Description

Technical Field

[0001] This invention relates to a measurement system suitable for measuring human hand-eye reaction ability when performing complex neurocognitive motor tasks. Background Technology

[0002] Complex neurocognitive motor tasks are primarily influenced by an individual's hand-eye reaction ability, attention, and grasping function.

[0003] The smallest example of a test setup used to assess a subject’s hand-eye reaction time, attention, and grasping ability is the Fallstab test.

[0004] In the aforementioned pole drop test, in its simplest form, the test instructor holds a pole of suitable length (often approximately 50 to 100 centimeters) vertically in their hand. Here, the pole is held either above or loosely in the subject's hand to be measured. The test instructor releases the pole. The pole is accelerated by gravity and is caught by the subject shortly afterward. The subject's reaction time can be deduced from the laws of physics of free fall by observing the distance the pole has traveled. This solution has several limitations that may affect the subject's reaction efficiency. The minimal example described has low objectivity in the test setup.

[0005] Several solutions are known from existing technologies to improve the repeatability of drop test results.

[0006] A drop pole test, integrated with a stopwatch, is disclosed in TW 2011052894 A1. The pole is connected to its holding device before measurement, such that the pole is suspended vertically. The holding device is, for example, an electromagnet. The start of the measurement is determined by a test instructor who opens the holding device—by pressing a button to interrupt power in the case of an electromagnet. The stopwatch inside the pole is activated, and the pole is accelerated by the Earth's gravitational field. A second switch is located on the outside of the pole. If the pole is gripped, the stopwatch stops, and the measured time difference is displayed directly on a display on the pole.

[0007] US 2010 / 0324443 A1 discloses a compact device for measuring different types of reaction abilities. The device provides instructions to the subject, for example, through visual stimulation (achieved via LEDs of different colors) or auditory stimulation—by pressing a designated key on the device. The time interval required for the subject to perform the action is measured. Different reaction times can be investigated depending on the type and application of the stimulus. In addition to simple reaction time, decision or selection components can be introduced into the motor task. Additionally, the device includes an accelerometer. Changes in acceleration are detected by this accelerometer, thus functioning as a stopwatch. The device has a simple display that outputs information about the time difference between each measurement.

[0008] JP 55-43019 discloses an electromagnetically held drop bar, wherein a trigger (table activation) is indicated by a defined stimulus. For example, the subject closes their eyes and the test facilitator selects an auditory signal. If the signal is a trigger signal, the reaction time to a purely auditory stimulus for a motor task to be performed can be measured with the optical analyzer off. Similarly, different lights are mounted on the measurement structure. The test facilitator causes the lights to illuminate. If the light indicates a trigger signal, the subject must react, and hand-eye reaction time is measured.

[0009] The existing technology only provides a measurement system that derives physiological conclusions about the subject's reaction time from only two measured moments. None of the mentioned technical solutions can achieve the following measurement task, which exceeds the capabilities of a randomly activated stopwatch. Summary of the Invention

[0010] The object of this invention is to provide a measurement system that records a necessary dense point cloud of measurement data, the point cloud recording curves of the forces applied to the measurement system by the subject during and shortly after grasping, as well as the acceleration behavior of the device; the data thus obtained is processed and compared with threshold values ​​and / or with data from a standard database.

[0011] The objective is achieved by a measurement system for measuring hand-eye reaction according to the invention and a method for quantifying reaction time in the fields of motion, motion analysis and physical exercise according to the invention.

[0012] Here, a measurement system for measuring hand-eye reflexes in complex neurocognitive motor tasks includes at least one measuring body. The measuring body is accelerated from its at least one holding device by means of at least one force source. Here, a first sensor unit configured for acceleration measurement detects an acceleration curve over time. In addition to measuring the acceleration curve, a parameter measured by another sensor is detected by means of at least one second sensor unit.

[0013] The sensor data obtained in this way can be transmitted to the data processing unit as a computer-readable signal via at least one interface for data transmission.

[0014] The data processing unit processes the transmitted sensor data.

[0015] A method for quantifying reaction time and grasping ability to create comparable data. The method includes the following steps:

[0016] a) Provide a measurement system for measuring hand-eye reaction ability and grasping function;

[0017] b) Positioning the subject relative to the measurement system;

[0018] c) Begin measurement;

[0019] d) Randomly triggers the action of force;

[0020] e) Detect the acceleration curve over the measurement duration;

[0021] f) Detect all additional sensor information;

[0022] g) Transmit all sensor data to the data processing unit;

[0023] a. Record the determined data;

[0024] b. Store the determined data;

[0025] c. Compare the obtained data with existing data records, standard data, and / or, where necessary, with disease-specific threshold values;

[0026] d. Analyze the curve values;

[0027] h) Output the evaluation results.

[0028] The terminology used is defined in more detail below.

[0029] Measuring body: The measuring body is used to fix and / or hold the sensor unit, trigger unit, or holding point of the sensor unit and trigger unit required for measurement, as well as the interface for force transmission and data transmission. The force source applies an accelerating force to the measuring body.

[0030] Force source: The force source is capable of performing acceleration work on the measuring body. Here, the time curve of the acceleration work performed is well known or can be detected by sensor unit measurement techniques. This includes—but is not limited to—the Earth's gravitational field, which is the same as that of the technical device used to accelerate the object.

[0031] Triggering Unit: The triggering unit comprises mechanical and / or electromagnetic structural elements adapted to first overcome the resistance of an acting force source to hold the measuring body or to generate a holding action against the force source. Here, the structural elements are switched at a freely selectable time, wherein the holding action ends after the switching process. It is advantageous to couple the switching process of the triggering unit to a general random generator in order to minimize, as far as possible, the potential subconscious influence due to the formation of patterns in the trigger sequence or the influence of the human test facilitator.

[0032] Sensor unit: Here, the sensor unit includes at least one sensor component, a power supply, and a transmission component.

[0033] A sensor component is a technical element configured to qualitatively or quantitatively detect at least one physical or chemical property (preferably as a measurement parameter). Physical properties include, for example, heat, temperature, pressure, acoustic field parameters, brightness, or acceleration, while chemical properties include, for example, pH value, ionic strength, or electrochemical potential. The component is often configured to detect the material properties of the environment in which it is located.

[0034] These parameters are detected using physical or chemical effects and converted into electrical signals.

[0035] The power supply provides the energy required for the operation of the sensor unit. This includes the energy needed to convert measured parameters into electrical signals and to transmit those signals. This is often provided by energy sources or energy storage devices, such as batteries, accumulators, or capacitors.

[0036] The transmission component is a part of the sensor unit capable of transmitting electrical signals generated within the sensor unit. This is accomplished via an interface suitable for signal transmission. These interfaces are not limited to physical interfaces.

[0037] Data processing unit: Here, the data processing unit includes at least one data processing device configured to receive data determined by the sensor unit and process the data using an algorithm. Furthermore, the data processing unit includes transmitting and receiving means for this purpose.

[0038] The measured data are compared with values ​​in a standard database. This standard database contains measurements to date in the form of raw and / or refined data. This standard data may include, but is not limited to, to date trend curves, disease-specific threshold values, or digitized literature values ​​of to date methods.

[0039] In embodiments of the invention, the measuring body is a tube or rod, preferably with a circular cross-section. Preferably, the tube or rod has a length ranging from 10 cm to 120 cm and / or a diameter ranging from 4 mm to 55 mm and / or a mass ranging from 50 g to 1500 g, wherein even smaller masses down to 10 g can be conceived by using a thin-film sensor. The maximum conceivable mass is ultimately limited here by the subject's shape and by whether the subject can catch the falling, heavy measuring body without injury, for example, 3000 g. Here, the force source for accelerating the measuring body is the Earth's gravitational field, and the tube or rod is vertically positioned within the gravitational field.

[0040] Preferably, the tube or rod is constructed of an electrical insulator, such as wood or plastic (e.g., polyethylene), or a light metal (e.g., aluminum) or a composite material (e.g., glass fiber reinforced aluminum or glass fiber reinforced plastic).

[0041] This is advantageous because it allows the telemetry data transmission and / or receiving units to be housed inside the tube or rod without excessively affecting the transmission and / or receiving power of the corresponding device.

[0042] In one embodiment of the invention, the measuring body is made of a solid material. The desired cavity is introduced into the solid material, preferably wood or plastic (e.g., polyethylene) or light metal (e.g., aluminum), using common subtractive machining processes, such as milling and / or drilling. This is advantageous because it allows for the highest degree of personalization in designs for different end users using common processes. Thus, measuring bodies with a large total mass are used, for example, in the field of weight training, because the increased mass and greater inertia also result in better measurements. Additionally, the physical strength of the test subject is also taken into consideration. For example, this also allows for the manufacture of lighter measuring bodies that can be easily gripped by weaker individuals.

[0043] In one embodiment of the invention, the measuring body is manufactured using a commonly used injection molding process. This is advantageous because it also enables the economical and rapid production of uniform, high-volume quantities.

[0044] Particularly preferred materials are those suitable for use in 3D printing processes, such as PLA or ABS. This is advantageous because it allows for the individualized manufacturing of the measurement system. It enables the creation of structures that cannot be achieved through additive manufacturing processes. In this way, the center of gravity of the measurement system can be optimized.

[0045] By utilizing different manufacturing processes and embodying the measurement body, a broad end-user base can be advantageously achieved.

[0046] In one embodiment, the tube or rod can be sealed in such a way that it can be used in a humid environment without potentially damaging the electrical components. This is advantageous when measuring subjects with sweaty hands due to previous physical exercise.

[0047] Another advantage here is that the plastic casing significantly simplifies the inductive power input compared to a metal casing. However, the impact on the overall mass of the measurement system cannot be ignored.

[0048] In one embodiment of the invention, the measuring body is formed of plastic segments movably disposed together and interconnected by suitable retaining devices. This is advantageous because it allows for minimal space requirements during storage. Furthermore, the flexible outer sheath minimizes the risk of injury that could arise from misuse.

[0049] In embodiments of the present invention, an inductive coupling device for transmitting electrical energy to the measuring body is provided in the holding structure, particularly in the triggering unit.

[0050] For example, two electromagnets (one inside the measuring body and one outside) can hold the measuring body in its stationary position. If the direction of the current in one of the electromagnets is reversed, a force is generated between the electromagnets. The measuring body is accelerated by the electromagnet located inside the measuring body. These electromagnets thus act as triggering units and as a force source for power supply.

[0051] In embodiments of the present invention, at least the second sensor is selected from:

[0052] - A distance sensor, preferably an optical distance sensor;

[0053] - An acceleration sensor, which, for example, records acceleration behavior perpendicular to the main acceleration axis;

[0054] - A force sensor suitable for measuring gripping force. Preferably, the force sensor is implemented by means of a piezoresistive pressure sensor, a piezoelectric pressure sensor, or a capacitive pressure sensor.

[0055] This is advantageous because additional data can be detected and evaluated in this way in relation to the subjects' actual reaction time.

[0056] For example, neuromuscular properties, neurological tendencies, and / or muscle-related tendencies can be inferred from the correlation between acceleration curves and grip strength measurements in relation to the motor system.

[0057] In an embodiment of the invention, the acceleration sensor unit is mounted inside the rod or tube. The sensor unit for measuring grip force is implemented by a surface sensor along the surface of the rod. This is advantageous because it keeps the overall construction cost and economic cost of the measurement system low.

[0058] In an embodiment of the invention, the sensor unit is mounted on and mechanically connected to the surface of the tube or rod. Here, a cascade of sensor units is used to record not only the gripping force but also a 2D image of the force distribution on the surface. This is advantageous because corrections to the measurements can be made in this way. Thus, it is possible, for example, that a gripping response has already occurred, but the full gripping force is only used with a time delay. Furthermore, it is therefore possible to measure the force exerted by individual fingers.

[0059] In embodiments of the invention, at least one sensor unit is telemetrically interconnected with at least one data processing unit. This enables contactless, long-distance transmission of sensor-detected data. Such telemetric transmission is advantageous because it allows algorithms for distributed data evaluation to run on high-performance data processing devices, such as cloud solutions prevalent in information technology.

[0060] In embodiments of the invention, local evaluation is conceivable. Here, data is transmitted via standard transmission—such as WLAN—to a data processing device located within the coverage area, the data is evaluated, and the data is interpreted on-site by personnel present.

[0061] In embodiments of the invention, the measurement system is used to measure reaction time curves in the field of physical exercise. This is advantageous because competitive athletes of different sports (including martial artists) and personnel in the aerospace field rely on an accurate understanding of their reaction time curves in order to optimize their physical capabilities during training, in terms of optimizing the control of load intensity, training range, and in selecting training equipment and content.

[0062] In environments that cause muscle atrophy, such as during prolonged stays in outer space, it is necessary to monitor and optimize hand-eye reaction abilities in order to avoid danger in certain situations. The aforementioned measurement system is also used in this field of physical exercise, where the force source used to accelerate the measuring body is a force source independent of Earth's gravitational field.

[0063] In embodiments of the invention, the measurement system is particularly intended for use in medical applications, therapeutically in rehabilitation, and preventively in health and physical exercise, to determine ability before training, control ability during training, and quantify ability at the end of treatment or training. The latter advantageously enables the evaluation of changes in ability status within a defined target range, which should ultimately fall within said target range.

[0064] In an embodiment of the invention, the measurement system is used to examine improvements in hand-eye coordination and grasping function resulting from amateur sports activities.

[0065] When applying measurement systems to a wide range of applications in physical exercise, it is advantageous to create a broad and anonymous data base. This allows for the creation of potentially large control groups and, when necessary, provides the possibility of comparability through the use of network-based data processing devices, such as cloud solutions.

[0066] In embodiments of the present invention, the measurement system is applied in the medical field. It has been used, particularly in the early stages, for measuring reaction time curves and grasping function in subjects with neurodegenerative diseases.

[0067] In particular, the measurement system is used to indicate and / or identify neurodegenerative diseases from the conucleoprotein disease group, such as Parkinson's disease, multiple system atrophy, Lewy body dementia, or the measurement system is used to indicate neurodegenerative diseases from the tau protein disease group, such as Alzheimer's disease.

[0068] When applying measurement systems to medical applications to indicate and / or identify neurodegenerative diseases, it is advantageous to create a broad and anonymized database, including creating and expanding at least one standard database. This creates a potentially large set of data for the relevant diseases and, where necessary, provides the possibility of comparison through the use of network-based data processing devices (e.g., cloud solutions).

[0069] The extensive database, based on standard databases, enables the non-invasive and early indication and / or identification of neurodegenerative diseases within the scope of screening trials.

[0070] In an embodiment of the present invention, the measuring body is a 50-centimeter-long rod, and the force source is a return spring, which causes the measuring body to move at 10 m / s. 2 The average acceleration. Tension the return spring on the suspension and lock the rod to the retaining structure.

[0071] The sensor recording begins. A trigger unit disengages the connection between the rod and the retaining structure, releasing the spring. The rod is accelerated and, after passing through the acceleration path, is grasped by the subject. The acceleration measurement curve thus initially measures a steep rise in acceleration. This is followed by a short phase in which, ideally, the acceleration is zero and the measuring body continues to move linearly and uniformly. Negative acceleration is applied to the measuring body by the subject's grasp.

[0072] In an embodiment of the invention, the measuring body is a rod having a rectangular cross-section of 4 mm × 30 mm and a length of 120 mm. The sensor unit is implemented as a flat surface disposed on the surface of the measuring body. The force source is the Earth's gravitational field, and the rod is vertically positioned within this field. The rod is secured to a suspension device to prevent it from falling. Sensor recording begins. The connection between the rod and the holding structure is disengaged by a trigger unit, and the rod is in free fall. The rod is accelerated and, after passing through an acceleration path, is grasped by the subject.

[0073] In embodiments of the present invention, the triggering unit is an electromagnetic triggering unit and / or a mechanical triggering unit. The advantage of a purely electromagnetic triggering unit is its simplicity in construction and structural form. Thus, for example, by means of an electromagnet (similar to relay technology) known per se, the state can be switched from holding to disengaging by inputting electrical energy.

[0074] Mechanical triggering units are not only understood as passive systems, such as slots, clamps, and / or pins. Active mechanical triggering units are understood as systems that operate under pressure, such as hydraulic or pneumatic systems.

[0075] The advantage of a purely passive mechanical triggering unit is that the triggering unit is independent of external energy sources.

[0076] And the combination—the mechanical method of permanent magnets—is here electromagnetic and / or mechanical.

[0077] In embodiments of the invention, the measuring body—the tube or rod—is connected to a guiding system that preferably reduces the degrees of freedom of motion to translational degrees of freedom. This is advantageous because it minimizes random errors in measurement. Furthermore, the guiding system can be used to implement distance limitation. This is advantageous because it minimizes the risk of injury due to failure to grasp the rod or tube.

[0078] In embodiments of the present invention, method steps a) to c) and / or method steps d) to f) and / or method steps g) b) to g) d) are performed in any order.

[0079] It is also advantageous to combine the above-described embodiments and features in order to realize the present invention. Attached Figure Description

[0080] The invention will now be explained in detail with the aid of some embodiments and the accompanying drawings. These embodiments are intended to describe the invention, but not to limit it.

[0087] Figure 1 The diagram shows a perspective view of one embodiment. Visible are a column with a holding device, a measuring system constructed as a rod, and a guide rope that ensures the measuring system is not tipped over uncontrollably.

[0088] Figure 2 A simplified diagram of a feasible dimensioning method with one embodiment is provided, wherein the measuring system is stationary in a height-adjustable column. The minimum height of the height-adjustable column—when the column is in the inserted state—is given here.

[0089] Figure 3 A simplified diagram of a feasible dimensioning method with one embodiment is provided, wherein the measuring system is stationary in a height-adjustable column. The maximum height of the height-adjustable column—when the column is in its moved-out state—is given here.

[0090] Figure 4The acceleration curves measured by three orthogonal accelerometers are shown on a common time axis. Here, the curve at the upper side shows the acceleration along the x-axis. Here, the x-axis is taken as the subject's strictly straight line of sight.

[0091] The middle curve plots the acceleration over time along the y-axis. Here, the y-axis follows the horizontal line either parallel or antiparallel.

[0092] The curve on the lower side shows the acceleration along the z-axis. The z-axis, perpendicular to the x and y axes, points along the Earth's radius.

[0093] Specifically, a negative acceleration curve can be identified on the z-axis graph at 0.95 seconds. This is the moment the trigger unit randomly releases the lever. This is followed by a phase of constant acceleration lasting approximately 1 to 1.15 seconds. During this phase, the lever is in free fall. A steep positive shift in acceleration can then be identified at 1.25 seconds. Here, the subject grasps the lever and holds it in place for the subsequent time period.

[0094] The jittering motion of the rod immediately following gripping can be measured from the data on the x and y axes.

[0095] exist Figure 5 The supplementary measurement of the acceleration curve shows the measurements of distance and grip strength. Here, the time basis is... Figure 4 Corresponding to the time basis, the curve on the upper side of the recording device is an optically measured curve over time of the distance between the upper side of the rod (the upper side of the top cover) and the holding device. The calculated value of this distance, derived from the mechanical laws of acceleration, is recorded in the middle curve. Here, the continued increase in distance after the rod is gripped at 1.25 seconds is not due to a physical proximity between the rod and the holding device, but rather an artifact in the data analysis.

[0096] The measured grip force over time is recorded in the graph on the lower side. The spontaneous and strong triggering of the sensor results in a short overreaction at 1.25 seconds. After the lever is reliably gripped and the brain processes the information, the grip force begins to decrease—the state of relaxation begins.

[0097] exist Figure 6The flowchart illustrating the method and measurement process is shown schematically. It begins with inputting personnel-related data, such as age, gender, training status, or pre-existing conditions. The test begins and is completed, and the combination of personnel-related data and measurement data is sent to the data processing unit (cloud solution). There, the data is anonymized and compared with existing data records in a standard database. The evaluation results are then sent to the terminal device. The user can decide whether to print the current analysis results as a report. After the process concludes, the generated data records are provided to a standard database for further applications.

[0098] In one embodiment, a measurement system for measuring hand-eye reaction ability includes the following components: a pole, a height-adjustable column, a charging platform, and software.

[0099] The rod is divided into the following components: "top cover" and "body".

[0100] The main body of the pole has a circular cross-section. The pole is manufactured from nylon using 3D printing because nylon is transparent to radio waves and does not interfere with communication units, and the pole has the following external dimensions:

[0101] - Diameter: 30 mm

[0102] - Rod length: 767.1 mm

[0103] - Total weight of the drop bar: 405 grams

[0104] Two force sensors are mounted and mechanically connected to the outer surface of the rod. These force sensors are constructed as strips with a length of 610 mm. This results in the length of the force-sensitive surface:

[0105] - Length of the force sensor's measuring area: 610 mm

[0106] The main body is housed within the rod, comprising a motherboard for control tasks, a power supply, a Wi-Fi communication unit, an interface for sensors, and a CPU with firmware.

[0107] The power supply device of the pole is constructed in the form of a lithium-ion battery so as to enable data detection, storage and transmission of external energy independent of the charging station.

[0108] The upper closing cap (top cover) of the rod is made of the same material as the rod. The top cover has the following external dimensions:

[0109] - Length: 108 mm;

[0110] - Width: 118 mm;

[0111] - Height: 13 mm.

[0112] Three spring contacts are mounted on the upper surface of the top cover as an interface with the charging station for charging. In addition, besides the accelerometer, an optical distance sensor is also integrated into the top cover.

[0113] The accelerometer is configured to measure three orthogonal spatial directions. First, the exact moment of grasping is determined by the accelerometer. The distance between the upper edge of the pole and the charging platform is measured using an optical distance sensor. Here, it is unnecessary to provide an accurate zero-point line, which is defined by the lower edge of the hand at the starting position.

[0114] The optical distance sensor measures the descent path between the charging platform and the top cover, while the accelerometer primarily records the moment of capture. Furthermore, a unit within the top cover is used to open the holding mechanism, thereby triggering free fall.

[0115] A measurement system is integrated into the height-adjustable column, enabling standardized measurements of patients with heights ranging from 1.5 meters to 1.93 meters in both standing and sitting positions. The sitting measurement is configured for individuals whose height falls outside the given limits, and / or for individuals for whom measurements cannot be taken while standing, as they may be wheelchair-dependent. The personalized testing position is steplessly adjustable, taking into account elbow height.

[0116] Additionally, a buffer layer made of polyurethane acoustic foam cushions the impact of the rod on the support legs of the measuring instrument.

[0117] The charging platform provides power to the sensor unit of the drop pole. For this purpose, three copper metal contact surfaces are installed on the charging platform at the mechanical interface between the pole and the platform. When the pole makes mechanical contact with the charging platform, it is mechanically adjusted so that the contact surfaces engage with the spring contacts of the top cover, enabling the transfer of electrical energy. This charges the lithium-ion battery located within the pole. To ensure the pole's orientation relative to the charging platform and to prevent uncontrolled tipping after falling to the ground, two guide wires are installed on the charging platform, extending through the pole and secured to its housing. The charging platform has an interface for power supply. To hold the pole on the charging platform, permanent magnets and electromagnets are installed within it. The electromagnets can be switched or controlled via a Wi-Fi-based communication element, thus changing the holding state. This is implemented in software via a random generator. Here, the random drop of the pole is triggered within 6 seconds of receiving a notification signal.

[0118] - Length (including charging station): 795.3 mm

[0119] The software can also collect and process data and access a standard database provided via the cloud.

[0120] The software can be operated by any WLAN-enabled terminal device. The user interface has multiple layers. These layers are:

[0121] - Enter the page title "Enter Page";

[0122] - Test the interface "test";

[0123] - Output page "Output Page"; and

[0124] - Report page "Report Page".

[0125] In an exemplary testing process, relevant personnel-related reference parameters, such as age, gender, training status, or prior medical conditions, are recorded on the "input page" layer.

[0126] Subsequently, testing and / or trials are initiated via the layer "test". Test parameters, such as the sensitivity of the sensor units, are also adjustable and changeable. Additionally, particularly when using a controllable force source (independent of the Earth's gravitational field), the acceleration to be used can be adjusted and / or matched.

[0127] The measurement results are visually displayed and output on the layer "Output Page". Here, the data are shown as absolute values, and interpreted based on comparisons with standard databases and age-specific and disease-specific threshold values.

[0128] Finally, a "report page" is generated in the form of a PDF file, clearly showing all the results—including interpretations and brief descriptions. Each measurement is stored in the cloud. Multiple measurements are also configured to be compared with only one person, in accordance with data protection protocols.
