After a 7 day washout, synovitis was induced in the contralateral carpus, and the alternate treatment was administered. Evaluations occurred prior to and at 4, 6, 8, 12, 24, 36, and 48 h after synovitis, including physical, lameness, and neurologic exams, pain scoring, mechanical threshold testing, and joint circumference measurement. Mixed\u2010model linear regression was used to assess the effects of time, treatment, and their interaction, with horse as a random effect.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      All DM\u2010treated horses became sedate, and four of five developed hypermetria and ataxia.
