3/24/2023 0 Comments Cervical vertigoIt is usually the consequence of an alteration in the integration between sensory input and motor responses. Imbalance is an objective loss of stability, with no perception of movement. The patient reports a feeling of unsteadiness, swaying or weakness, sometimes accompanied by nausea.29 While the aetiology of vertigo is vestibular, the aetiology of dizziness is very diverse.30 It can be a characteristic symptom of an alteration of the visual system, an alteration of the parietal and temporal lobes, the cerebellum, fatigue, stress, etc., as well as dysfunction or pathology of the cervical spine. In 85% of people presenting with vertigo, the origin is peripheral, with the remaining 15% being central.ĭizziness is a more ambiguous term that is described as a subjective sensation of unsteadiness with no objective loss of balance. It is classified as either peripheral vertigo, when the alteration occurs in the terminal organs of the vestibular system (utricle, saccule, semicircular canals and vestibular portion of the eighth cranial nerve), or central vertigo, when the alteration is located in the vestibular nuclei, cerebellum, perihypoglossal nucleus, and its different interconnecting tracts in the central nervous system (CNS). This type of true vertigo has its origin in the vestibular system and should be differentiated from dizziness or pseudo-vertigos of different aetiology. Vertigo can be described as a false sensation of movement that the subject experiences in relation to the environment or vice versa. It's a diagnosis of exclusion which means that other causes of dizziness have to be excluded first.ĭizziness terminology At this moment there are no diagnostic tests available to state that the dizziness of the patient has a cervicogenic origin. It occurs with certain positions and movements of the cervical spine and can be accompanied with a stiff or painful feeling in the neck. It has been defined as an a specific sensation of changed spatial orientation and disequilibrium as a consequence of a proprioceptive disorder of the cervical afferents. Cervicogenic dizziness is one of the possible causes of dizziness. Patients who suffer from dizziness can be classified into different subgroups based on different characteristics. They can be accompanied by several objective signs of sensorimotor control dysfunction such as altered cervical kinaesthetic sense, altered neck motor control patterns, altered standing balance and altered oculomotor and neck coordination. Symptoms can be very varied in patients with neck pain, and may include dizziness, light-headedness, unsteadiness, nausea and blurred vision. Pseudo-vertiginous symptoms can have a significant emotional impact and can be linked to anxiety, depression and fear-avoidance behaviours, which can have detrimental effects on prognosis. The incidence of pseudo-vertiginous symptoms (such as vertigo, dizziness, unsteadiness, light-headedness, imbalance or instability) is very high in this type of patients, ranging between 40 and 85%. 6.1.6 Nystagmus test with cervical rotationĭizziness and unsteadiness are the most common symptoms associated with neck pain, especially after a whiplash injury.
