Zusammenfassung

Die Ganganalyse spielt in der neurologischen und orthopädischen Rehabilitation bei der Beurteilung des Rehabilitationsverlaufes eine wesentliche Rolle. Allerdings sind die bisher zur Verfügung stehenden Messsysteme mit hohem Kosten- und Zeitaufwand verbunden, weshalb ihre Nutzung nur spezialisierten Zentren im stationären Setting vorbehalten ist. Eine vielversprechende Alternative ist das portable Ganganalysesystem RehaWatch. Es ermöglicht durch die Verwendung von Inertialsensoren die Messung der kinemetrischen Größen Beschleunigung und Winkelgeschwindigkeit. Die zugehörige Software analysiert die Sensorsignale und berechnet auf dieser Basis anschließend zeitliche (z. B. Schrittdauer, Gangphasen) und räumliche (z. B. Schrittlänge, Fußwinkel) Parameter. Ziel dieser Untersuchung war es, RehaWatch hinsichtlich seiner Intraobserver-Reliabilität zu testen. An der Untersuchung nahmen 44 gesunde Probanden (Alter: 27,7±4,2 Jahre) teil. Diese absolvierten zu drei Messzeitpunkten (Abstand: 48 h) jeweils drei Versuche (Gehstrecke: 20 m). Es fanden sich varianzanalytisch (Allgemeines Lineares Modell) keine signifikanten Unterschiede in den Gangparametern zwischen den einzelnen Messzeitpunkten. Die Average Measure Intraclass Correlations (ICCs) bewegten sich zwischen 0,691 und 0,959. Neben den Befunden der Varianz- und Korrelationsanalyse deuten auch die Bland Altman Plots auf eine hohe Reliabilität des Messsystems hin.

Abstract

Quantitative gait analysis plays an important role in neurological and orthopedic rehabilitation regarding the evaluation of rehabilitation progress. However, most of the currently available gait analysis systems share the disadvantage of being expensive, time-consuming, and complex. A promising alternative is the portable gait analysis system RehaWatch. It is based on inertial sensors that allow the quantitative measurement of the important kinemetric variables acceleration and angular velocity. The associated software analyzes the sensor signals and calculates temporal (e.g., stride duration, gait phases) and spatial (e.g., stride length, foot angle) parameters on this basis. The aim of this study was to investigate the intraobserver reliability of RehaWatch. A total of 44 healthy subjects (age: 27.7±4.2 years) were included in the study. Each participant underwent three measurements (walking distance: 20 m) for each of the three sessions with a time interval of 48 h in-between. Variance analysis (General Linear Model) revealed no significant differences between gait parameters at different measuring points. ICCs (Average Measure Intraclass Correlations) were between 0.691 and 0.959. In addition to the results of the variance and correlation analysis the Bland-Altman plots suggest high reliability.
