Methods: A 6-year-old hemiplegic cerebral palsied child was treated with Upper-Limb Exerciser as one of augmented visual and auditory feedback devices. Sensory Integration and Praxis test was used to measure a child’s ability to integrate sensory input for perception, motor planning, and spatial actions in;Space Visualization, Figure-Ground Perception, Standing and Walking Balance, Design Copying, Postural Praxis, Bilateral Motor Coordination, Constructional Praxis, Postrotary Nystagmus, Motor Accuracy, Sequencing Praxis, Oral Praxis, Manual Form Perception, Kinesthesia, Finger Identification, Graphethesia, Localization of Tactile Stimuli, and Praxis on Verbal Command. Results: The results revealed improvement of the major standard score for each of the 17 subtests of Sensory Integration and Praxis Test when compared after three successive treatment. Conclusion: The using upper limb exerciser as one method of augmented visual and auditory feedback can be used as one of the physical and occupational therapy programs aiming to improve praxis skills in hemiplegic cerebral palsied children.展开更多
