Effect of low-level laser therapy on the expression of inflammatory mediators and on neutrophils and macrophages in acute joint inflammation

Table 1 Low-level laser therapy parameters

Group	λ(nm)	Type of diode laser	Mean power output (mW)	Spot size (cm²)	Power density (W cm²)	Energy (J)	Energy density (J cm²)	Time per point (seconds)
50 mW LLLT	808	GaAlAs	50	0.028	1.78	4	142.4	80
100 mW LLLT	808	GaAlAs	100	0.028	3.57	4	142.4	40

GaAlAs - arsenide and aluminum gallium; λ, - wavelength; LLLT - low-level laser therapy.
