Introduction: Rheumatoid Arthritis (RA) may lead to gait deviations 1. Threedimensional
gait analysis includes measurements of movement from multiple joints1.
The complexity of gait data puts high demands on clinicians and researchers
interpreting these data in a global sense. The newly developed Gait Deviation Index
(GDI) 2 measures overall gait deviations and captures functional aspects of walking.
The aim of this study was to describe gait deviations expressed as, GDI-scores, in
patients with RA. Methods: Forty patients with RA (mean 56,6 yrs) and 40 age- and
gender matched healthy controls (mean 56,3 yrs) were examined. 3-D gait analysis
was performed (Oxford Metrics) and GDI-scores were calculated1, 2. Pain during
walking was measured in the patient group with Visual Analog Scale (VAS). Results:
Mean pain during walking was 33 mm in the RA group and mean disease duration
was 13,8 yrs. Mean GDI score was 14 % lower in the RA group (87) compared to
controls (102) (p
