Each volunteer selected in this group will complete a scale, in this case Hit-6, to collect data and evaluate the evolution.

Then a placebo technique will be used, which consists of imitating the contacts of the techniques without compressing or pulling the tissue, lasted 6 minutes.

This procedure will be repeated for two more sessions. One month after the first evaluation, the volunteers filled out the Hit-6 scale again.

After each volunteer completes the Hit-6 scale, one of the researchers will perform the "trapezius and sternocleidomastoid stretching techniques", and "suboccipital inhibition". The techniques performed will only be done once, lasted 6 minutes.

This procedure will be repeated for two more sessions. One month after the first evaluation, the volunteers filled out the Hit-6 scale again.

For the technique performed in the control group, the researcher will come into contact with the volunteers' chests. This contact will be maintained for the same period of time as the experimental group (6 minutes).

The scale Hit-6 will be the instrument used to evaluate the level the intensity and frequency of tension headache. This instrument consists of six questions about the characteristics of headaches, with each question presenting five choices. The answers range from never to always. This data will be collected immediately before the first investigation and one month after the first evaluation, through the volunteers filling out the scale.
