Clinical Evaluation of Functional Vision Assessment by Utilizing the Visual Evoked Potential Device for Cerebral Palsy Rehabilitation

Abstract

Cerebral Palsy (CP) is developmental brain abnormalities which is prior to birth or during birth and after delivery. Cerebral brain damage cells which leads to other health issues such as vision, hearing, and motor activities and so on. The major health issues for the cerebral palsy children such as vision problem. The proposed approach is used to measure and quantify the performance evaluation of Functional Vision Assessments for the disabled children examination with CP. Analyzed the Improvement of Vision of CP children by Visually Evoked Potential (VEP) device used for before and after the therapy Process in CP Rehabilitation. This method is performed with ophthalmological device together with Functional Vision Questionnaire and evaluate the assessment were completely regarding Twenty Five children (20 males,5 females, age range between 1-11years; motor disability activity classification function system (GMFCS) level V; Manual disability activity classification function system level V)who have been recognized with CP(80% spastic quadriplegia,7%athetoid quadriplegia,10%mixed type,3% hemiplegic). All CP children had motor and intellectual incapacity and failure to impart reliably through either visual or verbal correspondence. As the Results, the significant difference is found in the VEP for the CP children and controls analyzed with the parameter measurement of mean latency and mean amplitudes between them. Abnormal VEP in children with CP exhibited a connection with the nearness of direct to extreme delayed developmental Growth. The Major of the Visual Functional Assessment of CP children which were assessed in Rehabilitation Center, activities of CP children are performed in rehabilitation center and found the good response from item given to the CP children. The proposed one which achieve the diagnostic performance by Functional Questionnaire routine vision assessment of children with CP and also the utilizing of ophthalmological device VEP for evaluating the performance of Vision development. The neurophysiologic investigations of VEP they can serve as essential tool in the clinical work up of CP children. So, conclude that the VEP device is used as a clinical purpose for quantitative evaluation of visual acuity in children with neurological or visual impairment. The VEP measurement is showed good improvement in amplitude and latency of the waveform in two children with CP.
