intraocular pressure, sphenopalatine ganglion, superior cervical ganglion, aqueous humour
Brief summary
The purpose of this study is to assess the effects osteopathic techniques at the upper cervical vertebrae or at the sphenopalatine ganglia on the intraocular pressure.
Detailed description
The 7 volunteers will be randomized into 3 groups and there will be an experimental group 1 that will receive a technique of manipulation of the upper cervical, an experimental group 2 that will receive a technique of manipulation of the sphenopalatine ganglion and a control group that will not receive any intervention. Each volunteer will participate in the 3 groups. There will be 4 assessments, one before the procedure and one just after each procedure, including the control.
Interventions
The patient will receive an upper cervical manipulation as described in the Experimental Group 1.
OTHERSphenopalatine ganglion manipulation
The patient will receive a sphenopalatine ganglion as described in the Experimental Group 2.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change of the intraocular pressure after upper cervical manipulation | Immediately after the intervention and 30 minutes after the intervention | After this manipulation, it is expected that there will be a sympathetic response increasing the intraocular pressure. |
| Change of the intraocular pressure after sphenopalatine ganglion manipulation | Immediately after the intervention and 30 minutes after the intervention | After this manipulation, it is expected that there will be a parasympathetic response decreasing the intraocular pressure. |
