The Maitland technique will be applied, central postero-anterior passive joint mobilization in the C2 vertebra. As well as the sustained apophyseal slip technique (SNAG) in rotation on C1. The dosage is from 1 to 5 mobilizations per technique. There will be 4 treatment sessions distributed over 2 weeks.

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.

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.

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.

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.

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

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.

Position of the patient, lying on the stretcher in the supine position. Therapist position: Sitting at the head of the table. Technique: With one of his hands, the therapist supports the patient's head on the occipital area and slowly brings it to flexo-elevation. With the other hand, he contacts the mass of the paravertebral muscles, placing the thumb on one side of the spine and the proximal interphalangeal joint of the index finger in flexion on the other. While one hand holds the head position, the other performs a downward vertical slide. The maneuver is repeated between 3 and 7 times in a slow and progressive manner.

Position of the patient, supine position, with the arm resting along the trunk. Position of the therapist, standing or sitting at the head of the table. The therapist places one of his hands under the shoulder blade, embracing the lower angle with the fingertips and bringing it slightly cranially. This maneuver frees access to the superior angle of the scapula, which makes it easier for the index and middle fingers of the other hand to contact the insertion of the angle. More sustained pressure is applied to this point, while the hand placed on the scapula moves in the direction of release.

Objective, release the myofascial restrictions of the fascia of the SCM muscle. Position of the patient, supine position with the head near the upper edge of the stretcher. Therapist position. sitting at the head of the stretcher. Technique: The therapist, with one hand placed on the occipital region, gently rotates the patient's head. The other hand places it on the mass of the SCM muscle with the thumb at the point of insertion on the mastoid process. While one hand applies the rotational movement and a slight extension of the head, the other performs a transverse slide over the zone of restriction in the SCM muscle. A longitudinal sliding movement of the SCM muscle can be made between the thumb and forefinger of the executing hand.

Objective, release the fascia of the pectoralis major and minor muscle. Position of the patient, supine position, with the arm abducted to about 120 degrees. Position of the therapist, standing next to the patient, at head height. Technique: with his cranial hand, the therapist holds the patient's arm, and with the caudal hand, placed in a prone position, contacts the space between pectoralis major and ribs. This contact is made with the fingertips. The pressure should be maintained for about 5 minutes. As the release occurs, both of the therapist's hands must adjust to the direction of the changes. When detecting the restriction in the pectoralis minor, the penetration should be deepened with the hand, sliding it over the ribs. Contact and restraints with the pectoralis minor and major are often particularly painful, forcing the therapist to apply controlled force.

Objective, release the myofascial restrictions of the upper trapezius. Position of the patient, supine, with the elbow flexed and the hand resting on the abdomen, and the arm in a slight abduction. Therapist position, sitting at the head of the table. Technique: The therapist places his hand on the patient's shoulder so that he can grasp the fibers of the upper trapezius between the index, middle, and ring fingers above and the thumb below. Subsequently, he exerts gentle and sustained pressure overcoming three restraining barriers.

Position of the patient, supine, with the arm raised about 90-160 degrees, depending on the degree of movement restriction. Therapist position, standing at the head of the table. Phase A With his cranial hand, the therapist holds the patient's arm and performs very gentle traction. The palm of the caudal hand, thumb up, is placed on the outer edge of the scapula, as close as possible to the glenohumeral joint. A slight traction is performed with both hands in opposite directions, subsequently following the direction of release. Phase B, The thumb of the caudal hand slightly invades the space between the inner aspect of the scapula and the thorax. The rest of the application is performed as in phase A. Phase C, the therapist places his caudal hand in a prone position and slowly penetrates the aforementioned space with the tips of the fingers. sustained for a time ranging between 90 seconds and 5 minutes, following the release stages.

Position of the patient, supine position, on the stretcher without the pillow. Position of the therapist, sitting at the head of the table. Technique: The therapist, with the index of his hand, contacts the masseter just below the zygomatic arch and inside the mouth. To ensure proper contact on the masseter, the patient is asked to attempt to close the mouth. Once the muscle is correctly located, the patient should immediately relax the masseter. Next, the therapist compresses the masseter between his index finger and thumb. You have to wait long enough for the release to occur. Sometimes both hands are used by placing the forefinger of the other hand on the outer surface.

Objective, release the myofascial restrictions and recover the functional coordination of the external pterygoid muscles.

Position of the patient, supine position, on the stretcher without the pillow. Therapist position, sitting at the head of the table. Technique: The therapist palpates the temporomandibular joint with the index or middle finger of one hand. With the index finger of the other hand, he contacts the pterygoid inside the mouth and maintains pressure until release occurs.

Objective, release the restrictions of the internal pterygoid fascia. Position of the patient, supine position on the stretcher. Therapist position, sitting laterally at the head of the stretcher and looking at the patient. Technique: Therapist palpates the TMJ with the index or middle finger of one hand. With the index of the other hand, he contacts the pterygoid inside the mouth and maintains pressure until release occurs. You have to wait three consecutive releases.

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.
