Meßstation zur Erfassung des winkelabhängigen MuskeltonusMeasuring station for recording angle-dependent muscle tone
Die Erfindung betrifft eine Meßstation zur Erfassung des winkelabhängigen Muskeltonus an den Beinen oder Armen eines Menschen, mit zwei durch einen Motor angetriebenen, um 180° gegeneinander versetzten Kurbeln, an deren Enden als Widerlager für die Füße bzw. Hände jeweils ein um eine zur Kurbelachse parallele Achse drehbares Pedal angeordnet ist.The invention relates to a measuring station for recording the angle-dependent muscle tone on the legs or arms of a person, with two cranks driven by a motor and offset by 180° from each other, at the ends of which a pedal is arranged as a support for the feet or hands, which can be rotated about an axis parallel to the crank axis.
Aus der Praxis ist eine derartige Meßstation bekannt, bei der durch die Stromaufnahme eines Elektromotors das zur Kurbelumdrehung benötigte Motordrehmoment bestimmt wird, um den Muskeltonus der Beine zu messen, was insbesondere zur Beurteilung von Spastik, der durch unwillkürliche Tonussteigerungen hervorgerufenen MuskelVerkrampfung, notwendig ist.Such a measuring station is known from practice, in which the motor torque required to rotate the crank is determined by the current consumption of an electric motor in order to measure the muscle tone of the legs, which is particularly necessary for the assessment of spasticity, the muscle cramping caused by involuntary increases in tone.
Da bei der bekannten Meßstation die Stromaufnahme des Elektromotors gemessen wird, ist es nur möglich, den Muskeltonus eines Beinpaars gemeinsam zu betrachten, so daß sich ein integraler Meßwert aus der Überlagerung der Einzelwerte von rechtem und linkem Bein ergibt. Eine differenzierte Betrachtung des Muskeltonus nur eines Beines ist nicht möglich, so daß sich z.B. aus den Meßwerten nicht ablesen läßt, ob ein durch eine Streckspastik verursachter Druck oder ein durch eine Beugespastik verursachter Zug die Änderung des Drehmoments bewirkt. Zur gezielten physiotherapeutischen Behandlung der Spastik durch Bewegungstraining ist es aber wünschenwert, eine objektive Quantifizierung des Muskeltonus zu ermöglichen.Since the current consumption of the electric motor is measured in the known measuring station, it is only possible to look at the muscle tone of one pair of legs together, so that an integral measurement value is obtained by superimposing the individual values of the right and left leg. A differentiated view of the muscle tone of just one leg is not possible, so that it is not possible to tell from the measured values, for example, whether pressure caused by extensor spasticity or tension caused by flexor spasticity causes the change in torque. However, for targeted physiotherapeutic treatment of spasticity through movement training, it is desirable to enable objective quantification of muscle tone.
Die der Erfindung zugrundeliegende Aufgabe besteht daher darin, eine Meßstation der eingangs genannten Art so auszubilden, daß der Muskeltonus jedes Teils eines Gliedmaßenpaars einzeln möglich ist.The object underlying the invention is therefore to design a measuring station of the type mentioned at the beginning in such a way that the muscle tone of each part of a pair of limbs can be measured individually.
Diese Aufgabe wird bei einer Meßstation der eingangs genannten Art dadurch gelöst, daß auf jedem Pedal jeweils ein den durch das Bein oder den Arm der Kurbeldrehung entgegengesetzten Widerstand erfassender Sensor angeordnet ist, und daß ein den momentanen Drehwinkel der Kurbeln bei einer Umdrehung auswertender Winkelmesser vorgesehen ist.This task is solved in a measuring station of the type mentioned above in that a sensor is arranged on each pedal to detect the resistance of the leg or arm to the crank rotation, and that a protractor is provided to evaluate the instantaneous angle of rotation of the cranks during one revolution.
Diese Meßstation beseitigt die bei dem bekannten Stand der Technik gegebenen Nachteile und ermöglicht die differenzierte Messung des Muskeltonus in Abhängigkeit von der Beugung oder Streckung eines bestimmten Armes oder Beines, die nicht von dem um 180° phasenverschobenen Bewegungszustand des anderen Teil überlagert ist.This measuring station eliminates the disadvantages of the known state of the art and enables the differentiated measurement of muscle tone depending on the flexion or extension of a specific arm or leg, which is not superimposed by the movement state of the other part, which is 180° out of phase.
Im Rahmen der Erfindung ist gleichfalls vorgesehen, daß auf jedem Pedal vor und hinter der Achse jeweils ein Sensor angeordnet ist. Dadurch besteht die Möglichkeit, auch noch den Muskeltonus einzelner Muskeln eines Beines oder Armes zu unterscheiden und die Therapie gezielt zu optimieren.The invention also provides for a sensor to be placed on each pedal in front of and behind the axle. This makes it possible to differentiate the muscle tone of individual muscles in a leg or arm and to optimize the therapy in a targeted manner.
Prinzipiell ist es möglich jede Art von Sensor zu verwenden, mit dem die auf das Pedal ausgeübte Kraft gemessen werden kann. Vorteilhaft dabei ist es, wenn jeder Sensor als Druckmeßplatte ausgebildet ist, da diese eine für diesen Zweck geeignete Auflösung hinsichtlich der Zeit und der Kraft bieten und in ausreichend kleinen Abmessungen zur Verfügung stehen, um in das Pedal integriert werden zu können. Im Rahmen der Erfindung ist es gleichfalls möglich, daß jeder Sensor als Dehnmeßstreifen ausgebildet ist.In principle, it is possible to use any type of sensor that can measure the force exerted on the pedal. It is advantageous if each sensor is designed as a pressure measuring plate, since these offer a resolution in terms of time and force that is suitable for this purpose and are available in sufficiently small dimensions to be able to be integrated into the pedal. Within the scope of the invention, it is also possible for each sensor to be designed as a strain gauge.
Um Probleme zu vermeiden, die sich aus der Drehung der 0 Pedale um die Achse und der Umdrehung der Kurbel ergeben, ist es günstig, wenn jedem Pedal ein Sender zugeordnet ist, durch den die von den Sensoren erfaßten Daten mittels Telemetrie zu einem Empfänger übertragbar sind.In order to avoid problems resulting from the rotation of the 0 pedals around the axis and the rotation of the crank, it is advisable if each pedal is assigned a transmitter through which the data recorded by the sensors can be transmitted to a receiver by means of telemetry.
Es ist vorgesehen, daß der Winkelmesser durch einen am Motor angeordneten Impulsgeber gebildet ist, dessen Nullpunkt kalibrierbar ist. Damit ist gewährleistet, daß nicht nur der Verlauf des Muskeltonus während einer Umdrehung der Kurbel verfolgt, sondern daß auch ein bestimmter Tonuswert mit einem bestimmten Beugungsstatus korreliert werden kann.It is intended that the protractor is formed by a pulse generator arranged on the motor, the zero point of which can be calibrated. This ensures that not only the course of the muscle tone is tracked during one revolution of the crank, but that a certain tone value can also be correlated with a certain flexion status.
Insbesondere für die Messung des Tonus von Muskelpartien der Beine ist es vorteilhaft, wenn in variabler Entfernung zu den Kurbeln ein höhenverstellbarer Sitz angeordnet ist, so daß die wesentlichen Elemente eines Heimfahrrades vorhanden sind.Especially for measuring the tone of leg muscles, it is advantageous if a height-adjustable seat is arranged at a variable distance from the cranks, so that the essential elements of a home exercise bike are present.
Für eine optimale physiotherapeutische Betreuung ist es notwendig, weitere Daten zu erfassen, wie Datum, Umgebungstemperatur, Tageszeit, Geburtsdatum des Patienten oder ähnliches und diese bei Auswertung der Meßergebnisse zu berücksichtigen. Daher ist ein Computer zur Speicherung und Auswertung der von den Sensoren und dem Winkelmesser gemessenen Daten sowie personen- und versuchsbezogener Daten und der Steuerung des Versuchs vorgesehen.For optimal physiotherapy care, it is necessary to record additional data, such as date, ambient temperature, time of day, patient's date of birth or similar, and to take these into account when evaluating the measurement results. Therefore, a computer is provided for storing and evaluating the data measured by the sensors and the protractor, as well as personal and test-related data and for controlling the test.
Im folgenden soll die Erfindung an einem in der Zeichnung dargestellten Ausführungsbeispiel näher erläutert werden; es zeigen:In the following, the invention will be explained in more detail using an embodiment shown in the drawing; showing:

Die in der Zeichnung dargestellte Meßstation 1 dient zur Erfassung des winkelabhängigen Muskeltonus der Beine eines Menschen. Die Meßstation 1 weist einen Motor 2 auf, der zwei um 180° gegeneinander versetzte Kurbeln 3,4 antreibt.The measuring station 1 shown in the drawing is used to record the angle-dependent muscle tone of a person’s legs. The measuring station 1 has a motor 2 that drives two cranks 3, 4 that are offset by 180° from each other.
Die Kurbel 3,4 besitzen an ihren Enden als Widerlager für die Füße jeweils ein um eine zur Kurbelachse 5 parallele Achse 6 drehbares Pedal 7,8. Auf jedem dieser Pedale 7,8 ist vor und hinter dessen Achse 6 jeweils ein Sensor 9,9X The cranks 3,4 have at their ends a pedal 7,8 which can be rotated about an axis 6 parallel to the crank axis 5 as a support for the feet. On each of these pedals 7,8 there is a sensor 9,9 X in front of and behind its axis 6.
angeordnet, der den Widerstand mißt, der durch das Bein der Kurbeldrehung entgegengesetzt wird, so daß für jedes Bein getrennt, und dort nach Muskelgruppen unterschieden, der Muskeltonus gemessen werden. Es ist weiterhin ein den momentanen Drehwinkel der Kurbeln 3,4 bei einer Umdrehung auswertender Winkelmesser 10 vorhanden, der die Darstellung des Ergebnis der Messung des Muskeltonus in einem Kraft-Winkel-Diagramm für Ferse und Vorderfuß ermöglicht.which measures the resistance that the leg offers to the crank rotation, so that the muscle tone can be measured separately for each leg and differentiated according to muscle groups. There is also a protractor 10 that evaluates the current angle of rotation of the cranks 3, 4 during one rotation, which enables the result of the muscle tone measurement to be displayed in a force-angle diagram for the heel and forefoot.
Die Sensoren 9 sind gemäß Fig. 1 als Druckmeßplatten ausgebildet und in die Pedale 7,8 integriert. Diese weisen jeweils einen Sender 11 auf, durch den die von den Sensoren 9 erfaßten Daten mittels Telemetrie zu einem Empfänger 12 übertragen werden können, der mit einem Computer 14 in Verbindung steht, in dem weitere für die Messung relevante Daten über den Patienten, den Betreuer und die Versuchsbedingungen gespeichert und ausgewertet werden können. Der Computer 14 dient gleichfalls der Steuerung der Messung, beispielsweise hinsichtlich der Motordrehzahl, Dauer oder Anzahl der Wiederholungen.The sensors 9 are designed as pressure measuring plates according to Fig. 1 and are integrated into the pedals 7, 8. These each have a transmitter 11 through which the data recorded by the sensors 9 can be transmitted by telemetry to a receiver 12, which is connected to a computer 14 in which further data relevant to the measurement about the patient, the caregiver and the test conditions can be stored and evaluated. The computer 14 also serves to control the measurement, for example with regard to the engine speed, duration or number of repetitions.
Am Motor 2 ist der Winkelmesser 10 angeordnet, der als Impulsgeber ausgebildet ist, und bei Fortschreiten der Kurbeldrehung um einen bestimmten Winkelbetrag an die an den Computer 14 angeschlossene Auswerteeinheit einen Impuls sendet. Der Nullpunkt der Kurbelstellung ist kalibrierbar.The angle sensor 10 is arranged on the motor 2 and is designed as a pulse generator. When the crank rotation progresses by a certain angle, it sends a pulse to the evaluation unit connected to the computer 14. The zero point of the crank position can be calibrated.
Die Meßstation 1 weist einen Sitz 13 auf, dessen Höhe einstellbar und dessen Entfernung zu den Kurbeln 3,4 veränderbar ist, so daß die Meßstation 1 an die individuellen Gegebenheiten des Patienten anpaßbar ist.The measuring station 1 has a seat 13, the height of which is adjustable and the distance from the cranks 3, 4 is variable, so that the measuring station 1 can be adapted to the individual circumstances of the patient.
