Objective: The purpose of the study was to analyze the upper trapezius muscle temperature using thermography in women with and without neck pain.
Methods: Thirty-six female university students were classified through the Neck Disability Index (NDI) into 2 groups: the neck pain group comprised 18 volunteers diagnosed with mild disability, and the control group, 18 healthy volunteers. All subjects were submitted to evaluation by thermography, which registered the skin surface temperature of the upper bilateral trapezius muscle.
