Parameters were measured in control (n = 8) and adjuvant-induced arthritis (AIA) rats (n = 18) at day 195 post-immunization. The more and less impaired hemibodies corresponded to hemibodies with the highest and lowest hind-paw diameter just before the locomotion recording, respectively. Values are means ± SD. aSignificantly different from control rats (p <0.05)
