Chronic Mechanical Neck Pain
Conditions
Brief summary
The aim of the study is to compare the effectiveness between the suboccipital inhibition technique, the suboccipital inhibition carried out with the INYBI instrument and the suboccipital inhibition with the INYBI plus the upper cervical manipulation, all in patients with chronic mechanic cervicalgia, and to determine which of these techniques is the most effective in the variables studied. In order to do so, 96 subjects participated in the study, being assigned to the 3 intervention groups. We expected the combined treatment (INYBI instrument + upper cervical manipulation) to be the one to produce the best results.
Interventions
The therapist will seat at the patient's head height and place his second, third, fourth and fifth fingertips'over the patient's suboccipital area during a 10-minute period.
OTHERINYBI
The therapist will place the INYBI at the suboccipital area, specifically placing the fingers of the instrument at the lower border of the occipital. If needed, a rolled towel will be placed behind the INYBI, in order to maintain the physiological lordosis, checking out that the patient doesn't make a cervical extension. Then the therapist will press the vibration button and turn it off after 10 minutes. All patients will receive the treatment with the INYBI's hardest head with a 50 HZ frequency.
OTHERINYBI + upper cervical manipulation
The participant will also be treated with the INYBI during a 10-minute period. After that, the therapist will carry out the upper cervical manipulation technique. Keeping the patient's head on an upper cervical flexion position, the therapist will turn his/her head to the maximum possible rotation, always maintaining its longitudinal axis. Once this is done, a high velocity and short articular amplitude manipulation in rotation will be carried out

Inclusion criteria
* Participants aged between 18 and 40 all diagnosed with chronic mechanic cervical pain with an evolution of at least 3 months and who show pain that increases with maintained postures, during movement and during spinal muscles palpation.
Exclusion criteria
* participants that can't read and/or fill in the informed consent, either due to a language and/or cognition alteration or age-related factors. * subjects with psychological pathologies, such as hysteria, depression or anxiety. * subjects that have received a manual treatment two months before the beginning of the clinical trial. * subjects who have been recommended by a physician or an anesthetist to receive any type of analgesic, anti-inflammatory or neuromodulator medication, such as antidepressants, antiepileptics and benzodiazepines. If the patient took in this type of medication in an occasional way 72 hours before the beginning of the study, he/she could participate. * the treatment and assessment techniques will be avoided if: fear to vertebral manipulation in the upper cervical area or positive Klein test and other integrity test of the vertebral artery, positive cervical instability test and positive Spurling test (foraminal compression test).
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Changes in patients' cervical functionality between baseline and follow-up period. | Baseline and two weeks after the second intervention. | cervical functionality is measured with the Neck Disability Index |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Changes in patients' cervical mobility between baseline and follow-up periods. | Baseline, 10 minutes after the first intervention, 1 week after the first intervention and 10 minutes after the second intervention. | The movements that will be measured with the CROM® are: flexion, extension, right and left rotation, right and left side-bending. |
| Changes in patients' pressure pain threshold between baseline and follow-up periods. | Baseline, 10 minutes after the first intervention, 1 week after the first intervention and 10 minutes after the second intervention. | The pressure pain threshold will be measured with an algometer (Mechanical Algometer Pain Test® de Wagner Instrument, USA) in the suboccipital and trapezius muscles (both left and right). |
| Changes in patients' pain due to movement between baseline and follow-up periods. | Baseline, 10 minutes after the first intervention, 1 week after the first intervention and 10 minutes after the second intervention. | The movements that will be measured with the visual analogue scale (VAS) are: flexion, extension, right and left rotation, right and left side-bending. |
