Conclusions : Despite low levels of evidence , manual examination of the cervical spine appears to aid the diagnostic process related to CGH and can be implemented by both experienced and inexperienced examiners
Objective : To evaluate the diagnostic validity of manual examination techniques used to diagnose  cervicogenic headache ( CGH ) .
Background : Cervicogenic headache is a specific type of headache that originates from the cervical spine and is typically chronic in nature .
Diagnostic criteria for CGH have been established by the International Headache Society ( IHS ) and are cited extensively in the literature .
Diagnosis of CGH through manual examination is a more recent practice .
To our knowledge , no systematic review of manual diagnosis of CGH has been performed .
The Prevalence of Cervicogenic Headache in a Random Population Sample of 20–59 Year Olds
Study Design From a r and om population sample , those experiencing frequent headaches were identified . They were examined to determine how many fulfilled the 1990 international Headache Society classification criteria for cervicogenic headache . Objective To estimate the prevalence of cervicogenic headache in the general population and in the group experiencing frequent headaches . Summary of Background Data Only with the publication of the 1990 headache classification criteria did a generally accepted clinical definition of cervicogenic headache emerge . The prevaience of this form of headache has been estimated only in two highly selected in-clinic patient population s. No data exist regading the prevalence in representative unselected population s. Methods . A short question naire on headaches  was mailed to 826 r and omly selected residents of a midsized Danish town . A group of 57 individuale in the age range 20–59 years who reported having headache episodes on 5 or more days in the previous month were identified . Forty-five of the 57 were eventually interviewed and examined with respect to the IHS criteria for cervicogenic headache ( the radiological criteria were omitted on ethical grounds ) . Results Of the 45 persons examined , eight fulfilled the diagnostic criteria for cervicogenic headache , equivalent to a prevalence in the headache group of 17.8 % ( 95 % confidence interval = 8%-32 % ) . Conclusions Cervicogenic headache appears to be a relatively common form of headache , similar to migraine in prevaience
