on bone as well as cartilage material throughout joint immobilization was taken a look at with rats’ knee model. The back limbs of 42 young Wistar rats were operated in order to debilitate the knee joint. They were designated to three teams 1 wk after procedure; irradiance 3.9 W/cm2, 5.8 W/cm2, as well as sham treatment. After 6 times of treatment for an additional 2 wk both back legs were planned for 1)impression of the articular surface area of the knee (tightness and also loss tangent), and also for 2) twin energy X-ray absorptiometry (bone mineral density)of the focused regions. The imprint examination revealed conservation of articular cartilage rigidity with 3.9 and also 5.8 W/cm2 therapy. Soft laser treatment might potentially avoid biomechanical changes by immobilization.
