform a one minute centering exercise, and to image successful performance of the task. This was immediately followed by the completion of a self-efficacy and imagery rating scale, and actual performance of the task while blindfolded. Two subjects showed that their self-efficacy magnitude for the task had increased as a result of the intervention, one subject demonstrated an increase in self-efficacy strength due to imagery training, and all subjects evidenced a change in their overall pattern of performance from the baseline to intervention phases. The second study used a more traditional group design in which nineteen (n=19) randomly assigned subjects were administered a similar 15-session mental imagery training program. These subjects were compared to a control group of nineteen (n=19) subjects on their ratings of self-efficacy magnitude and strength prior to, immediately following, and eight days after the completion of the imagery intervention. For this study, the intervention differed from the multiple-baseline study, in that the subjects were not required to complete the self-efficacy or imagery rating scales on each day of the intervention, and were not required to physically perform the task. Two 2 x 3 Analyses of variance showed no significant differences between the control and experimental groups on ratings of self-efficacy magnitude or strength. It was concluded from the multiple-baseline study that imagery was able to enhance self-efficacy for the dart throwing task in subjects who were high ability imagers, had previous experience at throwing darts, believed in the performance-enhancing capabilities of mental imagery training, and had been exposed to relaxation and imagery procedures prior to the study. It was concluded from the group design study however, that imagery had no effect on self-efficacy for the dart throwing task for subjects who had previous experience at imagery training, and who believed in the potential for imagery to enhance performance. A comparison of the two designs demonstrated the effectiveness of the single-subject design study in more fully investigating imagery's effect on various aspects of motor skill performance. In particular, the importance of high imagery ability, the use of more task specific measures of imagery ability, and the possibility that performance-based sources of efficacy information may be the only avenue for enhancing self-efficacy for certain individuals, were issues that were raised as a result of the single-subject design study. It was further concluded that the systematic use of such designs provided a practical, relevant and comprehensive evaluation of the effect of imagery on aspects of motor skill performance, although the complementary use of both types of research was recommended. / Graduate

Orientador: Eduardo Kokubun / Resumo: Affective responses during exercise are related to exercise adherence and current/future exercise behavior. However, there is large inter-individual variability in affective responses to exercise. Such variability is partly explained by individual differences in preference for and tolerance of the intensity of exercise. Thus, the aims of this PhD thesis were: Article 1 - to adapt the Preference for and Tolerance of the Intensity of Exercise Questionnaire (PRETIE-Q) for the Brazilian population and to perform an initial psychometric evaluation; Article 2 - to test the structural validity of the PRETIE-Q in a diverse population sample and to evaluate its factorial invariance across gender and age subgroups; Article 3 - to explore the factors associated with Preference for and Tolerance of the exercise intensity in a diverse population sample, as well as to provide population-based normative values; Article 4 - to test whether the constructs of preference for and tolerance of exercise intensity are associated to exercise behavior longitudinally in a diverse population sample. For this, the following methods were used: Article 1 - translation and back-translation, production of a Brazilian Portuguese version of the PRETIE-Q, and psychometric evaluation and construct validation using cross-sectional correlations between the Preference and Tolerance scores and physical activity variables; Article 2 - confirmatory factor analysis and a test of multigroup factor invar...
