[Comparing visual perceptual skills among 8 to 10-year-old strabismal/nonstrabismal cerebral palsy children]

Most aspects of development are dependent or guided by visual system. Defect of visual perception can cause secondary mental retardation in cerebral palsy children with normal intelligence. So, identifying the effective factors on visual perceptual skills and early treatment of them in these children can prevent learning disorders, slowing the treatment process and secondary problems. This study was designed to compare the effect of chronological age, strabismus and sex factors on visual perceptual quotient. In this cross-sectional study, 120 spastic cerebral palsy children with equal numbers of strabismal/non-strabismal disorder [age 8-10 years] were randomly selected from exceptional schools of educational departments and rehabilitation clinics of Tehran and were evaluated with the test of visual perceptual skill-revised [TVPS-R]. The results showed that the scores of visual perceptual quotient [P<0.0001] and visual perceptual age were significantly different among 8 to 10 years old children [P<0.0001]. There was no significant difference in visual perceptual quotient between two sexes [P=0.76] and that non-strabismal children had greater visual perceptual quotient compared to strabismal one [P<0.0001]. It can be concluded that age and strabismus have a significant effect on visual perceptual quotient, while this is not the case on sex

Effect of the Audiovisual tactile on Sensory Recovery Following Ulnar Nerve Repair

The aim of this study was to determine if deprivation of tactile sense could be compensated by hearing sense, early after the nerve repair in hand. This may hypothetically help to maintain the cortical hand representation during the early denervation period. [Audiovisual tactile]; apparatus was used early after repair of the ulnar nerve in order to improve recovery of hand sensibility by maintaining an active sensory map of the hand in the somatosensory cortex during the differentiations period. This tool was used in a 25- years-old man. Then sensory evaluation was performed at regular intervals in 2, 5 and 7 months after the intervention. Sensory improvement was better in the patient who used the artificial sensibility regimen compared with the others who did not. This study suggests that the onset time of sensory afferent inflow after nerve repair is a very important agent to focus on sensory re-education
