The effect of the intervention will be assessed by comparing the results of the pre test collected in the beginning and post test after completing 4 week intervention period. |
| Intervention |
Visual perception based activities |
This study will adopt a randomized controlled trial design conducted at Chettinad Hospital and Research Institute and occupational therapy clinics in and around Chengalpattu District. A total of 50 children diagnosed with Specific Learning Disability (Dyslexia) will be selected using purposive sampling based on inclusion and exclusion criteria. Participants Children aged between 6–12 years, diagnosed with dyslexia by a qualified professional, will be included.Children with associated neurological, sensory, or psychiatric conditions will be excluded. Group Allocation Participants will be randomly assigned into: Control group (n = 25): Receiving conventional occupational therapy. Experimental group (n = 25): Receiving visual perception–based occupational therapy program. Assessment Tool Academic performance will
be assessed using the Academic Performance Rating Scale (APRS). Pre-test assessment will be conducted before the intervention, and post-test assessment will be done after completion of the intervention period. Intervention Procedure The experimental group will undergo a structured visual perception–based occupational therapy program. Each session will last 40–45minutes, conducted 3 days per week for 4 weeks. The program will include: Warm-up activities(5–10 minutes) Main visual perception activities (30 minutes) The therapeutic protocol consists of six tasks per session, including four station-based tasks focusing on visual-motor integration and motor coordination, and two activity-based tasks emphasizing visual perceptual sub-skills without motor involvement. The control group will receive conventional occupational therapy focusing on general academic skills without structured visual perception training. Outcome Measurement After 4 weeks of intervention, post-test scores will be obtained using APRS. Pre-and post-test scores within and between groups will be statistically analyzed to determine the effectiveness of the intervention. |

Brief Summary
|
This study is a randomized , parallel group , active controlled trial evaluating the effectiveness of visual perception based activities on scholastic skills among children with dyslexia . The study will be conducted at Chettinad Hospital and Research Institute and selected occupational therapy clinics in and around Chengalpattu District. A total of 50 children aged 6–12 years, diagnosed with Specific Learning Disability (Dyslexia) by a qualified professional, will be recruited using purposive sampling based on predefined inclusion and exclusion criteria. Children with associated neurological, sensory, or psychiatric conditions will be excluded. Participants will be randomly allocated into two groups: a control group (n = 25) receiving conventional occupational therapy and an experimental group (n = 25) receiving a structured visual perception–based occupational therapy program. Academic performance will be assessed using the Academic Performance Rating Scale (APRS). Pre-test assessment will be conducted prior to intervention and post-test assessment will be performed after completion of a 4-week intervention period. The experimental group will receive intervention sessions lasting 40–45 minutes, three days per week for four weeks, consisting of warm-up activities and structured visual perception tasks targeting visual-motor integration, motor coordination, and visual perceptual sub-skills. The control group will receive conventional occupational therapy focusing on general academic skills. Pre- and post-intervention scores within and between groups will be statistically analyzed to determine the effectiveness of the intervention. |
