Abstract (sommario):

Introdução: O estado atual de avanço tecnológico e da Medicina no cuidado perinatal proporciona um cenário favorável em caso de necessidade de tratamento de neonatos graves. Objetivo: Comparar a evolução clínica recém-nascido (RN) a termo com asfixia perinatal (AP) moderada e grave submetidos a um protocolo de avaliação neurológica neonatal seriada durante período de internamento hospitalar, com a evolução clínica daqueles não submetidos ao protocolo de avaliação. Método: Estudo epidemiológico com 112 RN a termo, admitidos na unidade de terapia intensiva neonatal (UTIN) da Maternidade Nossa Senhora de Lourdes, em Aracaju, Sergipe. Os RN foram acompanhados durante o período intra-hospitalar e em ambulatório de seguimento. Iinvestigouse a evolução clínica da criança, o tempo de permanência hospitalar e presença de atraso no desenvolvimento das habilidades neuromotoras. Resultados: O grupo intervenção mostrou uma média de tempo de internamento hospitalar menor em dias (9,8 ± 1,6) (p<0,001) que o grupo controle (28,8 ± 4,1) e uma prevalência de atraso em desenvolvimento neuromotor significativamente menor (15,4 ± 1,7) (p=0,05) que o grupo controle (37,4 ± 7,4). Conclusão: RN submetidos ao protocolo de avaliação neurológica seriada evoluíram para alta hospitalar mais precocemente do que os não submetidos. O atraso no desenvolvimento neuromotor foi maior no grupo controle, não sendo percebida essa evolução desfavorável no grupo intervenção.

Abstract (sommario):

O canabidiol (CBD) tem sido utilizado para tratar inúmeras condições patológicas principalmente doenças que afetam o sistema nervoso central como epilepsia, esquizofrenia e doenças neurodegenerativas crônicas como Alzheimer e Parkinson. A liberação das formulações com CBD, no Brasil, limita em 0,2% a presença de D9-tetrahidrocanabinol, a substância psicoativa da Cannabis sativa. O neurotransmissor dopamina está relacionado com o sistema de recompensa cerebral e com a doença de Parkinson, entre outras funções. O objetivo deste estudo foi administrar cronicamente CBD, em ratos, via gavage, para avaliar o impacto sobre os níveis de dopamina e no desempenho neuromotor. O estudo foi aprovado pela Comissão de Ética em Uso de Animais institucional (protocolo 173/2020). Ratos Wistar, machos (n=8), receberam via gavage 50 μL completado até 1 mL água/dia de CBD (200 mg/mL). Grupo controle recebeu pela mesma via, 1 mL de água/dia (n=8). Os animais foram pesados mensalmente. Findo o período de 90 dias, os animais foram eutanasiados em câmara de CO2 para a coleta de tecido cerebral e isolamento da preparação neuromuscular. A dosagem neuroquímica foi realizada via HPLC/MS-MS após realização de curva de calibração com 1 mg/mL de dopamina e seus metabólitos 3,4-di-hidroxifenilacetico (DOPAC) e ácido homovanílico (HVA), utilizando como padrão interno, 3,4-di-hidroxibenzilamina. O desempenho neuromotor foi avaliado por técnica miográfica convencional e análise histológica dos músculos por procedimentos de rotina. Os resultados foram expressos em média ± EPM ou ± DP, analisados por Anova One way seguido de Tukey, com p<0,05 indicando significância. Não houve diferença significativa na concentração de dopamina e seus metabólitos entre os grupos experimental e controle, CBD não afetou o desempenho neuromotor e as células musculares esqueléticas. Conclui-se que o CBD administrado cronicamente na concentração eleita mostrou-se seguro, sem causar alterações em nível neuroquímico, nem no desempenho neuromotor, além de preservar a célula muscular esquelética.

Abstract (sommario):

A inatividade física e o sedentarismo são comportamentos comuns à maior parte das doenças reumáticas, levando a uma piora do controle destas doenças e a uma menor qualidade de vida. Por outro lado, estudos recentes têm demonstrado que a adoção de um estilo de vida ativo pode auxiliar no tratamento das doenças reumáticas, seja promovendo um melhor controle dos sinais e sintomas ou atenuando diversas comorbidades. O objetivo da presente revisão foi apontar aspectos importantes para a prescrição de atividade física (AF) nas doenças reumáticas. Em geral, um programa de AF voltado à saúde de pacientes com doenças reumáticas deve envolver uma equipe multidisciplinar, que será responsável por realizar as avaliações, o planejamento, a entrega e supervisão do programa. Adicionalmente, o paciente deve ser considerado parte fundamental no sucesso da intervenção, visto que ele precisa aderir de maneira ativa à AF, sendo corresponsável pela execução do programa. Um programa de AF para esta população deve objetivar a melhora da aptidão cardiorrespiratória, força muscular, flexibilidade e desempenho neuromotor. Essas capacidades físicas devem ser desenvolvidas por um programa de treinamento físico que componha o treinamento aeróbio, de força, de flexibilidade e neuromotor. Mais recentemente, novas modalidades/abordagens têm sido incorporadas no tratamento de pacientes com doenças reumáticas, tais como o treinamento intervalado de alta intensidade, o treinamento de força com oclusão vascular e a redução do tempo sedentário. É importante que os profissionais de saúde incorporem estas informações no manejo de pacientes com doenças reumáticas. Unitermos: Exercício físico. Reumatologia. Doenças articulares. Comportamento sedentário. Intervenções comportamentais.

Abstract (sommario):

Este estudo apresenta uma revisão teórica sobre o papel da atenção na realização de tarefas motoras, adotando-se a perspectiva do paradigma sistêmico aplicado ao comportamento motor e sua relação com a abordagem do controle motor na fisioterapia neurofuncional. Foram consultados os bancos de dados Medline, PubMed, LILACS, SciELO, e PEDro, incluindo artigos de 1990 a 2009. Nos estudos pesquisados, observou-se o entendimento da atenção como um agente mediador entre o indivíduo e o ambiente no processo de auto-organização dos subsistemas orgânicos durante a realização de uma tarefa motora. Foram identificadas similaridades entre esta perspectiva teórica sobre a atenção e os pressupostos que fundamentam a abordagem do controle motor na fisioterapia neurofuncional, evidenciando caminhos de investigação científica no sentido de ser mais bem compreendido o papel da atenção na adaptação do sistema neuromotor de pessoas com lesão neurológica e sua efetividade na promoção do movimento funcional humano.

Abstract (sommario):

Robot-aids or Rehabilitators are our chosen neologism to name a new class of robotic devices that represent a substantially departure from prior applications of robotics in rehabilitation. Rather than use robotics as an assistive technology for a disabled individual, we envision robots and computers as supporting and enhancing the productivity of clinicians in their efforts to facilitate a disabled individual's recovery. In this paper, we attempt a brief overview of our work in what promises to be a ground breaking field. We discuss the concept of robot-aided neuro-rehabilitation as a means to deliver therapy, measure patient performance, and also as a design tool. To illustrate the broad spectrum of neurological diseases that this technology might impact, we will illustrate each case with a different pathology, namely cerebral vascular accident (CVA – also known as stroke), Parkinson's disease (PD), and cerebral palsy (CP).

Abstract (sommario):

Noventa e quatro recém-nascidos com encefalopatia hipóxico-isquêmica (EHI), atendidos no Hospital das Clínicas de Ribeirão Preto desde 1982, foram avaliados evolutivamente na fase aguda e por período médio de 47 meses. De 43 casos com EHI 1,40 se recuperaram em 96 horas e 3 faleceram. Dos 40 com EHI II, 37,5% se recuperaram até o sétimo dia e demais permaneceram com alterações. Os 11 casos com grau III faleceram até o segundo mês de vida. As crianças com EHI grau I não apresentaram seqüelas motoras. Do grupo com EHI grau II 34,5% apresentaram paralisia cerebral e 17,7% atraso neuromotor. 80% dos casos com sequela apresentaram exame neurológico anormal além do sétimo dia, na fase aguda da EHI. Epilepsia ocorreu em 17,5% dos casos com EHI grau II e somente no grupo com seqüelas motoras. Teste de QI não evidenciou diferença significativa entre os grupos com grau I, II sem seqüelas motoras e o grupo controle. Com esses dados os autores reafirmaram a importância prognostica da evolução da EHI na fase aguda.

Abstract (sommario):

Objetivo: analisar o efeito da crioterapia moderada com imersão (15º celsius - C), nas respostas inflamatórias musculares, nas variáveis bioquímicas e neuromotoras após uma sessão de exercício de força excêntrico. Procedimentos Metodológicos: 18 homens (18-25 anos) saudáveis, não praticantes de exercício físico e que participaram voluntariamente da pesquisa foram recrutados. Inicialmente foram randomizados em três grupos: Grupo Controle (GC), Grupo Exercício (GE) e Grupo Exercício + Crioterapia (EX + CT). Após a aleatorização, os voluntários seguiram para realização de testes: a) bioquímico (Creatina Quinase - CK), b) neuromotor (amplitude de movimento - ÂNGULO), c) escala de dor - DOR e d) um teste de força isométrica máxima. Em seguida, os grupos experimentais realizaram séries de ações excêntricas máximas para região anterior e posterior da perna no exercício sentadinha. Após a sessão analisou-se CK, ÂNGULO e DOR, nos momentos 24, 48, 72, 96 e 120 horas. Os sujeitos do EX + CT receberam tratamento crioterápico imediatamente após a sessão e nos momentos 12, 24, 36 e 48 horas subsequentes. Resultados: Em comparação com o repouso, os valores de CK, DOR e ÂNGULO apresentaram aumento significativo após as sessões nos grupos experimentais. O GE exibiu valores significativamente superior ao EX + CT em todas as variáveis analisadas. Conclusão: A crioterapia mostrou-se uma alternativa viável no tratamento da miopatia do exercício e da dor muscular tardia.

Abstract (sommario):

The rehabilitation of patients should not only be limited to the first phases during intense hospital care but also support and therapy should be guaranteed in later stages, especially during daily life activities if the patient’s state requires this. However, aid should only be given to the patient if needed and as much as it is required. To allow this, automatic self-initiated movement support and patient-cooperative control strategies have to be developed and integrated into assistive systems. In this work, we first give an overview of different kinds of neuromuscular diseases, review different forms of therapy, and explain possible fields of rehabilitation and benefits of robotic aided rehabilitation. Next, the mechanical design and control scheme of an upper limb orthosis for rehabilitation are presented. Two control models for the orthosis are explained which compute the triggering function and the level of assistance provided by the device. As input to the model fused sensor data from the orthosis and physiology data in terms of electromyography (EMG) signals are used.

Abstract (sommario):

L'objectif de cette thèse était double : i) objectiver les effets de la réathlétisation sur le contrôle neuromoteur de footballeurs de haut-niveau; ii) développer un modèle théorique prédictif de la survenue de blessure chez l'athlète sain. Le modèle expérimental du countermovement-jump (CMJ) a été utilisé pour tester les hypothèses spécifiques à chacune des 5 études réalisées. Les paramètres cinétiques, cinématiques et électromyographiques (EMG) du CMJ étaient calculés au moyen de plateforme de force, caméra rapide et électrodes de surface, respectivement. Trois pathologies des membres inférieurs ont été considérées: rupture du ligament croisé antérieur du genou, chondropathie de genou et lésions musculaires de la cuisse. Dans une 1ère étude, les résultats ont montré que les paramètres biomécaniques et EMG du CMJ de la jambe blessée et de la jambe non blessée étaient altérés dans tous les groupes pathologiques. Le programme SSR (specific sport rehabilitation) de trois semaines a permis d'améliorer significativement ces paramètres caractéristiques du contrôle neuromoteur. Dans une 2ème étude, le niveau de récupération fonctionnelle des footballeurs a été évalué par le biais de deux méthodes: la méthode LSI (limb symmetry index) et la méthode Norm-Values. Les résultats ont montré que la méthode Norm-Values était la plus discriminante. Dans une 3ème étude, la comparaison inter-groupes des paramètres biomécaniques et EMG a permis de mettre en évidence une « signature neuromotrice » spécifique à chaque pathologie. Dans une 4ème étude, les résultats ont montré que la superposition d'une tâche de prise d'information visuelle (tâche secondaire) avait un effet bénéfique sur les paramètres du CMJ (tâche primaire), probablement dû à une « défocalisation » de l'attention des athlètes blessés vers la tâche secondaire. Enfin, dans une dernière étude, le suivi longitudinal de joueurs sains au cours d'une saison a été réalisé avec pour objectif de développer un modèle théorique prédictif de blessure. Ce modèle, basé sur une méthode de machine learning a permis de mettre en évidence des tendances (non significatives) à la survenue de blessures en fonction des caractéristiques neuromotrices des joueurs. Globalement, l'ensemble de ces résultats contribue à l'amélioration des connaissances et des pratiques dans le domaine de la réathlétisation
This thesis had two principal objectives: i), to provide an objective analysis of the impact of sport-specific-rehab (SSR) on the neuromotor control of high-level soccer players ; ii) to develop a theoretical model that could predict the likelihood of injury in healthy athletes. The experimental countermovement jump (CMJ) model was employed to test the specific hypotheses associated with each of the five studies. The kinetic, kinematic and electromyographic (EMG) parameters of the CMJ were calculate using a force platform, a high-speed camera and surface electrodes, respectively. Three pathologies of the lower-limb were considered: anterior cruciate ligament rupture of the knee, knee chondropathy and muscular lesions of the thigh. The initial study demonstrated that the biomechanical and electromyographic parameters of the CMJ of the injured leg and the non-injured leg were altered in all pathological groups. The three-week SSR programme led to a notable improvement in these parameters, which are indicative of neuromotor control. In a second study, the level of functional recovery of the soccer players was evaluated using two methods: the LSI (limb symmetry index) and the Norm-Values method. The findings indicated that the Norm-Values method was the most effective in discriminating between the groups. In a third study, an intergroup comparison of biomechanical and EMG parameters revealed the existence of a 'neuromotor signature' specific to each pathology. In a fourth study, the results demonstrated that superimposing a visual information-gathering task (secondary task) had a beneficial effect on CMJ parameters (primary task). This was likely due to the injured athletes' attention being defocused towards the secondary task. In a final study, healthy players were monitored over the course of a season with the objective of developing a theoretical predictive model of injury. This model, based on a machine learning method, revealed non-significant trends in the occurrence of injuries as a function of the neuromotor characteristics of the players. Overall, these results contribute to advancing knowledge and practices in the field of rehabilitation

Abstract (sommario):

Chez les aînés âgés de 75 ans et plus, 36% des chutes sont associées à un problème d'équilibre. Devant ces faits, face l'augmentation progressive de la population âgée (20% en l'an 2031), de même que devant la grande consommation de services sociaux et de santé (près de 50% des coûts), un entraînement neuromoteur multisensoniel pouvant intervenir positivement dans la prévention des chutes revêt une importance capitale. Le programme d'entraînement neuromoteur multisensonel faisant l'objet de la présente étude est basé sur les données scientifiques récentes sur l'organisation du système nerveux et du contrôle neuromoteur selon la perspective des systèmes dynamiques. Par une approche systémique, le programme vise à rehausser la capacité du SNC à adapter les entrées sensorielles et cibler rapidement l'information pertinente pour générer la synergie musculaire appropriée à la tâche et à l'environnement. Les seances, variées et actives, font appel à la motricité globale. Elles comprennent des situations sollicitant des prédominances sensorielles différentes et des conditions de conflits intersensoriels nécessitant des ajustements posturaux.

Abstract (sommario):

O músculo reto do abdome é um importante músculo da parede abdominal, responsável pela estabilização e função da coluna, tanto em atividades atléticas quanto em atividades cotidianas. Entretanto, pouco se conhece sobre o controle neuromotor de tal estrutura em atividades voluntárias, como os exercícios abdominais, e como as diferentes tarefas agem na ativação segmentada das porções musculares do músculo reto do abdome. Em geral, a presente dissertação teve como objetivo investigar o controle neuromotor do músculo reto do abdome em diferentes tarefas voluntárias através de quatro experimentos. O primeiro experimento teve como objetivo descrever as características morfológicas do músculo reto do abdome, em particular sua área de secção transversa, ao longo do comprimento longitudinal do músculo, utilizando as imagens do projeto homem visível (NLM). O segundo experimento objetivou o mapeamento dos pontos motores para cada porção muscular. O terceiro experimento investigou o controle neuromotor das diversas porções musculares em tarefas isométricas de baixa intensidade. E por fim, o quarto experimento investigou o comportamento das porções musculares em diferentes tarefas isométricas em condição de fadiga neuromuscular. Baseado nos experimentos apresentados neste estudo pode-se concluir que o músculo reto do abdome é uma estrutura extremamente complexa em sua arquitetura, sendo caracterizada por diversas porções musculares que se interconectam através de aponeuroses tendíneas, onde, possivelmente nenhuma fibra muscular atravesse seus ventres. Devido a tal consideração, supõe-se que o controle das diversas porções, por sua independência anatômica, dependa de um aporte nervoso diferenciado para o controle motor. Assim, podem-se definir pelo menos um nervo para cada porção em ambos os ventres. Devido a tais considerações, se torna plausível considerar um controle neuromotor diferenciado de cada porção muscular, mas os experimentos relacionados à ativação muscular de baixa intensidade mostram um controle central compartilhado por todos os ventres e um ganho associado à tarefa para cada porção de forma distinta. Os resultados do experimento de indução de fadiga demonstraram diferenças no espectro, mostrando diferenças no controle neuromuscular em função das tarefas, mas não apresentou diferenças na análise temporal. Conclui-se, então, que existe uma ativação seletiva para cada porção muscular, embora não se consiga ativar apenas uma região do ventre muscular, em função do controle central associado. Deste modo, parece que a alteração da tarefa possui valor na alteração da ênfase para cada porção muscular, mas questiona-se o valor deste ganho para objetivos relacionados à força ou hipertrofia muscular.
The rectus abdominis is an important muscle of the abdominal wall; it is responsible for the stabilization and function of the spine, as to athletic activity as daily activity. However, we do not have enough knowledge about the neuromotor control of this structure in voluntary activities, like abdominal exercises and how different tasks alter the segmental activation of the different parts of the abdomen. The aims of the present dissertation were to investigate the neuromotor control of the rectus abdominis in different voluntary tasks by four experiments. The aim of the first experiment was to describe morphologic characteristics of the rectus abdominis, in particular its transverse cross section, using the visible human project (NLM). The aim of the second experiment was to define motor points to each portion of the rectus abdominis. The aim of the third experiment was to investigate the neuromotor control of the each portion of the rectus abdominis in isometric low intensity tasks. And, the fourth experiment investigated the behavior of the different portions of the rectus abdominis in different isometric tasks on neuromuscular fatigue. The present experiments showed that the rectus abdominis muscle has an extremely complex structure in its architecture, defined by different portions without connection one each other and it is defined by a lot of portions that connect by tendinius aponeuroses. It could be considered that the control of the different portions, by your anatomic characteristics, have different nerves to each portion that facilitates the motor control. We found at least one nerve to each portion. But it is possible that exist different neuromotor control to each portion, so the next experiments related to low intensity of the muscular activation showed a central control shared by all portions and the gain associated to each task. The result of the fatigue experiment showed differences on spectral analysis and changes in neuromuscular control by the tasks, but did not present differences on temporal analysis. In conclusion, there is selective activation to each muscular portion; however, it could not be activated only one portion of the rectus abdominis to a specific task. Therefore, it can be that the alteration of the task has an important value on each muscular portion, but it does not know if this gain has any value to strength and hypertrophy.

Abstract (sommario):

A comprehensive system for investigation of biomechanical and neuromuscular processes involved with producing handwriting and drawing was developed. The system included a pen-like grip measuring device that enabled the variations of finger grip force associated with writing and drawing to be measured while holding the pen in tripod grip. The pen was integrated with a digitiser tablet for recording x,ycoordinates and pressure of the nib and a motion analysis system for recording the limb and hand kinematics. It was observed that for line drawing in the y-direction of the tablet, finger forces were directly related to pen tip movement and finger forces were modulated in a repeatable and predictable fashion, while this was not the case for line drawing in the x-direction. This was evidence for longstanding assumptions. Wrist rotation was required for production of lines in the x-direction without excessive deviation. For writing tasks, it was observed that no two tasks performed by one subject share an identical writing process, not even when the writing results are (nearly) identical. The neuromuscular control apparatus is highly flexible and works in a coordinated fashion that allows production of nearly equal end-results by means of different mechanical and therefore neuromuscular processes. For spiral drawing, tremor that originates from the fingers, hand and arm was quantified with the transducer pen. Limb joint kinematics were displayed in three dimensions with colour coding of coordinate sample numbers. This method can reveal the origin of some forms of limb tremor. Pen grip force patterns during signature writing were found to be characteristic for subjects, which relate to their individual pen-hand interaction, resulting from fine control of distal joints. Variation between trials of the same subject was observed, revealing adaptations of the computational processes during writing. The potential for signature verification by means of finger force recording was explored.

Abstract (sommario):

Relative timing ratios are a useful measure for determining the temporal regularities of speech. The timing intervals that make up these ratios are thought to be important when creating the motor plan for an utterance (Weismer & Fennell, 1985). In fact, these ratios have been shown to be remarkably stable, even when speakers deliberately increase their rate (Tuller & Kelso, 1984; Weismer & Fennell, 1985). The constancy of these ratios also has been demonstrated in speakers with known speech timing disturbances, like the dysarthrias associated with Parkinson's and Huntington's disease (Goberman & McMillan; Ludlow, Connor, & Bassich, 1987; Weismer & Fennell, 1985), apraxia (Weismer & Fennell, 1985), and stuttering (Prosek, Montgomery, & Walden, 1988). However, a slowed rate of speech has been noted to induce variability in relative timing (Clark, 1995). The current investigation was designed to further investigate the impact of a slow rate on relative timing, as well as the impact of a different type of dysarthria on the production of these ratios. Eleven participants with MS and ten healthy controls participated. After screening the participants with MS for cognitive abilities and degree of dysathria, they produced four sentences at three different rates of speech: conversational, fast, and slow. Age-matched controls only provided the rate-controlled sentences. Relative timing ratios were extracted and an analysis of variance was conducted for each sentence to note the effects of speech rate, ratio type, and speaker condition on relative timing. The results revealed that relative timing was not constant in the slow rate for any of the participants. The noted variability in slow speech was attributed to vowel characteristics and sentence length. Finally, people with MS demonstrated larger relative timing ratios than their healthy peers when producing lengthier or motorically complex sentences. Consistent with previous research (Clark, 1995), these results indicated that relative timing ratios were not constant when rate was slowed. Hence, use of a reduced rate may have triggered the critical change required to alter relative timing. This difference may also correspond to a topological shift in the cortical planning of the utterance. These findings provide support for the use of slowed speech in the treatment of dysarthria and other speech timing disorders. It may be that slowed speech allows the speaker to access a motor plan better suited to his impaired muscular system.

Upright stance requires substantial attentional demands to integrate different forms of sensory information from the vestibular, visual, and proprioceptive systems. Haptic cues could facilitate postural synergy to augment stance stability for provision of body orientation respecting to the environment. When a suprapostural task is superimposed, attentional load multiplies to process extra sensory inputs and to update movement synergies for parallel execution of suprapostural task and stance maintenance at the same time. The purposes of the work were to investigate neural correlates for postural synergies in a dual-tasking, following addition of sensory or motor suprapostural task under the conditions of varying task constraints. The particular interests were directional effect of haptic stabilization and mutual influences of postural-suprapostural tasks. For the first study, the effects of stance pattern (bilateral stance vs. unilateral stance) and directional influence of light finger touch (medial-lateral vs. anterior-posterior) in unilateral stance upon the soleus H reflex and center of pressure (CoP) sway were studied. Subjects participated in four postural tasks, including the bilateral stance (BS), the unilateral stance without finger touch (USNT), and with finger touch in the medial-lateral direction (USML) and anterior-posterior direction (USAP). In reference to the BS, the USNT resulted in a significant stance effect on suppression of the soleus H reflex (H/Mmax) associated with enhancement of CoP sway. Among the conditions of unilateral stance, there was a marked directional effect of finger touch on modulation of the H/Mmax. A greater disinhibition of the H/Mmax and a more pronounced reduction in CoP sway in consequence to light touch in the ML direction than in the AP direction was noted (H/Mmax: USML > USAP > USNT; CoP: USML < NSAP < NSNT). In the second study, the reciprocal influences of stance pattern (bilateral stance vs. unilateral stance) and thumb-index precision grip task (static target vs. dynamic target) on postural-suprapostural tasks by manipulating task-load were studied. Subjects participated in four postural-suprapostural tasks, including static/dynamic force-matching in bilateral/unilateral stance (BS_static; US_static; BS_dynamic; US_dynamic), and two control tasks in bilateral and unilateral stances without a finger task. The normalized force error (NFE), reaction time (RT) of the finger tasks, and normalized change in center of pressure sway (ΔNCoP) were measured. For suprapostural performance, a significant interaction effect between postural and suprapostural tasks on NFE was noted (static: BS < US; dynamic: BS > US) without RT difference. For postural performance, negative ΔNCoP during unilateral stance indicated a reduction in postural sway due to added force-matching. In contrast, addition of force-matching increased postural sway during bilateral stance, but sway decreased as task-load of suprapostural task increased (BS_dynamic < BS_static). With similar design as the second study, the third study focused on investigating interplay and resource allocation for a postural-suprapostural task with a motor suprapostural goal. On top of behavioral data, event-related potentials (ERPs) and movement-related potential (MRP) were also included in the analysis. The results showed analogue interaction effects on precision of force-matching and MRP onset depending on the suprapostural or postural tasks applied (matching error & latency of MRP onset: BS_static < US_static; BS_dynamic > US_dynamic), which was assumed to prepare for optimizing suprapostural task in various stance dynamics. From the results of ERPs, N1 component was subject to stance effect with a greater amplitude around parietal cortex across both unilateral stance conditions (N1: US > BS) associated with decreased postural sway. In contrast, P2 was differentially modulated by force-matching version with smaller amplitude over the most right parietal cortex for dynamic force-matching (P2: static > dynamic). In summary, haptic modulation on the soleus H reflex and the degree of postural sway was directionally dependent. When finger touch was provided in line with prevailing postural threat, postural sway reduced together with disinhibition of the soleus H reflex. Next, performance of postural and suprapostural tasks could be differently modulated by task-load increment. MRP and RT results supported adaptive expansion of resource capacity for postural-suprapostural tasking with a motor suprapostural goal. Higher cortical structures must involve with flexible resource allocation, according to relative importance of postural and suprapostural tasks.

Abstract (sommario):

Daily activities are a source of fatigue and stress for people with lower extremity spasticity. The possible aids must be introduced while maintaining priority control by the patient. This work aims to develop such an application in the context of walking on the exoskeleton developed at the Systems Engineering Laboratory of Versailles (LISV). The application results are based on data recorded at the END-ICAP laboratory with gait sensors for healthy subjects, people with CPs, and people who had a stroke. Our contribution is the proposal of a new method of neuromotor control for a rehabilitative exoskeleton. It consists in determining and assisting the motor instructions for the movements of a patient while retaining his expertise; the assistance as needed and the detection of its intention based on a fusion of information. The results show that the proposed index characterizes the relationship of the angle difference with a reference movement for each joint. It dynamically compensates for movements efficiently and safely. This index is applicable for gait pathology studies and robotic gait assistance.

Abstract (sommario):

Low back pain is one of the most costly and common musculoskeletal disorders, affecting up to 80% of the adults in their lifetime [1]. Whole body vibration (WBV) has been found to be a major risk factor in the etiology of low back pain with WBV increasing low back disorder risk from 1.2 to 39.5 fold depending on the occupational exposure duration and magnitude [2–3]. Recent research has demonstrated that exposure to sinusoidal whole body vibration of 5 Hz leads to increased propriceptive errors and delayed neuromotor response to external perturbation [4]. These results suggest a potential mechanism for low back injuries, namely that vibration may alter neuromotor control leading to poor stabilization and control of low back motion, increasing the risk of injury. However, the methods used to assess these changes in proprioception are static measures, require a good deal of equipment and setup time, and have a high variance, particularly with removal of electrodes and sensors, that make them impractical for the industrial setting. In addition, previous studies have only examined the effect of pure sinusoidal vibration exposure rather than the mixture of frequencies seen in occupational settings. Therefore, the goal of this project was to develop a dynamic measure of lumbar sensory accuracy and neuromotor control that could be used easily in the workplace and to examine the effects of WBV vibration on the measure using an occupationally-relevant vibration exposure.

Abstract (sommario):

Low back disorders are very common affecting up to 80% of the population in their lifetime [1]. Whole body vibration (WBV) exposure has long been identified as an important risk factor for low back disorders in industrial workers [2]. A potential mechanism has been proposed by which vibration may lead to injury. Namely, vibration-induced losses in proprioception may lead to inappropriate stabilization and poor dynamic control of the lumbar spine [3]. Increases in proprioceptive errors and in delays in neuormotor response have been demonstrated with 5 Hz, vertical seatpan vibration [3]. While vertical vibration exposure is a common occupational exposure, in some cases, such as off road vehicles and construction vehicles horizontal (fore-aft) vibration may dominate [4]. In this study, the objective was to investigate how the whole body, horizontal, seatpan vibration affects muscle response and to compare these results with the previously studied whole body vertical vibration.

Abstract (sommario):

A fundamental principle of human motor behavior states that the accuracy of targeted movements relates reciprocally to their speed. This is quantified by Fitts’ Law, wherein movement time (MT) and index of difficulty (ID), the log2 ratio of target distance (A) to target height (H) has logarithmic linear relationship; MT = a+b·log2(2A/H) = a+b·ID. The slope, b (seconds/bits), measures targeting performance as the time spent at each difficulty level, expressed as bits of information to be processed by the neuromotor system [1, 2]. Fitts’ paradigm is a common measure of the kinematic performance of the upper limb, but has not been applied to its dynamic performance. Herein, we developed a dynamic speed-accuracy trade-off (DSAT) test of grip force modulation, which can be used both for assessment and training.

Abstract (sommario):

Quantitative understanding of the human neuromotor system is essential for the implementation of the future robotic therapeutic exercises. For this purpose, sensorimotor adaptations in voluntary and involuntary movements facilitated by peripheral stimulation and resultant motor-evoked potentials (MEP) must be well characterized. One such facilitation exercise is paired associative stimulation (PAS). However, effective inter-stimulus intervals between cortical and peripheral stimulations are highly variable between individuals due to different physiological characteristics. Past studies measured MEPs in a wide range of time by incrementally varying inter-stimulus intervals to find the optimal interval in a specific subject, which has been a time-consuming process. This paper develops a search algorithm based on particle filtering to estimate individualized inter-stimulus intervals for PAS with mechanical muscle tendon stimulation realized by a pneumatically-operated robotic neuromodulatory system. The particle filter-based method reduces the number of PAS trials 70%–80% in comparison to the conventional incremental method. An accelerometer attached to the robotic system that measures exact timings of tendon stimulation can further reduce the number of trials.

Abstract (sommario):

Functional Magnetic Resonance Imaging (fMRI) promises to grant motor control researchers opportunities to more directly explore neuromotor system dynamics including the role of proprioception. The effects of vibration on proprioception have been well documented including changes in perceived muscle length and lengthening velocity and altered muscle spindle organ firing [1–4]. As such, the combination of vibration of the muscle-tendon with fMRI of the brain can be used to better understand how proprioceptive signals are managed in the brain. However, the strength of the magnetic environment of the fMRI does not easily allow for traditional vibration technologies, such as a DC motor with offset mass, to be used to create the necessary vibratory stimulus to perturb the proprioceptive system. Several researchers have nonetheless successfully designed and implemented various vibration devices to probe the brain in the fMRI environment [5–7].

Abstract (sommario):

Recent evidence suggests that performance of complex locomotor tasks such as walking may be accomplished using a simple underlying organization of co-active muscles, or “modules”, which have been assumed to be structured to perform task-specific biomechanical functions (e.g., to provide body support and forward propulsion). Modular organization has been shown to explain muscle activity across a wide range of walking speeds, levels of body weight support and other combined movement tasks (e.g., [1]). However, no study has explicitly tested whether the modules would actually produce the biomechanical functions associated with them or even produce a well-coordinated movement. The purpose of this study was to generate muscle-actuated forward dynamics simulations of normal healthy walking using muscle activation modules identified using nonnegative matrix factorization as the muscle control inputs to a) assess whether the modules are sufficient to produce well-coordinated walking, and b) identify the contributions of each module to the necessary biomechanical walking sub-tasks of body support, forward propulsion and leg swing. This analysis will critically assess the functional output of the previously identified modular organization of muscle activity in walking and investigate whether it provides a foundation for the neuromotor control of human locomotion.
