Clinical Scenario
It’s just started your night shift, Sara is a young EP, she is going home after an hard day. Hello - she says tired - could you help me? There is a guy with abdominal pain and nausea. I think it could be appendicitis, but there is not fever and not leukocytosis.
Have you asked if he arrived by car? - You say
No, why? 
Conclusion
Can a speed bump positive test be an effective tool for diagnosis of acute appendicitis?
Compared with classics signs and symptoms of appendicitis a speed bump negative sign performs better. On the other hand a positive test is not specific for acute appendicitis, you can find it also in other conditions like ruptured ovarian cysts or diverticulitis.
Ambulance and car drivers, take note!!!
