ABSTRACT
@#Objective To evaluate the effect of nerve block and nerve block combined with glycerol and fructose injection on cervicogenic headache (CEH).Methods 50 CEH patients were randomly divided into the nerve block group (n=25), received the occipital and C2 nerve block; nerve block combined with glycerol and fructose injection group (n=25), received nerve block plus glycerol and fructose injection. The pain degree (numeric rating scales, NRS) and the degree of cervical stiff measured by restriction of the range of motion of the neck (ROM) were recorded.Results NRS and ROM decreased significantly after treatment compared with the baseline in two groups ( P<0.01). NRS and ROM decreased much more in the nerve block combined with glycerol and fructose injection group than in the nerve block group ( P< 0.01).Conclusion Nerve block combined with glycerol and fructose injection is a more safe and effective method in the treatment of CEH.
