About this study
Official title: The Effect of a Vision-Focused Occupational Therapy Program on Visual Perception and School-Based Visual-Motor Functions in Primary School Children
This randomized controlled trial aims to investigate the effects of a structured visual skills-based occupational therapy program on visual perception and school-based visual-motor functions in typically developing primary school students aged 8-10 years. Participants will be randomly assigned to either an intervention group receiving a 6-week visual skills program or a control group receiving routine school activities and home-based assignments. Outcomes including visual perception, visual-motor performance, convergence ability, and motor proficiency will be assessed before and after the intervention.
Read the detailed description
Visual skills, including visual perception, visual-motor integration, visual scanning, eye movement control, and convergence ability, are important determinants of academic performance and school participation. Previous research has demonstrated associations between visual skills and reading, writing, attention, and motor performance; however, experimental studies evaluating structured occupational therapy interventions targeting visual skills in typically developing school-aged children remain limited.
The purpose of this randomized controlled trial is to examine the effectiveness of a structured visual skills-based occupational therapy program on visual perception and school-based visual-motor functions in typically developing primary school students.
Participants aged 8-10 years attending the 3rd and 4th grades of primary school will be recruited and randomly assigned to intervention and control groups. The intervention group will receive a 6-week occupational therapy program consisting of visual skills activities focusing on oculomotor functions, visual perception, visual scanning, eye-hand coordination, and visual-motor integration. Sessions will be conducted twice weekly in the school setting.
Outcome measures include the Motor-Free Visual Perception Test-3 (MVPT-3), Minnesota Handwriting Assessment (MHA), Near Point of Convergence (NPC), and Bruininks-Oseretsky Test of Motor Proficiency-2 Short Form (BOT-2 SF). Assessments will be performed before and after the intervention period.
Findings from this study are expected to contribute to the evidence base for school-based occupational therapy interventions targeting visual skills in typically developing children.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Visual Skills-Based Occupational Therapy ProgramBehavioural
A structured occupational therapy program delivered twice weekly for 4 weeks, for a total of eight sessions, targeting oculomotor functions, visual perception, visual scanning, eye-hand coordination, convergence, and visual-motor integration.
Home-Based Assignment ProgramBehavioural
Participants continue routine school activities and receive structured home-based assignments without visual skills training during the study period.
| Study group | Role | What they receive |
|---|---|---|
| Visual Skills-Based Occupational Therapy Program | Experimental | Participants receive a structured visual skills-based occupational therapy program twice weekly for 4 weeks, for a total of eight sessions, in the school setting. Receives: Behavioral: Visual Skills-Based Occupational Therapy Program |
| Home Program Control | Active comparator | Participants continue routine school activities and receive structured home-based assignments without visual skills training. Receives: Behavioral: Home-Based Assignment Program |
What is being measured
The primary outcome is the main question the study is designed to answer.
Motor-Free Visual Perception Test-3 (MVPT-3) Score
Visual perception will be assessed using the Motor-Free Visual Perception Test-3 (MVPT-3). Higher scores indicate better visual perception performance. Visual perception will be assessed using the Motor-Free Visual Perception Test, Third Edition (MVPT-3). Total scores range from 0 to 45, with higher scores indicating better visual perceptual ability.
Measured: Baseline and 4 weeks
Secondary outcomes (2)
Minnesota Handwriting Assessment (MHA) Score
Handwriting performance will be evaluated using the Minnesota Handwriting Assessment, including legibility and writing quality parameters. Handwriting performance will be evaluated using the Minnesota Handwriting Assessment (MHA). The assessment evaluates legibility and handwriting quality. Scores range from 0 to 34 for each handwriting component, with higher scores indicating better handwriting performance.
Measured: Baseline and 4 weeks
Bruininks-Oseretsky Test of Motor Proficiency-2 Short Form (BOT-2 SF) Score
Motor proficiency will be assessed using the BOT-2 Short Form. Higher scores indicate better motor performance. Motor proficiency will be assessed using the Bruininks-Oseretsky Test of Motor Proficiency, Second Edition, Short Form (BOT-2 SF). Total point scores range from 0 to 88, with higher scores indicating better motor proficiency.
Measured: Baseline and 4 weeks
