Vertebrobasilar insufficiency (VBI) describes a temporary set of symptoms due to decreased blood flow in the posterior circulation of the brain.The posterior circulation supplies the medulla, pons, midbrain, cerebellum and (in 70-80% of people) supplies the posterior cerebellar artery to the thalamus and occipital cortex.

There are several disadvantages proposed by Cohen for the classic maneuver. Patients may be too tense, for fear of producing vertigo symptoms, which can prevent the necessary brisk passive movements for the test. A subject must have adequate cervical spine range of motion to allow neck extension, as well as trunk and hip range of motion to lie ...
Then the patient is quickly lowered into a supine position (on the back), with the head held approximately in a 30-degree neck extension (Dix-Hallpike position), with the head remaining rotated to the side. The clinician observes the patient's eyes for "primary stage" nystagmus. The patient remains in this position for approximately 1–2 minutes.
The Vertebral Artery Test or Wallenberg Test is a physical exam for vertebral artery insufficiency.. Commonly, the VA test involves cervical spine motion to an end-range position of rotation, extension or a combination of both.

Delayed onset Lhermitte's sign has been reported following head and/or neck trauma. [9] [10] This occurs ~2 1/2 months following injury, without associated neurological symptoms or pain, and typically resolves within 1 year. [citation needed]
Manipulation of neck by chiropractor: For example, vertigo symptoms can be relieved [25] Neck braces to avoid movement of neck and provide stability; Physical therapy; Injection: Combination (anesthetic and cortisone) drug to help alleviate the pain; Surgery to restore function and form of the spine; Cervical spinal cord stimulation (cSCS) [26]
Occipital neuralgia is caused by damage to the occipital nerves, which can arise from trauma (usually concussive or cervical), physical stress on the nerve, repetitive neck contraction, flexion or extension, and/or as a result of medical complications (such as osteochondroma, a benign bone tumour).
