Journal of Visual Impairment & Blindness

The Assessment of Computer Task Performance was developed to evaluate the performance, both in terms of speed and accuracy, of children with low vision when using sequences of actions that result in a computer command. The results with 22 students aged 4–12 showed that four standardized tasks in the test have a high degree of reliability, and one has a moderate degree.

In this study, the neck and head relative to the ground were more flexed, while the head relative to the neck was more extended, in the subjects who were blind than in the sighted subjects. The introduction of external (sound) or proprioceptive (mandibular position, look ahead) inputs modified craniocervical posture and relationships (extension) in both groups.

In this study, treatment focused on parenting practices for a 4½-year-old girl with a visual impairment caused by Leber's congenital amaurosis and problems initiating and maintaining sleep. The sleep problem was effectively treated with a graduated extinction procedure.
