Effects of Two Sub-occipital Techniques on Limited Mobility According to the Flexion-rotation Test

Study Overview
=================
Brief Summary
-----------------
The cervical spine should work as a functional unit. If hypomobility should exist in any of the segments it would limit the mobility of the spine as a whole. Although it is frequent that certain cervical segments present hypomobility, they are not always related to symptomatology. The effects of inhibition sub-occipital techniques on cervical mobility have not been evaluated. The objetive of this trials is to assess and compare the effects on cervical mobility, of the manual technique of sub-occipital inhibition by applying pressure and self-treatment by way of Occipivot® cushion, in subjects with no cervical symptomatology but with limited mobility assessed by the flexion-rotation test.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Manual technique of sub-occipital inhibition<br>The technique applied to Manual Group was performed with the patient supine position. Physiotherapist in a sitting position at the head of the subject with forearms resting on the table . Suboccipital region was located , and flexing the metacarpophalangeal joints 90º a pressure was made ventrally , relaxing the rest of the head in the heel of the hand. The technique was performed for 5 minutes | Other: Manual technique of sub-occipital inhibition<br> <br> |
| Experimental: Self-treatment by way of Occipivot®<br>The technique applied to the Instrumental Group was performed with the patient supine in the same position as the Manual Group . It was previously instructed the subject how to proceed with the cushion Occipivot® , indicating the installation location and method of affixing , correcting him if the application was inadequate. The subject placed the cushion Occipivot® under the suboccipital region and told him he had to stay in that position for 5 minutes. A physiotherapist warned the patient at the end of the application time so that the subject had to be aware not to control it. | Other: Self-treatment by way of Occipivot®<br> <br> |
