Sammanfattning
Shermer’s neck was first described in 1983 in an ultra-distance cyclist and it is often associated with neck pain (in our patient diplopia as first
symptom) and exhaustion and impaired neck motor function with inability to extend the neck against gravity. The diplopia, for the first time
described in connection with Shermer’s neck, was accentuated when elevating the eyes and looking at distance, most likely reflecting exhaustion
in the elevator muscles of the eye. Shermer’s neck usually appears after 800 km of non-stop bike racing. Risk factors include former neck injuries,
staying low in aerobars for a long time, and wearing helmet light/cameras. Prevention includes neck strength training, muscle stretching, raising
of handle bars and different kinds of chin support. The most important treatment is rest and not riding a bike. In our patient the diplopia was
normalized after 4 hours of sleep. It can take 2-14 days to regain full neck motor function. The possibility of developing Shermer’s neck and
diplopia (»Berglund’s diplopia«) must be taken into account when many untrained individuals participate in popular shorter races over about 300
km.
