Terapia laser (AsGa) na sinovite aguda experimental em pôneis

Abstract

An experimental synovitis model of the radio-carpal joint was induced in 8 male intact ponies with an intra-articular injection of 0.25ml of Freund s complete adjuvant. Four ponies had the affected joint irradiated with a 4J/cm2 of laser in a cranio-caudal direction. The control group received the same technique with the device turned off. The heart rate was lower (p<0.05) in the treated group (37±6.9) than in the control group (41.2±5.7). The carpal angle of maximum flexion was significantly (p <0.05) lower in the treated group (94.4±27.2) than in the control group (125.6±5.3). The results of this study show that treatment with laser of gallium arsenide, in the dose of 4J/cm2, presented analgesic effect and improved joint movement in this model of Freund s adjuvant induced acute synovitis.
