Chiropractors frequently see patients with headaches and frequently successfully provide relief, but despite many tomes on the subject of headache,1-8 there seems to be little helpful data on differential diagnosis that permits construction of an easy algorithm for those of us in clinical practice.
The taxonomy of the International Headache Society acknowledges some forms of headache can derive from pain referred from the cervical spine,9 and the neuroanatomical and physiological basis for such pain referral to the head is well-established.10-14 On the other hand, the objective diagnosis of headaches of cervical spine origin remains contentious.15 The clinical criteria outlined by the International Headache Society are not particularly persuasive and thus may not uniformly be accepted by clinicians dealing with headache. The IHS diagnostic criteria stipulate as follows:
A. Pain, referred from a source in the neck and perceived in one or more regions of the head and/or face, fulfilling criteria C and D [below].
B. Clinical, laboratory and/or imaging evidence of a disorder or lesion within the cervical spine or soft tissues of the neck known to be, or generally accepted as, a valid cause of headache.
C. Evidence that the pain can be attributed to the neck disorder or lesion based on at least one of the following:
Demonstration of clinical signs that implicate a source of pain in the neck
Abolition of headache following diagnostic blockade of a cervical structure or its nerve supply using placebo or other adequate controls
D. Pain resolves within three months after successful treatment of the causative disorder or lesion.
Even these guidelines deny a role for clinical diagnosis of cervicogenic headache. Objective confirmatory tests are lacking, too invasive or not generally available. Disorders of the upper cervical spine are implicated as a headache cause by virtue of the anatomy of the region16 and by a controlled study17 that demonstrated headaches stemming from the C2-3 zygapophysial joint could be identified by diagnostic blocks of the third occipital nerve innervating the joint.
Two authors18 propose a pragmatic diagnostic approach to probable cervicogenic headache with a list of seven clinical criteria, as well as a "rigorous approach to the diagnosis and management of definite cervical headache," such as percutaneous radiofrequency neurotomy.
Since clarity leads to power, I have mentally tossed around diagnostic options for trying to achieve such an algorithm and come up with one for me. Maybe you can work out one for yourself (or use what I've come up with). As always, thanks for thinkin' with me!

Some doctors thrive in a personality-based clinic and have a loyal following no matter what services or equipment they offer, but for most chiropractic offices who are trying to grow and expand, new equipment purchases help us stay relevant and continue to service our client base in the best, most up-to-date manner possible. So, regarding equipment purchasing: should you lease, get a bank loan, or pay cash?
Some pundits say that the upcoming presidential and congressional races, and many local races, might be the most consequential in our country’s history. We do not have the choice of sitting on the sidelines and hoping our patients will carry our water. Unlike other medical professions such as physical therapists, podiatrists, nurses, etc., the health care class (AMA) will not protect us. We must be in the game.
The most common condition affecting the shoulder is rotator-cuff disease. From acute tears to chronic tendinopathy, it’s common and needs a thorough workup. In fact, even asymptomatic shoulders can have full-thickness rotator-cuff rears in up to 40% of instances. Let’s look at additional conditions that can present to the office with weakness, loss of motion and pain in the shoulder beyond rotator-cuff tears.
