Details and patient eligibility

About

Objetive: to assess the efficacy of the occipito-atlas-axis cervical manipulation technique to correct ocular divergence in subjects with exophoria.

Design: quantitative, experimental, longitudinal and prospective study.

Subjects: subjects over 18 years of age, with exophorias, without heterotropies and who do not present a contraindication to cervical manipulation.

Methods:Subjects with this ocular mobility dysfunction are going to be evaluated objectively with the Alternate Cover Test. The ocular deviation will be measured at 40 cm and at 4 meters. The individuals who were part of the experimental group underwent the OAA manipulation technique, and to those who were part of the control group a placebo maneuver. Two measurements were taken from this moment, one immediately after the execution of the technique and another one week later.

Enrollment: 44 patients

Sex: All

Ages: 18 to 57 years old

Volunteers: Accepts Healthy Volunteers

44 participants in 2 patient groups

cervical manipulation

Experimental group

Description:

The objective of this technique is to restore joint mobility between the joints of the occipital, first (atlas) and second cervical vertebra (axis). It is a technique performed in rotation on a vertical axis that passes through the odontoid process of the axis, without placing flexion or extension, and with very slight sidebending; it is done bilaterally.

Treatment:

Procedure: O-A-A

Cranial Listening

Active Comparator group

Description:

Cranial palpation maneuver

Treatment:

Procedure: cranial listening
