Abstract

The posture monitoring device (10) has an inclinometer (26) delivering a signal representing angle of inclination of the sternum to the vertical. A computer (28) cyclically obtains the angle, compares it to two stored angles for maximum forward and backward inclination of the body, and generates a warning signal if an angle is exceeded. A connector (32) links an external computer (34).

Description

La présente invention concerne un dispositif destiné à être appliqué sur une personne pour détecter et mémoriser certaines postures telles que la flexion et l'extension exagérées du tronc. Ceci permet à cette personne d'améliorer sa conscience gestuelle et ainsi de prévenir une des causes principales des douleurs de dos : les mouvements exagérés vers l'avant et vers l'arrière du tronc lors de la position debout. Le mal de dos est une des pathologies majeures de notre société. Le mode de vie sédentaire entraíne une perte de notre (bon) sens kinesthésique, ce qui ne nous permet plus de sentir précisément les postures physiologiquement permises. Concernant le dos, on estime que 80% de la population présente dans sa vie une défaillance et des douleurs de dos. L'inconfort et les dépenses occasionnés par ces dorsalgies sont préoccupants et nécessitent plus que jamais une politique préventive renforcée de moyens techniques.The present invention relates to a device intended to be applied on a nobody to detect and memorize certain postures such as bending and exaggerated extension of the trunk. This allows this person to improve his gesture awareness and thus prevent one of the main causes of back pain: exaggerated movements towards the front and back of the trunk when standing. Back pain is one of the major pathologies of our society. The sedentary lifestyle leads to a loss of our (good) sense kinesthetic, which no longer allows us to feel precisely the postures physiologically permitted. Regarding the back, it is estimated that 80% of the The population presents in its life a failure and back pains. The discomfort and expense of these backaches is a concern and require more than ever a reinforced preventive policy of means techniques.

Plusieurs solutions ont déjà été décrites pour aider les personnes souffrant du dos à corriger une mauvaise posture.Several solutions have already been described to help people suffering from back to correct a bad posture.

Par exemple, le brevet WO 96/17548 fait référence à un boítier appliqué au niveau des épines vertébrales du porteur. Lorsque ce dernier se penche, la pression exercée par les épines sur les zones d'appui du dispositif permet d'écraser une sorte d'interrupteur et, ainsi, de déclencher une alarme. Les zones concernées sont donc évidemment restreintes et les mouvements de la vie courante déplacent rapidement le boítier, qui n'est alors plus efficace.For example, the patent WO 96/17548 refers to a housing applied to the level of vertebral spines of the wearer. When the latter leans, the pressure exerted by the spines on the bearing areas of the device allows to crush a kind of switch and thus trigger an alarm. The areas concerned are therefore obviously restricted and the movements of life current move the housing quickly, which is then more effective.

Le document WO 90/07360 décrit un appareil dont une face est destinée à être appuyée contre le corps. Une partie de cette face est découpée pour former une plaque de commande. Quand cette plaque est pressée au delà d'un seuil déterminé, elle enclenche un générateur de vibrations constituant un avertisseur tactile. Le réglage du seuil de déclenchement est cependant malaisé et ne correspond pas précisément à des postures déterminées.WO 90/07360 discloses an apparatus of which one side is intended to be leaning against the body. Part of this face is cut to form a control plate. When this plate is pressed beyond a threshold determined, it engages a vibration generator constituting an alarm Touch. However, setting the trigger threshold is difficult and does not correspond precisely to certain postures.

Quant au brevet WO 91/06082, il mentionne une lamelle appuyée en flexion sur le creux lombaire du porteur et reprenant une position de repos lorsqu'une posture incorrecte est adoptée. Elle joue alors le rôle d'un interrupteur et actionne un avertisseur vibro-tactile. Cette méthode souffre cependant d'un inconvénient fondamental : elle restreint la mobilité lombaire, nécessaire à la vie des disque intervertébraux.As for the patent WO 91/06082, it mentions a plate supported bending on the lumbar hollow of the wearer and resuming a rest position when a incorrect posture is adopted. She then plays the role of a switch and operates a vibro-tactile alarm. This method, however, suffers from a fundamental disadvantage: it restricts lumbar mobility, necessary for life intervertebral discs.

La présente invention propose un dispositif peu coûteux, capable de signaler une mauvaise posture du porteur, le seuil de détection pouvant être défini avec précision par un thérapeute. De plus, son installation et son utilisation ne procurent aucune gêne dans les mouvements du quotidien d'un utilisateur normal.The present invention provides an inexpensive device capable of signaling a bad posture of the wearer, the detection threshold can be defined with accuracy by a therapist. Moreover, its installation and use provide no discomfort in a user's daily movements normal.

De façon plus précise, l'invention concerne un dispositif destiné à être appliqué sur une personne pour détecter ses mauvaises postures, c'est-à-dire des postures à risque pathologique, caractérisé en ce qu'il se place sur un segment du corps et comporte :

  • un inclinomètre délivrant un signal représentatif de l'angle d'inclinaison de ce segment par rapport à la verticale,
  • un calculateur recevant ledit signal et programmé pour effectuer cycliquement les opérations :
    • d'obtention d'une mesure de l'angle d'inclinaison,
    • de comparaison de cette mesure à deux valeurs limites mémorisées dudit angle, correspondant respectivement à des position penchées dans une première direction et dans une direction opposée, qui constituent des postures à risque, et
    • de production d'une indication des dépassements des valeurs limites, et
  • des moyens de signalisation, répondant à ladite indication, pour informer la personne et/ou le thérapeute.
More specifically, the invention relates to a device intended to be applied to a person to detect his bad postures, that is to say postures at pathological risk, characterized in that it is placed on a segment of the body and includes:
  • an inclinometer delivering a signal representative of the angle of inclination of this segment relative to the vertical,
  • a computer receiving said signal and programmed to cyclically perform the operations:
    • to obtain a measurement of the angle of inclination,
    • comparing said measurement with two stored limit values of said angle, respectively corresponding to positions tilted in a first direction and in an opposite direction, which constitute risk postures, and
    • production of an indication of exceedances of the limit values, and
  • signaling means, responsive to said indication, for informing the person and / or the therapist.

De façon avantageuse, l'inclinomètre utilisé est un accéléromètre.Advantageously, the inclinometer used is an accelerometer.

En outre, le dispositif comporte une interface permettant, à l'aide de boutons-poussoirs, de mémoriser les deux valeurs limites de l'angle d'inclinaison dans le calculateur.In addition, the device includes an interface allowing, using pushbuttons, to memorize the two limit values of the angle of inclination in the computer.

Selon l'invention, les moyens de signalisation comportent avantageusement, d'une part, une alarme lumineuse et/ou acoustique et/ou vibrante et, d'autre part, une mémoire lisible de l'extérieur comprenant une pluralité de registres affectés à des tranches de temps successives regroupant une pluralité de cycles, le calculateur étant alors programmé pour comptabiliser, dans chacun de ces registres, soit les dépassements des valeurs limites avant et arrière observés à chacun des cycles de la tranche de temps en cours, soit la valeur maximale des dépassements des valeurs limites avant et arrière observés durant cette tranche de temps.According to the invention, the signaling means advantageously comprise, on the one hand, a light and / or acoustic and / or vibrating alarm and, on the other hand, an externally readable memory comprising a plurality of assigned registers at successive time slots grouping a plurality of cycles, the calculator is then programmed to count, in each of these registers, ie exceedances of the forward and backward limit values observed at each cycle of the current time slot, which is the maximum value of the exceedances of the forward and backward limit values observed during this period of time.

Typiquement, lesdits cycles et lesdites tranches de temps ont une durée respective de 100 ms et de 15 minutes.Typically, said cycles and said time slots have a duration respective 100 ms and 15 minutes.

L'invention sera mieux comprise à la lumière de la description qui suit, faite en regard du dessin annexé, sur lequel :

  • la figure 1 est, en a, une vue de profil et, en b, une vue de face d'une personne équipée du dispositif selon l'invention et occupant différentes postures caractéristiques ;
  • la figure 2 est un schéma de principe du dispositif ; et
  • la figure 3 est un schéma logique résumant le principe de fonctionnement du dispositif.
The invention will be better understood in the light of the description which follows, given with reference to the appended drawing, in which:
  • Figure 1 is, a, a side view and at b , a front view of a person equipped with the device according to the invention and occupying different characteristic postures;
  • Figure 2 is a block diagram of the device; and
  • Figure 3 is a logic diagram summarizing the operating principle of the device.

Sur les figures 1a et 1b, on a représenté en 10 le dispositif selon l'invention, installé sur le sternum d'un porteur. Il est maintenu en place par une ceinture thoracique 12 réalisée au moyen d'une bande élastique dont la longueur est ajustable par une boucle.FIGS. 1a and 1b show at 10 the device according to the invention, installed on the sternum of a wearer. It is held in place by a belt thoracic 12 made by means of an elastic band whose length is adjustable by a loop.

On voit, sur la figure 1b, que le boítier du dispositif comporte une interface 14 comprenant :

  • un interrupteur 16 permettant de mettre l'appareil en fonction ou hors-fonction,
  • deux boutons-poussoirs 18 et 20, par l'intermédiaire desquels on peut programmer les seuils de détection d'une mauvaise posture et sélectionner différents modes d'utilisation, et
  • une diode émettrice de lumière (LED) 22, une alarme acoustique (buzzer) 24 et un vibreur 25 qui peuvent avertir le porteur en cas de détection d'une mauvaise posture.
It can be seen in FIG. 1b that the housing of the device comprises an interface 14 comprising:
  • a switch 16 to turn the device on or off,
  • two pushbuttons 18 and 20, through which the detection thresholds of a bad posture can be programmed and different modes of use to be selected, and
  • a light emitting diode (LED) 22, a buzzer 24 and a buzzer 25 which can warn the wearer if a bad posture is detected.

La figure 1a est une vue de profil du porteur dans différentes positions. On appellera α l'angle que fait le dispositif 10, par rapport à la verticale, lorsqu'il est appliqué contre le sternum.Figure 1a is a side view of the wearer in different positions. We will call α the angle made by the device 10, relative to the vertical, when it is applied against the sternum.

Au centre, le porteur se tient droit, talons, fesses, omoplates et tête appuyés contre une verticale, ce qui correspond à une posture de référence pour le tronc. L'angle α a alors la valeur de référence α0.In the center, the wearer stands straight, heels, buttocks, shoulder blades and head against a vertical, which corresponds to a reference posture for the trunk. The angle α then has the reference value α 0 .

Quand le porteur se penche en avant, le thérapeute détermine la limite avant, correspondant à un angle α1, à partir de laquelle des dépassements répétés seraient néfastes dans le temps.When the wearer leans forward, the therapist determines the front limit, corresponding to an angle α 1 , from which repeated overruns would be harmful over time.

De même, lorsque le porteur se penche en arrière, le thérapeute détermine la limite arrière, correspondant à un angle α2, à partir de laquelle des dépassements répétés seraient également néfastes dans le temps. Similarly, when the wearer leans back, the therapist determines the rear limit, corresponding to an angle α 2 , from which repeated overtaking would also be harmful over time.

Comme représenté sur la figure 2, le dispositif 10 comporte essentiellement un inclinomètre 26 fournissant un signal représentatif de l'angle d'inclinaison α, un microprocesseur 28 pour recevoir et traiter ce signal, une mémoire de type EEPROM 30 associée au microprocesseur, l'interface 14, déjà mentionnée, et un connecteur 32 permettant de relier le microprocesseur et la mémoire à un ordinateur 34.As shown in FIG. 2, the device 10 essentially comprises a inclinometer 26 providing a signal representative of the angle of inclination α, a microprocessor 28 for receiving and processing this signal, a memory type EEPROM 30 associated with the microprocessor, the interface 14, already mentioned, and a connector 32 for connecting the microprocessor and the memory to a computer 34.

L'inclinomètre 26 est, en fait, un accéléromètre, tel que celui commercialisé sous la référence ADXL202EB par la firme Analog Device. Il produit une tension proportionnelle au sinus de l'angle d'inclinaison α. Le microprocesseur est, par exemple, le modèle PIC16F873 de Microchip cadencé à 32 kHz.The inclinometer 26 is, in fact, an accelerometer, such as that marketed under the reference ADXL202EB by the firm Analog Device. It produces a voltage proportional to the sine of the angle of inclination α. The microprocessor is, by for example, the model PIC16F873 of Microchip clocked at 32 kHz.

L'utilisation du dispositif selon l'invention implique que son microprocesseur 28 ait enregistré préalablement les angles limites α1 et α2.The use of the device according to the invention implies that its microprocessor 28 has previously recorded the limit angles α 1 and α 2 .

L'opération peut s'effectuer chez un thérapeute qui invite le personne à se pencher en avant ou en arrière jusqu'à atteindre la position que le praticien considère comme limite. A ce moment, il suffit au thérapeute de presser sur les deux boutons 18 et 20 simultanément puis, par exemple, de presser le bouton 18 ou le bouton 20 pour que, respectivement, l'angle α1 ou l'angle α2 soit mémorisé dans le microprocesseur 28. Cette technique étant bien connue de l'homme de métier pour de nombreux domaines d'application, elle ne sera pas décrite ici de manière plus détaillée.The operation can be performed by a therapist who invites the person to lean forward or backward to reach the position that the practitioner considers limit. At this moment, it is sufficient for the therapist to press on the two buttons 18 and 20 simultaneously then, for example, to press the button 18 or the button 20 so that, respectively, the angle α 1 or the angle α 2 is memorized in the microprocessor 28. This technique is well known to those skilled in the art for many fields of application, it will not be described here in more detail.

On va maintenant décrire la suite des opérations effectuées par le microprocesseur 28 lorsque le dispositif 10, ayant en mémoire les angles α1 et α2, est mis en marche sur le sternum de la personne.We will now describe the sequence of operations performed by the microprocessor 28 when the device 10, having in memory the angles α 1 and α 2 , is turned on the sternum of the person.

Le microprocesseur 28 est programmé pour observer le comportement du porteur par tranches de 15 minutes et, à l'intérieur de chaque tranche, effectuer cycliquement les opérations représentées sur la figure 3. Typiquement, la période des cycles est de 100 ms. The microprocessor 28 is programmed to observe the behavior of the carrier in 15-minute increments and, within each bracket, perform cyclically the operations shown in Figure 3. Typically, the cycle period is 100 ms.

La première opération 36 est la mesure de l'angle α à partir du signal délivré par l'inclinomètre 26.The first operation 36 is the measurement of the angle α from the signal delivered by the inclinometer 26.

Puis, le système détermine, en 38, si α est inférieur à α1 ou supérieur à α2.Then, the system determines, at 38, if α is less than α 1 or greater than α 2 .

Si ce n'est pas le cas, cela signifie que le porteur n'a dépassé aucune des limites fixées. L'opération suivante est, alors, en 40, la mise hors fonction des avertisseurs 22 et/ou 24 et/ou 25 qui, s'ils se trouvent enclenchés depuis le cycle précédent, cessent leur action. Le cycle se termine donc.If this is not the case, this means that the bearer has not exceeded any of the limits fixed. The next operation is, then, in 40, the deactivation of the horns 22 and / or 24 and / or 25 which, if they are engaged since the cycle previous, stop their action. The cycle ends so.

Lorsque, au contraire, le système a détecté que α est inférieur à α1 ou supérieur à α2, cela signifie que le porteur a dépassé la limite avant ou la limite arrière. L'opération suivante est, alors, en 42, la vérification que le dépassement a déjà été comptabilisé.When, on the contrary, the system has detected that α is less than α 1 or greater than α 2 , this means that the wearer has exceeded the front limit or the rear limit. The next operation is, then, at 42, the verification that the overshoot has already been counted.

Si ce n'est pas le cas, cela signifie que le dépassement vient juste de se produire. Le système incrémente donc d'une unité, en 44, le registre de la mémoire 30 affecté, pour la tranche de 15 minutes en cours, à la comptabilisation, selon le cas, des dépassements de la limite avant ou de la limite arrière. L'opération suivante est, alors, en 46, l'enclenchement des avertisseurs 22 et/ou 24 et/ou 25 qui signalent au porteur une erreur de posture. Le cycle se termine donc.If this is not the case, it means that the overrun has just produce. The system therefore increments by one unit, at 44, the register of the assigned memory, for the current 15 minute slot, to the counting, as the case may be, of overruns of the forward limit or the rear limit. The next operation is, then, in 46, the engagement of the horns 22 and / or 24 and / or 25 which signal to the wearer a posture error. The cycle ends so.

Lorsque, au contraire, il a été constaté, en 42, que le dépassement détecté a déjà été comptabilisé, cela signifie que le porteur occupe toujours, depuis le cycle précédent, au moins, une position dépassant les limites fixées et que les avertisseurs sont toujours en action. Dans ce cas, le système vérifie, en 48, si le dépassement dure depuis plus de cinq secondes.Where, on the contrary, it has been found, at 42, that the detected overrun has has already been accounted for, this means that the holder still preceding cycle, at least one position exceeding the established limits and that the horns are still in action. In this case, the system checks, at 48, whether the overtaking has been going on for more than five seconds.

Si c'est le cas, cela signifie que le porteur est dans une posture stable (car, par exemple, il lace ses chaussures,.....) et qu'il est donc inutile de l'importuner davantage en laissant les avertisseurs en action. Le système met alors, en 50, les avertisseurs hors fonction et le cycle se termine. If this is the case, it means that the wearer is in a stable posture (because, by example, he is wearing his shoes, .....) and it is therefore unnecessary to bother him more by leaving the horns in action. The system then puts, in 50, the alarms off and the cycle ends.

En variante, on peut prévoir que, dans un tel cas, les avertisseurs ne soient pas arrêtés mais qu'au contraire, les signaux émis aillent en s'amplifiant.Alternatively, it can be provided that, in such a case, the alarms are not stopped but that, on the contrary, the emitted signals go on increasing.

Lorsqu'en revanche, il est remarqué que le dépassement dure depuis moins de cinq secondes, cela signifie qu'il est utile de laisser les avertisseurs en action constante. Le cycle se termine donc, sans les mettre hors fonction.When, on the other hand, it is noticed that the overtaking has lasted less five seconds, it means that it is useful to let the alarms in action constant. The cycle ends, without turning them off.

Le dispositif selon l'invention, tel qu'il vient d'être décrit, peut rester plusieurs jours (sauf la nuit où l'appareil est mis en pause) sur la personne et enregistrer ainsi, toutes les 15 minutes, le nombre de dépassements, en avant ou en arrière, des limites de posture fixées par le thérapeute.The device according to the invention, as just described, can remain several days (except the night the device is paused) on the person and save thus, every 15 minutes, the number of overtaking, forwards or backwards, posture limits set by the therapist.

Lorsque la personne remet le dispositif au thérapeute, celui-ci le connecte à l'ordinateur 34 qui peut fournir, sous forme de tableau ou de graphique, le nombre de dépassements de seuil, vers l'avant et vers l'arrière, intervenus par tranches de 15 minutes tout au long de la période d'observation, avec, en plus, les pauses. Cet histogramme est très utile pour préciser l'étiologie de l'affection et enseigner quelles mesures de prévention sont à envisager.When the person hands over the device to the therapist, the therapist connects him to computer 34 which can provide, in tabular or graphical form, the number of thresholds, both forwards and backwards, 15-minute increments throughout the observation period, with, in addition, the breaks. This histogram is very useful for clarifying the etiology of the condition and teach what preventive measures to consider.

En variante, le système pourrait fournir la valeur maximale des dépassements des valeurs limites avant et arrière, pour chaque tranche de temps de référence.Alternatively, the system could provide the maximum value of the overruns forward and backward limit values for each reference time slot.

Selon une autre variante, il est possible de programmer le microprocesseur de manière à ce que le porteur soit averti lorsqu'il s'approche, typiquement, à moins de quatre degrés, des limites avant et arrière. Dans ce cas, les avertisseurs émettent un signal différent (par exemple, plus faible) de celui émis en cas de dépassement.According to another variant, it is possible to program the microprocessor of in such a way that the wearer is warned when he approaches, typically, unless four degrees, front and rear limits. In this case, the alarms emit a different (for example, weaker) signal from the one emitted in case of exceeded.

On notera, aussi, qu'il est utile, pour le porteur et le thérapeute, de pouvoir désactiver les avertisseurs tout en conservant actif le système d'enregistrement. Cela peut être effectué par une pression prolongée sur le bouton 16 qui les désactive, et par une pression prolongée sur l'autre bouton 18 qui les réactive. It should also be noted that it is useful for the wearer and the therapist to be able to disable the alarms while keeping the recording system active. This can be done by pressing and holding the button 16 which deactivates, and by a prolonged pressure on the other button 18 which reactivates them.

Cette description a été donnée à titre non limitatif et le dispositif peut aussi être installé sur d'autres parties du corps, par exemple un bras ou une jambe, dans certaines conditions thérapeutiques particulières. De manière évidente, l'invention peut être adaptée pour surveiller l'inclinaison du patient, lorsqu'il se penche d'un côté ou de l'autre. Avantageusement, deux inclinomètres peuvent être combinés pour avertir le patient en cas de dépassement de positions limites définies dans les quatre directions.This description has been given in a non-limiting way and the device can also be installed on other parts of the body, for example an arm or a leg, in certain special therapeutic conditions. Obviously, the invention can be adapted to monitor the inclination of the patient, when leaning to one side or the other. Advantageously, two inclinometers can be combined to warn the patient if limit positions are exceeded defined in the four directions.

Enfin, l'histogramme témoignera de l'utilisation effective de l'appareil par le porteur. En effet, dans une variante, on pourra envisager que la mémoire, d'une taille plus importante, puisse enregistrer non plus le nombre de dépassements, mais toutes les valeurs d'angle à une fréquence déterminée, ce qui permettra de détecter que l'appareil a été déposé sans que la pause ait été activée.Finally, the histogram will show the actual use of the device by the carrier. Indeed, in a variant, we can consider that the memory, a larger size, can not record the number of overruns, but all angle values at a specific frequency, which will allow detect that the device has been dropped without pausing.

Claims (10)

  1. Device to be applied to a person in order to detect the incorrect postures thereof, i.e. at-risk postures, said device being placed on a segment of the body, characterized in that it includes:
    an inclinometer (26) delivering a signal representative of the angle of inclination of said segment with respect to a vertical line,
    a calculator (28) receiving said signal and programmed to execute cyclically the operations of:
    obtaining a measurement of the angle of inclination (36),
    comparing this measurement to two stored threshold values of said angle, respectively corresponding to leaning positions in a first direction and a second opposite direction, which constitute at-risk postures (38), and
    generating an indication of breaches of the threshold values (46), and
    indicating means, responding to said indication, to inform the person and/or the therapist.
  2. Device according to claim 1, characterized in that said inclinometer (26) is an accelerometer.
  3. Device according to claim 1, characterized in that it further includes an interface (14) for storing, using push-buttons (18, 20), the two threshold values of the angle of inclination in the calculator (28).
  4. Device according to claim 1, characterized in that said indicating means including a light alarm (22).
  5. Device according to claims 1 and 4, characterized in that said indicating means include an acoustic alarm (24).
  6. Device according to any of claims 1, 4 and 5, characterized in that said indicating means include a vibrating alarm (25).
  7. Device according to any of claims 1, 4, 5 and 6, characterized in that said indicating means include a memory (30) that can be read from the exterior, including a plurality of registers assigned to successive time slots regrouping a plurality of cycles, and in that said calculator (28) is programmed to store, in each of said registers, breaches of the forward and backward threshold values observed at each of the cycles of the current time slot.
  8. Device according to any of claims 1, 4, 5 and 6, characterized in that said indicating means include a memory (30) that can be read from the exterior, including a plurality of registers assigned to successive time slots regrouping a plurality of cycles, and in that said calculator (28) is programmed to record, in each of said registers, the maximum value of breaches of the forward and backward threshold values observed during the current time slot.
  9. Device according to claims 7 and 8, characterized in that said cycles and said time slots have a respective duration of 100 ms and 15 minutes.
  10. Device according to any of claims 1 to 9, characterized in that said positions are forward or backward leaning positions.
