Testo completoThe notion of the orthos logos (abbr. OL) is vital and decisive for Aristotle’s ethical project. The question of what OL really means is a vigorously debated issue. But what the OL exactly is still remains ambiguous and obscure. The purpose of my dissertation is to inquire into the philosophical contribution of the OL in Aristotle’s Ethics. To fulfil this goal, it is essentially to determine what the OL is and what the OL can do. Through this inquiry I seek to present a comprehensive and consistent reading of important parts of Aristotle’s Nicomachean Ethics. I will argue that the OL is the practical syllogism per se, which could tell moral people what should they do and why should they do this or that. But it could also appear to be something else for moral learners, since they are not capable of fully understanding the syllogism yet.

Testo completoTherapies assisted by powered Wearable Robotic Devices for treating lower limb impairments – ROBOT-AIDED gait training – have been increasingly used in addition to conventional therapeutic approaches, in the fields of rehabilitation and assistance. Particularly, powered exoskeletons and orthoses have been highlighted. These complex robotic systems require the design of bioinspired control architectures, that emphasizes modularity, determinism, portability and effective actuation. The main goal proposed in this work comprises the development of a powered knee orthosis (PKO) system, embedded with wearable gait sensors, capable of providing assistance to motion while monitoring the human gait, in terms of kinematic, kinetic and physiologic parameters. Furthermore, the overall validation of the rehabilitative tools is carried out with the development of motion control strategies for knee motion assistance, suitable for distinct types of therapies and pathologic patients. These strategies are integrated in a bioinspired hierarchical control architecture, that allows the distribution of controllers (low-, mid-, and high-level) according to the human motor functioning principles. Moreover, an adaptive real-time gait segmentation method capable of detecting six human gait events is also presented and validated, and further integrated in the PKO system. This first set-up of the system was validated with healthy subjects, on treadmill gait training, in order to prove the well-functioning of the designed components, the effectiveness of the actuation and impact of the orthosis in the users. Overall, the outcomes are promising, with a successful validation of the motion assistance strategies as well as the adaptive gait segmentation tool. Furthermore, this work also presents the conceptual design and technical description of a new bioinspired, real-time, modular, and effective architecture for smart wearable orthoses system, entitled SmartOs, capable of integrating an active ankle-foot orthosis (PAFO) and the PKO, with wearable gait sensory systems and advanced gait methods.
Terapias assistidas por sistemas robóticos ativos e vestíveis para tratamento de deficiências dos membros inferiores têm vindo a ser cada vez mais utilizadas em adição a terapias convencionais, em reabilitação e assistência. Em particular, exosqueletos e ortóteses ativas tem sido destacada. Estes sistemas complexos requerem o projeto de arquiteturas de controlo, que realçam modularidade, determinismo, portabilidade e uma atuação eficaz. O objetivo principal proposto neste trabalho inclui o desenvolvimento de um sistema para uma ortótese ativa do joelho (PKO), embebido com sensores da marcha, capaz de assistir o movimento enquanto monitoriza a marcha humana, em termos de cinemática, cinética e parâmetros fisiológicos. A validação completa desta ferramenta reabilitativa decorreu com a criação de estratégias de controlo para assistir o movimento do joelho, adequadas para diferentes terapias e pacientes patológicos. Estas estratégias foram então integradas numa arquitetura de controlo bioinspiradas, que permite a definição de controladores (baixo, médio, e alto nível) relacionadas com os princípios do funcionamento do motor humano. Além disso, um algoritmo adaptativo de segmentação em tempo-real da marcha, capaz de destacar seis eventos, é também apresentado e validado, com posterior integração no sistema PKO. Esta primeira configuração do sistema foi validada com sujeitos saudáveis, em treadmill, de forma a provar o correto funcionamento dos componentes desenhados, a eficácia da atuação, e o impacto da ortótese nos utilizadores. No geral, os resultados foram promissores, com uma validação bem-sucedida das estratégias de assistência ao movimento e também da ferramenta segmentação da marcha. Além disso, este trabalho também apresenta o desenho conceptual e descrição técnica de uma nova arquitetura em real-time, bioinspirada, modular e eficaz para sistemas ortópticos inteligentes, intitulada SmartOS, capaz de integrar uma ortótese ativo do tornozelo (PAKO) e o PKO, com sensores da marcha vestíveis e algoritmos da marcha avançados.

Testo completoIntroduction: Obstructive sleep apnea syndrome (OSAS) is a common public health issue. Management with continuous positive airway pressure (CPAP) is the gold standard, but many people are unable to cope with it or refuse it. So, titratable mandibular advancement devices (MADs) are gaining in popularity, because they provide real long-term solutions. The myofunctional approach, which involves lingual exercises, is an additional measure that could improve OSAS management. To this end, we have observed the association of these two elements by creating an active MAD (AMAD). Indeed, actively repositioning the mandible in the advanced position may well mitigate some of the adverse effects of conventional MADs. Objectives: To compare the efficacy of AMADs in a routine care environment with conventional titratable MADs in adult patients with severe OSAS who do not want or do not tolerate CPAP therapy. The evaluation will focus on the overall response rate, which includes changes in apnea-hypopnea index (AHI) and compliance. Methodology: 18 participants completed the entire study, 8 in the MAD group and 10 in the AMAD group. After completing a series of questionnaires, they were asked to undergo a dental and temporomandibular joint (TMJ) examination, and their first polysomnography (PSG). They all received the treatment. After the patients had used it for at least 3 months, another series of questionnaires was completed, and another clinical examination and a second PSG were carried out. Results: AHI (p <0.001), time spent with SpO2>90 (p = 0.002), desaturation index (p = 0.004) and number of micro-arousals (p = 0.007) significantly decreased in both groups, with no significant difference between groups. The overall results of the questionnaires showed a significant improvement between the beginning and the end of the study for both groups with no significant difference between the groups for drowsiness, fatigue, normal activities and sleep quality variables. However, a much higher salivation rate was reported with the AMAD, as well as longer wake times during sleep periods and a tendency for the device to be worn for less time during the night. It was also observed that sleep quality does not normalize as much as with conventional MADs. Subjectively, patients in the AMAD group reported fewer TMJ clicks (p = 0.05) and fewer occlusion changes (p = 0.05) in the short term, compared to the MAD group. Finally, there were no significant differences between the groups in the overall response rate (p = 0.64). Conclusion: AMAD is an equipotent treatment option, based on sleep indexes, when compared to conventional titratable MADs. While AMADs produce subjectively less TMJ clicking and occlusal changes in the short term, it is essential to conduct a large-scale study to confirm whether the tendencies to not sleep as well and to use AMADs for shorter periods than MADs can be explained.

Testo completoO acidente vascular cerebral (AVC) é a terceira principal causa de incapacidade motora adulta. A reabilitação da marcha com um treino repetitivo e orientado ao doente, possível com ortóteses ativas (OAs), potencia a recuperação da mobilidade. Contudo, é necessário ajustar a reabilitação da marcha às atuais necessidades do sujeito, bem como integrar sensores vestíveis nas OAs para avaliar objetivamente a marcha. Esta tese visa o desenvolvimento do SmartOs, um sistema ortótico ativo, modular, e vestível, com o intuito de providenciar um treino de marcha repetitivo e orientado às necessidades de doentes com AVC, e de avaliar a locomoção do doente por meio de dados cinemáticos e musculares. Esta tese inclui cinco fases de investigação. Primeiro, foi desenvolvida uma estrutura modular para integrar, de forma inovadora e eficaz, sistemas sensoriais, ferramentas de análise da marcha, e estratégias de controlo nas OAs. Segundo, foi desenvolvido um laboratório portátil de análise de marcha com quatro sistemas sensoriais, passíveis de serem utilizados em stand-alone ou combinados com sistemas externos. O benchmarking com sistemas comerciais demonstrou a potencialidade destes sistemas sensoriais para a avaliação objetiva da locomoção. Terceiro, foi desenvolvida uma máquina de estados com limites adaptativos para a deteção de eventos da marcha, a qual demonstrou ser adequada como benchmarking para avaliação de eventos humanos da marcha. Quarto, foi criada uma ferramenta de machine learning para o reconhecimento e previsão de modos de locomoção e transições. Esta ferramenta destaca-se pela classificação precisa de direções e terrenos com uso exclusivo de dados cinemáticos. Por último, foi desenvolvida uma arquitetura de controlo hierárquica com quatro estratégias de controlo. As estratégias de trajetória orientada ao sujeito e impedância adaptativa fornecem um treino de marcha repetitivo e assist- as-needed, respetivamente. As estratégias baseadas na eletromiografia e na interação homem- OA contribuem para o fortalecimento muscular. Em suma, os resultados indicam que o SmartOs está funcional para futura aplicação em ambiente clínico quer como uma solução de assistência personalizada, quer como uma ferramenta de avaliação da marcha de doentes com AVC.
Stroke is the third leading cause of adult long-term motor disability. Gait rehabilitation approaching user-oriented and repetitive gait training has the potential for long-term mobility recovery. Active orthoses (AO) can tackle these rehabilitation abilities. More research is needed to foster gait rehabilitation oriented to the current user’s needs and to integrate wearable sensors into AOs for objective gait assessment. This thesis aims the development of SmartOs, a smart, modular, wearable active lower limb orthotic system, to foster user-oriented and repetitive gait training in impaired gait due to stroke and to evaluate human motor condition using kinematic and muscular gait measures. This work includes five research stages. First, a modular framework was implemented to integrate into an innovative and effective manner, wearable sensor systems, gait analysis tools, and control strategies into AOs. Second, a wearable motion lab including four wearable sensor systems, with an open-architecture for both stand-alone or third-party systems use, was successfully developed. The benchmarking analysis with commercial systems outlined that the sensor systems are purposeful for objective evaluation of the user’s motor condition. Third, a gait event detection tool through a finite state machine with an adaptive threshold-based structure was developed for detecting gait events in daily locomotion. Results show that the tool is suitable as a benchmark for detecting human gait events. Fourth, a machine learning-based recognition and prediction tool was achieved to classify locomotion modes and transitions. This tool advances the state-of-the-art by demonstrating that the exclusive use of kinematic data successfully classifies different walking directions and terrains. The last research stage made the SmartOs a multi-functional system through a hierarchical control architecture with four assistive control strategies. The user-oriented trajectory and adaptive impedance controls foster repetitive and assist-as-needed gait training, respectively. Both the EMG-based and user-orthosis interaction based control contribute to muscle strengthening. Findings indicate that SmartOs is functionally operative for a future clinical application as a personalized assistive and gait assessment solution of stroke survivors.
