Place the laser in a plastic bag and laser directly inside the mouth.
Or place the XLR8 over the cervicals and then over the area of involvement (AOI).
If symptom or soreness is not visual in open mouth lasering on the outside of the neck/throat will be suffice.
Refer to the Laser Essentials Video for standard myotome testing C1 - C4 and C5-T1 and upregulate.
