Official title
"Effect of Oculomotor Therapy in Individuals With Convergence Insufficiency: A Blind Randomized Clinical Trial"
Overview
The aim of this study is to investigate the effect of oculomotor therapy in individuals with ocular convergence insufficiency.
Detailed description
Seventy participants with convergence insufficiency (CI) will be randomly allocated into two groups: Experimental Group (EG) (n=35) and Control Group (CG) (n=35). The primary outcome will be CI assessed by the convergence test. Secondary outcomes will include quality of life, postural balance, and gait speed. The EG will undergo five sessions of oculomotor therapy (once a week), based on and adapted from the established protocol for CI treatment. Results: Outcomes will be assessed by blinded evaluators at baseline, one week after the end of the treatment, and at 1 and 3 months follow-up. The CG will not receive any intervention. Data will be analyzed using statistical tests with a significance level set at p \< 0.05.
Interventions
- Other Oculomotor therapy
Oculomotor therapy will follow and adapt the protocol for treating convergence insufficiency (CI). Procedures will be organized progressively, from easiest to most difficult. Gross convergence techniques: (1) Brock String: A 1.5-2 m cord with colored beads; the patient focuses on each bead to train binocular fusion, observing the "X" shape of the cord. (2) Barillé Chart: A card with paired images for each eye; the patient merges the images into one using convergence and sensory fusion. Accommoda - Other No Treatment Added
Participants in the control group will not receive any type of treatment for a period of five weeks. After this period, they will be re-evaluated
Primary outcome measures
- General mobility [Time frame: 3 months]
