Description
Vorrichtung und Verfahren zur Ulcusprophylaxe und zur Früherkennung der Neuropathie beim diabetischen FußDevice and method for ulcer prophylaxis and early detection of neuropathy in the diabetic foot
Beschreibungdescription
Die Erfindung betrifft eine Vorrichtung und ein Verfahren zur Ulcusprophylaxe und zur Früherkennung der Neuropathie beim diabetischen Fuß.The invention relates to a device and a method for ulcer prophylaxis and for the early detection of neuropathy in the diabetic foot.
Es hat sich herausgestellt, daß sich die Druckverteilung während des Stehens eines Diabetikers mit peripherer Neuropathie sich von der einer Normalperson unterscheidet. Die Belastungsverlagerung findet seltener statt.It has been found that the pressure distribution during the standing of a diabetic with peripheral neuropathy differs from that of a normal person. The shift in stress takes place less frequently.
Aus der DE-U-92 03 788 ist eine Schuheinlage zur Ulcusprophylaxe am diabetischen Fuß bekannt, bei der über Drucksensoren bestimmte Belastungswerte erfaßt werden und der Patient über ein Signal aufgefordert wird, die Belastung eines Fußes, d.h. die Stehhaltung zu ändern.From DE-U-92 03 788 a shoe insert for ulcer prophylaxis on the diabetic foot is known, in which certain load values are recorded via pressure sensors and the patient is asked via a signal to indicate the load on a foot, i.e. to change the standing posture.
Da die motorische Störung vor der sensiblen Störung auftritt, weil die Motorik der Nerven im muskulären Bereich eher geschädigt wird, als im sensitiven Bereich, ist es möglich, eine beginnende Neuropathie bereits bei einem Stehtest zu erfassen.Since the motor disorder occurs before the sensitive disorder, because the motor skills of the nerves in the muscular area are more likely to be damaged than in the sensitive area, it is possible to detect the onset of neuropathy in a standing test.

Fig. 3 und Fig. 4 zeigen die unterschiedlichen Ergebnisse bei Probanden ohne und mit eindeutig diagnostizierter Neuropathie. Es handelt sich hier um Ausdrucke von Rohdaten. Die obere Kurve 18, 18' stellt die Belastungswerte des rechten Fußes und die untere Kurve 17, 17' die Belastungswerte des linken Fußes dar. Je größer die Zwischenräume 19, 19' zwischen diesen Kurven sind, desto häufiger und größer ist der Belastungswechsel zwischen beiden Füßen. Es ist gut zu erkennen, wie sehr sich diese Werte bei den beiden Probanden unterscheiden. Während die Versuchsperson ohne eindeutig diagnostizierte Neuropathie in den 15 Meßminuten ständig beim Stehen das Gewicht verlagert, so sind die Druckwerte bei der Versuchsperson mit eindeutig diagnostizierter Neuropathie über die gesamte Zeit bei beiden Füßen fast gleich.
