Treatment of Tension Headache Using Soft Tissue Techniques VS Vagus Stimulation Techniques.

Tratamiento de la Cefalea Tensional Mediante técnicas de Tejido Blando VS técnicas de estimulación Del Vago.

A treatment based on manual therapy and vagus nerve stimulation is more effective than manual therapy only to reduce frequency, intensity and pressure pain threshold in patients with tension type headache.

Participants will be randomly assigned to two groups:

• Experimental group, to which soft tissue techniques and vagus nerve stimulation techniques will be applied.
• Control group, to which only soft tissue techniques are applied. Treatment will consist of four sessions, with an interval of seven days between them, for both study groups. Each session with a duration of 20 minutes for both groups.

In the control group, treatment using soft techniques will consist of the application of manual techniques that have already been shown to have some efficacy in other studies.
