Intervention type: PROCEDURE
Group type: ACTIVE_COMPARATOR
Intervention: Maitland C2
Description: Maitland central posterior-anterior passive joint mobilization at C2: The patient will lie prone, the therapist behind the patient's head, with both thumbs will apply a central force on the spinous process of C2. The duration of the application will be up to five applications of 10 to 30 seconds in duration, depending on clinical judgment.

Intervention type: PROCEDURE
Group type: ACTIVE_COMPARATOR
Intervention: SNAG C1
Description: Sustained natural apophyseal slippage (SNAG) will be applied e.g. in the case of wanting to improve the left rotation. The therapist performs a sustained anterior glide to the C1 transverse process on the left. The participant will be seated, simultaneously rotating their head to the left while holding the SNAG. The glide of C1 will be maintained by the therapist until the participant's head returns to the neutral starting position. The same will be done, but in the opposite direction to improve the right rotation.

Group type: EXPERIMENTAL
Intervention: Specific joint mobilization post muscle inhibition on C2
Description: The therapist rotates the head to the right side until the final sensation of the movement is noted, either due to pain or muscular tension. From this position, the therapist asks the patient to rotate the head to the left side while offering resistance with both hands in the opposite direction, in such a way as to generate an isometric contraction of the rotator muscles of the head to the left. The therapist then asks the patient to hold the position for 6 seconds. Subsequently, the therapist with the finger in the transverse process of C1, pushes it in the postero-anterior direction and simultaneously (with the contratome hand) rotates the patient's head to the right. The technique is repeated until the ROM improves, always taking into account the patient's tolerance.

Group type: EXPERIMENTAL
Intervention: Myofascial inductions; Suboccipital induction
Description: The therapist places his hands under the patient's head in such a way that he can palpate the spinous processes of the cervical vertebrae with his fingers. Next, slowly bring your fingers up until they contact the occipital condyles. At this time he should gently move his fingers downward, thus finding the space between the condyles and the spinous process of the axis. Next, flexing the metacarpophalangeal joints to 90°, slowly elevate the skull. The therapist's hands should remain together and the base of the skull should rest on their palms. The therapist should apply pressure with the index, middle and ring fingers of each hand. This pressure should be maintained for a few minutes until a release of the fascia is noted. In the last phase of the technique, the therapist, without releasing the pressure, opens his hands and slowly brings his head back.

Group type: EXPERIMENTAL
Intervention: Myofascial inductions; Synchronization of the temporal bones PHASE 1
Description: The therapist rests his two forearms on the table, in such a way that he can contact the external auditory canal with his middle fingers. Place the ring fingers on the mastoid processes and the index fingers on the zygomatic arches. Subsequently, a rotary movement is made on the axis marked by the line that joins the middle fingers. With one of the hands, the movement is in the direction of movement clockwise, and with the other hand, simultaneously, in the opposite direction. By obtaining a symmetry in the movement in opposite directions, the movement is made in the same direction with both hands, first forwards and then backwards. Note how the ring fingers rotate first backwards and then upwards. Symmetry in movements should also be sought

Intervention type: PROCEDURE
Group type: EXPERIMENTAL
Intervention: Myofascial inductions; Horizontal induction of the TMJ.
Description: The therapist places the middle fingers of both hands on the lingual aspect of the lower molar teeth and then gently presses towards the table. This pressure must be maintained for a minimum of 90 to 120 seconds. Afterwards, the therapist, very attentive to the changes in the direction of the fascial restriction, follows the release movement.
