About this trial

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

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Individuals diagnosed with convergence insufficiency (CI);

Aged between 18 and 60 years;

Physically active individuals;

Without cognitive impairments;

Disqualifiers

Diagnosis of neurodegenerative diseases (e.g., Parkinson's, ALS);

Presence of dementia;

History of stroke;

Presence of vestibular disorders;

Trial design

Design model

Parallel

Treatments tested in this trial

  • Oculomotor therapy

    Other intervention

    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. Accommodative techniques: (1) Eccentric Circles: Printed circles with eccentric marks; viewed through filters to train motor and sensory fusion by aligning them into a single 3D image. (2) Opaque Lifesaver Cards: Cards with figures on an opaque background, used with red-green filters to stimulate convergence and fixation by reducing peripheral stimuli and enhancing visual attention.

  • No Treatment Added

    Other intervention

    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

Trial outcomes

Primary outcomes

1

General mobility

General mobility will be assessed using the Timed 'Up-and-Go' test with time measured in seconds as the unit of measurement.

Time frame
3 months

Secondary outcomes

1

Single-Leg Stance Test

The single-leg stance test is used to assess static balance and predict frailty, particularly in community-dwelling older adults. Participants will be asked to stand on one leg for a maximum of 30 seconds, first with eyes open and then with eyes closed. The duration will be measured in three trials per visual condition, and the longest time will be considered. Longer stance duration indicates better balance. The examiner will remain beside the participant to prevent any risk of falling.

Time frame
3 months
2

Postural Control Assessment

Postural control will be evaluated using a force platform (BIOMEC 400 v1.1, EMG System Ltda®). Tests will be performed under four conditions: (1) eyes open; (2) eyes closed; (3) eyes open, single-leg stance (dominant leg); and (4) eyes closed, single-leg stance (dominant leg). The main parameters will be the center of pressure (CoP) sway velocity (cm/s), in both anteroposterior (AP) and mediolateral (ML) directions.

Time frame
3 months
