About this study

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.

Who can participate

Healthy volunteers accepted: Yes

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Intraocular pressure below 21mmHg

Exclusion criteria

  • Positive Klein test
  • Use of medications that affect the circulatory system in up to one month before the procedures;
  • Caffeine use 24 hours before procedures;
  • Presence of ophthalmic diseases;
  • History of hypertension or diabetes;
  • Blindness;
  • Tumor in the head;
  • Skull or cervical fractures that occurred less than 6 months ago.

Treatment and study plan

Upper cervical manipulation

Other

The patient will receive an upper cervical manipulation as described in the Experimental Group 1.

Sphenopalatine ganglion manipulation

Other

The patient will receive a sphenopalatine ganglion as described in the Experimental Group 2.

Primary outcomes

  1. Change of the intraocular pressure after upper cervical manipulation

    Time frame: 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.

  2. Change of the intraocular pressure after sphenopalatine ganglion manipulation

    Time frame: 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.
