It is unknown if applying superficial dry needling to the trigeminal innervation field improves pain and disability for patients with cervicogenic headaches. The aim of this study is to determine if superficial dry needling of the trigeminal innervation field improves pain, neck mobility, and disability in patients with cervicogenic headaches. It will also be examined if psychosocial factors such as stress, anxiety, depression and self efficacy influence improvements in pain, range of motion and neck disability.

Cervicogenic headache (CGH), is defined by the International Classification of Headache Disorders (ICHD) as a "headache caused by a disorder of the cervical spine and its component bony, disc, and/or soft tissue elements, usually but not invariably accompanied by neck pain. Prevalence of CGH in the general population is between .4-20%. Although the primary source of pain is generated from the upper cervical spinal levels, there is also neuro-anatomical basis of CGH involving the trigeminal nerve.

Dry needling (DN) is a widely used intervention performed by physical therapists for a wide range of musculoskeletal and neurological conditions. Dry needling has been shown to be beneficial for CGH but DN has only been investigated using trigger point DN to cervical musculature. Superficial DN also reduces pain associated to orthopedic spinal conditions and may be associated with a lower risk of post-treatment soreness.

Non-thrust mobilizations of the cervical spine are an accepted treatment known to reduce pain and disability associated with CGH. Their use has also been recommended in clinical practice guidelines.

This study aims to look investigate whether superficial dry needling targeting the trigeminal innervation sensory field will reduce pain and impairments known to exist in patients with CGH compared to mobilizations of the cervical spine. Mobilizations of the cervical spine are another common treatment that physical therapists employ to treat cervicogenic headaches.

Inclusion Criteria:
