Model: Partial incision (tenotomy) of the left Achilles tendon
Low-level laser therapy significantly reduced IL-1beta at all three time points (6 h P=0.0401; 24 h P=0.0015; 72 h P=0.0463), reduced IL-6 significantly only at 72 h (P=0.0179), and significantly increased IL-10 at all three time points (6 h P=0.0007; 24 h P=0.0256; 72 h P<0.0001).
