About

Context:

Most medical and surgical interventions for individuals with Cerebral Palsy (CP)-such as botulinum toxin injections, orthopedic surgery, and rehabilitation-occur during childhood. While these treatments are costly and resource-intensive, there is a significant lack of long-term data regarding their effectiveness in adulthood. Furthermore, the perspective of adult patients on the care they received as children is rarely documented. Understanding this "patient-centered" perspective is vital, as care aligned with an individual's values is proven to result in higher satisfaction and better health outcomes.

Problem Statement While botulinum toxin (BTX) has been the gold standard for treating focal spasticity since 2009, it is an iterative (repeated) treatment that can involve procedure-induced pain. At present, there is limited knowledge about how adults with CP perceive the long-term impact of childhood vaccinations. The emotional and physical burden of repeated treatments during development is also not well understood, as are the coping strategies developed by these individuals to manage the stress and pain associated with long-term medical care.

Objectives

The PERTOXE study is a prospective study designed to explore the transition from childhood care to adult life for individuals with CP. Its primary goals are:

Perception of Care: To evaluate how adults with CP perceive the effectiveness and impact of the botulinum toxin injections they received during childhood.

Lived Experience: To document the subjective experience of treatment, including induced pain and the quality of communication with healthcare providers.

Coping Mechanisms: To explore the "coping strategies" these individuals use to face stressful medical events and chronic functional decline.

Significance As the lifespan of individuals with CP increases, understanding long-term outcomes is a research priority. By collecting data from adults, this study aims to improve current pediatric practices, ensuring that childhood interventions better support a high quality of life, functional maintenance, and psychological well-being in adulthood.
