dc.description.abstractThis study aimed to evaluate hip joint kinematic variability and segment coordination variability during walking according to pain and radiographic disease severity in people with hip osteoarthritis. Fifty-five participants with hip osteoarthritis had pain severity assessed during walking using an item on the Western Ontario McMasters Universities Osteoarthritis Index (no pain=10; mild pain=28; moderate pain=17). Radiographic disease severity was graded by Kellgren and Lawrence scale (KL2=29; KL3=21; KL4=5). Hip kinematics variability was estimated as the curve coefficient of variation. Vector coding was used to calculate coordination variability for select joint couplings. One-way ANOVAs with planned adjusted post-hoc comparisons were used to compare hip kinematics variability and coordination variability of select segment couplings (pelvis sagittal vs. thigh sagittal; pelvis frontal vs. thigh frontal; pelvis transverse vs. thigh transverse; thigh sagittal vs. shank sagittal; thigh frontal vs. shank sagittal; thigh transverse vs. shank sagittal) according to pain and radiographic disease severity. No main effect of pain severity was observed for sagittal or transverse plane hip kinematic variability (p≥0.266), and although there was a main effect for frontal plane hip kinematic variability (p=0.035), there were no significant differences when comparing between levels of pain severity (p>0.006). There was no main effect of radiographic disease severity on hip kinematic variability in the sagittal (p=0.539) or frontal (p=0.307) plane. No significant differences in coordination of variability of segment couplings were observed (all p≥0.229). Movement variability as assessed in this study did not differ according to pain severity during walking or radiographic disease severity.
