摘要

Background

It is estimated that following acute SARS-CoV-2 infection, about 10% of people experience persistent symptoms lasting more than 3 to 4 weeks, a condition known as long COVID syndrome. Amongst its various sequelae is impairment of physical function or functional ability. Given the growing social impact of this condition, the dissemination of knowledge in this area is essential. Bibliometric analysis provides valuable information on research trends and hotspots, helping to guide future studies and inform evidence-based interventions.

Aims

The aim of this study was to conduct a bibliometric analysis of research on long COVID syndrome and Physical Function.

Method

A total of 213 single documents indexed in the Scopus (205) and WOS core collection (181) database were analysed using the traditional laws of bibliometrics.

Results

It was found that annual publications have experienced exponential growth from 2020 to 2024, based on the data available at the time of the bibliographic search. Amongst the prolific authors, four production clusters were found, with Eleuterio A. Sánchez-Romero emerging as the most productive author. Spain and Brazil were the countries with the highest number of publications. The journals of the MDPI publishing house contributed the most papers to the object of study, especially the Journal of Clinical Medicine and the International Journal of Environmental Research and Public Health. Rehabilitation, fatigue, quality of life, and exercise were four of the main keywords used by the authors.

Conclusions

The observed growth in publications suggests increasing research attention to long COVID syndrome and physical function; however, further research is still needed to establish physical function assessment protocols, patient profiles, and effective exercise-based rehabilitation programmes.
