Better vision, particularly contrast sensitivity, enhances fine motor skills in individuals with normal binocular vision. This study highlights the link between visual performance and fine motor skills (FMSs).
Area of Science:
- Ophthalmology
- Neuroscience
- Human Factors Engineering
Background:
- Fine motor skills (FMSs) are crucial for daily activities.
- Visual performance significantly influences motor control.
- Understanding this relationship can inform interventions for visual and motor deficits.
Purpose of the Study:
- To investigate the correlation between FMSs and visual performance in young adults.
- To determine which visual functions most impact FMSs.
- To compare FMSs and visual performance under monocular versus binocular conditions.
Main Methods:
- Thirty participants with normal binocular vision completed five FMS tasks (pegboards, needle threading, water pouring).
- Visual performance was assessed using near visual acuity, contrast sensitivity (CS), and disability glare.
- Data were analyzed for correlations and predictive relationships between visual function and FMS performance.
Main Results:
- Binocular vision significantly improved overall visual function and FMS performance compared to monocular vision (p < 0.001).
- A positive correlation was found between overall visual performance score (OVPS) and overall fine motor skills score (OFMSS) (rho = 0.329; p = 0.010).
- Age and CS predicted 21.3% of the variance in OFMSS, with CS being the most influential visual factor.
Conclusions:
- Individuals with normal binocular vision and better near visual function demonstrate superior FMS.
- Contrast sensitivity is a key visual determinant of fine motor skill execution.
- These findings underscore the importance of visual assessment in evaluating and improving motor abilities.

Anatomical Movements
Here are some common anatomical movements:
Flexion and extension motions are in the sagittal (anterior–posterior) plane of motion. These movements take place at the shoulder, hip, elbow, knee, wrist, metacarpophalangeal,...
