Résumé :
Older adults’ postural balance is a critical domain of research as balance deficit is an important risk factor for falls that can lead to severe injuries and death. Considering the effects of ageing on sensory systems, we propose that posturographic evaluation with a force platform exploring the effect of sensory deprivation or perturbation on balance could help understand postural control alterations in the elderly. The aim of the future systematic review and meta-analysis described in this protocol is to explore the capacity of older adults to maintain their balance during sensory perturbations, and compare the effect of perturbation between the sensory channels contributing to balance. Seven databases will be searched for studies evaluating older adults’ balance under various sensory conditions. After evaluating the studies’ risk of bias, results from similar studies (i.e., similar experimental conditions and posturographic markers) will be aggregated. This protocol describes a future review that is expected to provide a better understanding of changes in sensory systems of balance due to ageing, and therefore perspectives on fall assessment, prevention, and rehabilitation.

Résumé :
Cranial sensory innervation is supplied mainly by the trigeminal nerves and by the first cervical nerves. Excitatory and inhibitory interactions among those nerve roots may occur in a mechanism called nociceptive convergence, leading to loss of somato-sensory spatial specificity. Three volunteers in an experimental trial had sterile water injected over their greater occipital nerve on one side of the neck. Pain intensity was evaluated 10, 30 and 120 s after the injection. Two of the patients reported intense pain. Trigeminal autonomic features, suggestive of parasympathetic activation, were seen associated with trigeminally distributed pain. These data add to and reinforce previous evidence of convergence of cervical afferents on the trigeminal sensory circuit.

Résumé :
Background: The proprioceptive program is directly related to neuromuscular control, which uses proprioceptive afferences to provide dynamic stabilization of the joint. Some variables can be considered risk factors for injuries, such as sprains, sudden and unexpected movement activities, simple quick changes of direction, soil type or footwear, among others. The balance training program contributes to lower injury rates and increases sports performance rate. Thus works the perception and maintenance of postural balance from information coming from sensory afferences. Objective: To perform a systematic review and verify the effect of proprioceptive training on ankle joint in athletes. Methods: A search for clinical trials was performed in the PUBMED, WEB OF SCIENCE, PEdro and SCIELO databases, the terms used for the search were “Proprioception”, “Athletic” and “Rehabilitation”, with the filters: articles published between the years of 2015 to 2020 and research in humans. Only studies published in the English language that addressed the proposed theme were included. The PEDro scale was used to evaluate the quality of studies with clinical trials, where studies with a score lower than 6/10 on the scale were excluded. Results: With the search 69 articles were found, removing the duplicates we obtained 67 eligible articles, of these, 15 studies met the inclusion and exclusion criteria. After complete analysis, 9 studies were included. Conclusion: Proprioceptive training in athletes, lasting at least three weeks with weekly protocols composed of dynamic exercises directed at individuals with ankle instability is totally effective for both joint injury prevention and rehabilitation. In addition to the increase of variables such as postural balance, coordination, postural control and functional performance.

Résumé :
In the present research we hypothesized that some particular areas or points of the body play a role in the modulation of muscular (tonic and phasic) activity. In particular, we hypothesized that subjects utilize some bodily points as constant perceptual afferences in organizing the motoric responses of the whole body. The bodily points (called perceptual focal points) could have the same role as the bow of a boat for the sailor in orienting the spatial position of the boat and its movement. We have observed the presence of these perceptual focal points in 85% of a group of undergraduate students of psychology, 21 women and 19 men, during a real and an imagined movement of the whole body. Results indicated also that, if subjects were told to modify their habitual focal points, important modifications in subjective feelings of instability, pleasure, and tension appeared.

Résumé :
Postural control during stance was investigated using the EQUITEST® system in 10 patients during recovery after an acute unilateral vestibular lesion and was compared to the time course of recovery of the static and dynamic vestibulo-ocular imbalance. During the acute phase the patients showed a characteristic pattern with normal upright stance as long as at least one accurate sensory input (visual or somatosensory) was provided and severe postural disturbances when they had to rely primarily on vestibular afferences. Both static vestibulo-ocular and vestibulo-spinal balance recovered very fast, showing basically normal results on postural testing within about 2 weeks after the lesion. Thereafter, no pathological pattern was detectable during postural testing even in patients with persistent complete unilateral vestibular lesions. Reflexive postural responses to unexpected rapid displacements of the support surface seemed not to be influenced by vestibular imbalance even in the acute phase of the lesion.

Résumé :
Sensory and sensorimotor conflicts can lead to sensory and motor efficiency disturbances, such as pain and less efficient motor control. Vertical heterophoria (VH) and vertical orthophoria (VO) are respectively the latent vertical misalignment of the eyes when the retinal images are dissociated, or not. Mild VH (< 0.57°) could indicate the presence of a conflict resulting from eye refraction problems and/or a disruption of the somaesthetic cues. Canceling the conflict(s) can immediately restore VO, making it possible to observe an improvement in the mobility of spinal and peripheral joints, the performance in the motor and balance tests after initial alternation, and a decrease in pain. The Maddox Rod Test was used to detect mild VH but doesn’t determine the sensory conflict origin. The aim of this retrospective study is to show its use as a landmark in which sensory afferent conflict could induce symptoms (i.e. pain; decreased range of motion; nonoptimal postural and motor control) and how to manage it, analyzing data from 525 subjects. The clinical process is intended to inhibit or neutralize afferent signals involved in the sensorimotor loops required by the central nervous system in motor control in order to spot the locus of conflict (stomatognathic system, pelvis, plantar afferences, piercings (body art) or/and eye refraction problems). This investigation protocol based on VH detection provides trackers for the therapeutic intervention in the management of nonspecific chronic pain, non-contact injuries, and prevention, and a key role for practitioners in the multidisciplinary management required for patients/athletes, in the world of work/health.

Résumé :
The cerebellum has a homogeneous structure and performs different computational functions such as modulation/coordination of the communication between cerebral regions, and regulation/integration of sensory information. Albeit cerebellar activity is generally associated with motor functions, several recent studies link it to various cognitive functions, including spatial navigation. In addition, cerebellar activity plays a modulatory role in different cognitive domains and brain processes. Depending on the network involved, cerebellar damage results in specific functional alterations, even when no function loss might be detected. In the present review, we discuss evidence of brainstem degeneration and of a substantial reduction of neurons in nuclei connected to the inferior olivary nucleus in the early stages of Alzheimer’s disease. Based on the rich patterns of afferences from the inferior olive nucleus to the cerebellum, we argue that the subtle alterations in spatial navigation described in the early stages of dementia stem from alterations of the neuromodulatory functions of the cerebellum.

Résumé :
Conventional one-sensor theory (one afferent fiber connects to a single sensor) categorizes the bronchopulmonary mechanosensors into the rapidly adapting receptors (RARs), slowly adapting receptors (SARs), or intermediate adapting receptors (IARs). RARs and SARs are known to sense the rate and magnitude of mechanical change, respectively; however, there is no agreement on what IARs sense. Some investigators believe that the three types of sensors are actually one group with similar but different properties and IARs operate within that group. Other investigators (majority) believe IARs overlap with the RARs and SARs and can be classified within them according to their characteristics. Clearly, there is no consensus on IARs function. Recently, a multiple-sensor theory has been advanced in which a sensory unit may contain many heterogeneous sensors, such as both RARs and SARs. There are no IARs. Intermediate adapting unit behavior results from coexistence of RARs and SARs. Therefore, the unit can sense both rate and magnitude of changes. The purpose of this review is to provide evidence that the multiple-sensor theory better explains sensory unit behavior.

Texte intégral
Résumé :
Les technologies numériques sont omniprésentes dans le quotidien des enfants et adolescents. Les technologies interactives comme les tablettes tactiles semblent particulièrement attractives et faciles d’utilisation, apportant des bénéfices sur les apprentissages scolaires. La question se pose alors de savoir si ces avantages peuvent s’observer également pour d’autres formes d’activité ne faisant pas l’objet d’un apprentissage. Dans ce cadre, nous nous intéresserons aux activités créatives. Bien que la créativité soit conçue comme un phénomène de nature multifactorielle, les composantes sensorimotrices n’ont été que très peu intégrées dans le processus créatif. Pourtant, Dietrich et Haider (2015) ont récemment suggéré que le processus permettant de générer une idée créative emprunterait le même mécanisme que celui utilisé pour contrôler une action réalisée ou imaginée au travers de la prédiction sensorimotrice. Les afférences sensorielles étant centrales dans le contrôle de l’action sensorimotrice, elles pourraient être considérées comme des facteurs constitutifs de la créativité. Selon cette proposition, il pourrait être suggéré que modifier les afférences sensorielles disponibles dans une tâche pourrait moduler la créativité. Dans cette thèse, nous interrogeons cette relation entre créativité et sensorimotricité. Au travers de 4 études expérimentales, nous avons fait varier les afférences sensorielles disponibles dans une tâche créative en faisant dessiner des enfants et adolescents de 6 à 15 ans sur tablette tactile au doigt, au stylet, et sur papier au stylo. Les résultats montrent effectivement qu’augmenter les afférences sensorielles en utilisant le doigt sur tablette tactile améliore l’originalité à tout âge. En revanche, réduire les afférences sensorielles lors de l’utilisation du stylet n’amène pas aux mêmes effets sur les performances d’originalité selon l’âge des participants. Chez les enfants de 6-7 ans, utiliser le stylet sur tablette tactile ne modifie pas les performances d’originalité. Après 8 ans, les enfants réalisent des dessins plus originaux au stylet sur tablette tactile qu’au stylo sur papier. L’effet bénéfique du stylet sur les performances créatives à partir de cet âge pourrait s’expliquer par l’acquisition de la capacité à compenser la perte d’afférences sensorielles qui permet de maximiser les informations sensorielles, apportant ainsi des bénéfices sur l’originalité. Ces bénéfices de la tablette tactile s’observent également chez des adolescents qui, du fait de troubles du comportement, présentent des difficultés dans la mobilisation de leurs capacités cognitives. De plus, ces adolescents rapportent une préférence majoritaire pour l’utilisation du support tactile en comparaison du support papier, qui serait lié à une plus grande mobilisation sensorielle dans la production des gestes graphiques sur l’interface. Nous discutons de l’implication de ces résultats pour la nature du processus créatif et son développement, ainsi que l’utilisation d’afférences sensorielles pour aider les enfants et adolescents typiques, comme atypiques, à mobiliser plus efficacement leurs capacités cognitives
Digital technologies are omnipresent in children and adolescents’ daily life. Interactive technologies such as touchscreens seem particularly attractive and easy to use, bringing benefits on school learning. The question arises whether these benefits can be also observed with other types of activities that are not subject to learning. In this work, we will specifically focus on creative framework. Although creativity is conceived as a multifactorial phenomenon, sensorimotor components have been very little integrated in creative process. Yet, Dietrich and Haider (2015) recently suggested that the process allowing to generate a creative idea would use the same mechanism than the one used to control a real or imagined action through sensorimotor prediction. Thereby, sensory afferences being central in sensorimotor action control, could be considered as one of the constitutive factors of creativity. In this thesis, we question this relationship between creativity and sensorimotricity. Through 4 experimental studies, we varied available sensory afferences in a creative drawing task by asking 6 to 15 years old children and adolescents to draw on touchscreen with finger, with stylus, and on paper with a pen. The results indeed show that enhancing sensory afferences with finger on touchscreen enhances originality at all age. However, lowering sensory afferences with the use of a stylus does not bring to the same effects on originality performance according to the age of participants. In children aged 6-7 years old, using a stylus on tablet does not modify originality performances. After 8 years old, children realize more original drawings with the use of a stylus on touchscreen than with a pen on paper. The observed benefits on creative performances from this age could be explained by the acquired capacity to compensate a sensory loss, that allow to maximize sensory information, thus leading to originality benefits. These benefits with finger and with stylus are also observed with adolescents who, because of disruptive behavior disorder, show difficulties in mobilizing cognitive capacities. Qualitative data acquired from adolescents with this trouble yields a major preference for tactile rather than paper support, that would be linked to a higher sensory mobilization in the production of graphic gestures on the interface. We discuss of the implication of these results for the creative process nature and its development, as well as using sensory afference to help typical and atypical children and adolescents to mobilize cognitive capacities more efficiently

Résumé :
During dexterous manipulation with the fingertips, forces are applied to objects' surfaces. To achieve grasp stability, these forces must be appropriate given the properties of the objects and the skin of the fingertips, and the nature of the task. It has been demonstrated that tactile sensors in the fingertips provide crucial information about both object properties and mechanical events critical for the control of fingertip forces, while in certain tasks vision may also contribute to predictions of required fingertip actions. This thesis focuses on two specific aspects of the sensory control of manipulation: (i) how individual fingers are controlled for grasp stability when people restrain objects subjected to unpredictable forces tangential to the grasped surfaces, and (ii) how tactile sensors in the fingertips encode direction of fingertip forces and shape of surfaces contacted by the fingertips. When restraining objects with two fingers, subjects adjust the fingertip forces to the local friction at each digit-object interface for grasp stability. This is accomplished primarily by partitioning the tangential force between the digits in a way that reflects the local friction whereas the normal forces at the involved digits are scaled by the average friction and the total load. The neural control mechanisms in this task rely on tactile information pertaining to both the friction at each digit-object interface and the development of tangential load. Moreover, these mechanisms controlled the force application at individual digits while at the same time integrating sensory inputs from all digits involved in the task. Microneurographical recordings in awake humans shows that most SA-I, SA-II and FA-I sensors in the distal phalanx are excited when forces similar to those observed during actual manipulation are applied to the fingertip. Moreover, the direction of the fingertip force influences the impulse rates in most afferents and their responses are broadly tuned to a preferred direction. The preferred direction varies among the afferents and, accordingly, ensembles of afferents can encode the direction of fingertip forces. The local curvature of the object in contact with the fingertip also influenced the impulse rates in most afferents, providing a curvature contrast signals within the afferent populations. Marked interactions were observed in the afferents' responses to object curvature and force direction. Similar findings were obtained for the onset latency in individual afferents. Accordingly, for ensembles of afferents, the order by which individual afferents initially discharge to fingertip events effectively represents parameters of fingertip stimulation. This neural code probably represents the fastest possible code for transmission of parameters of fingertip stimuli to the CNS.

Résumé :
The first part of my thesis involves an investigation into mechanisms underlying the presynaptic regulation of transmitter release from myelinated hindlimb sensory afferents in rodents. The central hypothesis is that in addition to chemical transmission in spinal neuronal networks, electrical synapses formed by connexins are critically involved in presynaptic inhibition of large diameter sensory afferents. Subsequent sections of the thesis present a detailed examination of the distribution of connexins in the rodent spinal cord with a particular emphasis on the neuronal connexin, Cx36. Connexin36 (Cx36) is widely believed to be the protein forming the neuronal gap junctions that create electrical synapses between mammalian neurons in many areas of the central nervous system (Condorelli et al 1998). The first part of thesis concerns a previously unknown role of neuronal connexins in interneurone pathways involved in presynaptic control of synaptic transmission in the lumbar spinal cord of rodents. As far as we are aware, the idea that electrical contacts between spinal neurones contribute to spinal presynaptic inhibition is a novel hypothesis. Evidence will be presented: 1) that Cx36 is present in regions of the spinal cord containing interneurones involved in presynaptic inhibition, 2) that the lack of Cx36 in Cx36-/- knockouts mice results in a severe impairment of presynaptic inhibition, and 3) that blocking gap junctions pharmacologically in wild type mice impairs presynaptic inhibition. The exploration of this hypothesis will involve a combination of electrophysiological and immunohistochemical approaches in juvenile wild-type and knockout mice lacking Cx36, as well as immunohistochemical observations in adult rodents. This first section of the thesis begins with the development of a preparation in which several measures of presynaptic inhibition described in the in vivo adult cat preparation can be examined in vitro in young mice. The following sections of the thesis describe the distribution and features of Cx36 on neurones in mice and rats of different ages in four parts. The first will show that Cx36 is the only connexin associated with spinal neurons and refutes claims in the literature about the existence of a variety of connexions on spinal neurons. The second part will show that while gap junctions between some spinal neurons are only a transient developmental phenomenon, they persist in abundance in adult animals. The third part will present evidence of a previously unsuspected III association of Cx36 gap junctions at the chemical synapse between muscle afferent fibres and motoneurones. Specifically, an association between Cx36 and the glutamate transporter used in primary afferents, Vglut1 will be described. To our knowledge these results are the first to suggest the existence of mixed (electrical and chemical) synapses between primary afferents and motoneurones in the mature mammalian spinal cord. The final part of the thesis will describe the presence of Cx36 gap junctions on adult sacral motoneurones involved in control of sexual, urinary and defecation functions in the rodent.

Résumé :
La chute chez les seniors constitue un problème de santé publique. Citée comme la seconde cause de décès accidentel dans le monde, elle concerne un tiers des Français de plus de 65 ans. Les séquelles physiques et fonctionnelles qui en résultent, les conséquences psychosociales nuisibles pour la qualité de la vie, la perte d'autonomie et son coût de prise en charge justifient l'attention qui lui est actuellement portée. Du point de vue du chercheur, les interprétations sous-jacentes à la surexposition des personnes âgées au risque de chute restent controversées, notamment parce que la compréhension de la coordination dynamique corporelle et de l'implication corticale lors du contrôle de l'équilibre est encore limitée. L'étude de la chute et des mécanismes qui y conduisent présente donc un double intérêt, fondamental et sociétal. Une chute survient si deux conditions sont réunies. La première est la perte initiale de l'équilibre, un 'pré-requis' qui peut toucher la population entière dans son quotidien. La seconde est un échec des mécanismes de rééquilibration, c'est à dire de la stratégie de réponse mise en œuvre pour compenser la déstabilisation : comment s'opère la sélection d'une stratégie de rattrapage, à partir de quelle appréciation du contexte et des informations sensorielles disponibles est-elle choisie ? qu'est ce qui assure son opérationnalité et garantit le rattrapage ou signe au contraire son échec ?...Pour répondre à ces questions, nous nous sommes donc intéressés à ce moment critique où il est encore possible de modifier l'issue finale par des ajustements posturaux et des actions motrices rapides et adéquats chez une population de jeunes adultes. La première étude est une analyse globale de la phase précoce d'une chute -abrégée par un harnais- (soit quelques centaines de millisecondes après la perturbation), afin d'évaluer la capacité du sujet à réagir à une perturbation imprévue et de développer des stratégies garantissant une protection efficace. Cette première étape se propose d'identifier les indicateurs discriminants et prédictifs d'une chute et d'un rattrapage au niveau neurophysiologique et biomécanique. Cette étude a également permis de mettre en évidence la présence d'un délai temporel incompressible appelé " phase passive ", source de contraintes spatio-temporelles à l'expression complète d'une réponse posturale adaptée. Dans la seconde étude, de modélisation, nous avons élaboré un modèle mécanique personnalisé, construit à partir de radiographies tridimensionnelles non invasives du corps entier. Cette modélisation nous a permis d'analyser la contribution relative de propriétés biomécaniques passives et des synergies musculaires actives en jeu pendant les perturbations récupérables de l'équilibre ou non en comparant les résultats expérimentaux ('réels') obtenus à l'aide d'un dispositif asservi pour provoquer des chutes de plain-pied et la réponse théorique prédite ('simulée') à l'aide du modèle. Les résultats obtenus permettent de confirmer que le comportement du corps est en phase précoce-dicté par ses propriétés mécaniques, et peut être assimilé à un modèle simplifié. Après avoir mis en évidence l'existence d'une phase inertielle d'une durée équivalente à la moitié du temps disponible avant l'impact, notre questionnement s'est orienté vers le traitement de l'information en-cours lors de cette phase afin d'évaluer la contribution corticale alors que la réponse posturale évolue. La troisième étude consiste principalement à appréhender la charge cognitive impliquée dans le contrôle sensori-moteur, en particulier lors d'une chute, à l'aide du paradigme de double-tâche. En conclusion, à travers une approche pluridisciplinaire, les résultats obtenus dans cette thèse permettent d'émettre des recommandations intéressantes pour une prévention et une rééducation adaptée dans le but de contribuer à l'amélioration de la qualité de vie des personnes âgées.

Résumé :
Abstract: Postural control is a complex process involving sensory inputs from visual, vestibular, proprioceptive and tactile receptors, processed by the central nervous system (CNS). Sensory information provided by muscle and cutaneous afferents in the foot optimize the ability to stand upright and control the postural sway. The foot, as a direct and often only interface between the body and the ground, constitutes an essential functional whole participating in mechanisms of postural control and regulation, allowing the body to sense and interact with the surrounding environment. Among many somatosensory stimulations designed to improve balance, wearing shoe insoles presents one of the easiest and most cost-effective ways. This method can be used both amongst elderly population for fall prevention and amongst athletes to reach better performance and furthermore prevent injuries. With the growing interest in insole use, several prototypes have been developed to monitor movement during day to day use. For therapeutic purposes, the type of insoles used in the studies was often not clarified, and the term insole was used as a general term.The proposed theme of the discussion is to review already existing data on insole use for treatment of postural balance. Keywords: Postural control; Postural sway balance; Insoles; Foot stimulation
