November 21, 2021 updated by: Rodolfo Amoroso Borges, Federal University of São Paulo

Effect of Osteopathic Techiniques on Intraocular Pressure: a Randomized Double-blind Clinical Trial

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.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

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.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 60 years (Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Upper cervical manipulation group
The patient will be in the supine position. The cephalic hand will make contact with one side of the patient's skull, leaving the sternocleidomastoid muscle between the third and fourth fingers. The caudal hand will make global contact with the patient's skull on the opposite side. The therapist should place his torso on the patient's head, leaving the two forearms aligned with the axis of the patient's spine, as this technique is applied to the axis of the odontoid process of the ax. With neutral flexion-extension the therapist will place the rotation parameter to the opposite side (70-80 degrees) and a small contralateral inclination. Then it will search for the driving barrier with a small axial traction movement. When the driving barrier is found, the thrust should be applied in a helical direction, increasing rotation and traction. It will be applied bilaterally.
Other: Upper cervical manipulation
The patient will receive an upper cervical manipulation as described in the Experimental Group 1.
Experimental: Sphenopalatine ganglion group
The patient will be supine on the bench and the therapist with gloves will sit next to the patient contralateral to the manipulated sphenopalatine ganglion (SPG). One of the therapist's hands will be placed flat in contact with the apex of the patient's head to stabilize it. The patient will be instructed to open his mouth and deviate the mandible laterally to the same side of the ganglion to be treated. The therapist will then apply pressure to the SPG with the fifth finger of your other hand in the patient's mouth, moving up along the alveolar process of the maxilla teeth to reach the pterygoid process. The therapist will keep the patient's head elevated until the lateral pterygoid muscle relaxes. Then, the pressure will be applied into the pterygopalatine fossa. The therapist will then apply gentle pressure on the SPG with the pulp of the fifth finger until tissue relaxation. He will then release the contralateral SPG in the same way.
Other: Sphenopalatine ganglion manipulation
The patient will receive a sphenopalatine ganglion as described in the Experimental Group 2.
No Intervention: Control Group
The patient will lie down on the bench for 10 minutes.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
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.
Immediately after the intervention and 30 minutes after the intervention
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.
Immediately after the intervention and 30 minutes after the intervention

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
