Visual-Based Training Program for Motor Functions in Cerebral Palsied Children with Cortical Visual Impairment

Abstract

Background /Aim: Cortical visual impairment (CVI) is a temporary or permanent visual dysfunction resulting from damage to the visual systems in the brain that deal with processing and integrating visual information. The aim of current study was to investigate the effect of visual- based training program on motor functions in CP children with CVI. Methods: Twenty six spastic CP children with CVI from both sex, ranged in age from 2 to 4 years, participated in this study. They were randomly assigned to two groups of equal number; control (I) and study (II) groups. Children in group I received the conventional physical and occupational therapy program inside the normally lighted room. Children in group II received the same program given to group I using visual stimulation modalities inside the sensory room. Treatment duration for both groups was 2½ hours, 3 days per week for a successive three months. Gross and fine motor functions were evaluated before and after treatment using Gross Motor Function Measure Scale (GMFM) and Peabody Developmental Motor Scale (PDMS) respectively. Findings: This study showed a statistically significant improvement of gross motor skills in both groups (P=0.001), however, a significant difference was seen between both groups, but in favor to group II (P=0.000). Regarding fine motor skills, no significant improvement was seen in group I (P=0.15) however, significant improvement was obtained in group II (0.001) after treatment. Conclusion: Training of gross and fine motor skills using visual stimulation modalities inside sensory room is effective for CP children with CIV to improve their gross and fine motor functions.
