Methods Nineteen able-bodied subjects walked four different conditions (control, effusion, pain, and pain+effusion), with a week between each condition. We used previouslyused injury models of pain [1] and joint effusion [2] to the right side of the knee. The control condition consisted of no injection. For each condition, subjects completed three walking trials at three times: precondition (prior to injection(s)), condition (3 minutes post injection(s)), and postcondition (30 minutes post injections). We used a standard inverse dynamics approach (combining high speed video, ground reaction force, and anthropometric
