Zusammenfassung
Der kraniozervikale Flexionstest (CCFT) ist als Assessment der motorischen Kontrolle der HWS bekannt. Während dessen Validität ausreichend bewiesen wurde, existieren nur wenige Publikationen zu seiner Reliabilität.
Das Ziel dieser Studie bestand darin, die Intertester-Reliabilität von 2 unabhängigen und verblindeten Testerinnen und mithilfe einer Pressure Biofeedback Unit (PBU) an asymptomatischen Probanden zu untersuchen. Die Datenanalyse umfasste eine prozentuale Einschätzung der Testerinnenübereinstimmung (gewichteter Kappa) und die Berechnung in der eigentlichen Messeinheit der PBU (mmHg) mittels 95 % Limits of agreement.
Die Resultate ergaben eine moderate bis beachtliche Übereinstimmung. In der eigentlichen Messeinheit bestanden trotz guter mittlerer Differenz zwischen den Testerinnen jedoch große Streuungen in der Datenverteilung, die den Test derzeit eher unzuverlässig erscheinen lassen.
Abstract
The craniocervical flexion test (CCFT) is an assessment for cervical spine motor control. While its validity has been well proven there exist only few publications concerning its reliability.
This study aims to investigate the intertester reliability of 2 independent and blinded testers and by means of a pressure biofeedback unit (PBU) in asymptomatic subjects. Data analysis included percentual evaluation of intertester reliability (weighted kappa) and calculation of the real unit of measurement used by the PBU (mmHg) by 95% limits of agreement.
The results showed a moderate to respectable agreement. However, despite good mean deviation between the testers, the real unit of measurement showed a large statistical spread so that the test seems to be unreliable to date.
