    The invention relates to a device for posturography miteiner measuring platform, which has a footprint for a test person, with a base element on which the Mess¬ platform is tiltably mounted by means of a tilting device, and with an air cushion device, with which a basic element carrying Air cushion is formed.
    Such a posturography exerciser is known, for example, from AT 507 646 Bl. The known balance training device has a loosely resting on a rigid base plate hose ring, which is fixed to the underside of a rigid plate. By injecting compressed air into the space bounded by the hose ring, the plate and the base plate, an overpressure is generated, whereby an air cushion lifting the plate is formed.
    Posturography refers to procedures used for the analysis of posture. In posturography, in particular, body fluctuations are registered at the dormant position in the lot. In the prior art, it is already known to analyze the posture with force plates. Here the position of the projection of the body's center of gravity, the so-called pressure center, can be determined objectively. If the body weight is unevenly distributed on the measuring platform, the center of pressure moves forward or backward, to the left or to the right, depending on the displacement of the total body weight. Such deviations can be graphically displayed on a computer screen. These data can be used for various diagnostic purposes.
    However, extensive theoretical and practical tests have shown that the known systems with force plates were not able to analyze the coordination and equilibrium capabilities of the test persons with the desired precision.
    In contrast, the object of the present invention da¬rin to provide a device for posturography of the kind mentioned angege¬, with which the analysis of posture can be improved with simple design means.
    According to the invention, a damping element with a damping material is arranged between the measuring platform and the base element, with which a tilting movement of the measuring platform is damped.
    The invention is therefore based on the fact that the tilting movements of the measuring platform in the posturography are sustained by the damping material so that a hard impact of the measuring platform in the vertical direction during the test is avoided. The measuring platform is preferably pivotally mounted about a vertical axis through the center of the measuring platform. It has surprisingly been found that the meaningfulness of the measurement data can be substantially improved with the device according to the invention. The reason for this is that the test person's equilibrium in the test program is permanently trained without adjustment to a hard end stop. The arrangement of the damping element therefore contributes significantly to the correct measurement. On the other hand, if the measuring platform were to strike against a rigid plate, correct posturography in one pass would not be possible or the measurement would be erroneous. Advantageously, therefore, the results of posturography can be substantially improved. The inventive posturography device is particularly suitable for developing an individual sensorimotor strength and weakness profile for the subject. In addition, effective fall prevention programs can be created.
    In order to uniformly damp the tilting movement of the measuring platform in all directions, it is favorable if the damping material is arranged circulating around the measuring platform and the base element, in particular running around in an annular manner. The damping device therefore preferably extends with a constant cross-section circumferentially between the measuring platform and the basic element. Preferably, the damping material extends below a radially outer edge region of the measuring platform. In posturography, the measuring platform can be continuously tilted by the test person from the middle position in any direction, whereby the underlying section of the damping material is correspondingly compressed. As a result, the tilting movement of the measuring platform can be damped to the same extent for each tilt angle. Advantageously, such a hard impact of the measuring platform in the vertical direction, i. in the z-direction, can be reliably avoided, whereby the predictive and predictive power of the analysis can be significantly increased.
    In order to dampen or cushion the tilting movements of the measuring platform during posturography, it is expedient for the damping device to abut in a substantially horizontal middle position of the measuring platform on its underside. Thus, the cushioning action occurs immediately when the measuring platform is tilted from the substantially horizontal mid-position.
    To adapt the damping characteristic, it is favorable if the damping material is tapered in cross section in the direction of the measuring plate shape. In order to achieve the desired damping properties, on the one hand the cross-sectional geometry of the damping material and, on the other hand, the damping material itself can be adapted. The stronger the damping material converges towards the measuring platform, the weaker is the damping effect, so that a correspondingly harder damping material is to be provided. Conversely, a softer damping material can be used if the cross-sectional area of the damping material is increased.
    To avoid a hard stop for the pivoting or tilting movement of the measuring platform, it has proven to be advantageous if a foam, in particular of polyurethane, is provided as the damping material. The foam keeps the subject on the measuring platform constantly in motion, allowing for particularly advantageous uninterrupted posturography. The damping material between the Meßplatt¬ form and the base element is designed and arranged such that in the posturography tilt angle of between 5 and 20 degrees, preferably substantially 10 degrees, each based on the horizontal center position of the measuring platform can be achieved. Accordingly, the center axis of the measuring platform to be tilted from its vertical normal position in all directions by a maximum tilt angle of 5 to 20 degrees, in particular substantially 10 degrees. The tilting movement of the measuring platform is damped by the damping material until the maximum tilt angle is reached. Preferably, the maximum tilt angle is essentially 10 degrees.
    In order to achieve a modular construction, it is favorable if the damping element is connected to the base element via a detachable connection, in particular a plug connection, and / or that the measuring platform is connected to the damping element via a further detachable connection, in particular a further plug connection. Advantageously, the individual modules can thus be exchanged simply, in particular without tools. This is particularly favorable for the damping element, in which a different damping material can be selected for different purposes.
    To arrange the damping element with structurally simple means in the position as determined on the base element, it is advantageous if the damping element has at least one centering opening for receiving a corresponding Zentrierele¬mentes the base element. Alternatively, the basic element can have a centering opening in which a corresponding centering element of the damping element can be received.
    In order to carry out the posturography optionally with and without tilting, it is favorable if at least three rocker arm elements are provided between the base element or the damping element and the measuring platform, which block between a release position releasing the tilting movement of the measuring platform and a tilting movement of the measuring platform Locking division are ver-swiveled. Preferably, the Kipphebelelemente are articulated base element mounted. By pivoting in the Sperrstel¬lung the rocker arm elements are brought to the measuring platform in a proposal. Alternatively, the rocker arm elements can also be articulated on the measuring platform. In this way, the posturography device can be used for various applications. By manually pivoting the Kipphebelelemen¬te in the blocking position, the tilting movement of the measuring platform is blocked, so that the posturography on the horizontal Bewwegung, i. the movement in x-y direction, the measuring platform is limited. In order to release the pivotability of the measuring platform, the rocker arm elements are pivoted into the release position.
    In order to reliably hold the rocker arm elements in the blocking pitch, it is advantageous if latching elements are provided on the rocker arm elements for latching in the blocking position. When the rocker arm elements pivot inwardly, the latching connection is established. As latching elements latching lugs are preferably provided which cooperate with corresponding latching receptacles in particular on the measuring platform. As a result, it can be prevented, on the one hand, that the measuring platform is inadvertently displaced between the two operating positions, with or without possibility of tilting. On the other hand, the conversion is made particularly easy for the user.
    In order to detect the weight displacements of the user on the measuring platform precisely, it is advantageous if the measuring platform has a multiplicity of pressure sensors, which are preferably arranged substantially regularly on the contact surface. This can be used to create a load profile. It is particularly favorable if, on the contact area between 4000 and 6600, preferably between 4700 and 5900, in particular approximately 5300 sensors are provided. Such pressure sensors are known per se in the prior art. The signals of the pressure sensors are transmitted to a computing device for evaluation. For posturography, it is favorable if the measuring platform for forming the contact area has a circular sensor foil with the pressure sensors, which is preferably composed of a plurality of sensor foil parts, in particular of four substantially four-tandem sensor foil parts. Derar¬tige sensor films with pressure sensors are known from other application areas per se. For use in the apparatus according to the invention for posturography, however, it has proven to be particularly favorable if the circular sensor foil is composed of four quarter-circle-shaped foils which are arranged next to each other on the contact surface in a substantially gap-free manner.
    For processing the measurement signals, it is advantageous if the pressure sensors of the sensor film parts are connected to signal pickups which are connected to a computer via data transfer lines. Preferably, exactly one signal pickup is provided per sensor film part, which receives the measurement signal of the pressure sensors on the respective sensor film part. The measured data are transferred via suitable data transfer lines to a computing device with which an analysis of the measured data is carried out.
    In order to form the air cushion, it is favorable if the air bubble device has a circumferential sealing element delimiting a pressure chamber. The overpressure space is limited by the sealing element, the base element and a sliding surface for the sealing element. As known per se in the prior art, the overpressure chamber is connected via a line to a compressed air device, with which compressed air can be introduced into the overpressure chamber. As a result, an air cushion is formed on the underside of the base element, with which the horizontal mobility of the measuring platform is effected.
    As a sealing element, a hose ring may be provided. The design of the air cushion device is known, for example, from AT 509 939 A1, to which reference can be made for the sake of simplicity.
    As has already become known from AT 509 939 A1, the basic element can be arranged movably in a frame element in a horizontal plane. With regard to the storage of the basic element on the frame or base element, reference may therefore again be made to AT 509 939 A1.
    In order to avoid a hard stop for movements of the measuring platform in the horizontal plane in posturography, it is favorable if the frame element has a receiving element for a guiding element of the base element, wherein a damping stop is formed between the guiding element and the receiving element. The damping stop has a damping material, for example foam or sponge rubber, with which the stop of the guide element of the base element is damped against the receiving element. Preferably, the Dämpfungs¬ material is provided in an annular manner on the inside of the receiving element. Advantageously, the movements of the measuring platform in all three spatial directions can thus be carried out in a damped manner.
    In practice, it has proved to be problematic in the prior art that the hose ring of the air cushion device is excessively deformed by weight displacements on the measuring platform. For this reason, it is advantageous if a spacer element is provided between the base element and the frame element. The spacer element is designed to keep the distance between the sliding surface of the sealing element of the air cushion device and the base element in posturography substantially constant. Preferably, several Distan¬zelemente are provided radially outside of the sealing element to counteract a vertical deformation of the sealing element at Belastun¬gen to all sides.
    In this embodiment, it is favorable if the spacer element has a resiliently deformable spring element in the vertical direction. The spring elements preferably each have at least one spring clip, which is attached to the underside of the Grundelemen¬tes.
    Moreover, it is favorable if the spacer element has a sliding element for sliding on a sliding surface of the frame element. As a sliding element, in particular a ball element can be provided, which is arranged at the free end of the spring element. Each sliding element is preferably connected to the base element via two spring clips.
    The invention will be explained below with reference to a preferred Ausfüh¬ for example, to which, however, it should not be limited, even further. In the drawing show

    1 shows a device 1 for posturography with which an analysis of the posture of a user can be made. The training device 1 has a measuring platform 2, which is shown in FIG. At the top of the measuring platform 2, a footprint 3 is provided on which the person to be examined stands during posturography.
    1, the training apparatus 1 also has a damping element 4 (see FIG. 3) which has a tilting plate 5 on the upper side and a bearing plate 6 on the underside. The measuring platform 2 is tiltably mounted together with the tilting plate 5 of the damping element 4 by means of a Kippeinrich¬ 7 relative to the bearing plate 6 of the damping element 4. In the embodiment shown, the tilting device 7 has a joint 8, in the embodiment shown a universal joint, between the tilting plate 5 and the bearing plate 6. The universal joint 8 is arranged along a central axis of the measuring platform 2. The measuring platform 2 can tilt in all directions about the central axis by means of the tilting joint 8 during posturography.
    1, the training device 1 also has a base element 9 (see FIG. 4), which is connected to an air cushion device 10 on the underside. With the aid of the air cushion device 10, in posturography, an air cushion supporting the base element 4 can be formed. The air cushion device 10 has an annular circumferential sealing element 10 'in the form of a hose ring or a ring body. The sealing element 10 defines an overpressure space 11 below the base element 4, which is connected to an air pressure device (not shown). Due to the air cushion, the measuring platform 2 can be substantially freely moved in all directions during posturography in the horizontal plane. In addition, the base member 9 is connected to the bottom side with a tubular guide member 12 which is movable within a receiving element 13.Thus, the maximum horizontal mobility of the measuring platform 2 can be limited. The receiving element 13 has on the inner side a damping stop 13 'made of an elastically deformable damping material, for example foam, auf.Damit a hard stop of the guide element 12 would be avoided, which would affect the validity of the collected Bewegungs¬ data. In the embodiment shown, the damping stop 13 'is annular. Moreover, FIG. 1 shows a return element 13 "in the form of an elastic part with which the guide element 12 is returned in the direction of a middle position within the receiving element 13. The elastic ropes have the task of centering the entire inner part, so that always the same Aus¬gangsbild is ensured in the measurement.
    As can be further seen from FIG. 1, the spring and damping element 4 has a damping material 15 between the measuring platform 2 and the base element 9, with which any tilting movements of the measuring platform 2 are damped. Due to the damping material 15, therefore, a pivoting of the measuring platform 2 with respect to its main plane of extension is gently braked.
    In the embodiment shown, the damping material 15 extends annularly underneath the measuring platform 2. In FIG. 4 the measuring platform 2 is shown in a substantially horizontal middle position, from which the measuring platform 2 can be tilted in all directions during posturography. In the middle position shown, the damping material 15 is applied to the underside of the tilting plate 5 and the measuring platform 2, so that the damping effect immediately occurs when tilting from the center position. For the purposes of this disclosure, the directional statements refer to "top", "bottom" and "bottom". etc. to the illustrated operating position of the device 1.
    As can be further seen from FIG. 1, the damping material 15 in the embodiment shown is in cross-section in the direction of the measuring platform 2, i. upwards, rejuvenated trained. In order to adapt the damping characteristic, different cross-sectional geometries of the damping material 15 can be provided. The damping material 15 in the embodiment shown is an open-pore foam which achieves the desired damping, but at the same time the maximum tilt angle of about 10 degrees with respect to the horizontal required for posturography Rest position is guaranteed. In Postu¬rographie the measuring platform can permanently tilt by up to 10 degrees in all directions, the test person is always kept in motion by the Dämp-fung.
    As can be seen from FIG. 1, the device 1 for postographic printing has a modular construction, wherein on the one hand the damping element 4 is connected to the basic element 9 via a tool-less detachable connection 16 and on the other hand the measuring platform 2 is connected to the damping element via a further tool-less detachable connection 17 ment 4 is connected. In the illustrated embodiment, the Dämp¬fungselement 4 can be placed in the intended position on the Grundele¬ment 9. For this purpose, the base element 9 has a central elevation 18 in which a corresponding depression 19 of the damping element 4 fits. In addition, the damping element 4 has a centering recess 20 for receiving a corresponding centering element 21 of the Grundelemen¬tes 9.
    1, at least three rocker elements 22 are provided between the base element 9 and the measuring platform 2, which in the direction of arrow 23 between a release position (not shown) releasing the tilting movement of the measuring platform and a blocking division blocking the tilting movement of the measuring platform 2 (cf. Fig. 1) are pivotable. The rocker arm elements 22 are pivotably mounted in the embodiment shown by means of joints 24 on the base element 9. In each case, latching elements 25 in the form of latching lugs are provided on the tilting lever elements 22, with which latching rocker elements 22 can be latched in the locked position with corresponding latching means 25 'on the measuring platform 2 (see FIG.
    As can also be seen from FIG. 1, the measuring platform 2 for forming the contact surface 3 has a circular sensor loop 26, which is formed with a plurality of pressure sensors. The sensor film 26 is arranged below a cover film with which the sensor film 26 is protected against shearing forces. The pressure sensors are regularly distributed over the footprint 3 in order to precisely detect equilibrium displacements of the subject. In the embodiment shown, the sensor sheet 26 is composed of four substantially quarter-circular sensor sheet parts. The pressure sensors of the individual sensor film parts are each connected to a signal pickup 27, which is connected via data transfer lines 28 and 28 '(see FIG. 4) to a computing device (not shown).
    As is further apparent from FIG. 1, the base element 9 is movably arranged in a horizontally plane in a schematically shown frame element 29 with the receiving element 13. Spacer elements 30 are provided between the base element 9 and the frame element 2 (see also Fig. 4). The spacer elements 30 each have a spring element 31 that can be elastically deformed in the vertical direction, which in the embodiment shown is formed by two bow springs 31 '. The spacer elements 30 each have on the side of the frame element 20 a spherical sliding element 32 for sliding on a sliding surface 33 of the frame element 2 9.
    5 to 7 show a diagnosis and therapy device 34, in which the device 1 according to FIGS. 1 to 4 is used. The diagnosis and therapy device 34 has a frame structure 35 with the frame element 29, in which the receiving element 13für the inner part consisting of the measuring platform 2, the Dämp¬fungselement 4 and the base element 9 is formed. Furthermore, a handrail 36 can be seen, to which the subject can stop. In addition, a screen 37 for displaying information is shown, which is pivotably mounted on a support arm 38.
