Definitions
- the invention relates to a measuring system which is suitable for measuring the human hand-eye responsiveness when performing a complex neurocognitive movement task.
- test set-up to determine the hand-eye reaction ability, the attention and the gripping function of a test person is the drop stick test.
- a rod of suitable length is held vertically in one hand by an experimenter.
- the held rod is located above or loosely in the hand of a subject to be measured.
- the experimenter lets go of the stick. This accelerates due to the earth's gravity and is caught by the test subject after a short time.
- the distance covered by the rod allows conclusions to be drawn about the reaction time of the test subject from the physical laws of free fall.
- This solution has various limitations that can influence the respondent's reaction performance.
- the minimal example has a slight objectivity in the experimental setup described.
- TW 2011052894 A1 discloses a drop stick test in which a stopwatch is integrated. Before the measurement, the rod is connected to its holding device in such a way that it hangs vertically.
- the holding device is, for example, an electromagnet.
- the start of a measurement is determined by an experimenter who opens the holding device - in the case of the electromagnet, interrupts the power supply by pressing a button.
- the stopwatch inside the rod is started and the rod is accelerated by the earth's gravity field. There is a second switch on the outside of the wand. If the stick is caught, the stopwatch is stopped and the measured time difference is shown directly on a display on the stick.
- US 2010/0324443 A1 shows a compact device for measuring various types of responsiveness.
- the device provides the test person with an optical stimulus, implemented using LEDs of different colors, or an acoustic stimulus Instruction - pressing a specific button on the device.
- the period of time that the test person needs to carry out the action is measured.
- different reaction times can be recorded.
- a decision or selection component can also flow into the movement task.
- the device also has an accelerometer. This detects changes in acceleration and thus realizes a stopwatch.
- the device has a simple display, on which the information of the respectively measured time difference is output.
- JP 55-43019 an electromagnetically held drop bar is disclosed in which the triggering - the starting of the clock - is indicated by certain stimuli.
- the test person's eyes are closed and an acoustic signal is selected by the test director. If this signal is the trigger signal, the reaction time of the movement task to be carried out to a purely acoustic stimulus can be measured with the optical analyzer switched off.
- Various lamps are attached to the measurement setup in an analogous manner. The head of the experiment lights up the lamps. If the lamp is displayed with the trigger signal; this is how the test person has to react and the hand-eye reaction time is measured.
- the object of the invention is to propose a measurement system in which a necessary dense point cloud of measurement data is recorded, which log the course of the force exerted by the test person on the measurement system as well as the acceleration behavior of the instrument during catching and shortly after catching, the processing of the data obtained in this way and to subject it to a comparison with limit values and / or data from a standard database.
- the measuring system for measuring hand-eye responsiveness in a complex neurocognitive movement task comprises at least one measuring body. This experiences an acceleration from its at least one holding device by means of at least one power source.
- a first sensor unit, which is used for Acceleration measurement is formed, the acceleration curve over time.
- a further sensory measured variable is recorded by means of at least a second sensor unit.
- the sensory data obtained in this way can be transmitted as computer-readable signals to a data processing unit by means of at least one data transmission interface.
- the data processing unit processes the transmitted sensory data
- a method for quantifying reaction times and the gripping function is used to create comparable data. This method comprises the following steps: a) Provision of a measuring system for measuring hand-eye responsiveness as well as the gripping function, b) Positioning a test person relative to the measuring system, c) Starting the measurement, d) Randomly triggering the force effect, e) Detecting of the acceleration curve over the duration of the measurement, f) recording of all additional sensory information, g) transmission of all sensory data to the data processing unit, a. Logging of the determined data, b. Saving the determined data, c. Compare the data gained with the existing data set, the normative data and / or, if applicable, disease-specific limit values, d. Analysis of the trend values, h) Output of the evaluation result.
- the measuring body is used to attach and / or hold the sensor units required for the measurement, the trigger unit or its holding points and the interfaces for power and data transmission.
- the force source has an acceleration force on the measuring body.
- the power source is capable of accelerating work on the measuring body.
- the time course of the acceleration work performed is sufficiently known or is measured by a sensor unit. This includes - without being limited to it - the earth's gravitational field in the same way as a technical device for accelerating objects.
- the trigger unit comprises mechanical and / or electromagnetic components that are suitable for initially holding the measuring body against the resistance of the acting power source or for generating a holding effect against the power source.
- the components are to be switched at a freely selectable point in time, with the holding effect coming to a standstill after the switching process. It is useful here to couple the switching process of the triggering unit to a common random generator in order to minimize any subconscious influences as far as possible through pattern formation in the triggering sequences or the influence of a human test supervisor.
- a sensor unit here comprises at least one sensory part, a supplier and a transmission part.
- the sensory part is a technical component that is designed for the qualitative or quantitative detection of at least one physical or chemical property, preferably as a measured variable.
- the physical properties include, for example, the amount of heat, temperature, pressure, sound field sizes, brightness or acceleration, and the chemical properties, for example, the pH value, the ionic strength or the electrochemical potential.
- the component is often designed to record the material properties of its surroundings.
- the supplier provides the energy required to operate the sensor unit. This also includes the energy required to convert the measured variable into electrical signals and to transmit them. This is often provided by an energy source or an energy store, for example a battery, an accumulator or a capacitor.
- the transmission part is that part of a sensor unit which is able to communicate the electrical signals formed in the sensory part. This is done via interfaces that are suitable for signal transmission. These interfaces are not limited to physical interfaces.
- Data processing unit here comprises at least one data processing system which is designed to receive the data determined by the sensor unit and to process it using algorithms. The data processing unit also includes transmitting and receiving devices for this purpose.
- the measured data are compared with the values in a standard database.
- Previous measured values are available in this standard database in the form of raw data and / or refined data. These standard data can contain, for example, previous course curves, disease-specific limit values or digitized literature values of previous methods without being restricted to them.
- the measuring body is a tube or a rod with a preferably round cross-section.
- this tube or rod preferably has a length in the range from 10 cm to 120 cm and / or a diameter in the range from 4 mm to 55 mm and / or a mass in the range from 50 g to 1500 g, with
- foil sensors smaller masses of up to 10 g are also conceivable.
- the conceivable maximum mass is ultimately limited by the physiognomy of the test person and whether he is able to catch the falling massive measuring body without injury, for example 3000 g.
- the source of force for accelerating the measuring body is the earth's gravitational field and the pipe or rod is arranged vertically in the earth's gravitational field.
- the tube or the rod is preferably made of an electrical insulator such as wood or plastic, for example polyethylene, or a light metal, for example aluminum, or a composite material such as glass fiber reinforced aluminum or glass fiber reinforced plastic.
- an electrical insulator such as wood or plastic, for example polyethylene, or a light metal, for example aluminum, or a composite material such as glass fiber reinforced aluminum or glass fiber reinforced plastic.
- the measuring body is made of solid material.
- the required cavities are made in the solid material, preferably wood or plastic, for example polyethylene, or light metal, for example aluminum, using common abrasive machining processes - for example milling and / or drilling.
- This is advantageous in order to be able to achieve a high degree of individuality in the design for a wide variety of end users using current methods.
- a measuring body with a large total mass is used in the field of weight training, since the increased mass also means greater inertia leads to better measurements.
- the test persons show a higher physical strength, which must be taken into account. For example, lighter ones can also be used in this way Measuring body are manufactured, which can be easily caught by frail people.
- the measuring body is produced in a common injection molding process. This is advantageous because it allows large, uniform numbers of items to be manufactured quickly and economically.
- Materials which are suitable for use in 3D printing processes for example PLA or ABS, are particularly preferred. This is advantageous because an individualized production of the measuring system can be realized in this way. This enables structures that cannot be implemented using an erosive process. In this way, the center of gravity of the measuring system can be optimized.
- the various manufacturing processes and embodiments of the measuring body advantageously achieve a broad base of end users.
- the tube or the rod can be sealed in such a way that it can be used in humid environments without the electrical components being able to be damaged. This is advantageous if the test person is measured with sweaty hands through previous physical exercise.
- Another advantage here is that the inductive supply of electrical energy through a plastic cover is significantly simplified compared to a metal cover. Furthermore, the effect on the total mass of the measuring system should not be neglected.
- the measuring body is formed from plastic segments which are arranged to be movable relative to one another and are connected to one another by suitable holding devices. This is advantageous because in this way a small amount of space can be realized in the case of storage. Furthermore, a flexible outer cover minimizes the risk of injury that can result from incorrect use.
- the inductive coupling of the electrical energy in the measuring body is arranged in the holder, in particular in the trigger unit.
- two electromagnets one inside the measuring body and one outside the measuring body, can hold the measuring body in its rest position. If the direction of the current is reversed in one of the electromagnets, there is a force between the electromagnets. The measuring body is accelerated by the electromagnet in it.
- These electromagnets are used to supply energy, as a trigger unit and as a power source.
- the at least second sensor is selected from
- Acceleration sensors which, for example, log the acceleration behavior perpendicular to the primary acceleration axis
- Force sensors suitable for measuring the grip force.
- the force sensors are preferably implemented using piezoresistive pressure sensors, piezoelectric pressure sensors or capacitive pressure sensors.
- the acceleration sensor unit is mounted inside the rod or tube.
- the sensor unit for measuring the grip force is implemented by an area sensor along the surface of the rod. This is advantageous because in this way the construction costs of the entire measuring system and the economic costs are kept small.
- the sensor units are attached to the surface of the tube or rod and are mechanically connected to it.
- a cascade of sensor units is used to record both the grip force and a 2-dimensional image of the force distribution over the surface. This is advantageous because the measured values can be corrected in this way. For example, the gripping reaction may already have taken place - but the full gripping force may only be used with a time delay. Furthermore, the force effects of the individual fingers can be measured.
- At least one sensor unit and at least one data processing unit are telemetrically connected to one another. This enables contactless remote transmission of the data recorded by sensors. This telemetric transmission is advantageous because it allows the algorithms for decentralized data evaluation to run on high-performance data processing systems, for example through the usual IT cloud solutions.
- a local evaluation is conceivable in embodiments of the invention.
- the data is sent by means of a standard transmission - for example WLAN - to a data processing system located within range, evaluated and interpreted on site by the staff present.
- the measuring system is used to carry out measurements of reaction time courses in the area of physical exercise. This is advantageous because competitive athletes in different sports, including martial arts, people in the aerospace sector, rely on precise knowledge of their reaction times to optimize their physical performance in the training process in terms of optimal control of stress intensities, training volumes and the selection of training equipment and content are.
- the measuring system is also used in this area of physical fitness, with the force source for accelerating the measuring body being a force source independent of the earth's gravitational field.
- the measurement system is used in particular in the medical field of application, curative in rehabilitation and preventive in health sports, in order to determine the performance before the training process, to control it during the training process and to quantify it at the end of the treatment duration or the training process.
- the latter advantageously enables the change in the performance status to be assessed as a function of the defined target range in which the performance status should ultimately lie.
- the measuring system is used to check the improvement in hand-eye coordination and gripping function brought about by recreational sports.
- the measuring system is used in the medical field. Especially when measuring the reaction time curves and gripping function on test subjects with neurodegenerative diseases even at an early stage.
- the measuring system is used in the indexing and / or identification of neurodegenerative diseases from the group of synucleinopathies, for example Parkinson's disease, multi-system atrophies, Lewy body dementia or in the indexing neurodegenerative diseases from the group of tauopathies, for example Alzheimer's disease.
- neurodegenerative diseases from the group of synucleinopathies for example Parkinson's disease, multi-system atrophies, Lewy body dementia
- the indexing neurodegenerative diseases from the group of tauopathies for example Alzheimer's disease.
- the advantage of using the measuring system in the fields of medicine for indexing and / or identifying neurodegenerative diseases is the creation of a broad and anonymous database, along with the creation and expansion of at least one norm database. In this way, a potentially huge group is created for the respective illness and, if necessary, the use of network-based data processing systems, for example a cloud solution, also gives the possibility of comparability.
- a non-invasive early indexing and / or identification of neurodegenerative diseases in the context of screening examinations is advantageously made possible by a well-founded data situation in the norm database.
- the measuring body is a rod with a length of 50 cm and the power source is a return spring, which produces an average certification of 10 m / s 2 for the measuring body.
- the return spring is tensioned on a suspension and the rod is locked in a holder.
- a release unit separates the connection between the rod and the holder and releases the spring.
- the rod is accelerated and is caught by the test subject after it has passed the acceleration distance.
- the course of the acceleration measurement is thus initially measured a steep increase in the acceleration. This is followed by a short phase at which the acceleration is ideally zero and the measuring body continues to move in a straight line.
- a negative acceleration acts on the measuring body.
- the measuring body is a rod with a rectangular cross section measuring 4 mm ⁇ 30 mm and a length of 120 mm.
- the sensor units are designed to be flat and are arranged on the surface of the measuring body.
- the power source is the earth's gravity field and the rod is arranged perpendicularly in it.
- the rod is secured against falling on a suspension.
- the sensory recording is started.
- a release unit releases the connection between the rod and the holder and the rod is in free fall.
- the rod is accelerated and is caught by the test subject after it has passed the acceleration distance.
- the trip unit is an electromagnetic trip unit and / or a mechanical trip unit.
- the advantage of a purely electromagnetic trip unit is its simplicity in design and construction. So is for example, by means of electromagnets known per se, analogous to relay technology, the state from holding to releasing can be switched by supplying electrical energy.
- a mechanical release unit is understood to mean both passive systems such as detents, clamps and / or pegs.
- An actively mechanical release unit is understood to mean pressure-operated systems, for example hydraulics or pneumatics.
- the measuring body - the tube or the rod - is connected to a guide system which preferably reduces the degrees of freedom of movement to a translational degree of freedom. This is advantageous because random errors in the measurement are largely avoided.
- the guiding system can also be used to limit the route. This is advantageous as it minimizes the risk of injury if the rod or pipe is not caught.
- method steps a) to c) and / or method steps d) to f) and / or method steps g) b. to g) d. each executed in any order.
- FIG. 1 A perspective sketch of an embodiment is shown in FIG. You can see the stand with holding device, the measuring system designed as a rod and the guide ropes that secure the measuring system against uncontrolled tipping over.
- FIG. 2 shows a sketch with possible dimensions of an exemplary embodiment, the measuring system resting in a height-adjustable stand.
- the minimum height of the height-adjustable stand is entered here - the stand is in the retracted state.
- FIG. 3 shows a sketch with possible dimensions of an exemplary embodiment, the measuring system resting in a height-adjustable stand.
- the maximum height of the height-adjustable stand is entered here - the stand is in the extended state.
- FIG. 4 the measurement of the acceleration profiles of three orthogonal acceleration sensors is shown over a common time axis.
- the diagram at the top of the page shows the acceleration along the x-axis.
- the x-axis assumes the subject's direction of view, which is rigidly straight ahead.
- the middle diagram shows the acceleration over time along the y-axis.
- the y-axis follows the horizon line parallel or anti-parallel.
- the diagram at the bottom of the page shows the acceleration along the z-axis.
- the z-axis which is perpendicular to the x and y axes, points along the radius of the earth.
- the diagram of the z-axis shows a negative course of the acceleration at the point in time 0.95 s. This is the moment at which the release unit accidentally releases the rod. This is followed by a phase of constant acceleration, which lasts from approx. 1 s to 1.15 s. The rod is in free fall. Thereafter, a steep positive deflection of the acceleration can be seen at point in time 1.25 s. Here the test person catches the stick and holds the stick for the following period of time.
- a trembling movement of the rod can be measured immediately after the catch.
- FIG. 5 shows the measurement of the distance and the grip force.
- the time base here corresponds to the same as in FIG. 4.
- the optically measured course of the distance from the top of the rod, the top cap, to the holding device is plotted over time.
- the calculated value of the distance is plotted, which results from the mechanical laws of acceleration.
- the constant increase in the distance after catching the rod at the point in time 1.25 s is not a physical approach between the rod and the holding device, but an artifact of the data analysis.
- the measured grip force is plotted against time in the diagram at the bottom of the page.
- the spontaneous and strong triggering of the sensor causes a brief over-response at the point in time 1. 25 s.After the stick has been safely caught and the information has been processed by the brain, the grip strength - the state of relaxation - begins to decrease.
- a flow diagram of the method and the measuring operation is shown schematically in FIG.
- the entry of personal data such as age, gender, training status or previous illnesses, begins.
- the test is started and completed and the combination of personal data and measurement data is sent to the data processing unit (cloud solution).
- the data is anonymized and compared with existing data sets in the standards database.
- the fully evaluated result is sent to a terminal.
- the user can decide whether the result of the analysis, available as a protocol, should be printed out.
- the resulting data set is entered into the standards database for further use after the process has been completed.
- the measuring system for measuring hand-eye responsiveness comprises the components rod, height-adjustable stand, loading platform and software.
- the rod is divided into the components “top cap” and “body”.
- the body of the drop rod has a round cross-section.
- the rod is made of nylon using 3D printing, as it is transparent to radio waves and does not interfere with the communication units, and has the following external dimensions:
- Two force sensors are attached and mechanically connected to its outer surface. These force sensors are designed as long strips with a length of 610 mm. This gives the length of the force-sensitive surface:
- Length of the measuring range of the force sensor 610 mm
- the body houses a main board for the control tasks inside the rod, a power supply, a WiFi communication unit, the interface for sensors and the processor CPU with firmware.
- the power supply for the rod in order to enable data acquisition, storage and transmission independently of the external energy source of the charging platform, is designed in the form of a Li-ion battery.
- the top cap of the rod is made of the same material as the rod.
- the top cap and has the following external dimensions: Length: 108 mm,
- Width 118 mm
- Three spring contacts are installed on the upper surface of the top cap as an interface for the charging function with the charging platform.
- an optical distance sensor is also integrated into the top cap.
- the acceleration sensors are arranged to measure the three orthogonal spatial directions. At first sight, the acceleration sensors determine the exact time of the catch. The distance between the top edge of the rod and the loading platform is measured by means of the optical distance sensor. There is no need to specify an exact zero line, defined by the lower edge of the hand at the start position.
- the optical distance sensors measure the fall distance between the loading platform and the top cap, and the acceleration sensors record the time of catching, among other things.
- the measuring system is integrated in the height-adjustable stand and enables standardized measurements of patients with a height of 1.50 m to 1.93 m while standing and sitting.
- the measurement while sitting is intended for people whose body size is outside the specified limits and / or for people for whom the measurement while standing is not possible because they are dependent on a wheelchair, for example.
- the individual test position is continuously adjusted, taking into account the height of the elbow.
- a damping layer made of pure ester acoustic foam on the base of the measuring instrument cushions the impact of the stick.
- the loading platform provides the energy for the sensor units of the drop rod.
- three metallic copper contact surfaces are attached to the loading platform at the mechanical interface between the rod and the loading platform. If the rod is in mechanical contact with the loading platform, the rod is adjusted mechanically in such a way that the contact surfaces come into contact with the spring contacts of the top cap and electrical energy can be transmitted. In this way, the Li-Ion battery in the stick is charged.
- two guide wires are attached to the loading platform, which run through the pole and are attached to the catching device of the pole.
- the charging platform has an interface for a power supply unit for power supply.
- a permanent magnet and an electromagnet are installed in the loading platform to hold the rod on the loading platform.
- This electromagnet can be switched or controlled by a WiFi-based communication element. This is how the hold status can be changed. This is implemented on the software side by a random generator. The random dropping of the stick is triggered within 6 s after receiving an orientation signal.
- the software also enables data collection and processing and accesses a standards database that is made available via a cloud.
- the software can be operated from any WLAN-capable device.
- the user interface has several levels. These levels are the input page “input page”, the test interface “testing”, the output page “output page” and the report page “report page”.
- the relevant personal reference variables such as age, gender, training status or previous illnesses, are entered at the level of the “input page”.
- Test parameters for example the sensitivity of the sensor units, can also be set and changed.
- the acceleration to be used can be set and / or adapted.
- the results of the measurements are visually displayed and output on the level of the "output page".
- the data is presented as absolute values and the data is interpreted on the basis of a comparison with the norm database and the age- and disease-specific limit values.
