Effect of Oculomotor Therapy in Individuals With Convergence Insufficiency

"Effect of Oculomotor Therapy in Individuals With Convergence Insufficiency: A Blind Randomized Clinical Trial"

The aim of this study is to investigate the effect of oculomotor therapy in individuals with ocular convergence insufficiency.

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.

Inclusion Criteria:

• Individuals diagnosed with convergence insufficiency (CI);
• Aged between 18 and 60 years;
• Physically active individuals;
• Without cognitive impairments;
• Without vestibular system impairments (e.g., dizziness).

Exclusion Criteria:

• Diagnosis of neurodegenerative diseases (e.g., Parkinson's, ALS);
• Presence of dementia;
• History of stroke;
• Presence of vestibular disorders;
• Systemic neuromuscular diseases;
• Disabling musculoskeletal pain;
• Diagnosis of diabetic polyneuropathy;
• Use of joint prostheses;
• Ongoing physical therapy treatment;
• Lack of physical ability to perform the prescribed physical activities.
