Inclusion Criteria

The inclusion criteria will be unilateral latent trigger points within the upper trapezius muscle.

Exclusion Criteria

The exclusion criteria will be: (i) rheumatologic or neurological diseases and other serious medical conditions, real pain problems of the shoulder girdle and neck (because of the measurement methods of electrodermal skin resistance); (ii) surgery or/and post-traumatic incidence of the upper extremity and neck; (iii) diabetic problems; (iv) current use of some pain killers and other pharmacotherapies; (v) dermal problems of the upper back skin.
