The evolution of cerebral palsy publications and global productivity: a bibliometric analysis between 1980 and 2019 Aysegul Danis1   · Muhammet Gultekin Kutluk2 Received: 23 October 2020 / Accepted: 8 November 2020 © Belgian Neurological Society 2020

Abstract Although cerebral palsy (CP), which affects the quality of life of many children and their families, is the most common cause of motor dysfunction in children, no comprehensive bibliometric study has holistically evaluated the publications on CP. This study aimed to analyze the scientific outputs published on CP in pediatrics research between 1980 and 2019 using bibliometric and statistical methods, and reveal new study trends in this field. The literature search was performed in the Web of Science database using the keyword cerebral palsy in the title section of the articles published only in the pediatrics research field. Four-thousand seventy-five publications were obtained in the field of pediatrics research on CP, 3027 of which were articles. We shared abstract information of 3027 articles published between 1980 and 2019 with this comprehensive bibliometric study, which will be a useful guide for physicians and scientists on the global outcomes of CP, and we discussed new trends in this topic. We think that comprehensive bibliometric analyzes on subjects that we frequently encounter in clinics and which are widely researched will contribute to the field.

Introduction Cerebral palsy (CP) describes a group of disorders in the development of movement and posture that are non-progressive, causing activity limitations that occur in the brain of the developing fetus or baby. Motor disorders caused by CP are often accompanied by sensory, cognitive, communication, perception, behavioral disorders, and seizures [1–3] Although the prevalence of CP varies by population, it is reported in the literature within the range of 1–5 per 1000 live births [3–5]. The prevalence of CP among children aged 2–16 years was found as 4.4 per 1000 live births in a study conducted in Turkey, it was 2.1 in Norway, and 1.88 in Japan in a study conducted in children aged 1.9–10.2 years [5–7]. * Aysegul Danis [email protected] Muhammet Gultekin Kutluk [email protected] 1

A meta-analysis examining 49 studies conducted by Oskoui et al. to determine the prevalence of CP in 2013 determined the overall prevalence as 2.11 per 1000 live births (95% confidence interval: 1.98–2.25) [4]. Bibliometry is the statistical analysis of scientific publications such as articles and books published on a subject, in the entire research area, or between certain dates [8]. In parallel with the increasing number of publications in the field of medicine in the literature
