Interventional
Description of intervention(s) / exposure
The study will be carried out in single rehabilitation center.

The intervention was performed by a physiotherapist with more than 5 years of experience in manual therapy.

Intervention: Upper cervical spine manipulation; A single HVLA thrust manipulation directed to the upper cervical spine (C1-C2) with the patient supine was performed. For this technique, the patient’s left posterior arch of the atlas was contacted with the lateral aspect of the proximal phalanx of the therapist’s left second finger using a “cradle hold.” To localize the forces to the left C1-C2 articulation, secondary levers of extension, posterior-anterior shift, ipsilateral side-bend, and contralateral side-shift were used. While maintaining the secondary levers, the therapist performed a single HVLA thrust manipulation to the left atlanto-axial joint, using the combined thrusting primary levers of right rotation in an arc toward the underside eye and translation toward the table. This was repeated using the same procedure but directed to the right C1-C2 articulation.

Data Collection Protocol: The participants were evaluated and intervened in three different sessions (1st session: after signing the informed consent, 2nd session: 7 days after the start, 3rd session: 15 days after the start). The intervention was carried out five minutes after the evaluation and the re-evaluation process began five minutes after the intervention. The order carried out during the data collection protocol was always the same in each of the sessions held both before and after the intervention, with the exception of the disability, which was collected only in the first and the last session. In each session the range of motion was measured first and then the neck pain, before and after the intervention.
Prior to the intervention, all participants will sign the informed consent.

Comparator / control treatment
Cervicothoracic spine manipulations; Patients in this group received three different spinal manipulations:
• Upper thoracic spine manipulation: patients were supine with the arms crossed over the chest and hands placed over the shoulders. The therapist placed their chest at the level of the patient’s middle thoracic spine and grasped the patient’s elbows. Flexion of the thoracic spine was introduced until slight tension was felt in the tissues at the contact point. A distraction thrust joint manipulation in an upward direction was applied. If no popping sound was heard on the first attempt, the therapist repositioned the patient, and performed a second manipulation. A maximum of 2 attempts were allowed on each patient.
• Cervicothoracic junction manipulation: this technique was applied bilaterally. Here we describe the procedure for a right C7-T1 thrust joint manipulation, that is, the contact was on the left side of the cervico-thoracic junction. The patient was prone with the head and neck rotated to the right. The therapist stood on the right side of the patient facing in a cephalic direction. The therapist’s left hand makes contact with the thumb on the left side of the spinous process of T1. The therapist’s right hand supports the head of the patient. The head/neck is gently laterally-flexed to the left, until slight tension is palpated in the tissues. A HVLA thrust was applied toward the patients’ right side. Again, a maximum of 2 attempts were allowed for each side.
• Mid-cervical spine manipulation: the subject was supine with the cervical spine in a neutral position. The index finger of the therapist applied a contact over the posterior-lateral aspect of the zygapophyseal joint of C3. The therapist cradled the patient's head with the other hand. Ipsilateral side-flexion and contralateral rotation to the targeted side was introduced until slight tension was perceived in the tissues at the contact point a HVLA thrust manipulation was directed upward and medially in the direction of the patient’s contralateral eye. Similarly, a maximum of 2 attempts were allowed for each side to obtain cavitation.

The duration of the study, the number of sessions and the data collection protocol followed in this group were the same as in the experimental group.

Summary
Brief summary
The aim of the study is to compare the effectiveness of hight-velocity low-amplitude (HVLA) spinal manipulation in the atlantoaxial joint (C1-C2) with a combination of HVLA spinal manipulation on the cervicothoracic spine (C3-C4, C7-T1 and T6) and its influence on the range of motion, neck pain and disability in patients with chronic mechanical neck pain.
Study Design: Randomized controlled trial.
Setting: Single rehabilitation center.
Participants: Ninety (n=90) patients diagnosed with chronic mechanic neck pain were randomly divided into two groups: the upper cervical spine (UCS) manipulation group (n=45) and cervicothoracic spine (CTS) manipulations group (n=45). All participants completed the interventions and follow-up evaluations.
Interventions: A single C1-C2 spinal manipulation technique was performed in the group 1, whereas the group 2 received a combination of HVLA spinal manipulation on the cervicothoracic spine (C3-C4, C7-T1 and T6).
Main Outcome Measures: Measures included assessing the neck disabiliy using the Neck Disability Index (NDI). Subsequently, the outcome measures that included the cervical range of motion using a Cervical Range of Motion (CROM) device and neck pain using a Numeric Pain Rating Scale (NPRS) were performed.
Results: The intra-group comparison indicated a significant improvement in ROM in both groups (p<0.05). An improvement in neck pain was observed inmediately after the interventions. We also observed a decrease in pain and NDI after 15 days of treatment. In the between-group comparison of the mean differences from pre- to post-intervention, there was no statistical significance for all variables.
Conclusions: Both upper cervical spine manipulation and cervicothoracic spine manipulations increase the cervical range of motion and decrease neck pain and disability in patients with chronic mechanical neck pain.
