Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Group B & Group C
Group B equal to low-level laser therapy dosis 5,9 j per point Group C equal to Placebo group
Laser
The laser will be used 830 nm, 30 milliwatts twice a week: the initial dosage will be 5.9 J per point. The irradiation will be performed bilaterally on the belly of the trapezius muscle as well as 2 cm to the right and left and 2 and 4 cm below the belly of the muscle.
Placebo
To provide the "blinding": the laser equipment has two identical application points furnished by the manufacturer - one active and the other a placebo (does not emit energy).
Group A & Group C
Group A equal to Control (no intervention) Group C equal to Placebo group
No interventions assigned to this group
