Speed Bumps May Aid Appendicitis Diagnosis12/18/12
TUESDAY, Dec. 18 (HealthDay News) -- Speed bumps are great for
slowing down heavy-footed motorists, but they might speed up the
diagnosis of acute appendicitis, a new study says.
Although there is no specific clinical diagnostic test for
appendicitis, researchers in Great Britain found that if patients'
abdominal pain got worse while driving over speed bumps, they were
more likely to have the condition.
"It may sound odd, but asking patients whether their pain worsened going over speed bumps on their way in to [the] hospital could help doctors in a diagnosis," Dr. Helen Ashdown, of the department of primary care health sciences at the University of Oxford, said in a news release. "It turns out to be as good as many other ways of assessing people with suspected appendicitis."
The results of the study were published online Dec. 17 in the
The study, conducted by researchers from the University of
Oxford and Stoke Mandeville Hospital, involved more than 100
patients between 17 and 76 years old who went to the hospital for
The patients were divided into two groups within 24 hours of
their arrival at the hospital: speed-bump positive or speed-bump
The patients who were considered "positive" had abdominal pain
that got worse when they drove over a speed bump. Patients whose
pain got better or stayed the same traveling over a speed bump were
put into the "negative" group. Those who could not tell how the
speed bump affected their pain were also classified as
The study found 64 patients drove over a speed bump on the way
to the hospital. Of these, 84 percent were considered "speed-bump
The researchers also found that half of the patients who went
over a speed bump had a confirmed diagnosis of acute appendicitis.
Of these patients, 97 percent had pain that got worse when they hit
the speed bump.
The researchers noted that seven of the patients who were in the
"positive" group that did not have appendicitis were diagnosed with
other serious conditions such as ruptured ovarian cyst or
diverticulitis (bulging sacs or pouches typically found in the
The study's authors said the speed bump test works just as well
as other methods used by doctors to diagnose appendicitis. They
added, however, that being speed-bump positive doesn't guarantee a
diagnosis of appendicitis. Instead, the researchers concluded, the
test should be a routine part of doctors' assessment for the
Doctors currently diagnose appendicitis by looking for symptoms,
such as abdominal tenderness or swelling, during a physical
examination. When obvious signs don't exist, they also may order
