Abstract

The present invention relates to a measurement system for reproducibly measuring a response time profile in complex neurocognitive tasks. The measuring system comprises a measuring body, at least one force source, at least one holding device, at least one triggering unit, at least one first sensor unit for acceleration measurement, at least one second sensor unit, at least one interface for data transmission and at least one data processing unit. The invention also relates to a method for quantifying the reaction time, in which method a measurement system is used. This prevents the human influence during the test from being exerted as much as possible. By shifting the data processing, the measurement system is able to construct an independently growing and anonymous data base that improves accuracy by its continuously growing amount of data. This also enables conclusions to be drawn as to the potentially risky change in reaction time up to the indication and/or recognition of neurodegenerative diseases.

Description

Measurement system for measuring hand-eye reaction capability Technical Field The present invention relates to a measurement system adapted to measure the hand-eye reaction capacity of a human being when performing complex neurocognitive motor tasks. Background The complex neurocognitive motor tasks are primarily affected by the individual's hand-eye reaction ability, attention, and grip function. A minimal example of a test setup for detecting a subject's hand-eye reaction capability, attention, and grip function is the drop bar (Fallstab) test. In the drop bar test, a bar of suitable length (often about 50 cm to 100 cm) is held vertically in the hand by the test leader in the simplest case. The held lever is located above or loosely in the hand of the subject to be measured. The test leader releases the lever. The rod is accelerated by the gravitational force of the earth and is grasped by the subject after a short period of time. The reaction time of the subject can be deduced from the physical law of free fall by the path travelled by the rod. This solution has a number of limitations that may affect the efficiency of the reaction of the subject. The minimum example has low objectivity in the described test setup. Solutions are known from the prior art in order to improve the repeatability of the results of the drop bar test by means of technology. A drop bar test is disclosed in TW 2011022894 A1, in which a stopwatch is integrated. The rod is connected to its holding device before the measurement in such a way that the rod hangs vertically. The holding means are for example electromagnets. The start of the measurement is determined by the test conductor, which opens the holding device-in the case of an electromagnet-via pressing a button-interrupts the power supply. A stopwatch in the interior of the stick is started and the stick is accelerated by the earth's gravitational field. A second switch is present on the outside of the lever. If the stick is grasped, the stopwatch stops and the measured time difference is displayed directly by a display on the stick. A compact device for measuring different types of reaction capacities is shown in US 2010/034443 A1. The device provides an indication to the subject, for example by visual stimulation (by different colored LEDs) or by auditory stimulation-pressing a determined key on the device. Where the time interval required for the subject to perform the procedure is measured. Different response times can be investigated depending on the type and application of the stimulus. In addition to simple reaction times, a decision component or selection component can also be introduced into the exercise task. Additionally, the device has an accelerometer. By means of which accelerometer the acceleration changes are detected and thus a stopwatch is implemented. The device has a simple display via which information of the time difference of each measurement is output. In JP 55-43019 an electromagnetically held drop bar is disclosed, wherein the triggering (starting of the watch) is indicated by a determined stimulus. Then, for example, the subject is left with his eyes closed and an audible signal is selected by the test guide. If the signal is a trigger signal, the response time of the movement task to be performed to the stimulation of pure hearing can be measured with the optical analyzer switched off. In a similar manner, different lamps are mounted on the measurement structure. The lamp is illuminated by the test leader. If the lamp is displayed with a trigger signal, the subject must react and measure the hand-eye reaction time. For the prior art, only measurement systems are known which derive conclusions about the physiology of the reaction time of the subject from only two measured times. None of the mentioned technical solutions enables measurement tasks that exceed the capabilities of a randomly started stopwatch. Disclosure of Invention The object of the invention is to provide a measuring system in which a substantially dense point cloud of measured data is recorded, which records the curve of the force applied by the subject to the measuring system during and shortly after the grasping and the acceleration behavior of the device, and the data thus obtained are processed and compared with limit values and/or with data of a standard database. The object is achieved by a measuring system according to the invention for measuring hand-eye reactions and a method according to the invention for quantifying reaction times in the fields of sports, sports analysis and physical exercise. In this case, the measuring system for measuring the hand-eye reaction capacity in complex neurocognitive motor tasks comprises 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. The first sensor unit configured for acceleration measurement detects an acceleration profile over time. In addition t
