Aim of investigation: This study investigated the antinociceptive and anti-inflammatory effects of different grades of joint mobilization (JM) at different periods of time after induction of inflammation. Methods: Seventy five male Wistar rats were induced with joint inflammation through an injection volume with 0.1 mL of 3% carrageenan and kaolin at the left knee. Later, they were divided into groups of joint mobilization grade 1, grade 3 and control. Animals were assessed at different periods as 5 days before induction, 07 hours after induction, and 03, 10 and 20 days after induction of inflammation. Joint mobilizations were held for grades 1 and 3 differentiated by the degree of range performed and where clinically indicated for pain reduction and improved mobility. The protocol of JM was performed by using three sets of three minutes with one minute of interval between each series. Control animals were maintained in a glove for the duration of therapeutic intervention. All tests were performed with the investigator blinded to treatment. Mechanical hyperalgesia, and motor performance were assessed through digital analgesimeter and grip strength meter, respectively. Anti-inflammatory action was assessed by the total cell counting. Results: All experimental groups became hyperalgesic, through a significant reduction in mechanical withdrawal threshold (p<0.001) 24 hours after the inflammation was induced. There was no change in the mechanical withdrawal threshold in the experiment where the JM was done before induction. There were antinociceptive effects in the other groups, when compared with control (p<0.05). There was a significant reduction of the total cells counting only in the group treated with grade 1 JM when compared to the group treated with grade 3 and to the control group (p<0.0001). There was no difference for the withdrawal threshold between grades 1 and 3 JM related to the experiments assessed 03, 10 and 20 days after induction of inflammation, and for the 7-hour after induction group, only grade 1 mobilization showed antinociceptive effect (p<0.001). There was no difference between groups related to motor performance. Conclusions: Both grade 1 and grade 3 JM were effective in reducing secondary hyperalgesia after joint inflammation, and grade 1 was more effective in suggesting anti-inflammatory effect in joint inflammation.
