People are more likely to develop chronic pain after suffering injuries in a traffic crash than after other physically traumatic events, according to a new study.
This new research, published in March in the journal “Arthritis Care & Research” found that the onset of chronic pain was more often reported following a traffic accident than from other physically traumatic triggers like workplace injury, surgery, fracture, hospitalization and childbirth.
To examine the relationship between different physically traumatic events and the onset of chronic widespread pain, researchers from the University of Aberdeen School of Medicine and Dentistry, U.K. followed 2069 participants from the Epidemiology of Functional Disorders (EPIFUND) study.
Participants in the study, a population-based prospective cohort, provided data on musculoskeletal pain and associated psychological distress at three time points over a four-year period.
Patients were also asked about their recent experience with six physically traumatic events — traffic accident, workplace injury, surgery, fracture, hospitalization and childbirth.
Of the 241 (12 percent) who reported new onset of chronic widespread pain, about one-third were more likely to report at least one traumatic event during the study period than other individuals.
After researchers adjusted for age, sex, general practice and baseline pain status, those who reported a traffic accident experienced an 84 percent increase in the likelihood of new onset chronic widespread pain. No association was observed with hospitalization, surgery or in women who gave birth.
"We believe there are persons — defined by prior physical and psychological health — who in the event of a traumatic trigger are vulnerable to developing chronic widespread pain," explained Dr. Gareth Jones, of the University of Aberdeen School of Medicine and Dentistry, U.K., and lead author of the current study. "Further research should focus on the unique aspects of an auto accident and the individual's reaction to this particular trauma that causes the increased risk of chronic widespread pain onset.”
