    Method for determining the time required for a timed-up-and-go test
    The invention relates to a method for determining the time required for a person to perform a timed-up-and-go test. Furthermore, the invention relates to a device with which a timed-up-and-go test can be performed.
    A timed-up-and-go test is a test in which a subject sits in a chair. In one possible embodiment, the chair is placed at a predetermined distance of preferably three meters from a wall or other obstacle. Alternatively, the chair may also be placed at such a distance from an obstacle or floor marking to indicate to the subject which positioner he should later turn back to. Finally, there is also the possibility of leaving the position of reversal completely open to the subject.
    The subject is instructed to get up from the chair, to go to the wall, to turn around in the area of the wall, the obstacle, the marking or at a certain distance from the chair, to return to the chair and sit down again on the chair. The time measured to perform this task is recorded. The time the subject needs to complete the task provides insight into the subject's motor skills.
    Both the timed-up-and-go test and various possibilities of mechanical aids for carrying out the timed-up-and-go test are known from the prior art. All methods known in the art employ means which determine the position of the subject with respect to the test arrangement. However, performing the test with automated arrangements is relatively prone to error, so that it is not possible at the moment to achieve an arrangement that is easily buildable and configurable by simple means. The object of the invention is to solve the above-mentioned problems and to provide a method for carrying out a timed-up-and-go test which is simple to perform, and which is almost independent of the available spatial conditions.
    The invention solves this problem with a method for determining the time required for a timed-up-and-go test according to the patent claim 1.
    It is provided that for determining the time required for a timed-up-and-go test and for verifying the determined result, - wherein a distance measuring device is provided, the running of the distance of a person in front of a chair from the backrest of the chair the chair is positioned, in particular by positioning it at a predetermined distance from a wall or obstacle or mark, the distance measurement values (d) recorded by the distance measuring device being continuously recorded, the subject is instructed to get up from the chair, go forward, in particular to the wall, to the obstacle or to the marking, then, in particular in front of the wall or the obstacle or in the area of the mark, to reverse and sit down again on the chair and the subject this Execute instruction according to its possibilities, - whereby it is checked, whether the Test person sitting on the chair and if this is the case for a predetermined period of time, a Zeitnehmung is started and a predetermined start signal is delivered, - wherein the timekeeping is stopped when the subject sits back on the chair, - where from the over the time recorded distance measured values a signal (d (t)) is created, which is examined in particular after the end of the timekeeping, whether it a) continuously increases in a first time range, if necessary also remains unchanged for individual periods except for measurement inaccuracies, and b) continuously decreases again after exceeding a predetermined inversion threshold value (dth, u), optionally remaining unchanged for individual periods except for measurement inaccuracies, until it falls below the lower threshold value (dth, s), and - provided that conditions a) and b ), the test is considered to have been carried out correctly and the time required for this purpose of Ze holding available, if necessary, is displayed.
    With this method it is easily possible to determine whether the timed-up-and-go test has been carried out correctly and to obtain the time required for this simply. In particular, this test can be performed by the subject himself without the assistance of another person.
    A particularly preferred implementation of the test which allows an automatic start provides that the determined distance measurement values are continuously examined before the execution of the test, and in the event that the distance measurement values fall below a lower threshold value for a predetermined period of time, in particular if the test person is seated , the start signal is emitted, which triggers the timekeeping signals to the subject that the test begins.
    In order to carry out a test execution by another person independently of the subject, it can be provided that an external trigger signal causes the delivery of the start signal and the beginning of the timekeeping.
    Alternatively, it may be provided for this purpose that the timekeeping is started when a sensor located in the seat surface of the chair, in particular a pressure sensor, determines the drop in pressure below a predetermined threshold value.
    For the automatic termination of a test, it may be provided that, in the case where the distance measurement values fall short of a lower threshold value after a first and a predetermined period of continuous exceeding of another threshold value for a predetermined period of time, in particular if the test person (1) is back in the chair (FIG. 4), the test is ended and the timekeeping is stopped.
    To end the test by a person may be provided that an external trigger signal terminates the timekeeping, or that the timekeeping is terminated when a located in the seat of the chair sensor, in particular pressure sensor, detects a pressure exceeding threshold.
    A simple verification or falsification of the test results provides that the test is considered incorrect, if the slope of the signal (d (t)) exceeds a predetermined slope threshold and / or if the signal (d (t)) has measured values which correspond to the removal of the chair (5) from the wall (2) or the obstacle, or have readings exceeding the distance of the chair to the marker by a predetermined threshold, and / or - if none of the distance readings (d) of the signal ( d (t)) reaches a predetermined threshold (dth, u) and the subject does not reach the reversal area (32), and / or - if the timekeeping reaches a maximum time without the test being terminated.
    Verifying that the range finder is properly aligned with the wall throughout the measurement provides that the alignment of the range finder with the wall or obstacle is constantly monitored, and changes in alignment of the range finder or threshold deviations in the orientation of the range finder issued from a given, in particular horizontal and / or normal to the wall or obstacle, alignment issued an error message and the measurement result is invalid.
    A simple creation of a recording setting provides that prior to the execution of the test, the distance measuring device is placed on the back of the chair and aligned by the back in the direction of the seated subject out.
    Furthermore, to initialize or create the output arrangement of the measurement setup, it is possible to compare the distance measurement values determined before the start of the test with a predefined threshold value and thus ascertain a correct position of the chair, if the determined distance measurement values lie within a predetermined distance range and / or - if the orientation of the distance measuring device corresponds to a given orientation, in particular horizontal and / or normal to the wall or obstacle.
    For correct positioning of the chair relative to the wall can be preferably provided that the subject is instructed to get up after the test and go behind the chair or leave the receiving area of the rangefinder, and then the correct position and / or orientation of the The chair is again checked according to predetermined criteria and the test is considered incorrect if the position and / or orientation of the chair to the wall does not meet these criteria.
    A preferred distance measurement provides that the distance measuring device determines the distance by means of ultrasonic or laser measurement. By doing so, a further increase in the reliability of the measuring method can be achieved.
    A marking or a wall or an obstacle can be dispensed with in particular if, for the purpose of reversing, a particular acoustic reversal signal is emitted if the distance measuring values of the distance measuring device exceed a predetermined distance, in particular if the test person is in the reversal region.
    A preferred embodiment of the invention will be described in more detail with reference to the following drawing figures.
    In Fig. 1, a simple arrangement for performing a time-up-and-go test is shown. Fig. 2 shows the arrangement shown in Fig. 1 schematically from above.
    To prepare for the test, the test person 1 is placed in a test area (FIG. 1) in which a wall 2 and in front of the wall 2 a substantially level floor area 3 is available. Furthermore, in the area a device comprising a chair 4 with a back 5 is available. On the backrest 5, a distance measuring device 6 is arranged before the execution of the test, which is arranged on the back 5 of the chair 4 and is aligned by the backrest 5 in the direction of a person sitting on the chair 1. In one embodiment, the distance measuring device can be firmly connected to the chair 4 or integrated into the chair 4, in particular in the backrest 5 of the chair. In such a case, the specific orientation of the distance measuring device with respect to the chair 4 can be omitted. Also, the later-mentioned alignment measuring device 7 and control unit 10 may be firmly connected to the chair 4, in particular be integrated in the chair 4 or in the back 5 of the chair 4.
    The chair 4 is thereby aligned so that a subject 1, who sits in a normal posture on the chair 4, sits frontally in front of the wall 2. In the distance measuring device 6 is an ultrasonic or laser rangefinder, which determines the distance of the chair back 5 of the wall 2 in the arrangement shown in Fig. 1.
    Basically, it is not necessary that a massive concrete or wooden wall is present in the test area. Of course, it is also possible that the wall 2 used for the test is a cabinet or a mobile partition or screen. It is only necessary that the distance measuring device 6 identifies the wall 2 when there are no objects or persons other than the subject 1 in the intermediate area between the distance measuring device 6 and the wall 2.
    Instead of a wall 2 also another obstacle can be used, which can be detected by the distance measuring device 6. In principle, however, it is not necessary to use a wall 2 or an obstacle to carry out the test. Rather, it is sufficient if only one mark is visible on the ground, at which the test person is oriented to reverse.
    In well-oriented subjects can even be dispensed with such a mark. Also can then be dispensed with a marker or wall when the subject 1 is given a reverse signal. This can be determined either by an external person accompanying the test or by the distance measurement values determined by the distance measuring device if these exceed a predetermined threshold value.
    If the subject 1 is not in the measuring range of the distance measuring device 6, the distance measuring device 6 indicates its distance from the wall. For this purpose, the distance measuring device 6 is horizontally and normal to the wall 2 aligned. Optionally, an alignment measuring device 7 may be provided, which determines whether the distance measuring device 6 is aligned horizontally.
    In addition, it can be additionally determined whether the distance measuring device 6 is aligned normal to the wall 2 out. The distance measuring device 6 and, if appropriate, the alignment measuring device 7 are connected to a control unit 10, which is connected downstream of the distance measuring device 6 and which receives the individual distance measurement values d of the distance measuring device 6. During the initialization phase, in addition to the correct orientation of the range finder 6, the control unit 10 additionally checks the range readings d, i. the distance of the backrest 5 from the wall 2, and checks whether the distance measurement values d thus determined are within a predetermined distance range, in the present case of about 3.5 meters. If the control unit 10 determines that the distance of the backrest 5 of the chair 4 from the wall 2 relative to the distance range required for the test is too great or too small, this is displayed on a display unit located on the control unit 10.
    However, the invention is not limited to the exemplary dimensions suggested here. So it is easily possible to extend the distance to be traveled by the subject or to increase the reversal area. The latter is advantageous, for example, when the test subject can not walk without aids and the walking aid, for example a walker, requires a larger reversal area, for example of one meter. For subjects who can walk without aids, a reversal area with a length of about 40 to 50 cm can be selected.
    After the initialization of the measuring arrangement, the subject 1 sits down on the chair 4. The measured distance of the subject 1 is continuously measured. If the measured distance measurement values d are below a predetermined start threshold value dth, s-if the subject 1 is sitting on the chair 4, the distance measurement values d are less than 10 cm apart so that the start threshold value can be set to 10 cm - for a predetermined period of time, for example 5 seconds , it is assumed that the subject 1 sits on the chair 4. The control unit 10 emits a start signal which signals to the subject 1 that the test begins. In addition, a timekeeping is triggered or started. Alternatively, there is the possibility that the time-keeping is started by a person accompanying the test, who also signals to the subject 1 that the test starts.
    Even before the test procedure, the subject 1 was instructed to get up from the chair 4, to go to the wall 2, to reverse in a reversal area 32 in front of the wall 2 and to sit down on the chair 4 again. Distance measurement values d are continuously determined during the test procedure and evaluated over time, whereby a signal d (t) is created which indicates the determined distance measurement values d over the time t. The timekeeping is stopped when the subject 1 sits back on the chair 4. This can be done by the distance measured values after first and a predetermined period of continuous exceeding of a reversal threshold d, hu, for example, 3 meters, for a predetermined period of time, a lower threshold value, for example, the start threshold, stops, the timing is stopped. This is the case in particular when the test subject 1 is sitting on the chair 4 again. The test is ended, timing is stopped.
    Alternatively, the test can also be ended by a person monitoring the test, this person sending out a trigger signal that ends the timekeeping. Furthermore, the trigger signal can also be generated by another sensor, for example a pressure sensor integrated in the seat surface of the chair 4, when the determined pressure exceeds a predetermined threshold value.
    Subsequently, the signal d (t) of the distance readings d over time t taken during the performance of the test is analyzed. It is examined whether the generated signal d (t) in a first time range continuously increases, if necessary, remains unchanged for individual periods except for measurement inaccuracies and whether the signal d (t) after exceeding a predetermined inversion threshold, which is slightly less than that Distance of the back 5 of the wall 2, in the timed-up-and-go test is usually 3m, again decreases continuously. In this way it can be determined whether the subject has entered the reversal area 32. After leaving the reversal region 32, the signal d (t) should decrease continuously. Also in this case it can be tolerated that the signal value for individual periods remains unchanged except for measurement inaccuracies, as long as the signal d (t) ultimately falls below the lower threshold, which corresponds to a distance of about 10 cm from the chair back 5. In this case, the test is considered to be done correctly. The time duration of the timekeeping required for this purpose is kept available and possibly displayed. Such measurement inaccuracies are based, on the one hand, on inaccuracies of the measuring device and, on the other hand, on the movements of the test person which are necessarily associated with walking or standing. For example, as a tolerable inaccuracy of measurement, a threshold of 10 to 20 cm can be assumed.
    For further validation or invalidation of the test, individual signal parameters can be examined in detail. If the slope of the signal d (t) exceeds a predetermined gradient threshold value, then it can be assumed that the test person has moved out of the receiving region 60 of the distance measuring device 6, which causes a sudden increase in the distance measurement value 6. In general, the gradient threshold value of the signal d (t) can be set at the highest speed expected by the subject 1, possibly increased by a tolerance range. For the present embodiment, the
    Gradient threshold be set at about 5m / s.
    If distance measurement values d are detected in the signal, which correspond to the distance of the chair 4 or the backrest 5 of the chair 4 from the wall 2, then it can be assumed that the test person 1 is not in the receiving area 60 of the distance measuring device 6, otherwise the Detection of the subject 1 in the receiving area 60 between the distance measuring device 6 and the wall 2 would lead to a lower distance measurement value d. For this reason, a test can be invalidated or rejected as incorrect if the signal d (t)
    Distance measurements d corresponding to the distance of the back 5 of the chair 4 from the wall 2.
    Another criterion for the. Invalidation of a signal d (t) determined in the course of the test procedure consists of examining the signal d (t) for whether the subject 1 has actually entered a zone 32 in the inverted area 32 in front of the wall 2, i. has reached a minimum distance dth, u from the arm rest 5, which is approximately 3m in the exemplary embodiment of the timed-up-and-go test. If the distance measurement values d of the signal d (t) do not reach the reversal region 32 or the minimum distance dth, u, respectively, and the test is terminated beforehand, then the test can be considered incorrect and the result rejected, as it can be assumed that the subject 1 has not reached the wall 2 during the test procedure.
    In addition, the test can be aborted even if the timekeeping reaches a maximum time without the test being terminated. In some cases, falls or mental confusion of the subject may cause them not to return to chair 4.
    In addition, it is also possible to continuously monitor during the entire test procedure whether the orientation of the distance measuring device 6 corresponds to the originally set orientation or whether changes in the orientation of the distance measuring device 6 have led to a falsification of the time-up-and-go test. In the case of changes in the orientation of the distance measuring device 6 or deviations in the alignment of the distance measuring device 6 from a predetermined orientation, in particular horizontal and / or normal to the wall, a fault message is output and the measurement result is invalidated.
    Further review at the end of the test may further improve the validity of the test. For this purpose, the subject 1 is instructed to get up after the test and go behind the chair 4 or to leave the receiving area of the distance measuring device 6. Subsequently, the previously mentioned criteria for assessing the correct position and / or orientation of the chair 4 to the wall 2 or the obstacle are checked again.
    In this context, for example, the orientation of the chair to the wall 2 can be checked again: deviations of the orientation of the distance measuring device 6 of a predetermined, in particular horizontal and / or normal to the wall 2 or obstacle, alignment lead to the invalidation of the measurement result.
    Likewise, the determined distance measurement values can also be compared with a predefined threshold value after the conclusion of the test and, thus, a correct position of the chair can be ascertained if the determined distance measurement value lies within a predetermined distance range. If this is not the case, the test is considered incorrect.
