Cervical Manipulation (OAA Technique) in Exophories

Not Applicable

Completed

• Conditions: Exophoria

• Registration Number: NCT04901533
• Lead Sponsor: University of Seville

Brief Summary

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.

Primary Outcome Measures

Name	Time	Method
exophoria with cover test at 40 cm	Changes from baseline to moment after intervention	The exophoria will be evaluated in prismatic diopter.; Using the cover alternate test, therapist will measure with a prism ruler the diopters that the subject requires to balance eye movement and that the eye does not move from the outside to the inside when looking at an object at 40 cm.
exophoria with cover test al 4 m	Changes from baseline to moment after intervention	The exophoria will be evaluated in prismatic diopter. Using the cover alternate test, therapist will measure with a prism ruler the diopters that the subject requires to balance eye movement and that the eye does not move from the outside to the inside when looking at an object at 4 meters.

Secondary Outcome Measures

Name	Time	Method
exophoria with cover test at 40 cm (2)	Changes from baseline to 1 week after intervention	The exophoria will be evaluated in prismatic diopter. Using the cover alternate test, therapist will measure with a prism ruler the diopters that the subject requires to balance eye movement and that the eye does not move from the outside to the inside when looking at an object at 40 cm.
