EFFECTS OF A VISION-FOCUSED OCCUPATIONAL THERAPY PROGRAM ON VISUAL SKILLS IN PRIMARY SCHOOL CHILDREN

June 3, 2026 updated by: Merve Keskin, Medipol University

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.

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.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Visual Skills-Based Occupational Therapy Program
Participants receive a structured visual skills-based occupational therapy program twice weekly for 6 weeks in the school setting.
Behavioral: Visual Skills-Based Occupational Therapy Program
A structured occupational therapy program delivered twice weekly for 6 weeks targeting oculomotor functions, visual perception, visual scanning, eye-hand coordination, convergence, and visual-motor integration.
Active Comparator: Home Program Control
Participants continue routine school activities and receive structured home-based assignments without visual skills training.
Behavioral: Home-Based Assignment Program
Participants continue routine school activities and receive structured home-based assignments without visual skills training during the study period.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Motor-Free Visual Perception Test-3 (MVPT-3) Score
Time Frame: Baseline and 6 weeks
Visual perception will be assessed using the Motor-Free Visual Perception Test-3 (MVPT-3). Higher scores indicate better visual perception performance.
Baseline and 6 weeks

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Minnesota Handwriting Assessment (MHA) Score
Time Frame: Baseline and 6 weeks
Handwriting performance will be evaluated using the Minnesota Handwriting Assessment, including legibility and writing quality parameters.
Baseline and 6 weeks
Bruininks-Oseretsky Test of Motor Proficiency-2 Short Form (BOT-2 SF) Score
Time Frame: Baseline and 6 weeks
Motor proficiency will be assessed using the BOT-2 Short Form. Higher scores indicate better motor performance.
Baseline and 6 weeks
