The group was perform the technique inhibition suboccipital two minutes, collecting data by measuring with algometer and test repositioning of the head before and after the technique.

The group was perform the technique inhibition suboccipital four minutes, collecting data by measuring with algometer and test repositioning of the head before and after the technique.

The group was perform the technique inhibition suboccipital eight minutes, collecting data by measuring with algometer and test repositioning of the head before and after the technique.

The not intervention group will be asked to lie supine on the table for ten minutes, collecting data by measuring with algometer and test repositioning of the head before and after laying.

Suboccipital inhibition technique involves the placement of the hands of the physiotherapist under the patient's head so that fingers can feel the spinous processes of the cervical vertebrae. Then fingers slowly leads upward to contact the occipital condyles. At this point the investigator should gently move your fingers down, finding the space between the condyles and the spinous process of the axis. Remember that the atlas has no spinous process. Then, flexing the metacarpophalangeal joints at 90 degrees, slowly raises the skull

Three measurements were performed with a rest period of 30 seconds between each measurement.

a target is placed on the wall in front of the subject at a distance of 90 cm and adjusted to align with the reference position of the head. a helmet with a laser on top is used. For each test subjects will be instructed to memorize the initial reference position by carrying out a maximum cervical rotation and returning to the reference position without speed limit. Subjects undertake 10 trials. Before each test, the examiner manually reposition the subject's head to the reference position. Once the subject is instructed to conduct the test measurement.
