    Device for detecting and evaluating tremors
    The invention relates to a device for detecting and evaluating tremor in the hand or arm area of a patient, which is held in use in only one hand of the patient. The invention further relates to a method for detecting and evaluating tremor in the hand or arm area of a patient.
    Tremor is the involuntary, rhythmically repeating contraction of opposing muscle groups. There are different types of tremors that can have different causes. For example, a distinction is made between psychogenic tremors, mostly caused by mental disorders, essential tremors, mostly caused by genetic defects, or Parkinson's tremors, caused by Parkinson's disease. For a human being, however, it is almost impossible to distinguish the individual types of tremor only through human observation. In order to avoid misdiagnoses, an attempt is made to provide objective diagnosis or quantification on the basis of sensory measurements, in which the various types of tremor or their strength can be recorded.
    It is state of the art, among other things, to detect tremor with the aid of a device essentially in the form of a writing instrument, as disclosed in AT 515 976 B1. The device comprises at least one pressure sensor in the grip area, at least one gyroscopic sensor and at least one acceleration sensor and a sensor for measuring the skin resistance. The data recorded with the device can be transferred to a computer via a transmission means, where they can be evaluated.
    However, the computer must be equipped with appropriate software and operated by a specialist with experience in technology and diagnostics to evaluate the data.
    2.31
    The invention has for its object to provide a device for detecting and evaluating tremors with which an efficient, objective diagnosis or quantification is possible.
    The object is achieved by a device according to claim 1 and a method according to claim 12.
    The device according to the invention for detecting and evaluating tremor in the hand or arm area of a patient, which is held in use in only one hand of the patient, comprises a housing which extends in the longitudinal direction and is essentially tubular and one in the longitudinal direction front section, a middle section in the longitudinal direction and a rear section in the longitudinal direction. The housing forms at least one first support point for the third phalanx distalis of at least one finger of the patient's hand in the front section and at least one second support point in the space between the thumb and index finger of the patient's hand in the rear section. The device comprises an acceleration sensor for recording measurement data about the tremor, which is arranged in the housing, an evaluation device for autonomous evaluation of the measurement data and providing evaluation data, which is arranged in the housing, a storage device for storing the measurement data and / or the evaluation data , which is arranged in the housing, a display device for displaying the evaluation data which is arranged on the housing, an activation device for activating at least the acceleration sensor, the evaluation device, the storage device and / or the display device which is arranged on the housing, and a battery for supplying at least the acceleration sensor, the evaluation device, the storage device, the display device and / or the activation device with electrical energy.
    The tubular housing is reminiscent of the shape of a writing instrument, making it intuitive for the patient to grasp.
    For optimal measurement of the tremor, the device is held loosely in a patient's fingers. By supporting the device at the second support point, the device is held at the first support point
    3/31 supports and prevents an unnatural force influence due to the grip force or cramping of the fingers.
    The integrated evaluation device means that no separate evaluation device or other additional external components are required. The patient can therefore easily record measurement data himself, which are processed and evaluated by the evaluation device. A technically and / or medically experienced specialist is therefore not necessary in a first step. For a final diagnosis or therapy decision, a doctor can be supported with the help of the data measured and evaluated by the device.
    The device is expediently designed as a so-called handheld device, which can be operated in one hand.
    The activation device also serves as an orientation aid when aligning the device during measurement. For example, the device should be held regularly during the measurement such that the activation device points upwards. In this way, the device is aligned the same every time it is used, which increases the accuracy of the measurements.
    The acceleration sensor is advantageously arranged in the front section.
    The acceleration sensor is thus arranged in the vicinity of the first support point at which the third phalanx (phalanx distalis) of at least one finger of the patient's hand rests on the device. In this way, the path between the acceleration sensor and the fingers is as short and undamped as possible. The stronger a value that the acceleration sensor can measure, the less external interference, such as the patient's trembling, is significant. The quality of the measurement data of the acceleration sensor can thus be improved.
    By improving the quality of the measurement data of the acceleration sensor, data from further sensors, such as sensors of skin resistance, pressure sensors or gyroscopic sensors, for example, become superfluous. The fewer sensors that need to be present, the more cost-effectively the device can be manufactured.
    4.31
    The activation device is advantageously designed as a push button.
    A push button represents the simplest and best known design of an activation device. Even the average user can use this intuitively. In addition, the haptic feedback of the push button makes the device easier to use.
    The evaluation data advantageously comprise an amplitude of the tremor or a frequency of the tremor or an energy content of the tremor.
    The amplitude of the tremor represents the acceleration of the tremor in g-force, in particular milli-g. For example, the basic tremor of a healthy person is in the range of 3 milli-g, while in the case of a tremor the amplitude is in the range of 20 to 300 milli-g lies. In addition, the frequency of the tremor and the energy content of the tremor are evaluated. Based on the available data, an indication of the type of tremor can be given.
    The device advantageously comprises an interface, expediently a wireless interface, for transmitting the evaluation data.
    The evaluated data are stored on the device. The measurement and evaluation of the tremor expediently take place over a longer period of time, for example several weeks. However, the final diagnosis and type of treatment should be finally determined by a medical professional. Through the interface, the measured and / or evaluated data can be sent to the medical specialist, who can re-evaluate the data, which should lead to an optimal diagnosis and consequently to an optimal treatment.
    The device advantageously comprises a loudspeaker for outputting acoustic signals.
    In order to further improve the usability of the device and, in particular, to make it more intuitive, the device can emit acoustic signals. Acoustic feedback gives the patient confirmation of the correct operation of the device. For example, the loudspeaker emits an acoustic signal when the device is activated and / or deactivated when the
    5.31
    Measurement begins and / or ends and / or when the evaluation of the measured data begins and / or ends.
    In addition, the loudspeaker can output a specific sequence of acoustic signals, for example to signal error codes, such as, for example, a low state of charge of the battery, an error in the measurement or evaluation.
    The housing advantageously has a length between 10 cm and 20 cm, in particular between 14 cm and 17 cm, in the longitudinal direction and expediently a diameter between 10 mm and 40 mm, in particular between 15 mm and 30 mm, the front section expediently between Has 10% and 60% of the length, the middle section has between 10% and 60% of the length and the rear section has between 10% and 60% of the length, furthermore expediently the housing at least in the front section is conical in the longitudinal direction is tapered.
    The dimensions of the housing of the device are optimized according to the application. The length of the housing is at least so long that it is possible with conventional hand sizes to support the third phalanx (phalanx distalis) of at least one finger of the patient's hand at the first support point and the second support point in the space between the thumb and index finger of the hand supports the patient. However, if the length of the housing is too long, the center of gravity of the device shifts away from the first and second support points. This effect has a considerable negative impact on the quality of the measurement due to its leverage effect on the first and second support points. A length of 16 cm has most preferably been found.
    The housing has a diameter that is easy to grasp for a patient's usual finger size. However, patients who use the device often have fine motor limitations. The diameter of the housing is therefore large enough that patients with fine motor impairments can grip the housing safely.
    6/31
    The housing of the device tapers in the front portion in the longitudinal direction. The shape of the housing is reminiscent of the shape of a conventional writing instrument and allows the patient to intuitively perceive how the device is to be held. A diameter of 20 mm has most preferably been found.
    The front, middle and rear sections need not be evenly distributed over the length of the device. Depending on the configuration, each of the sections can have 10% to 60% of the length of the device.
    The device advantageously comprises a circuit board on which the acceleration sensor, the evaluation device, the storage device, the display device, the activation device, the battery, the wireless interface or the loudspeaker are arranged, the circuit board advantageously being held in a form-fitting and / or force-fitting manner in the housing and furthermore expediently the housing has at least one guide rail for receiving the circuit board.
    The arrangement of the acceleration sensor, the evaluation device, the storage device and / or the battery on a circuit board simplifies communication between the individual elements. In order to ensure the best possible measurement by the acceleration sensor, the circuit board is held in the housing in a form-fitting and / or non-positive manner. A particularly preferred method is to provide a guide rail for receiving the board in the housing. After the housing has been manufactured, the board can simply be pushed into the housing via the guide rail. The board is then connected to the guide rail in a positive and / or non-positive manner in order to ensure a secure hold.
    The display device is advantageously arranged in the middle section and expediently the battery in the rear section, the housing advantageously being provided with at least one opening for receiving the display device, the activation device and / or the loudspeaker.
    7.31
    Expediently, the display device, the activation device and / or the loudspeaker can also be arranged directly on the housing and connected to the circuit board inside the device by a connection, in particular a cable connection. In this case, no opening in the housing is necessary for the respective element.
    The display device can expediently also be visible during the measurement process. The middle section of the device is hardly covered by the patient's hand or finger during the measurement process. Arranging the display device in the middle section thus enables the patient to see the data displayed thereon even during the measurement process. Although it is obvious to arrange the activation device and the display device next to one another, the display device can also be arranged offset on the housing, so that when the device is operated during the measurement process, the activation device points upwards to align the device and the display device is offset such that the patient can see them at a straight angle.
    The battery is heavy compared to the other components of the device. It is therefore advantageous to place the battery in the rear section. There, the weight of the battery supports the support of the device at the second support point on the space between the thumb and forefinger of the patient's hand.
    The housing advantageously has a removable cover for inserting the battery, the board advantageously being clamped in the housing by the cover.
    The housing is advantageously made of plastic, in particular polycarbonate.
    Plastic enables the housing to achieve a preferred mix of stability and weight. A preferred weight of the case is 35 grams.
    The method according to the invention for detecting and evaluating tremor in the hand or arm area of a patient with the aid of the above-mentioned device comprises the steps:
    Activating the device by means of the activation device;
    8.31
    Holding the device such that the third phalanx (distal phalanx) of at least one finger of the patient's hand at the at least one first support point formed by the housing and the rear portion of the housing in the space between the thumb and index finger of the patient's hand is supported on the at least one second support point, which forms the housing;
    Measuring measurement data about the tremor by means of the acceleration sensor;
    Evaluating the measurement data and providing evaluation data by means of the evaluation device during a predetermined evaluation period;
    Storing the measurement data or the evaluation data by means of the storage device;
    Displaying the evaluation data by means of the display device for a predetermined display time; and
    Deactivate the device after the display period has expired.
    The procedure is characterized by its intuitive guidance of the patient through the individual process steps. In addition, the method offers a compact, time-efficient way of measuring a patient's tremor and evaluating it independently. For the patient, the complexity of using the device and of the method roughly corresponds to the complexity of using a conventional clinical thermometer.
    The method enables a patient's tremor to be measured and evaluated independently. External components are therefore not necessary.
    In addition, the patient is not forced to move the device during the measurement. There is no drawing of shapes, as is customary in known tremor measurement methods. The patient only has to hold the device relaxed and unloaded in the intended position during the measurement period.
    The measurement data are advantageously filtered by the evaluation device and expediently transformed from the time domain into the frequency domain.
    9.31
    The evaluation device filters out unnecessary or disruptive parts of the measurement data. The remaining relevant data are then evaluated directly or, depending on the evaluation data to be evaluated, first transformed from the time domain into the frequency domain in order to be processed more efficiently.
    The measurement duration is advantageously less than 60 seconds, in particular less than 40 seconds. In practice, a measurement duration of approx. 30 seconds has proven to be particularly suitable. The evaluation time is expediently less than 10 seconds. The display time is preferably at least 20 seconds, in particular more than 45 seconds. However, a display time of approx. 30 seconds has proven to be particularly practical in many cases.
    The entire measurement, evaluation and display process therefore maintains a manageable time frame. The measurement duration and the evaluation duration should be as short as possible, however a certain measurement duration is necessary for a reliable measurement result and the evaluation duration depends on the computing power of the evaluation device and the complexity of the data to be evaluated. The display time can be set according to your preference.
    At least one acoustic signal is expediently emitted by the loudspeaker at the beginning of the measurement period and / or at the beginning of the evaluation period and / or at the start of the display period, expediently at least one further acoustic signal at the end of the measurement period and / or at the end of the evaluation period and / or on End of the display period. Acoustic feedback gives the patient feedback in addition to the display device and represents confirmation of the correct operation of the device.
    An exemplary embodiment is explained in more detail below with reference to the accompanying drawings. It shows:
    Figure 1 is a plan view of the device in the open cross section.

    5a and 5b each show a flow diagram of a measurement / evaluation process of the device.
    1 shows a top view of the device 1 for detecting and evaluating tremor in the open cross section, comprising the housing 10. The device 1 is divided into a front section 11, a central section 12 and a rear section 13. On a circuit board 100, which extends within the front section 11, the middle section 12 and the rear section 13 are an acceleration sensor 20, an evaluation device 30, a storage device 40, a display device 50, an activation device 60 in the form of a push button, a battery 70, a wireless Interface 80 and a speaker 90 arranged. The respective elements are controlled by a control device (not shown). Depending on the application, the evaluation device 30 and the storage device 40 can also be installed in a common chip.
    The acceleration sensor 20 is placed on the circuit board 100 such that it is arranged in the front section 11 of the device 1.
    During the measurement, the acceleration sensor 20 acquires measurement data MD about the tremor, which are evaluated independently by the evaluation device 30. The evaluation device 30 then provides evaluation data AD. The evaluation data AD can then be stored in the memory device 40.
    In the rear section 13 of the device 1, the battery 70 is arranged, which supplies the circuit board 100 and all further elements located thereon with electrical energy.
    The housing 10 has a length L and a diameter d. The length L is 16 cm and the diameter d is 20 mm.
    In the front section 13, the housing 10 tapers conically in the longitudinal direction x.
    11/31
    2 shows a top view of the device 1 in the closed state. A lid 18 for opening and closing the housing 10 is arranged in the rear section 13. As can be seen in FIG. 3, the activation device 60 and the display device 50 are arranged in openings 16, 17 of the housing 10 in the central section 12 and are therefore visible from the outside. In the front section 11, the housing has depressions 19 which are intended to serve as contact surfaces for the fingers of the patient.
    FIG. 3 shows a perspective view of the device 1, the cover 18 having been removed for opening the device 1. The housing 10 has guide rails 14, 15, in which the circuit board 100 is inserted into the housing 10. In order to fasten the circuit board 100 to the housing 10, the circuit board 100 is fastened to the housing 10 in a cohesive manner, for example by gluing, and / or non-positively, for example advantageously by clamping it in by means of the cover 18.
    4 shows the device 1 held in the hand H of a patient during the measurement process. The patient grips the device 1 with the fingers of his hand, so that the device 1 with the front section 11 on the third phalanx (distal phalanx) is supported by at least one finger F of the patient's hand H at the first support point AP1. The device 1 is supported in the rear section 13 at a second support point AP2 in the space between the thumb D and index finger Z of the patient's hand H. This position is called the measuring position.
    5a and 5b each show a flow chart of a measurement / evaluation process of the device 1. In step S1, the push button 60 of the device 1 is actuated. It is then checked in a step S2 whether the charge of the battery 70 is sufficient for a measurement / evaluation process. If the charge of the energy is insufficient, the loudspeaker 90 emits an acoustic signal of type 2 in step S3, an acoustic signal of the type 2 are several consecutive tones from the following tones. The method then goes to step S6 and the device 1 is deactivated.
    If the charge of the battery 70 is sufficient for a measurement / evaluation process, the loudspeaker 90 does not emit an acoustic signal of type 2 and the patient can press the push button 60 in step S4 for at least five seconds, that is to say for a long time,
    12/31 to initiate data transmission, advantageously by means of Bluetooth. As a result, in step S5, evaluation data AD that has not yet been transmitted to the storage device 40 is transmitted to an external data processing device via the wireless interface 80. The method then jumps to step S6 and the device 1 is deactivated.
    If, on the other hand, the push button 60 is not pressed long but only briefly in step S4, the method jumps to step S7. Depending on the configuration, it is also possible in this case for the evaluation data AD to be transmitted in parallel via the wireless interface 80 to an external data processing device. In step S7, a further five seconds are waited so that the patient has preparation time in order to hold the device 1 in the measuring position according to the instructions. The process then continues with step S8.
    In step S8, the speaker 90 outputs an acoustic signal of type 1, which indicates that the measurement is beginning. The acoustic signal of type 1 is characterized by the reproduction of a single tone. The process then continues with step S9.
    In step S9, the acceleration sensor 20 acquires measurement data MD about the tremor. The acquisition of the measurement data MD takes a measurement time T1 of approx. 30 seconds. Within the measuring period T1, the evaluation device 30 begins to evaluate already measured data MD. The process jumps to step S10.
    In step S10 it is checked whether the measurement period T1 has already expired. If the measurement period T1 has not yet expired, the method jumps to step S11.
    In step S11, 100 measurement data MD are filtered by the evaluation device 30 by means of windowing, that is to say windowed. The method then jumps to step S12.
    In step S12, the 100 measurement data MD previously windowed in step S11 are transformed by the evaluation device 30 Fourier. The method then jumps to step S13.
    For each partial result, it is checked in step S13 whether there is a so-called overflow, that is, whether a partial result appears so unrealistic that it is a measurement error that is likely due to incorrect use of FIG
    13/31
    Device 1 was caused. Such a measurement error can occur due to an unrealistically too high or an unrealistically too low partial result. If such an overflow occurs, the method jumps to step S14.
    In step S14, the speaker 90 outputs an acoustic signal of type 2. It is also determined that a measurement error has occurred, the measurement data MD are discarded, and the method jumps to step S6, in which the device 1 is deactivated.
    If no overflow occurs in step S13 and the measurement period T1 has expired in step S10, the method jumps to step S16.
    In step S16, the loudspeaker 90 outputs an acoustic signal of type 1 and the acquisition of measurement data MD by the acceleration sensor 20 is ended. The method then jumps to step S 17.
    In step S17, the evaluation device 30 determines various evaluation data AD for the evaluation period T2, such as the amplitude of the tremor, the frequency of the tremor and / or the energy content or the energy of the tremor. The method then jumps to step S18.
    In step S18 it is checked whether the measurement and evaluation are OK. If an error appears realistic, the method jumps to step S14, an acoustic signal of type 2 is output, the measurement is rejected and the device 1 is deactivated in step S6. If the measurement and evaluation are found to be OK, the method jumps to step S19.
    In step S19, of all evaluation data AD, preferably only a single parameter of the tremor, for example the amplitude, in the unit mg, the frequency or the energy, in the unit mJ, is displayed by means of the display device 50 for a display period T3 of preferably approximately 30 seconds output. The other evaluation data AD are not displayed.
    At the same time, all evaluation data AD are stored in the memory device 40 in step S20. The method then jumps to step S6 and the device 1 is deactivated.
