Vestibular rehabilitation (VR), also known as vestibular rehabilitation therapy (VRT), is a specialized form of physical therapy used to treat vestibular disorders or symptoms, characterized by dizziness, vertigo, imbalance, posture, and vision. These primary symptoms can result in secondary symptoms such as nausea, fatigue, and difficulty ...
Zero gravity interferes with the vestibular system's gravity-dependent operations, so that the two systems, vestibular and visual, no longer provide a unified and coherent sensory representation. This causes unpleasant disorientation sensations often quite distinct from terrestrial motion sickness, but with similar symptoms.
Effective treatments include vestibular rehabilitation therapy, medications such as SSRIs and psychotherapy, including the most effectively represented cognitive behavioral therapy. Promising results were also found with transcranial direct-current stimulation combined with vestibular rehabilitation with significant improvement in symptoms of ...
Vestibular rehabilitation therapy is a highly effective way to substantially reduce or eliminate residual dizziness from labyrinthitis. [22] VRT works by causing the brain to use already existing neural mechanisms for adaptation, neuroplasticity , and compensation. [ 20 ]
Ototoxicity is the property of being toxic to the ear (oto-), specifically the cochlea or auditory nerve and sometimes the vestibular system, for example, as a side effect of a drug. The effects of ototoxicity can be reversible and temporary, or irreversible and permanent. It has been recognized since the 19th century. [1]
Some common side effects such as drowsiness, dry mouth, and tiredness may occur. Meclizine has been shown to have fewer dry mouth side effects than the traditional treatment for motion sickness, transdermal scopolamine. [16] A very serious allergic reaction to this drug is unlikely, but immediate medical attention should be sought if it occurs.
Surgical treatments, such as a semi-circular canal occlusion, exist for severe and persistent cases that fail vestibular rehabilitation (including particle repositioning and habituation therapy). As they carry the same risks as any neurosurgical procedure, they are reserved as last resorts.
Usually only one side is affected, and the most common symptoms are vertigo with nystagmus, loss of balance, and nausea. The symptoms are similar to those caused by some other diving injuries and differential diagnosis can be complicated and uncertain if several possible causes for the symptoms coexist.
