Association between fine motor skills and binocular visual function in children with reading difficulties

Area of Science:

• Developmental Psychology
• Neuroscience
• Ophthalmology

Background:

• Fine motor skills (FMS) in children are linked to reading achievement.
• The precise nature of the association between FMS and reading difficulties requires further investigation.

Purpose of the Study:

• To evaluate FMS in children with reading difficulties using two experimental tasks.
• To determine if FMS performance in these children correlates with diminished binocular function.

Main Methods:

• Assessed motor performance in 19 children with reading difficulties using bead-threading and peg-board tasks.
• Evaluated binocular vision, including stereoacuity, fusional vergence, amplitude of accommodation, and accommodative facility.
• Compared performance with an age- and sex-matched control group.

Main Results:

• Children with reading difficulties performed significantly worse on the bead-threading task compared to controls.
• No significant difference in peg-board task performance was observed between the groups.
• Accommodative facility was the sole binocular function measure significantly associated with motor performance.

Conclusions:

• Findings suggest that adequate binocular vision is important for optimal development of FMS and reading.
• Further research is warranted to explore the contribution of binocular vision to FMS and reading development, especially given the small sample size.
