Abstract

Throughout the rehabilitation process, measuring joint range of motion (ROM) isessential to understand joint kinematics. The universal goniometer (UG) is the mostcommon tool used in the clinical setting for joint ROM measurement. However, areview of the literature examining the reliability of the UG has demonstratedconsiderable variation in results and highlighted the necessity of introducing a morereliable tool.This study aimed to investigate the reliability of a 2-dimensional video analysis system,PnO Clinical Movement DataTM (PnO CMDTM) compared to the UG. Three testersexamined range of motion of eight healthy candidates. Passive sagittal plane motion ofthe hip, knee and ankle joint was measured with and without markers. ICC values>0.60 were considered to be satisfactory.Most intratester ICC values for PnO CMDTM were found to be above the satisfactorylimit (ICC=0.60-0.99). Intratester ICC values for the UG ranged considerably(ICC=0.34-0.94), and some values were below the satisfactory limit. Intertester ICCvalues across all the joints for PnO CMDTM with markers were found to be above thesatisfactory limits (ICC=0.94-0.99).PnO CMDTM was found to be more reliable than the UG. Use of markers was found toincrease the reliability. The present work introduces using advanced technology in jointROM measurement.
