Le facteur E et ses caractéristiques neurophysiologiques et motrices : sont-elles modulables chez les enfants avec une paralysie cérébrale ? Une revue de la littérature

Although the current definition of cerebral palsy requires us to make a classification of children based on their motor abilities, other associated disorders, such as perceptual disturbances, may be the source of the main problem of our patients. These perceptual disturbances include the "startle response", commonly known in France as "Factor E". This reaction is a sudden and involuntary movement characterized by an opening motor pattern, although other autonomous and emotional components may be present. As the "Factor E" can directly impact on the autonomy and activities of the daily lives of our patients, the following problem arises: What neurophysiological and motor characteristics of factor E allow it to be modulated in children with cerebral palsy? A literature review on seven different databases was performed, finding five articles that meet the eligibility criteria. In general, we can affirm that "Factor E" has a motor pattern which is similar to that of the startle reflex found in lambda subjects and that it is habituated which can be rapid in patients with cerebral palsy.
