Conservative Management of Cervicogenic Dizziness Associated With Upper Cervical Instability and Postural Orthostatic...

Cervicogenic dizziness (CGD) is a disorder in which dizziness arises from cervical spine dysfunction and is diagnosed after excluding other conditions. We present a case of a 27-year-old woman with a six-year history of dizziness, neck and cervicothoracic pain, and occipital-temporal-orbital headaches. The patient also experienced occasional severe, incapacitating episodes of dizziness with vomiting. Previous evaluations, including advanced imaging, had helped rule out central, otolithic, and psychogenic causes of dizziness. Dynamic radiographs revealed signs of lateral instability of C1 while tilt table testing revealed postural orthostatic tachycardia syndrome (POTS). Over eight months, the patient underwent a regimen of gentle manual therapies and cervical stability exercises. The patient's dizziness substantially improved, as measured by the Dizziness Handicap Inventory (DHI), with scores reducing from 50 (moderate handicap) to 10 (less than mild handicap). This case highlights the importance of considering cervical spine dysfunction and associated conditions like POTS in the differential diagnosis of chronic dizziness. While conservative management including manual therapy appeared effective in this case for CGD with underlying upper cervical instability and POTS, additional research is needed on this topic.
