Description

    système de stimulations tactilestactile stimulation system DOMAINE DE L'INVENTIONFIELD OF THE INVENTION
  • La présente invention concerne les systèmes de stimulation tactile du corps d’une personne. Plus particulièrement elle concerne les systèmes permettant d’améliorer la perception tactile d’une ou plusieurs zones du corps via la stimulation tactile d’une ou plusieurs autres zones.The present invention relates to systems for tactile stimulation of a person's body. More particularly, it relates to systems making it possible to improve the tactile perception of one or more areas of the body via the tactile stimulation of one or more other areas.
    • ETAT DE LA TECHNIQUESTATE OF THE ART
  • On connait des systèmes de stimulations tactiles d’une zone du corps d’une personne, par exemple d’une zone du visage. Une stimulation tactile est une stimulation de la peau, au niveau de la zone, réalisée par un actionneur, par exemple un actionneur tactile.Systems are known for tactile stimulation of an area of a person's body, for example an area of the face. A tactile stimulation is a stimulation of the skin, at the level of the zone, carried out by an actuator, for example a tactile actuator.
  • Par stimulation tactile on comprend une stimulation d’une partie du corps pendant une durée établie. Ainsi une stimulation tactile est une stimulation de la peau, au niveau d’une ou plusieurs zones du corps, qui est réalisée par un actionneur. Cet actionneur peut par exemple être posé sur ou mis en contact avec cette zone, laquelle peut rester immobile ou bouger pendant toute la durée de la stimulation. Aucun mouvement, action ni exercice n’est demandé car l’amélioration est atteinte de façon entièrement passive. On utilise aussi l’expression stimulation somatosensorielle ou stimulation tactile passive.By tactile stimulation we understand a stimulation of a part of the body for an established duration. Thus a tactile stimulation is a stimulation of the skin, at the level of one or more areas of the body, which is carried out by an actuator. This actuator can for example be placed on or brought into contact with this zone, which can remain stationary or move throughout the duration of the stimulation. No movement, action or exercise is required because the improvement is achieved entirely passively. The term somatosensory stimulation or passive tactile stimulation is also used.
  • Un des domaines d’application de ces systèmes est le domaine médical, par exemple pour soigner les déficits sensorimoteurs qui sont communs à plusieurs pathologies ainsi qu’au vieillissement.One of the fields of application of these systems is the medical field, for example to treat sensorimotor deficits which are common to several pathologies as well as to aging.
  • Ces déficits sensorimoteurs peuvent être provoqués par un accident vasculaire cérébral (AVC), qui est la première cause de séquelles engendrant des déficits sensorimoteurs. D’autres lésions cérébrales, par exemple d’origine traumatique ou hémorragique, ou encore celles induites par des pathologies neurodégénératives, peuvent provoquer des séquelles sensorimotrices du même type. Enfin, des déficits sensorimoteurs peuvent également affecter des personnes ayant subi une immobilisation temporaire d’un membre.These sensorimotor deficits can be caused by a cerebrovascular accident (CVA), which is the first cause of sequelae leading to sensorimotor deficits. Other brain lesions, for example of traumatic or hemorrhagic origin, or those induced by neurodegenerative pathologies, can cause sensorimotor sequelae of the same type. Finally, sensorimotor deficits can also affect people who have undergone temporary immobilization of a limb.
  • Parmi les déficits sensorimoteurs, on peut citer la perte de perception tactile d’une zone du corps. Cette perte peut engendrer un impact négatif sur plusieurs fonctions comme, par exemple, la saisie et manipulation des objets (ex, membre supérieurs), sur les mouvements oro-faciaux (ex, visage) et le maintien de l’équilibre postural (ex, contrôle sensorimoteur de membres inferieurs). La rééducation de déficits sensorimoteurs est réalisable par l’amélioration de cette perception tactile.Among the sensorimotor deficits, we can cite the loss of tactile perception of an area of the body. This loss can have a negative impact on several functions such as, for example, the grasping and manipulation of objects (eg, upper limbs), on orofacial movements (eg, face) and the maintenance of postural balance (eg, sensorimotor control of lower limbs). The rehabilitation of sensorimotor deficits is possible by improving this tactile perception.
  • De plus, ces systèmes de stimulations tactiles peuvent être utilisés pour améliorer la perception tactile d’une personne ne présentant pas de déficit préalable mais souhaitant augmenter sa perception tactile pour améliorer ses performances sensorimotrices : par exemple les chirurgiens, les musiciens etc.In addition, these tactile stimulation systems can be used to improve the tactile perception of a person who does not have a prior deficit but wishes to increase their tactile perception to improve their sensorimotor performance: for example surgeons, musicians, etc.
  • Ces systèmes de stimulations tactiles peuvent être utilisés par toute personne voulant augmenter sa fonctionnalité manuelle pour un objectif personnel/ludique et pas spécifiquement professionnel, par exemple dans le cas des joueurs de jeux vidéo, des musiciens et sportifs amateurs, des personnes voulant améliorer leurs performances dans des activités spécifiques comme par exemple lire le Braille, etc.These tactile stimulation systems can be used by anyone wishing to increase their manual functionality for a personal/fun objective and not specifically professional, for example in the case of video game players, musicians and amateur sportsmen, people wishing to improve their performance in specific activities such as reading Braille, etc.
  • Ces systèmes de stimulations tactiles peuvent être utilisés dans l’industrie, notamment de la cosmétologie et du textile. Il est reconnu que le diffèrent degré de perception tactile, sur les mains ainsi que sur le visage, peut moduler le choix dans l’application de certains produits cosmétiques sur la peau par rapport à des autres, ainsi que le choix dans l’achat de produits textiles. Pour cela, ces systèmes améliorant la perception tactile pourront être utilisés par les professionnels du secteur pour cibler et orienter les choix des clients.These tactile stimulation systems can be used in industry, particularly in cosmetology and textiles. It is recognized that the different degree of tactile perception, on the hands as well as on the face, can modulate the choice in the application of certain cosmetic products on the skin compared to others, as well as the choice in the purchase of textile products. To do this, these systems that improve tactile perception can be used by professionals in the sector to target and guide customer choices.
  • La demande de brevet US 2019/117933 A1 décrit des dispositifs et procédés de stimulation cérébrale par stimulations tactiles de la tête de l’utilisateur, les stimulations tactiles pouvant être des séries successives d’impulsions dont la fréquence peut varier dans le temps.Patent application US 2019/117933 A1 describes devices and methods for brain stimulation by tactile stimulation of the user's head, the tactile stimulation possibly being successive series of pulses whose frequency may vary over time.
  • Les demandes de brevets US 2007/208280 A1 et US 2008/020972 A1 décrivent d’autres exemples de dispositifs pour générer des stimulations tactiles.Patent applications US 2007/208280 A1 and US 2008/020972 A1 describe other examples of devices for generating tactile stimuli.
  • Les systèmes actuels nécessitent la stimulation tactile de la zone pour laquelle la perception tactile doit être améliorée. Or il n’est parfois pas possible ou efficace de réaliser la stimulation tactile sur la zone dont la performance est à améliorer, notamment lorsque cette zone est inaccessible, soit temporairement, comme par exemple les mains d’une personne portant des gants, telle qu’un chirurgien, soit de manière plus durable, comme par exemple une zone lésée.Current systems require tactile stimulation of the area for which tactile perception must be improved. However, it is sometimes not possible or effective to perform tactile stimulation on the area whose performance is to be improved, in particular when this area is inaccessible, either temporarily, such as for example the hands of a person wearing gloves, such as 'a surgeon, or in a more durable way, such as for example an injured area.
  • Il y a donc un besoin de systèmes de stimulation tactiles permettant une amélioration de la perception tactile d’une ou plusieurs zones en réalisant des stimulations tactiles sur une ou plusieurs autres zones.There is therefore a need for tactile stimulation systems allowing an improvement in the tactile perception of one or more zones by performing tactile stimulations on one or more other zones.
  • A cet effet on prévoit, selon l'invention, un système de stimulations tactiles. Ce système est configuré pour générer des stimulations tactiles dont des instants de génération suivent une loi de poisson de paramètre lambda compris entre 0,5 et 1,5.To this end, provision is made, according to the invention, for a tactile stimulation system. This system is configured to generate tactile stimuli whose instants of generation follow a Poisson law with a lambda parameter between 0.5 and 1.5.
  • Ce système permet d’améliorer la perception tactile de la zone d’un membre, par exemple un membre supérieur, et plus particulièrement de la main, via la stimulation d’une autre partie du corps, par exemple le visage, facultativement en sus de la stimulation locale classique qui consiste à stimuler directement la zone lésée dans le cas d’une application au domaine médical. Comme indiqué ci-dessus, la zone dont la perception tactile est à améliorer peut être une zone inaccessible temporairement ou de manière plus durable.This system makes it possible to improve the tactile perception of the zone of a limb, for example an upper limb, and more particularly of the hand, via the stimulation of another part of the body, for example the face, optionally in addition to conventional local stimulation which consists of directly stimulating the injured area in the case of an application in the medical field. As indicated above, the zone whose tactile perception is to be improved may be an inaccessible zone temporarily or in a more lasting manner.
  • En effet il a été remarqué qu’une séquence de stimulations tactiles générées à des instants suivant une loi de poisson de paramètre lambda compris entre 0,5 et 1,5 et appliquées sur une zone du corps d’une personne permet d’améliorer la perception tactile de la zone d’application mais aussi d’une autre zone du corps.Indeed, it has been observed that a sequence of tactile stimuli generated at instants following a Poisson law with a lambda parameter between 0.5 and 1.5 and applied to a zone of a person's body makes it possible to improve the tactile perception of the area of application but also of another area of the body.
  • Par exemple, cette stimulation du visage permet d’améliorer la perception tactile du visage mais aussi du membre supérieur.For example, this facial stimulation improves the tactile perception of the face but also of the upper limb.
  • Ce système est utilisable pour la rééducation de personnes ayant subi un AVC. En effet, il permet de stimuler une région intacte (par exemple le visage dont la perception tactile est généralement préservée chez les personnes ayant eu un AVC) dans le but d’améliorer la perception tactile et donc la rééducation sensorimotrice de la région affectée (par exemple la main). Ce système offre l’avantage de faire bénéficier la région affectée des effets des stimulations tactiles, sans que l’amélioration de la perception tactile ne soit affectée par les dommages liés à la pathologie, car les stimulations tactiles sont réalisées sur une région intacte.This system can be used for the rehabilitation of people who have suffered a stroke. Indeed, it makes it possible to stimulate an intact region (for example the face whose tactile perception is generally preserved in people who have had a stroke) with the aim of improving tactile perception and therefore the sensorimotor rehabilitation of the affected region (by example the hand). This system offers the advantage of allowing the affected region to benefit from the effects of tactile stimulation, without the improvement in tactile perception being affected by the damage linked to the pathology, since the tactile stimulation is performed on an intact region.
  • De plus, la partie du corps qui a été l’objet de la stimulation présente également une amélioration de la perception tactile. Ainsi une seule et même stimulation permet l’amélioration de deux zones, celle stimulée (par exemple le visage) et une autre à distance (par exemple la main). In addition, the part of the body that was the object of stimulation also shows an improvement in tactile perception. Thus, one and the same stimulation allows the improvement of two areas, the one stimulated (for example the face) and another at a distance (for example the hand).
  • Dans un mode de réalisation du système, une durée séparant deux instants de génération de deux stimulations tactiles successives est comprise entre 0,083 s et 3,013 s.In one embodiment of the system, a duration separating two instants of generation of two successive tactile stimulations is between 0.083 s and 3.013 s.

Ces stimulations sont dites passives, car elles ne nécessitent ni attention ni tâche de la part de la personne les recevant.The represents a system 101 of tactile stimulations of the invention. These stimulations are said to be passive, because they require neither attention nor task on the part of the person receiving them.
  • Ce système 101 comprend un actionneur 102 qui est un dispositif permettant de générer les stimulations tactiles et une unité de commande 103 reliée à l’actionneur 102 et configurée pour commander l’actionneur 102 afin qu’il génère les stimulations. Cet actionneur 102 est par exemple un actionneur tactile.This system 101 comprises an actuator 102 which is a device making it possible to generate the tactile stimulations and a control unit 103 connected to the actuator 102 and configured to control the actuator 102 so that it generates the stimulations. This actuator 102 is for example a tactile actuator.
  • L’unité de commande 103 est un dispositif électronique, tel qu'un ordinateur, un dispositif électronique de poche (tel qu'un téléphone portable, un téléphone intelligent ou smartphone en anglais), un baladeur numérique, ou des dispositifs équivalents. L’unité de commande 103 comprend une unité de traitement, un dispositif de mémorisation et un module de stockage d’électricité 104. L’unité de commande 103 peut être connecté à un ordinateur (un autre ordinateur, si l’unité de commande 103 est déjà un ordinateur) pour configurer les paramètres de stimulation. L’unité de commande 103 dispose d’un système d’activation ON/OFF pour déclencher/mettre en pause/arrêter les stimulations tactiles délivrées par l’actionneur 102 relié à l’unité de commande 103, ainsi que d’un système de réglage pour réduire/augmenter l’intensité des stimulations tactiles. The control unit 103 is an electronic device, such as a computer, a pocket electronic device (such as a mobile phone, a smart phone or smartphone in English), a digital walkman, or equivalent devices. The control unit 103 comprises a processing unit, a memory device and an electricity storage module 104. The control unit 103 can be connected to a computer (another computer, if the control unit 103 is already a computer) to configure stimulation settings. The control unit 103 has an ON/OFF activation system for triggering/pausing/stopping the tactile stimulation delivered by the actuator 102 connected to the control unit 103, as well as a adjustment to reduce/increase the intensity of tactile stimulation.
  • L’unité de traitement peut être un processeur ou un microcontrôleur à usage général ou spécifique pour contrôler l’actionneur tactile 102, afin qu’il génère les stimulations tactiles.The processing unit can be a general or specific purpose processor or microcontroller to control the touch actuator 102, so that it generates the touch stimuli.
  • Par exemple, le processeur peut être un circuit intégré spécifique à une application (Application-Specific Integrated Circuit pour ASIC en anglais) permettant de gérer et de contrôler les stimulations tactiles générées par l’actionneur 102.For example, the processor can be an integrated circuit specific to an application ( Application-Specific Integrated Circuit for ASIC in English) making it possible to manage and control the tactile stimulations generated by the actuator 102.
  • L’unité de commande 103 est en particulier configurée pour commander la durée, la forme, la fréquence et les instants de réalisation des stimulations tactiles générées par l’actionneur 102. La configuration de ces différents paramètres de stimulation est effectuée par connexion à un ordinateur. Dans un autre mode de réalisation, l’ordinateur est intégré dans l’unité de commande 103.The control unit 103 is in particular configured to control the duration, the form, the frequency and the instants of realization of the tactile stimulations generated by the actuator 102. The configuration of these various stimulation parameters is carried out by connection to a computer . In another embodiment, the computer is integrated into the control unit 103.
  • Le dispositif de mémorisation peut être fixe ou amovible et comporter différentes unités mémoires pouvant inclure une combinaison d’unités permettant un stockage volatile et non volatile. Le dispositif de mémorisation est configuré pour stocker un code logiciel utilisable par le processeur pour contrôler l’actionneur 102. Il est aussi configuré pour stocker les paramètres représentatifs des stimulations tactiles.The storage device may be fixed or removable and comprise different memory units which may include a combination of units allowing volatile and non-volatile storage. The memory device is configured to store software code usable by the processor to control the actuator 102. It is also configured to store the parameters representative of the tactile stimulations.
  • Le module de stockage 104 d’électricité est, par exemple, un compartiment pour des batteries (power bank en anglais) ou des piles. Ce module permet d’alimenter en électricité l’unité de commande 103 et l’actionneur 102. The electricity storage module 104 is, for example, a compartment for batteries ( power bank in English) or cells. This module is used to supply electricity to the control unit 103 and the actuator 102.
  • L’unité de commande 103 et l’actionneur 102 sont reliés par des liaisons, afin d’échanger des commandes et/ou des signaux représentatifs des stimulations tactiles à appliquer. Ces liaisons peuvent aussi permettre l’alimentation électrique de l’actionneur 102 par l’unité de commande 103.The control unit 103 and the actuator 102 are connected by links, in order to exchange commands and/or signals representative of the tactile stimulations to be applied.

  • Ainsi l’unité de commande 103 peut réaliser un procédé de commande de l’actionneur 102 pour qu’il génère des stimulations tactiles dont des instants de génération suivent une loi de poisson de paramètre lambda compris entre 0,5 et 1, 5 et de manière avantageuse entre 1,15 et 1,2. L’unité de commande 103 peut comprendre un produit programme d’ordinateur comprenant des instructions de code de programme pour l’exécution du procédé de commande de l’actionneur 102.Thus the control unit 103 can carry out a method of controlling the actuator 102 so that it generates tactile stimuli whose generation instants follow a Poisson law with a lambda parameter between 0.5 and 1.5 and of advantageously between 1.15 and 1.2.

  • L’actionneur 102 peut utiliser un mécanisme, électrique, vibratoire ou de toute autre nature dans la mesure où il peut générer des stimulations tactiles. Par exemple l’actionneur 102 peut générer la stimulation tactile par génération d’un flux d’air comprimé, d’un signal auditif ou d’une onde magnétique. Dans un mode de réalisation, l’actionneur 102 peut utiliser un système vibratoire permettant de réaliser des stimulations sur la peau, lorsque ce système vibratoire est placé en contact sur la peau. Ce système vibratoire peut être par exemple par un haut-parleur, qui est un transducteur destiné à produire des stimulations à partir d'un signal électrique.The actuator 102 can use a mechanism, electric, vibratory or of any other nature insofar as it can generate tactile stimulations. For example, the actuator 102 can generate tactile stimulation by generating a flow of compressed air, an auditory signal or a magnetic wave. In one embodiment, the actuator 102 can use a vibratory system making it possible to perform stimulations on the skin, when this vibratory system is placed in contact with the skin. This vibratory system can be for example by a loudspeaker, which is a transducer intended to produce stimulations from an electric signal.
  • Dans un autre mode de réalisation, l’actionneur 102 reçoit des impulsions ou commandes permettant de commander l’actionneur 102 afin qu’il génère les stimulations sur la peau, par effet d’un système vibratoire interne, à partir d'un signal électrique. L’ensemble des impulsions/commandes provoque et représente la stimulation tactile. Dans un mode réalisation les différents éléments de l’unité de commande 103 et de l’actionneur 102 sont positionnés sur un même support (par exemple sur un même circuit imprimé).In another embodiment, the actuator 102 receives impulses or commands making it possible to control the actuator 102 so that it generates the stimulations on the skin, by effect of an internal vibratory system, from an electrical signal . All impulses/commands cause and represent tactile stimulation. In one embodiment, the various elements of the control unit 103 and of the actuator 102 are positioned on the same support (for example on the same printed circuit).
  • Dans un mode de réalisation l’unité de commande 103 comprend un baladeur numérique ou un dispositif équivalent qui génère un signal représentatif de la stimulation. L’unité de commande 103 comprend aussi un amplificateur, par exemple un amplificateur audio, connecté au baladeur numérique pour amplifier le signal et le transmettre à l’actionneur 102.In one embodiment the control unit 103 comprises a digital walkman or an equivalent device which generates a signal representative of the stimulation. The control unit 103 also includes an amplifier, for example an audio amplifier, connected to the digital walkman to amplify the signal and transmit it to the actuator 102.
  • Les stimulations tactiles sont généralement appliquées sur le visage ou une autre zone de la peau à l’aide de l’actionneur 102. Dans un mode de réalisation l’actionneur 102 comprend un support non adhésif. Dans ce cas, l’actionneur 102 est appuyé à la zone cible et les stimulations tactiles sont délivrées par exemple par contact entre l’actionneur 102 et la zone cible. Dans ce cas, l’actionneur 102 est appuyé à la zone cible du visage grâce à un support adapté au visage. Dans un mode de réalisation le support est adhésif et/ou bi-adhésif et l’actionneur 102 est fixé à la zone cible du visage grâce à cet adhésif. La zone cible est, par exemple, le nez, la lèvre supérieure, la lèvre inférieure, la joue, l’une des oreilles ou toute autre zone ou partie du corps.Tactile stimulations are typically applied to the face or other area of skin using actuator 102. In one embodiment actuator 102 includes a non-adhesive backing. In this case, the actuator 102 is pressed on the target zone and the tactile stimulations are delivered for example by contact between the actuator 102 and the target zone. In this case, the actuator 102 is supported on the target area of the face thanks to a support adapted to the face. In one embodiment, the support is adhesive and/or bi-adhesive and the actuator 102 is fixed to the target area of the face thanks to this adhesive. The target area is, for example, the nose, upper lip, lower lip, cheek, one of the ears or any other area or part of the body.
  • Dans un mode de réalisation, l’actionneur 102 n’est pas en contact avec la zone de la peau, par exemple un patch peut être présent entre la zone de la peau et l’actionneur 102.In one embodiment, the actuator 102 is not in contact with the skin area, for example a patch may be present between the skin area and the actuator 102.
  • Ces stimulations tactiles permettent de modifier la perception de la région stimulée ainsi que d’au moins une autre région non stimulée. These tactile stimuli make it possible to modify the perception of the stimulated region as well as of at least one other non-stimulated region.
  • L’unité de commande 103 commande l’actionneur 102 pour générer les stimulations tactiles. Ces stimulations tactiles sont paramétrées par :The control unit 103 controls the actuator 102 to generate the tactile stimulations. These tactile stimulations are parameterized by:
  • - la loi suivie par les instants temporels de génération des stimulations tactiles, cette loi est une loi de Poisson avec un paramètre lambda compris entre 0,5 et 1,5. En s’éloignant de cette plage de paramètre, la distribution des stimulations tactiles ne respecte plus la distribution voulue. - the law followed by the temporal instants of generation of the tactile stimuli, this law is a Poisson law with a lambda parameter comprised between 0.5 and 1.5. By moving away from this parameter range, the distribution of tactile stimuli no longer respects the desired distribution.
  • - la durée maximale, minimale et moyenne de l’intervalle temporel séparant deux stimulations tactiles (ISI ou InterStimulus Intervals en anglais), cette durée maximale est de 3,013s, cette durée minimale est de 0,083s et cette durée moyenne est de 0,856s. Il est avantageux que les intervalles temporels respectent ces durées établies afin de déclencher efficacement les effets attendus. Si les durées des intervalles temporels séparant deux stimulations tactiles deviennent plus longues ou plus courtes, également si les durées des intervalles temporels séparant deux stimulations tactiles sont identiques, d’autres phénomènes (par exemple d’habituation et/ou de dépression) pourraient empêcher l’induction des effets attendus.- the maximum, minimum and average duration of the time interval separating two tactile stimuli (ISI or InterStimulus Intervals in English), this maximum duration is 3.013s, this minimum duration is 0.083s and this average duration is 0.856s. It is advantageous for the time intervals to respect these established durations in order to effectively trigger the expected effects. If the durations of the time intervals separating two tactile stimulations become longer or shorter, also if the durations of the time intervals separating two tactile stimulations are identical, other phenomena (for example habituation and/or depression) could prevent the induction of the expected effects.
  • - la durée de la séquence des stimulations tactiles qui est, par exemple, comprise entre 20 minutes et 180 minutes, par exemple 20 minutes, 60 minutes, 120 minutes ou 180 minutes- the duration of the sequence of tactile stimulations which is, for example, between 20 minutes and 180 minutes, for example 20 minutes, 60 minutes, 120 minutes or 180 minutes
  • - la durée de chaque stimulation tactile qui est par exemple comprise entre 8 et 20 ms. - the duration of each tactile stimulation which is for example between 8 and 20 ms.
  • La loi de poisson est une loi de probabilité discrète qui décrit la survenance d’événements se produisant dans un intervalle de temps fixé. En particulier cette loi de probabilité permet de déterminer les instants de réalisation de ces évènements, la fréquence moyenne entre deux évènements et le temps écoulé entre deux évènements. Cette fréquence et ce temps écoulé sont paramétrés par le paramètre lambda (λ).The Poisson distribution is a discrete probability distribution that describes the occurrence of events occurring within a fixed time interval. In particular, this law of probability makes it possible to determine the instants of occurrence of these events, the average frequency between two events and the time elapsed between two events. This frequency and this elapsed time are parameterized by the parameter lambda (λ).
  • La montre le système 101 de stimulation tactile selon un mode d’utilisation sur le visage.
