Dizziness and balance issues are common complaints that can be difficult to diagnose because there are many different causes. People often suffer unnecessarily because it can take some time to go through the process of exploring the various possibilities in order to determine the correct diagnosis. However, once the diagnosis is made, the condition is highly treatable. One cause of dizziness may be cervical vertigo.
What is cervical vertigo?
Cervical vertigo is dizziness that is provoked by a particular neck posture, no matter what the orientation of head with gravity. Cervical vertigo is caused by inflammation, trauma, or degenerative changes in the cervical spine or neck musculature. Symptoms may include dizziness and neck pain with head movements. It may be accompanied by tense and tight neck muscles, stiffness of the neck, as well as referred pain to the head, neck, or arms.
What causes Cervical vertigo?
Cervical vertigo tends to be a controversial topic because there are no tests to confirm the diagnosis. This diagnosis is determined after ruling out other causes of vertigo, like inner-ear disorders or problems with the central nervous system and the spine. This condition can happen after head injuries and whiplash injuries. It can occur along with brain injury or injuries to the inner ear. There are two possible explanations:
- Obstruction or pressure on the vertebral artery. The vertebral arteries travel through the neck vertebrae to enter the brain and provide the circulation to the brain structures.
- Reduced sensory information from the neck muscles to the brain. The information from the neck muscles is combined with information from the inner ear and eyes to tell the brain about our orientation in space. This altered or reduced information can cause symptoms of dizziness with certain neck postures.
Types of testing for diagnosis:
Evaluation for cervical vertigo involves a medical evaluation first. After the medical evaluation, testing of the inner-ear function and brain function is usually requested to ensure that the inner ear structures and the central structures are working properly. Following is a list of possible tests that the medical provider might order.
- Medical assessment: physical examination
- MRI of the brain and neck
- Videonystagmography (to rule out vestibular neuritis and Benign Paroxysmal Positional Vertigo)
- Hearing Test
- CT Angiography to study the blood vessels
- Neck X-Rays
- Physical Therapy Evaluation: Assessment of inner-ear function (to rule out Benign Paroxysmal Positional Vertigo)
- Computerized Dynamic Posturgraphy — performed by a trained physical therapist. This is a test of balance which determines the use of sensory inputs
Treatment Options:
Seventy-five percent of the people who suffer from true cervical vertigo with neck pain recover with physical therapy treatments. Gentler physical therapy treatments like gentle trigger-point therapy and myofascial release can help reduce the vicious cycle of neck pain and muscle tightness. Treatment techniques that use more pressure or are more vigorous can make this dizziness worse.
Treatments include:
- Medication prescribed by the physician
- Physical Therapy treatments include gentle stretching, myofascial release, and soft tissue mobilization. Modalities like electrical stimulation and ultrasound help reduce muscle tightness and enable the muscles to tolerate stretching during range-of-motion exercises.
- Education in proper sitting and sleeping posture, and proper use of neck during activities of daily living.
- Some patients need addition of vestibular rehabilitation therapy, which targets the inner ear function.
