Reliabilität der statischen Posturografie - Review

Zusammenfassung

Hintergrund: Statische Posturografie ist eine Methode zur Messung von Körperschwankungen. Bislang existieren nur wenige Arbeiten über die Reliabilität ihrer Parameter.

Ziel: Die Literaturarbeit prüfte die Evidenz der Reliabilität dieser Messmethode. Sie soll eine Empfehlung geben, ob die Methode für die physiotherapeutische Forschung geeignet ist.

Methode: Die Datenbankrecherche erfolgte nach Reliabilitätsstudien und Reviews im Zeitraum 1995 - 2006. Die methodologische Qualität und die statistische Berechnung der Reliabilität wurden beurteilt.

Ergebnisse: Keine der 11 die Einschlusskriterien erfüllenden Studien wurde wegen methodologischer Mängel ausgeschlossen. Aufgrund der großen Unterschiede bezüglich Studienpopulation sowie verwendeter Messprotokolle und Parameter war es anhand der ausgewählten Artikel nicht möglich, die Methode generell als reliabel oder nicht reliabel zu identifizieren.

Schlussfolgerung: Da der Nutzen dieser Messmethode unsicher bleibt, sollte jedes Messprotokoll zunächst auf seine Reliabilität hin überprüft werden.

Abstract

Background: Force posturography is used to quantify body sway. However, so far there exist only a limited number of studies assessing the method’s parameters.

Objective: This literature review investigated the evidence of the method’s reliability. Its aim is to give recommendations in view of the method’s applicability in physiotherapy research.

Method: The database research for reliability studies and reviews was carried out for the years 1995 - 2006. The reliability’s methodological quality and statistic evaluation were assessed.

Results: Of the 11 studies meeting the inclusion criteria none was excluded due to insufficient methodological quality. Because of considerable variations in study population, test protocols and calculated parameters of the selected articles it was not possible to identify the method as reliable or not reliable.

Conclusion: As the value of force posturography remains uncertain each test protocol’s reliability should at first be assessed.
