The program targeted three components of the ocular motor system through instructional videos that children followed at home. Participants practiced rapid eye movements between fixed points, known as saccades; smooth pursuit exercises, which involve smoothly tracking moving targets; and combined head-and-eye movements based on the vestibulo-ocular reflex, the reflexive mechanism that stabilizes gaze during head motion. The researchers reasoned that repeated, moderate stimulation of the eye-movement system during childhood—a stage when balance control and visual skills develop alongside the maturation of sensory and motor systems—might support visual function in this age group.

A central challenge in evaluating such programs is verifying whether children actually perform the prescribed exercises. Few previous studies have objectively monitored adherence to long-term, home-based eye-movement training in this age group. To address this gap, the team employed the SUKUBARA remote monitoring system, which recorded each participant’s video viewing time and thereby enabled an objective assessment of training frequency rather than relying solely on self-report.

After the 24-week program, the researchers observed gains in eye-hand coordination and in the children’s ability to identify digits moving horizontally across the visual field. Improvements in eye-hand coordination tended to be greater among children who trained more frequently, a pattern consistent with a possible relationship between training dose and benefit, though the study design cannot establish causation. The program’s primary outcome measure, however, showed no significant change: balance ability, assessed with the Index of Postability, did not improve significantly over the training period.

As a single-group pilot study without a control group, the research cannot conclusively attribute the observed changes to the training itself, since developmental progress or practice effects could contribute to the results. The researchers note that the findings suggest sustained, home-based eye-movement training is feasible for school-age children and may be associated with improvements in certain aspects of visual function, while the absence of a significant change in the primary balance outcome tempers the interpretation of the program’s overall effectiveness.
