Change of knee joint angle in the inflamed ipsilateral knee joint during a complete walking cycle measured in representative animals from each treatment group. (A) Immunized control, no AIA. ROM is defined as the difference (in degrees) between the maximum and minimum knee joint angles reached during a complete step cycle. (B) AIA, saline treatment. (C) AIA, morphine treatment. (D) AIA, dexamethasone treatment. AIA: antigen-induced arthritis; ROM: range of motion.
