This study was designed to determine the effects of swimming and low power laser on rheumatoid arthritis in Sprague-Dawley rats. Rheumatoid arthritis was induced in 36 rats among 48 Sprague-Dawley rats by the subcutaneous injection of .05 ㎖, Freund’s Complete Adjuvant into the right hind paw and .05 ㎖, Freund’s Complete Adjuvant into the right hind knee joint capsule. A second injection was performed by the same method using .1 ㎖ Freund’s Complete Adjuvant per a rat. Arthritic rats were divided into 8 groups: each 1 week and 2 weeks of arthritic swimming, arthritic laser, arthritic case control and normal group. In this study, several experimental tests were performed to determine the concentration of Interleukin-6, the space of the knee joint and the thickness of the hind paw. The concentration of Interleukin-6 and hind paw thickness decreased in the swimming group and laser group as compared to the control group. The space of the knee joint increased significantly after the swimming exercise. Swimming and low power laser therapy positively affect rheumatoid arthritis in rats affect by decreasing the concentration of Interleukin-6 and hind paw thickness, and increasing the space of the knee joint.
